High speed alternating current fault sensing circuit

Claim 1

A HIGH SPEED ALERNATING CURRENT FAULT SENSING APPARATUS COMPRISING: MEANS FOR SENSING AN UNDER-VOLTAGE IN A SOURCE OF ALTERNATING CURRENT POWER INCLUDING, RECTIFYING MEANS COUPLED TO SAID SOURCE OF ALTERNATING CURRENT POWER FOR PROVIDING AN UNREGULATED DIRECT CURRENT VOLTAGE LEVEL, FIRST VOLTAGED DIVIDER MEANS COUPLED TO SAID UNREGULLATED VOLTAGE LEVEL FOR PROVIDING A REGULATED DIRECT CURRENT REFERENCE VOLTAGE, RESISTOR VOLTAGE DIVIDER MEANS COUPLED TO SAID UNREGULATED VOLTAGE LEVEL FOR PROVIDING AN UNREGULATED DIRECT CURRENT TEST VOLTAGE TO BE COMPARED WITH SAID REGULATED REFERENCE VOLTAGE, A FIRST TRANSISTOR HAVING ITS EMITTER COUPLED TO SAID REFERENCE VOLTAGE AND ITS BASE COUPLED TO SAID TEST VOLTAGE FOR PRODUCING AN OUTPUT ON ITS COLLECTOR WHENEVER THE MAGNITUDE OF SAID TEST VOLTAGE BECOMES LESS THAN THE MAGNITUDE OF SAID REFERENCE VOLTAGE, AND A SECOND TRANSISTOR CONNECTED TO A SEPARATE SOURCE OF DIRECT CURRENT AND COUPLED TO THE COLLECTOR OF SAID FIRST TRANSISTOR TO BE RESPONSIVELY ACTIVATED BY THE OUTPUT CURRENT PRODUCED IN THE COLLECTOR CIRCIT OF SAID FIRST TRANSISTOR AND PROVIDE UPON SAID SEPERATE ACTIVATION, A SECOND CURRENT FLOW FROM SAID SEPERATE SOURCE OF DIRECT CURRENT THROUGH THE COLLECTOR CIRCUIT OF SAID FIRST TRANSISTOR TO THEREBY RAPIDLY GENERATE A FAULT SIGNAL.
