Coated abrasive belt
Coated Abrasive Belt U.S.Pafent 5,609,706. Mar. Ii, 1997 H.W Benedicf et a/., assignors to 3M Co., St. Paul, Minn.
A method for preparing a coated abrasive belt with an endless, seamless backing.
Sputtering Apparatus U.S.Patent 5,609,739. Mar. 11, 1997 1.Aokura et al, assignors to MatsushitaElectric lndustfial Co. Ltd., Osaka, Japan
An apparatus for performing a sputtering operation by using a rectangular target made of ferromagnetic material, the apparatus comprising an electrode in which one first permanent magnet is disposed on each side edge of a front surface of the target; polarities of the first permanent magnets confronting each other with the target interposed between the first permanent magnets are opposite to each other; one second permanent magnet is disposed on each side edge of a rear surface of the target; polarities of the second permanent magnets confronting each other with the target interposed between the second permanent
magnets are opposite to each other; and the polarity of each second permanent magnet disposed on the rear surface of the target is the same as that of the first permanent magnet disposed on the front surface of the target.
Method for Regeneration of Electroless Nickel Plating Solution U.S. Patent 5,609,767. Mar. If, 1997 E.T. Eisenmann, Albuquerque, N. M. A method for regeneration
of spent electroless nickel plating solution containing nickel ions. hypophosphite ions, an acetic acid or acetate buffer, a stabilizer, phosphite ions, sulfate ions, and water comprising passing through a chelating ion exchange resin column to remove selectively and substantially all nickel ions from the solution for retention in the resin column; treating the effluent with a base selected from the group consisting of calcium hydroxide and magnesium oxide in an amount sufficient to precipitate substantially all phosphite ions and a major portion
of sulfate ions therefrom, the precipitate being substantially free of nickel; separating the resulting solution from the precipitate: eluting the nickel ions from the ion exchange resin resulting with a solution of hypophosphorous acid; and combining the resultant solutions to obtain a regenerated plating solution.
Magnetic Paint Additive U.S. Pafent5,609,766. Mar. 11, 1997 D.J. Dee& Mendon, Mass.
A magnetic sign board comprising a substrate painted with a paint comprising paint and, per gallon of paint, from 500 to 2,000 grams ferromagnetic powder having a mixed particle size varying from 0.01 to 44 urn.
Method of Forming a Topcoat U.S. Patent 5,609,918. Mar. 11, 1997 S. Yamaguchi et a/., assignors to Kansai Painf Co. Ltd, Amagasaki, Japan
