Abstract: An electrochromic system for controlling the color state of an electrochromic pane. The charge needed to obtain the desired color is determined from the discharge potential of the system and the coloration set-point. An integrator measures the charge passing through the system and compares it to the charge to be transferred. This charge is measured by a differential amplifier which compares a discharge potential measured by a capacitor with a selected color set-point.

Abstract: In a method for bending glass plates, the glass plates are heated in a horizontal position in a continuous furnace (1) to the bending temperature and in a following bending chamber (5) are pressed by an upwardly flowing hot gas stream against a convex bending mold (7) positioned above the conveying plane. The bent glass plates (3') are placed on a displaceable shaping ring (13) and transferred with the latter into a following cooling station (16). The glass plates (3) are raised from the conveying roller train (2) of the continuous furnace (1) by a suction plate (3) are positioned relative to the transfer ring (28) on the latter. With the aid of the transfer ring (28) the glass plates (3) are transferred into the bending chamber, where in the end position of the transfer ring (28) they assume the desired end position relative to the bending mold (7).
Abstract: A solution of an organic compound of aluminum and tin or titanium is formed from, respectively, a nonhydrolyzable aluminum chelate and at least one organic compound of tin or a titanium chelate or alcoholate. The solution is then sprayed onto a heated glass substrate, thereby thermally decomposing and oxidizing the solution on the heated glass substrate to form, respectively, a layer of aluminum and tin or titanium oxides on the glass substrate. A semiconductive layer can be deposited upon the aluminum/tin or aluminum/titanium layer to form a coated glass structure which is useful for buildings or automobiles.
Abstract: The invention has as its subject a glass substrate provided with a conducting, low-emissivity transparent functional film, based upon metal oxide or oxides, on which is deposited an "outer" coating, the optical thickness of which is approximately one-quarter of the mean wavelength of the visible range, and preferably centered on 550 nm. In addition, an intermediate coating is provided between functional film and substrate, said coating having an optical thickness of from 50 to 100 nm, and preferably from 50 to 75 nm.

Abstract: An apparatus for bending/tempering glass sheets raised to their softening point with a view to their bending and tempering includes an upper plate mold and a lower annular mold on which the glass sheets are deformed, and with respect to which the edge of glass sheets move as a result of their deformation, particularly by horizontal pressing between the upper bending mold and the lower mold. The bent sheets are thermally tempered in air on the same annular mold in a tempering station. This annular mold is designed in such a way that its contact surface with the glass sheets at the start of their deformation on the mold, being located on the outer periphery of the mold, is appropriate for the mark-free displacement of the glass on the mold and in particular for pressing, and so that at the end of displacement, and in particular at the end of pressing, the contact surface located on the inner periphery of said mold is appropriate for tempering.
Abstract: The subject of this invention is a method of making a curved glass pane of laminated glass, such as an automobile windshield, in which one of the two single glass sheets is provided, on the surface bearing against an intermediate layer, with a film of a baking finish. The baking finish is applied onto the inner face of the single glass sheet intended for the outside. The glass sheet, provided with the dried baking finish (i.e., a colored film), is laid, with the film upwards, onto the single glass sheet intended for the inside. The pair of glass sheets, in this arrangement, is prebent on a bending frame with simultaneous baking-in of the colored film. Subsequently, the two glass sheets are transposed and, in this transposed arrangement with the colored film on the inside, are finally bent in a second bending operation on a bending frame corresponding to the final shape of the outer sheet.
Abstract: A method of depositing a coating on a glass substrate by pyrolysis, which entails:superheating a face of a substrate intended for receiving a coating to a temperature higher than or equal to the softening temperature of the substrate, and depositing the coating without any homogenization of the temperature throughout the substrate to a value going above the softening temperature of said substrate being produced within the thickness of the substrate.
Abstract: The invention describes a glazing equipped with an extracted profile on which or in place of which is cast a complement, which is connected to the profile. The procedure makes it possible to replace part of the profile which is difficult to produce by extrusion or to add to it foreign elements such as fastenings or various accessories.
