The invention relates to an expandable device adapted to forcibly separate spaced components having generally parallel opposed surfaces defining a cavity therebetween, the expandable device having a jaw assembly with a pair of opposing jaws and actuating mechanism for opening the jaws, the actuating mechanism including a separating member configured to be driven between the jaws so as to push apart the jaws such that the jaws are openable between a contracted configuration where the jaws are receivable in the cavity to an expanded configuration where the jaws are forced apart by the actuating mechanism such that the outwardly directed surfaces of the jaws are engageable with the opposed surfaces and exert oppositely directed forces thereon. The invention also relates to an apparatus configured to carry at least one the expandable device, and an assembly comprising two of the apparatus.

The present application provides an aft plate removal tool for servicing a combustor. The combustor includes an aft plate with a central passage and a number of tubes extending through the aft plate. The aft plate removal tool includes a central screw, a lower housing attached to the central screw, the lower housing including a number of spring loaded lower housing feet, and an upper housing attached to the center screw, the upper housing including a number of spring loaded upper housing feet. The aft plate removal tool is inserted through the central passage of the aft plate such that rotation of the upper housing advances the spring loaded upper housing feet against the aft plate until the spring loaded upper housing feet push the aft plate off of the tubes.

A method and apparatus for aligning an input shaft of a wind turbine generator with an output shaft of a wind turbine are disclosed. Preferably, the method includes engaging a support flange of a wind turbine generator with an advancement structure, the support flange communicating with a securement stud associated with the support flange, and supplying a linear force on the support flange with the advancement structure, the linear force shifts the support flange in relation to the securement stud, in which the shifting of the support flange aligns an input shaft of the wind turbine generator secured to the support flange with an output shaft of a wind turbine. The method preferably concludes by rechecking the alignment of the input shaft of the wind turbine generator with the output shaft of the wind turbine.

A fluid-device connecting structure includes a first fluid device having a first connection part, a second fluid device having a second connection part, an annular seal member to connect the first and second connection parts, and a coupling member to keep the first and second connection parts in a connected state. The coupling member includes a first coupling segment and a second coupling segment, each including at one end a first hinge part or a second hinge part. The first and second connection parts each have a cylindrical outer shape. The first coupling segment has a U-like shape having an opening and surrounds the first and second connection parts over a range more than 180 degrees of an entire circumference of each of the first and second connection parts.

Method and apparatus for aligning fastener holes of two components. An alignment fixture includes two mating fixtures. Each mating fixture includes a reference plate that is aligned to the fastener holes of one of the components. Each mating fixture also includes an alignment device. The alignment devices can be aligned with the respective reference plates such that the alignment between the reference plates and the fastener holes are transferred to the alignment devices. Once aligned, the alignment devices can be temporarily attached to the respective components at locations away from the fastener holes. The reference plates can then be removed. Thereafter, the components can be brought together such that mating features on the alignment devices engage. Engagement of the mating features aligns the two components such that the fastener holes on the components are aligned.
