Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
131 words
A GATING CIRCUIT COMPRISING: A MONOSTABLE BLOCKING OSCILLATOR; SAMPLING GATE MEANS CONNECTED TO SAID OSCILLATOR, FOR TRANSMITTING A PORTION OF AN A.C. INPUT SIGNAL APPLIED TO THE INPUT TERMINAL OF SAID GATE MEANS THROUGH THE GATE MEANS TO ITS OUTPUT TERMINAL WHEN SAID GATE MEANS IS RENDERED CONDUCTING BY AN OUTPUT GATING PULSE PRODUCED BY SAID OSCILLATOR; BIAS MEANS FOR RENDERING SAID GATE MEANS NORMALLY NONCONDUCTING; AND DELAY MEANS WITHIN SAID OSCILLATOR FOR CAUSING SAID OSCILLATOR TO PRODUCE THE OUTPUT GATING PULSE ONLY AFTER THE OSCILLATOR IS TRIGGERED, DRIVEN INTO A SATURATED CONDUCTING STATE AND RETURNED TO A NONCONDUCTING STATE SO THAT THERE IS A TIME DELAY BETWEEN THE APPLICATION OF A TRIGGER PULSE TO SAID OSCILLATOR AND THE PRODUCTION OF THE OUTPUT GATING PULSE WHICH RENDERS SAID GATE MEANS CONDUCTING.
