Title: Fuel injection arrangement for gas turbine engines
IPC: F02C7/22
Filed: 1961-06-08
Abstract: 915,233. Gas turbine jet engines. UNITED AIRCRAFT CORPORATION. June 8, 1961 [July 13, 1960], No. 20841/61. Class 110 (3). In a gas turbine engine comprising concentric inner, middle and outer walls defining inner and outer air passages, a fuel injection arrangement comprises a hollow ring member which is detachably mounted at the upstream end of the middle wall, the ring member being formed by a plurality of fuel manifold arcuate sections which are readily detachable from one another, and are supported by hollow radial bosses through which fuel is supplied to circumferentiallyextending conduits in the manifold sections. Fuel is adapted to be discharged from the manifold sections into the inner air passage. The supporting bosses are slidably supported by the outer wall so as to permit thermal expansion of the middle wall relatively thereto. The invention is described with reference to a gas turbine jet engine of the by-pass type, as shown in Fig. 1. The by-pass passage 24 is formed by the inner wall 26 and by an outer wall 36 and a middle wall or baffle 40 is disposed therebetween so as to define an inner air-fuel passage 42 and an outer cooling air passage 44, a fuel supply apparatus 50 being mounted at the upstream end of the middle wall. The apparatus 50 is shown in Fig. 2 and comprises a hollow ring member 66 within which are disposed two fuel manifold rings 70, 72 which are connected to members 74. Fuel spray bars 76 having discharge orifices 96 are mounted on the members 74. Fuel is supplied to the manifolds 70, 72 through members 100, 102 which also serve to support the manifold rings from the outer wall or casing 36, the fuel passing from the manifolds through ducts 86, 88 into the spray bars. The fuel supply and support boss 106 shown in Fig. 6 passes freely through an opening 116 in a plate member 110 secured to the engine outer casing 36. There may be three arcuate sections 118 of the ring manifold each extending 120 degrees and supported at its mid-point by a support boss 106 and secured at its ends to the ends of the adjacent manifold sections as shown in Fig. 7. Adjacent ends of the sections 118 are secured to members 122, 124 which overlap and are connected together by bolt members 130 as shown in Fig. 10. The ends of the fuel conduits 70, 72 in each arcuate section 118 are closed by means of plugs 132, Fig. 9, so that fuel does not pass between the manifold sections.

Abstract: 1,008,341. Coating apparatus. WOOL INDUSTRIES RESEARCH ASSOCIATION. May 19, 1964 [May 25, 1963], No. 20985/63. Heading B2B.  A jointing &c. dispenser includes a container for the jointing preparation, a lid or cover  therefor with an opening in it, and a roller segment rotatably mounted in the container and arranged to be rotated with the segment submerging so that it picks up jointing preparation, a scraper device arranged to operate on the part-circumferential surface of the roller segment to remove surplus preparation therefrom, the roller segment having on its surface helical or other grooves or depressions or cavities, whereby the quantity of jointing preparation dispersed at each revolution of the roller segment can be accurately controlled. In the arrangement shown, a container 1 has slots 3 in its sides to receive the two ends of axle 4 of a roller segment 5 and also to locate the lid or cover 6. The cover 6 has a slot 13 therein for the roller segment 5 and carries a scraper blade 12 which can be adjusted in position thereon relative to the roller segment 5. The segment 5 may be grooved helically or with grooves inclined to the axis of rotation or it may have a transverse channel or be plane and covered with a gauze or other perforated or reticulated cover. In operation axle 4 is rotated and roller segment 5 picks up jointing preparation 15 and transfers it to the outside of the container for application to any desired surface. Due to the surface formation of roller segment 5 and the wiping action of blade 12 an accurately controlled amount of jointing preparation is conveyed thereon.

IPC: C01B17/86
Filed: 1927-08-15
Abstract: 276,659. Petersen, H. Aug. 28, 1926, [Convention date]. Tower processes.-In the manufacture of sulphuric acid by tower processes, such as the Opl process, sufficient nitrogen oxides are set free in the first production tower to oxidize the sulphur dioxide in all the later towers. This is accomplished by the use of a tower of large dimensions irrigated intensively with nitrated acid. The tower may be fitted with atomizers, washers, rotary mixing-devices; &c. or may be packed with acid-resisting grains having a diameter of about 40 mms. An amount of acid representing the production capacity of the plant is withdrawn from the base of the tower and the remainder is passed into the last tower and recirculated through the towers.

Title: Improved method of treating polymeric vinylidene chloride
IPC: C08J3/00
Filed: 1939-07-26
Abstract: 532,697. Vinyl polymerization products, artificial filaments and films. TENNANT, W. J. (Dow Chemical Co.). July 26, 1939, No. 21734. [Classes 2 '(ii) and 2 (iii)] To improve the strength of polyvinylidene chloride and to facilitate the fabrication thereof into articles of high strength by coldworking methods, the polymer or a crystalline co-polymer thereof is heated to a temperature between the softening point and the decomposition temperature until thoroughly plastic, and is then rapidly cooled to about room temperature. For a short period after this treatment, usually from 2 to 60 minutes, the product can be readily cold-worked, e.g. by rolling, extruding, drawing or cold moulding ; when the articles produced are films, filaments, threads or other articles having at least one major dimension of relatively great length as compared with at least one minor dimension of relatively small thickness, it is found that they exhibit a crystalline X-ray diffraction pattern showing the polymer molecules to be orientated parallel to one another and to the major dimension of the article, and that they have a high degree of flexibility and tensile strength. In examples : (1) polyvinylidene chloride, (2) a co-polymer of vinylidene chloride and styrene and (3) a co-polymer of vinylidene chloride and ethyl acrylate are heated to above the softening point until plastic, and then rapidly cooled to form products which are rapidly moulded in the cold ; (4) a co-polymer of vinylidene chloride and vinyl chloride plasticized with phenoxy-propylene oxide is moulded while hot to a sheet; the sheet is cooled, dipped into heated glycerine, and then chilled in water; (5) vinylidene chloride polymerized by heat in the presence of hexachlorodiphenyl oxide and benzoyl peroxide is dissolved in o-dichlorobenzene and cast to a film on a magnesium plate ; before removal from the plate, the film is dipped into heated glycerine and then chilled by dipping in water ; (6) polyvinylidene chloride is melted, rapidly cooled to room temperature, and stretched to produce tough pliable fibres ; (7) a co-polymer of vinylidene chloride and vinyl chloride plasticized with tricresyl phosphate is heated and extruded while hot to produce a filament which is passed directly into cool water, the cooled filament being then stretched at room temperature to produce a filament from which fishing nets and filter cloths can be made ; (8) a co-polymer of vinylidene chloride and vinyl acetate is heated in the presence of dioxan and the hot gelatinous mass extruded ; the fibre produced, freed from dioxan by a current of hot air, is heated by immersion in hot glycerine and then cooled to produce a fibre resembling silk ; (9) and (10) co-polymers of vinylidene chloride with styrene or ethyl acrylate are softened in a heated glycerine bath and then subjected to rapid drawing and simultaneous cooling in air to produce tough filaments.
