摘要： A compliant woven tubular seal is provided in an arcuate cavity opening through an axial face of a plurality of shroud segments in opposition to a nozzle retaining ring. The annular composite tubular woven compliant seal includes a stainless steel inner metal core surrounded by an annular layer of silica fiber. Surrounding the silica fiber is a metal foil which prevents flow past the supplemental seal. An outer wear-resistant braiding serves as a protective covering and wear surface.

摘要： In a gas turbine including a nozzle retaining ring having a first annular axially sealing surface and a shroud segment having an axial registering second surface. To minimize or prevent leakage flow between the retaining ring and shroud segments, a generally U-shaped seal having reversely folded U-shaped marginal portions is received in a cavity formed in the second surface. At operating conditions, the marginal portions seal against the base of the cavity and the first surface of the retaining ring to prevent leakage flow past the retaining ring/shroud segment interface. To install the seal, the seal body is first compressed and maintained in a compressed state by applying one or more wraps about the seal body and an epoxy is used to secure the seal when compressed in the cavity. At operating temperatures, the retention means releases the seal to engage marginal portions against opposite sealing surfaces of the shroud segments and retaining ring.

摘要： A low leakage sealing system is provided between a steam pipe and a housing comprised of a pair of shells and a nozzle box movable relative to one another. The sealing system includes large and small diameter sealing rings engaging the pipe and shells or nozzle box and a secondary sealing element disposed between the sealing rings and one of the pipe and shells or nozzle box. The sealing elements comprise frustoconical elements having curved end surfaces forming primary seals with the sealing rings and the housing. In another form, the sealing system includes annular carrier elements having radially opening cavities for receiving sealing rings engageable with the pipe and housing, respectively. The carrier elements are axially spaced from a plurality of sealing rings to provide the low leakage sealing system.

摘要： A wave energy converter (WEC) includes a float which moves generally in phase with the waves and whose up and down motion is guided by and along a spar having an upper portion and a lower portion. A power take off (PTO) device is coupled between the float and the spar for converting their relative motion into useful energy. In some embodiments, the PTO includes (a) a drum having an axis of rotation rotatably mounted within one of the float and spar; and (b) cabling means connected between the drum and the other one of the float and spar for causing the drum to rotate as a function of the up and down motion of the float. In other embodiments, the PTO system is formed using a pre-tensioned roller chain wound around sprocket wheels located within one of the spar and float with the opposite ends of the chain connected to the other one of the spar and float to cause rotation of the sprocket wheels in response to movement of the float relative to the spar.

摘要： A wave energy converter (WEC) includes a float and a spar for guiding the up and down movement of the float in response to the waves. A power take off (PTO) device coupled between the float and the spar and mounted within one of the float and spar such that the PTO includes apparatus responsive to the mechanical interaction of the float with the portion of the spar in proximity to the float for converting their relative motion into useful energy. In one embodiment the PTO includes a linear rack extending along an external portion of the spar and a linear to rotary converter, mounted within the float, including a double sided toothed belt for engaging the rack and causing rotation of the rotary converter to drive an electric generator. In another embodiment the PTO includes tires mounted within the float which rotate as the float moves up and down. In another embodiment the PTO includes a rack and pinion arrangement with one of them connected to the spar and the other mounted in the float.
