Protective circuits for superconductive loads

Claim 1

A PROTECTIVE CIRCUIT FOR A SUPERCONDUCTIVE LOAD ADAPTED TO BE CONNECTED TO A POWER SUPPLY AND ENERGIZED THEREBY COMPRISING: (A) A FIRST LOAD CURRENT SWITCHING MEANS; (B) MEANS CONNECTED TO SAID FIRST LOAD CURRENT SWITCHING MEANS TO INITIATE CONDUCTION THERETHROUGH; (C) MEANS CONNECTED TO SAID FIRST LOAD CURRENT SWITCHING MEANS TO TERMINATE CONDUCTION THERETHROUGH; (D) SENSING MEANS CONNECTED TO SAID CONDUCTION TERMINATION MEANS AND TO SAID SUPERCONDUCTIVE LOAD TO ACTUATE SAID CONDUCTION TERMINATION MEANS IN RESPONSE TO A SIGNAL DEVELOPED AT THE INCEPTION OF THE TRANSITION OF A PORTION OF SAID SUPERCONDUCTIVE LOAD TO A NORMAL STATE; (E) A SECOND LOAD CURRENT SWITCHING MEANS CONNECTED IN PARALLEL WITH SAID FIRST LOAD CURRENT SWITCHING MEANS; (F) MEANS CONNECTED TO SAID SECOND LOAD CURRENT SWITCHING MEANS TO INITIATE CONDUCTION THERETHROUGH A PREDETERMINED PERIOD AFTER CONDUCTION THROUGH SAID FIRST LOAD CURRENT SWITCHING MEANS HAS TERMINATED, SAID SECOND LOAD SWITCHING CONDUCTION INITIATION MEANS BEING CONNECTED TO AND RESPONSIVE TO SAID CONDUCTION TERMINATION MEANS; AND (G) ANCILLARY STORAGE MEANS TO MAINTAIN THE MAGNETIC FIELD AND ITS ENERGY DURING THE TIME IN WHICH THE CURRENT IN THE SUPERCONDUCTIVE LOAD IS INTERRUPTED AND SUPERCONDUCTIVITY IS BEING RESTORED; AND (H) ENERGY DISSIPATION MEANS TO DISSIPATE THE LEAKAGE ENERGY OF THE SUPERCONDUCTIVE LOAD AND TO REDUCE THE CURRENT IN THE SUPERCONDUCTIVE LOAD LOAD TO IDENTICALLY ZERO VALUE IN THE SHORTEST POSSIBLE TIME.
