Abstract
Abstract A superconductive element switch having a first winding which assumes an annular form capable of passing from a superconductive state to a conductor state by application of a pulse of an intense magnetic field. This pulse is applied through a second control winding. Electrical power can be stored to a high degree within the superconductive element and then restored in an extremely fast responsive time, by changing the state of the first winding from a superconductive to a conductor state.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A superconductive element switch having a ring like configuration for storing electrical energy and releasing it in a relatively short time span comprising a first winding of superconductive cable, the cable being wound into layers of turns with the layers extending in the radial direction, one end of the superconductive cable being one terminal of the switch, while the other end is the other terminal; a second winding of control cable having turns of cable wound within a radial plane of the ring so as to envelop the first winding and having for its surface that of the cross-section of the ring by an axial half-plane; a first insulation material separating the turns of the first winding; a second insulating material covering and supporting the first winding and first insulation material, and a third insulating housing enveloping the first winding and first and second insulating material, whereby the second winding can control the release of electrical energy.
Claim 2
Dependent Claim
157 words
