Abstract: The present invention relates to a method of manufacturing electrically conducting tracks on a transparent substrate, by screen printing with an electrically conducting paste, and to the transparent substrate provided with said tracks. According to the invention, conducting tracks are formed with a width less than or equal to 0.3 mm by applying, by screen printing, a thixotropic electrically conducting paste having a ratio of the viscosity without shear stress to the viscosity under shear stress under screen-printing conditions of at least 50 and having a silver content greater than 35% and of which at least 98% of the particles which form it have a size less than 25 ?m, by means of a screen having at least 90 threads per cm, the coating of said screen being provided with slots, the narrowest width of which is equal to 0.25 mm±0.05 mm, and by subjecting said tracks to baking.

Abstract: An insulating glazed element including at least two glass sheets, separated from each other by a space and joined at their periphery by a seal, and at least one section. The glazed element has at least one heating border on at least one face of at least one glass sheet, and the border is covered by the section and joined to the section by a heat-conducting seal.

Abstract: A water-based black enamel composition capable of being deposited on a glass substrate, especially on a glass sheet. The enamel composition includes: 20 to 40% by weight of water-soluble sodium silicate and/or potassium silicate; a water-soluble base, in an amount sufficient for the pH of the composition to be at least 10.5; 5 to 25% by weight of water; 40 to 60% by weight of a metal oxide chosen from the group consisting of copper oxides, iron oxides, cobalt oxides, mixtures of these oxides, and mixtures of at least one of the oxides with chromium oxide(s); less than 10% by weight of zinc oxide; at least 10% by weight of a glass frit having a melting point below 680° C.; and less than 10% by weight of a glass frit having a Littleton point above 700° C. A glazing, especially an automobile glazing, including at least one glass sheet can have at least one of the faces of the glass sheet coated at least partially with the enamel composition.

Abstract: The invention relates to a novel method of enameling substrates comprised of glass or vitroceramic material, according to which method the enamel composition contains graphite as a component, with the aim of improving the mechanical properties of the enameled substrate and/or conferring anti-adhesive properties on the composition.

Abstract: The present invention relates to a process for manufacturing recyclable black enamels that contain at least zinc, in which process glass forming materials comprising at least bismuth, silicon, boron and manganese are melted, at temperatures greater than about 900° C., and then a glass frit comprising at least zinc is added to the mixture obtained after this direct melting. The invention also relates to zinc-based recyclable black enamel compositions.

Abstract: A method of identifying glazing that has undergone a heat treatment, consisting of fixing a substance to its surface and/or on an edge, the optical characteristic of the substance being modified at a temperature reached during the heat treatment.

Abstract: This invention concerns a pane, particularly a pane for an automobile vehicle, especially a rear window or side window, comprising a glass sheet coated on its inner face, i.e., the face intended to be towards the passenger compartment, with a network based upon an enamel composition of low emissivity and/or conductive of electricity, this network extending over, essentially, the entire area of the glass sheet corresponding to the viewing field, with a rate of coverage by the enamel composition of between 20 and 90%, and preferably between 25 and 80% of the area over which the network extends.

Abstract: The invention relates to a method for fabricating laminated glazing comprising at least one enamel layer, wherein is deposited an enamelled composition comprising an anti-adhesive frit, a medium and, optionally, a low melt point frit on a portion of the internal face of a glass sheet; the enamelled glass sheet is subjected to heat treatment at a temperature between 150.degree. C. and the glass deformation temperature, and a second glass sheet is placed on the enamelled side of the first glass sheet before simultaneous bending of the two glass sheets, final firing of the enamel taking place during bending.

Abstract: The invention relates to a process for the treatment of the periphery of a glass, more particularly an encapsulated glass, which consists of treating part of the surface of the glass by at least one silane and a composition able to form a layer having free OH groups. This process is useful for treating glass so that a resin, such as a polyurethane, upon contact with the treated glass will readily adhere and bond to the glass. The treated glass can be fitted into car body bays or openings.

Abstract: The present invention relates to an encapsulated glazing, a priming composition for treating a glazing, and a process for the adhesion of a thermoplastic profile to a glazing. The process consists of treating at least the area of the glazing to be covered with the profile with an organosilane and a composition based on a chlorinated polyolefin, the average molecular weight of which is between 1,000 and 300,000 (as determined by gel permeation chromatography), followed by encapsulating the treated glazing with a thermoplastic material, in order to form the profile. Preferably, the encapsulating step is performed by injecting.
