Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
IN COMBINATION WITH A SILICON CONTROLLED RECTIFIER, CIRCUIT MEANS FOR REGULATING THE OUTPUT THEREOF COMPRISING A TRANSISTOR, MEANS FOR SUPPLYING A VARIABLE INPUT SIGNAL TO SAID TRANSISTOR TO PRODUCE RESPONSIVE CHANGES IN THE TRANSISTOR CURRENT, A CAPACITANCE CONNECTED TO RECEIVE CURRENT FROM SAID TRANSISTOR, MEANS FOR APPLYING THE VOLTAGE DEVELOPED ACROSS SAID CAPACITANCE TO THE SILICON CONTROLLED RECTIFIER TO DETERMINE THE FIRING THEREOF, WHEREBY SUCH FIRING IS A FUNCTION OF THE INPUT SIGNAL TO THE TRANSISTOR, DISCHARGE CIRCUIT MEANS FOR SAID CAPACITANCE INCLUDING A RESISTANCE DEVICE AND A RECTIFIER THEREBETWEEN, AND MEANS FOR APPLYING A PULSING DIRECT CURRENT VOLTAGE THROUGH SAID RESISTANCE DEVICE TO SAID RECTIFIER, THE RECTIFIER BEING RENDERED CONDUCTIVE AT A PREDETERMINED VOLTAGE VALUE IN EACH PULSATION THUS APPLIED TO ITS CATHODE FOR DISCHARGING OF SAID CAPACITANCE.
