Abstract
341,786. Valve detecting circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) March 26, 1930, No. 9704. Convention date, March 30, 1929. [Class 40 (v).] In a superregenerative receiver the input L1 C1 is applied to a pair of valves 1, 2 in parallel having the quenching frequency from a source F applied to their grids in phase opposition. Feed-back coils T, Tr are included in the plate circuits of the valves and coupled to the input circuit L1 C1 the one to feed back energy in a reverse sense to the other so as to produce rapid quenching, as the valves are rendered alternately active by the quenching frequency. Specification 325,482, [Class 40 (v), Wireless signalling &c.], is referred to.
