INTERNATIONAL PATENT CLASS- B60L01304

Maglev propulsion systems commonly employ either synchronous fields with a serpentine winding or a linear induction motor winding. Another alternative is a simpler heliical winding, the current for which is injected via a sliding contact. Long stator machines are forced to excite a lot more track than is required at any time and to place expensive switch gear along the track. Short stator induction machines are forced to perform much of the power handling on the vehicle and to deal with entry drag effects. A brush on the vehicle excites a helix winding on the track and eliminates both problems and uses the same magnetic field employed to get lift and guidance to supply propulsion. Because only a small section of the track is excited at a time, the efficiency is very high.
EXEMPLARY CLAIMS- I claim as follows: 1: A magnetic propulsion, levitation and guidance system comprising: a vehicle ; a track, said track comprising a helix winding; at least one brush mounted on said vehicle and connected to a source of electrical current, said brush being in slidable contact with said helix winding and being configured to inject said electrical current into said helix winding; and at least one source of magnetic field, said source being mounted on said vehicle , wherein when said electrical current is injected into said helix winding, said helix winding and said source of magnetic field interact to generate lift, propulsion and guidance for said vehicle .

A new method is described to produce directional currents in the space lattice, the fundamental fabric of the universe. The currents may be unidirectional or vortexual in nature and are suitable for propulsion or the generation of electric power. For propulsion, the unidirectional currents are induced by charging capacitors possessing suitable geometries. This will allow the manufacture of vehicles capable of levitation and flight. The vortexual space lattice currents are produced in a suitable pyramid when electrostatic and magnetic fields interact transversally. The vortex causes charge separation and current in the coil wrapped around the pyramid.
EXEMPLARY CLAIMS- I claim: 1: A method producing directional currents in the space lattice utilizing: (a) separated electric charges; and (b) the interaction of electrostatic and magnetic fields.

The proposed Self-Regulating System of High Speed Ground Transportation Based on Permanent Magnets designated for magnetic levitation , stabilization, and propulsion of vehicles moving with high speed without friction. The proposed system comprises two functionally connected and interacting with each other subsystems: (a) a Magneto-Dynamic Levitation and Stabilizing Self-Regulating System (MDLSS), and (b) a Permanent Magnet Linear Synchronous Motor (PMLSM). Both systems comprise permanent magnets and steel cores, MDLSS provides levitation and stabilization of a vehicle suspended in magnetic field produced by its own permanent magnets while PMLSM produces propulsion force providing the assigned alternative velocity of the vehicle along the designated trajectory of the guideway by interaction of the magnetic field of the vehicle magnets with the current traveling wave in the stator winding powered by the current of constant frequency. Each of said subsystems comprises two main parts: a fixed guideway/stator (which is common for both subsystems) including extended steel cores of MDLSS and extended three-phase windings of PMLSM, and moving together with the vehicle permanent magnets of the levitator of MDLSS and permanent magnets with steel cores of the rotor of PMLSM. Each of the subsystems is self-regulating and operates without fast response control system.

A communication passage between carriage bodies of a track-bound vehicle , especially of a magnetic-cushion train , with doors which are assigned to adjacent end walls of the carriage bodies and which, guided on the carriage bodies, serve for the closure of passage apertures located in the end walls, is to be modified to the fact that, even with a considerable inclination of the carriage bodies relative to the longitudinal axis, each of the two doors assigned to the communication passage can be opened with only little force counter to the effect of the descending force of the slope. This problem is solved, according to the invention, by making the doors movable in opposition and by coupling them by means of at least one transmission element passing through the end walls of the carriage bodies and the space between the carriage bodies. In this way, the descending forces of the slope emanating from the two doors are absorbed by the transmission element acting as an abutment, in conjunction with the carriage bodies, so that, in order to actuate the doors, only a little force is needed to overcome the friction, provided that they have an identical construction.

PROBLEM TO BE SOLVED: To provide an object levitated by magnetic attraction small in leakage magnetic flux and energy and simple in constitution without requiring positional or magnetic control system such as a magnet or a coil on the rail, which is applicable to various purposes such as a vehicle , transportation, or for exhibition and toys.
SOLUTION: In a magnetic assembly 5 having magnets facing each other in a U frame, a magnetic rail 1 is disposed at the center of the gap between the magnets 6, 6. When a part of the permanent magnets 6, 6 is moved past the lower end of the magnetic rail 1 by the load 8, attraction is generated to pull up the magnet system 5. The whole system is levitated to the position where this attraction and the load weight balances. As the magnetic assembly 5 has legs 7, it can move in the length direction of the magnetic rail 1 with a small drag.

PROBLEM TO BE SOLVED: To lower the generated electromagnetic force of a current collecting coil and restrain the vibration of an outer tank by mounting a current collecting coil at a position where electromagnetic force working on the ground coil side surface of the outer tank in the external direction becomes weak.
SOLUTION: Four current collecting coils 311 to 314, 321 to 324, 331 to 334, 341 to 344 are mounted, respectively, at equal intervals for superconducting coils 11 to 14. If the disposing distance of the superconducting coils is L, a pitch (b) for disposing current collecting coils 30 is 1350 mm/4 = 337.5 mm. The pitch (b) becomes smaller than a pitch of 2/3 of the cycle of harmonic generated at the surface of an outer tank. With this constitution, a boundary between the current collecting coil is positioned near a boundary 26 between race track superconducting coils, and the perpendicular conductor of the current collecting coil 30 is not installed on the arc part of the superconducting coil where the outward electromagnetic force of the outer tank is maximum, thus it is possible to lower outward electromagnetic force working on the current collecting coil 30.

PROBLEM TO BE SOLVED: To reduce eddy current loss generated at an 8-shaped floating coil, by shifting the floating coil and a single-layer propellant coil in the traveling direction for disposition.
SOLUTION: An 8-shaped floating coil 1 and a single-layer propellant coil 2 are arranged in parallel along the traveling direction of a vehicle . A perpendicular side 3 of the 8-shaped floating coil 1 and a perpendicular side 4 of the single-layer propellant coil 2 are shifted in the propulsion direction for disposition.

PURPOSE: To use semi-permanent levitation and thrust by magnetic force to run wheels, convert the thrust into rotating force to generate electric power, and utilize the thrust as a driving force for various applications.
CONSTITUTION: Magnets are at times placed on a magnet fixed board 1 in heteropolar series (N/S, N/S,...) or at times arranged in parallel with the north poles or south poles facing upward. Thus a magnet plate (mobile magnet) 4, the width of which is the same as the width of the fixed magnet fixed array, is positioned above the fixed magnet fixed array at an angle with respect to the fixed magnet face and with a certain distance between the magnet plate and the fixed magnet face and the magnet plate can be moved or rotated in this state. A guide wall is formed on both the sides of a vehicle for travel, so that the vehicle can be moved or fixed between them. For a rotating force, a magnetic reaction propeller is installed on a rotary shaft in such a manner that the propeller can be moved, and thus driving force produced by the fixed magnet and the mobile magnet acting on each other is converted into a rotating force.

PROBLEM TO BE SOLVED: To assemble load supporting materials of inner vessels in less numbers, by providing the load supporting materials on a first line which connects the centers of two facing sides of four sides around a surface of an outer vessel which is parallel with a coil surface, and on a second line which connects the centers of other two facing sides.
SOLUTION: Flexible load supporting materials 30 of an inner vessel 2 is provided on a first line 96 which connects each central part of two facing sides of four sides which construct a peripheral of a surface of an outer vessel 4 which is parallel with a coil surface 41, and on a second line 97 which connects each central part of other two facing sides. By the means in the case of the outer vessel 4 being deformed by bending, a position of the flexible load supporting materials 30 becomes to be a turning point of oscillation, and the flexible load supporting materials 30 does not conducts lateral oscillation. Therefore a deformation by bending of the outer vessel 4 is hardly conducted to the inner vessel 2. Therefore, the inner vessel 2 has an effect of suppressing heat generation caused by the deformation, without generating tortional deformation caused by tortional oscillation of the outer vessel 4.

PROBLEM TO BE SOLVED: To prevent any ill effect exerted on the running performance of a magnetic levitation rolling stock by end effect thereon by enabling adjustment on load distribution effected to plural electromagnets loaded on a vehicle .
SOLUTION: When air springs are used as car body supporters, their supporting force is determined by a product consisting of their effective sectional area and air pressure. By making the diameter of air springs 3 set on both end parts of a vehicle body smaller than those of other air springs 4, effective section areas are made small. By means of such contrivance, load share allotted to electromagnets arranged on a car body end part for reducing the levitating force of electromagnets due to end effect during run of a magnetic levitation rolling stock is reduced and capability of other electromagnets can be exhibited without any loss. Since such vehicles are normally run in both left and right directions, the diameters of total four air springs 3 arranged on both end parts of a vehicle body are made small.

PURPOSE: To increase the utilization factor of the generated magnetic line of force by mixing a magnetic substance for increasing permeability into a concrete body, using the horizontal plane including the central line in the vertical directions of a ground coil for levitation guide as a boundary plane, and setting the rate of the magnetic substance mixed into the upper-side concrete so that the rate is larger than the rate on the lower side.
CONSTITUTION: A magnetic substance is mixed into a concrete body 3 in a running path. At this time, the horizontal plane including the central line in the vertical direction of a ground coil 5 for levitation guide is made to be the boundary plane. The rate of the magnetic substance, which is mixed into the upper-side concrete, is made larger than the lower-side rate. Thus, a superconducting magnet 8 receives the attraction toward the upper position. That is to say, a vehicle 7 receives the stronger levitation force than in the case of the constitution, wherein the rate of the magnetic substance mixed in the concrete body 3 becomes uniform. Therefore, the utilization factor of the magnetic line of force generated from the superconducting magnet 8 is increased, and the levitation/guiding force and the propulsing force can be increased.

PURPOSE: To constantly provide an optimum vehicle condition by controlling each superconductive magnet to move the center of an on-vehicle superconductive magnet to the position lower than the null flux on the ground side coil in advance at the time of wheel running when a railway vehicle is shifted from wheel running to magnetic levitation running and to return it to the original position after it is switched over to levitation running.
CONSTITUTION: Normally, the central position of an on-vehicle superconductive magnet 8 and the position of the null flux of a ground side coil are adjusted to conform to each other so that magnetic drag may not be developed during wheel running. Running speed obtained by a transmission unit 1 is observed during wheel running and a superconductive magnet elevation control unit 3 is gradually moved so that it may come in a position lower than that of the null flux by a hydraulic motor 5 in accordance with the command of a running resistance regulation unit 2 at a point of time when it has approached the target speed of switching over to leviation running. The supporting wheels are then lifted to the body side by a supporting wheel moving motor 11 and switched over to levitation running. When it can be switched over to the leviation running, the superconductive magnet is returned to its position by synchronizing it with the lifting of the supporting wheels.

PURPOSE: To provide a magnetic levitation vehicle which is small in power consumption and high in stability of control on floating height.
CONSTITUTION: The weight information on a magnetic levitation vehicle is sent from the outside to an adjuster 12 by a communication device 11, and here the floating height where the attraction of the permanent magnet contained in a magnet 6 for floating and the weight balance each other is decided, and a DC signal source 13 automatically sets and outputs a signal corresponding to it. The electromagnet of the magnet 6 is excited so that the deviation of this output from the detection value of a gap sensor 7 may be zero, so there is no influence of noise. Moreover, it follows that a slight current flows to the electromagnet only at the time of change of set value and the time of absorption of deviation.

PURPOSE: To provide a side shifter which can shift a magnetically levitated vehicle stably without contact with the lead rail perpendicular to the main track rail by restricting it by magnetic force and can also return it to the main track without hindrance.
CONSTITUTION: The gap set value is changed from large to small toward the goal value when bringing an electromagnet 5 together with a gap sensor 4 close to a levitated vehicle 9 with a drive mechanism 6 so as to restrict the vehicle , and it is changed from small to large when pulling off the electromagnet by the lifting of the restriction, using an object, where a gap adjuster is added to a control circuit for exciting the coil of the electromagnet counterposed to a permanent magnet 11 so that the deviation of the detected gap by the gap sensor 4 from the set gap may be zero, as the lead controller 7 of a side shifter 8. According to this constitution, even when the gap is large, the deviation is small, and excessive attraction does not occur. Moreover, at separation of the electromagnet, it becomes the repulsion control, so smooth and stable shifting can be performed.

PURPOSE: To improve controllability of a magnetic levitation runner in which a composite magnet obtained by vertically superposing a permanent magnet and an electromagnet is applied.
CONSTITUTION: A composite magnet 1 has an electromagnet 2, a pair of permanent magnets 3a, 3b and a pair of iron pieces 4a, 4b. The piece 4a performs a role of making a magnetic field of the magnet 3a substantially uniform between the piece 4a and a magnetic rail 21. Thus, even when the field of the magnet 3a and the field of the magnet 2 are superposed, a uniform magnetic field is generated. Of course, a magnetic field between the other piece 4b and the rail 21 can be similar except that a direction of a magnetic flux becomes reverse. Thus, a magnetic force of the magnet 1 can be easily balanced with a weight of a vehicle 25, and the vehicle 25 can be stably levitated to improve its controllability.

PURPOSE: To efficiently move a vehicle forward by a reaction of compressed air which is sucked from a front inlet of a linear motor car moving at a high speed by magnetic levitation and is jetted from an outlet on the bottom surface of a vehicle to a plurality of projected objects installed in the moving direction on a runway surface.
CONSTITUTION: A vehicle 13 moves forward with magnetic levitation created by electromagnets installed on the vehicle and S-poles 2 and N-poles 3 of permanent magnets disposed alternately on start walls 11 at both the sides. Air sucked from two air inlets 15 on the front surface of the vehicle 13 formed to a streamline is jetted backward diagonally from the outlet 17 through an airway where the pressure varies as the sectional area gradually decreases. A plurality of projected portions 18 each having an isosceles triangle and an apex angle 21 with the bottom side 20 of the section are arranged in two rows on the runway 10 in longitudinal direction. Air jetted out from the outlet 17 hits the sloped surface of the projected portion 18, and the vehicle 13 is accelerated by its reaction. By doing this, a vortex o air in front of the vehicle can be prevented and a highly efficient running can be achieved.

PURPOSE: To make smooth train operation possible by extending a border toward the side of a preceding current feeding section, when a train is not in the assigned sections of a substation which divides a line into a plurality, and by extending the border to the side of a preceding train , till the distance up to the border being on the side of the preceding train becomes a stoppable distance, when a train is on the line.
CONSTITUTION: Each of a plurality of substations 1, 2,... along a line has a plurality of current feeding sections assigned. A border of a current feeding section assigned is moved upstream or downstream, by causing a border varying switch controller 9 to control border varying switches 5. A plurality of train position detecting devices 9 along the line detect the existence of trains in each current feeding section every moment, and input them into the border varying switch controller 9. When a train is not in sections assigned, the upstream-side border is moved to the upstream side. Besides, when a preceding train 6 and the following train 7 are on the line, for example, downstream borders of individual trains 6 and 7 are extended up to stoppable distances of the trains 6 and 7. Consequently, individual trains are operated smoothly at specified speeds.

An integrated MAGLEV ( Magnetic Levitated Vehicle ) system consists of permanent or preferably superconducting vehicle-mounted magnets which interact with both active and induced track-based currents. The magnets on the vehicle which are used for propulsion serve the dual purpose of realizing both levitation and lateral stabilization (guidance). The contribution offered by this invention is that it is able to provide propulsion, levitation , and guidance using a single type of track-based coil interacting with a singular type of magnetic field which is affixed to the vehicle . The realization of multiple functions with a single coil reduces the cost and enhances the efficiency of this MAGLEV system. In the main embodiment of this invention, propulsion currents are injected into brushes sliding along brush contact surfaces on the rail, series winding further eliminates the intermediate brushes leaving only the leading set of brushes and the trailing set. Motion induced currents in the coils realize both the necessary levitation and guidance forces for the vehicle . The propulsion system is a linear DC motor and requires no power handling along the track. Necessary operating power can either be carried on the vehicle or collected by a third rail pickup system. All coils in the track are supported by a reinforced recycled plastic matrix (polyvinyl fiberglass) or similar material.
EXEMPLARY CLAIMS- 1. A system for transportation using magnetic levitation , comprising:..(a) a vehicle ; ..(b) a track, said track comprising at least a first set of coils and a second set of coils, said first set of coils being phase shifted from said second set of coils; (c) at least two sets of brushes and at least two sets of collector plates, said brushes and said collector plates are configured to deliver current to said two sets of coils; and, ..(d) a magnetic field source, said source mounted to said vehicle , wherein said brushes are positive when delivering current to a first set of said at least two sets of collector plates and are negative when delivering current to a second set of said at least two sets of collector plates, wherein a first set of said brushes leads said magnetic field source and a second set of said brushes lags said magnetic field source, and wherein said two sets of coils and said magnetic source interact to provide a propulsion force for said vehicle when current is delivered to said two sets of coils through said two sets of brushes and said two sets of collector plates, said magnetic source and said two sets of coils further interacting so as to induce forces for levitation and guidance of said vehicle .

The magnetic levitation system for long distance delivery of water includes a magnetic levitation guideway and a magnetic levitation train of vehicles for carrying large amounts of water at high speed. Vehicles of the water train have a large, flexible balloon having a thick skin formed of reinforced flexible composite material for carrying water. When pressurized and filled with water, the container forms a streamlined cylinder that runs the full length of the vehicle . After delivery of the water load and depressurization, the flexible skins are depressurized and collapsed to minimize the frontal area and air drag on the vehicles . An "iron lift"guideway panel provides the magnetic lift force, with superconducting magnets on the vehicle attracted upwards to laminated steel plates attached to the guideway. Null flux aluminum loops provided for inherent stabilization. Unstable horizontal attractive forces are countered by null flux stability loop circuits making the stable restoring force from the null flux loops greater than the unstable force from the attraction to the steel plates, so that the net horizontal force is restoring, and the suspension is horizontally stable.
EXEMPLARY CLAIMS- Claim- 1. A magnetic levitation system for long distance delivery of water, comprising: a vehicle having magnets for providing magnetic levitation of said vehicle ; an electromagnetic induction levitation guideway providing magnetic levitation for said vehicle , said guideway including a guideway panel bearing steel members to which said magnets of said vehicle are attracted to provide vertical lift to said vehicle , said vehicle adapted to travel in a longitudinal direction along said guideway; and a flexible container mounted to said vehicle , said flexible container adapted to be inflated with water for transport and delivery of water by said vehicle.

An integrated MAGLEV ( Magnetic Levitated Vehicle ) system consists of permanent or preferably superconducting vehicle-mounted magnets which interact with both active and induced track-based currents. The magnets on the vehicle which are used for propulsion serve the dual purpose of realizing both levitation and lateral stabilization (guidance). The contribution offered by this invention is that it is able to provide propulsion, levitation , and guidance using a single type of track-based coil interacting with a singular type of magnetic field which is affixed to the vehicle . The realization of multiple functions with a single coil reduces the cost and enhances the efficiency of this MAGLEV system. In the main embodiment of this invention, propulsion currents are injected into brushes sliding along brush contact surfaces on the rail. Motion induced currents in the coils realize both the necessary levitation and guidance forces for the vehicle . The propulsion system is basically a linear DC motor and requires no power handling along the track. Necessary operating power can either be carried on the vehicle or collected by a third rail pickup system. All coils in the track are supported by a reinforced recycled plastic matrix (polyvinyl fiberglass) or similar material.
EXEMPLARY CLAIMS- Claim- 1. A system for transportation using magnetic levitation , comprising: (a) a vehicle ; (b) a track, said track having at least one composite coil, said composite coil having four subcoils electrically connected in parallel; (c) means for delivering current to said composite coil; and, (d) a magnetic field source, said magnetic field source comprising at least one set of magnets, said magnets being vertically stacked, said vertically stacked magnets facing said composite coil, the magnetic poles of said vertically stacked magnets being arranged such that magnetic pole faces of adjacent magnets alternate in polarity, said magnetic field source mounted to said vehicle , said composite coil and said magnetic field source configured such that said composite coil and said magnetic field source interact to provide a propulsion force for said vehicle when current is delivered to said composite coil, and said magnetic field source and said composite coil further interacting so as to induce forces for the levitation and guidance of said vehicle upon changes in the relative positions of said magnetic field source and said composite coil.

An electrodynamic suspension system levitates a platform or a transportation vehicle by an array of onboard superconducting electromagnetic coils forming a primary member overlying a secondary member on the guideway in a transverse flux orientation with respect to a plane of levitation of the moveable member above the secondary member on the guideway. The superconducting coils are energized by alternating current to produce an alternating field of magnetic flux. The frequency of the alternating current is selectable down to direct current. The frequency is selected to cause the vehicle to be levitated statically above the guideway. Once levitated the frequency is reduced as the speed of the vehicle increases along the guideway usually not in excess of 60 miles per hour. Passive electrically conductive plates form the secondary member to respond to the alternating field of magnetic flux and both guide and levitate the vehicle by inherently-stable repulsive induction action to maintain a controllable spaced relation between the guideway and the vehicle .
EXEMPLARY CLAIMS- Claim- 1. An electrodynamic suspension system including a magnetically levitated vehicle and a guideway one of which includes at least one cryogenically cooled electromagnetic coil forming a primary and the other of which includes a passive electrically conductive secondary, said primary and secondary member forming a magnetic circuit such that the secondary member cuts the flux lines produced by the primary member, said electromagnetic coil being energized by an electrical current having an alternating frequency to produce an alternating field of magnetic flux and a magneto-motive force which induces an alternating current in said secondary member to levitate the vehicle statically and during at least initial forward movement relative to the guideway by magnetic induction action at an air gap from the guideway, the vehicle being levitated by said alternating field of magnetic flux independently of forward velocity of propulsive vehicle movement and when the vehicle has either no longitudinal movement or when the vehicle longitudinal movement is insufficient to utilize a speed induced alternating current existing in the secondary for levitation .

The invention provides an elevator system for controlling movement of an elevator car with respect to guide rails in an elevator hoistway, having a force-estimation or position-scheduled current command controller and a magnet driver circuit without the need for a flux sensor. The force-estimation or position-scheduled current command controller responds to a force command signal, and further responds to a sensed gap signal, for providing a force-estimation or position-scheduled current command controller signal as a current command to the magnet driver circuit. The magnet driver circuit responds to the force-estimation or position-scheduled current command controller signal, for providing a magnet driver circuit signal to control said horizontal movement of the elevator car with respect to the guide rail in the elevator hoistway, whereby the horizontal movement of the elevator car is controlled without sensing magnetic flux. Other applications include any system that uses an electromagnet to produce an attractive or repulsive force across a large air gap, such as magnetic levitation trains or shuttles, and magnetic bearings.
EXEMPLARY CLAIMS- Claim- 1. An elevator system for controlling horizontal movement of an elevator car with respect to guide rails in an elevator hoistway with electromagnets of the elevator car, comprising: a force-estimation or position-scheduled current command controller, responsive to a desired force command signal containing sensed position feedback control information sensed without sensing magnetic flux between pole faces of the electromagnets and the guide rails and containing sensed acceleration feedback control information, said force-estimation or position-scheduled current command controller further responsive to a sensed gap signal containing information about actual gaps between electromagnets of the elevator car and the guide rails, for providing a force-estimation or position-scheduled current command controller signal; and a magnet driver circuit, responsive to the force-estimation or position-scheduled current command controller signal, for providing a magnet driver circuit signal to control the horizontal movement of the elevator car with respect to the guide rails in the elevator hoistway.

In a method for measuring a distance between a conducting reaction track and a functional surface moving relative to the reaction track a sensor with two signal transmitters is provided on the functional surface. An alternating field is generated in the sensor. The alternating field changes as a function of the distance between the conducting reaction track and the functional surface. Each of the two signal transmitters detects the changes of the alternating field as distance information. Each signal transmitter produces decoupled distance information values. These decoupled distance information values are processed in separate distance measuring channels to provide processed signals. The processed signals are constantly fed to and compared in a comparator. A distance information signal is emitted only when the processed signals of the separate distance measuring channels are identical within a predetermined tolerance range.
EXEMPLARY CLAIMS- Claim- 4. A sensor for detecting movement parameters of a functional surface to which said sensor is connected relative to a reaction track having profilings, said sensor comprising: at least one measuring coil for detecting a distance to the reaction track; an alternating current generator for supplying said measuring coil with alternating current, wherein the alternating current produces an alternating field in said measuring coil and wherein the alternating field changes as a function of the distance to the reaction track; said measuring coil having first strip conductor sections extending in a direction of extension of the profilings in a first plane and second strip conductor sections extending perpendicular to the direction of extension of the profilings in a second plane; said first and second planes spaced from one another in a direction perpendicular to a longitudinal extension of said reaction track.

Repelling magnetic forces are produced by the interaction of a flux-concentrated magnetic field (produced by permanent magnets or electromagnets) with an inductively loaded closed electric circuit. When one such element moves with respect to the other, a current is induced in the circuit. This current then interacts back on the field to produce a repelling force. These repelling magnetic forces are applied to magnetically levitate a moving object such as a train car. The power required to levitate a train of such cars is drawn from the motional energy of the train itself, and typically represents only a percent or two of the several megawatts of power required to overcome aerodynamic drag at high speeds.
EXEMPLARY CLAIMS- Claim- 1. A magnetic levitation system, comprising: a plurality of pole assemblies attached to a movable object; a track; a plurality of closed inductively loaded circuits connected to said track; and means for automatic centering of said movable object on said track; wherein said plurality of pole assemblies are magnetically connected to said plurality of closed inductively loaded circuits, wherein said plurality of closed inductively loaded circuits comprise a linear array of closed inductively loaded circuits, wherein a force exerted between a single pole assembly of said plurality of pole assemblies and a single circuit of said linear array of closed inductively loaded circuits is: ? F = lambda 4 pi L/C (B sub 0w) sup 2L sub 0exp(-2ky)Newtons,? where lambda is the length of one period of said array, B sub 0 is the magnetic field of one circuit of said circuits, w is the width of said circuit, L sub 0 is the inductance (in henrys) of said circuit, k = 2 pi L/C / lambda and y is a displacement in the direction perpendicular to the face of said array.

An electrodynamic suspension system levitates a platform or a transportation vehicle by an array of onboard superconducting electromagnetic coils forming a primary member overlying a secondary member on the guideway in a transverse flux orientation with respect to a plane of levitation of the moveable member above the secondary member on the guideway. The superconducting coils are energized by alternating current to produce an alternating field of magnetic flux. The frequency of the alternating current is selectable down to direct current. The frequency is selected to cause the vehicle to be levitated statically above the guideway. Once levitated the frequency is reduced as the speed of the vehicle increases along the guideway usually not in excess of 60 miles per hour. Passive electrically conductive plates form the secondary member to respond to the alternating field of magnetic flux and both guide and levitate the vehicle by inherently-stable repulsive induction action to maintain a controllable spaced relation between the guideway and the vehicle .
EXEMPLARY CLAIMS- Claim- 1. An electrodynamic suspension system including a moveable member for levitation relative to a foundation, said moveable member including at least one onboard superconducting electromagnetic coil forming a primary member overlying a secondary member on a foundation in a transverse flux orientation with respect to a of levitation of said moveable member above said secondary member on said foundation, said at least one superconducting coil being energized by a variable alternating current to produce an alternating field of magnetic flux, said foundation including passive electrically conductive means forming said secondary member responsive to said alternating field of magnetic flux which induces an alternating current in said secondary member to guide and levitate the moveable member by repulsive induction action to maintain a controllable spaced relation between the foundation and moveable member.

The proposed Magneto-Dynamic Levitation and Stabilizing Self-Regulating System (MDLSS) is designated for the stable flight of a heavy body along a given trajectory and can be employed for the magnetic levitation of vehicles and cars in high-speed ground transportation systems and for self-regulating magnetic bearings, various devices for ground acceleration, and also in the launching of space ships, missiles, and other technologies. The MDLSS system includes identical unique units connected rigidly with each other by non-magnetic ties and oriented relative to each other such that de-stabilizing forces created in one unit are compensated by stabilizing forces created in another unit once the equilibrium has been violated. Each of the units contains two extended steel cores (C-shaped in their cross-section), both lateral surfaces of which are covered by non-magnetic metallic screens, and a magnet assembly placed symmetrically in the air gap between the tips of the cores. The de-stabilizing forces are substantially decreased and the stabilizing forces are considerably increased, due to sharpening of the tips, using the saturated steel in the backs of the cores, and employing non-linear magnetic features of the saturated steel.
EXEMPLARY CLAIMS- Claim- 1. A Magneto-Dynamic Levitation and Stabilizing Self-Regulating System (MDLSS), comprising at least one unit, said unit comprising: a stator assembly and a levitator assembly magnetically coupled to the stator assembly and movable with respect thereto; wherein said stator assembly includes a pair of substantially identical elongated laminated steel cores, each including a back and a pair of substantially identical tips, the back having external and internal lateral surfaces, wherein each of said tips is wider than the back and has a sharpened end thereon, wherein said cores are positioned with the tips of one of said cores towards the tips of another one of said cores, such that an air gap exists therebetween, and wherein said stator assembly further includes non-magnetic conductive screens covering said external and internal lateral surfaces of the back of each core; wherein said levitator assembly includes four permanent magnets connected by rigid ties and positioned in two levels with two permanent magnets of the same polarity in each level, respective permanent magnets in said two levels positioned one under another being of opposite polarity, the permanent magnets having substantially identical rectangular cross-section with a middle point thereof, wherein a distance between the sharpened ends of the tips of each core is substantially equal to a distance between middle points of the permanent magnets positioned in each of said two levels, and wherein said permanent magnets are disposed in the air gap existing between the tips of the cores of the stator assembly; wherein said levitator assembly has an equilibrium position in which the permanent magnets in each of said two levels are situated centrally in the air gap between respective tips of the opposite cores and with the middle points of the permanent magnets in precise registration with the sharpened end of a respective one of said tips of the cores of the stator assembly; wherein said permanent magnets of the levitator assembly generate an original magnetic field and magnetize the steel cores of the stator assembly which in turn create a secondary magnetic field; and wherein, once said levitator assembly has been displaced from the equilibrium position, the original and the secondary magnetic fields create a stabilizing force returning the levitator assembly to the equilibrium position.

The objective of this invention is to simplify and provide a versatile device capable of accurately measuring seismic activity. The technique is based on magnetic levitation . The concept of magnetic levitation has been around since the 1960's, and it has been used extensively for high speed trains , however its use in seismology has been described in U.S. Pat No. 3,626,364 issued to Simon et al. However the present invention utilizes a four-vector magnetic field instead of three separate scalar magnetic fields. The advantages of present approach is reduction of three seismic masses to a single seismic mass. To detect seismic activity using this concept, a seismic mass must be magnetically suspended. A seismic mass trapped in a magnetic field still possesses its inertia. Therefore, as the magnetic field moves under the influence of seismic activity, the seismic mass will tend to stay in the same place. The controller, however tends to keep the seismic mass in its place. Consequently, the total current in the electromagnets increases to compensate for the seismic action in the z direction. To detect lateral motion, the current in two opposing electromagnetic is subtracted. A secondary way to detect seismic activity is accomplished through the measurement of the position of the seismic mass. This technique is also applicable in measuring acceleration in multiple axis, vibration, detection, and motion detection, exoatmospheric altitude determination and attitude determination in two axis of x and y.
EXEMPLARY CLAIMS- Claim- 1. A multi-axis magnetic suspension seismometer, comprising: a. A magnetically shielded support structure, b.

Subterranean tunnels extend deep into the Earth's crust between two points on the Earth's surface. A magnetically levitated rail transportation system operates in each tunnel. Gravity provides most of the energy needed to propel the trains . One or more magnetic accelerators in the tunnel provide the energy boost needed to compensate for frictional energy losses. Steam turbine-powered generators, disposed in the tunnels, provide electrical power to the magnetic levitation system and accelerators. The heat from the surrounding rock may be used to produce steam for powering the turbines. A machine for constructing the tunnels bores through solid rock and molten or partially molten rock. As the machine moves forward, it lays pipes that are fed from the surface through the newly-bored tunnel. The pipes carry chiller fluid that solidifies magma that comes into contact with the pipes. As a result, the machine bores through molten or partially molten rock and leaves a tunnel having hardened rock walls behind it as it moves. The chiller fluid is continuously pumped through the pipes from one end of the tunnel to the other, not only to maintain the tunnel walls in a solidified state but also to provide steam for powering the turbines.
EXEMPLARY CLAIMS- Claim- 1. A transportation system comprising: at least one subterranean tunnel; said tunnel having walls and a plurality of fluid-carrying pipes embedded in said walls for receiving heat from said walls; a rail extending through said tunnel for guiding a train thereon; and a propulsion system for converting said heat into electrical power sufficient to propel said train through said tunnel.

A positioning apparatus for a maglev vehicle includes multiple vehicle magnets. The magnets are paired For a suspension configuration, the magnets are one above the other, with a plurality of pairs arranged along the length of the vehicle . The poles are of adjacent magnets are opposite each other, transverse of the guideway. The guideway carries a conductor that is located symmetrically with respect to the two vehicle magnets. Among other things, the conductor may be a ladder, discrete coils or a helical winding. As the vehicle moves along the guideway, the voltages are induced in the circuits of the guideway conductor by the moving vehicle magnetic fields. If the vehicle is at a symmetry position with respect to the guideway, no current is induced in the guideway conductors because the magnetic fields from the pair of magnets cancel each other. However, if, as is typical, the vehicle is away from the symmetry position, such is the case due to the force of gravity, a current is induced that interacts with the vehicle magnets, to tend to push the vehicle toward the symmetry position. Thus, the vehicle is supported against gravity. The invention may also be used in a guidance configuration, by rotating the above described structure 90 degrees , so that the magnet poles are aligned vertically.
EXEMPLARY CLAIMS- Claim- 1. An apparatus for positioning a ground vehicle that travels along a guideway at a preselected position relative to the guideway, orthogonal axes designated "vertical"and "transverse"and a horizontal plane being defined relative to said guideway, said apparatus comprising: a. carried by said vehicle , a first means for generating a first vehicle magnetic field, having its poles aligned transverse of the guideway; b. carried by said vehicle , a second means for generating a magnetic field, adjacent to and vertically above said first magnetic field means, having its poles aligned parallel to and opposite to said poles of said first magnetic field means; and c. fixed to said guideway, passive, electrically conductive means, having a plurality of conductive loops, for Generating a guideway magnetic field to interact with said first and second vehicle magnetic fields to maintain said vehicle at said preselected position; whereby said first and second vehicle magnetic field means are on opposite sides of a horizontal vehicle plane of symmetry.

A side-wall beam is installed on a base for a guideway for a magnetic levitation vehicle . An elastic body is interposed between the side-wall beam and the base. Then, the side-wall beam is fastened to the base with a tendon on an imaginary line which extends through an intermediate portion of the elastic body in the transverse direction of the side-wall beam and which extends along the longitudinal direction of the side-wall beam. The elastic body is thereby held under compression between the side-wall beam and the base. The side-wall beam is supported on the base through the elastic body, and also fastened to the base, holding the elastic body under compression between the side-wall beam and the base. Reactive forces produced by the compression of the elastic body act to resist forces tending to cause the side-wall beam to fall over. Any displacement of the side-wall beam which may be caused by forces generated when the magnetic levitation vehicle passes can thereby be kept within a predetermined range.

A track vehicle such as a Maglev train has a body with superconducting coils mounted thereon which superconducting coils interact with vertically extending coils on guideways of a track to generate a propulsive force. The vehicle runs on wheels at low speeds but at higher speeds the superconducting coils may interact with ground coils to generate a lifting force. In order to reduce or eliminate stresses between the superconducting coils and the vehicle body, the vehicle has one or more wings of airfoil shape which generate lift. That lift may be sufficient to support the whole of the weight of the vehicle , enabling the ground coils to be eliminated. Furthermore, the shape of the superconducting coils may be changed so that they supply more energy to propulsive effects. Preferably the angle of incidence of the wing(s) is variable, to permit the lift generated thereby to be varied. This variation in the angle of incidence may be controlled by a sensor detecting the height of the body above the track, to maintain that height constant.
EXEMPLARY CLAIMS- Claim- 1. A vehicle arranged for movement on a track, said vehicle comprising: a body; at least one superconducting coil on said body for generating a propulsive force for said vehicle relative to said track; and quenching preventing means for preventing quenching of said at least one superconducting coil due to a whole weight of said vehicle being applied thereto, said quenching preventing means including at least one wing of airfoil shape on said body for generating a lifting force for supporting the whole weight of said vehicle , thereby causing said vehicle to float.

An expansion joint that allows a guideway of a magnetic levitation transportation system to expand and contract while minimizing transients occurring in the magnetic lift and drag forces acting on a magnetic levitation vehicle traveling over the joint includes an upper cut or recess extending downwardly from the upper surface of the guideway and a non-intersecting lower cut or recess that extends upwardly from the lower surface of the guideway. The sidewalls of the cuts can be parallel to each other and the vertical axis of the guideway; the depth of the lower cut can be greater than the depth of the upper cut; and the overall combined lengths of the cuts can be greater than the thickness of the guideway from the upper to lower surface so that the cuts will overlap, but be spaced apart from each other. The distance between the cuts can be determined on the basis of the force transients and the mechanical behavior of the guideway. A second pair of similarly configured upper and lower cuts may be disposed in the guideway; the expansion joint may consist of two upper cuts and one lower cut; or the cuts may have non-parallel, diverging sidewalls so that the cuts have a substantially dove-tail shape.
EXEMPLARY CLAIMS- Claim- 6.

A method for controlling a magnetic suspension vehicle which is guided by means of lenitation and guidance magnets ( magnetic wheels) along a track by means of individual magnet controls for each magnetic wheel. The controller signals (U sub R) or at least portions (U sub Su) of these signals are stochastically falsified for the individual magnet controls during standstill suspension or at low travel velocities of the magnetic suspension vehicle independently of each other. Thereby, the central interference possibilities of the track to the system vehicle/track are decentralized and asynchronized, so that all controls act independently of each other and the magnetic suspension vehicle or the dynamic overall system can be kept stable also at standstill and at low travel velocities.
EXEMPLARY CLAIMS- Claim- 1. A method for controlling a magnetic suspension vehicle which is guided by a plurality of levitation and guidance magnet means along a track, individual magnet control means being provided for each magnet means responsive to a plurality of control signals, the method comprising the step of stochastically falsifying at least one of the control signals or at least a portion of one of the control signals for each of the individual magnet control means independently of the control signals for others of the individual magnet control means during suspension of the magnetic suspension vehicle at standstill or at low travel velocities.

This invention uses magnetic levitation in combination with magnetic propulsion (MAGLEV) to accelerate an aircraft of spacecraft-or both crafts as a coupled unit-from standstill along a guideway to the highest possible launch velocity. The acceleration along the guideway is fuel efficient. The craft(s) are brought to launch velocity without using on board fuel. The computer controlled acceleration along the guideway could avoid high g forces to prevent damage to fragile payloads. The guideway may be sectionalized and of any shape. One section, for instance, may be circular to permit a long magnetically accelerated run with a relatively short length guideway. Very heavy crafts and payloads can be launched with superconducting levitation magnets in the guideway which form strong repulsive force fields with superconducting magnets in the MAGLEV vehicle . In another embodiment, the invention includes attraction magnets for the levitation . The invention could operate in an airless environment, such as the moon, to launch rocket powered spacecraft with their payloads. On earth, the invention could launch a rocket powered spacecraft coupled to an aircraft having air breathing engines. The aircraft would power the spacecraft to a staging altitude, where the spacecraft would actuate its own rocket engines for propulsion beyond the atmosphere, and separate from the aircraft. Unlike the space shuttle, all major components of the invention's space launch would be recovered for reuse. The invention may be multipurpose for serving to efficiently launch conventional aircraft. With a circular guideway, takeoff is inherently omnidirectional to take advantage of launch conditions.
EXEMPLARY CLAIMS- Claim- 1. An apparatus for launching a vehicle , the combination comprising: ; a guideway, the guideway including a curve along at least a portion of its length; ; a load, the load comprising a first vehicle and at least one additional vehicle ; ; a magnetic force field between the first vehicle and the guideway for propulsion of the load along the guideway, the propulsion including an acceleration of the load; ; a relatively shallow bank of the guideway along the curve toward the inside thereof for providing centripetal force to the load at lower velocities; ; a releasable engagement between the first vehicle and the additional vehicle , the engagement permitting a variable tilt therebetween; the tilt restricted essentially toward the inside of the curve transverse to a tangent thereof during at least a part of the propulsion; ; the additional vehicle characterized by aerodynamic lift surfaces thereupon; and ; the tilt of the additional vehicle effecting centripetal force thereupon by the aerodynamic lift at higher velocities wherein the load is accelerated to a velocity for releasing the engagement to launch the additional vehicle .

An improvement in an inductive repulsion type vehicle magnetic levitation and guide system for a curved track in which the vehicle is levitated by an electromagnetic force generated between levitation conductors having the same time constant and laid in two parallel rows on the ground at specific intervals in the direction of travel of the vehicle and levitation superconductive magnets on the vehicle capable of being electromagnetically coupled with the levitation conductors, the magnets being opposed to the levitation conductors at a specific distance from the levitation conductors. The vehicle is guided by an electromagnetic force generated between guide conductors having the same time constant successively positioned at specific intervals in the direction of travel of the vehicle and guide superconductive magnets mounted on the vehicle opposed to the guide conductors at a specific distance from the guide conductors. The electromagnetic force generated between the levitation superconductive magnets and the levitation conductors or between the guide superconductive magnet and the guide conductor on one side of a curved track is made larger than the similar force generated on the other side of the curved tracks, and the differential force counteracts the centrifugal force acting on the vehicle running over the curved track, thus stabilizing the vehicle running at high speed along the curved track.
EXEMPLARY CLAIMS- Claim- 1. An inductive repulsion type magnetic vehicle levitation and guide system, comprising: two parallel rows of levitation conductors having a predetermined time constant with said conductors being at specific intervals along a track in the direction of travel of the vehicle ; levitation superconductive magnets mounted on the vehicle in spaced opposed relation to said conductors and electromagnetically coupled with said conductors for levitating the vehicle by the electromagnetic force developed between said conductors and said magnets; guide means extending along the track in the direction of travel of the vehicle ; guide conductors having a predetermined time constant and positioned in parallel on said guide means in the direction of travel of the vehicle ; corresponding guide superconductive magnets mounted on the vehicle in spaced opposed relation to said guide conductors, said levitation magnets and levitation conductors and guide magnets and the guide conductors along a curved portion of the track being electromagnetically related for producing an electromagnetic repulsive force between at least one magnet and one conductor which is different from the electromagnetic repulsive force between the corresponding magnets and the corresponding conductors on the straight portion of the track and which is in a direction for counteracting the centrifugal force acting on the vehicle passing through the curved portion of the track.

In an induced repulsion type magnetic suspension system for a railway vehicle , superconductive magnets of opposite polarities are alternately set at specific intervals in the longitudinal direction of vehicle , while in the longitudinal direction of the track conductive loop coils or conductive sheets are continuously set at specific intervals, whereby the repulsion due to the eddy current caused by a voltage induced in said conductive loop coils or conductive sheets by the superconductive magnets and said superconductive magnets levitates the vehicle . In this invention, an additional source to produce a magnetic field of the same polarity is provided on the vehicle ; and thereby a magnetic flux with the same period as the vehicle vibration is applied which intersects said conductive loop coils or conductive sheets on the ground when the vehicle vibrates. Thus an induced current is produced by the magnetic flux and, using the magnetic force developed by this induced current and the magnetic source of the same polarity, the vibration of the running vehicle can be damped.
EXEMPLARY CLAIMS- Claim- 1. Vehicle vibration damping means for an induced repulsion type magnetic levitation system for railway vehicles , said system having superconductive levitating magnets with alternate opposite polarity positioned at specific intervals longitudinally of the vehicle and conductive loop coils or conductive sheets on the track at specific intervals in the direction of travel of the vehicle , and the vehicle is levitated by the repulsion taking place due to said superconductive magnets and the eddy currents produced by the voltage induced in said loop coils by the flux from said magnets when the vehicle runs at a specified speed, said vibration damping means comprising means on the vehicle for constantly applying a magnetic flux in one direction and of a specific magnitude to said conductive loop coils from the vehicle , said flux being in addition to the levitation flux, for producing a damping magnetic force on said vehicle as a result of the current induced in the conductive loop coils or conductive sheets by said additional magnetic flux for damping the vibrations of the vehicle.

A SYSTEM THAT INCLUDES AN ELONGATE CYLINDRICAL VEHICLE OPERABLE TO TRAVEL ALONG A SIMILARLY-SHAPED, TROUGH-LIKE GUIDEWAY. AT STATIONS ALONG THE GUIDEWAY, THE VEHICLE IS SUPPORTED BY WHEELS, BUT BETWEEN STATIONS IT LEVITATES AT ABOUT 25 CENTIMETERS ABOVE THE INSIDE GUIDEWAY SURFACE. LEVITATION OF THE MOVING VEHICLE IS EFFECTED BY INTERACTION BETWEEN MAGNETIC DIPOLE FIELDS PROVIDED BY SUPERCONDUCTING COILS OR PERMANENT MAGNETS DISPOSED OVER SUBSTANTIALLY THE WHOLE LOWER SURFACE AREA OF THE VEHICLE AND A PAIR OF SPACED CONDUCTING STRIPS LOCATED ON THE GUIDEWAY INNER SURFACE AND ORIENTED PARALLEL TO THE LONGITUDINAL AXIS OF THE GUIDEWAY THROUGHOUT ITS LENGTH. THE VEHICLE IS FREE TO ROTATE OR PIVOT ABOUT ITS LONGITUDINAL AXIS AND THIS, COUPLED WITH THE VERY RESILIENT SUPPORT OVER ITS ENTIRE LENGTH, PERMITS IT TO TRAVEL AT 200 KILOMETERS PER HOUR AND BEYOND WITH MINIMUM DISCOMFORT TO PASSENGERS BEING TRANSPORTED. THE MAGNETIC DIPOLE FIELDS MUST BE OF THE ORDER OF 1,000 TO 3,000 GAUSS AT A DISTANCE OF 25 CENTIMETERS FROM THE VEHICLE TO GIVE THE SUPPORT NECESSARY TO MAINTAIN THE 25 CENTIMETER CLEARANCE. THE NECESSARY PROPELLING FORCE IS SUPPLIED BY A POLYPHASE WINDING WHICH IS DISPOSED IN THE LOWER PORTION OF THE GUIDEWAY BETWEEN THE CONDUCTING STRIPS; THE WINDING PRODUCES A TRAVELING-WAVE MAGNETIC FIELD THAT INTERACTS WITH THE MAGNETIC DIPOLE FIELDS. BETWEEN STATIONS SYNCHRONOUS OPERATION IS ACCOMPLISHED BY EMPLOYING A.C. POWER INPUT WITH A CYCLOCONVERTER, I.E., AN A-C TO A-C CONVERTER, TO REDUCE THE INPUT FREQUENCY TO AN APPROPRIATE RATIO. ACCELERATION AND DECELERATION OF THE VEHICLE IS ACCOMPLISHED BY VARYING THE FREQUENCY OF THE CYCLOCONVERTER TO PROVIDE SYNCHRONOUS INTERACTION BETWEEN THE MAGNETIC FIELD OF THE WINDING AND THE MAGNETIC DIPOLE FIELDS OF THE SUPERCONDUCTING COILS AS THE VEHICLE ACCELERATES. PROVISION IS MADE FOR SWITCHING VEHICLES , AND A NOVEL METHOD OF GUIDEWAY FABRICATION IS DISCLOSED.

A SYSTEM THAT INCLUDES AN ELONGATE CYLINDRICAL VEHICLE OPERABLE TO TRAVEL ALONG A SIMILARLY-SHAPED, TROUGH-LIKE GUIDE-WAY. AT STATIONS ALONG THE GUIDEWAY, THE VEHICLE IS SUPPORTED BY WHEELS, BUT BETWEEN STATIONS IT LEVITATES AT ABOUT 25 CENTIMETERS ABOVE THE INSIDE GUIDEWAY SURFACE. LEVITATION OF THE MOVING VEHICLE IS EFFECTED BY INTERACTION BETWEEN MAGNETIC DIPOLE FIELDS PROVIDED BY SUPERCONDUCTING COILS OR PERMANENT MAGNETS DISPOSED OVER SUBSTANTIALLY THE WHOLE LOWER SURFACE AREA OF THE VEHICLE AND A PAIR OF SPACED CONDUCTING STRIPS LOCATED ON THE GUIDEWAY INNER SURFACE AND ORIENTED PARALLEL TO THE LONGITUDINAL AXIS OF THE GUIDEWAY THROUGHOUT ITS LENGTH. THE VEHICLE IS FREE TO ROTATE OR PIVOT ABOUT ITS LONGITUDINAL AXIS AND THIS, COUPLED WITH THE VERY RESILIENT SUPPORT OVER ITS ENTIRE LENGTH, PERMITS IT TO TRAVEL AT 200 KILOMETERS PER HOUR AND BEYOND WITH MINIMUM DISCOMFORT TO PASSENGERS BEING TRANSPORTED. THE MAGNET DIPOLE FIELDS MUST BE OF THE ORDER OF 1,000 TO 3,000 GAUSS AT A DISTANCE OF 25 CENTIMETERS FROM THE VEHICLE TO GIVE THE SUPPORT NECESSARY TO MAINTAIN THE 25 CENTIMETER CLEARANCE. THE NECESSARY PROPELLING FORCE IS SUPPLIED BY A POLYPHASE WINDING WHICH IS DISPOSED IN THE LOWER PORTION OF THE GUIDEWAY BETWEEN THE CONDUCTING STRIPS; THE WINDING PRODUCES A TRAVELING-WAVE MAGNETIC FIELD THAT INTERACTS WITH THE MAGNETIC DIPOLE FIELDS. BETWEEN STATIONS SYNCHRONOUS OPERATION IS ACCOMPLISHED BY EMPLOYING A.C. POWER INPUT WITH A CYCLOCONVERTER, I.E., AN A-C TO A-C CONVERTER, TO REDUCE THE INPUT FREQUENCY TO AN APPROPRIATE RATIO. ACCELERATION AND DECELERATION OF THE VEHICLE IS ACCOMPLISHED BY VARYING THE FREQUENCY OF THE CYCLOCONVERTER TO PROVIDE SYNCHRONOUS INTERACTION BETWEEN THE MAGNETIC FIELD OF THE WINDING AND THE MAGNETIC DIPOLE FIELDS OF THE SUPERCONDUCTING COILS AS THE VEHICLE ACCELERATES. PROVISION IS MADE FOR SWITCHING VEHICLES , AND A NOVEL METHOD OF GUIDEWAY FABRICATION IS DISCLOSED.

One or more magnetic levitation vehicles are provided to transport a storage mass over a magnetic levitation guideway extending between an elevated upper end and a lower end at a lower elevation, and including a plurality of magnetic propulsion windings. Movement of a magnetic levitation vehicle with the storage mass along the magnetic levitation guideway from the elevated upper end to the lower end generates electrical energy through the propulsion windings of the magnetic levitation guideway. The magnetic levitation vehicle with a storage mass can be propelled from the lower end to the upper end of the magnetic levitation guideway, where the storage mass is unloaded to store gravitational potential energy. The magnetic levitation vehicle and storage mass can then be moved to the lower end of the magnetic levitation guideway to convert the stored gravitational potential energy to electrical power. The magnetic levitation guideway can be an inclined guideway or a vertically oriented guideway, can be a surface guideway, can be disposed in a sub-surface tunnel, or can be a combination of a surface guideway and a sub-surface tunnel.

The invention relates to an arrangement for the non-contact production of magnetic lateral. forces used to guide a magnetic levitation railway train . Said arrangement comprises. an upper C-shaped ferromagnetic track having two downward-pointing ends. (2, 3), and an excitation element which is located on the vehicle side below. the upper track. The excitation element comprises a guiding magnet device. (5, 6) which has at least two excitation poles (5, 6) lying opposite the ends (2,. 3) of the track, a connecting yoke which connects the excitation pole, and. a coil device (8, 9). The aim of the invention is to reliably produce lateral forces. of a desired amplitude at a relatively low cost in terms of technical equipment, and. especially also to have compact excitation elements on the vehicle side. In order. to achieve this, a carrier magnet device which is arranged on the upper track . is connected to the excitation element to create a levitation force. A lateral. force can be produced by superposing a field eddy which is produced between the. guiding magnet device (5, 6) and the ends (2, 3) of the track, and a coil field which. is produced by means of the coil device (8, 9).

A transport system has a pair of levitating rails, and each of the levitating. rails has a core with a plurality of coils extending circumferentially. around each of the cores. The coils are perpendicular to the lengths. of the levitating rails. Each of the levitating rails has an upper surface directly above the core. A vehicle has wheels that roll on the upper. surfaces of the levitating rails in a nonlevitating position. The vehicle . has a plurality of magnets that create magnetic fields that pass through. the coils while the vehicle is moving along the levitating rails.. The magnetic fields induce current, which in turn causes an opposing magnetic field that levitates the vehicle . A steering rail having a plurality of coils is mounted to at least one of the guideways. Permanent steering magnets are located on each side of the steering rail to magnetically steer the. vehicle along the guideways.

A new method is described to produce directional currents in the space lattice, the fundamental fabric of the universe. The currents may be unidirectional or vortexual in nature and are suitable for propulsion or the generation of electric power. For propulsion, the unidirectional currents are induced by charging capacitors possessing suitable geometries. This will allow the manufacture of vehicles capable of levitation and flight. The vortexual space lattice currents are produced in a suitable pyramid when electrostatic and magnetic fields interact transversally. The vortex causes charge separation and current in the coil wrapped around the pyramid.

The magnetic levitation system for long distance delivery of water includes a magnetic levitation guideway and a magnetic levitation train of vehicles for carrying large amounts of water at high speed. Vehicles of the water train have a large, flexible balloon having a thick skin formed of reinforced flexible composite material for carrying water. When pressurized and filled with water, the container forms a streamlined cylinder that runs the full length of the vehicle . After delivery of the water load and depressurization, the flexible skins are depressurized and collapsed to minimize the frontal area and air drag on the vehicles . An "iron lift" guideway panel provides the magnetic lift force, with superconducting magnets on the vehicle attracted upwards to laminated steel plates attached to the guideway. Null flux aluminum loops provide for inherent stabilization. Unstable horizontal attractive forces are countered by null flux stability loop circuits making the stable restoring force from the null flux loops greater than the unstable force from the attraction to the steel plates, so that the net horizontal force is restoring, and the suspension is horizontally stable.

The invention relates to a line-changing device for the tracks of a magnetic levitation train . The tracks are formed by track supports arranged one after the other and can be connected with each other. To connect the tracks a track support configured as a bendable support is positioned along each track which can be bent to establish a connection between the tracks. In its bent state each bendable support can be positioned in relation to the other bendable support. Along each track a connecting support is arranged next to the bendable support, which connecting support can be moved out of the clearance gauge of the train so as to create a distance required for the train to pass across the rail joint embodied by the bendable supports. The invention consists of the fact that the connecting supports can be bent so as to form a second rail joint and that the bendable supports can be moved out of the clearance gauge of the train when the rail joint is established by means of the connecting supports.

The invention relates to a line-changing device for the tracks (1, 2) of a magnetic levitation train . The tracks (1, 2) are formed by track supports arranged one after the other and the lines are changed by means of a rail joint between the tracks (1, 2). To connect the tracks a track support configured as a bendable support is positioned along each track which bendable support can be bent to establish a connection between the tracks (1, 2). In its bent state each bendable support can be positioned in relation to the other bendable support. Along each track (1, 2) a track support situated next to the bendable support is configured as a connecting support, which when the rail joint is established can be moved out of the clearance gauge of the train . The invention consists in the fact that the connecting supports can be moved without deformation.
