Abstract
420,686. Valve circuits for wireless reception. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. June 6, 1933, No. 16271. Convention date, June 4, 1932. [Class 40 (v)] Relates to valves, amplifiers, rectifiers, or oscillators of the type described in Specification 418,132, and consists in means for applying variable control voltages either to the electron density-regulating grid G1 or to the velocity-regulating grid G2, or to both. The control voltages may be varied manually, by means of adjustable tappings from the high-tension battery B, or they may be derived from known systems of automatic volume control.
