Abstract

238,003. Melinsky, M. M. May 8, 1924. Thermionic amplifiers, detectors, and generators. - The anodes of one or more valves are earthed either directly or through a condenser and there is included in the grid connection of one or more of the valves one or more low resistance oscillatory circuits f. Fig. 1 shows a valve e<1> arranged for detecting and Fig. 3 the addition of a low frequency valve V2 the secondary of the transformer o, being connected to the grid and through a condenser o2 to the anode e<2> and hence to earth h or alternatively to the negative side of the filament or a grid-biasing battery. An arrangement with a high frequency amplifying valve having a tuned anode circuit and connected to a detecting valve arranged as in Fig. 1 is also described in the Specification. A frame aerial may be used and connected between earth h and the aerial side of the condenser d. A transmitting circuit may be formed from the circuit in Fig. 1 by connecting the aerial side of condenser d to earth h and substituting the circuit c for the telephones j the aerial being connected to the high tension end of this circuit.
