Abstract

396,822. Wireless receiving-apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and HUGHES, D. H., c/o General Electric Co., Stoke, Coventry. Feb. 18, 1932, No. 4825. [Class 40 (v).] In a wireless receiver having a variable resistance 10 associated with the input circuit and the reaction circuit and adapted to control simultaneously the energy applied to the tuned input circuit 2, 3 and fed back by the reaction coil 8, the resistance 10 is graded and have a range of low values at the end which is in shunt to the input circuit. Specification 391,469 is referred to.
