Abstract

589,126. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. May 27, 1941, No. 6781. [Class 40 (v)] In a system for generating pulses of short duration and high power from a source of alternating potential, the frequency of the plate supply in any stage of a cascade amplifier is arranged to be an integral submultiple of the frequency of the source. Fig. 1 shows an amplifier of the type described in Specification 582,752 to which the invention may be applied. The source feeds the pentodes PI, P2 through transformer T with voltages displaced slightly from phase opposition by condenser C and limited by resistances RO and diodes D. The combined output is fed to cathode follower V. By using alternating potentials at integral submultiplesof the source to energize the anodes of the valves P1, P2 and V, steeper pulses are obtained. Fig. 6 shows an arrangement for securing increased sharpness in the pulses by the provision of additional stages P3, P4 and P5, P6. In this arrangement transformer T may be fed with frequency 32f and the supply to valves P1, P2, P5, P6 be 16f and to valves P3, P4 be 4f and to valve V be f, where f is the desired frequency of repetition of the impulses.
