Abstract

262,979. Humphrys, W. E. H. Jan. 27, 1926. Thermionic amplifiers and detectors. - In a wireless receiver in which the valves are fed from the mains, the hum. is eliminated by employing a telephone transformer A in the output circuit and connecting one or more chokes F, G, in series with tho telephones or loud-speaker. The primary of an intervalve transformer may serve as the choke and the secondary winding may be either disconnected or, wholly or partially, shortcircuited or shunted by a condenser. The usual filtering devices for the supply current may additionally be employed.
