  • Method for producing a vacuum between two sheets of glass and insulating glazing
    Publication number: 20010026852
    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.

  • Linear loudspeaker
    Patent number: 6285773
    Abstract: The invention concerns a loudspeaker having an elongate parallelepiped hollow body, whereof one longitudinal surface is made up of a stretched elongate rectangular planar diaphragm. The diaphragm is suspended by its edges to the body adjacent side surfaces, and is integral with an elongate rigid inner part extending in the body longitudinal direction, and bearing a mobile electromagnetic coil, parallel to the diaphragm. The coil is arranged between two fixed magnets located along the body two longitudinal side surfaces which form, with the base of said body, polar parts. Said loudspeaker is useful as component of an active anti-noise system, associated with a double glazing.

  • Process for the manufacture of a pane of laminated glass
    Patent number: 6280547
    Abstract: The present document describes a process for manufacturing a pane of laminated glass without recourse to an autoclave. The pack of layers are composed of stacked layers (6, 7, 8), is raised to the softening temperature of the thermoplastic interlayer of the pack of layers in a preheat channel (1). The preheated pack of layers is put under vacuum in a vacuum assembly station (2) for the purpose of extracting the gas from the spaces separating the layers (6, 7, 8). After the gas has been extracted, the edge of the pack of layers, which is heid under vacuum, is mechanically compressed inside the vacuum box and is thus sealed. Finally, the pack of layers is brought to atmospheric pressure and its temperature further increased in a postheat channel (4).

  • Postforming of a shaped cord on an object
    Patent number: 6274076
    Abstract: A shaped cord (2) is postformed in the shape of a frame extruded onto a glass (1) and is slightly curved in the direction of the length of shaped cord (2). A forming mold (4) is used in a postforming operation, with lateral edges (11, 12) that are slightly above the surface of shaped cord (2). This avoids the creation of imprints in the form of lines or edges on the shaped cord, and a smooth transition is achieved between the postformed length of the shaped cord that attaches thereto.

  • Process and apparatus for laminating laminated glazing assemblies
    Publication number: 20010007270
    Abstract: A process for laminating multi-layer pre-forms into laminated glazing assemblies is provided. The pre-forms are first subjected to a vacuum in an inlet lock. Then, the pre-forms are heated to an assembly or bonding temperature in a heating chamber, while still being subjected to vacuum. Next, the pre-forms are pressed using pressing pieces in a pressing chamber, which is also subjected to vacuum. A greater pressure is exerted along the edges of the laminated glazing assemblies so as to bond the edges, preferably by using membranes. In an outlet lock which follows the pressing chamber, the laminated glazing assemblies are again vented to atmospheric pressure. An apparatus suitable for carrying out the process is also provided. The apparatus has chambers which are connected together by conveyors so as to achieve a quasi-continuous flow of material.

  • Motor-vehicle window with a structured surface in the peripheral region
    Patent number: 6253506
    Abstract: The invention relates to a motor-vehicle window (1) provided with a peripheral region which engages, at leas in places, with a sealing element (4). The motor-vehicle window (1) can be fitted both in a fixed manner and in a moveable or sliding manner. The surface of the motor-vehicle window (1) is provided, at least in the peripheral region of contact with the sealing element (4), with a structurization (2) which produces a large number of locally delimited areas of contact between the sealing element (4) and the motor-vehicle window (1). In this way, excessively high adhesion forces, with the occurrence of noise during a relative movement between the window (1) and the sealing element (4), are avoided.

  • Connecting element with an extruded seal
    Patent number: 6243990
    Abstract: An assembling element, particularly for vehicle bodywork, is provided with a fastening edge (14) onto which an elastic weatherstrip made from an extrusion-compatible elastomer is extruded. The fastening edge (14) is provided with anchoring notches (17). In a variant, the elastomer of the weatherstrip and the surface of the fastening edge (14) do not form a mutual adhesive joint and the anchoring notches (17) are provided so that the weatherstrip, which is anchored solely mechanically, can be detached if required from the fastening edge (14) and, without further processing, subsequently be refastened mechanically to the fastening edge. In a second variant, the anchoring notches (17) prevent play and make it possible substantially to enhance the connection between the strip and the edge.

  • Device for extruding a polymer frame onto a plate-shaped object
    Patent number: RE37341
    Abstract: This invention concerns a device used in the process of manufacturing an automobile pane 1 equipped with a polymer frame 52 placed on the edge of the pane 1. The frame 52 is extruded onto the pane 1 which can be moved by means of a suitable support in such a way that the edge of the pane travels through a recess in an extrusion head 25 and 40. The recess of the extrusion head 40 preferably includes a U-shaped jaw 41 straddling the edge of the pane. At the front extremity of the two half-jaws of the U-shaped jaw 41 there are disposed sealing ledges or shoes 42 and 43 which are movable perpendicularly to the surfaces of the pane and which, during extrusion, bear upon the surfaces of the pane. Alternatively, the extrusion head can include a fixed jaw where the sealing ledges or shoes slideably and sealingly contact the plate.
