Electrical superconductive switches

Claim 1

AN ELECTRICAL SWITCH INCLUDING A SUPERCONDUCTOR SWITCHING ELEMENT HAVING A PLURALITY OF LAYERS OF A SUPERCONDUCTING MATERIAL WHICH HAS A TRANSITION TEMPERATURE, A SUPERCONDUCTIVE STATE, AND A NORMAL STATE, SAID LAYERS BEING CONNECTED ELECTRICALLY IN SERIES, A PLURALITY OF LAYERS OF INSULATING MATERIAL BETWEEN SAID LAYERS OF SUPERCONDUCTING MATERIAL TO INSULATE SAID LAYERS OF SUPERCONDUCTING MATERIAL FROM ONE ANOTHER, A PAIR OF TERMINALS CONNECTED TO SAID SUPERCONDUCTOR SWITCHING ELEMENT, REFRIGERATION MEANS NORMALLY TO MAINTAIN SAID SUPERCONDUCTING MATERIAL BELOW ITS TRANSITION TEMPERATURE, A PLURALITY OF CONTROL WINDINGS, EACH CONTROL WINDING BEING ADJACENT TO A SAID LAYER OF SUPERCONDUCTING MATERIAL, MEANS INSULATING EACH CONTROL WINDING FROM THE ADJACENT LAYER OF SUPERCONDUCTING MATERIAL, PULSE TRANSFORMER MEANS HAVING PRIMARY WINDING MEANS AND A PLURALITY OF SECONDARY WINDING MEANS, EACH SAID SECONDARY WINDING MEANS BEING CONNECTED TO A SAID CONTROL WINDING, AND A PULSING DEVICE CONNECTED TO SAID PRIMARY WINDING MEANS TO SUPPLY A PULSE OF CURRENT THERETO, SO AS SIMULTANEOUSLY TO ENERGIZE EACH OF SAID PLURALITY OF SECONDARY WINDING MEANS, WHEREBY WHEN SAID PRIMARY WINDING IS NOT ENERGIZED, SAID PLURALITY OF CONTROL WINDINGS IS NOT ENERGIZED, AND SAID SUPERCONDUCTING MATERIAL CONNECTED TO SAID TERMINAL IS IN SAID SUPERCONDUCTIVE STATE, AND WHEREBY WHEN SAID PRIMARY WINDING IS ENERGIZED BY A SAID PULSE OF CURRENT, SAID PLURALITY OF CONTROL WINDINGS IS ENERGIZED, AND SAID SUPERCONDUCTING MATERIAL CONNECTED TO SAID TERMINALS ADOPTS SAID NORMAL STATE.
