摘要： 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.

摘要： 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: V w V TF = k V t + R ( I ) in which Vw is the volume of the water swellable yarn after swelling upon contact with water; VTF is the total free volume in the retaining element; k is a constant≧180; R is a constant≧1.4; and Vt is the free volume per each transmission element. Advantageously, the optical cable is water-blocked and the water swellable yarn does not induce microbending effects on the transmission elements.

摘要： An apparatus (100) and method cleans a batch of pellets or granules prior to use in an extrusion process. Loose contaminants having material characteristics that are undersired for the extruded product are first removed (110) from the batch using a deduster. The deduster may also remove uncontaminated fines and fluff from the batch. Pellets that are defective or otherwise undersired for the extrusion process as well as other loose particle contaminants can then be efficiently detected and removed (120) without the risks of fines clogging the apparatus or shielding the detection process. Magnets may help remove (130) particulates of ferrous material before or after the removal (120) of defective pellets. The resulting batch of pellets helps to produce extruded materials of higher quality, such as insulation material in electrical cables.

摘要： A method of disposing a tubular covering sleeve for electric-cable joints on a supporting element may include arranging the sleeve in a rest and not yet expanded condition; causing radial expansion of the sleeve starting from axially opposite end portions; and arranging the sleeve in a radially expanded condition on the supporting element. Radial expansion of the sleeve may be carried out gradually, starting from the end portions of the sleeve toward an axially intermediate portion of the sleeve. The method of may include arranging the sleeve; arranging a pair of expanders, each at a respective end of the sleeve and at a substantially coaxial position relative to the sleeve; introducing the expanders into the respective ends of the sleeve; abutting distal ends of the expanders against each other at an axially intermediate portion of the sleeve; and arranging the sleeve in a radially expanded condition on the supporting element.

摘要： 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.
