Title: Improvements in condensing zinc vapor
IPC: C22B19/18
Filed: 1948-12-29
Abstract: 648,529. Condensing zinc vapour. NEW JERSEY ZINC CO. Dec. 29, 1948, No. 33416. Convention date, March 11. [Class 82(i)] 82(i)] A method of condensing zinc vapour comprises throwing molten zinc outwardly from a plurality of vertically spaced points disposed in a closed condensing chamber, and passing a gaseous stream containing zinc vapour in contact with the said molten zinc. The molten zinc may be obtained by raising it vertically from a body of molten zinc in the chamber e.g. by a screw lift and thrown outwardly by centrifugal force. Fig. 1 shows a condensing chamber 10 having a zinc vapour inlet 11 and a waste gas outlet 12. Baffles 13 and. 14 prevent splashing of molten zinc into the inlet and outlet respectively. The chamber contains a body of molten zinc up to a level a determined by an overflow 17. A screw lift 21 is in the form of a body member 25 having a spirally disposed open-topped channel 22. The body member passes through a gland 44 in the roof of the chamber and its drive shaft 26, supported on bearings 45, is keyed to pulley wheel 47. Rotation of the screw lift in a clockwise direction causes molten zinc to flow up the open-topped channel and to be flung outwardly over the retaining wall 23. Other forms of screw lift may be employed. Thus the retaining wall, provided with one or more openings, may be a stationary cylinder. The spiral channel may be in the form of a groove cut in the surface of the body member. The body member may dip into a well in the base of the chamber and, further, it may be mounted in a bearing at its lower end. Specifications 601,247 and 620,644 are referred to.

Title: Improvements in the manufacture and production of products similar to wax or petroleum jelly
IPC: C10G73/00
Filed: 1937-12-09
Abstract: 506,678. Hydrocarbons; alcohols; ketones. JOHNSON, G. W. (I. G. Farbenindustrie.Akt.-Ges.) Dec. 9, 1937, No. 34106. [Class 2 (iii)] Products resembling wax or petroleum jelly arc obtained by heating distillation residues of high molecular weight fatty acids with decarboxylating catalysts, and reducing the products with hydrogen. Residues obtained by distillation of fatty acids. from the saponification of natural oils, fats or waxes, e.g. coconut, pahn kernel, castor, linseed, soya bean, and train oils, beef tallow, carnauba and montan waxes or from the oxidation of paraffins or hydrogenation products of coals, tars, and carbon oxides may be treated, in particular those obtained by distillation under reduced pressure, if desired while leading in, for example, steam, water, benzine or benzene, as described in Specification 213,267, [Class 32]. The residues may first be purified as by hydrogenation. Waxy, oily or fatty substances may be added before or during the working up. Metallic iron or nickel or manganese oxide or even the walls of metallic reaction vessels may be used as catalysts for the decarboxylation, generally at above 200‹ C. Increased pressure may be used. The treatment is generally continued until evolution of carbon dioxide ceases, the product then consisting of ketones. The subsequent reduction may be effected with hydrogen at, 10-250 atmos. and 100-500‹ C., in thepresence of catalysts such as metallic nickel, cobalt or iron or tungsten sulphide, preferably on carriers, or with zinc and acid or sodium and alcohol. It may be interrupted when part of the ketones is still present as such or as alcohols. The products are mainly hydrocarbons and/or alcohols of high molecular weight. They may be used in oil pastes, for protecting metals and other substances from injurious gases or, when fully hydrogenated, as bases for salves. In examples: (1) and (2) the residue from the distillation according to Specification 213,267 of fatty acids obtained from soya bean oil is hydrogenated, decarboxylated by heating with iron powder, and then hydrogenated to products resembling ozokerite or petroleum jelly ; (3) fatty acids made by oxidation of paraffin wax synthesized from carbon monoxide and hydrogen are distilled with steam under reduced pressure, and the residue similarly treated ; (4), (5), (6) the residue after distilling crude fatty acids obtained by oxidation of brown coal paraffin wax is heated with iron powder to give a ketone mixture. This is hydrogenated alone or after mixing with refrigerator oil, or, is dissolved in butyl alcohol and reduced by adding sodium ; (7) the distillation residue of the oxidation product of synthetic paraffin wax is heated with iron, and reduced with hydrogen. Further hydrogenation with fresh catalyst removes the colour.

Abstract: 521,824. Mould materials. DEUTSCHE EISENWERKE AKT.-GES. Nov. 29, 1938, No. 3,4724. Convention date, Jan. 10. Addition to 441,335. [Class 83 (i)] A lining for centrifugal moulds comprises, in addition to the small bars or flakes, as in the parent Specification, metallic or non-metallic grains. When casting steel or other metals having a high melting point the grains consist of refractories such as quartzite, magnesite, aluminium nitride, or calcined alumina and should be between 0.5 and 2 mm. in size. Smaller grains are used when casting brass. If the grains are disposed near the mould wall a slower speed of rotation is sufficient than is necessary when a mixture is used and if they form the inner face a higher speed. Permeability to gas is increased by uniformity of grain size and thermal insulation by increase in size. Binders may be used if they do not fill the interstices and practically cease to bind after the casting operation, e.g., silica gel, alkyde resin in acetone, or sulphuric acid and sulphite lye with sand or ceramic grains. The lined mould may be heated from the inside to remove volatile constituents and reduce the loss of heat when casting steel &c. In another modification mixed or granular material free from binder may be applied to a mould lined with mixed material including a binder, this layer remaining in the mould when the casting is drawn.
