Patent GB-582506-A (GB)
Title: Improvements in, and relating to, the recovery of scrap metals
IPC: C22B7/00
Filed: 1943-12-09
Abstract: A process for the separation, recovery or refining of metals which comprises subjecting mixtures of metals or alloys at an elevated temperature, preferably above the melting point of one or more of the constituent metals, to the action of mixtures of fuel and oxygen or an oxygen-containing gas in such a proportion that the products of combustion contain no free oxygen but hydrogen and steam and/or carbon dioxide and carbon monoxide in proportions oxidising to one or more of the constituent metals and reducing to the remainder, so as to convert one or more of the metals present into an oxide or oxides, the remainder being retained as metal and separating the oxide or oxides and the metal or metals.  By this process nickel and copper may be separated from iron, preferably at a temperature between 1100 DEG C. and 1450 DEG C. and the gas mixture may be such that the products of combustion contain 7-11 per cent. of carbon dioxide, 8-1 per cent. of carbon monoxide, 10-1 per cent. of hydrogen and 15-18 per cent. of steam, the balance being substantially nitrogen. Reference is made to the separation of copper from nickel at a temperature between 1400 DEG C. and 1800 DEG C.; the separation of copper from iron at 1400 DEG C.-1500 DEG C.; the separation of lead from tin at 700 DEG C.-800 DEG C.; and the separation of iron, nickel and cobalt from aluminium at 1400 DEG C.-1500 DEG C.  The spent atmosphere from these processes may be withdrawn from the furnace and oxygen or an oxygen-containing gas added in such proportions that the mixture is again suitable for selective oxidation.  The material to be treated may be melted continuously in a vertical shaft furnace, with or without the addition of fluxes to convert the oxide formed to a fluid slag.  The metal or alloy obtained may be transferred, molten, for final purification, to a converter or similar type of furnace, in which it is again submitted to the action of a selectively-oxidising gas mixture, with or without the addition of fluxes.  Specification 9508/09, [Class 82 (i)], is referred to.

Abstract: 893,864. Relieving heads. ACCLES & POLLOCK Ltd. June 1, 1960 [June 17, 1959], No. 20740/59. Class 83 (4). A relieving head for use on a draw bench comprises three rollers 21, each rotatable about its own axis and about an axis which is parallel to the axis of the drawn tube, and adjustable about a radial axis whereby the roller axis can be inclined to the axis of the ube. The rollers are each mounted on a slide 19 and each slide has a peg which projects into a three-track spiral cam 24 which can be rotated relative to the slides by a worm 28 meshing with teeth 27 on the periphery of the cam ring. Angular adjustment of the rollers is by rotating the stem 20 after a securing nut 22 has been slackened. Screw stops 29 prevent outward movement of the rollers. The whole of the relieving head is connected to a pulley and is rotated by a motor and a speed related to the speed of drawing so that the entire surface of the tube is worked in a helical path by the rollers. The rollers have a cylindrical central portion and curved or tapered end portions, or the roller may be barrel-shaped.

Catalytic apparatus; catalytic agents, preparation of. - In apparatus for catalytic hydrogenation wherein n a nickel catalyst is used in the form of wire, turnings, &c. packed in cages, the catalytic elements are constructed so that their thickness does not materially exceed six inches. so that anodic oxidation may be. thoroughly effected. In the illustrated modification the catalyst c is packed between two gauze cylinders a, b having diameters of 18 inches and 6 inches respectively. An internal and an external cathode are employed during the anodic oxidation process. When the catalyst is in use the space within the annulus may be filled by a further gauze cylinder packed with catalyst, or it may be fitted with a perforated steam pipe f and utilized for heating the apparatus. In another form of the invention, the catalyst is packed into cylinders of a height not exceeding 6 inches, which are superimposed in the reaction chamber when in use. The gauze cylinder in which the catalyst is packed is preferably made of a metal which is more resistant to anodic oxidation than nickel, e.g. copper or a copper-nickel alloy. Specifications 203,218 and 274,952 are referred to.
