Abstract: A hybrid bearing cylinder having a composite sleeve and a metallic jacket positioned around the composite sleeve and secured thereto. The hybrid bearing cylinder is adapted to be secured to metallic cylinder end caps by threading, welding, swaging or other metal attachment methods.

Abstract: A fluid power composite cylinder that includes conductive and resistive material as part of the composite cylinder. The conductive and resistive material to provide a sensor feature that is used to assist position sensing electronic devices in sensing the position of a piston within the cylinder.

Abstract: A composite drum having a composite drum shell and a high tension drum head at a first end and a low tension drum head at a second end.

Abstract: An antibacklash rack and pinion assembly includes longitudinally movable first and second rack members which have gear teeth thereon which mesh with the gear teeth of the pinion gear. A spring exerts a force in the same longitudinal direction of the movement of the rack members and against one of the rack members so that that rack member moves longitudinally relative to the other rack member and the teeth of that rack member are offset from the teeth of the other rack member. Thereby, opposite sides of at least one tooth of the pinion gear at all times are simultaneously positioned between and held in engagement with at least one tooth on each of the rack members to prevent backlash on movement of the teeth.
