Abstract

411,416. Valve detecting circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Aug. 29, 1932, No. 24104. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 5, 1932]. [Class 40 (v).] In a wireless receiver a valve having a tuned input circuit and an inductive back-coupling, has a condenser 4 and resistance 5 arranged in series across the tuned circuit to maintain reaction constant. The condenser may have a value of 10-12 cms. and the resistance a value of 10,000-43,000 ohms and may be additional to the usual grid condenser and grid leak.
