Title: Improvements in coupling means
IPC: F16L21/02
Filed: 1946-10-10
Abstract: 638,000. Handle fixings. KEESEAL PTY., Ltd. Oct. 10, 1946, No. 30328. Convention date, Nov. 19, 1945. [Class 61 (i)] [Also in Group XXVIII] A resilient sleeve 9 is compressed on assembly between a spigot 8 and a socket 3 and into a groove near the end of the socket bore, the thickness of the sleeve being greater than but not more than twice the difference between the radii of the spigot and bore of the socket. The socket may have an internal flange 4, and the sleeve may be lubricated by applying a light vegetable oil. The socket may be in the form of a jointing flange. Specification 424,233 is referred to.

Title: Pressure regulator for gaseous or liquid media
IPC: G05D16/10
Filed: 1954-10-21
Abstract: 779,909. Fluid-pressure brakes. TEVES, R., and TEVES, E. A., [trading as TEVES MASCHINEN - UND ARMATURENFABRIK KOMM.-GES., A.]. Oct. 21, 1954 [Dec. 4, 1953], No. 30358/54. Class 103 (1). [Also in Group XXIX] A valve for providing an output pressure in a required relation to another pressure and suitable for use in pressure-fluid braking systems for vehicles in which a higher pressure is required for the front wheels than for the back, comprises a spring-loaded plunger 6, Fig. 1, having a seat 11 for a ball valve member 10 which has a connection 15 to a spring- loaded plunger 12, at least one of the springs having a non-linear characteristic. In operation, pressure in a conduit 2, 3 has access through the open valve 10, 11 to a chamber 16 communicating with an outlet 5. The pressure in the chamber 16 causes the plunger 12 to cornpress the spring 13 and move the closure member 10 towards its seat, thus controlling the pressure in the chamber 16. Any rise of pressure in the conduit 2, 3 moves the plunger 6 against its spring 7 to re-open the valve and raise the pressure in the chamber 16. The relation between the two pressures can be varied by varying the loading springs 7, 13, or by altering the sizes of the plungers 4, 12. The plunger 12 can be used as an indicator, for example by operating an electric switch 42, 43. The conduit 2, 3 is connected to the front brakes and the outlet 5 to the rear brakes. In a modification, the controlling medium enters the valve housing at 26, Fig. 4, and the controlled pressure passes out at 40. The pressure responsive elements, instead of consisting of spring-loaded plungers, in this case comprise members 29, 34 bonded to annular rubber members 30, 35 which are themselves bonded to sleeves fixed in the valve housing. An additional and adjustable loading spring 36 is provided for the member 34. Instead of the plungers 6, 12 or the rubber parts 30, 35, diaphragms or bellows may be employed.

Title: Cathodic sputtering apparatus
Inventor: THEUERER HENRY CHARLES
IPC: C23C14/56
Filed: 1964-08-04
Abstract: Apparatus for cathodic sputtering comprises an anode substantially surrounding a cathode, an inert gas such as hydrogen, helium, argon or neon being introduced into the evacuated space between the anode and cathode during sputtering and an electric potential being applied between the anode and cathode to effect a glow discharge so that reactive <PICT:1077214/C6-C7/1> impurities in the inert gas react with the flow of electrons from the cathode and are deposited on the anode.  The substrates which may be coated are glass, ceramics, magnesia and metals and the materials deposited may be superconductive and reactive materials such as V3Si, V3Ge, V3Ga, Ta and N6.  The anode may be the vacuum chamber (see Fig. 1 not shown) which completely surrounds the cathode or it may be in the form of a bell which surrounds the cathode on all sides except the side facing the substrate (see Fig. 2 not shown).  As shown in Fig. 3 the apparatus may comprise two cathodes 36 and 37, an anode 34 enveloping the cathodes, an inlet 33 for the inert gas and a vacuum connection 32.  The substrate 40 is supported on an electrical resistance element 41 and a movable shutter 44 is located between the cathode 36 and the substrate.  The substrate is preferably maintained 650 DEG -1000 DEG C. during sputtering a partial pressure of 10-4 torr or higher being maintained in the vacuum chamber.  After evacuating an inert gas such as argon is introduced into the chamber, the target is first sputtered in the absence of the substrate to bring the target to a steady state.  The substrate is then introduced, outgassed and then coated by sputtering. After the required film is obtained the shutter 44 is positioned between the substrate and cathode and sputtering is terminated.

Title: Spinning of viscose
IPC: D01F2/10
Filed: 1947-11-26
Abstract: Filaments, films, bands, caps, ribbons and other articles of improved physical properties are obtained from viscose by adding to the viscose and/or to the spinning bath a small proportion (i.e. 0.5-10 milli-mols. per 100 gr. of viscose and/or bath) of a quaternary ammonium compound in which none of the four organic radicles linked to nitrogen contains more than four aliphatic carbon atoms, at least three of these radicles containing only aliphatic carbon atoms and the fourth radicle, if not purely aliphatic, containing only one benzene ring; the quaternary compound may be a hydroxide or a salt, e.g. a chloride, bromide, iodide, sulphate, bisulphate or acetate. The spinning bath contains sulphuric acid and zinc sulphate, preferably with sodium sulphate and with or without a sulphate of another polyvalent metal, e.g. ferrous, manganese, nickel or chromic sulphate and, to prevent incrustation of the spinnerettes, it may also contain a long-chain quaternary ammonium compound known to be useful for this purpose.  Ripened or unripened viscose may be used, as well as viscose to which an alkali trithiocarbonate has been added. Specified quaternary compounds are tetramethylammonium chloride and iodide, tetraethylammonium hydroxide and bromide, tetra - (hydroxyethyl) - ammonium hydroxide, tetrabutylammonium chloride and iodide, phenyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide and chloride, tetrapropylammonium hydroxide, tributylpropylammonium hydroxide, tri-(hydroxyethyl)-methylammonium hydroxide, and tributylhydroxyethylammonium iodide, and examples of the use of some of these are given.  In applying the process to the production of filaments the latter are stretched during coagulation and, for this purpose, may be given a long travel of up to 250 inches through the spinning bath over a multiple-roller apparatus designed to apply a gradual tension.  Preferably, however, a part or all of the stretch is applied beyond the spinning bath either in the air or in a second bath, which may consist of water or dilute sulphuric acid or may have the same relative composition as the first bath but at a greater dilution.
