Abstract: 1,243,231. Valves. J. PAUSCH. 29 July, 1968 [3 Aug., 1967], No. 36001/68. Heading F2V. [Also in Divisions B1-B2] Inward-flow cloth filter bags (16) discharge into various spaces 18, each of which opens into a common discharge chamber through an aperture 26, and the bags connected to a particular space 18 are cleaned by reverse flow when a valve 28 is raised to close aperture 26 and actuates a pneumatic trigger 62, which causes rapid opening of two valves 60 to direct a burst of compressed air from reservoir 44 into space 18 and outwards through the bags. The compressed air supply to reservoir 44 also raises the various valves 28 in sequence as controlled by an electric timer. Valve 28 lifts spring-loaded plunger 98 of trigger 62 (Fig. 5, not shown), releasing the pressure on the upper sides of the diaphragms of respective valves 60 (Fig. 4, not shown), which diaphragms then rise quickly to allow compressed air into space 18. The filter operates under suction.

Abstract: 762,196. Rotary unions for pipes. MURRAY, W. March 17, 1955 [Dec. 30, 1953], No. 36229/53. Class 99(1) In a rotary union comprising relatively rotatable fluid-conveying members 1, 2 one of which is supported with respect to the other in one or more ball or roller bearings 5, or both, of carbon bearings, and a rotary sliding contact seal including a floating element which is pressed towards a co-operating element on the member 2 and is sealed to the member 1, there is a resilient sealing ring 22 between the element and the member 1, the ring being constructed and arranged to press against the member and the element with a pressure which increases with the fluid pressure, and the element being responsive to the fluid pressure acting against the pressure by which the sealing ring is forced against the element. As shown, the floating element, of close-grained cast iron or carbon, comprises a sleeve 19 surrounding and axially displaceable along the shaft 2, and a collar 18 provided with an axially projecting ring 21 on which a sealing face 20 is formed by lapping. The face 20 contacts a sealing face 17 on the collar 16 provided on the shaft 2 which may be nitrided or of nitralloy. The ring 22 is U-shaped in section and of natural or synthetic rubber or other resilient material and the inner and outer walls of the ring are arranged to be forced against the outer surface of the sleeve 19 and the inner surface of the body 1; the inner surfaces of the walls of the ring diverge from the base 23. A spring 27 is disposed between a spreader ring 24, having converging peripheral faces 25, 26, and the collar 18 to urge the faces 17, 20 into contact and the ring 24 between the walls of the ring 22. The pressure fluid conveyed by the union urges the ring 24 towards the base 23 of the ring 22 and acts behind the collar 18 to urge the latter towards the collar 16 on the shaft 2. Ambient pressure acts of the face 28 of the collar 18 and the area of the collar exposed to the fluid is appropriately chosen to ensure a desired difference in pressure on the opposite sides of the collar. The bearings 5 are spaced by a lantern ring 7 and a ring 6 held in position by a circlip 14 engaging in a groove 15 in the shaft 2, and are lubricated by way of a grease nipple 8. A plug 9 screwed into the body 1 fixes the bearings axially, the inner bearing lying against a plug 10 screwed into the body and abutting a washer 11 and " O " ring 12 which lies against an internal shoulder 13 of the body and prevents fluid leakage along the screw-threads of the plug 10. The shaft 2 has a screw-threaded end 5a for connection to a steam delivery pipe and a pipe for withdrawing condensate from a hollow roll may extend through the shaft. The body 1 may be non-rotatably mounted, yieldingly or otherwise; alternatively the body may rotate and the shaft be yieldingly or otherwise non-rotatably mounted.

Title: Control of fuel injection in internal combustion engines
IPC: F02D41/20
Filed: 1975-09-08
Abstract: 1479806 Transistor switching circuits BEGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 8 Sept 1975 [9 Sept 1974] 36893/75 Heading H3T In a method of controlling an electromagnetic fuel injector in an I.C. engine, errors due to variation of battery voltage are minimized by ensuring that the build-up of current in the injector operating coil occupies a fixed time. This is achieved by charging a capacitor 12 with a constant current to a predetermined voltage, comparing the voltage across the capacitor 12 with a voltage proportional to the coil current and using the resultant to control the build-up time of the coil current. The invention is applicable to a system in which the amount of fuel injected is proportional to the time the injector valve is open. Transistor 10 is normally saturated so that C 12 is discharged. When fuel is to be injected, a positive pulse at A turns on transistor 1 and thus turns off transistors 5 and 10, allowing C 12 to charge with a constant current determined by transistors 13, 16 and Zener diode 15. The voltage at B falls linearly until limited by Zener diode 11. This action allows comparator 19 to turn on transistors 20 and 22, which admit current to the injector coil 23, the current being monitored by resistor 24 and fed back to the comparator 19 so that the build-up of current follows the fall in voltage at B and thus ensures that the build-up time is independent of the voltage of battery 3. A pre-magnetizing current may be applied to coil 23.
