Abstract
150,701. Ges. f³r Drahtlose Telegraphie. Sept. 6, 1919, [Convention date]. Thermionic relays and detectors.-In a thermionic receiver of the type in which the grid and anode circuits are retroactively coupled together, incoming oscillations are interrupted at audio-frequency by an interrupter inserted either between the antenna and the valve or between the valve and the telephone receiver. In Fig. 1 the interrupter 6 is inserted in the grid oscillatory circuit 2. The retroactive coupling is adjusted so that the valve almost self-oscillates. According to a modification, the interrupter 6 is connected in parallel with the retroactive winding 4. In a further modification, Fig. 3, a high-frequency choke 7 in the anode circuit of the valve is periodically short-circuited across a condenser 8 by an interrupter 6.
