Abstract: 558,471. Supply systems for space discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. July 3, 1942, No. 9204. [Class 38 (iv)] [Also in Group XL] Intermittent illumination of a gas discharge lamp is obtained by using an indirectly heated thermistor or resistance of high temperature - resistance coefficient. In one arrangement the lamp N is connected in series with a constant resistance R1 and shunted by a thermistor R having a negative temperature coefficient ; the heating winding r and a control switch K are placed in series with the lamp and source S. The fall in resistance of R which occurs when the lamp lights reduces the terminal potential of the lamp to extinction point and the action repeats at a frequency and timing determined by the relation between circuit constants. A positive temperature coefficient thermistor would be arranged in series with the lamp with a constant resistance in shunt. The thermistor; with or without the constant resistance may be mounted in the same bulb as the lamp.

Patent GB-656152-A (GB)
Title: Multichannel electric pulse communication system
IPC: H04J3/18
Filed: 1948-04-02
Abstract: 656,152. Multiplex pulse signalling; pulse delaying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 2,1948, No. 9304. Convention date, April 2,1947. [Classes 40(v) and 40 (vi)] In a multiplex pulse communication system interchannel cross-talk is reduced by arranging by means of delay devices the pulses of each channel to form regularly-recurring groups of a fixed number of closely-spaced pulses corresponding to each channel and applying those groups in interleaved time relationship to the transmission medium. Thus the interleaved pulses A 1, B1, C1 ... J1, A2, B2, C2 ... J2, A3 ..., corresponding to channels A ... J, are regrouped in the form A1, A2, A3 ... An, B1, B2 ... Bn, C1 ... Cn, J1 ... Jn, with the spacing between rearranged pulses of each channel less than that of the original pulse train but the spacing between groups, e.g. An, B1, greater than the original mean pulse repetition period. If n = 10, and the number of channels is 10, A1 may be delayed 91 time units, A2 81.9 time units, A3 72.8 units &c., so allotting ten A channel pulses into a period of 8.1 units. Delay and modulation may be effected (Fig. 3) by cascades of networks or trigger circuits each connected, as shown, through rectifiers 18 blocking backcoupling, to dynodes of a cathode-ray tube distributer having a rotary electron beam striking a dynode at the moment a delayed modulated pulse is passed to it, a common collector electrode 30 feeding the transmitter. At the receiver a similar distributer synchronized by the group repetition period or by intervening marker pulses produces pulses of amplitude determined by the receiver on dynodes connected through decoupling rectifiers to delay lines restoring the original grouping before transmission, and low-pass filters demodulating the pulses. In place of delay lines the delay means may comprise cascades of flip-flops (Fig. 5, not shown). Restoration of conduction of the first triode produces a negative pulse on the input of the second flip-flop. A diode 110 shunted to earth between successive flip-flops eliminates back-coupling between them. The circuit delays may be shortened and stabilized by a common square waveform fed to tappings on the input and/or output grid circuits of the flip-flops, in push-pull or otherwise, and of period equal to or a sub-multiple of them. The cathode-ray tube distributers may be of the type described in Specifications 603,614 and 635,482. Specification 656,151 also is referred to.

Title: Improvements in valves for preventing reverse flow in pipe lines
IPC: F16K15/03
Filed: 1927-04-11
Abstract: 287,332. Blakeborough, R. A., Brotherton, C., and Wood, T. April 11, 1927, Valves controlled by pilot or relay valves.-A valve device for preventing reverse flow in pipe lines has a butterfly valve 4 actuated by a piston 8 working in a cylinder 9 and connected by a rod 7 and link 6 to the lower part of the valve. The valve is mounted on a shaft 3 pivoted in a detachable section 2 of the casing and co-operates with a liner 5. When the valve is open the link 6 is protected by a stream line tubular guard 6<1> engaging a corresponding boss 4<1> on the valve member. In the form shown in Fig. 2 the main valve is controlled by a four-way cock 12 having an exhaust connection 13 and connected to the actuating cylinder by pipes 10, 11 and to the main conduit through a two-way non-return valve 13 and pipe 14. The control cylinder 21 is connected by a pipe 21<1> to the upstream side of the main valve and contains a piston acting on a weighted lever 24 provided with catches 26, 27, 30 adapted to hold a tumbler weight 20 in either of two positions on each side of the vertical. The catch 27 is pivoted to the lever to allow the tumbler to pass in one direction, and the catch 30 is pivoted and counterweighted to bear against a stop 26<1> and is adapted temporarilv to hold the tumbler during the automatic resetting operation. In the event of the pressure falling, the catch 26 releases the tumbler, which falls and engages the arm 18<1> of a three-armed lever 18 connected by a link 17 to the cock 12 reversing the connections to the actuating cylinder. As the valve moves to its closed position a toothed quadrant 28 on the shaft 3 rotates a spur wheel 29 having a projection adapted to raise the tumbler into contact with the catch 27. When pressure is restored the catch 27 is released to permit the tumbler to fall and again reverse the connections, the subsequent opening movement resetting the tumbler in engagement with either catch 30 or 26, the control being finally passed to the catch 26. As the valve approaches its closed position a projection on the quadrant engages the lever 18 to retard gradually the closing movement. The release catches may be actuated by a paddle in the main conduit coupled to a hinged valve arranged to close the downstream end of a bye-pass conduit. The automatic resetting mechanism may be dispensed with in which case the control cock is provided with a handle for reversing the connections during the resetting operation.
