Abstract: 1469050 Discharge tubes GOULD Inc 8 April 1975 [26 June 1974] 14420/75 Heading H1D [Also in Divisions H2 and A5] A discharge tube used as a switching device between a supply and a load, comprises an elongated glass envelope 10 filled with Xenon gas at a pressure slightly less than atmospheric and a pair of electrodes 12, 13. The tube is provided with an element 16 comprising a pair of spaced loops 16a, 16b, the loops being of greater diameter than that of the tube and are placed one adjacent the electrode 12 and one midway between the two electrodes.

Title: Improvements in or relating to soap compositions
Inventor: COCKS LESLIE VICTOR
IPC: C11D9/12
Filed: 1949-05-30
Abstract: A soap powder made from a mixture comprising molten soap and sodium carbonate is mixed with not more than 15 per cent by weight of finely-divided calcium carbonate.  The calcium carbonate may be mixed with a diluent to improve its uniformity of dispersion before being mixed with the soap powder.  The preferred diluent is sodium carbonate.  Naturally occurring minerals such as limestone or calcite or minerals containing calcium carbonate may be used. The activity of the calcium carbonate may be enhanced by grinding or other mechanical treatment and, if desired, the calcium carbonate and diluent may be mixed and ground together. Preferably 1-10 parts of sodium carbonate are mixed with 1 part of calcium carbonate and ground, the ground mixture being added to the soap powder so that the final composition contains up to 2 parts calcium carbonate for 100 parts soap powder. The ground calcium carbonate/diluent may be sieved on to the soap powder. The soap content may be between 20 and 80 per cent of the powder, preferably from 15 to 40 per cent, while the sodium carbonate content may be between 10 and 50 per cent Other substances such as silicates and per-compounds may be present in the powder, but compounds which will hinder the precipitation of the hardness of the water by the sodium carbonate, such as sodium pyrophosphate, should not be included.  In an example a soap is made from a fat charge consisting of 85 per cent palm oil and 15 per cent palm kernel oil, and 69.5 per cent of the soap base containing 70 per cent anhydrous soap is mixed with 16.8 per cent anhydrous sodium carbonate, 12.1 per cent 80 DEG Tw. sodium silicate (neutral) and 1.6 per cent water. The mixture is sprayed to form a powder, screened to remove that portion passing a 60 mesh/inch sieve, and 100 parts of the screened powder then mixed with 10 parts of precipitated chalk.  Other examples are given.  Specification 607,274, [Group I], is referred to.  The Provisional Specification refers also the use of ground felspar, fluorspar, magnesium fluoride and aluminium silicate in place of calcium carbonate.

Title: Process of casting titanium and related metal and alloys and apparatus therefor
Inventor: OPERHALL THEODORE
IPC: B22C9/04
Filed: 1957-05-07
Abstract: 842,158. Casting-processes. MISCO PRECISION CASTING CO. May 7, 1957, No. 14574/57. Class 83 (1). [Also in Group XI] When casting metals of Periodic Group IVA or alloys thereof, the mould cavity is lined with a thin film of a metal of Group IVA or an alloy thereof, which barrier film protects the molten metal from reaction with the mould material. The film, preferably between 0.0003 and 0.000001 inch thick, may be vacuum-deposited on a pattern for transference to a shell mould, or on a destructible pattern for lining an investment mould. It may have an outer layer or layers of a metal of good heat-conductivity, such as Cu, Cr, Ni, Fe, Co, applied by electrodeposition &c., to a thickness of 0.001-0.005 inch, the layer or layers serving by chilling to prevent breakdown of the barrier film by the melt. The layer or layers may be removed from the cast article, or retained as a protective layer. An investment mould 11a having a titanium barrier film 13 and an outer layer, 14, has shot 15 at the bottom for additional chilling effect. The mould is mounted within an inductive heating coil 37, Fig. 5, in a chamber 30, which is filled with inert gas. Above the mould is mounted a crucible 34 within a heating coil 36, which melts the upstanding portion 34d, the molten pool created thereby melting the plug section 34a and flowing into the mould. A pressure differential above and below the crucible may assist the flow. In a modification, Fig. 7, titanium is melted by induction heating in an evacuable chamber 21, which is tilted to pour the melt into the inductively-heated mould 11 supported by clamps 34, 35, in an extension to the chamber. When casting alloys of a metal of said group, the barrier film need not be of the same alloy, but may be of the pure metal of the group, or a different alloy of said metal.

Title: Process for the production of facing bodies attached to a support
IPC: B23K13/00
Filed: 1944-07-31
Abstract: 586,233. Moulding metal powder. PHILIPS LAMPS. Ltd., WILDE. H. DE, and PINKNEY. A. J. July 31, 1944, No. 14602. [Class 87 (ii)] [Also in Groups II and XXII] In a process for producing a facing body on a metal support comprising the steps of moulding and heating particles of the facing material with a matrix of iron particles to a temperature sufficient to produce a coherent body and utilising the heat available during this operation for welding the resulting body to a metal support, the heating is effected by high frequency induction in a crucible of refractory conducting material which forms a part of the mould. The invention is described with reference to the facing of burner nozzles, pulper blades, rock drill bits and valves of internal combustion engines with a mixture of tungsten carbide and iron. In the first example, Fig. 1, pulper blade 1 is inserted in a graphite mould 2 built up from two halves each of approximately semi-cylindrical form. The powdered mixture of tungsten carbide and iron is inserted into the cavities 4 and heated by a high frequency coil 6 to form coherent masses welded to the blade. Fig. 6 shows a mould suitable for producing an oil burner with tungsten carbide nozzles and a stainless steel base. The member 9 of stainless steel has a central bore and at each side is recessed to receive a graphite core comprising a cylindrical body 15 drilled to receive rods 17, Fig. 9. Each core is drilled and tapped at the base so that the two cores may be secured together by a screwed graphite rod 11 passing through the bore of the member 9. A mould 12 is inserted over each end of the member 9. After filling the cavities with the tungsten carbide and iron mixture and sintering, the stainless steel body 9 is cut in half and the mould and cores removed to leave two separate burner units. In a modified form, a single core is anchored by a graphite bolt to one side of a stainless steel base and extending concentrically through the upper portion of the mould is a graphite tube through which a graphite plunger may be passed to press down the mixture. The facing or inset may be built up layer by layer. A form of mould for forming tungsten carbide facings on the surfaces 25 of a rock drill 23, Fig. 12, is built up from four sections such as that shown in Fig. 16, adjacent inclined faces 28 forming depressions which are filled with the powdered mixture before the insertion of the inverted base member 23. In a further application of the invention, the stem 30 and cap 31 of a hollow internal combustion engine valve, Fig. 17, are joined together by a sintered powdered mass 33 which also forms a hard facing. Specifications 349,732; 398,717 and 530,639, [both in Group XXII], are referred to.

[Also in Divisions Cl and C5] A process for separating the phases of an emulsion comprises the steps of introducing into the emulsion a gas or vapour in the form of bubbles so that the bubbles rise through the emulsion at least substantially in a turbulent flow, adjusting the rate of flow of the gas or vapour in a plurality of vertically extending and horizontally distinct zones of the emulsion in such a manner that the said rate of flow varies in substantially discrete steps from one zone of the emulsion to an adjacent zone, until the disperse phase of the emulsion together with any solids present is at least substantially separated from the continuous phase of the emulsion. The gas may be introduced under pressure from outside or may be generated within the emulsion by heating, lowering of pressure, or chemical or electrochemical action. The process is particularly applicable to separating emulsions of mineral oil in water such as oilfield waste water.
