Abstract: A flexible hose for conveying fluids and suitable for high temperature environments, in one embodiment the hose assembly comprises a thermal paint coated nipple, a core tube, a thermal insulating layer surrounding the core tube, a cover layer surrounding the thermal insulating layer, and a vented jacket surrounding the cover layer. The thermal insulating layer may be a fibrous material such as a silica fiber. The cover layer may be thermally stable up to 750° F. or higher. The vented jacket may be a wire braid having interstices therein and formed from a corrosion resistant material.

Abstract: An actuator is disclosed that utilizes a fixed screw attached at one end to an actuator housing. A rotatable tube concentric with the fixed screw rotationally drives a nut having threads engaging the threaded shaft, such that the nut moves axially relative to the tube, upon rotation of the tube. The actuator is axially coupled to the nut by thrust bearings such that the actuator rod does not rotate with the driven member.
