Encapsulated Nickel Photoreceptor Substrate u.s. Patent 5,681,440. Oct. 28, 1997 W.G. Herbert et al., assignors to Xerox Corp., Stamford, Conn. A method for fabricating an electroform on a mandrel comprising applying a layer of a nickel material to a surface of the mandrel to create an electroform; separat- ing the layer of the nickel material forming the electroform from the mandrel surface; and encapsulating the nickel material on an inside diameter and an outside diameter of the electroform with another material to prevent wear of the nickel material creating a photoreceptor belt. Electroplating a Substrate Containing a Pattern u.s. Patent 5,681,441. Oct. 28, 1997 LG. Svendsen et aL, assignors to ELF Technologies Inc., Foster Ci~ Calif. A method for the deposition of a con- ductive metal onto a substrate comprising providing a substrate comprising a di- electric material and having an electro- plateable pattern on a surface thereof; wherein the electroplateable pattern com- prises a material conducive to the subse- quent deposition of a preselected metal and at least one hole extends through both the substrate and the electroplate- able pattern; providing an electroplating environment including a cathode and an anode; placing the substrate in close proximity to the cathode but such that there is no substantial electrical continu- ity between the electroplateable pattern and any electrode prior to electroplating; and electroplating to establish electrical continuity between the pattern and the cathode by way of at least one hole and deposit metal directly on the surface of the electroplateable pattern so as to pro- vide a final product.. Coated Abrasives U.S. Patent 5,681,612. Oct. 28, 1997 H.W. Benedict et al., assignors to 3M Co., St. Paul Minn. A method for preparing a flexible, end- less, seamless substrate suitable for use as a backing for a coated abrasive article com- prising inserting a fibrous material into a drum so that a major surface of the material is adjacent an interior surface of the drum, the interior surface defining a substrate width and a substrate length; placing a composition comprising an organic binder precursor material within the drum, said composition capable of solidifying to form a flexible binder; rotating the drum to evenly distribute the composition about the fibrous material and about the interior sur- face of the drum; solidifying the composi- tion to form a flexible binder such that a flexible, endless, seamless substrate is formed having an outer surface adjacent the interior surface of the drum, an inner surface opposite the outer surface and the fibrous material embedded in the binder; and providing an abrasive coating on the substrate. Process for Producinnng Decorative Multiple-Layer Coatings u.s. Patent 5,681,622. Oct. 26, 1997 B. Vogt-Bimbrich et al., assignors to Herberts GmbH, Germany A process for producing a decorative mul- tilayer coating on a substrate comprising ap- plying an aqueous self-cross-linking coating medium as a color and/or effect-inparting Circle 044 on readerinformation card Now you can Eliminate Racking of Semi-Conductors, Electronic Parts etc. by Barrel Plating with CMC Catho-Spheres. Balls are reuseable- designed for all types of metal. • Completely Copper Plated • Contains No Lacquer • Every Ball is Perfectly Round--Has No Holes • Balls are Lightweight Easily Sifted Out CMC Plastic Balls make barrel plating of small parts possible--even flat discs and interlocking items! Because CMC Plastic Balls are copper plated, they can easily be mixed with other items to be plated or burnished. The balls are not lacquered and therefore are conductive, yet CMC Plastic Balls are so light in weight that sifting is no problem at all. CMC Plastic Balls pay for themselves because they can be reused as well as refined for the gold or other precious metals used in plating PLASTIC METHODS CO. 20 West 37th St., 7th Fir. • New York, NY 10018 Phone: 212-695-0070 • Fax: 212-967-5015 E-maih [email protected] Circle 020 on readerinformationcard METAL FINISHING • JUNE 1998 157
