Publication number: 20130292383Abstract: A sealing apparatus includes a carrier and sealant contained by the carrier. An enclosure interface includes first and second pieces and defines one or more sealing channels that the sealing apparatus may be positioned within. The first piece defines an opening that has a perimeter sealed by the sealing apparatus. When the first and second pieces are mounted together, the sealant forms a first interface seal with the first piece and a second interface seal with the second piece. The one or more sealing channels are interconnected by one or more junction sections that include a volume of sealant. The carrier may define first and second channels that respectively contain first and second volumes of sealant. The method for making the sealing apparatus may include extruding the first and second volumes of sealant into the first and second channels.Type: ApplicationFiled: April 9, 2013Publication date: November 7, 2013Inventor: Tyco Electronics Corporation

Patent number: 8550469Abstract: A multi-layered composite gasket (10) includes three, preferably metallic cores (12, 14). A solid center core (12) is flanked on both sides by bonded paper layers (30). Perforated cores (14) mechanically interlock with each paper layer (30) through inwardly directed tangs (22). Graphite layers (26) are disposed outside of each perforated core (14) and are mechanically interlocked thereto by outwardly directed tangs (20) extending from the perforated cores (14). When using the gasket (10) material for sealing cylinder heads in internal combustion engines, a fire ring (46) may be affixed with a fire ring holder (48). The gasket (10) can be manufactured by making first and second preform sheets (32) comprised of one perforated core (14) sided with one paper layer (30) and one graphite layer (26). The preform sheets (32) are then bonded to a center core (12) using a heat activated adhesive.Type: GrantFiled: February 3, 2010Date of Patent: October 8, 2013Assignee: Federal-Mogul CorporationInventors: Wilford Dean Virgin, Deepak Ponnavolu, Michael Shirilla, Carlos Santiago, Curtis Arthur Brandt

Patent number: 8534675Abstract: A strip seal and method of configuration thereof for sealing two adjacent non-rotating gas turbine hot gas components exposed to pressure pulsations. The strip seal has at least two clamping projections distributed along discrete points of the strip seal length that extend out from a pressure face of the strip seal. The location of the projections are defined by two ratios. The first ratio, of less than 25, is the strip seal length extending free of clamping projections from any one of the ends of the strip seal to a clamping projection to the ratio of strip seal thickness. The second ratio, of less than 200, is the ratio of the strip seal length extending free of clamping projections between any two projections to the thickness of the strip seal. This seal arrangement ameliorates detrimental effects of induced resonance.Type: GrantFiled: January 27, 2010Date of Patent: September 17, 2013Assignee: Alstom Technology LtdInventors: Thomas Heinz-Schwarzmaier, Ulrich Steiger, Ulrich Rathmann
