  • Patent number: 5980666
    Abstract: A process for manufacturing a laminated glass window equipped with sealing at one or more edges, wherein the laminated glass window contains at least two glass sheets and laminated plastic placed between the two glass sheets, wherein the laminated plastic is made of at least one principal carrier sheet, having on at least one side at least one layer that reflects infrared radiation and outer layers made of one or more thermoplastic polymers; the process involving:a) forming a plate from the laminated plastic, the plate having a geometrical shape substantially the same as the glass sheets, but wherein the plate is shorter, by an offset distance, on each of one or more edges to be sealed;b) preparing a preliminary laminated sheet by positioning the plate in relation to the glass sheets while respecting the offset distance on each of the one or more edges to be sealed and removing air from between the layers formed by the glass sheets and the plate;c) filling the interstice of the one or more edges to be sealed

  • Patent number: 5939201
    Abstract: The subject of the invention is a process for depositing, especially continuously, on a glass ribbon (10) of a float line, a reflective layer (3) based on a metal whose melting point is less than or equal to the temperature at which the glass ribbon acquires dimensional stability. The deposition is carried out in a controlled atmosphere, this being inert or reducing, when the glass ribbon (10) has already acquired its dimensional stability, by bringing the surface of the said ribbon into contact with the metal (22) in pulverulent form or in molten form, the temperature of the ribbon during contacting being chosen so that the powder melts and coalesces, or so that the molten metal forms a sheet, at the surface of the ribbon, leaving a solid continuous layer when the temperature of the ribbon is at a temperature of less than or equal to the melting point of the metal.
