Title: Remote control for pipeline pumping engines
IPC: F02N99/00
Filed: 1956-07-12
Abstract: 808,745. Engine turning gear. CATERPILLAR TRACTOR CO. July 12, 1956 [Aug. 3, 1955], No. 21564/56. Class 7(5) [Also in Group XXVI] A remote control for a series of slave engines actuating pumps spaced throughout the length of a fluid transmission line, comprises a fluid driven starting motor on each slave engine to be started, a master engine in advance of those to be started, means to direct fluid under pressure from the master engine and the transmission line adjacent each slave engine to be started through its starting motor and means responsive to pressure changes in the line adjacent each slave engine to be started to actuate the means for directing fluid through its starting motor whereby variations of the speed of the master engine and its pump will effect starting of the slave engines. Fig. 1 shows a fluid transmission pipeline, e.g. for transmitting oil to a refinery from a collecting point near a group of oil wells. All the engines except the one nearest the collecting tank are provided with a remotely controlled starting and stopping system. Fig. 2 shows one of the slave engines: Both engines Nos. 2 and 3 are equipped identically to' the engine shown in Fig. 2. When a pipeline requires additional slave engines they will be equipped with the same starting and stopping system as Nos. 2 and 3. When the pressure in the pipe 11a reaches a predetermined pressure the valve spool 18 moves to the right and admits oil to a conduit 20 which is in communication with a pilot pressure chamber 21 of a starting valve 22. The starting valve 22 is then opened and pipe line fluid is admitted to tne starting motor 24. As soon as the slave engine has started the pump 13 will cause. a pressure differential between the pump intake side and the discharge side 11b. The valve spool 18 closes. The higher pressure at the discharge side 11b will be directed to a pilot chamber 31 of a starting cycle terminator valve 32 by means of a conduit 33. The valve 32 opens and fluid in the line 20 is relieved of pressure and the starting motor valve 22 is closed. If the slave engine is adapted to operate on the fluid being pumped the drain tank 35 may serve as a fuel reservoir. In Figs. 3 and 4 portions of the engine governor and fuel control system are shown associated with an engine shut down mechanism adapted to shut off the fuel to a diesel engine upon either a loss of the lubricating oil pressure or a decrease in the fluid pressure in the pipeline 11. This shutdown mechanism is fully described in Specification 726,753 [Group XXVI] referred to. In that Specification the shutdown mechanism is shown also provided with an overspeed governor adapted to shut off the fuel to the engine upon exceeding a predetermined speed. The slave engines are stopped in a chain reaction resulting from a decrease in pipeline fluid pressure at the master engine No. 1.

Abstract: 1,150,422. Controlling activity of palladium catalyst. STANDARD OIL CO. 16 May, 1966 [17 May, 1965], No. 21657/66. Heading B1E [Also in Division C2] The activity of a palladium reducing catalyst is controlled by treating the catalyst with liquid formic acid at a temperature of at least 100‹F., preferably at its boiling point. The activity of fresh catalyst is reduced and that of spent catalyst at least partially restored. The formic acid is then removed by evaporation or distillation. The catalyst may contain 0.05% to 1 % by weight palladium supported on charcoal, and may be used in the purification of aromatic polycarboxylic acids, for example terephthalic acid; containing 4-carboxybenzaldehyde.

Title: Improvements in or relating to grid-controlled current converters
IPC: H02M1/04
Filed: 1957-07-09
Abstract: 812,103. Rectifying. SIEMENS-SCHUCKERTWERKE A.G. July 9,1957 [July 17, 1956], No. 21735/57. Class 38 (2). [Also in Group XL (c)] The control grid of a valve 1 through which D.C. is supplied to a load 10 from an A.C. source 11 receives a voltage dependent on the voltage drop across resistor 2 the current in which passes through the emitter-collector circuit of transistor 3, the value of this current being controlled by varying the value of direct voltage from source 5 superimposed on alternating voltage from source 4 in the base-emitter circuit. The transistor current is derived from a voltage connected to terminals 7, 8. So that the grid of valve 1 may be negative to block conduction when the transistor is non-conductive, a voltage from potentiometer 9 across terminals 7, 8 is superimposed on the voltage from resistor 2. Rectifier 6 limits the transistor reverse voltage. When a higher control voltage is needed, a number of transistors may be connected with their emitter-collector paths in series across a supply voltage, the superimposed alternating and unidirectional voltages being applied to the first transistor, and the bases of the other transistors being connected to suitable points along a potentiometer connected across the supply voltage (Fig. 5, not shown).

Abstract: 916,509. Television pick-up tubes. ENGLISH ELECTRIC VALVE CO. Ltd. March 17, 1961 [June 23, 1960], No. 21973/60. Class 39 (1). [Also in Group XXII] A process for manufacturing fine metal mesh for use in television camera tubes comprises the steps of preparing a plate e.g. of glass, with finely spaced cross lines of chemically deposited electrically conductive material e.g. lead sulphide, depositing a thin film of rare metal e.g. gold, on said lines of conducting material, depositing a thin layer of chromium on the rare metal, depositing the metal of which the mesh is to be made, e.g. copper or nickel, on to the chromium until a mesh of the desired thickness has been built up, and then pulling away the mesh to strip it away from the chromium. The lines on the plate may be in the form of grooves with the electrically conductive material therein. Such grooves are formed by a photographic exposure, development and etching process followed by an acid etch. Alternatively, the acid etch is omitted and the gold is deposited on the lines of lead sulphide on the surface of the plate after which the chromium is deposited on the gold to form a permanent master.

Abstract: 697,971. Extra air admission devices. CARBER MANUFACTURING CO. (PROPRIETARY), Ltd. Sept. 7, 1950 [Sept. 26, 1949]. No. 22023/50. Class 7 (ii). An extra air admission device comprises a casing 1 housing a double valve 7 and associated valve seats 5, 6. A chamber. above the casing is divided into two compartments 2, 23 by a pressure responsive diaphragm 3. The compartment 2 is connected to the interior of the casing 1 and the chamber 23 is connected to the venturi of the carburetter normally by means of a flexible pipe not shown. In use the device is connected to the induction pipe by means of a flange 22 which is attached to an adaptor (not shown) which is fitted between the carburetter and the induction manifold. When the engine is idling the air flow in the carburetter is too slow to produce sufficient depression in the chamber 23 to open the valve, With increased flow the valve opens and air flows past an oil bath type air cleaner and upper and lower valve seats 5, 6 into the induction manifold. With the valve partially open further opening of the valve is opposed by engine suction. At larger throttle openings the valve is opened further. The operation can be regulated by controlling the flow of air to the upper valve seat by means of a screw 19. The valve may be acted on by a spring for damping purposes. An extension 25 of the valve stem serves to indicate the position of the valve.
