| 20080256793 | Gaskets and gasket-like devices including fasteners for gaskets and a method of making and using the same - A gasket for sealing between a wall and a gasket support surface, such as between an oven housing and an oven door. The gasket includes a clip, the clip typically being made from a single strand of wire. The wire is bent into a head and a base, the base for engaging the gasket and head dimensioned for engagement with a wall for a support surface. | 10-23-2008 |
| 20090144978 | GASKET - A gasket for preventing high-temperature fluid of an internal combustion engine from leaking is located between an adjacent pair of components of the engine. The gasket includes a gasket plate made of an electrically insulating material. The gasket plate has a hole. An annular sealing member is made of a material having a higher heat resistance than the gasket plate. The annular sealing member covers part of the gasket plate that defines the hole. Therefore, the gasket is capable of, for an extended period, preventing metal components in an internal combustion engine from directly contacting each other. | 06-11-2009 |
| 20090193655 | COMPOSITE SLEEVE FOR SEALING A TUBULAR COUPLING - A composite sleeve seal for sealing a conduit connection including a body portion having collar sections spaced apart from one another to define gaps therebetween, and being interconnected to one another by link segments spanning the gaps. A seal portion interposes the collar sections in the gaps and surrounds the link segments to positively interlock the seal portion with the body portion to form the composite sleeve seal as one integral component. | 08-06-2009 |
| 20100236066 | FIXTURE AND INSPECTION METHOD FOR AN ANNULAR SEAL - A fixture assembly and inspection method by which the internal diameter and/or concentricity of a segmented annular seal can be readily inspected and optionally measured prior to final installation. The fixture assembly has at least two fixture segments supported on a base, by which an annular fixture housing is defined having an outer rim and a groove with a cross-sectional shape corresponding to a cross-sectional shape of the annular seal. The fixture assembly further includes a device or apparatus for assessing at least one dimensional characteristic of the annular seal when installed in the groove of the fixture housing and as the assessing device/apparatus travels along the interior circumference of the fixture housing. | 09-23-2010 |
| 20100242278 | INTEGRATED EXHAUST MANIFOLD AND CYLINDER HEAD GASKET - A gasket assembly for an internal combustion engine having a cylinder head gasket and an exhaust manifold gasket. The cylinder head gasket and the exhaust manifold gasket have a common layer of gasket material. The gasket assembly is formed by stamping a cylinder head gasket portion for the engine in one region of a common layer of gasket material concurrently with stamping an exhaust gasket portion for the engine in an adjacent region of the common layer of material. | 09-30-2010 |
| 20130091703 | LEAF SEAL MANUFACTURING METHOD - A process is provided for manufacturing leaf seals for effecting seals between coaxial, relatively rotating components. Each leaf seal has an annular pack of leaves which are stacked face-to-face, and are mountable to one of the components at respective root portions of the leaves. The annular pack has a pack radius at the wiping contact edges which is matched within tolerance limits to the radius of the sealing surface, The process includes: determining production parameters for the production of a plurality of leaf seals, the parameters being determined such that at least a portion of the produced leaf seals will have pack radii which violate the tolerance limit; producing the leaf seals using the determined production parameters; and modifying the pack radii of the portion of the produced leaf seals which violate the tolerance limit such that the modified pack radii match the sealing surface within the tolerance limits. | 04-18-2013 |
| 20130139386 | HONEYCOMB CONSTRUCTION FOR ABRADABLE ANGEL WING - An abradable honeycomb is integrally formed in a turbine nozzle sealing flange for engagement with a bucket angel wing to reduce the leakage of air into the turbine's hot gas path. The honeycomb is integrally formed in a turbine nozzle sealing flange using a sinker EDM method to directly sink the honeycomb into the sealing flange itself, so that the honeycomb is an integral part of the flange. For repair, an entirely new honeycomb flange can be made and welded or brazed on to the turbine nozzle. | 06-06-2013 |
| 20130167375 | APPARATUS AND METHOD FOR PROCESSING A SEALING ELEMENT LOCATED WITHIN THE HOUSING OF A GAS TURBINE - A machining or processing apparatus ( | 07-04-2013 |
| 20130199038 | METHOD OF ASSEMBLING A GAS TURBINE ENGINE - A method of assembling a seal in a horizontal split plane gas turbine engine including providing a rotor assembly including a turbine blade assembly defining a forward face and a seal ring extending axially from the forward face. The rotor assembly is positioned extending through a lower compressor casing and a lower turbine casing, the positioning including tilting the rotor assembly at an angle relative to the longitudinal axis for the engine. An upper turbine casing is positioned over the tilted rotor assembly, and the upper and lower turbine casings define a circumferentially extending seal groove. The rotor assembly is moved in an axially forward direction to position the seal ring in axially overlapping relation within the seal groove. The longitudinal axis of the rotor assembly is then aligned with the longitudinal axis of the turbine engine to further position the seal ring within the seal groove. | 08-08-2013 |
| 20140130352 | METHOD AND DEVICE FOR CHANGING A GASKET IN AN AIRCRAFT ENGINE - Method for removing a front seal plate ( | 05-15-2014 |
| 20140250688 | FLUID SEAL ASSEMBLY - A fluid seal assembly (the assembly) of the present invention is disposed between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the assembly circumscribes the shaft and lubricated the shaft and the same rotates around the axis. The assembly includes a primary seal and a wear sleeve. The primary seal includes a casing and a seal element that contacts a sealing surface on the wear sleeve. The casing includes an outer diameter and an outer seal molded onto the outer diameter. The wear sleeve has a cylindrical portion defining an inner diameter and an inner seal molded into the inner diameter of the wear sleeve. The outer and inner seals of the present invention provide improved retention in metal bores during thermal expansion and eliminate spring back effect of the assembly after installation. | 09-11-2014 |
| 20140304988 | METHOD FOR MANUFACTURING CHANNEL-TYPE BRUSH SEAL - In a method for manufacturing a channel-type brush seal of an embodiment, a cored bar is made to abut on a bundle of thin wires and the bundle of thin wires is bent at a part at which the cored bar abuts on the bundle of thin wires. Here, the cored bar is made to abut on the bundle of thin wires so that an extending direction of the thin wires in the bundle of thin wires is inclined with respect to an extending direction of the cored bar, and then the bundle of thin wires is bent, to thereby make extending directions of the bent thin wires intersect. Next, the channel is bent so that the channel sandwiches and fastens the bundle of thin wires and the cored bar at a part at which the bundle of thin wires is bent. | 10-16-2014 |
