摘要： A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine (such as combustor casing segments). The seal includes a generally imperforate foil-layer assemblage which is generally impervious to gas and is located in the leakage-gap. The seal also includes a cloth-layer assemblage generally enclosingly contacting the foil-layer assemblage. In one seal, the first edge of the foil-layer assemblage is left exposed, and the foil-layer assemblage resiliently contacts the first member near the first edge to reduce leakage in the "plane" of the cloth-layer assemblage under conditions which include differential thermal growth of the two members. In another seal, such leakage is reduced by having a first weld-bead which permeates the cloth-layer assemblage, is attached to the metal-foil-layer assemblage near the first edge, and unattachedly contacts the first member.
摘要翻译： 一种用于大致密封燃气轮机间隔开的第一和第二构件之间的气体路径泄漏间隙的气体通道泄漏密封件（例如燃烧器壳体段）。 密封件包括通常无孔的箔层组合件，其通常不透气体并且位于泄漏间隙中。 密封件还包括通常围绕箔层组合接触的布层组合件。 在一个密封件中，箔层组合件的第一边缘被暴露，并且箔层组合件弹性地接触第一边缘附近的第一构件，以减少布层组件的“平面”中的泄漏，条件包括 两个成员的差热发展。 在另一个密封件中，通过具有渗透布层组合件的第一焊道，附着到第一边缘附近的金属箔层组件，并且不附着地接触第一构件，这种泄漏被减小。

摘要： A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat is mounted to the body at the intersection of the flow passage and the cavity. A gate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The end faces between a seat pocket and the seat are hard-coated and smooth-finished to provide sealing when mated. The hardcoated pocket and seat sealing surfaces extend the life of the valve by eliminating the need for an elastomeric seal of limited life.

摘要： A gas turbine subassembly having a stator, a rotor, and an annular brush seal which is attached to the stator and whose free end is in line-to-line contact with a first circumferential portion of the rotor's outside surface during a first rotation/load state (such as a full-speed/full-load state of a power-plant gas-turbine rotor). A longitudinally-adjoining second circumferential portion (such as a groove) has a smaller diameter than that of the first circumferential portion. The rotor and stator together undergo a predetermined differential thermal movement when the rotor transitions to a second rotation/load state (such as a turning-gear/no-load state). During such movement, the free end of the brush seal moves radially inward and longitudinally across the second portion, preferably without any contact, to minimize or eliminate brush seal wear.
摘要翻译： 一种具有定子，转子和环形刷子密封件的燃气轮机子组件，其在第一转动/负载期间附接到定子并且其自由端与转子的外表面的第一周向部分线性接触 状态（例如发电厂燃气轮机转子的全速/满载状态）。 纵向邻接的第二圆周部分（例如凹槽）的直径小于第一圆周部分的直径。 当转子转变到第二转/负载状态（例如转向齿轮/空载状态）时，转子和定子一起进行预定的差动热运动。 在这种移动过程中，刷子密封件的自由端径向向内和纵向移动穿过第二部分，优选地没有任何接触，以最小化或消除刷子密封件磨损。

摘要： A locomotive diesel engine test assembly generates a once-per-cycle signal phased to the top dead center of a predetermined piston in its cylinder. A locomotive diesel engine crankcase door is hermetically attached to the crankcase so as to cover a camshaft located therein. An outer tube extends through and is hermetically and fixedly attached to the crankcase door, and an inner tube extends through and is hermetically and pivotably attached to the outer tube. A proximity sensor is attached to the inner tube and positioned near and generally perpendicular to the camshaft. A marker is attached to the circumference of the camshaft and is detectable by the proximity sensor once per revolution of the camshaft.
