Apparatus For Dispensing Coatings With Multiple Components U.S. Patent 5,464,283. Nov. 7, 1995 D. Davis, assignor to Nordson Corp., Westlake, Ohio

A method of controlling the relative pro- portion of a resin and a supercritical fluid within a coating material formulation, comprising supplying the resin at a first pressure to a mixer; supplying the super- critical fluid to the mixer at a pressure that is a function of the first pressure and is in excess of the critical pressure of the super- critical fluid; combining the resin and su- percritical fluid withn the mixer to form the coating material formulation.

Cleaning and Drying Without Flash Rusting U.S. Patent 5,464,477. Nov. 7, 1995 SE. Awad, assignor to Crest Ultrasonics Corp., Trenton, N. J.

A process for cleaning contaminants from and drying a ferrous metal surface without causing flash rusting on the sur- faces comprising contacting with a solvent selected from the group consisting of ter- pene hydrocarbon, alcohol, ether, amine, ester, orange terpene hydrocarbon, hy- drotreated light petroleum distillate, ali- phatic hydrocarbon, aliphatic ester, C,, branched chain synthetic ester and aliphatic petroleum hydrocarbon; heating and ultra- sonically agitating to solubihze and dis- lodge contaminants from the surface; rins- ing with a heated, ultrasonically agitated aqeuous rinsing solution capable of pro- tecting ferrous metal surfaces from flash rusting and comprising at least one water- soluble anionic pH modifier; and drying the surface.

Oil Splitting Aluminum Cleaner U.S. Patent 5,464,484. Nov. 7, 1995 EA. Rodzewich, assignor to Betz Laboratories Inc., Jrevose, Pa.

A method for cleaning aluminum with an aqueous solution and for splitting oil in an aqueous cleaning bath comprising ap- plying to aluminum an effective cleaning

amount of the aqueous cleaning solution, which comprises an alkali metal phosphate, octylphenoxypolyethyleneoxyethanol, so- dium metasilicate, and a quatemary cat- ionic surfactant, whereby the aqueous cleaning solution provides substantially no etching of the aluminum and substantially no oxide buildup on the aluminum.

Electrolytic Recovery of Metals U.S. Patent 5,464,507. Nov. 7, 1995 0. de Nora et al., assignors to De Nora Permelec S.p.A., ha/y

A process for the electrolytic recovery of metals from solutions containing metal ions and fluorides or anionic fluorocom- plexes carried out in diaphragmless cells, comprising the steps of metal deposition and oxygen evolution characterized in that the oxygen evolution takes place at ceramic insoluble anodes, whch resist the aggres- sive action of the solutions, said anodes being made of sinterized powders of tin dioxide doped with copper oxide and anti- mony oxide or copper oxide and chromium oxide or copper oxide and praseodymium oxide.
