Filed: 1968-06-14
Abstract: 1278044 Treatment of clays J F DUNCAN and K J D MACKENZIE 13 June 1969 [14 June 1968] 28377/68 Heading C1A Clay is hardened by heating at 850 C. or higher and simultaneously maintaining an electric potential across the clay. Either direct or alternating current may be employed with voltages from 5-2500 volts and currents from a few microamps to 10 milliamps. Preferably baking temperatures of 850-1500 C. and subatmospheric pressures are used. Under some conditions, especially those involving use of alternating currents, a surface can be produced having a shiny black appearance which can be made white again by further heating in air at temperatures of between about 900 and 1100 C. In an example pellets of kaolinite are placed between platinum electrodes and at a temperature of 1050 C. subjected to a direct current of 1 milliamp. at a potential of 2500 volts for 15-16 hours under a pressure of 10<SP>-5</SP> mm. of mercury, to obtain clay of enhanced hardness. Halloysite may also be used as the starting material and the end product may consist largely of mullite.

Abstract: 338,654. Mackenzie, R. W. R., Robinson, E. H., Lumsden, D., and Fort, M. Sept. 23, 1929. Fireproofing; proofing processes and materials. -Cotton, linen, or other fabrics composed of cellulose are loaded and filled in an invisible way with mineral loading agents by subjecting them to a plasticizing treatment whereby they are rendered sticky as regards the filling or loading material, and thereafter subjecting the fabric to a setting bath to dispel the plastic condition. As plasticizing-agents, there may be employed sulphuric acid, caustic alkali, carbon disulphide, cuprammonium solution, or copper sulphate and ammonia in presence of caustic alkali. The loading or filling may be china clay, talc or barytes, alone or together with unwoven cotton, wood fibre, paper, paper &c. pulp. The filling may be applied to the fabric before, during, or after the plasticizing treatment, and pressure may be applied by rollers &c. before the setting bath, while tentering may be employed at any stage of the process. In some cases, the fabric is treated with loading material in caustic soda, sprayed with copper sulphate which may also contain loading, plasticized by treatment with ammonia or ammonia vapour, and soured. Examples are given of the process applied to previously-loaded fabrics and to non-loaded fabrics. Fabrics treated by the process have increased strength and lustre, are rendered fire proof, and are given a linen-like handle, smoothness and freedom from hair, closeness of texture, resistance of the loading to dusting out in beetling and other finishing processes, ability to withstand washing, and increased weight and thickness.
