Patent GB-978362-A (GB)
Title: Liquid fuel injection pumps
Inventor: VOLOSSEVICH GEORGE
IPC: F02M41/14
Filed: 1962-04-16
Abstract: 978,362. Fuel injection pumps; starting fuel-injection engines. C.A.V. Ltd. April 4, 1963 [April 16, 1962], No. 14585/62. Headings F1A and F1B. In a fuel injection pump comprising a rotary distributer 12, Fig. 1, housing opposed pistons 9 engaging an annular cam track 11 and fed by a vane pump 2 at a pressure proportional to engine speed, a valve member 22 having control grooves 23, 24 is housed in the distributer and prevented from rotation therewith by a rod 25, the valve member being axially adjustable to vary the quantity of fuel injected and angularly adjustable to vary the injection timing. Valve member 22 is connected to rod 25 through a pin and slot 26 and is axially movable against a spring 31 by centrifugal governor 28, a drivercontrolled spring abutment 30 determining the compression of spring 31. For excess fuel for starting, a light spring 29 biases valve member 22 to the inward end of slot 26. During the delivery stroke of pistons 9, fuel is first bypassed to the delivery side 4 of the feed pump via inlet passage 18, passage 37, port 36, control groove 23, chamber 21 and port 38. Delivery to the injectors takes place via check valve 17 and passages 15 and 16 when port 36 is closed, and is terminated when port 36 is opened by groove 24. When the engine starts, the output pressure of the feed pump acts on the inner end of valve member 22 to move it against spring 29 to its normal running position. Valve member 22 is adjustable angularly to vary the timing by a spring-loaded piston 33 acting through arm 35 splined on rod 25 and connected at each end to the inlet and outlet sides, respectively, of the feed pump. A cut-off valve 42 is provided in the feed pump outlet 4 to stop the engine. In another embodiment, the centrifugal governor is omitted and the valve member 22 is moved by the feed pump pressure acting on its inner end against spring 31. In this embodiment, the rod 25 is not axially movable, the slot of the pin and slot connection 26 being extended. A cut-off valve is inserted between the valve member chamber and the feed pump outlet so that when closed, the injection pump delivery pressure moves valve member 22 outwardly sufficiently for all of the delivery to spill into the spring chamber, thereby stopping the engine. Additional means for governing the engine speed may be provided by replacing cut-off valve 41 by a restricted orifice through which spilled fuel from valve chamber 21 flows during the suction stroke, so that the rate of return of valve 22 into chamber 21 is controlled by the size of the restriction and the setting of spring 31. In another embodiment, high pressure spill surges are isolated from the feed pump outlet.

Patent GB-739010-A (GB)
Title: Improvements in and relating to the steering of endless track vehicles
IPC: B64C25/48
Filed: 1953-06-03
Abstract: 739,010. Operating clutches. WESTING- HOUSE BREMSEN-GES. June 3,1953 [June 3, 1952], No. 15314/53. Class 80 (2). [Also in Group XXXI] The invention relates to an endless track vehicle in which compressed air pipes pass from a rotatable superstructure to the lower part of the vehicle through a rotary connection 23, and in which the clutch and brake associated with each endless track are operatively connected to a respective piston 19 slidably mounted in a cylinder 16. According to the invention, pressure variations from the superstructure are arranged to actuate relay valves 25 mounted on the lower part of the vehicle, the valves 25 effecting the connection of the cylinders either with a compressed air container 24, or with the atmosphere. In the construction shown, a main air pressure pipe 22 is connected via the rotary connection 23 to the compressed air container 24. Pressure from the pipe 22 is also fed to one or other of pipes 14, 15, according to the position of a driver's control 13. The pipes 14, 15 are connected via the connection 23 to the respective valves 25, which control the application of pressure from the reservoir 24, to the respective cylinders 16. The arrangement is such that when the handle 12 of the control 13 is in the position shown in full lines, both pipes 14, 15 are isolated from the line 22. Under these conditions, a spring 18 maintains the piston 19 in a position in which the respective clutch is engaged. According to which direction the handle 12 is moved, pressure from line 22 is applied to one or other valve 25, and thus to one or other of cylinders 16. If the handle 12 is moved a limited amount, the respective clutch is disengaged. If the handle 12 is moved further, the clutch remains disengaged, and the respective brake is engaged. A valve 20 interposed in the pipes 14, 15 serves, when set in one position, to short-circuit these pipes, so that pressure from the line 22 is applied to both valves 25, and so to both cylinders 16, simultaneously. In a modification (Fig. 1, not shown), there is no over-riding control valve 20. Also the cylinders 16 are double acting. An additional valve is associated with each valve 25, the result being that pressure is normally applied to the underside of both pistons 16. When the handle 12 is moved in one or other direction from the central position, to a normal operative position, pressure is applied to the upper end of the respective cylinder 16, and the cylinder space on the underside of the piston, is connected to atmosphere. When the handle is moved beyond either normal operative position, pressure is applied to the upper end of both cylinders 16.

Title: Improvements in and relating to the amplification of electric currents
IPC: H04B1/22
Filed: 1919-06-20
Abstract: 151,346. British Thomson-Houston Co., (General Electric Co.). June 20, 1919. Thermionic relays.-Electric valve amplifiers arranged in cascade as described in Specification 129,313, [Class 40 (v), Wireless signalling &c.], have a shunt connexion from plate to filament comprising a condenser in series with a tuned circuit, the potential differences across the tuned circuit being applied to the grid and filament of the succeeding valve. In the example shown, a receiving-aerial 1 is coupled to a secondary circuit 2 connected across the grid and filament of the first valve 3. The plate circuit of this valve includes the battery 7 and resistance 13. A shunt circuit connecting the plate and filament comprises a condenser 17 in series with a circuit 18, 19 tuned to the desired frequency. For currents of the desired frequency, the impedance of the condenser 17 is small compared with that of the tuned circuit, and the greater part of the potential difference between plate and filament is therefore transferred to the grid of the second valve 4, which is connected to a point between the condenser 17 and the tuned circuit 18, 19. For currents not of the desired frequency, a greater proportion of the potential difference will occur across the condenser 17 and will be relatively ineffective on the next valve 4. Similar connexions are made for the succeeding valves, and the shunt circuit for the last valve includes a telephone 24. If continuous waves are employed, the signals are rendered audible by coupling to the shunt circuit a high frequency valve generator 25 arranged to heterodyne with the received waves. The plate circuits of the amplifying. valves are energized by a common battery 7 through resistances 13 - - 16, and the filaments are heated by current supplied by a portion of this battery through adjustable resistances 9 - - 12.

Abstract: 712,561. Batteries. ELECTRIC STORAGE BATTERY CO. June 20, 1952, [Aug. 28, 1951.] No. 15557/52. Class 53. [Also in Group XXII] An electrode consisting of a porous silver salt or oxide has parts of non-porous silver, the whole having been made from porous silver. The electrode is made by impregnating a sheet of paper, cloth or other porous combustible material with silver nitrate and igniting the sheet, the temperature being kept below the melting point of silver. The sheet of porous silver so formed is subjected to pressure in a press so that certain areas such as the lug 11 and bar 13 and strips 14, 15 are compressed to the non- porous form for strengthening the plate and to provide good conducting paths, the greater part, of the plate being subjected to a smaller pressure to maintain it in the porous state. The plate is formed electrolytically in a bath of potassium hydroxide if silver oxide is required as the active material, or in a chloride solution if silver chloride is required. In an alternative construction a grid of magnesium, nickel, steel or other metal is covered on each side with an ignited sheet of porous silver and the whole compressed to force the silver into the grid some parts being simultaneously highly compressed to form the required non-porous areas.

Title: Improvements in or relating to the supply of electrical energy in controlled amounts
IPC: H05B6/04
Filed: 1957-05-16
Abstract: 821,279. Control systems for high-frequency heat treating processes. UGINE-INFRA. May 16, 1957 [May 17, 1956], No. 15588/57. Class 38 (4). An electrical control system for controlling the amount of electrical energy supplied to a load comprises apparatus for continuously deriving an instantaneous voltage which is proportional to the instantaneous rate of supply of energy; integrating this voltage to obtain a voltage proportional to the amount of energy supplied and utilizing this integrated voltage to operate a switch to remove the supply when the desired amount of energy has been supplied. The energy supplied by a source 6 to a load 7 is controlled by two valve amplifiers 2, 3, the voltage gains of which are proportional to the volt drops across resistors 4, 5 respectively, that is the voltage across, and the current taken by, the load 7. The voltage so derived appears across the resistor 10 and is proportional to the instantaneous delivery of power. A condenser 12 is charged from a source 14 under the control of a control device 13 which is itself under the control of the voltage across the resistor 10. The voltage which appears across the condenser 12 is thus proportional to the amount of energy supplied to the load 7 and this voltage is arranged to operate an inertia-less switching arrangement to cut off the supply to the source 6 when the desired amount of energy has been supplied to the load 7.
