Goetz, Sarver; Kurt A. Humbert, Pittsburgh; Karl F. Schimmel, Verona; Karen A. Barkac, Murrysville; Simion Coca, Pittsburgh; Joanne H. Smith, Allison Park.

The present invention relates to thermosetting coating compositions containing flow control agents. Particularly, the invention relates to such compositions containing flow control agents that are low surface tension (meth) acrylate containing block (co)polymer compositions prepared in a controlled radical (co)polymerization process.

University of Pittsburgh for "Cationic cholesteryl derivatives containing cyclic polar groups." Inventors were Hemant M. Deshmukh, Pittsburgh; Leaf Huang, Wexford.

This invention relates to cationic lipids and their use in delivering biologically active substances to cells. In particular, the invention relates to novel cationic cholesteryl derivatives containing cyclic polar groups and the use of these derivatives to deliver biologically active substances to cells and to transfect nucleic acids into cells.

PPG Industries Ohio Inc. for "Multicomponent composite coating composition and coated substrate." Inventors were Dennis L. Faler, Pittsburgh; Djurdjica Glas, Stuttgart, Germany; Hans-Dieter Hille, Bergisch Gladbach, Germany; Michael Jager, Bornheim, Germany; Walter Metzger, Denkendorf, Germany; Kurt G. Olson, Gibsonia; Edward S. Pagac, Portersville; Daniel E. Rardon, Gibsonia; Shanti Swarup, Allison Park.

The present invention relates to aqueous coating compositions and, more particularly, to their use in multicomponent composite coating compositions as primers, pigmented or colored basecoats and/or transparent topcoats which provide good smoothness and appearance in automotive coating applications.

PPG Industries Ohio Inc. for "Laminated transparency." Inventors were C. Edward Brown, Altoona; William S. Cunningham, Springdale; Michael T. Fecik, Pittsburgh; Vaughn R. Imler, Tyrone; Alana R. Zajdel, Lower Burrell; William B. Zimmerman, Pittsburgh.

This invention relates generally to the manufacture of laminated transparencies, e.g., laminated automotive transparencies, and, more particularly, to shaped, laminated automotive sidelights and to methods of making the sidelights.

Bayer Corp. and Leroy Payne, Molt, MT for "Method for producing a polyurethane/geofabric composite." Inventors were Peter H. Markusch, Sannibel, Fla.; Ralf Guether, Pittsburgh; LeRoy Payne, Pittsburgh.

The present invention relates to a method for impregnating at least one geofabric with a liquid solidifiable polyurethane composition, conforming at least one polyurethane-impregnated geofabric to a surface and allowing the liquid solidifiable polyurethane composition to cure to form a polyurethane/geofabric composite.

Kop-Coat Inc. for "Synergistic combination of insecticides to protect wood and wood-based products from insect damage." Inventors were Raymond Bender, Gibsonia; Alan S. Ross, Pittsburgh; Hans A. Ward, Wexford.

This invention relates to a synergistic combination of two insecticides, boron-containing compounds and synthetic pyrethroids, which when used in combination, give a synergistic result in providing improved resistance to insect attack on wood treated with this combination. Wood treated with this combination, and a method of treating wood, also is included in the present invention.

Respironics Inc. for "Apparatus and method of providing high frequency variable pressure to a patient." Inventors were Patrick W. Truitt, Pittsburgh; William A. Truschel, Monroeville; Bernie F. Hete, Trafford; Michael Bobeck, Sarver; Michael W. Haas, Trafford.

The present invention pertains to an apparatus and method of providing high frequency variable pressures to an airway of a patient, and, in particular, to an apparatus and method of providing high frequency variable pressures in which a valve generates the pressure oscillations in the delivery of gas to or from the patient independent of patient effort.
