Filed: 1959-02-27
Abstract: 886,834. Attaching bail handles. WILKIE & PAUL Ltd. Jan. 5, 1960 [Feb. 27, 1959], No. 6814/59. Class 83 (2). A method of attaching a bail to a canister comprises forming a re-entrant in the wall of the canister at two opposite points or at corresponding points in a blank which will be formed into a canister, inserting into each a bail mounting attachment and deforming the attachment or the canister to prevent separation. A cavity wherein the mouth 13 is smaller in circumference than the base 14 is formed with a central dish 15 and a bail mounting which has a bead 18 and an aperture 20 for the bail is placed in the cavity. The mounting which may be made of thermo-plastic material melts at a lower temperature than the canister and is heated to cause it to flow as shown in Fig. 4. Alternatively or additionally the lip 13 may be pressed into contact with the base of the mounting. In a modification (Figs. 7 and 8) the cavity has no central dish and the bail mounting comprises a peg 22.

Title: Improvements in means for producing light of rapidly controllable intensity
IPC: H05B41/232
Filed: 1938-03-04
Abstract: 506,690. Discharge lamps; light valves. GENERAL ELECTRIC CO., Ltd. (Patent- Treuhand-Ges. f³r Elektrische Gl³hlampen) March 4, 1938, No. 6830. [Classes 39 (i) and 40 (iii)] Means for producing a beam of light of rapidly controllable intensity comprises a highpressure metal vapour lamp having more than two electrodes arranged in a single envelope so that a discharge column can be transferred from one pair of electrodes to another, one or more sources of electrical supply, means for varying rapidly the voltage applied by the sources to at least one pair of electrodes, optical projecting means for forming a beam of light from the lamp, and screens so associated with the lamp and projecting means that a change in the spatial distribution of the light in the source resulting from transference of a discharge produces a change in the intensity of the beam. In the form shown, two diagonally disposed pairs of electrodes 4, 6 and 5, 7 have separate sources 15, 16 of direct voltage. If the voltage of 15 is kept constant and that of 16 is increased from zero the initial discharge between 4 and 6 will be supplemented by subsidiary discharges between 5 and 6, and between 4 and 7 ; these discharges will grow in intensity until finally that between 4 and 6 disappears. Thus, if the image of the source be focused on a screen which permits only light from the centre to pass, there will be a continuous decrease in intensity of the beam. The filling is mercury at a working pressure of 20 atmospheres. A single electrode may be common to two pairs. In another method, the two sources generate alternating voltages of equal intensity, frequency and wave-form but their phase difference is varied, giving again a variation in intensity between the centre and edges. The light from the edges and from the centre of the beam may be separated and directed to different receivers, to give a push-pull effect. Specifications 476,818 and 486,768 are referred to.

Filed: 1964-02-19
Abstract: 1,046,552. Steam traps &c. BADISCHE ANILIN- & SODA-FABRIK A.G. Feb. 19, 1964 [Feb. 20, 1963], No. 6879/64. Heading F4U. A thermally controlled condensate discharger comprises thermal bimetallic control means controlling a valve having a stem 11 and having a plate 15 on the outlet side of the valve seating 22 of valve body 4, which plate forms a gap 23 with valve body 4, the diameter of the plate being at least twice that of the valve passage 12. Condensate and steam pass through passage 7, chamber 9 enclosing the bimetallic plates, passages 10, 11, 12 in the valve body and out through chamber 20 adjacent the plate 15 and outlet 21. The valve is opened by the temperature effect on the bimetallic plates 17 and pressure in chamber 9. As condensate passes through the gap between valve plate and body the change of pressure causes the formation of steam in the gap which assists opening. The plate and stem may be joined by a conical part, the plate and seating may have curved surfaces and the gap may widen outwardly.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T8/18
Filed: 1926-03-12
Abstract: 251,243. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Compagnie des Freins Westinghouse). April 21, 1925, [Convention date]. Fluid - pressure. - Fluid-pressure braking- apparatus for railway vehicles comprises a distributing valve de.- vice adapted to supply fluid under pressure in separate stages to effect an application of the brakes in which the transition from one stage to another is utilized to effect an increased braking action on a loaded vehicle. For braking a loaded vehicle there are provided a supplementary brake cylinder 6, Fig. 1, adapted to actuate a lever 7, connected to the brake gear by a bar 8, and a supplementary reservoir 9 of small capacity in addition to the usual auxiliary reservoir 4. In Fig. 2, which shows the modification in the distributing valve, passages 15, 16 correspond respectively to the exhaust and inlet ports of the triple valve. Passages 17, 18 communicate respectively with the usual brake cylinder 3, Fig. 1, and the supplementary brake cylinder 6. The usual check-valve 21, Fig. 2, is provided with a valve 23 held on a seat 24 by a spring 25, and a cock 27 is adapted to be rotated in a casing 34. In braking a loaded vehicle, pressure fluid flows from reservoirs 4, 9, Fig. 1, through port 16, a passage 39, a chamber 40, past the open check-valve 21, and through a port 26 and the passage 17 to the brake cylinder 3. The fluid can flow from passage 17 through passages 19, 20, a port 36 in the casing 34, a cavity 29, and a port 30 in the cock 27, shown at 14 in Fig. 1, but cannot flow to the supplementary brakecylinder passage 18 by reason of a ball valve 32 closing a port 31, a cavity 28, and a port 38. When the piston of the usual cylinder has completed its stroke and the valve 21 descends, the supplementary cylinder is supplied with fluid through a port 35, the, cavity 28, and the passage 18. The cylinder 3 is exhausted through passages 17, 19, 20 and through ports in the cock 27 and casing 34 to the passage 15. and the cylinder 6 through ports 28, 31, 30, 37 to the passage 15. The ports 26. 35. 36, 37 are calibrated to ensure charging and exhausting of the brake cylinders in equal time for light and load braking. In light braking the reservoir 9 is empty and the cylinder 6 does not come into action. In load braking after automatic or other movement of a cock 13, Fig. 1, connecting the supplementary reservoir 9 to the usual auxiliary reservoir 4, pressure fluid flows from these reservoirs rapidly into the usual brake cylinder 3 and ensures a rapid displacement of the brake gear. When this displacement is effected, the triple valve 1 ensures a regulated supply of fluid to the cylinder 6. The piston 10 of the cylinder 6 is connected to the stem 11 by a ratchet or clutch device so that when fluid is supplied to the cylinder 3, the piston 10 is not displaced. The cock 13 is connected to the cock 14 of the triple valve, but may be operated independently thereof, or the cock14 may control communication between the reservoirs 4 and 9.

Title: Reaction propulsion system
IPC: F02K7/08
Filed: 1948-03-05
Abstract: A rocket-like body is propelled by a reaction jet produced by burning fuel with atmospheric air and a nitro-aliphatic oxidant. The oxidant decomposes at a relatively low temperature and provides nascent oxygen which accelerates the combustion of the fuel with the atmospheric air.  The fuel may be made up of one or more members of the paraffin hydrocarbon series and preferably will comprise either kerosene or gasoline.  Nitro-aliphatic oxidants mentioned are nitromethane, tetranitromethane, nitroethane, hexanitroethane, 1-nitropropane, 2-nitropropane, 1, 1-dinitropropane, 2, 2-dinitropropane, 1, 2-dinitropropane, 1, 3-dinitropropane, 1, 1-dinitroethane, 1, 1, 1-trinitropropane, and 1, 2, 3-trinitropropane.  Fuel and oxidant are mixed prior to being injected into the combustion chamber of a ram-jet tube.  The mixture is varied with altitude by pressure-responsive devices which reduce the feed of fuel and increase the feed of oxidant as the altitude increases.

Title: Improvements in and relating to treatment of soap particles
IPC: C11D9/10
Filed: 1952-03-18
Abstract: "Balling" in powdered soap compositions containing silicate solids is reduced by applying to the particles at least 1 per cent. by weight of fatty acid having from 8 to 14 carbon atoms in the molecule, and reacting the fatty acid in fluid condition with silicate solids at the surface of the particles.  The resistance to "balling" is effected by a thin crust on the particles comprising a coconut-oil type of soap and silicate complex.  A single fatty acid, such as capric acid, may be used or a mixture of fatty acids derived from an oil of the coconut - oil group such as oils of tangkellak kernel, ucahuba nut, jaboty kernel, khakan kernel, coconut, muru-muru kernel, tucuma kernel, cohune nut, ouricoury nut, babassu kernel and palm kernel.  The fatty acids may also include synthetic fatty acids prepared by oxidation of petroleum or by hydrogenation of carbon monoxide by the Fischer-Tropsch process.  From 2 to 5 per cent. of the fatty acid is preferred.  The fatty acids may be sprayed on to the particles while the latter are agitated or the particles may be passed through a mist of the fatty acids.  The fatty acids should be in a fluid condition, such as heated to liquefy them or in solution in a solvent, e.g. ethyl alcohol.  The temperature of the particles during spraying is preferably 50 to 115 DEG F.  The moisture content of the particles is preferably within a range of 4 to 20 per cent. The compositions treated may comprise silicate-containing ground soap flakes, chips, threads or granules.  The soap compositions contain at least 1.5 per cent. by weight of the silicate solids, which may be derived from a wide variety of water-soluble silicates.  Sodium silicates of SiO2 to Na2O ratios varying from 2.0 to 1 to 4.0 to 1 are preferred. A maximum of 50 per cent. of the silicate solids is specified. The silicates may be mixed with an alkaline material such as caustic soda or soda ash.  The compositions may contain other builders such as soluble pyrophosphates, orthophosphates, tripolyphosphates and borates.
