Abstract: 1,205,852. Carbon fibre reinforced resins. BP CHEMICALS (U.K.) Ltd. 11 June, 1969 [26 June, 1968], No. 30615/68. Heading B5A. [Also in Division C7] Carbon fibres, e.g. in the form of hanks or twists of multi-filament strands, woven mats or fabrics, which may contain fibres other than of carbon (e.g. glass), are coated with one or more ionizable resins by electrodeposition to produce carbon fibre reinforced plastics articles. The ionizable resin is preferably a phenolic or thermosetting acrylic resin, but may be any addition copolymer or polycondensation product, e.g. unsaturated maleinized drying oil, epoxide or alkyd resin, or phenol or melamine formaldehyde resin, and contain -COOH, -SO 4 H, -SO 3 H and -OPO(OH) 2  anionic, or -N(R 3 )<SP>+</SP>Cl<SP>-</SP>, -NH 3 <SP>+</SP>Cl<SP>-</SP> or quaternary ammonium cationic groups. The coated fibres may be formed into the reinforced article in the absence of further plastics material, or may be dispersed in a different thermoplastic or thermosetting resin, e.g. comprising unsaturated polyester such as formed by interesterification of a (e.g. neopentyl) glycol, phthalic or trimellitic and maleic anhydride. Coating is preferably carried out in an aqueous medium containing a resin having carboxyl groups neutralized with ammonia and feeding the fibre over phosphor bronze strips. Two or more coats may be applied by successive immersions. The coated fibre may be hot pressed to give a cured laminate. For example, dried tows of coated fibres may be soaked in an epoxy resin solution, then transferred to a " leaky " mould which, with the plunger top pressed down and surplus resin allowed to drain away, is oven heated and cured at 125‹ C.

Filed: 1928-10-24
Abstract: 299,463. Anode Rubber Co., Ltd., (Assignees of Darby, C.L.). Oct. 28, 1927, [Convention date]. Cable joints are insulated by the electrophoretic deposition thereon of rubber from an aqueous dispersion such as natural rubber latex. The brazed, butt-welded, or spliced joint 22 is carried on a frame 18 fitted with' sheaves 19, 20 so that it can be immersed in the bath 11 in which the rubber dispersion is maintained in circulation by a pump 13. The joint 22 is surrounded by a foraminous cathode 25 lined with a ceramic diaphragm 24 and having the lower part hinged to allow the introduction of a continuous cable. The cable 21 forms the anode being connected at one end to a lead 30. The electrophoretic deposition is continued until the layer of rubber equals or exceeds in thickness the cable insulation, the cut surface of which has been prepared with a coating of rubber cement. The conductor may be coated with a layer of zinc to improve the adhesion of the deposited rubber. The deposit is subsequently dried by immersion in an electrolytic bath to remove the bulk of the moisture by electroendosmose. The remaining moisture is evaporated by heating currents induced in the cable. A vulcanizing agent and an accelerator therefore may be mixed with the liquid bath, the deposited rubber being vulcanized thereby with or without heating.

Abstract: 628,183. Heat-treating metal powders. WELLMAN CO., S. K. Oct. 18, 1946, No. 31039. Convention date, May 3. [Class 72] [Also in Group XIII] Metallic powder is dried and annealed after washing with dilute sulphuric acid to remove films of oxidation followed by water to remove the resulting acid solution, in a heat insulated autoclave 15. The air therein is exhausted through a pipe 23 and is replaced by superheated steam introduced through a pipe 21. The steam is forced downwardly through the powder which is supported on a filter cloth 16, and is discharged through a pipe 17. The steam drying and annealing treatment is 'followed by admitting through a pipe 22 a non-oxidizing gas to displace the superheated steam. The autoclave heat insulation 24 is then removed and water sprays cool the autoclave and its contents to room temperature.

Abstract: 1,271,592. Rolling patterns. LENINGRADSKY INSTITUT TOCHNOI MEKHANIKI I OPTIKI. 30 June, 1970, No. 31495/70. Heading B3M. A relief pattern is formed in the surface of a workpieee by means of a spherical deforming tool, the tool being pressed into the surface while being given a composite feeding movement relative to the surface. In. one embodiment, Fig. 8, a pattern is formed in the surface of a cylindrical body 2 while the body is rotated about an axis A-A. The tool is carried by an arm 5 which is urged by a spring 23 towards the surface. The arm is held in a sleeve 7 and is fed both axially of the body in direction 5 and is reciprocatedin the same direction. The speed of rotation of the body and the amplitude of the tool. feeding movements are arranged so that a desired pattern is produced. The reciprocating movement is generated by a motor-driven eccentric 11 coupled to the sleeve 7. Similar arrangements are used for forming a pattern on either the end face of a cylinder or the internal surface of a hollow cylinder. In the case of the end face, the tool is simultaneously indexed and reciprocated along a radius of the cylinder. For patterning a workpiece which is not a body of revolution, Fig. 4, the tool rotates about a fixed axis P P<SP>1</SP> and simultaneously reciprocates normal to the rotary movement, while the workpiece is fed in direction S. The tool may be formed from a hardened steel ball or from a spherical diamond.
