Title: Improved manufacture of threads of textile material
IPC: D06B23/08
Filed: 1929-11-25
Abstract: <PICT:0344414/IV/1> <PICT:0344414/IV/2> Threads and fabrics are impregnated with an aqueous dispersion of an elastic or plastic material such as rubber, gutta-percha, balata or the like under a fluid pressure, so that the elementary fibres are bound together and the constituent parts of a twisted or cabled thread are isolated from one another by the impregnating material.  This is effected by placing the threads in contact with the impregnating material for a sufficient length of time, penetration being accelerated by vacuum or pressure or both.  Fig. 1 shows an apparatus for impregnating with the use of increased and diminished pressures.  The vessel a receives the threads which are wound on bobbins d held on the central perforated tube f by means of a clamping device g.  The container b stores the impregnating liquid, and is provided with a gauge glass g1 and a filling vat i.  The two vessels are connected together as shown, and each is connected to a compressed air supply at r and to a vacuum pipe at o.  By manipulating the cocks in suitable succession, the container a is first subjected to diminished pressure, the impregnating liquid is transferred thereto, and compressed air admitted to the space above the liquid.  When impregnation is complete, a vacuum is created in the vessel b and the liquid forced back into it.  By causing vacuum to act in the container a, the bobbins exude the excess of impregnating liquid. The operation may be repeated two or three times.  If desired, the impregnated threads or fabric may be subjected to a further treatment at atmospheric pressure in the apparatus shown in Fig. 2.  The thread 1 coming from the bobbin 2 passes through the brush 3, between the bristles 7 of a brush secured to the hinged cover 8, then through a brush 10, and a brush 12 which reciprocates across the path of the thread, and is finally wound on to the reel 14.  The impregnating liquid is placed in the recess 16.  The thread is passed through several baths in succession, or through the same bath several times.  When rubber latex is used, any suitable substance is added for avoiding premature coagulation. The treated threads may be vulcanized, or woven into fabric and vulcanized.  Fabrics, ribbons, or tapes may be treated in the same manner.

Title: Nuclear reactor
IPC: G21C5/06
Filed: 1975-09-03
Abstract: 1505576 Reactors WESTINGHOUSE ELECTRIC CORP 3 Sept 1975 [13 Sept 1974] 36208/75 Heading G6C A nuclear reactor, particularly a liquid-metal cooled, fast breeder reactor has upper internals which include provision for channelling the coolant flowing from the core-component assemblies to the outlet plenum in vertical paths in direction generally along the direction of the respective assemblies. The coolant is channelled by a plurality of chimneys 140, 142, each secured to, and extending from, a grid 138 through whose openings 136 the coolant emitted by a plurality of core-component assemblies encompassed by the grid flows. To reduce the stresses resulting from structural interaction, or the transmission of thermal strains due to large temperature differences in the coolant emitted from neighbouring core-component assemblies, throughout the chimneys 140, 142 and the other components of the upper internals, the grids 138 and the chimneys 140, 142 are supported from the head plate (41) and the core barrel (118) by support columns (75) (Figs. 1A, 1B, not shown) which are secured to the head plate at the top and to a member, which supports the grids and is keyed to the core barrel, at the bottom. In addition to being restrained from lateral flow by the chimneys 140, 142, the coolant is also restrained from flowing laterally by a peripheral seal (282) (Fig. 19, not shown) around the top of the core (93). The chimneys 140, 142 and the grids 138 are formed of a highly-refractory, high corrosionresistant niokel-chromium-iron alloy which can withstand the stresses produced by temperature differences in the coolant. The chimneys 140, 142 are supported by pairs of plates 165, 167 and 169, 171, each pair held together by hollow stubs 175 coaxial with, and encircling, the chimneys. The plates 165 to 171 and stubs 175 are a welded structure but, in the interest of economy, are composed of stainless steel which is not weld compatible with the refractory metal. The chimneys 140, 142 and the stubs 175 are secured together by shells 214 of another nickel-chromium-iron alloy which is weld compatible with, and is welded to, the stubs 175 and has about the same coefficient of thermal expansion as the highly-refractory, high corrosion-resistant alloy.

Abstract: 800,511. Gas turbine plant. NAPIER & SON, Ltd., D. Nov. 18, 1955 [Dec. 14, 1954], No. 36235/54. Class 110 (3). [Also in Group XXIX] Associated with the delivery passage 6 of the fuel pump 1 is a subsidiary metering device comprising a piston 93 embodying a metering orifice 94, the pressure drop across which is maintained constant by a piston valve 95 acted upon by the rod 96 of the piston 93 and a spring 97, the valve controlling the fuel inlet to the underside of the piston 93; the pressure drop across the orifice can be varied by an adjustable spring 98. The fuel from the orifice 94 flows to both the servo piston 49 connected to the sleeve 11 of the main metering orifice 13 through which fuel is supplied to the fuel nozzles, and to the servo piston 83 which controls the incident angle of the compressor inlet guide vanes, not shown. If neither of these servo devices is in operation the fuel will flow to a relief passage 101 via a relief valve 100 and the arrangement is such that the volumetric rate of flow through the main orifice 13 is unaffected when either of these servo devices is in operation. Temperature responsive devices 115, 116 subject to the temperature in the combustion chambers or at points in the path of the combustion products act through levers 117, 118 on relief valves 120, 121 controlling ports in the passages 9 and 27 to reduce the delivery of the pump 1 above a given temperature. The emergency control lever 107 operates a turbine brake 112 as well as the dump valve 114 and governor override. The subject-matter of this Specification is otherwise substantially the same as that described in Specification 790,052.
