Abstract

526,173. Valve relay circuits. RYALL, L. E. March 8, 1939, No. 7529. Addition to 525,470. [Class 40 (v)] The oscillating, amplifying valve 10 of the parent Specification is adapted to amplify modulated carrier current signals instead of voice frequency signals. The oscillation circuit 15, 31 is tuned to the frequency of the incoming carrier, thus giving the valve circuit a single peak response or the circuit is made aperiodic and the quiescent oscillation is outside the band width of the modulated carrier.
