Abstract: This invention pertains to a procedure for making reflecting plates, having reflective film, to be used for vehicle licenses and identification, whose identification characters are raised or depressed and then blocked with a paint or substance, using rollers to prevent them from being painted when the entire background or front of said plate, which is opaque, translucent or less reflective than the identification characters on said plate, is painted, and the product resulting from said process.

Abstract: The disclosure relates to a method of forming a multilayer interconnection structure. The structure is a laminated body having a first conductive layer, a first insulating layer, a second conductive layer and a second insulating layer in an ascending order. In the method, firstly, a through-hole is formed on the laminated body so as to expose a surface of the first conductive layer and two opposed surfaces of the second conductive layer. Then, the two opposed surfaces of the second conductive layer is masked with a masking film, so as not to deposit thereon a metal which has a strong and selective adhesion on the first and second conductive layers. Then, the metal is deposited on the surface of the first conductive layer by a chemical vapor deposition method so as to fill a lower portion of the through-hole with the metal. Then, the masking film is removed so as to expose the two opposed surfaces of the second conductive layer.

Abstract: The covering (13) of a printing roller (10) for transferring hot glue printing material from a printing block to the front panel of a display consists of cast silicone rubber without any silicone fluid. The use of silicone-fluid-free silicone rubber ensures that the printing materials will adhere well to the panel even in a sequence of printings, because the adhesion properties of the panel will not have been reduced by silicone fluid that would otherwise have been transferred from the roller to the panel. Although the roller covering is devoid of silicone fluid as stripping agent, the printing material nevertheless separates readily from the covering, because the latter is cast and therefore has a very smooth surface.

Abstract: A method of forming friction-reducing and wear-resistant silver/molybdenum coating material by co-depositing quantities of silver and molybdenum simultaneously forming nano-crystalline binary mixtures on iron surfaces.

Abstract: An aluminum alloy preform having an outer surface portion prelubricated with a film of a water-microemulsifiable lubricant composition comprising an oil, an anionic surfactant, a non-ionic cosurfactant, and optionally a C.sub.10 -C.sub.36 mono- or dicarboxlyic acid. The lubricant composition is dissolved in an organic solvent (preferably hexane) and applied to the preform. The solvent evaporates, leaving a water-microemulsifiable lubricant film. The lubricated product is readily washable with water to microemulsify the lubricant film into a microemulsion.

Abstract: A method for coating articles, such as gas turbine blades, with a coating of variable thickness by securing a shield having one or more holes extending therethrough to the article thereby defining a shielded portion of the article, exposing the article and shield to a metal-bearing gas which is circulated around the article to deposit a metallic coating thereon, wherein the circulation of the gas adjacent the shielded portion of the article is restricted by the presence of the shield, thereby producing a substantially thinner coating on the shielded portion of the article than on the unshielded portion.

Abstract: A spray coating apparatus (10) for applying a paint composed of a controlled mixture of two liquid components. A first gear pump (32) is disposed in a spray booth (30) and pumps the first component to an applicator (14). A second gear pump (36) in the spray booth (30) pumps the second component to the applicator (14). A manifold (44) is disposed between the two gear pumps (32, 36) and the applicator (14) for converging the two paint components.

Abstract: A method for producing an oxide superconducting connecting line includes initially coating a line with at least one layer of a crystalline or amorphous metal alloy forming a superconductive oxide. The line is subsequently heated to a temperature below the melting temperature of the oxide. A gas containing oxygen is simultaneously brought into contact with the accessible surface forming an oxide film which is superconductive upon cooling. When the oxide film is damaged at a certain location, the still-undamaged layer is exposed to the oxygen-containing gas and the line is heated at the damaged location. A superconducting film is again formed. A combination superconducting connecting line and an apparatus for producing the superconducting connecting line is also disclosed.

Abstract: An apparatus for applying a heat responsive melt sealant to the side edge of a carton, such as a gable-top liquid carton prior to folding the carton into its tubular form. The apparatus forces the sealant to flow evenly along an edge of the carton to be sealed and confines the sealant adjacent to the edge. The apparatus has a reverse C-shaped channel through which the carton blank edge is fed and a duct opening in the bight portion of the channel through which the sealant is fed onto the carton blank edge. In the process of the invention, after the heat responsive melt sealant is applied to the interior edge of the carton blank, the latter is conveyed to a heat station where the heat responsive melt sealant is cured preparatory to final erection of the tubular carton.

Abstract: A method of covering stress cracks in drywall, plaster or the like which comprises the step of spraying an aerosol composition which air dries to a film which has an elasticity of at least 100 percent elongation. The aerosol composition comprises a propellant, a solvent, and a concentrate including film-forming copolymers and resins. To prevent any apparent reoccurrence of the crack, the aerosol composition is pigmented. The pigmentation of the aerosol composition is such that, when the film is stretched, the outline of any reappearing stress crack will not become noticeably visible either through the film or because of marked differences between the coloration of the stretched film and of any topcoat of paint on adjacent surfaces.

Abstract: An efficient spray displacement tin plating process of copper printed circuit innerlayers is disclosed for the manufacture of multilayer printed circuit boards. The displacement tin plating solution is stabilized and replenished by incorporating free tin metal in the plating solution reservoir. Unwanted tin(IV) ions which are produced by aerial oxidation during the spray process, are reacted with tin metal in the reservoir to produce sufficient tin(II) ions to compensate for losses due to plating, oxidation and the like. Not only is the plating bath stabilized, but its useful life is extended dramatically.
