Filed: 1950-05-04
Abstract: 703,686. Valve relay circuits. ENGLISH ELECTRIC CO., Ltd. May 4, 1951 [May 4, 1950], No. 11009/50. Class 40 (6) Fig. 5 shows a timer which operates from an A.C. supply in which normally relay A is de-energized and capacitor C4 is charged via resistor R7 by the anode current flow in valve V2. When push-button P is depressed to initiate a timing cycle capacitor C4 discharges through relay coil A which operates, contacts A3 open, contacts A2 change-over to discharge capacitor C4 via resistor R9 and contact Al connects the anode of valve V2 to the relay coil A. The charging circuit for the timing capacitor C1 is broken by the change-over of contact A1 so that C1 discharges through resistor R1 until valve V1 conducts when then reciprocally-coupted valve V2 is cut-off and relay A is released to terminate the timing period. A new timing cycle cannot be started until capacitor C4 is recharged and push-button P is depressed. It is shown that variations in timing period with changes in supply voltage are reduced as the effective grid potential of valve VI comprises a component derived from the current flow in valve V2 which varies with the mains supply voltage. Variations of the timing period with mains supply voltage are also reduced by connecting the heaters to valves V1, V2 in their respective cathode circuits. In a modification, Figure (Complete) (not shown), a re-cycling circuit is described which enables timing periods to be successively measured.

The voiced-unvoiced detector may cause switching between two alternative filters provided for each channel, Fig. 2 (not shown), or it may modify the filtercircuit, e.g. by operation of switch Si. in the filter of Fig. 3. A typical integrator circuit which might be used in each spectrum analysis channel is shown in Fig. 5 in which the spectrum channel signal is applied to band causes capacitor C to be discharged by an amount proportional to the current applied through R 1'  Periodically a signal is applied to line a to cause TR 2  to conduct to charge C up to the supply potential. The charging current, which will depend on the total discharge of C since the last charging pulse, flowing through R3 will produce an output pulse on Ki<SP>1</SP> the amplitude of which is proportional to the integral of the spectrum channel signal over a time equal to the period of the pulse signal applied to line a. The voiced-unvoiced discriminator output is employed to increase the period between the pulses applied to line b during unvoiced sounds.
