20090051126 | Leak proof pipe connections and leak proofing pipe connections - A sealing ring and a method of preventing or stopping a joint leak between a pipe and a pipe fitting to minimize property damage as well as clean up costs occurring from property damage due to joint leaks by securing a sealing ring to the pipe and the pipe fitting to form a secondary joint that inhibits or prevent leakage between the primary joint between the pipe and the pipe fitting. | 02-26-2009 |
20090108544 | METHODS AND APPARATUS FOR SEALING A SLIT VALVE DOOR - Apparatus, methods and systems are provided for sealing a door of a slit valve. The invention includes a seal, adapted to extend along a perimeter of a slit valve door; and a hard stop, disposed between the seal and an outer edge of the slit valve door, and adapted to extend along at least a portion of the length of the seal, wherein the hard stop and the seal fill at least a portion of a gap between the slit valve door and a substrate sealing surface. Numerous other aspects are provided. | 04-30-2009 |
20100225072 | SEAL-RING SHAPE FORMING METHOD, SEAL-RING SHAPE FORMING APPARATUS, AND SEAL RING - A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region. | 09-09-2010 |
20100237571 | SPLIT RING SEAL WITH SPRING ELEMENT - A split ring seal assembly includes a metal seal ring having two ends defining a circumferential gap therebetween. At least a first spring element is mounted to the two ends to bias the two ends circumferentially towards each other to reduce the diameter of a circumferential inner sealing surface of the metal seal ring. | 09-23-2010 |
20120086176 | SEAL STRUCTURE USING GASKET - A gasket arranged between two sealed subject surfaces includes a plurality of segments. A recess is arranged in one of the two sealed subject surfaces at a portion corresponding to a clearance between adjacent segments. A seal is filled in the recess and deformed in accordance with the shape of the clearance between the segments. | 04-12-2012 |
20120091669 | O-RING FOR FEED ROLLER - An O-ring for a feed roller includes an O-ring body having first and second ends, which are discontinued from each other, wherein coupling surfaces in the first and second ends are capable of being coupled to each other while opposing each other in a complementary fashion; and a fastening unit fastening the first and second ends to each other such that the coupling surfaces in the first and second ends form and maintain a coupled state in which coupling surfaces oppose each other in a complementary fashion. The O-ring body has first and second storage recesses formed in corresponding opposite positions, the first and second storage recesses being engraved on outer circumferential surfaces thereof, and the fastening unit is received in and fitted to the first and second storage recesses. | 04-19-2012 |
20120098211 | SEAL APPARATUS - A seal apparatus including at least first and second adjacent seal segments, each including an elongate body with ends defined at opposing elongate body ends, to be arranged such that an end of the first seal segment joins with a complementary end of the second seal segment, the end of the first seal segment including a first male component protruding from a plane of a first seal surface to define a first female mating section about the first male component, the end of the second seal segment including a second male component protruding from a plane of a second seal surface to define a second female mating section about the second male component, the first and second male components being receivable in the second and first female mating sections, respectively, to form first and second male component overlaps in at least two dimensions. | 04-26-2012 |
20120112421 | SQUEEZE PACKING | 05-10-2012 |
20120112422 | STRIP SPLICING - The present invention concerns a method of splicing two sealing strips and a sealing strip formed by the method. The sealing strip is placed at longitudinal edges of a packaging material web, used for packaging containers for liquid foods. The sealing strips to be spliced are cut each forming an oblique edge of about | 05-10-2012 |
20120211949 | SPLIT RING SEAL WITH SPRING ELEMENT - A split ring seal assembly includes a metal seal ring having two ends defining a circumferential gap therebetween. At least a first spring element is mounted to the two ends to bias the two ends circumferentially towards each other to reduce the diameter of a circumferential inner sealing surface of the metal seal ring. | 08-23-2012 |
20120274032 | SEAL-RING SHAPE FORMING METHOD, SEAL-RING SHAPE FORMING APPARATUS, AND SEAL RING - A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region. | 11-01-2012 |
20120313330 | GASKET HAVING A CLOSED BULB AND METHOD FOR MAKING THE SAME - A molded gasket includes a base having an upper surface and a lower surface. The base includes a first portion and a second portion. A bulb portion is integrally formed with the base and extends from the upper surface of the base. The gasket further includes a dart assembly integrally formed with the base and extending from the lower surface of the base. The dart assembly includes a first barb portion extending from the first portion of the base and a second barb portion extending from the second portion of the base. | 12-13-2012 |
