  • Publication number: 20250058503
    Abstract: The invention relates to a method for producing an acoustic protection panel (1) for a motor vehicle, comprising a decoupling layer based on foam flakes (3) agglomerated by a heat-activatable binding agent (4), said binding agent being formed by binding fibres, said fibres comprising a core meltable at high temperature and a sheath meltable at lower temperature, said flakes being bound together by melting said sheath, so that said layer is in the form of foam flakes agglomerated by said fibres, said flakes occupying between 80% and 90% by weight of said layer, so that said fibres occupy between 20% and 10% by weight of said layer.

  • Patent number: 5520241
    Abstract: The machine for removing burrs from slabs (1) issuing from a continuous casting installation and cut to the desired length by oxygen cutting, is of the type comprising a rotor (10) carrying on its periphery self-retractable hammers (11). The rotor (10) comprises a hub (12) on which are fixed, at each end, an end flange (13) in the form of a circular collar and, between these two end flanges (13), pairs (14) of semi-flanges (15) which are in the form of semi-circular collars and are adjacent and opposed. Each pair (14) of semi-flanges (15) is evenly spaced apart in the longitudinal direction of the hub (12) and one of the semi-flanges (15) of each pair (14) is offset in this longitudinal direction relative to the other of the semi-flanges (15) of this pair (14). The invention also provides a rotor employed in this type of burr-removing machine.

  • Patent number: 5161609
    Abstract: A method and apparatus for high speed temperature regulation of elements (12) in thermal contact with a fluid contained in liquid-vapor equilibrium inside an enclosure (10) which is closed in sealed manner and which is provided with thermal insulation, temperature regulation being provided by means of an external heat source (S) imposing a reference temperature (Tc) to the fluid contained inside the enclosure (10) and causing a corresponding variation in the temperature (Te) of the elements (12) by changing the phase of the fluid. The invention is particularly applicable to performing molecular biology reactions at controlled temperature.

  • Patent number: 4781838
    Abstract: This support is constituted by a crosslinked polyvinyl alcohol hydrogel, whereof at least part of the --OH groups have been replaced by --OSO.sub.3 H groups. The crosslinked polyvinyl alcohol hydrogel comprises 70 to 95% by weight of chains derived from polyvinyl alcohol and 5 to 30% by weight of chains derived from crosslinking monomers, such as triethylene glycol diacrylate and tetraethylene glycol triacrylate.These supports can be used for the ex-vivo purification of the blood plasma in pocket 31 or 33.
