Title: Improvements in and relating to the production of ti, nb, ta, mo, v or w
Inventor: EATON RUSSELL BRAYTON
IPC: C22B5/06
Filed: 1957-07-30
Abstract: Lower halides of titanium, vanadium, niobium, molybdenum, tantalum, and tungsten are prepared by reducing the normal halides with hydrogen in the presence of a molten alkali metal or alkaline earth metal halide at at least 450 DEG C.  The sub-halides so produced are then reduced to the metal (see Group II).  The reduction may be effected by passing the normal halides in admixture with hydrogen through a column containing molten alkali metal halides or the latter may be trickled down a tower countercurrent to the halide/hydrogen mixture.  Examples refer to the production of titanium and niobium lower chlorides, using chlorides of sodium, potassium, lithium and magnesium, and mixtures thereof.  Specifications 479,014 and 632,564 are referred to.ALSO:Titanium, vanadium, niobium, molybdenum, tantalum and tungsten are prepared by reducing the normal halides thereof with hydrogen in the presence of molten alkali metal or alkaline earth metal halides at at least 450 DEG C. and thereafter reducing to metal the sub-halide formed, by reduction with an alkali or alkaline earth metal, zinc or aluminium or alloys thereof. Sub-halide production is effected at temperatures above 450 DEG C. and generally from 750 DEG  to 850 DEG C. whilst the reduction to metal may be at 700 to 1100 DEG C. According to examples (7) a solution of titanium sub-chloride in molten sodium chloride, (formed by passage of a titanium tetrachloride/hydrogen mixture counter-current to a downwardly flowing molten sodium chloride stream in a packed tower) was passed from the tower to a reaction chamber where at 950 DEG C. it was treated with a stream of sodium to form titanium sponge metal. (10) A solution of lower titanium chlorides in molten magnesium chloride was prepared by reacting titanium tetrachloride and hydrogen.  The resultant solution was heated to 800 DEG C. and 1/4 " cubes of magnesium were added with stirring.  After cooling the magnesium chloride was removed by water leaching to leave titanium sponge.  (11) Niobium pentachloride was reduced with hydrogen in the presence of a sodium chloride-potassium chloride eutectic and the resulting salt composition was mixed with a zinc magnesium alloy containing 59% of zinc, and heated in an alumina crucible in an argon atmosphere at 75 DEG C.; after cooling the product was leached with 6 N hydrochloric acid and vacuum distilled at 1300 DEG C. to produce a 99.96% purity niobium.  The molten salt composition before reduction may be filtered through a fritted silica disc.  Further examples relate to niobium production from an alkali metal halide/lower niobium halide molten mixture employing magnesium, sodium, and aluminium. Specifications 479,014 and 632,564 are referred to.

[Also in Group VIII] A layer of a mouldable cellular substance capable of conversion into resilient cellular material is formed on a supporting surface, depressed along lines constituting the outlines of a plurality of shaped articles sufficiently or insufficiently to cause separation of the articles, converted into the resilient cellular material, and separated if necessary into the articles. The supporting surface may be a travelling endless belt conveyer 12, used either with side pieces mounted on it or in conjunction with endless belts travelling at the same speed and running in vertical or steeply inclined planes at its two sides, the depressions being formed by a roller 13 provided with ridges 15. Suitable resilient materials include foam rubber and certain resilient expanded synthetic resin compositions, e.g. based on polyvinyl chloride, copolymers of vinyl chloride with vinyl acetate or vinylidene chloride, or polyurethanes. Backings or facings of textile fabrics or other flexible sheet material may be incorporated by laying the material on the supporting surface before the layer of mouldable substance is formed. In the case of textile fabrics, the necessary adhesion is provided by penetration of the foamed rubber dispersion or the like into the interstices of the fabric but otherwise an adhesive is necessary, Specification 785,256 is referred to.

Abstract: 615,059. Gas-blast switches. ETABLISSENIENTS MERLIN & GERIN. Aug. 21, 1946, No. 24923. Convention date, Feb. 24, 1944. [Class 38 (v)] In a gas-blast circuit-breaker, tubular-contacts 1, 2, one or both of which may be movable, are surrounded by a cylindrical screen 3 forming an annular passage for the pressure-gas forced through it in opposite directions, the section of the annular-passage being made at least equal to the sum of the sections of the contact-bores, to avoid loss of pressure. In Fig. 2 the entry sections of the annular-passage are independently adjustable by rings 13, 14 so as to balance the gas pressure in the event of the gas source being nearer one end of the screen than the other. The screen has directing-vanes 11, 12 to prevent turbulence, and a circular-projection 10, disposed between the contacts, imparts a preliminary deviation to the gas-blast towards the axis of the contacts thereby preventing eddies. In a seriesbreak arrangement, Fig. 4, part of the compressed-gas admitted to an annular-chamber 16 formed by an insulator 15 housing one break, is conducted via a conduit 19 to another chamber formed by an insulator 15<1> housing the other break, the adjacent ends of the insulators 15, 15<1> being closed by a hood 17 having common exhaust-orifices 18 for the arcgases from the contacts 2, 2<1>. In Fig. 5, compressed-gas supplied over a single conduit 21 is uniformly distributed by directing-vanes disposed at the ends of the screens 3, 3<1> in tapering circular casings 22, Fig. 6 (not shown). Alternatively, the conduit 21 may be connected to the screens by inlets set at 180 degrees to each other, or the conduit 21 may itself be duplicated. The screens may be insulating or metallic, in which latter case they may be connected to the contacts by resistances, inductances, or capacitors. They may alternatively be made from resistance material and so shaped that the resistance is graded lengthwise of the screen.

[Class 39 (i)] [Also in Group XXXV] In electric discharge lamps wherein at least one electrode is heated at starting this heating current flows through a winding which is subjected when the discharge strikes to an opposing effect set up by the main discharge current so that during normal running heating of the electrode is reduced. The electrodes 2, 3 or heater coils therefor are connected to the secondaries 4, 5, Fig. 1, of a transformer auxiliary windings 10, 11 being in these heater circuits ; the main discharge flows through chokes 8, 9 the current in which opposes that in the coils 10, 11. In a modification of this arrangement the coils 8, 10 and 9, 11 are combined into two coils suitably connected to the supply and heater transformer 4, 5, 6 to give the reduction effect. In another form the reduction is obtained by using a closed iron core 14, Fig. 3, for the heater transformer and the coils 8, 9 on a core 15 with an air gap between it and the core 14 ; the flux produced in the core 15 opposes that produced by the transformer primary in the core 14. The main discharge may be varied by a tapping on the primary 6. This reducing effect may be combined with a lamp using auxiliary starting electrodes 19, 20, Fig. 4, supplied from secondaries 21, 22 ; the opposing coils of the arrangement shown in Fig. 1 are now combined into one winding 13. If several discharge lamps are used together some of the windings may be common to all the lamps.
