Claim 1
Independent Claim
154 words
A SAW-TOTHED WAVE GENERATOR COMPRISING AN ELECTRON DISCHARGE DEVICE INCLUDING A CATHODE, A GRID AND AN ANODE, A SOURCE OF ENERGIZING POTENTIAL HAVING A POSITIVE TERMINAL, AN ANODE LOAD IMPEDANCE, SAID LOAD IMPEDANCE BEING CONNECTED BETWEEN SAID ANODE AND THE POSITIVE TERMINAL OF SAID SOURCE, A FIRST CAPACITOR CONNECTED IN CIRCUIT BETWEEN SAID GRID AND SAID ANODE, A FIRST RESISTOR CONNECTED BETWEEN SAID GRID AND THE POSITIVE TERMINAL OF SAID SOURCE, MEANS CONNECTED IN SHUNT WITH THE GRID-CATHODE PATH OF SAID DISCHARGE DEVICE FOR PERIODICALLY BIASING THE POTENTIAL OF SAID GRID WITH RESPEC TO SAID CATHODE BEYOND CUTOFF FOR SHORT INTERVALS OF TIME, WHEREBY A SAW-TOTB WAVE IS DEVELOPED BETWEEN SAID ANODE AND CATHODE ELECTRODES, A SECOND CAPACITOR AND A SECOND RESISTOR CONNECTED TO SERIES CIRCUIT BETWEEN SAID ANODE AND SAID CATHODE, SAID FIRST CAPACITOR HAVING THE END ADJACENT SAID ANODE CONNECTED TO THE JUNCTION POINT OF SAID SECOND CAPACITOR AND SAID SECOND RESISTOR.
