Abstract: A rack has a front wall and back wall connected to a base to secure glass sheets in the rack on edge tilted toward the back wall. The front restraints are mounted on the front gate and sheet support members mounted on the rear gate to secure the sheets in position on the rack. The front gate and/or rear gate each have a pair of spaced posts with each of the posts having an end insertable in cavities provided on the base. Each of the insertion ends of the posts has a hole in one surface and an opposite sloping surface. The front gate and back gate are mounted on the base by positioning the insertion end on the edge of the cavity and tilting the gates to the vertical position to drop the insertion end of the posts in the cavities. A pin in each of the cavities passes into the hole at the insertion end of the posts to secure the gates on the base. The front restraints and sheet support members include an elongated tube having a plurality of collars rotatably mounted therein.

Abstract: Silicon-chromium cathode targets comprising 5 to 80 weight percent chromium are disclosed for sputtering absorbing coatings of silicon-chromium alloy in atmospheres comprising inert gas, reactive gases such as nitrogen, oxygen, and mixtures thereof which may further comprise inert gas, such as argon, to form nitrides, oxides, and oxynitrides as well as metallic films. The presence of chromium in the cathode target in the range of 5 to 80 weight percent provides target stability and enhanced sputtering rates over targets of silicon alone, comparable to the target stability and sputtering rates of silicon-nickel, not only when sputtering in oxygen to produce an oxide coating, but also when sputtering in inert gas, nitrogen or a mixture of nitrogen and oxygen to produce coatings of silicon-chromium, silicon-chromium nitride or silicon-chromium oxynitride respectively.

Abstract: Flexible, aminoplast-curable film-forming compositions and multi-component composite coating compositions comprising at least one pigmented or colored base coat and at least one transparent clear coat are disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a clear coat to the base coat. Both the colored base coat and the clear coat are flexible, curable film-forming compositions having an aminoplast crosslinking agent, and the base coat and optionally the clear coat has carbamate functional polymers. The flexible, multi-component composite coating compositions provide improved durability, water spotting resistance, and/or acid etch resistance, making the composite coatings particularly useful for plastic automotive parts.

Abstract: The present invention discloses a method of reducing marking of a heat softened glass sheet which results when portions of the sheet are contacted by glass sheet handling equipment. The portions of the sheet susceptible to marking are sprayed with an inert material having a melting point and decomposition temperature of at least 1200.degree. F. to form a layer that protects the sheet portion against marking from the equipment. In one particular embodiment of the invention, the lower major surface of a glass sheet is sprayed with an aqueous solution of sodium sulfate to form a layer of sodium sulfate along the glass surface which protect against marking of the glass by conveyor rolls.

Abstract: A heat processable metallic appearing coated article is prepared by coating a glass substrate with a metal-containing film such as chromium or titanium nitride, which ordinarily oxidizes at high temperature, and overcoating with a protective layer of a different metal which forms a dense oxide surface layer. The coated article is subjected to high temperature processing such as bending without losing its metallic appearance to oxidation.

Note that the percentages by weight are based upon the total solid weight of reactants used to prepare the copolymer.

Abstract: A plastic ply having at least one thermoplastic layer is positioned on a major surface of a glass ply to form a preliminary assembly, with the thermoplastic layer contacting selected portions of the major surface of the glass ply. A rigid press plate is placed on the plastic ply with the plate contacting a substantial portion of the plastic ply. Air is then removed from between the plastic and glass plies. After de-airing, the press plate is removed from the preliminary assembly and the preliminary assembly is subjected to elevated temperatures and pressures sufficient to intimately secure the plastic ply to the glass ply and form a laminate. If desired, the preliminary assembly and press plate may be heated to a temperature sufficient to soften the thermoplastic layer of the plastic ply while removing air from between the plastic and glass plies.

Abstract: This invention provides a process for electrostatically applying a coating composition onto dielectric materials which have a dielectric constant less than 4.0. In this process, a positive charge is induced onto a coating composition. The dielectric material is electrically isolated, negatively charge, or both. The positively-charged coating composition is sprayed onto the dielectric material. If the dielectric material is charged negatively, the process of the present invention further includes the step of maintaining at least a portion of the negative charge on the dielectric material while positively-charged coating particles are being sprayed thereon.

Abstract: a composition and method are disclosed whereby a substrate such as glass, plastic, metal, inorganic polymer coated substrate or inorganic coated substrate is provided with a durable non-wetting surface by treatment with a perfluoroalkylalkyl silane in a solvent which together form a composition which initially wets the surface. As the perfluoroalkylalkyl silane reacts with the surface, the remaining composition is repelled by the perfluoroalkylalkyl silane treated surface due to the difference between the surface tension of the solvent and the free energy of the treated surface, for expedient removal of the remaining composition from the treated surface.
