Title: Improved topping-up instrument for electric accumulators
Inventor: FIELD BRAHAM ROWLEY
IPC: H01M50/673
Filed: 1955-01-28
Abstract: 778,967. Portable containers. ALKALINE BATTERIES, Ltd. Jan. 12, 1956 [Jan. 28, 1955], No. 2597/55. Class 66. [Also in Group XXXVI] A device for topping-up accumulators consists of a flexible bottle a, e.g. of polythene, connected by a flexible transparent tube c to a rigid nozzle d, the nozzle having a flange or collar e which when seated on the filling orifice positions the open end of the nozzle at the normal electrolyte level. The bottle is squeezed before insertion of the nozzle into the filling orifice and is then released. If liquid is drawn into the tube c, no topping-up is necessary. If air is drawn into the tube, the accumulator is topped-up by squeezing and releasing the bottle repeatedly until liquid is drawn into the tube thereby indicating that the electrolyte is at the required level. The bottle is then lowered and squeezed to expel any residual liquid in the tube. A ball float may be placed in the tube to indicate when liquid is drawn in.

Title: Improvements in or relating to television apparatus
IPC: H01J31/28
Filed: 1958-01-27
Abstract: 815,773. Television. GRUNDIG, M. Jan. 27, 1958 [Jan. 26, 1957], No. 2623/58. Class 40(3). In a television transmission system utilizing a spirally scanned storage type of pick-up tube of the kind in which the sensitivity varies inversely as the velocity of scan and directly as the potential of the signal electrode, the contrast of the output signals is maintained constant by varying the potential of the signal electrode in a compensating manner. This is effected, as shown in the Figure, by deriving from the scanning generator 9 (which supplies the scanning coils 8 with a waveform consisting of two 90 degrees phase displaced sinusoidal oscillation of similar frequency modulated by a sawtooth wave), a sawtooth control voltage which is superimposed on the D.C. potential applied to the signal plate 3 so that, with the scanning and control voltage waveforms shown the sensitivity of the tube is increased progressively by the control voltage as the scanning velocity increases progressively.

Title: Carburetters
IPC: F02M69/00
Filed: 1945-02-06
Abstract: 591,471. Spray carburetters. BENDIX AVIATION CORPORATION. Feb. 6, 1945, No. 3029. Convention date, Dec. 27, 1943. [Class 7 (iii)] In a carburetter in which fuel under pressure is supplied into a throttle-controlled induction passage through a discharge nozzle valve and having a fuel metering jet in a fuel-supply line through which the fuel flows to the discharge nozzle valve, the effective area of the jet is controlled by a metering valve having three stages of operation in the first of which during idling or near idling the opening of the valve is limited independently of the normal control of the valve in the second during cruising the valve has a fixed open position and in the third stage above predetermined output the valve is controlled by fuel pressure upstream of the jet, air pressure from a venturi and a spring which resists the opening of the valve. As shown fuel under pressure enters the carburetter through a valve 210 and passes by a pipe 92 to a metering valve 116. From the valve the fuel passes to a discharge nozzle valve 68 and into the induction passage through a discharge nozzle 42. At idling the metering valve 116 is held close to its seat 120 by a a finger 134 on the throttle valve 30. The finger operates through the medium of a rod 129 cross-member 128 and sleeve 136 to control the valve. As the throttle is opened valve 116 is opened until a flange 142 on the sleeve engages 'a spring pressed collar 144. In this position the metering valve passes the right amount of fuel for cruising operation and retains this position during cruising conditions. For high power operation the suction produced at the throat of a venturi 20 by the increased air flow in the induction passage is utilised to withdraw the valve further from its seat 120. The suction acts on a diaphragm 110 connected to the valve. The valve 210 is controlled by a diaphragm 218 acted on by venturi entrance air pressure, by the pressure of the fuel upstream of the metering valve and by a spring 212. The valve 68 is operated by a diaphragm 66 controlled by venturi suction and pressure of the fuel downstream of the metering valve. A manually operated valve 260 may be employed to vary the rate of fuel flow by allowing a leakage of air from the pipes connected to the venturi entrance into those connected to the venturi throat and thus modifying the venturi suction pressure which operates the valve 68. The valve 210 can be closed by raising the manual valve 260 past a lean mixture position, a collar 256 then closing the valve positively through the medium of a lever 246, plunger 242, and lever 226. An altitude control 160 and an acceleration device 270, which function in a manner similar to those described in Specification 590,493, may be employed. The carburetter is similar to the carburetters described in Specifications 577,770, 590,493 and 590,528.
