Patent number: 5211831Abstract: A stabilized spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards. During prolonged use of spray tin plating, the plating solution becomes saturated with cupurous thiourea complex which precipitates interfering with spray nozzles and other mechanical components. The tin plating solution is stabilized by removing portions from the reservoir before saturation is reached, selectively precipitating the thiourea complex, and returning the remaining solution back to the reservoir. The precipitated cupurous thiourea complex is redissolved in acid and either disposed of by conventional waste treatment or the acid solution can be electrowinned to reclaim copper and oxidize thiourea to form a more acceptable acid solution for waste treatment.Type: GrantFiled: November 27, 1991Date of Patent: May 18, 1993Assignee: McGean-Rohco, Inc.Inventors: Americus C. Vitale, Carl W. Reinbold, Randal D. King, John R. Dodd

Patent number: 4586785Abstract: The addition of a getter consisting essentially of reactive oxides of boron and silicon, to a melt of an alkali metal halide serves to overcome problems of unacceptable color, afterglow and hardness attributable to trace impurities present in the melt. These trace impurities are generally metals present in a concentration less than 1 part per million (ppm) parts of melt. An ingot melt-grown from charge stock treated with the getter provides high quality optical bodies such as light pipes, laser windows and scintillators. Specific problems characteristic of a scintillator ingot grown from a highly purified alkali metal halide "remelt", such as is obtained by crushing and melting portions of a melt-grown ingot, are overcome by adding to the remelt a portion of fresh powder stock in which the getter has been uniformly distributed.Type: GrantFiled: June 25, 1984Date of Patent: May 6, 1986Assignee: Harshaw/Filtrol PartnershipInventor: Carl F.

Patent number: 4522865Abstract: A method is disclosed for hot press-forging a normally frangible optically integral crystalline mass ("optical body") in a closed die, by directly pressing a surface of the mass while it is peripherally surrounded by a crystal powder the amount of which is computed from the deformation ratio desired and the geometry of the die. The crystal powder is compacted by the non-uniformly directed forces transmitted to it by the optical body, and eventually the crystal powder is sufficiently dense so as dynamically to constrain the optical body at its peripheral surface. The dynamic constraint of the optical body while it is being forged is effected in such a way as to permit deformation of the optical body without fracturing it, and, without affecting its optical integrity.Type: GrantFiled: August 18, 1983Date of Patent: June 11, 1985Assignee: Harshaw/Filtrol PartnershipInventor: Herbert Packer
