Abstract: 911,901. Coating with metals; granulating. MORLE, C. W., and HODDING, H. S. June 19, 1959, No. 21102/59. Class 82 (2). A conductive porous strip is formed by suction depositing fibres, the exterior at least of which are metallic, on to a substrate and then bonding the fibres by fusion or by spraying metal particles on to the deposited fibres. The fibres may be aluminium or glass, quartz, asbestos or synthetic resins such as tetrafluorethylene coated with aluminium by spraying or vacuum or inert gas deposition. The substrate may be of glass, asbestos or cellulosic fibres or metal gauze. A suspension of the fibres in water or water containing a resin and starch is agitated by propellers 4 in a tank 1. A drum 7 with a porous ceramic surface is rotated in the suspension and suction is applied to the space enclosed by the shield 9 so that a deposit of fibres is formed on the rotating drum surface. The deposit is dried by infra-red lamps 17 and fused by a high-frequency coil 12 to form a selfsupporting continuous strip. Metal particles may be sprayed on to the fibres from spray gun 16 in addition to or instead of the fusion treatment. In a modification the fibres are deposited on a porous textile or metallic fabric bonded around the surface of the rotating drum. The coated strip may then be passed through a second treatment tank where a further fibrous deposit is formed followed by a further fusion and/or spraying operation. The fibrous suspension may also include a mixture of metal and non-metal fibres such as rayon or cotton and the deposited fibrous strip may be annealed at 300‹ F-400‹ F. and also cold rolled. A dielectric film may be formed over the coated strip by electrolysis in a solution of borax and boric acid. The metal fibres may be made by centrifuging superheated molten aluminium through orifices up to 0.005 inches. The aluminium should be maintained at 1450‹ F. and the surface speed of the centrifuge should be 4000 to 5000 feet per minute.
