Abstract: 1,130,820. Electro-phoretic coating of fine conductive filaments. HORIZONS Inc. April 20, 1967 [May 4, 1966], No.18297/67. Heading C7B. Conductive fine filaments i.e. of diameter 0.4 to 2 mils n10 to 50Á are electro-phoretically coated with short (0.5 to 10 mms) fine (0À1 to 5 Á diameter) single crystal fibres ("whiskers") from a suspension in a liquid, the whiskers deposited being aligned with the filament. The suspension may also include a resin binder and optionally a metal powder e.g. Ag, or the whisker coating may be subsequently impregnated with a resin or metal. The binder may be subsequently burnt out and the product sintered to densify the coating. Non-conductive filaments, e.g. glass, ceramic, or resin, may be pre-coated with metal to make them conductive. Whisker materials mentioned are graphite, Al 2  O 3  (which may be chromized or platinized), TiO 2 , ZrO 2 , BeO, SiC, TiC, B 4  C, TiN, A1N, WB, Si 3  N 4  or metals, and water dispersions are used with dispersing agents such as ammonium tannate. If resins are included in the dispersion an organic solvent also may be present. In examples the filaments coated are fine wires of Cu, W, and Ag. Binder resins employed are epoxy, phenolic, urea-formaldehyde and acrylamide - acrylic acid resins. As shown the filament is fed by rollers through the sides of the tank holding the dispersion, the filament being connected as one electrode and passing above a counter electrode.

Abstract: 558,678. Making generator &c. cores. FORD MOTOR CO., Ltd. June 8, 1942, No. 18613/43. Convention date, March 14, 1941. Divided out of 558,222. [Classes 83 (ii) and 83 (iv)] Coiled cores for electrical generators &c. are produced from strip by punching a number of slots at the required spacing, attaching the end of the strip to a core of the required diameter whilst the last hole punched is maintained in register with the punch and then feeding the strip step by step by indexing the core through the required angular spacing, the holes will then register approximately in radial relation to form the slots for the windings. In a modification the core diameter is less than that required by the amount that the unpunched portion between the initially attached strip and the punch will take up and this unpunched portion is cut out when the core is complete. To obtain greater accuracy in the radial register of the slots the core 36 is journalled in crossheads 42, Fig. 2, held by springs 43 against a roller 44. As the diameter of the wound core increases the core is forced downwards acting on a cam 45 to force the punch 39, 40 away from the core. The strip is guided by rolls 47 and braked at 48. By varying the cam, slots inclined to a radius may be obtained. The slots may be punched in the edge of the strip so as to be open or holes may be punched as at 50, Fig. 2, for the armature or 51, Fig. 3, for the field, forming pole pieces, the part 52 being afterwards turned or ground away.
