Publication number: 20100150715Abstract: A thermally actuated shutdown seal for a rotating shaft having a narrow annular fluid flow path surrounding the shaft. The seal surrounds the shaft with the annulus therebetween during normal operation and constricts against the shaft when the shaft slows or stops rotating. The annulus is maintained open during normal operation by a spacer interposed between opposing ends of a split ring. When the shaft stops rotating, the temperature of the annulus rises, which actuates removal of the spacer from the split ring constricting the split ring against the shaft blocking the annulus. The blocked annulus causes a pressure differential across the seal which urges a polymer seal ring, downstream of the split ring against the shaft which seals the annulus. In one embodiment, the spacer is formed of a meltable material. In a second embodiment, the spacer is removed from the split ring by a thermally responsive actuator.Type: ApplicationFiled: December 7, 2009Publication date: June 17, 2010Applicant: Westinghouse Electric Company LLCInventors: Bruce Howard, Judith Hodgson, Nick Tallos, Glenn Quinty, David Janocko, Charles Bice

Publication number: 20080042373Abstract: A sealing apparatus adapted for use in a pressure vessel such as a synthesis gas cooler. The sealing apparatus is of a segmented plate construction formed around an outer wall section of a conduit means of the pressure vessel that defines at least part of a passage for receiving effluent from a gasification process. Pressure responsive mechanisms are provided on the plate segments to maintain the pressure difference across the sealing apparatus within the acceptable operating limits as well as to permit instantaneous pressure release to prevent damage to the pressure part assembly or cage. The seal is also maintained continuously through the differential growth movement between the conduit means and the pressure vessel during heat up and cool down cycles.Type: ApplicationFiled: August 15, 2007Publication date: February 21, 2008Applicant: THE BABCOCK & WILCOX COMPANYInventors: Rickey A. Wilson, David L. Kraft, Steven R. Fry

Patent number: 7267330Abstract: A split ring seal having a structured split formed with first and second overlapping leaves, movable between a compressed state and an expanded state, and having a first bore through the first leaf and a second bore through the second leaf such that, in the compressed state, the first and second bores are mutually aligned. A method of installing one or more packing trays in a process tower comprising providing such a split ring seal carried by one or more packing trays, locking each split ring seal in its compressed state with a pin through the overlapping leaf bores, placing the packing trays in the process tower and removing the pin to allow the split ring seals to expand and seal to the process tower.Type: GrantFiled: July 6, 2005Date of Patent: September 11, 2007Assignee: Jaeger Products, Inc.Inventors: Phillip Bradley Fleming, Donald Clifton Hoyle

Patent number: 7178809Abstract: A roof weather strip for use in a convertible car is composed of a plurality of weather strip pieces corresponding to the folding of a sliding roof thereof. When the sliding roof is unfolded to form a roof of the convertible car, longitudinal end parts of adjacent roof weather strip pieces contact each other to define a continuously extending roof weather strip for sealing a side edge of the sliding roof. Each of the weather strip pieces has a base portion, a tubular door glass-sealing portion, and a sliding roof-sealing portion. In each of the longitudinal end parts, the sliding roof-sealing portion is formed tubular, and the tubular sliding roof-sealing portion and the tubular door glass-sealing portion are closed with end faces, respectively, which are provided in each of the longitudinal end parts.Type: GrantFiled: January 21, 2005Date of Patent: February 20, 2007Assignee: Toyoda Gosei Co., Ltd.Inventors: Hiroshi Kuzuya, Yoshihiro Kurosaki, Toshiya Miyashita

Patent number: 6827354Abstract: A sealing system on a first structural element having a first through-opening, including a first closing flap rotatable about an axis for closing the first through-opening. The sealing system can be coupled to a second structural element. The first closing flap is provided with a first dynamic seal on the radial outer circumference thereof. An elastic seal is provided on the wall of the first through-opening and adjacent the first dynamic seal. The inner diameter of the elastic seal is smaller in the non-operated state than the outer diameter of the first closing flap. The first structural element is provided with a second closing flap which essentially matches the first closing flap and can be swivelled together with the first closing flap. The dynamic seal can be inflated radially towards the outside by means of inner pressure when the first closing flap is in the closing position and in such a way that the elastic seal is at least partially and radially displaced towards the outside.Type: GrantFiled: July 22, 2002Date of Patent: December 7, 2004Assignee: Glatt Systemtechnik GmbHInventors: Hans-Dieter Cornelius, Heinz Pritzke

Patent number: 6802512Abstract: The inventive sealing body (DK) is comprised of a number of segments (DS1, DS2, DS3) in whose sealing chambers (DKAA, DKAM) a sealing block (DBAS, DBMS) is arranged that is made of an easily deformable, in particular, gel-like substance. Tabs (ZE) which conically extend toward one another serve to center the cable which is inserted into the sealing body (DK) and held therein. Wedges (K) which can be actuated from the outside act upon assigned pressure elements (DE), which deform the corresponding sealing block (DBAS, DBMS) thus displacing the gel-like substance in a radial direction.Type: GrantFiled: May 31, 2002Date of Patent: October 12, 2004Assignee: CCS Technology, Inc.Inventors: Thorsten Muller, Rainer M.
