  • Patent number: 7827825
    Abstract: A tool holder device supporting at least one tool configured to collaborate with at least one substrate positioned on edge. The tool holder device makes the tool move translationally and rotationally relative to the substrate, it being possible for the substrate to be moved translationally relative to the tool as the tool is operating. Collaboration between the tool and the substrate occurs with or without contact relative to the edge face of the substrate.

  • Publication number: 20100116416
    Abstract: The invention relates to: a method of adhering a flexible film to a substrate, in which a sufficient quantity of a liquid is disposed between the film and the substrate such that no bubbles are trapped therebetween once the film has been applied to the substrate with the aid of a scraper, said method being characterised in that the liquid does not freeze at a substrate temperature of less than 0° C.; the mutually-adhered substrate and flexible film which is characterised by the continued absence of frost in the event of the substrate and film being moved into an atmosphere in which the temperature thereof is less than 0° C., from an atmosphere having a temperature that is at least equal to 0° C. and residual moisture of at least 25%; glazing comprising same; and the applications of said glazing, including for example exposure to temperatures of less than 0° C.

  • Publication number: 20070034327
    Abstract: A method of depositing at least one functional film on at least one part of one or two faces of flat or curved substrates. The substrates are conveyed individually to a film-coating station and are advanced therein along the plane or neutral plane thereof. The film-coating station includes a film-applicator assembly including at least one axis perpendicular to the direction of advancement of the substrate and parallel to the advancement plane, at least one reel of film being mounted to the assembly. The method: conveys the leader of the film from each of the reels, which is to be applied to, and held against one face of, the substrate at a selected position, into the film-coating station; unwinds the reels such that the film can be applied in at least one strip to the advancing substrate; and cuts the film at a selected moment. Moreover, the new film leader is held to be ready to be applied at the selected position on the same substrate on a subsequent substrate.

  • Patent number: 7141282
    Abstract: An insulating glazing unit including at least two glass sheets separated by, e.g., a gas-filled cavity. An insert serves for spacing the at least two glass sheets apart and has an internal face facing the gas-filled cavity and an opposed external face, together with a mechanism for sealing the inside of the glazing unit. The insert is in the form of a substantially flat profiled strip that girds the perimeter of the glazing unit by its internal face being pressed against the edges of the at least two glass sheets and held fast by a fastening device.

  • Publication number: 20060048468
    Abstract: An insulating glazing panel including at least two glass panes separated by a gas space. A spacer serves to keep the two glass panes apart and having at least one approximately flat strip fitted at least partly around the perimeter of the glazing panel and fixed by adhesive bonding using a fastener. The strip is fitted substantially toward the interior of the panel set back with respect to at least one end face of a glass pane and is adhesively bonded against at least one internal face of a glass pane.

  • Patent number: 6656665
    Abstract: The invention concerns a method for producing a pattern on a transparent substrate, particularly a glass or glass-ceramic substrate. According to the invention, there is deposited on at least one area of one face of the substrate, a first layer of a photosensitive resin comprising at least one sensitizing agent and at least one photosensitive compound essentially composed of a polymer with an average degree of cross-linking d° such that it is able to absorb solid particles. Certain areas of said first layer are exposed to light, particularly in order to increase, in a controlled manner, the average degree of cross-linking do of said polymer so as to modulate its absorption capacity. On the first layer is deposited at least one second layer of a mineral-particle-based composition. The substrate is subjected to at least one treatment cycle, particularly in order to fix said mineral particles. The invention also concerns the substrate produced by this method and its applications.

  • Patent number: 6488796
    Abstract: A method of producing a vacuum between two glass sheets to form an insulating glazing. One of the sheets has a hole drilled in its thickness. Spacers are placed between the two glass sheets with the sealing joint being placed around the periphery of the sheets. A vacuum is created between the sheets through the hole which is then closed. The spacers are fixed on one of the sheets by bonding with a mineral compound covering at least the bonding zones on the glass sheet. The second sheet is placed on the spacers and on the peripheral sealing joint. The peripheral sealing and the bonding with the spacers are simultaneously effected by raising the temperature.

  • Publication number: 20020162278
    Abstract: A window or door has at least one folding panel or sliding door and a frame is installed in a chamber wall including an opening to be closed. The edges of the window or door are fixed on the chamber wall to be closed such that the window or door remains parallel to the wall and is not inserted into the thickness of the wall. Thus, there is no empty space to fill up, and the operation of creating a seal, which is often difficult to carry out successfully, is no longer necessary.
