Multi-layered cryogenic switching devices

Claim 1

A GATING DEVICE COMPRISING FIRST, SECOND AND THIRD CONDUCTORS DISPOSED IN PARALLEL SPACED RELATIONSHIP, SAID SECOND CONDUCTOR BEING ARRANGED WITHIN SAID FIRST CONDUCTOR, SAID THIRD CONDUCTOR BEING ARRANGED WITHIN SAID SECOND CONDUCTOR, SAID CONDUCTORS BEING FABRICATED OF SUPERCONDUCTOR MATERIAL AND MAINTAINED AT AN OPERATING TEMPERATURE AT WHICH EACH IS IN A SUPERCONDUCTIVE MATERIAL IN THE ABSENCE OF A MAGNETIC FIELD, INPUT MEANS FOR SAID DEVICE COMPRISING MEANS CONNECTED TO LONGITUDINALLY SPACED POINTS ON SAID THIRD CONDUCTOR FOR PRODUCING LONGITUDINAL CURRENT THEREIN AND THEREBY GENERATING A MAGNETIC FIELD IN THE VICINITY OF SAID FIRST CONDUCTOR, SAID MAGNETIC FIELD PRODUCED BY THE LONGITUDINAL CURRENT IN SAID THIRD CONDUCTOR BEING LESS THAN THE CRITICAL FIELD REQUIRED TO DRIVE SAID FIRST CONDUCTOR FROM A SUPERCONDUCTIVE TO A RESISTIVE STATE, OUTPUT CIRCUIT MEANS FOR SAID DEVICE CONNECTED TO LONGITUDINALLY SPACED POINTS ON SAID FIRST CONDUCTOR, FURTHER CIRCUIT MEANS CONNECTED TO LONGITUDINALLY SPACED POINTS ON SAID SECOND CONDUCTOR FOR CONTROLLING THE EFFECT OF SAID MAGNETIC FIELD PRODUCED BY SAID CURRENT IN SAID THIRD CONDUCTOR ON SAID FIRST CONDUCTOR, WHEREIN SAID FURTHER MEANS IS FABRICATED ENTIRELY OF SUPERCONDUCTIVE MATERIAL MAINTAINED AT A TEMPERATURE AT WHICH IT IS A SUPERCONDUCTIVE STATE IN THE ABSENCE OF A MAGNETIC FIELD AND FORMS WITH SAID SECOND CONDUCTOR A CLOSED SUPERCONDUCTIVE LOOP, AND WHEREIN THERE IS PROVIDED MEANS ARRANGED IN MAGNETIC FIELD APPLYING RELATIONSHIP TO A PORTION ONLY OF SAID FURTHER CIRCUIT MEANS FOR CONTROLLING THE STATE, SUPERCONDUCTIVE OR NORMAL, OF SAID PORTION ONLY AND WHEREBY CONTROLLING THE TRANSMISSION OF SIGNALS BETWEEN SAID FIRST AND THIRD CONDUCTORS.
