    摘要： A bucket tip clearance control system forms part of a turbomachinery apparatus including a casing, an outer shroud coupled with the casing, and an inner shroud coupled with the outer shroud. The tip clearance control system includes a flow circuit for a thermal medium defining a flow path within the outer shroud. A thermal medium source delivers the thermal medium to the flow circuit in a predefined condition according to operating parameters of the turbomachinery apparatus. The temperature of the outer shroud is controlled according to the predefined condition of the thermal medium. By accurately controlling the temperature of the outer shroud, bucket tip clearance can be controlled and optimized during all of the various operation stages of turbomachinery.

    摘要： A plurality of arcuate, circumferentially extending leaf seal segments form an annular seal spanning between annular sealing surfaces of inner and outer casings of a turbine. The ends of the adjoining seal segments have circumferential gaps to enable circumferential expansion and contraction of the segments. The end of a first segment includes a tab projecting into a recess of a second end of a second segment. Edges of the tab seal against the sealing surfaces of the inner and outer casings have a narrow clearance with opposed edges of the recess. An overlying cover plate spans the joint. Leakage flow is maintained at a minimum because of the reduced gap between the radially spaced edges of the tab and recess, while the seal segments retain the capacity to expand and contract circumferentially.

    摘要翻译： 多个弧形的周向延伸的叶片密封段形成跨越在涡轮机的内壳体和外壳体的环形密封表面之间的环形密封件。 邻接的密封段的端部具有周向间隙以使得段的周向膨胀和收缩。 第一段的端部包括突出到第二段的第二端的凹部中的突出部。 翼片与内壳和外壳的密封表面密封的边缘与凹槽的相对边缘具有窄的间隙。 上覆盖板横跨接头。 泄漏流量保持在最小限度，因为突片和凹槽的径向间隔的边缘之间的间隙减小，同时密封段保持沿周向膨胀和收缩的能力。

    摘要： A rotary disc filter is provided with an integrated backwash and chemical cleaning system. In one mode of operation, backwash is directed through a control valve to one or more nozzles for spraying the backwash onto the filter media forming a part of a rotary disc filter. In a second mode, a chemical cleaning mode, the pump directs backwash through an eductor that induces a chemical into the inductor which is mixed with the backwash to form a backwash-chemical mixture that is sprayed onto the filter media. A control system is used in conjunction with the backwash and cleaning systems to monitor process information and/or filter media properties and to determine when to perform backwashes and regenerative cleanings in order to optimize the performance of the filter system.

    摘要： A system may include a plurality of isolators to transfer data signals across an isolation barrier, one of the signals including a clock signal. A delay circuit may be included to receive the clock signal and provide a delayed clock signal that lags the clock signal by an amount representing a delay across the isolation barrier. The delayed clock signal may be delayed by a round trip propagation delay over the isolation barrier. The delayed clock signal may be used as a reference to read data sent over the isolation barrier.

    摘要： Disclosed herein, among other things, is a stator winding temperature sensor. According to an embodiment, the sensor includes at least one sensing wire coil adapted to be connected to a stator. The sensor also includes a body, including a core material surrounding at least a portion of the sensing wire coil, and a laminate material over the core material. The body has a thickness adapted to protect the sensing wire coil. The sensor includes a lead wire adapted to connect to an external monitoring device. The sensing wire coil is electrically connected to the lead wire at a lead step portion of the sensor. In addition, the sensor includes a tab extending from the lead wire and encompassing the lead step. The tab protects the lead step and the sensing wire coil in a region where the sensor extends over an end of the stator.
