Hydraulic cylinder

A combination of seals and wear guides for use in a hydraulic cylinder provides a sealed engagement between a piston rod of the hydraulic cylinder and an inner circumferential surface of a rod end of a cylinder barrel of the hydraulic cylinder through which the piston rod is axially movable. The combination includes a cylindrical metallic wear guide for seating within a first annular groove formed around the inner circumferential surface, a buffer seal assembly including an annular buffer seal cooperatively mated with an annular backup ring for seating within a second annular groove, a U-cup seal for seating within a third annular groove, a cylindrical plastic wear guide for seating within a fourth annular groove, and a triple lip wiper seal including three ringed lip portions for seating within a fifth annular groove.

Wearable electronic device

A turbine system is provided including a plurality of gas turbine engines, each having a compressor section for producing compressed air, a combustor section, and a turbine section yielding hot exhaust gas. A single, common recuperator section is shared by and operatively associated with the plurality of gas turbine engines. A first flow path within the single, common recuperator section is configured to receive compressed air produced by the compressor section of each gas turbine engine. A second flow path, separated from the first flow path and within the single, common recuperator section is configured to receive hot exhaust gases yielded by the turbine section of each gas turbine engine.
