| 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 |
