Title: Packing assemblies
IPC: F16L17/035
Filed: 1958-03-18
Abstract: 837,583. Joint-making packings. MISSION MANUFACTURING CO. March 18, 1958 [Sept. 3, 1957], No. 8728/58. Class 122 (3). A packing assembly for sealing the annular space between two parts, such as a cylinder liner 10, Figs. 2 and 3, and a body 11 of a pump, comprises an annular elastic sealing element 12 and deformable back-up rings 13, 14 abutting the ends of the element, each ring having lips 13, 13a and 14, 14a respectively directed towards the sealing element. The sealing element 12, which may be of rubber, is formed with tapered ends, which, as shown in Fig. 3 in undeformed state, abut the curved surfaces 13c, 14c between the lips of the back-up rings 13, 14. The rings 13, 14, which may be of plastic such as nylon and have a small clearance between the walls of the liner 10 and body 11, are arranged so that, when an axial force is applied to the liner, the element 12 is deformed and thereby causes the expanded rubber to act upon the lips and force them into firm contact with the adjacent walls; upon continued pressure on the liner, the element is expanded to completely fill the space between the lips and so make sealing engagement with the walls. As shown in Fig. 2, two packing assemblies are mounted between shoulders 11b, 20 on the pump body 11 and liner 10 respectively and are separated by a non-deformable ring 25 which acts as a support for the plastic back-up rings 13, 14; a hole 27 in the ring leads to an opening 28 for the purpose of detecting leakage. Metal rings 24 may be provided between the back-up rings 13, 14 and the shoulders 11b 20 to provide adequate support should wear occur. The support rings may be moulded or otherwise attached to the back-up rings and in the modification shown in Fig. 12, the element 12 is moulded to the backup rings in which case recesses 112a, 112b are provided in the element to assure that the lips contact the walls before the final sealing engagement therewith of the element. In further modifications, the tapered ends of the element may be flattened or radiused to cooperate with corresponding shapes between the lips of the back-up rings.

Filed: 1950-04-06
Abstract: 679,219. Vehicle headlights; incandescent lamps. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 6, 1950 [April 13, 1949], No. 8764/50. Classes 39(ii) and 75(iv) In an electric incandescent lamp 3 comprising a filament 5 and a screen 6 inside the bulb adapted to prevent radiation of light from the filament to one-half of the space surrounding the lamp an outer corrector screen 13 in the form of an opaque strip covers the bulb where the latter is intersected by the plane through the filament and the edge of the inner screen 6, or in a projector lamp, such as a vehicle headlight, having an incandescent lamp with a filament in a non-focal position in a reflector and a screen inside the bulb for preventing escape of light to one-half of the space around the lamp an outer corrector-screen prevents escape of light in the plane passing through the edge of the inner screen and the filament; the outer correctorscreen in both cases corrects any maladjustment in the relative positions of inner screen and filament. The latter alternative form of the invention is exemplified by a headlight comprising a reflector, a front glass and an incandescent lamp with an unscreened filament at the focus of the reflector and a screened filament in a non-focal position to give a dipped beam, and the outer corrector-screen is constituted by either an opaque strip applied to the front glass or a non-reflecting strip applied to the reflector along a horizontal meridian. The incandescent lamp 3 exemplifying the first form of the invention is fitted into the reflector 1 of a headlight so that the main filament 4 is at the focus and the screened filament 5 is in front of the focus and above the reflector axis. The corrector-screen 13 is formed by covering the bulb with a stencil and spraying with paint or lacquer or by sticking a strip of opaque material to the bulb or by soldering the ends of a metal strip curved around the bulb to the bulb cap 14 or to the reflector; the width of the corrector-screen preferably does not exceed one-fifth or one-tenth of its spacing from the filament. The part of the corrector-screen which intercepts forwardly-directed non-reflected light may be omitted. A ring for attaching the bulb to its holder is positioned accurately relative to the filaments and then soldered to the bulb cap.

Abstract: 945,165. Fluid-pressure servomotor systems. BORG-WARNER CORPORATION. March 14, 1960 [ March 26, 1959], No. 8911/60. Heading G3P. [ Also in Division F1] The control rod 25, Fig. 1, of a fuel injection pump is controlled by intake manifold suction acting through pipe 62 on a diaphragm 83, Fig. 2, the suction being modified at low temperatures by an air bleed 65 to the suction chamber 83 controlled by temperature responsive means 13. The air bleed valve 177, Fig. 4, is controlled by the choke valve thermostat 171 which raises the valve 177 off its seat 183 at low temperatures to open an air bleed passage 186 to the passage 65 leading to the suction responsive device 83, thereby reducing the suction and increasing the fuel supply. The intake manifold suction also acts upon a piston 178 attached to the valve 177 to reduce the air bleed at high load. The diaphragm 83 is connected to cam 80 which operates the pump control rod 25 through a follower 98. The cam 80 is pivoted at 93 on an adjustable stop lever 104 and at 94 on a lever 108 adjusted by a cam rod 110 controlled by a barometric capsule 121. The capsule 121 operates rod 110 through a servomotor comprising a pair of opposed diaphragms 122, 123, subjected to suction through orifice 71. The capsule 121 controls through a lever 130 a slide valve 152 which admits air to one or other chamber 140a, 141a, to reduce the suction on one diaphragm and hence cause axial movement of the rod 110 to adjust the fuel supply through the lever 108. The capsule 121 is carried by a follow up lever 127 which returns the valve 152 to its inoperative position after an adjustment. The injection pump 10 is fed through a pipe 20, part of the supply flowing to a pipe 27 connected to a cold start enriching device 14 operated by a solenoid 153 in the starting motor circuit. The solenoid 14 opens valve 54 to allow fuel to flow from pipe 56 to spray orifices 58 in the intake pipe. The flow to the device 14 may be controlled by a valve 47 operated by a thermostat 44. The intake pipe includes a pair of throttles 163, 164, with the throttle levers 201, 203, interconnected through a lost motion spring 209 and links 202,211. A fast idling stop 204 is controlled from the choke valve lever 205 and a normally open switch 230 in the circuit of the extra fuel device 14 is closed by a cam 206 when the choke 162 is closed. A second switch 231 is opened by the throttle control rod 207 at full throttle for deflooding.
