Abstract: The tube (60) includes first and second portions (66, 58) that each have mating spherical sections (82, 84) at adjacent ends (72, 74) of each portion (66, 68). The second portion (68) includes a spring sleeve (92) configured to surround an outlet end (72) of the first portion (66). A spring (102) is captured inside the spring sleeve (92) and secured between a retaining clip (100) and a shoulder (88) protruding from the exterior surface of an outlet end (72) of the first portion (66) to maintain fluid seals between the spherical sections (82, 84). The spherical sections (82, 84) permit slidable motion relative to each other thereby facilitating rotational and angular motion between the tube portions (66, 68). One of the two portions (66, 68) may include a telescope mount (110) to permit limited axial motion of the tube (60).

Abstract: An iso-grid composite component includes a spacer transverse to a uni-tape ply bundle, the spacer interrupted by the uni-tape ply bundle.

Abstract: A thrust vectorable fan variable area nozzle (FVAN) includes a synchronizing ring, a static ring, and a flap assembly mounted within a fan nacelle. An actuator assembly selectively rotates synchronizing ring segments relative the static ring to adjust segments of the flap assembly to vary the annular fan exit area and vector the thrust through asymmetrical movement of the thrust vectorable FVAN segments. In operation, adjustment of the entire periphery of the thrust vectorable FVAN in which all segments are moved simultaneously to maximize engine thrust and fuel economy during each flight regime. By separately adjusting the segments of the thrust vectorable FVAN, engine trust is selectively vectored to provide, for example only, trim balance or thrust controlled maneuvering.

Abstract: A fan variable area nozzle (FVAN) selectively rotates a synchronizing ring relative the static ring to adjust a flap assembly through a linkage to vary an annular fan exit area through which fan air is discharged. By adjusting the FVAN, engine thrust and fuel economy are maximized during each flight regime.

Abstract: Sections of hollow tubular pipe are joined together by one or more differentially threaded, axially mounted screw which threadedly engages internal radial flanges at the end portions of the adjacent pipes, an extension socket rotates the internal screw or screws.

Abstract: A compressible bellows surrounds a piston rod of the hydraulic cylinder of a hydraulic elevator. The lower end of the bellows surrounds a liquid receiving recess in the gland box of the cylinder and, when a sealing ring on the piston rod closes and compresses the bellows, the leaked hydraulic fluid is discharged from the recess, via a ball check valve, and a return tube to a sump.
