| 20100148452 | SEALING ASSEMBLY HAVING LIQUID-FILLED SEAL - A sealing assembly for a liquid conveying system includes a first structure defining an aperture, such as a pipe receiving aperture. A second structure, such as a pipe is received in the aperture. And an annular seal is disposed within the aperture for radially sealing between the first structure and the second structure. The seal includes an outer radial portion embedded in the first structure and an inner radial portion in sealing engagement with the second structure. The inner radial portion defines an internal cavity containing a substantially incompressible fluid or gel that is movable within the cavity to provide a dynamic seal with the second structure. | 06-17-2010 |

| 20110156362 | Multi-combed Self-pressurizing Pipe Coupling Seal - This self-pressurizing seal invention embodies resilient, non-corrosive and fire resistant construction with an internal pressure responsive chamber whereby fluids entering such chamber through a unidirectional fluid orifice are trapped in the internal chamber and whereby the resulting pressure differential causes outward expansion from the internal chamber to external sealing surface of multiple, pliable and conjoined ridges to form a series of redundant circumferential seals against the axial pipe surface with corresponding force to prevent the outward flow of fluids from the pipe juncture in a pipe coupling or valve. | 06-30-2011 |
| 20110266754 | IMPROVED PIPE COUPLING SEAL - A pipe coupling seal including a cylindrical elastomeric seal ( | 11-03-2011 |
| 20120086174 | SYSTEM FOR SEALING A PIPELINE SYSTEM - A system is provided that includes a fluid-tight tube, which for insertion can be introduced into the area of a gap to be sealed between two pipes of the pipeline system to be sealed. The tube is provided with a feed element for introducing a fluid, with whose aid the tube is filled and thereby increased in its volume. The feed element contains a valve, which facilitates the introduction of the fluid and at the same time prevents the outward flow via the feed element. | 04-12-2012 |
| 20120126492 | PRESSURE ACTIVATED SEAL - A pressure activated seal includes a main wall, side walls connected to the ends of the main wall, and flexible flaps connected to the side walls. The main wall, side walls, and flexible flaps define a main chamber adapted to receive fluid pressure for activating the pressure activated seal to form a seal between opposing adjacent surfaces. The pressure activated seal can be placed between concentric tubes or between adjacent plates, with one of the tubes or plates including one or more orifices leading to the main chamber to allow fluid pressure to activate the pressure activated seal to form a seal between the opposing adjacent surfaces of the tubes or plates. | 05-24-2012 |
| 20130020771 | GEL SEALING DEVICE - The present invention relates to a gel sealing device for sealing a passage of elongate parts through an opening. Such gel sealing device is preferably arranged in a housing used in telecommunication technology. The present invention solves the problem of providing a gel sealing device having improved cable access properties. The inventive gel sealing device comprises a gel sealing block ( | 01-24-2013 |
