Electrical protective circuit

Claim 1

AN ELECTRICAL PROTECTIVE CIRCUIT COMPRISING: (A) A MAIN CURRENT CONTROL DEVICE HAVING A FIRST CONDITION IN WHICH IT IS CONDUCTIVE INA FIRST DIRECTION AND A SECOND CONDITION IN WHICH IT IS SUBSTANTIALLY NON-CONDUCTIVE IN SAID FIRST DIRECTION, SAID DEVICE BEING CAPABLE OF BEING CHANGED FROM SAID FIRST CONDITION TO SAID SECOND CONDITION BY REDUCING CURRENT THERETHROUGH IN SAID FIRST DIRECTION TO ZERO FOR A PREDETERMINING TIME, (B) MEANS FOR CONNECTING SAID MAIN CURRENT CONTROL DEVICE ELECTRICALLY IN SERIES WITH A POWER CONSUMING LOAD ACROSS THE TERMINALS OF A POWER SOURCE, (C) ELECTRICAL CHARGE STORGE MEANS, (D) MEANS FOR CONNECTING SAID ELECTRICAL CHARGE STORAGE MEANS ELECTRICALLY IN PARALLEL WITH SAID CUTTER CONTROL DEVICE UPON THE OCCURRENCE OF PREDETERMINED ELECTRICAL CONDITIONS IN SAID LOAD CIRCUIT, THE POLARITY OF SAID CHARGE STORAGE MEANS BEING SUCH AS TO TEND TO CAUSE CURRENT FLOW THROUGH SAID CONTROL DEVICE IN A DIRECTION OPPOSITE TO SAID FIRST DIRECTION, WHEREBY THE CHARGE STORED BY SAID ELECTRICAL CHARGE STORAGE MEANS IS CAUSED TO DISCHARGE THROUGH A DISCHARGE PATH INCLUDING SAID ELECTRICAL POWER SOURCE AND SAID LOAD, (E) MEANS LIMITING THE RATE OF DISCHARGE OF SAID ELECTRICAL CHARGE STORAGE MEANS THROUGH A PATH INCLUDING SAID ELECTRICAL POWER SOURCE AND SAID LOAD, COMPRISING A CURRENT-LIMITING DEVICE CONNECTED ELECTRICALLY IN SERIES WITH SAID LOAD AND IN SAID DISCHARGE PATH OF SAID CHARGE STORAGE LOAD AND IN SAID DISCHARGE PATH (F) SAID CURRENT-LIMITING DEVICE HAVING A RELATIVELY RELARESISTANCE NORMALLY AND CHANGING SUDDENLY TO RELATIVELY HIGH RESISTANCE UPON THE OCCURRENCE OF PREDETERMINED CURRENT CONDITIONS THERETHROUGH WITHOUT PERMANENTLY INTERRUPTING CONDITIVITY THERETHROUGH.
