Title: Improvements in or relating to electrical phase-shifting circuit arrangements
Inventor: DUNTHORNE DONALD
IPC: H05B39/08
Filed: 1957-12-11
Abstract: 868,417. Pulse delay circuits. GENERAL ELECTRIC CO. Ltd. Dec. 9, 1958 [Dec. 11, 1957], No. 38555/57. Class 40(6) [Also in Group XXXV] In a circuit for producing an output pulse having a variable delay with respect to an input wave, the input wave is applied through a rectifier to charge a capacitor which thereafter discharges through a resistor, the capacitor voltage being applied together with a variable reference voltage to a trigger circuit which operates at a capacitor voltage dependent upon the reference voltage to producing an output pulse. As shown, an alternating input voltage is applied to a transformer T and a rectifier 2 so that each alternate peak charges a capacitor 3. The capacitor thereupon discharges through a resistor 4 and the resulting voltage is applied to one grid of a trigger circuit 5, 6 the other grid of which is supplied with a reference voltage from a potentiometer 16. When the capacitor voltage has discharged to the reference voltage level, valve 6 becomes conducting producing a sudden fall in anode voltage. This fall is delayed with respect to the peak of the input voltage by an amount which is adjustable by varying the setting of the potentiometer 16. The fall is differentiated by components 23, 19 (diode 24 being conducting) and triggers a socalled "phantastron" circuit which produces an output pulse at its screen grid of a length determined by the setting of resistor 19. This output pulse is differentiated by components 26, 27. The trigger circuit is restored to its initial condition when the next positive half cycle of the input wave charges capacitor 3 to a value exceeding the reference potential from potentiometer 16, the resulting rise of voltage across resistor 9 being prevented from operating the "phantastron" by diode 24.
