Paint Detackification Process U.S. Patent 5562,633. Oct. 8, 1996 H.B. Agree and R.A. led, assignors to Berz Laboratories Inc., Trevose, Pa. A process for detackifying and coagulating paint, lacquer, or enamel in spray booths in which water is used to wash air in and to remove oversprayed paints, enamels, or IX- quers in which a water-soluble or water-dispers- ible condensation product of hexamethylenedi- amine still bottoms and ethylene dichloride in combination with aluminum chlorohydmte is added, wherein the improvement comprises adding from 0.01 to lo%, based on oversprayed paint of the condensation product of hexameth- ylene&mine still bottoms and ethylene dichlo- ride and aluminum chlorohydrate in a ratio of from 0.2.5:10 to 10: 1 to the water independently and concurrently, to form a nontacky paint sludge, and removing the paint sludge from the water by flotation. Substrate Reclaim Method U.S. Patent $562,840. Oct. 8, 1996 EA. Swain et al, assignors to Xerox Corp., Stamford, Corm. A substrate reclaim method comprising directing laser energy at a coating covering a part of an outer surface of a substrate to melt or vaporize the coating, wherein the outer surface has a shiny finish, thereby removing with the laser energy all of the coating on the outer surface and etching with the laser energy a portion of the outer surface to change the etched outer surface portion from a shiny finish to a matte fin- ish, wherein the removing of the coating and the etching of the portion of the outer surface are accomplished substantially si- multaneously. Tin Coating Composition U.S. Patent 5,562,950. Oct. 8, 1996 J.H.

An immersion method of coating a me- tallic substrate with tin comprising provid- ing an aqueous phosphate-free alkaline pH immersion tin coating composition com- prised of a source of tin ions and an effec- tive amount of a sludge control agent that is an organic chelating composition in a bath compartment wherein the tin coating com- position is comprised as tin ions (calculated as potassium stannate) l-600 g/L; organic chelating agent l-100 g/L; organic polyhy-
droxy material l-300 g/L; molybdenum ions 0.1-100 g/L.
