Two state devices controlled by an input and phase-shifted signal applied to a trigger means of said devices

Claim 1

IN A DIFFERENTIAL REGULATOR COOPERABLE WITH A CYCLIC VOLTAGE SOURCE HAVING A VARIABLE PEAK AMPLITUDE: A TWO STATE DEVICE HAVING A HIGH IMPEDANCE OFF STATE AND A LOW IMPEDANCE ON STATE; TRIGGER MEANS FOR CONTROLLING THE PHASE ANGLE AT WHICH THE DEVICE CHANGES ITS STATE; SAID TRIGGER MEANS HAVING TWO VARIABLES THAT MUST REACH A CHARACTERISTIC PROPORTIONATE RELATIONSHIP TO EACH OTHER IN ORDER TO TRIGGER; FIRST MEANS DERIVING FROM SAID SOURCE A FIRT SIGNAL VOLTAGE PROPORTIONAL TO THE PEAK AMPLITUDE OF SAID SOURCE; SECOND MEANS DERIVING FROM SAID SOURCE A SECOND SIGNAL PORPORTIONAL TO THE INSTANTANEOUS AMPLITUDE OF SAID SOURCE BUT IN FIXED SPACED PHASE RELATIONSHIP TO SAID SOURCE; MEANS APPLYING SAID SIGNALS AS SAID VARIABLES TO SAID TRIGGER MEANS SO THAT THE OPERATING ANGLE OF SAID TRIGGER MEANS IS CORRELATED TO THE PEAK AMPLITUDE OF SAID SOURE TO MAINTAIN CONSTANT THE AVERAGE AMPLITUDE PASSED BY SAID TWO STATE DEVICE.
