The method includes the steps of heating the glass sheet to a temperature in a range from 1000.degree. F. to 1250.degree. F. Thereafter, a fluorine-containing compound is applied to a surface of the heated glass sheet to react therewith to form a film in which divalent oxygen atoms and hydroxyl ions on the surface of the glass sheet are replaced with monovalent fluorine atoms. In this manner, the surface of the glass sheet is brought closer to a state of electro-neutrality and the monovalent fluorine atoms form a more stable bond with soda and silica atoms of the surface of the glass sheet. Thereafter, a doped tin oxide film is applied to the film formed on the heated glass sheet to a thickness required to give the doped tin oxide film the desired conductivity and emissivity characteristics.

  • Patent number: 4596722
    Abstract: A process for manufacturing electrochromic recording materials, useful for recording signals and images, is carried out by coating a suitable substrate with a homogeneous fluid mixture of a hydrosoluble salt of a metal cathodically depositable from an aqueous solution of its ions and an initially hydrosoluble film-forming polymer resin, in water. The recording mediums of the invention are advantageous for generating images whose background and marks remain unaffected by light, heat and humidity.

  • Patent number: 4582761
    Abstract: A dispersion for coating a reflective-transmissive surface comprising a mixture of an aqueous dispersion of polyvinyl acetate resin and an aqueous dispersion of an arcylic resin. When applied to such surfaces--for example, the protective glass or plastic of an electronic screen--the coating reduces reflected glare while maintaining the quality of the image transmitted from the screen being viewed. Methods of making and using the dispersion, as well as surfaces treated with the dispersion, are also disclosed.

  • Patent number: 4547396
    Abstract: A phase-locked laser array including a plurality of closely spaced channels in the surface of the substrate with lands therebetween with the laser oscillation occurring in a cavity region over each of the channels. A broad-area electrical contact provides uniform electrical current flow to each of the lasing regions. The individual oscillators are coupled by the overlap of their evanescent optical fields. The invention also includes a method of fabricating this array which includes the steps of forming a plurality of corrugations in the surface of a substrate, forming a solution having a super-saturated growth condition for planar and concave surfaces and an under-saturated growth condition for convex surfaces, contacting the corrugated surface to the solution thereby partially melting the convex portions of the surface and forming planar lands between the concave portions of the corrugations.

  • Patent number: 4526811
    Abstract: An electrically conductive adhesive composition effective for repairing discontinuities in the electrically conducting metal lines of rear window defoggers is disclosed. The composition comprises (a) an acrylic ester polymer resin (b) a metallic pigment and (c) an organic pigment.The composition is applied as a solid solution to the interrupted section of the metal line to bridge the gap in the line and the solvent is evaporated leaving an electrically conductive bridging layer which restores electrical flow to the line. The T.sub.g of the acrylic ester polymer resin should be such that the composition does not run, sag or otherwise lose its structural integrity when the metal line is heated to an operating temperature.

  • Patent number: 4505685
    Abstract: In the manufacture of display structures--including fluorescent material displays--by means of a print process, a base material (glass or plastic material), prior to the print process, is coated with an electrically conductive layer. During the print process, a strippable coating or pigmented lacquer having the shape of the structure, is deposited onto a first layer. After the print process, the non-printed electrically conductive layer is etched away and in the case of the non-fluorescent display structure, the strippable coating is peeled off the electrically conductive layer. The invention provides an improvement in the manufacture of display structures over the hitherto conventional photographic reproduction of silk-screen printing methods, and provides display structures having sharp edges to a thickness of approximately 10 .mu.m.

  • Patent number: 4453669
    Abstract: An electrically heated glass pane includes a plurality of heating conductors (2) comprising a family of parallel conductors extending between a pair of power supply conductors (3) both disposed on and burnt-in a surface of a glass pane (1). A strip (4), of non-conductive material, covers conductors (3) and extends laterally from the edges of the conductors. The conductors (2) merge into the conductors (3) at a transitional region (7) broadened by an increasing flare so that the cross section of the region, determining the electrical resistance, is greater than the cross section of the conductors (2) providing resistive heating. A layer (12) which covers the same area as the strip (4) may be disposed below each conductor (3), directly on the surface of the glass pane (1). An opening (16) is recessed in layer (12), so that the conductors (3) are connected directly with the surface of glass pane (1).

  • Patent number: 4407847
    Abstract: A process is disclosed for the manufacture of glass sheets, particularly electrically heated backlites (EHB's). The process includes the steps of selecting a glass sheet and then applying an opaque band to a surface of that sheet. The opaque band is formed from a radiation curable paste which includes both a filler material which can fuse to the glass sheet when heated to a fusion temperature and a radiation curable material which is heat decomposable into components which are nonreactive with the glass sheet when heated to a fusion temperature. The radiation curable material is cured thereby to form a temporary bond of the radiation curable paste to the surface of the glass sheet. As an optional step in order to form an EHB, a pattern of electrically conductive material is deposited on the surface of the glass sheet. This conductive material contains at least one component which is heat fusable with the surface of the glass sheet when heated to the fusion temperature.
