Title: Improved manufacture of wooden sheets
IPC: D06N7/00
Filed: 1931-05-04
Abstract: 378,385. Treating wood; compound sheet materials. HERZOG, R. O., 18, Kaiser- Wilhelmstrasse, Steglitz, and BURGENI, A., 54, Unter den Eichen, Lichterfelde- Went, both in Berlin. May 4, 1931, No. 13155. [Class 140.] Wood sheets of leather-like softness and pliability are obtained by chemically loosening and swelling the wood structure until it becomes pliable and impregnating it with substances for maintaining the swollen and pliable condition. The pliability may be produced by any process for the production of cellulose, alkaline, acid or oxidizing, provided it is not carried too far, viz. to the production of hydrocellulose. Lime wood veneers are, for example, treated for six hours with a cold 4 per cent caustic soda solution, or for three hours at 75‹ C. with 0.1 per cent solution, and maple, oak, pine, and other woods with a cold 6-16 per cent solution for two hours. The wood may be bleached, for example, with sodium hypochlorite or 2 per cent oxalic or sulphuric acid and then is treated with water-soluble substances of low vapour pressure such as glycerine, monoacetin, and lactates to make the pliability permanent. Liquid, dissolved or emulsified hydrocarbons, fats, oils, soaps, and emulsifying agents such as sulpho- and oxy-fatty acids and their derivatives, turkey-red oil, monopole soap, &c. may simultaneously be added to enhance the pliability. Soluble organic compounds such as cane, invert or starch sugar, urea, or soluble salts such as sodium chloride or ammonium sulphate or other easily soluble substances may also be added as fillers to prevent shrinkage. To strengthen the material, elastic film forming colloids such as rubber, polyvinyl acetate, polyacrylic acid, glue, gelatine, and cellulose esters may be added. The wood may be soaked with vinyl acetate, acrylic acid, and other condensable or polymerizable substances, to which plastifiers may be added, which are then condensed or polymerized to give the colloids. The colloids can also be applied by brushing, dipping, or spraying as a surface (oating only. The wood may be given, before, luring, or after the process, a mechanical working in calenders or presses to increase the pliability, and may be rolled to give a uniform product. The thin wood sheets may be combined with a support of felted fibres, fabrics, metal cloth or foil by means of an adhesive which may be the same as the protective coating, e.g. polyvinyl acetate and cellulose esters. The threads of the warp and weft of the fabric may be of different strengths to emphasize the structure of the wood. The compound sheets can be used for roll curtains, as furniture, upholstering, wall paper, carpets, &c., and can be cut into strips for making basketwork. Specifications 21190/95, [Class 145, Wood &c.], and 25273/09, [Class 140, Waterproof &c. fabrics], are referred to.

Title: Improvements in or relating to the electro-chemical treatment of copper ores
IPC: C22B3/08
Filed: 1924-05-29
Abstract: 238,962. Mackay, H. S. May 29, 1924. Roasting; solids, treating with liquids. - An electrochemical process for extracting copper from sulphide ores and concentrates comprises roasting the ore, leaching to obtain copper sulphate solution, purifying the solution, and electrolyzing, the roasting and purifying being so regulated as to obtain a liquor of uniform composition. The roasting may be effected in the furnace described in Specification 205,528 or in a standard 7-hearth roasting furnace, preferably modified as shown in Fig. 2. Heat from any source or hot air from the air cooling system of the furnace is added to the lowest hearth by a pipe b and a by-pass pipe a is arranged so as to take off some of the gases from the lower hearths direct to the chimney without passing through the upper hearths, so as to secure a sufficiently high temperature in the lower hearths without overheating the upper hearths. The roasted material is leached in tanks F, preferably with two solutions of different acid content, the first leaching being with a liquor of low acid content and high specific gravity so as to obtain a substantially neutral solution in a tank G, and the second with liquor of higher acid content and lower specific gravity which after use is collected in a tank H. The liquor in the tank H receives acid from a tank N and is then used as the first liquor for a fresh batch of ore. The liquor from the tank G is led to a store tank T and thence to an agitator I in which it is treated with an oxidant such as air and a purifying agent which may be calcium carbonate when it is desired to remove some sulphate radical as well as iron and aluminium, or copper oxide or carbonate ore or copper hydrate when it is desired to remove iron and aluminium without removing any sulphate radical. The liquor from the agitator I is led to a filter K, the filtrate passing to a tank L and thence to a tank P where it receives an addition of acid if desired from the liquor coming from the electrolysers M so as to standardize it before it passes to the electrolytic cells. The rest of the liquor from the electrolyzers M is led to the tank N for use in leaching the ore. The residues in the leaching tanks F are freed from leaching liquor in the following manner :-When the leaching liquor has flowed through so as to expose the top of the ore, the bottom outlets are closed and water is added in quntity equal to that of the solution contained in the ore mass. The outlets are then opened, and the water displaces the solution downwards. Specifications 26138/13 and 194,353 are also referred to.
