IPC: H01B17/00
Filed: 1931-05-01
Abstract: 376,869. Supplying low voltage apparatus; condensers. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Peters, J. F. ; 405, Hutchinson Avenue, and Marbury, R. E. ; 419W, Hutchinson Avenue, Edgewood, Pennsylvania, U.S.A.) May 1, 1931, No. 12885. Convention date, May 1, 1930. [Classes 38 (ii) and 38 (iv).] In a method for obtaining low voltage power from high voltage alternating current overhead transmission lines 4, an inductance 5 and the load 7 are shunted across one 1 of a number of series connected capacitor units so that the capacitor, inductance and load form a substantially resonant circuit wherein a relatively large current of relatively low voltage can be obtained, whilst a relatively small current only is drawn from the transmission line. In a modification the primary winding of a transformer is introduced into the resonant circuit, the load being arranged in the secondary circuit of this transformer. Fig. 3 illustrates a desirable form of suspension capacitor unit which comprises a cylindrical casing 11 of porcelain with a cap 12 and a base 13, the units being linked together by projections 14 engaging orifices 15 in the caps. In an interior cylinder 16 of insulating material and with liquid tight end caps, are placed the condenser units 17, each formed of strips of metal foil and paper wound on a core of fibreboard and immersed in insulating wax, the container 16 being then filled with insulating oil. The units 17 are mounted in series upon a base plate 18 and separated by insulating spacers 19. The linked capacitor units may support the line conductor and thus function also as a line suspension insulator, or they may themselves be suspended from suspension insulators and connected at the upper end to the line conductor.

IPC: F02M3/09
Filed: 1919-05-23
Abstract: 145,228. Willis, G. B. May 23, 1919. Spray carburettors.-The operating-means of the throttle valve 1 and the valve 11 controlling the slow-running passage 9 are interconnected so that one valve is opened as the other valve is closed, the connexion being such that the slowrunning valve 11 can be further operated, to regulate the supply of slow-running mixture, after the throttle valve 1 is fully closed. The throttle valve 1 is rotatably mounted upon a spindle 3 carrying the slowrunning valve 11, the valves being provided with operating-levers 13, 12 which are interconnected by a rod 14 jointed to the lever 12 and passing freely through an eye 15 in the end of the throttle lever 13; an adjustabl,e stop 16 is provided on the end of the rod 14, and a spring 17 is interposed between the levers. When the lever 12, which may be operated from the driver's seat, is moved in one direction, the throttle lever 13 is operated positively by the stop 16 and the throttle valve 1 is opened whilst the slow-running valve 11 is closed; when the lever 12 is moved in the other direction, the slow-running valve is opened and the throttle valve is closed through tho medium of the spring 17 ; further movement of the lever 12 in the same direction turns the spindle 3 relatively to the throttle valve, the spring 17 being compressed, and the slow-running valve 11 is more or less closed, thus regulating the supply of slow-running mixture.

Title: Process of manufacturing laminated sheet glass
IPC: B32B17/10
Filed: 1928-05-02
Abstract: 304,539. Watt, J. A. May 2, 1923. Compound sheets.-The glass used in forming compound transparent or translucent sheets is given a roughened or pitted surface where joined to the intermediate layer of non-brittle material, e.g. celluloid, to provide a better bond with the adhesive used. The roughening may be formed by dilute hydrofluoric acid or aqueous solutions of fluorides with strong mineral acid, or by other chemical means, or by sandblasting or other mechanical means when translucency only is required. A dilute solution of adhesive such as gun-cotton dissolved in acetone, is preferably first applied to the roughened glass to make more intimate contact therewith; this is followed by a more viscous solution. The celluloid &c. is softened by a solvent such as amyl acetate and the surfaces to be joined are coated with an inert lubricant, such as transparent oil, which assists the removal of air bubbles, and then united under pressure. When making transparent sheets, the pits &c. should not be greater than 20 microns so as to be invisible.

Title: Liquid dispensing and vapour recovery apparatus
IPC: B67D7/54
Filed: 1976-03-31
Abstract: 1505023 Liquid dispensing apparatus WEIL-McLAIN CO Inc 31 March 1976 [31 March 1975 4 April 1975] 12990/76 Heading B8N A liquid dispensing apparatus, particularly for petrol, comprises a conduit 22, 22a, 78 from a storage tank 10 to a dispenser 44, a second conduit 80, 24, Fig. 2, along which a portion of the liquid from the first conduit is diverted back to the tank and a third conduit 60 along which liquid vapour is sucked into the second conduit. The diverted liquid is directed through a Venturi 84 which creates a reduced pressure zone which is connected via a valve 116 to the third conduit 60 which extends from the dispenser 44. The valve 116 is controlled by a diaphragm 112 subjected to pressure upstream and downstream of a Venturi 102 through which the liquid to be dispensed flows. A valve 92 is spring-biased to close the second conduit 80 until the liquid is being dispensed. The valve 92 has a head which co-operates with a seat in the first conduit which allows flow into the conduit 78 when the stem of the valve closes the second conduit to equalize the pressure. When dispensing is initiated the drop in pressure in the conduit 78 causes the valve 92 to open and allow liquid to be diverted to the second conduit and create a back pressure in the Venturi 84. In a second embodiment a check valve 174, Fig. 3, is provided in the vapour return conduit 188 controlled by a Venturi 184 in the second conduit 180, 24 along which liquid is diverted.

Abstract: 1351894 A/D converters LA TELEMECANIQUE ELECTRIQUE 21 March 1972 [25 March 1971] 13227/72 Heading G4H A dual-ramp A/D converter is adapted to perform an initial charge-discharge-charge sequence to compensate for errors present in the unknown voltage presented to the integrator owing to the components of the converter itself. The apparatus comprises a reference input 1 and amplifier 3 and an unknown input 2 which is connected via switch 4 to a second amplifier 6, both inputs being presented to a second switching device 5 which provides the input to a capacitor-type integrator 7 having its output connected with a zero-detector 8 which is connected to two logic circuits 12, 13 which operate on a counter 10, store 14 and display 15. A clock-pulse source 9 is provided for the counter 10 and a third logic circuit 11 is provided to operate the switching devices 4, 5 in response to various zero-count conditions at 10. In operation and with the counter 10 registering zero, the switches 4, 5 are held at positions F2, F3 respectively to connect the integrator 7 to ground, and the counter counts to its maximum during which time the integrator 7 integrates voltages due to the errors in all components 4-7. At the maximum count, the counter 10 resets to zero and the device 11 causes switches 4, 5 to take positions F1 and F4 respectively and so a reference voltage is applied to the integrator 7 to discharge it, the device 8 via device 12 causing the counter 10 to reverse its direction at the zero output point of the integrator to count back to zero, at which time the switch 5 is moved to position F3. At this point, the integrator 7 is charged with the integral over time T of all error voltages affecting the unknown input 2, and with a reverse polarity to the unknown voltage. The last switching procedure connects the unknown voltage, together with any errors present, with the integrator 7 and the integration proceeds for a further time T, the time that the counter requires to count from zero to its maximum. When this resets once more, switch 5 switches back to F4 to cause the discharge of the integrator back to zero. When zero is reached, the device 8 via device 13 causes a store 14 and a display 15 to operate to give an indication of the unknown voltage value. The unknown input may be from a strain gauge bridge.
