A nozzle for paint spray guns compris• ing a tubular body having a front end ter• minating in a conical nozzle tip and a rear end terminating in an outer thread for mounting. Spraying Device us. Patent 5,779,162. July 14, 1998 T.J. Noakes et al., assignors to Imperial Chemical Industries PLC, London An electrostatic spraying device capable of spraying liquids having resistivities of the order of 5 x 10° ohm'cm and viscosities of the order of I Poise at a spraying rate up to at least 4 cc/min. Abrasive Grain us. Patent 5,779,743. July 14, 1998 W.P. Wood, assignor to 3M Co., St. Paul, Minn. A method for making alpha alumina• based ceramic abrasive grain, comprising preparing a homogeneous dispersion by combining components comprising liquid medium, acid, greater than 60% by weight boehmite, converting the dispersion to al• pha alumina-based ceramic precursor ma• terial; and sintering the precursor material to provide alpha alumina-based ceramic abrasive grain having a density of greater than 90% theoretical. Composite Material Having Antiwear Property US. Patent 5,779,872. July 14, 1998 S. Kito et al., assignors to Toyota Jidosha KK and Nisshin Steel, both of Japan A process for producing metallic alloy particles adapted for dispersion in a matrix of a composite material having an antiwear property comprising electroplating a plat• ing layer including either tin or nickel on outer peripheral surfaces of at least one group of particles selected from the group consisting of Fe-C alloy particles and Fe• W-C alloy particles with an electric current density of from 0.5 to 5.0 A/dm 2 so as to electroplate tin in an amount of I to 15% by weight or nickel in an amount of I to 10% by weight with respect to the parti• cles; immersing the particles having the plating layer formed thereon into a ZnCI 2 'NH 4 Cl flux so as to deposit a layer of the flux on outer peripheral surfaces of the particles having the plating layer formed thereon, the flux layer having a thickness of 0.18 to 0.78 micrometer; and vacuum drying. Electroplating of Nickel on Nickel Ferrite Devices US. Patent 5,779,873. July 14, 1998 H.H. Law et al., assignors to Lucent Technologies Inc., Murray Hill, N.J. A method of electroplating nickel on a nickel ferrite device comprising providing a substrate of nickel-containing ferrite; ad• hering a metal conductor to the substrate; disposing the substrate and conductor in a nickel plating bath comprising nickel salt and an acidic buffer substantially free of boric acid for buffering the bath to a pH of 3 or less; and applying an electric current through the conductor to isotropically elec• troplate a desired thickness of nickel on the conductor. .11.
