Abstract
Abstract An electromagnetic system for the guided suspension of a moving vehicle above a track or roadbed utilizing along each side of the vehicle pairs of opposed superconducting loops defining elongated tubular cavities therebetween, and a pair of arrays of independent elongated inductive suspension and guidance loops disposed in cruciform arrangement with the suspension loops generally horizontal and the guidance loops generally vertical, the cavities of the vehicle adapted to receive the respective arrays of loops during traverse of the vehicle along the roadbed, whereby the vehicle is suspended above the roadbed by the induced suspension field and guided along the roadbed by the induced guidance field.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
96 words
A magnet system for the guided suspension of a moving vehicle above a roadbed comprising two pairs of superconducting vehicle loops secured along respective sides of the vehicle in spaced parallel relation to one another in vertical disposition for producing a common magnetic field therebetween to generate a lifting force on the vehicle to counteract the force of gravity on the vehicle; and respective stabilization inductive track loops mounted on each side of the roadbed in vertical disposition between said vehicle loops for generating a horizontal guidance force on the vehicle simultaneously with the lifting force.
Claim 2
Dependent Claim
96 words
A magnet system for the guided suspension of a moving vehicle above a roadbed comprising two pairs of superconducting vehicle loops secured along respective sides of the vehicle in spaced parallel relation to one another in vertical disposition for producing a common magnetic field therebetween to generate a lifting force on the vehicle to counteract the force of gravity on the vehicle; and respective stabilization inductive track loops mounted on each side of the roadbed in vertical disposition between said vehicle loops for generating a horizontal guidance force on the vehicle simultaneously with the lifting force.
