Gated amplifier circuits

Claim 1

A GATED AMPLIFIER COMPRISING PUSH-PULL INPUT CIRCUIT MEANS AND PUSH-PULL OUTPUT CIRCUIT MEANS, A FIRST AND A SECOND PAIR OF SIGNAL TRANSLATION VALVE MEANS CAPABLE OF BEING CONTROLLED FOR CURRENT-CONDUCTING AND NON-CONDUCTING CONDITIONS, HEREINAFTER REFERRED TO, RESPECTIVELY, AS "ON" AND "OFF" CONDITIONS, SAID FIRST PAIR OF VALVE MEANS BEING CONNECTED WITH THEIR CURRENT CONDUCTING PATHS IN SHUNT ACROSS SAID PUSH-PULL INPUT MEANS AND SAID SECOND PAIR VALVE MEANS BEING CONNECTED WITH THEIR CURRENT CONDUCTING PATHS IN SERIES WITH SAID PUSHPULL INPUT AND OUTPUT MEANS, SAID SECOND PAIR OF VALVE MEANS BEING NORMALLY IN THE "ON" CONDITION, CIRCUIT MEANS INCLUDING GATING SIGNAL MEANS FOR APPLYING GATING SIGNALS TO SAID FIRST AND SECOND PAIRS OF VALVE MEANS FOR SIMULTANEOUSLY RENDERING SAID SECOND PAIR OF VALVE MEANS "OFF" AT THE SAME TIME THAT SAID FIRST PAIR OF VALVE MEANS IS RENDERED "ON," WHEREBY THE CONDUCTING IMPEDANCE OF SAID FIRST PAIR OF VALVE MEANS IS PLACED ACROSS SAID PUSH-PULL INPUT MEANS WHEN SAID SECOND PAIR OF VALVE MEANS ARE IN THE "ON" CONDITION, THUS MAINTAINING SUBSTANTIALLY CONSTANT IMPEDANCE TO THE INPUT CIRCUIT AND ELIMINATING TRANSIENTS IN THE OUTPUT CIRCUIT MEANS.
