Transistor inverter amplifier employing capacitor diode combination to provide synchronous output from synchronoulsy applied input

Claim 1

A PULSE GENERATING CIRCUIT COMPRISING AN INVERTING AMPLIFIER TRANSISTOR HAVING EMITTER, BASE AND COLLECTOR ELECTRODES, A SOURCE OF EMITTER POTENTIAL, SAID TRANSISTOR BEING NORMALLY BIASED OFF, A SOURCE OF DISCRETE INPUT INFORMATION PULSES, AN INPUT DIODE CONNECTED BETWEEN SAID INPUT PULSE SOURCE AND THE BASE ELECTRODE OF SAID TRANSISTOR, A SOURCE OF SYNC PULSES, A CAPACITOR CONNECTED BETWEEN SAID SYNC PULSE SOURCE AND THE BASE ELECTRODE OF SAID TRANSISTOR, AND A DISCHARGE CIRCUIT FOR SAID CAPACITOR, SAID CAPACITOR BEING CHARGED THROUGH SAID INPUT DIODE UPON THE APPEARANCE OF AN INPUT PULSE COUPLED WITH THE TERMINATION OF A SYNC PULSE TO MAINTAIN SAID TRANSISTOR IN ITS OFF STATE WHEREBY NO OUTPUT IS PRODUCED DURING THE PRESENCE OF SAID INPUT PULSE, SAID CAPACITOR BEING DISCHARGED UPON TERMINATION OF SAID INPUT PULSE COUPLED WITH THE APPEARANCE OF ANOTHER SYNC PULSE, AND THEN CHARGED UPON TERMINATION OF SAID OTHER SYNC PULSE THROUGH THE BASE-EMITTER CIRCUIT OF SAID TRANSISTOR TO EFFECT TURN ON OF THE TRANSISTOR WHEREBY AN OUTPUT IS PRODUCED INDICATING THE ABSENCE OF AN INPUT PULSE.
