Title: Improvements relating to electric signalling systems employing thermionic valves
IPC: H04Q1/446
Filed: 1945-05-11
Abstract: 594,159. Voice frequency signalling. SIEMENS BROS. & CO., Ltd., CRUTCH, L. S., MOLE, J. H., and NEWMAN, W. C. May 11, 1945, No. 11913. [Class 40 (iv)] [Also in Group XL] In a single valve circuit for controlling the operation of a relay in response to a particular signalling frequency, the facility for guarding against false operation by speech frequencies is provided without using any auxiliary relays by associating two output electrodes of the valve respectively with the relay and a circuit tuned to t e particular frequency, and also associating one of these electrodes with a circuit tuned to a different frequency, the outputs of the two circuits being rectified separately to provide direct voltages for application in opposition to a second control electrode. Circuits TRG, TRS are tuned to the particular frequency and a subharmonic respectively and voltage doublers RG, RS develop direct voltages across resistors TG, YS for application in opposition to the suppressor grid of valve VA. In general, the biassing voltages in resistors YG, YS are balanced and valve VA conducts to operate relay A. For inputs at the particular frequency, circuit TRG gives an accentuated response and the suppressor grid is driven negative to reduce the anode current below the operating level for relay A. Alternatively, the output of rectifier RS may be applied to the control grid as feedback to drive the grid more positive. Circuit elements YSS, CS introduce a delay to improve immunity from operation by speech frequencies.
