Cryotron arrangement and cryotrons suitable for use in such arrangements

Claim 1

A CRYOTRON COMPRISING A CURRENT CONDUCTOR CONSTITUTED OF SUPER-CONDUCTIVE MATERIAL AND POSSESSING A STABLE NORMAL-CONDUCTIVE FIRST STATE AND A STABLE SUPERCONDUCTIVE SECOND STATE, MEANS FOR COOLING THE ENVIRONMENT OF SAID CURRENT CONDUCTOR TO A GIVEN AMBIENT TEMPERATURE, SAID GIVEN AMBIENT TEMPERATURE BEING NOT GREATER THAN THE EFFECTIVE TRANSITION TEMPERATURE OF SAID CURRENT CONDUCTOR, MEANS THERMALLY INSULATING SAID CURRENT CONDUCTOR FROM SAID ENVIRONMENT, MEANS FOR PASSING CURRENT THROUGH SAID CURRENT CONDUCTOR, AND MEANS FOR SELECTIVELY SWITCHING SAID CURRENT CONDUCTOR FROM ONE OF SAID FIRST AND SECOND STABLE CONDUCTIVE STATES TO THE OTHER OF SAID STABLE CONDUCTIVE STATES, SAID MEANS FOR SWITCHING COMPRISING FIRST MEANS FOR TEMPORARILY DECREASING SAID CURRENT PASSING THROUGH SAID CURRENT CONDUCTOR TO SWITCH SAID CURRENT CONDUCTOR FROM SAID FIRST STABLE CONDUCTIVE STATE TO SAID SECOND STABLE CONDUCTIVE STATE AND SECOND MEANS FOR TEMPORARILY INCREASING SAID CURRENT PASSING THROUGH SAID CURRENT CONDUCTOR TO SWITCH SAID CURRENT CONDUCTOR FROM SAID SECOND STABLE STATE TO SAID FIRST STABLE STATE, SAID CURRENT PASSING THROUGH SAID CURRENT CONDUCTOR WHEN SAID CURRENT CONDUCTOR IS SWITCHED TO SAID NORMALCONDUCTIVE STATE BEING SUFFICIENT TO PROVIDE A RESULTANT HEAT DISSIPATION TO MAINTAIN SAID CURRENT CONDUCTOR AT A TEMPERATURE ABOVE SAID GIVEN AMBIENT TEMPERATURE TO MAINTAIN SAID NORMAL-CONDUCTIVE STATE.
