  • Patent number: 5398452
    Abstract: A metal retaining or fixing member (6) is fixed to a laminated glazing (1) with the aid of a screwed assembly. The two glass sheets (2,3) forming the laminated glazing (1) are provided with holes (15,16) before being assembled with the thermoplastic interlayer (4), in such a way that following the manufacture of the laminated glazing, they are eccentric with respect to one another. Prior to the screwing down of the assembly, the empty space separating the parts (9,18) of said assembly located within the holes 15,16) and the walls thereof is filled with curable adhesive (20).

  • Patent number: 5288527
    Abstract: A method for preparing silicon nitride films with improved properties and characterized by a limited concentration of hydrogen atoms, a high index of refraction, resistance to attack by a hydrofluoric solution, prevention of diffusion of alkalines and oxygen, and good dielectric properties such as optical gap. The process of preparation uses plasma CVD with ammonia. The invention can be applicable to flat screens, TFT transistors and functional glazings.

  • Patent number: 5186730
    Abstract: A process and a device for the bending on a frame of at least one glass sheet by gravity, the bending being performed in at least two stages during which the glass sheet or sheets undergo a deformation by gravity. In a first stage, the glass sheet or sheets are bent according to a first shape corresponding to a blank or precursor of the final shape. In a second stage, the glass sheet or sheets are bent according to the final shape. The device includes a frame 1 of which at least one part has two elements, one element forming a blank frame (2, 3, 4, 5) and another element forming a final frame (2, 3, 12, 13).
