Abstract

412,182. Valve circuits. MUMFORD, A. H., 27, Grendon Gardens, Wembley Park, Middlesex, and BOURDEAUX, N., 18, Iver Lane, Iver, Buckinghamshire. Dec. 19, 1932, No. 35892. [Classes 40 (iii) and 40 (v).] A valve relay of the reciprocally-coupled type is arranged so that an increase in the anode current of one valve produces a decrease in the anode current of the other and so that the anode currents pass in opposite directions and with a "trigger" effect through a common load circuit. The arrangement is suitable for signalling by direct single or direct double current impulses (marking and spacing) or as a voice-operated relay for preventing "singing." A resistance R2 in the anode circuit of valve VI is in the grid circuit of V2, whilst a resistance R1 in the anode circuit of valve V2 is in the grid circuit of V1. The output or load 4 is common to both valves, though the two anode currents pass through the load in opposite directions. A positive impulse applied to the input terminal 3 increases the current flow through R2 and simultaneously tends to cut off the current through valve V2 by depressing the grid voltage until a steady current flows through the load 4. A succeeding input impulse of opposite voltage reduces the output current from the valve VI. Simultaneously the output from valve V2 increases, and progressively cuts down the output from VI by increasing the negative voltage across R1 until the current through the load 4 reaches a steady valve in the opposite direction. Specification 373,309 is referred to.
