Transistor a. c. gate circuit

Claim 1

A GATING SYSTEM IN WHICH THE SIGNAL TO BE GATED IS UTILIZED TO CAUSE THE GATE TO BE TURNED ON AND OFF COMPRISING: A BISTABLE MULTIVIBRATOR HAVING AN INPUT AND A PAIR OF OUTPUTS; MEANS FOR SAMPLING A PORTION OF SAID SIGNAL HAVING A PAIR OF OUTPUTS AND A PAIR OF INPUTS, EACH OF SAID INPUTS CONNECTED TO A RESPECTIVE OUTPUT OF SAID BISTABLE MULTIVIBRATOR: A GATE TRANSISTOR HAVING AN INPUT ELECTRODE AND AN OUTPUT ELECTRODE; A CAPACITOR CONNECTED BETWEEN ONE OF THE OUTPUTS OF SAID MULTIVIBRATOR AND THE INPUT ELECTRODE OF SAID GATE TRANSISTOR; A RECTIFYING NETWORK HAVING ITS INPUTS CONNECTED TO THE OUTPUTS OF SAID SAMPLING MEANS; AND AN INTEGRATING MEANS; THE OUTPUT OF SAID RECTIFTING NETWORK CONNECTED TO SAID INTEGRATING MEANS AND A SECOND TRANSISTOR HAVING A BASE ELECTRODE, EMITTER ELECTRODE AND A COLLECTOR ELECTRODE, THE EMITTER ELECTRODE OF SAID SECOND TRANSISTOR CONNECTED TO ONE END OF SAID CAPACITOR AND SAID COLLECTOR ELECTRODE OF SAID SECOND TRANSISTOR CONNECTED TO THE OTHER END OF SAID CAPACITOR, SAID BASE ELECTRODE OF SAID SECOND TRANSISTOR CONNECTED TO SAID INTEGRATING MEANS WHEREBY SIGNALS ARE GATED TO THE OUTPUT ELECTRODE OF SAID GATE TRANSISTOR IN RESPONSE TO A CONTROL SIGNAL DEVELOPED BY SAID INTEGRATING MEANS.
