Abstract

497,656. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 21, 1937, No. 17300. Convention date, July 19, 1936. [Class 40 (v)] A multi-vibrator circuit, comprising a reciprocally-coupled valve pair 10, 11, produces impulses of the same frequency as controlling- impulses applied through the condenser 18, but having an adjustable phase-displacement therefrom. The circuit is of the normal type employing coupling-condensers 14, 16 and grid resistances 15, 17. The phase of the generated impulses is adjusted by varying the time constants of the combinations 14, 15 and 16, 17 in opposite senses. Either the condensers or the resistances may be variable and they may be coupled together for simultaneous operation. The Specification includes diagrams. Figs. 2 and 3 (not shown), indicating the variations of the grid voltages of the respective valves plotted against time.
