High gain superregenerative detectors

Claim 1

IN A SELF-QUENCHED SUPERREGENERATIVE DETECTOR POWERED FROM A SOURCE OF DIRECT-CURRENT OPERATING POTENTIAL AND HAVING ITS NORMAL QUENCH FREQUENCY DETERMINED IN ACCORDANCE WITH THE TIME CONSTANT FORMED BY THE PRODUCT OF A QUENCH RESISTANCE AND A QUENCH CAPACITANCE AND WHEREIN SAID QUENCH CAPACITANCE DISCHARGES DURING A PORTION OF EACH QUENCH VOLTAGE CYCLE IN ACCORDANCE WITH AN EXPONENTIAL CURVE WHICH ASYMPTOTICALLY APPROACHES THE DIRECTCURRENT OPERATING POTENTIAL APPLIED TO THE DETECTOR, THE IMPROVEMENT COMPRISING MEANS FOR SIMULTANEOUSLY, SELECTIVELY ONLY DURING THE PERIODS OF SIGNAL DETECTION AND DETECTOR OSCILLATION IN EACH QUENCH CYCLE, LENGTHENING THE QUENCH CIRCUIT TIME CONSTANT AND LOWERING THE STEADY STATE POTENTIAL TOWARD WHICH THE EXPONENTIAL DISCHARGE CURVE OF SAID QUENCH CAPACITANCE ASYMPTOTICALLY APPROACHES TO A PREDETERMINED CONSTANT VALUE LESS THAN SAID APPLIED DIRECT-CURRENT OPERATING POTENTIAL, SAID MEANS COMPRISING AN IMPEDANCE AND SWITCHING CIRCUIT SERIES CONNECTED WITH SAID QUENCH RESISTANCE ACROSS SAID SOURCE OF DIRECT-CURRENT OPERATING POTENTIAL.
