  • Strip with acoustic damping properties
    Patent number: 7640808
    Abstract: A method of manufacturing an assembly including a strip inserted between two substrates, the strip being formed from at least one damping material, includes providing the two substrates; providing the strip; evaluating equivalent real stiffness per unit length K?eq of the strip and of the equivalent loss factor tan ?eq; and manufacturing the assembly by inserting a strip having an equivalent real stiffness per unit length of at least equal to 25 MPa and the equivalent loss factor of at least 0.25 between the two substrates.

  • Prefabricated set for making a cooking surface
    Patent number: 6492623
    Abstract: A prefabricated set for making a cooking top. The prefabricated set includes a glass ceramic hot plate and a frame including a part extending at the hot plate periphery and another part extending in a plane substantially vertical to the hot plate. At least one of the two frame parts includes an elastomer over-molding. A cooking top can be manufactured including such a prefabricated set.
