Abstract
519,897. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., FEWINGS, D. J., and KEMP, R. J. Oct. 6, 1938, No. 29029. [Class 40 (v)] To produce push-pull deflecting-voltages for a cathode ray tube, condensers 9a, 9b, Fig. 1, are charged at uniform rates over resistances 12a, 12b and are discharged through valves 5a 5b when condensers 4a and 4b pass respectively negative and positive " pips." The " pips " are caused by pulses through transformer 3 generated by the blocking oscillator 1. The saw-tooth waves are amplified by valves 16a, 16b and are applied in phase opposition to plates 18a, 18b. In the embodiment of Fig. 3, the valve 27 replaces transformer 3, the necessary phase-reversal being obtained by inserting the condensers 9a and 9b respectively in the anode and cathode circuits of the valve 27.
