Patent GB-1371901-A (GB)
Title: Liquid dispensing apparatus
IPC: B67D7/22
Filed: 1971-10-08
Abstract: 1371901 Dispensing liquids J D HOPPING AND G C SPENCER 8 Oct 1971 [13 Jan 1971] 1637/71 HeadingT In a liquid, e.g. petrol or mixture thereof, dispensing control system for separately controlling one or more pumps a peripherally apertured wheel 17, Fig. interrupts light from 19 to photoelectric sensor 20 and is enclosed in a gas tight base 11, 12, the wheel being driven by shaft 14 connected by polythene tube 15 to e.g. the pence shaft of petrol pump register. The alignment of light, sensor and aperture produces a signal representing say a quarter penny worth of petrol. The signal is amplified by a transistor and Schmitt trigger which sends a well defined pulse to a remote control console, where via transistors and two flip-flops in series, the first flip-flop halves the input train of pulses, whereby the first pulse is ignored and not counted and the halfpence signals sent to a diode display tube 53, Fig.4, while the second flip-flop quarters the train of initial input pulses and sends the penny signals via units, tens and hundreds binary counters and decoders 40 to numerical indicator tubes 50. Since the first pulse is not counted, a signal produced by a wheel aperture being in line with the light and sensor before petrol is dispensed will not be taken into account. An inter-connected switch and valve S4 resets the electronic indicators and allows air pressure to actuate a jack for zeroising the petrol pump register, switch S2 energizes the pump motor and the petrol pump is operated as a selfservice installation. Although alternate pulses are not counted as described any regular number of pulses can be ignored by using a suitable circuit.

Title: Improvements relating to fluid cooling of high power electron discharge tubes
IPC: H01J7/24
Filed: 1957-01-16
Abstract: 838,105. Cooling discharge apparatus. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Jan. 16, 1957 [Jan. 16, 1956], No. 1650/57. Class 39(1). [Also in Group XXXV] The temperature of a high power electron discharge device having a fluid-tight annular jacket through which cooling fluid is passed is automatically controlled by an arrangement comprising a temperature sensitive element in thermal contact with the inner wall of the jacket but thermally insulated from the cooling fluid in the jacket and means actuated by said element for controlling the rate of flow of cooling fluid. The tube shown is an Ignitron having a striking electrode connected to an external conductor 2 and an anode connected to a conductor 3. The envelope of the tube comprises two concentric cylindrical members 4 and 5 forming an annular jacket for cooling fluid which enters through an inlet 6 and leaves through an outlet 7. A cylinder 8 of metal such as copper which is a good heat conductor is surrounded by a heat insulating sleeve 9, which may be of plastic material, and is maintained in contact with the internal wall 4 by a fluid-tight ring-nut 10 screwed on to an annular flange 11 secured to the wall 5. A drop of soft metal such as silver may be compressed between the bottom of the cylinder 8 and the wall 4 to improve the thermal contact. The cylinder 8 is filled with a liquid having a high coefficient of expansion relative to that of the metal of the cylinder, and changes in volume of this liquid are communicated by a capillary tube 15 to a hydraulic regulator 16 to vary the flow of cooling fluid which may be entirely cut off when the temperature of the wall 4 is below a predetermined value. As an alternative, electrical control of the flow of cooling fluid may be obtained by utilizing the output of a thermo-couple or a thermistor provided in the cylinder 8.

Title: Improvements in or relating to wireless receivers
IPC: H03G3/22
Filed: 1936-01-25
Abstract: 469,428. Valve circuits for wireless reception. ROBINSON, J. Jan. 25, 1936, No. 2409. [Class 40 (v)] The gain of a heterodyne receiver is controlled in accordance with the beat frequency amplitude by varying the coupling between the local oscillator and the mixing valve. The beat-frequency signals may be combined with the local oscillations to produce a signal frequency for combination with the incoming signals to increase the effective selectivity and/or amplification of the receiver. In one embodiment a receiver comprises a preselector 10, Fig. 1, first detector 11, I.F. amplifier 12, second detector 13 and local oscillator 14 coupled to the first detector through a valve 15 of variable amplification. I.F. signals from the amplifier 12 are applied to a selector 16 feeding a rectifier 17 the D.C. output of which controls the bias on the grid 18 of the coupling valve 15 to give A.V.C. A portion of the output from the selector 16 is combined with local oscillations from the generator 14 in a rectifier 19 to produce a carrier wave component which is applied to the preselector 10, if necessary through a phase shifting device as described in Specifications 466,415 and 466,497. In a further embodiment the coupling valve 15 is replaced by a pair of valves 21, 22, Fig. 2, the outputs from which are in opposition for the local oscillator input applied through the transformer 20. The effective amplification of valve 22 is varied by the output from the rectifier 17 which is applied across a resistance 25 to the grid thereof. The valves also act as a mixing device for oscillations from the local oscillator 14 and selector 16 to produce the original carrier frequency for application to the first detector 11.
