    Abstract: A method of drilling one or more holes, substantially in situ, in a turbomachine casing includes locating piping including at least one vacuum head within the turbomachine casing in proximity to a hole to be drilled; drilling at least one hole in the casing such that drill chips or shavings caused by the drilling are collected in the vacuum head; and applying a vacuum through the piping to the at least one vacuum head to thereby remove the drill chips or shavings collected in the vacuum head to a location outside the turbomachine casing.

    Abstract: A directional lock for a caster. The caster has a wheel assembly including a wheel rotatable about a wheel axis and a housing for supporting the wheel. The housing defines a cavity for receiving a portion of the wheel. Also, the caster includes a stem supported by the housing and positionable in a chassis element, the wheel assembly being pivotally attached to the stem. The directional lock has an engagement portion and a base portion coupled to the engagement portion such that the engagement portion is movable relative to the base portion. The engagement portion is for engaging the wheel assembly to locate the wheel assembly in a predetermined position relative to the chassis element. The base portion is adapted to cooperate with the chassis element to maintain the engagement portion in a predetermined relation to the chassis element.

    Abstract: An outer seal assembly of a turbine rotor stage is secured within a circumferential groove of the turbine casing in such a manner as to both fix the outer seal assembly in its installed position and also provide for sealing around its outer periphery so as to thereby prevent the leakage of cooling air therearound. A plurality of arcuate elements having an angle-shaped cross sectional profile are provided to interface between radially extending arms of the outer seal assembly and the inner surface of the casing, with a locking mechanism then being applied to secure the two structures in their installed positions. Each of the arcuate elements includes a radially extending panel, a plurality of forwardly extending hooks that are disposed within a groove in the casing, and a second forwardly extending flange that engages the rear surface of the outer seal assembly arm. As the outer seal assembly arm is urged rearwardly during operation, the arcuate element is caused to rotate about a fulcrum in the circumferential groove such that a radially outer edge of the radially extending panel is urged against a casing inner surface so as to thereby enhance the sealing relationship therebetween.

    Abstract translation: 涡轮转子级的外密封组件以这样一种方式固定在涡轮机壳体的圆周槽内,以便将外密封组件固定在其安装位置,并且还围绕其外周围提供密封,从而防止 其周围的冷却空气泄漏。 提供具有角形横截面轮廓的多个弓形元件以在外部密封组件的径向延伸的臂与壳体的内表面之间进行界面,然后施加一个锁定机构以将两个结构固定在其安装位置 。 每个弧形元件包括径向延伸的面板,多个向前延伸的钩子,其设置在壳体内的凹槽内,以及第二向前延伸的凸缘,其接合外部密封组件臂的后表面。 当操作期间外密封组件臂被向后推动时,弓形元件围绕圆周槽的支点旋转,使得径向延伸的面板的径向外边缘被推靠在壳体内表面上,从而增强了 密封关系。
