Gate circuit which uses the output signal to control bias of an input trigger circuit

Claim 1

A CIRCUIT ADAPTED TO APPLY AND REMOVE POWER FROM A CONTROLLABLE DEVICE COMPRISING THRESHOLD MEANS, A SCHMITT TRIGGER CIRCUIT HAVING A NORMALLY CONDUCTING SECTION AND A NORMALLY NONCONDUCTING SECTION, THE OUTPUT SIGNAL FROM THE NORMALLY CONDUCTING SECTION BEING APPLIED TO SAID THRESHOLD MEANS BUT BEING NORMALLY INSUFFICIENT TO CAUSE THAT MEANS TO PROVIDE AN OUTPUT SIGNAL, SAID NORMALLY NONCONDUCTING SECTION BEING ADAPTED TO HAVE APPLIED THERETO A CONTROL SIGNAL WHICH WHEN OF A PARTICULAR FIRST PREDETERMINED LEVEL CAUSES SAID NORMALLY NONCONDUCTING SECTION TO CONDUCT AND SAID NORMALLY NONCONDUCTING SECTION TO CEASE CONDUCTING, WHEREBY THE OUTPUT SIGNAL FROM SAID NORMALLY CONDUCTING SECTION RISES RAPIDLY TO A POINT SUFFICIENT TO CAUSE THE THRESHOLD MEANS TO PROVIDE AN OUTPUT SIGNAL, GATE MEANS RESPONSIVE TO THE OUTPUT SIGNAL FROM SAID THRESHOLD MEANS TO PASS POWER THERETHROUGH, AND MEANS RESPONSIVE TO THE POWER THAT PASSES THROUGH SAID GATE MEANS TO PROVIDE A BIAS SIGNAL, SAID SIGNAL BEING APPLIED TO SAID NORMALLY NONCONDUCTING SECTION TO LOWER THE CONTROL SIGNAL LEVEL FOR WHICH IT CONDUCTS.
