  • Patent number: 10025004
    Abstract: This detection terminal includes a fastening element intended to be fastened in or on a support, an electrical connection component for the connection of the propagation component arranged to propagate an electrical signal along an optically invisible network, and a protection element having at least one electrically conductive portion. The protection element is movable relative to the fastening element between a first position wherein the protection element covers at least partially the electrical connection component and the electrically conductive component is in electrical contact with the electrical conductive portion and is electrically connected to the grounding component through the electrically conductive portion. In a second position, the electrically conductive component is electrically insulated from the electrical connection conductive portion and from the grounding component.

  • Patent number: 9598550
    Abstract: A method of devulcanizing vulcanized rubber is described. The method includes steps of: (a) providing at least one vulcanized rubber composition; (b) grinding the vulcanized rubber into chips or pellets; (c) mixing the ground rubber obtained from step (b) in such a way as to homogenize the form and temperature of same; (d) carrying out a non-degrading mechanical treatment on the mixed rubber at the end of step (c) to obtain a polymeric composite. Also described is a thermoplastic material and an elastomeric mixture which comprise, in the formulation of same, at least one polymeric composite obtained by this method of devulcanization.
