Title: Improvements relating to means for regulating the output voltage of vapour electric rectifiers
IPC: H02M7/15
Filed: 1929-05-10
Abstract: 311,388. British Thomson-Houston Co., Ltd., (Assignees of Acheson, M. A., and Zehner, J. L.). May 10, 1928, [Convention date]. Vapour and vacuum or low-pressure apparatus, arrangements of. - The output voltage of a vapour-electric rectifier installation is maintained constant or caused to vary in a predetermined manner under variations in load current by imparting to a control grid a potential which varies directly as the voltage drop in the load circuit and inversely as the positive ion current flowing to the grid. This is effected, in a circuit in which a load 14 is supplied through a pair of gas-filled rectifiers 4, 5 associated with a transformer 3, by connecting the grids 10 through adjustable impedances 11 to a part of the lead circuit at a lower potential than the cathodes 9, e.g., the negative output terminals as shown. Fluctuations in grid potential are smoothed out by condensers 12 connected between the grids and the cathodes. A smoothing condenser 13 may also be connected across the load circuit terminals.

Title: Improvements in or relating to devices for measuring pressures
IPC: G01L9/12
Filed: 1956-05-11
Abstract: 804,724. Electric indicating systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 11, 1956 [May 16, 1955], No. 14722/56. Class 40 (1). Apparatus for measuring the pressure applied to the central, movable electrode of a differential capacitor comprises means for obtaining an A.C. voltage proportional to the displacement, which is rectified and fed back to the fixed electrodes to produce a force on the moving electrode to bring it back to its zero position. As shown, displacement of the central, movable electrode of differential capacitor 1, whose fixed electrodes are fed with A.C. from an oscillator 2, by a pressure to be measured produces a P.D. between points 3, 4 which is amplified at 5 and rectified at 6 to give a D.C. voltage indicated on meter 12 whose magnitude and polarity are indicative of the extent and direction of movement of the central electrode of capacitor 1. The fixed electrodes are also fed with equal values of this D.C. voltage but of opposite polarity, biased by a battery 17, to produce a force on the moving electrode to oppose the pressure displacement and bring the central electrode back to its zero position. The measuring range is varied by altering the voltage of battery 17.
