  • Publication number: 20190203341
    Abstract: A method is described for the production of a manufactured article (20) constituted of an elastomeric polymer substrate, in selected zones of which there are deposits of particles of nanometric size of a metal or some other compound which create a region (24) of the polymeric element having desired electrical, biocompatibility and/or dielectric properties, and such that said properties are maintained even after numerous elastic deformations of the manufactured article; the invention also relates to functionalized elastomeric manufactured articles obtained by means of said method.

  • Patent number: 6859590
    Abstract: Hybrid electrical-optical cable for overhead installations for power distribution and for telecommunications, comprising three insulated phase conductors helically wound around a supporting rope. Inside the supporting rope there is at least one optical fibre element fitted in a tubular structure which resists transverse compression, a supporting structure resistant to longitudinal tension being present around the said tubular structure.

  • Patent number: 6827884
    Abstract: Undesired and unforeseeable shrinkage may occur in a tube of plastic material containing optical fibres following its manufacture, especially during storage when the tube is wound on a reel. As a result, there may be uncontrollable variations of the ratio between length of the tube and length of the optical fibre contained therein (“excess fibre variation”). A method and equipment for limiting the excess fibre variations in a plastic tube, by stretching the tube by a predefined amount during manufacturing are described. The present invention also relates to a plastic tube subjected to a predefined stretching, a cable made of such a tube and the equipment suitable for manufacturing such a tube.
