Patent number: 7331612Abstract: A low profile tension style flexible joint for pneumatic ducting may be useful as, for example, a joint for aircraft engine pneumatic ducting. The joint of the present invention may be used at both ends of a duct that passes high temperature (up to about 1200° F.) and high pressure (up to about 110 psia) compressor air to the combustor of a turbomachine. Some turbomachines, such as the turbo engine of a jet-powered aircraft, require a very short curved duct to fit into an unusually small aircraft installation envelope. Moreover, these installations also require those features found in conventional flex joints, including being able to support the axial load inherent in pressurized ducting systems. Unlike conventional flexible joints, such as ball joints, gimble joints and pressure compensated joints, the low profile tension style flexible joint of the present invention provides a low profile, low weight design with the ability to support the axial load inherent in pressurized ducting systems.Type: GrantFiled: March 26, 2004Date of Patent: February 19, 2008Assignee: Honeywell International, Inc.Inventors: Cristopher Frost, Richard D.

Patent number: 7063329Abstract: A fitting having an axial end with a front face having an annular groove of half dovetail configuration for receiving a seal. The annular groove having a generally flat base portion, a first and a second side wall generally perpendicular with the base portion and a mouth portion generally opposite the flat base portion. The first side wall having a proximal first portion contiguous and perpendicular with the base portion, an inwardly angled flat portion contiguous with the proximal first portion, and an arcuate portion having a first end contiguous with the inwardly angled flat portion and a second end that ends into the mouth portion. The seal having a trapezoidal cross sectional area with a first flat wall, a second wall contiguous with the first wall, a third wall contiguous with the second wall, parallel with the first wall and having a shorter length than the first wall, and a fourth wall contiguous with the third and first wall.Type: GrantFiled: June 18, 2004Date of Patent: June 20, 2006Assignee: Parker-HannifinInventors: Herbert G. Anderson, Tillman S. King, Hiralal V. Patel, Jeffry J. Beier

Patent number: 7052021Abstract: A vehicle door has inner and outer panel parts (5, 6) defining the hollow interior (16) of the door which supports a rigid frame (not shown) for a window glass (18) which slides into and out of the hollow interior (16) through a waist gap (20) formed by the upper marginal edges of the panel parts (5, 6). Inner and outer waist seals (22, 24) are mounted on the inner and outer panel parts (5, 6) for sealing against the window glass (18) along the waist gap (20). The outer waist seal (24) comprises flexible material (44), preferably extruded, which defines first and second channels (46, 48) facing in opposite directions. The first channel (46) embracingly grips the marginal edge of the outer panel part (6) to support the waist seal (24) in position. The second channel (48) embracingly grips interlocking legs of a decorative strip arrangement (56). The decorative strip arrangement (56) may comprise two separate parts (56A and 56B) presenting contrasting decorative appearances.Type: GrantFiled: April 10, 2001Date of Patent: May 30, 2006Assignee: GenCorp Property Inc.Inventor: Reimund Plottnik

Patent number: 7014195Abstract: A sealing profile between the body of a motor vehicle and a moveable window includes a receiving groove into which an edge side of the window, which side interacts with the sealing profile, enters during closure of the window, a profiled section forming the groove being subjected to deformation by the edge side until the sealing profile obtains it final shape. The profiled section has, on a side facing the window edge, a soft elastic sealing layer which is arranged on a harder supporting layer arranged behind it.Type: GrantFiled: July 19, 2002Date of Patent: March 21, 2006Assignee: DaimlerChrysler AGInventor: Thomas Graf

Patent number: 7014251Abstract: An elongate moldable, flexible material or sealing body positioned between adjacent walls of a pickup truck and canopy mounted to a pickup truck bed, to permit windows of the pickup cab and canopy to be open for communication between the cab space and the canopy space, as well as to keep out wind, rain, dust and debris. The sealing body encompassing the perimeter of the windows of the cab and canopy. The sealing body also having a width dimension greater than its thickness dimension. Further, the sealing body having the ability to rotate about its central axis to accommodate varying dimensions of gaps between the cab wall and the canopy wall. The sealing body also having a fast compression rate and a compression memory. The slow expansion rate or “slow memory” giving the added benefit of avoiding abrasion of the sealing body against the cab or canopy walls due to vibration of the cab or canopy structure.Type: GrantFiled: December 2, 2003Date of Patent: March 21, 2006Inventor: Vernon ‘Russ’ Husk

Patent number: RE39973Abstract: A metallic seal is provided that concentrates the available load over a narrow band to produce a sealing dam over a sufficient width to minimize leakage on a molecular level. The metallic seal has a first annular beam section, a second annular beam section, and inner and outer surfaces extending between the first and second annular beam sections. One of the inner and outer surfaces has an annular recess that at least partially defines an annular column section of material extending substantially perpendicular between said first and second annular beam sections thereto. The first annular beam section has a first non-sealing surface and a first raised portion with a first annular sealing surface facing in a first axial direction to contact a first member for creating a first annular sealing dam therebetween.Type: GrantFiled: June 25, 2004Date of Patent: January 1, 2008Assignee: PerkinElmer, Inc.Inventors: John Loyd Spence, Kevin R.
