Title: Apparatus for installing and removing flow control device
IPC: E21B23/10
Filed: 1975-03-21
Abstract: 1491626 Wells &c. CAMCO INC 21 March 1975 [29 March 1974] 11960/75 Heading E1F To enable a kick-over tool, used for placing a flow control device 18 in a selected offset pocket in a mandrel 12 to move through curved well tubing the tool body 30, 34 is articulated. The articulation is provided by a ball and socket joint 80 which has a pin and slot arrangement to constrain the pivotal movement. The flow control device is supported on an arm 32 pivoted to a guide portion 34 of the body, the arm being releasably held adjacent the guide portion until the tool is orientated in a desired position, when correctly orientated the arm is released and biased away from the guide portion and towards the pocket by means of a spring 40. Orientation of the tool is achieved by means of a spring-biased key 52 which engages a guide surface (26) Fig. 4 (not shown) and subsequently a guideslot (24) of an orientating sleeve 22 in the mandrel. When the key is engaged in the slot an upward pull on the tool causes an actuator to release the arm, the actuator passing through the centre of the ball and socket joint 80.

Title: Composite materials comprising resin and carbon fibres
IPC: D01F9/12
Filed: 1972-03-15
Abstract: 1383212 Carbon fibre composites COMMISSARIAT A L'ENERGIE ATOMIQUE 15 March 1972 [19 March 1971] 11982/72 Heading C1A [Also in Division C3]  A composite material comprising carbon fibres and resin is prepared by (a) treating carbon fibres with a homopolymer or an alternating copolymer, or the monomer(s) thereof, so as to chemically bond the homopolymer or copolymer to the fibres, and (b) incorporating the fibres with the homopolymer or copolymer chemically bonded thereto in a resin which is compatible with the homopolymer or copolymer. The polymer may be bonded by covalent bonds formed by radical grafting or anionic grafting or be bonded by hydrogen bonds, dipole-dipole bonds or saline bonds. In Eamples 1 and 2, maleic anhydride and styrene were radically grafted on to carbon fibres, the polymerization being thermally initiated. The fibres were then treated with a polyester resin and incorporated into a polyester resin, and the composite material allowed to harden in a mould. In Example 3, air-oxidized carbon fibres were dipped in a solution of maleic anhydride-styrene copolymer, incorporated into an epoxy resin after preimpregnation in a solution of resin, and hardened and moulded. In Examples 4 to 8 air-oxidized carbon fibres were salified with NaOH and immersed in a solution of a maleic anhydridestyrene or maleic anhydride-ethylene copolymer which had previously been salified with NaOH. The fibres are incorporated into epoxy and polyimide resin. Example 9 air-oxidized carbon fibres which had been refluxed with calcium acetate were immersed in an NaOH salified maleic anhydride-styrene copolymer solution, and the fibres incorporated into an epoxy resin. In Example 10, air-oxidized carbon fibres are immersed in a polyvinyl-4-pyridine solution and incorporated in a polyester resin. Graphitized fibres may be similarly treated.

Title: Improvements in light projectors more particularly adaptable for headlamps of vehicles and the like
IPC: F21V7/00
Filed: 1920-05-03
Abstract: 142,812. Balsillie, J. G. Oct. 7, 1919, [Convention date]. Vehicular and like lanterns.-In vehicular headlights and other light projectors, reflectors are employed which produce a beam of elliptical cross-section, whose major axis is, in the case of headlights, horizontal. The reflector has a reflecting-surface of such configuration that the meridianal curves are of gradating focal length, and consist of segments of parabolas, &c. The gradations may be in arithmetic or logarithmic progression. In the form shown in Fig. 6, the rim A<2> of the reflector A has a circular periphery so that it is adapted to fit the ordinary parabolic reflector D of a lantern, and the socket for the burner or electric lamp-holder is concentric with the circular periphery of the rim A<2> but eccentric with the elliptical opening in the reflector, so that the light beam is projected in a downwardly inclined direction. The reflector A may be mounted on an auxiliary electric lamp-holder B, which fits the ordinary electric lamp-holder C. A hemispherical reflector H may be mounted in front of the source of light to intercept direct light rays, and the part of the ordinary parabolic reflector D not covered by the reflector A is painted a dull black. The Specification as open to inspection under Sect, 91 (3) (a) states that the reflector may consist of segments of circles, ellipses, cycloids, &c., or a combination of curves, and the beam may be produced by lenses, or a combination of lenses and reflectors, such as a convex cylindrical lens with or without a spherical lens or reflector. A convex cylindrical lens may replace the hemispherical reflector H. Fig. 8 (Cancelled) shows a lantern in which a convex cylindrical lens L is arranged in front of, and a hemispherical reflector M behind a light source E arranged at the common focus of the reflector M and the lens L. The back of the lens L may be stepped or frosted. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 156,285.

[Class 39 (i)] The material used to form a luminescent screen comprises a combination of cadmium oxide, magnesium oxide, a manganese activator and either or both of silicon and germanium dioxide; to this may be added either or both of zinc or beryllium dioxide. The relative proportions of magnesium to cadmium are given and also the amount of dioxides to form the orthosilicate of magnesium or the meta-silicate of cadmium or the germanates of these bases or the orthosilicates or germanates of zinc or beryllium if these are present. To form the material to suitable suspensions of silicon dioxide and for germanium dioxide are added soluble salts such as the nitrates of magnesium and cadmium with or without the zinc and/or beryllium salts and ammonium carbonate; a specified amount of manganese nitrate is also added, the solid particles formed being heated at between 700‹-1600‹ C. for about one hour. The manganese salt may be added after the other materials have been comboned and distilled water added to make these materials wet, more ammonium carbonate being used to precipitate the manganese. The silica may be ground to pass through a 400-mesh screen. The material without zinc or beryllium gives a warm cream colour for use in reception halls &c. The spectral emission can be controlled by varying the amount of manganese, the temperature at which the material is treated or by high temperature quenching as described in the U.S.A. Specification 2,129,096 ; emission at infrared may be attained. Small amounts of barium strontium, calcium caesium, ruabidium, lanthanum, cerium, thorium or their compounds may be added to improve the secondary emission. Screens may be used with cathode rays. U.V., radio-active emanations and X-ray. Specification 512,154 is referred to.

Abstract: 125,300. Renold, Ltd., H., and Herford, R. O. Aug. 2, 1918. Driving-chains with separate joint pins.-A locking- plate f for engaging with grooves in the studs of driving-chains to retain a detachable link-plate in position has a forked end g and an arched end h adapted to be engaged with their corresponding grooves by a longitudinal sliding movement of the plate, the end h being formed by an aperture opening into a larger aperture through which the end of the stud can be passed, in doing which the stud engages the head m of a spring tongue l and presses this out away from the side of the chain link, and when the plate is slid into locking position, the tongue m clears the stud and snaps back, thereafter preventing movement of the plate. To release the plate, the tongue must first be raised clear of the end of the stud; this may be done by inserting a hooked lever in an aperture o, or by inserting a screwdriver beneath it through an aperture which may be provided and bounded by a line u, or by other means. A raised projection v on the tongue prevents this from slipping into the groove in the stud.
