Title: Improvements in or relating to leaching processes for the extraction of metals from their ores and the like
IPC: C22B3/14
Filed: 1924-08-22
Abstract: In the extraction of copper, zinc, or like metals from ores by ammonia solution containing some carbon dioxide, the material, after the leaching liquor is drawn off, is treated with a previously made mixture of steam and ammonia with or without carbon dioxide.  The vapours condense on the ore and wash out the remaining solvent without causing any precipitation of metal oxide upon the ore. Preferably the liquor thus formed by condensation is collected and used as leaching liquor for the next batch of ore.  The process is advantageously applied to ore which has been treated by the process of Specification 185,242 or 190,246, in which case the ore may contain chrvsocolla and other oxidized copper compounds insoluble in ammoniacal solutions; the ore is first dehydrated at 400 DEG  C. and then heated to 340 DEG  C. in a reducing gas, while if it contains copper sulphide it may be roasted at 400-500 DEG  C. in an oxydizing atmosphere and then heated in a reducing gas at 300-355 DEG  C.  In an example the ore is heated in gas from a producer the ammonia from the producer gas being washed out and used to replace that lost during the process of leaching.  The mixed vapours required for the final treatment of the ore are obtained by evaporating the ammonia solution obtained from the producer gas and adding carbon dioxide from the combustion of the producer gas before its final discharge from the apparatus.  This combustion may supply the heat required in the various operations of the process.  In another example the vapours arising from the still in which the extraction liquor is distilled for the precipitation of the copper are employed for the final treatment of the ore.  Specifications 220,720 and 228,260 are also referred to.

Title: Metallo organic polymers, their preparation and utility
Inventor: MANUEL THOMAS ASBURY
IPC: C08C19/26
Filed: 1963-05-22
Abstract: Metallo organic polymers obtained by reacting a Group VIII metal carbonyl compound with a natural or synthetic rubber are useful as additives in minor amounts in gasoline, jet fuels, heating oils, hydrocarbon and synthetic lubricating oils, diesel fuels, and greases.ALSO:Metal carbonyl-polymer complexes are prepared by heating in bulk or in solution, e.g. at 30 DEG  to 150 DEG  C., a polymer or copolymer of a conjugated aliphatic or cyclic diene hydrocarbon with a Group VIII metal carbonyl compound in the absence of air or oxidizing compounds or gases.  When the process is carried out in solution, the solvent may be a hydrocarbon, ether, ketone or CS2.  A polar solvent (other than an acid, acid anhydride or acid chloride) may be present to protect the polymer from thermal degradation.  In an embodiment, heating may be wholly or partially replaced by the use of high energy or actinic radiation, e.g. gamma or U.V. irradiation. Suitable diene polymers include butyl rubbers (diene-isoolefin copolymers), copolymers of dienes and vinyl aromatic hydrocarbons, homopolymers of dienes such as butadiene, isoprene, cyclopentadiene, copolymers of C4 to C8 dienes and C2 to C6 olefins, and natural rubber (including latexes thereof).  These polymers may optionally include minor amounts of copolymerized units of other monomers, e.g. styrene, divinyl benzene, acrylonitrile, ethacrylonitrile, vinyl acetate, esters of acrylic and C1 to C3 alkyl-substituted-acrylic acids, vinylidene chloride, vinyl chloride and chloroprene.  The metal carbonyl used is preferably an iron, cobalt or nickel carbonyl. It may be in monomeric or polymeric form and may contain other groups in addition to the carbonyl group(s).  The metal carbonyl-polymer complexes can be vulcanized with the usual curing agents and accelerators (many specified), optionally in the presence of other natural and synthetic elastomers.  The polymer complexes may also be compounded with elastomers, fillers such as clays, hydrated silica, silica, talc, diatomaceous earths, kaolin, lithopone, lead dioxide, zinc oxide, magnesium oxide, titanium dioxide and carbon black, fatty acids, e.g. stearic acid, waxes, tars, synthetic resins, plasticizers, oils, animal and vegetable fibres, synthetic fibres, asbestos, glass fibres, pigments and antioxidants, e.g. phenyl-b -naphthylamine. Such vulcanized and compounded products are suitable for use as rubbery articles, e.g. belting, hose, bags, and tyres. The polymer complexes can be heated to obtain polymers having magnetic characteristics; if heating is carried out in the presence of air or oxidizing gases or compounds (e.g. a reducible Cu compound) the metal carbonyl moiety i-S converted to metal oxide while, in a non oxidizing atmosphere, the metal carbonyl i converted to elemental metal.

Abstract: 1,066,642. Wick burners. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. May 20, 1964 [May 25, 1963 (2)], No. 20835/64. Heading F4T. An oil burner comprises a plurality of main wicks 37 movable vertically in guide tubes 29 by means of a rack 27 and a pinion 23, an auxiliary wick 42 movable vertically from a retracted position in an extinguisher tube 40 and adapted to be ignited by an electric heater 54 and to ignite the main wicks 37 and linkage connecting the main wicks, the auxiliary wick and contacts 55 for the electric heater 54 so that when the pinion 23 is rotated to raise the main wicks the auxiliary wick is also raised and the heater 54 is energized. The rack 23 and supporting tubes 38 for the main wicks are secured to a disc 28, and a supporting tube 41 for the auxiliary wick 42 passes through a cutout 48 in the disc 28, but when the disc 28 is raised by the rack the cut-out engages a nut 45 threaded on to the supporting tube 41 and therefore raises the auxiliary wick. The nut 45 has a tongue 44 which extends into a vertical slot in a guide plate 47 and the position of the tip of the auxiliary wick, when raised, can be adjusted by rotating the supporting tube 41 to move the nut. A spring acts between the nut and a cover 12 of an auxiliary fuel reservoir 11 to return the auxiliary wick downwardly. The tips of the main wicks extend into an annular fire tray 32 which contains a glass fibre ignition wick 39 contacting all the main wicks and which has an aperture 50 immediately above the auxiliary wick 42 covered, during burning, by the upper side plate of a U-shaped member 49 freely swingable on one of the wick guide tubes 29 located adjacent the auxiliary wick 42. The cover 49 is connected by a rod 52 to a link plate 19 loosely mounted on the shaft 15 of the pinion 23 but adapted to be rotated by a pin 16 on the shaft engaging an abutment 18 on the link plate. When therefore the shaft is rotated to raise the main wicks and the auxiliary wick, the cover 49 is swung to uncover the aperture 50 and the end of the rod 52 connected to the cover urges the contacts 55 together to energize the electric heater. When the shaft is released, a spring 20 acting on the link plate returns the shaft, and to prevent the main wicks from being forced downwardly too far a brake is associated with the shaft and comprises a U-shaped brake 24 loosely mounted on the shaft and having a lug 25 adapted to engage the rack 27 and an abutment 26 adapted to engage the linkplate 19. The brake 24 is normally tilted by gravity so that the lug 25 is out of engagement with the rack 27 but when the link plate is returned by its spring the brake is caused to rotate and the lug 25 engages and stops the rack. The main wicks are extinguished by rotating the shaft in the opposite direction to draw the wicks into the guide tubes. Two auxiliary burners and two electric heaters therefor may be provided and operated simultaneously by the pinion shaft. The burner is provided with a chimney and is mounted in front of a reflector and is covered by a guard hinged to the reflector.

Title: Improvements in or relating to the preparation of composite pigments containing titanium
IPC: H02K1/08
Filed: 1934-07-17
Abstract: A composite pigment consisting essentially of calcium sulphate and titanium dioxide precipitated one on the other or both simultaneously, the precipitate being then washed and heated, is prepared by employing the starting materials or allowing the titanium dioxide and calcium sulphate to form in such relative quantities that the precipitate after washing contains 40--60 per cent of titanium compound reckoned as titanium dioxide.  The precipitation may be effected at atmospheric or higher pressure. During or after the washing step chlorides, fluorides, phosphates or other phosphorus compounds, or the acids corresponding thereto, and organic compounds may be added as sintering agents and to improve the colour of the pigment.  Fusing agents such as alkaline compounds may be added before the precipitate is calcined and neutralizing agents may be added before or after calcination. Preferably calcination is carried out so that the titanium dioxide is obtained in the form of rutile crystals, e.g. by heating to 800--1000 DEG  F.  In an example, a paste of calcium sulphate is added to a solution of the double sulphate of titanium and iron and the mixture is heated until practically all the titanium is precipitated; alternatively the calcium sulphate may be formed in the titanium sulphate solution prior to or simultaneously with the precipitation of the titanium compound by adding carbonate, chloride, hydrate or other compound of calcium to the solution before or during the precipitation.  British Specifications 281,459, [Class 95], 364,112 and 387,720 and U.S.A. Specification 1,902,204 are referred to.
