Claim 1
Independent Claim
126 words
A CIRCUIT FOR PRODUCING A VOLTAGE PULSE, INCLUDING, A SOURCE OF A VOLTAGE PULSE OF VERY SHORT DURATION, A CAPACITOR CONNECTED BY A FIRST OF ITS PLATES TO THE SOURCE, A TRIODE TYPE OF TRANSISTOR CONNECTED TO THE SECOND PLATE OF THE CAPACITOR AT ITS BASE, A DIODE CONNECTED TO THE BASE OF THE TRANSISTOR SO AS TO FUNCTION AS A DISCHARGE PATH TO GROUND FOR THE CAPACITOR, A UNIJUNCTION TRANSISTOR CONNECTED BETWEEN THE EMITTER OF THE TRIODE TRANSISTOR AND GROUND, A RESISTANCE OF PREDETERMINED VALUE CONNECTED TO THE COLLECTOR OF THE TRIODE TRANSISTOR, AND A RELAY CIRCUIT CONNECTED BETWEEN THE JUNCTION OF THE RESISTANCE AND THE COLLECTOR AND A SOURCE OF LOW VOLTAGE POWER TO RECEIVE THE OUTPUT VOLTAGE PULSE PRODUCED BY THE FOREGOING CIRCUIT.
