atoms in its alkyl moiety; and 0.1 to 2.0% of a nonionic linear alcohol ethoxylate surfactant sufficient to reduce vapor pressure of the flood sheet; and thereafter separating and collecting the uncured paint particles from the aqueous flood sheet, whereby the uncured paint particles are reclaimed for future use.
Reclaiming Uncured Paint from a Spray Booth
Microfabrication by Localized Electrodeposition and Etching
U.S. Patent 5,641,361. June 24, 1997 W.C. Wa/sh and L,E. James, assignors to BASF Corp., Mt. Olive, N.J.
U.S. Patent 5,641,391. June 24, 1997 I.W. Hunter et al., Vancouver, B.C., Canada
A method for removing and reclaiming excess uncured paint frfm a paint spray booth comprising bringing an air stream in which uncured paint particles are entrained into contact with a flowing aqueous flood sheet within a paint spray booth such that a substantial portion of said uncured paint particles are solubilized within the flowing aqueous flood sheet and thereby removed from the stream of air and wherein the flowing flood sheet consists essentially of between 10 to 45% by weight of N-methyl pyrrolidone; between 15 to 40% of at least one alkyl glycol ether having I to 4 carbon
a directional component normal to the substrate surface, such that when the trajectory is followed a feature to substrate separation of at least several times the starting distance is generated somewhere along the trajectory; depositing the product by passing a current between the electrode and the substrate and through the solution to induce a spatially localized electrochemical reaction at the interface; and relatively moving the electrode and the substrate along the trajectory; where the depositing of the product along the trajectory, including at one or more locations several times the starting distance away from the substrate, forms the three-dimensional object.
A method for producing a three-dimensional object comprising providing a substrate having an outer conducting surface defining an interface; providing an electrode having at least a feature having at least a dimension that is small relative to the dimensions of the interface; providing a solution having a selected reactant that will, in an electrochemical reaction, deposit a desired product; positioning the feature at a starting distance from the substrate such that the feature is close to but spaced from the interface; selecting a trajectory for relatively moving the electrode and the substrate, at least part of the trajectory having
Sputtering Target U.S. Patent 5,641,389, June 24, 1997 D.P. Strauss et a/., assignors to Sony Corp., Tokyo, and Materials Research Corp, Orangeburg, IV.Y.
A target for installation in a vacuum chamber for processing a substrate by causing sputtering material to be ejected from the target onto the substrate comprising a generally disk-shaped section having two generally planar surfaces and a cylindrical outer periphery, manufactured homogeneously of the sputtering material and suf-
