Abstract: A reinforced pipeline liner designed to facilitate installation and systems and methods for producing and installing a reinforced pipeline liner. A reinforced pipeline liner can comprise a body portion having a layer of matrix material, the layer having an inner surface and an outer surface, and a plurality of interspersed reinforcement structures embedded within the body portion. The reinforcement structures are positioned between the inner surface and outer surface of the layer and circumferentially offset from the other reinforcement structures. Additionally, the body portion may have multiple thicknesses.

Abstract: A hybrid bearing cylinder is formed to include a composite sleeve and a metallic jacket positioned around the composite sleeve. The outer diameter of the composite sleeve is less the inner diameter of the metallic jacket to form a pre-designed gap between the composite sleeve and the metallic jacket The metallic jacket of the hybrid bearing cylinder is adapted to be secured to metallic cylinder end caps by threading, welding, swaging, or other metal attachment methods.

Abstract: An end cap assembly for a fluid cylinder includes a cylindrical casing having a longitudinal axis and an open end, and an end cap closing the open end of the casing. The end cap has a first connecting device for connecting with the casing, and the casing has a second connecting device for connecting with the end cap, whereby the first and second connecting devices interconnect with each other. A backup device is disposed separate from and engaged against the casing or end cap, and prevents deflection of the engaged casing or end cap in a direction transverse to the longitudinal axis.

Abstract: The invention is directed to an apparatus for external fixation and stabilization of a fracture in a bone including a one-piece fixation rod, at least two fixation pins attachable to the bone, and at least two clamp assemblies. Each clamp assembly interconnects at least one fixation pin and the fixation rod, The fixation rod is compressible in an axial direction upon occurrence of axial loads typical to those experienced at the fracture, thereby allowing an axial compression loading to be placed on the bone at the fracture when the apparatus is in use. The fixation rod consists essentially of a non-homogeneous, i.e., composite, material.

Abstract: An end cap assembly for a fluid cylinder is disclosed. The assembly includes a pair of end caps comprising closure units closing the open ends of a cylindrical casing. Each closure unit has an axially extending annular skirt having an outer cylindrical surface telescope within an open end of the casing. The annular skirt has an annular barb radially projecting from its outer cylindrical surface. The inside cylindrical surface of the casing has an annular groove which receives the annular barb to axially retain the skirt within the open end of the casing. A retaining ring is provided within the annular skirt to radially urge the barb into interlocking engagement with the annular groove.

Abstract: A magnetic sealing device for a refrigeration appliance is disclosed that includes first and second pultruded gaskets, one of the gaskets being connected to the cabinet and the other of the gaskets being connected to the door. One of the gaskets has an extruded magnetic seal strip connected to it that interacts with a magnetically attracted material embedded near the surface of the other gasket. The magnetically attracted material is preferably a ferrous mesh screen and is embedded within at least one of the gaskets during the pultrusion process. When the door is closed against the cabinet the first and second gaskets substantially abut to effectuate a seal therebetween. The first and second gaskets are made of material having a low thermal conductivity so that the accumulation of condensate is reduced or eliminated on the sealing gasket and those portions of the surface of the refrigerator adjacent the gasket.
