  • Acoustic protective glazing for a vehicle
    Patent number: 5478615
    Abstract: An acoustic glazing intended for land transportation vehicles and including first and second glass sheets separated by an interlayer region, wherein the acoustic transmission loss differs at most by 5 dB from a figure increasing of 9 dB per octave from 800 to 2000 Hz and of 3 dB per octave above that. As examples, double glazings or laminated glazings are presented featuring an interlayer with a pronounced damping. The acoustic glazing will then operate to effectively eliminate aerodynamic noises in moving vehicles.
    Type: Grant

  • Method and apparatus for the production of a bead of organic material intended to serve as a seal and insert in a multiple glazing
    Patent number: 4957572
    Abstract: In order to form a bead of organic material having a butyl rubber base and a viscosity greater than 35000 poises, the material in a drum is heated and pumped by a reciprocating pump and delivered to an output nozzle via a conduit. A lock chamber in the conduit is delimited by valves. A variable volume chamber connected to the lock chamber or upstream of the lock chamber is able to selectively take in or discharge organic material for maintaining a constant pressure at the nozzle.

  • Method for obtaining multiple glazing and device for using said method
    Patent number: 4909875
    Abstract: The invention relates to multiple glazing, a method for obtaining the same and a device for using said method. The glazing contains two sheets of glass separated by a space of dehydrated air and maintained by a cross-braced frame, of which at least the surface in contact with the glass is a butyl and/or polyisobutylene rubber-based mastic and is covered with a peripheral injection, which adheres in a cohesive manner to the mastic of the cross-braced frame.

  • Pumping of high viscosity materials
    Patent number: 4875833
    Abstract: A vane pump in which the ports for passage of highly viscous material pumped are widely dimensioned and the clearances, in particular around the rod which carries the vane, are great. The invention applies to the pumping of materials of the type having a base of butyl rubber and/or polyisobutylene, and in general of materials exhibiting a viscosity greater than 35,000 poises.
