Abstract: 505,576. Exchange systems. AUTO. MATIC TELEPHONE & ELECTRIC CO., Ltd., TERRONI, T. B. D., and McCUSKER, J. B. Nov. 12, 1937, No. 31155. [Class 40 (iv)] In an electrical signalling system, discrimination between complex alternating currents and signalling currents having a frequency within the range of the complex currents, is effected by applying the incoming currents to the grid of a valve VA acting as a constant output device and including in the anode circuit of the valve a plurality of tuned circuits, one or more QB, QC, of which are each tuned to a signalling frequency, whilst an aperiodic circuit T3 tends to prevent the operation of signal responding devices. The tuned circuit QB includes the primary of a transformer T2. When the signal to which QB is tuned arrives, the neon lamp NA flashes and a positive potential is applied to the control grid of the valve VB, causing current to flow to operate the relay X. At the same time, a voltage is applied, through the voltage doubler MRA to the suppressor grid of the valve VC. When operated, however, valvo VC applies a, voltage through a voltage doubler MRC to the suppressor grid of valve VB. Valve VC is operated by complex currents to prevent the operation of X, and is not operated by signal currents. The resistance network comprising resistances YK, YL, and barretter BRA compensates for fluctuations in the supply voltage. The circuit QC, the valve VD, and the relay Y are arranged exactly in the same way as the circuit QB, the valvo VD and the relay X. Specification 507,746 is referred to.
