Pulse to pulse power control system

Claim 1

IN A SYSTEM FOR CONTROLLING THE POWER OUTPUT LEVEL OF A TRAVELLING WAVE TUBE AMPLIFIER ON A PULSE TO PULSE BASIS WHERE THE FREQUENCY CHANGES ON EVERY PULSE COMPRISING A MULTIPLICITY OF GATED OSCILLATORS, EACH OF SAID OSCILLATORS HAVING A DIFFERENT PRESELECTED FREQUENCY, MEANS TO GENERATE AT PRESELECTED TIMES A SEPARATE GATING PULSE FOR EACH OF SAID OSCILLATORS, ONLY ONE OF SAID PULSES BEING OPERATIVE AT ANY ONE TIME, A TRAVELLING WAVE TUBE AMPLIFIER WITH THE POWER OUTPUT LEVEL THEREFROM BEING A FUNCTION OF THE MAGNITUDE OF VOLTAGE APPLIED TO THE COLLECTOR THEREOF, SAID TRAVELLING WAVE TUBE AMPLIFIER RECEIVING THE OUTPUT SIGNALS FROM SAID GATED OSCILLATORS, A SOFT TUBE MODULATOR HAVING THE OUTPUT THEREOF CONNECTED TO SAID COLLECTOR, A POWER SUPPLY CONNECTED TO SAID MODULATOR BY WAY OF A SERIES REGULATOR TUBE, A BOX-CAR GENERATOR HAVING TWO INPUT SIGNALS, THE FIRST BEING SAID OPERATIVE GATING PULSE TTO ACTUATE SAID BOX-CAR GENERATOR TO PROVIDE AN OUTPUT PULSE THEREFROM, AND THE SECOND INPUT SIGNAL BEING A PULSE HAVING A PRESELECTED DELAY TO DISCHARGE SAID OUTPUT PULSE, SAID BOX-CAR GENERATED OUTPUT PULSE HAVING AN AMPLITUDE EQUAL TO THAT OF SAID FIRST INPUT PULSE, AND AN AMPLIFIER INTERCONNECTING SAID SERIED REGULATOR TUBE AND SAID BOX-CAR GENERATOR TO PROVIDE A SIGNAL TO SAID SERIES REGULATOR TUBE TO CONTROL THE OUTPUT AMPLITUDE THERE OF.
