| 20080295910 | Pre-Tensioned Sealing Means Arrangement - The present invention regards a barrier plug system ( | 12-04-2008 |
| 20110297264 | Hydraulically installed tube plug, tube plug installation tooling, and installation system and method - A hydraulically installed tube plug with or without O.D surface enhancements and plug installation tooling, high pressure fluid system and method. The invention stops leaks in tubes with a plug that utilizes controlled high pressure fluid within the plug itself to radially expand the plug in place. Other plugs and plugging systems rely on mechanical methods for setting the plugs in the tubes with little or no control on the radial pressure applied to the tube. This lack of radial pressure control can result in a tubesheet ligament being over stressed (plastically deformed) or not enough pressure applied to stop the leak. | 12-08-2011 |
| 20100032043 | Arrangement for sealing an end section of a tube or of a tubular vessel - The invention relates to an arrangement for sealing an end section of a tube or of a tubular vessel with a sealing plate arranged pointing toward the tube, and a front plate arranged pointing away from the tube. A peripheral seal is arranged in the outer region of the plates and is disposed at least partly between the sides which point toward one another. The invention provides an arrangement for sealing an end section of a tube or of a tubular vessel, which prevents passage of a medium either out of or into the vessel. This is achieved by virtue of the arrangement, where on at least one of the sides of the plates pointing toward one another in the sealing region, there is a projection which, when forced by pressure onto the sealing plate, brings about a deformation of the seal in the direction of the inner wall of the tube or tubular vessel. This results in an increase in the sealing action, and by virtue of the tensioning element with which the deformation of the seal, which arises through the pressurization can be maintained in the unpressurized or low-pressurized state of the sealing plate. | 02-11-2010 |

| 20110011481 | DEPLOYING A CHEMICALLY-INFLATABLE BAG WITH AN UNFURLING ACTION - Embodiments provide an apparatus and methods for providing a nonlabor-intensive process for preventing backfill entering, or environmental factors eroding, a cavity formed in the ground. Preventing cavity degradation involves constructing a chemically-inflatable bag that separates two or more chemical reactants by creases and cylindrical coils formed in the chemically-inflatable bag. The creases typically act as watertight releasable seals that separate the chemical reactants while the cylindrical coils resist unintentional compromise of the releasable seals. However, the cylindrical coils are designed to give way upon the user applying an unfurling action on the chemically-inflatable bag; thus, furnishing a passageway for the chemical reactants to intermix and initiate a chemical reaction. The chemical reaction produces carbon dioxide as a by-product, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity. | 01-20-2011 |
