Abstract
534,820. Valve generating circuits MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEALL, O. E. Aug. 18, 1939, No. 23826. [Class 40 (v)] An oscillation generator comprises a single valve stage T with a filter circuit F connected between the grid and a tapping-point on the anode impedance Ro. The circuit oscillates at the frequency at which the filter gives 180 degrees phase displacement. The filter may comprise series condensers and shunt resistances as shown, series resistances and shunt condensers, Fig. 2 (not shown), series inductance coils and shunt resistances, Fig. 3 (not shown)), or series resistances and shunt inductance coils, Fig. 4 (not shown). Multiple filters selectable by a switch may be provided for giving different frequencies, or one or more of the elements may be variable for this purpose. Specification 395,596 is referred to.
