Abstract
347,865. Valve detecting circuits. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, and LUDENIA, W., 57, Holsteinische Strasse, Steglitz, both in Berlin. April 16, 1930, No. 12109. Convention date, April 24, 1929. [Class 40 (v).] A receiver for ultra short waves comprises a super-regenerative valve circuit in which the valve oscillates according to the Barkhausen-Kurz methoc i.e. the grid is at a higher positive poten tial than the anode. The Figure shows an arrangement in which the quenching oscillations may be applied by transformer T<1> or T<2>. Specification 198,757, [Class 40 (v), Wireless signalling &c.], is referred to.
