Abstract: A process for refinishing the surface of a body of acrylo-butadiene-styrene (ABS) polymer by applying to the surface a coating material and treating the body with a solvent. The surface is cooled, together with at least the material underlying the surface, to a temperature in the range about 32.degree. F. to 40.degree. F. The surface of the body is then contacted with a solvent vapor for a time sufficient to reflow the surface but not to warm appreciably the inner layer of the body. The process avoids distortion in the refinished surface.

Abstract: The present invention provides a process for the treatment of wood material impregnated with an aqueous ammoniacal solution of water-insoluble treating chemical and having deposits of treating chemical on its surface. The process comprises submerging the impregnated wood material in the ammoniacal solution, separating the wood material from the solution and maintaining it in a moist, ammoniacal atmosphere until the wood surface is substantially free of liquid. In another aspect, this invention relates to a process for producing wood material treated with the ammoniacal solution, where the product has a clean surface.

Abstract: A tacky or sticky coating is provided on selected surface areas inside compressed gas-insulated systems to trap conducting and semiconducting particles which, if allowed to remain free, can promote breakdown between metallic parts or electrodes maintained at different potentials, or which may initiate tracking and flashover along insulating surfaces. The initially hard, dry coating is comprised of a binder component and an active component. The binder component is chemically inert to both the insulating gas within the apparatus and a solvent vapor, while the active component is capable of interacting with the solvent vapor to become tacky. The insulating coating, after exposure to the solvent vapor, becomes tacky on the surface to thereon entrap contamination particles, but the addition of the binder component prevents the coating from sagging but instead maintains its spatial position on the selected surface areas.

The invention also relates to a process for preparing a synthetic resin coated substrate web.

Abstract: A method is disclosed for coating bullets to reduce the "leading effect" thereof on the gun bores of firearms by coating each bullet, prior to loading, with a dry film lubricant composition, the lubricant composition including molybdenum disulfide dispered in a suitable carrier such as a synthetic resin dissolved in a volatile hydrocarbon solvent which evaporates on exposure to the atmosphere leaving a thin coating on each bullet. The lubricant coating has a further advantage in that it does not clog the mechanism of automated machines for loading bullets into shell casings therefor.

Abstract: Fuser members coated with a release layer of silicone rubber are treated with a solvent to remove low molecular weight siloxanes, polysiloxanes and other impurities from the silicone rubber. The solvent must be one which removes or extracts the low molecular weight siloxanes, polysiloxanes and other impurities without dissolving or otherwise adversely effecting the integrity of the silicone rubber layer coated upon a base member. Generally solvent extraction is continued until the components in the cured silicone rubber which interfer with the release properties of the rubber in releasing toner from the fuser member surface, are depleted to concentration where they do not inhibit release of the toner.

The material compatible with the coating composition may be applied to the surface of the base plate at the periphery thereof to reduce or remove the coating composition there.

Abstract: A method of applying foamed insulation to pipe is contemplated by the present invention. The pipe is moved longitudinally while being rotated about its longitudinal axis. A sprayable, foamable liquid is directed onto the surface of the pipe from a stationary location and is allowed to partially rise before a protective outer jacket is wrapped around the rising foam. The wrapping step includes application of sufficient pressure to the foam to increase the final density thereof, at the outer surface, by from 10% to 25% above the density if the foam was allowed to rise uninhibited.

Abstract: A process for flatting a glossy polyurethane surface is disclosed. The process involves the steps of forming a wear layer on a carrier member, such comprising a polyurethane-forming composition. The coated carrier member is then treated with vaporous water at a temperature below the dew point of the vaporous water so that a film of liquid water is deposited on the surface of the coating. The coating with the liquid water deposited thereon is then cured to a tack free state and then subjected to elevated temperatures where the curing of the polyurethane coating is completed.

Abstract: The method for making patterned resist masks having minimum opening dimensions. The mask is prepared initially using standard photo or electron beam lithography techniques to yield the smallest aperture dimensions consistent with the state-of-the-art. Then, the resulting mask is placed within a chamber containing an atmosphere of resist solvent vapor. The vapor is absorbed by the patterned resist mask causing controlled resist reflow which uniformly reduces the dimensions of the resist openings by an amount determined by time, temperature, resist thickness, resist type and solvent used.

Abstract: A method for coating surfaces with organic film-forming compositions, which may contain pigments or coloring matter, characterized by applying the composition to a surface or substrate while subjecting the surface or substrate to a gaseous environment whose temperature is above the boiling point of the vaporizable solvent vehicle(s) of the coating composition and removing the solvent vehicle from the applied coating in a controlled manner while in said gaseous environment. The temperatures of the environment, the surface and the coating composition are selected relative one to the other such that the film of coating will gel yet not "skin over" until the solvent vehicle has been substantially completely removed from the coating, the solvent vehicle will not be substantially lost from the coating composition until the coating has been applied to the surface, or substrate, and the application of the coating to the surface or substrate will not materially cool the surface or the environment.

C., a fluorine to carbon atom ratio of at least 1.5 and a solubility parameter of not greater than 7.

Abstract: The present disclosure is directed to a process for the production of a textile material length containing filling or bonding agents which are used in the production of synthetic leather which comprises impregnating the textile material with a thermo-sensibilized bonding or filling agent, heating said impregnated bonding or filling agent contact-free to a temperature at which the bonding agent coagulated and subjecting the textile material to subsequent treatment steps.

Abstract: Surface accumulation of crystalline treating agents, such as pentachlorophenol, and water insoluble extracted wood resins, developed during solvent removal after pressure impregnation, and readily removed by contacting the so treated wood while still in a heated condition with liquid solvent thereby causing ebullient boiling of the solvent at the surface effecting a cleaning action and dissolution of the removed crystalline agent in the body of the solvent. If the solvent is contacted with the hot surface and removed immediately following cessation of ebullient boiling no additional post treatment is necessary to remove solvent from the surface of the wood. If desired a light (short duration) post steaming, however, may be employed without adverse effect, i.e., bringing more treating agent to the surface which would again permit crystallization of the agent at the surface.

Abstract: An integrated circuit substrate surface, particularly a surface of electrically insulative material, having a pattern of elevated areas and a complementary pattern of unelevated areas is planarized by forming the photoresist pattern in registration with the pattern of unelevated areas, the photoresist pattern having narrower lateral dimensions than said elevated pattern whereby registration is facilitated, flowing the photoresist pattern to laterally expand the photoresist to cover and thereby mask the unelevated areas, and etching to lower the elevated areas which remain uncovered by the photoresist.

Abstract: A process is disclosed for manufacturing flat shaped articles made of individual fibers such as paper, woven fabric, knitted fabric and non-woven fabric impregnated with an aqueous dispersion of a polymeric binder including a sensitizing agent for causing the dispersion to coagulate at a temperature substantially below 100.degree.C. The binder coagulates at a temperature substantially below 100.degree.C. and the method includes impinging live steam on the major surfaces of the article to suddenly coagulate the binder, thereby fixing its position within the fabric and preventing its migration to the fabric's surfaces. One or more adjustable position steam nozzles are used for this purpose.

Abstract: substrates with oxidized surfaces, as e.g. SiO.sub.2 layers on silicon semiconductors and aluminum surfaces, are wetted with an organic silicon compound, for example, .gamma.-aminopropyltriethoxysilane dissolved in an organic solvent such as trichlorotrifluoro ethane. The solvent is then removed in a dry atmosphere. The evaporation step can be carried out by suspending the substrate in volvent vapor over a supply of refluxing solvent while cooling the solvent vapor such that fresh, dry solvent vapor continuously passes along the substrate and absorbs traces of moisture. Subsequently, a coating is applied from a solution of a polyamido carbon acid formed of pyromellitic acid anhydride and an aromatic amino component and the polyamido carbon acid is heated to form an adherent layer of polyimide.
