|20140174136||Apparatus and Method for Applying Traction to an Elongate Element Produced by Fusing a Preform of Glass Material and Usable in a Process for Producing an Optical Fibre - Apparatus for applying traction to an elongate cylindrical element produced by fusion of an end portion of a preform of glass material, in which a traction device is capable of being connected to a portion of the elongate cylindrical element to provide traction of the elongate cylindrical element along an axis. A device for the rotation of the elongate cylindrical element applies a twist to the elongate cylindrical element about the axis simultaneously with the traction.||06-26-2014|
|20140007421||APPARATUSES FOR JOINING PAIRS OF ELECTRIC CABLES - An apparatus for applying an elastic tubular sleeve onto a splicing region between at least one pair of cables, wherein the tubular sleeve is supported in a radially expanded condition on at least one supporting element, may include axial-movement devices configured to axially move the at least one supporting element relative to the tubular sleeve at an adjustable speed, so as to cause a radial elastic shrinkage of the tubular sleeve capable of inducing an axial ejection thrust on the at least one supporting element, and counter devices configured to counteract the axial ejection thrust induced by the elastic shrinkage of the tubular sleeve.||01-09-2014|
|20120073498||METHOD AND DEVICE FOR COATING THE JUNCTION AREA BETWEEN AT LEAST TWO ELONGATED ELEMENTS, IN PARTICULAR BETWEEN ELECTRIC CABLES - A method of coating the junction area between elongated elements, in particular between electric cables. This method includes the steps of: arranging a rigid tubular support having two axially separable tubular halves; mounting an elastic tubular sleeve in an elastically radially expanded condition on an outer surface of the support; interposing a lubricating material between the support and sleeve; arranging a circumferentially continuous sealing element between the halves to prevent the lubricant from percolating between the halves; positioning the support around the junction area; and moving the halves apart from each other to enable the sleeve to collapse on the junction area. A device for coating the junction area between elongated elements and a method of making the device and a joint for electric cables.||03-29-2012|
|20110089588||WATER-BLOCKED OPTICAL CABLE AND PROCESS FOR THE PRODUCTION THEREOF - An optical cable for communication includes at least one retaining element blocked with respect to the water propagation as well as a process for manufacturing such an optical cable. The optical cable includes, in addition to the retaining element, at least two transmission elements housed within the retaining element and a water swellable yarn housed within the retaining element. The water swellable yarn is selected according to the following equation:||04-21-2011|
