Title: Improvements relating to electrical gating circuit arrangements
Inventor: SCOLES GRAHAM JOHN
IPC: H03K17/54
Filed: 1951-10-03
Abstract: 719,785. Valve gating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 12, 1952 [Oct. 3, 1951], No. 23077/51. Class 40 (6)  A gating circuit comprises a gating valve and two control valves which are connected so that the gating valve is conductive to pass the signal to be gated only during the periods in which the alternating voltages which are applied in pushpull to the control grids of the control valves are below a pre-determined amplitude. The Figure shows a gating valve V3 to the grid circuit of which the signal to be gated is applied. An alternating control signal is applied through a phase-shifting circuit PSC in push-pull to the grids to the control valves V1 and V2 which have a common cathode resistor R with the gating valve V3. Valve V3 thus conducts to pass signal E at terminals IN only when the voltages applied to the grids of valves V1 and V2 have both an amplitude which is less than a predetermined value, Fig. 2 (not shown), which can be varied by adjustment of the grid bias of the gating valve. The gating valve may be arranged to gate a recurrent waveform in which case the alternating control voltage is synchronized with the waveform to be gated. The circuit may be used to gate the output from a light-or-heat sensitive cell-as described in Specification 642,697, [Group XL(b)]. Specification 630,075 also is referred to.
