20090053042 | METHOD AND APPARATUS FOR CLEARANCE CONTROL OF TURBINE BLADE TIP - A gas turbine including a casing and a shroud ring, the gas turbine including an attachment device rigidly attached to the casing and at least one of the shroud ring and a duct attached to the shroud ring, wherein the device allows the shroud ring to expand and contract independent of the casing and provides limited net axial growth of the shroud ring. | 02-26-2009 |
20100196164 | Turbine Coverplate Systems - In one embodiment, a coverplate may be configured to axially overlay a plurality of blade retaining slots within a wheel post of a rotor wheel. The coverplate may include a tab for radially securing the coverplate within a complementary groove of the rotor wheel and an aperture configured to align with a corresponding aperture of the turbine wheel to receive a fastener for axially securing the coverplate to the rotor wheel. | 08-05-2010 |
20100247294 | METHOD AND APPARATUS FOR TURBINE INTERSTAGE SEAL RING - A seal assembly for a gas turbine engine including a seal member and an interstage seal ring including an axially forward member coupled to a first radially inward surface of a first disk and an axially aft member coupled to a second radially inward surface of a second disk, wherein the seal ring is configured to move in an axial direction while the upstream and downstream arms are coupled to the first and second disk respectively. | 09-30-2010 |
20110243743 | ATTACHMENT ASSEMBLIES BETWEEN TURBINE ROTOR DISCS AND METHODS OF ATTACHING TURBINE ROTOR DISCS - A method of attaching two rotor discs in a turbine engine, the method comprising the steps of: forming a first rotor disc that includes a first axial extension and a disc flange; forming a second rotor disc that includes a second axial extension and a weld surface; forming a bridge, the bridge that includes a bridge flange at one end and a weld surface at the other end, and, along an outer radial surface, the bridge comprises means for sealing; attaching the bridge to the second rotor disc via welding the weld surfaces of the bridge and the second axial extension; and attaching the first rotor disc to the bridge via removably securing the disc flange to the bridge flange. | 10-06-2011 |

20080213061 | TRACK SLOT FASTENER - A fastener assembly secures loads to a track in a truck bed and is retainable within a track slot of the track. The fastener assembly may include a retainer adapted to fit at least partly within a track slot and a rotatable handle operating on the retainer, the rotatable handle being rotatable between at least an engagement position and a release position. A pressure applicator is positioned between the track and the rotatable handle, the pressure applicator having a bottom surface for applying a pressure on a top surface of the track in response to the position of the rotatable handle. The pressure applicator includes at least one projection projecting from an interior region of the bottom surface and adapted to engage a positioning scallop of the track. | 09-04-2008 |
20080253856 | TRACK SLOT FASTENER - A fastener assembly secures loads to a track in a truck bed and is retainable within a track slot of the track. The fastener assembly may include a retainer adapted to fit at least partly within a track slot and a rotatable handle operating on the retainer, the rotatable handle being rotatable between at least an engagement position and a release position. A pressure applicator is positioned between the track and the rotatable handle, the pressure applicator having a bottom surface for applying a pressure on a top surface of the track in response to the position of the rotatable handle. The pressure applicator includes at least one projection projecting from an interior region of the bottom surface and adapted to engage a positioning scallop of the track. | 10-16-2008 |
20080279649 | Track slot fastener - A slidably retainable fastener assembly for securing loads to a track is provided with a retainer adapted to fit at least partly within a track slot and a member operating on the retainer, the member being positionable in at least a first position and a second position. When the member is positioned in the first position, the member causes the retainer to disengage the track slot thereby allowing the fastener to be movable within the track slot, and when the member is positioned in the second position, the member causes the retainer to engage the track slot thereby causing the fastener to remain stationary within the track slot. | 11-13-2008 |
20110129315 | TRACK SYSTEM - A fastener assembly secures loads to a track in a truck bed and is retainable within a track slot of the track. The fastener assembly may include a retainer adapted to fit at least partly within a track slot and a handle operating on the retainer, the handle being moveable between at least an engagement position and a release position. A pressure applicator is positioned between the track and the handle, the pressure applicator having a bottom surface for applying a pressure on a top surface of the track in response to the position of the handle. The pressure applicator includes at least one projection projecting from the bottom surface and adapted to engage a positioning cutout of the track. | 06-02-2011 |
20130216326 | TRACK SYSTEM - A fastener assembly secures loads to a track in a truck bed and is retainable within a track slot of the track. The fastener assembly may include a retainer adapted to fit at least partly within a track slot and a handle operating on the retainer, the handle being moveable between at least an engagement position and a release position. A pressure applicator is positioned between the track and the handle, the pressure applicator having a bottom surface for applying a pressure on a top surface of the track in response to the position of the handle.
