Abstract: A wrapping machine for use in constructing layered vessels having at least one layer formed of adjoining vessel sections wherein the wrapping machine has an interlooped band mechanism for positioning adjoining vessel sections adjacent one another and a tightening mechanism in operative engagement with the band mechanism for tightening the band mechanism about adjoining vessel sections with the interlooped band mechanism providing concentric loading of the layered vessel when the tightening mechanism draws the vessel sections together.

Abstract: An oil well pipe incorporates a corrosion-resistant, metallic liner which is intimately metallurgically bonded to the pipe bore.

Abstract: A clad wire having a cast metal core with a formed sheath intimately bonded to the core with the interface portions thereof being effectively free of intermetallic compounds. The clad product may be formed by the steps of forming a strip of first metal into a closed tube, introducing a fused second metal into the tube from a position upstream of the tube and causing the fused second metal to quickly solidify within the tube while effectively causing a separation of the tube and core interface portions for a sufficient short period of time to permit the core temperature to drop below the temperature at which intermetallic compounds of the core and sheath tube material readily form.

Abstract: Manufacturing process for a solid or hollow shaft consisting of aluminum or itanium with beryllium reinforcing therein. Beryllium rods are either clad with aluminum or titanium or, in the alternative, holes are drilled in an aluminum or titanium block which beryllium material is thereafter inserted into the holes. The preform with a hard steel central mandrel around which the beryllium rods are positioned is placed within a steel can and heated to a predetermined temperature. Pressure is then uniformly applied to outer circumference of the can to ensure uniform deformation of the beryllium reinforcement. The uniform exterior pressure on the outer surfaces of the beryllium rods and the interior pressure on these rods caused by the hard steel mandrel against the under surfaces of the rods as a result of a reduction process causes the beryllium rods to assume an arcuate ribbon configuration. For hollow shafting, the mandrel at the center of the preform may later be removed.

Abstract: In the manufacture of compound billets composed of two or more different metals for use in hydrostatic extrusion, care must be exercised to see whether or not products possessing a predetermined compound status are produced from the compound billets by means of the hydrostatic extrusion process.
