Abstract: A cleaning methodology for cleaning a paper path surface upon which paper travels within a printing apparatus. The cleaning device is a flexible substrate sheet having a first side and a second side, with the first side coated preferably in its entirety with an exposed adhesive having a tack strength between about 0.0002 and about 0.12 pound force-square inch.

Abstract: An object (12) may be cleaned by CO.sub.2 reduced ESD by directing a first water mist (23) at a surface (14) of the object while imparting a relative motion between the object board and the mist to form a film of water on the object surface. As the relative motion is imparted between the board and the first mist (23), a second water mist (32) is injected into a stream (30) of solid CO.sub.2 particles (27) directed at the object surface downstream of the first mist. Water droplets in the second mist in the second mist combine with the CO.sub.2 particles to create carbonic acid that disassociates into charged ions that increase the conductivity of the water film, allowing for increased charge dissipation, thus reducing the incidence of ESD.

Abstract: A method of removing plastic ink film from a sheet of copy paper by preheating the paper sheet in a preheating chamber to loosen the plastic ink film from the paper sheet followed by contacting the heated paper sheet with an adhesive surface by pressing the adhesive surface against the heated paper sheet, fusing the plastic ink film to the adhesive surface and then peeling the heated paper sheet from the adhesive surface so that the plastic ink film is removed from the paper sheet.

Abstract: Relatively thin flexible sheets of oleophilic, hydrophobic substrates, such as polyethylene film, are used as the basis for sorbent media in novel methods for defending against oil spills. Exhibiting the combination of a high storage density and a high affinity for oil, substrates according to the invention are intended for deployment on sensitive areas of open water or shoreline as a first line of defence against approaching oil slicks, or for early assistance in the containment of oil near the source of a spill.

Abstract: A powder coating booth has a bottom surface on which powder is collected and from which the powder should be removed. Two scrapers are supported on a transport device which move them together. Each scraper is movable from its respective end of the booth toward a central collection region. Since the scrapers are moved simultaneously, one is moving toward the collection region while the other is moving away.
