Polyester Coating U.S. Patent 5,646,214. July 8, 1997 M.A. Mayo, assignor to PPG Industries Inc., Pittsburgh

A coating composition containing poly- ester polymers with terminal carbamate groups and polymeric polyol derived from ethylenically unsaturated monomers.

High-Solids and Powder Coatings U.S. Patent 5,646,213. July 8, 1997 S-H. Guo, assignor to ARCO Chemical Technology L.P., Greenville, Del.

A high-solids coating, which comprises an acrylic resin that comprises recurring units of an allylic alcohol or a propoxylated

allylic alcohol, a vinyl aromatic monomer, and one or more acrylate monomers; a crosslinking agent selected from the group consisting of polyisocyanates, silanes, and melamine compounds; 20 to 50% of an organic solvent; and optionally, a pigment and a crosslinking agent.

Polyester Coating Compositions U.S. Patent 5,646,236. July 8, 1997 M.A. Schafheutle et al., assignors to Hoechst AG, Frankfurt, Germany

A polyester obtained by reacting com- pounds consisting of 5 to 50 parts of at least one linear or branched, aliphatic or cycloaliphatic, at least dihydric alcohol; 2 to 40 parts of at least one at least dibasic, aromatic carboxylic acid; 0 to 40 parts of at least one 2-alkenyldicarboxylic anhydride; 10 to 30 parts of at least one at least dibasic, linear or branched, aliphatic car- boxylic acid; 0 to 15 parts of an aliphatic, linear or branched hydroxy acid; 2 to 15 parts of an aliphatic, linear or branched polyamine having at least one primary and at least one secondary or tertiary amino group, 0 to 15 parts of a glycidyl ester of a branched, aliphatic monocarboxylic acid or

of a glycidyl ether of a branched, aliphatic alcohol; and 0 to 15 parts of polyhy- droxyamine, wherein the total parts add up to 100.

Cleaning Apparatus with On-Line Monitoring U.S. Patent 5,647,386. July 15, 1997 R. Kaiser, assignor to Entropic Systems Inc., Winchester, Mass.

An immersion cleaning apparatus suit- able for removing small particles from an article, comprising a housing including an immersion sump for receiving an article to be cleaned; inflow means for conducting fluid into the housing; outflow means for conducting fluid from the immersion sump out of the housing; first panicle detection means, coupled to the inflow means, for detecting, in a fluid flowing through the inflow means, a concentration of particles larger than a predetermined minimum size; second particle detection means, coupled to

the outflow means, for detecting, in a fluid flowing through the outflow means, a con- centration of particles larger than the pre- determined size: and reporting means for
