A pressure vessel or pressurizable canister has a hollow, thin-walled, cylindrical metal shell or tube. Two end caps are hermetically sealed to the respective distal ends of the metal shell by the process of magnetic pulse welding that requires no external heat. The two end caps are made of a metallic alloy such as aluminum. The end caps are each cylindrically shaped and have at least one circumferential recess to accommodate the metal of the shell tube as it deforms about the end caps and forms an intermolecular bond. The canister can hold a pressure of at least 1,800 psi.

A method and apparatus for fabricating uniform splices for stranded cables. A joint for a stranded cable can be formed by inserting the ends of two cables into an electrically conductive splice band which, in turn, is inserted into a coil or inductor. The splice is fabricated by a process known as magnetic pulse forming, or magnetic pulse welding wherein a very large electrical current of short duration is directed through the coil or inductor from a charged capacitor bank. The resulting magnetic field in the coil or inductor induces a magnetic field on the splice band, compressing the splice band uniformly around the circumference of the two cable ends being spliced. In the case of magnetic pulse welding, the splice not only uniformly compresses the stranded cables, but a weld is also created between the inner diameter of the sleeve and the adjacent stranded cables.

A method of forming a tubular frame, e.g., a bicycle frame, from two substantially symmetrical frame-halves utilizes a plurality of interconnected half-tubular elements. Each half-tubular element has an exterior surface, an interior surface, and longitudinal edges that extend between the exterior and interior surfaces in the direction of the longitudinal axis of the half-tubular element. The surfaces of the longitudinal edges of the half-tubular elements are shaped such that corresponding edges of corresponding half-tubular elements in the left and right half-frames may easily be interengaged, and adjusted along the respective longitudinal axes of the half-tubular elements that are being joined. Preferably, the longitudinal free edges are stepped in the radial direction such that each level is substantially planar and smooth along the respective longitudinal axis of the half-tubular element. The longitudinal edge of one of the half-tubular elements may include parallel steps extending in opposite directions to thereby form a groove into which a step of the corresponding longitudinal edge of the corresponding half-tubular element in the other half-frame may be inserted. The latter joint type provides additional reinforcement of the connection of the half-frames. Further reinforcement in the stay area of the bicycle frame may be provided, either in the form of a reinforcement arch positioned within the tubular legs of the stays, or in the form of a one-piece, unitary inner stay element positioned between the outer stay elements that are part of the frame-halves.

A pressure vessel, or pressurizable canister is described herein. The canister has a hollow, thin-walled, cylindrical, metal shell. The preferred metal is aluminum, because light weight is a consideration for the vessel. Two end caps are mechanically sealed to the respective distal ends of the metal shell tube by the process of electromagnetic pulse forming. The two end caps are made of a high strength, ductile thermoplastic. The preferred plastic is DELRIN.RTM., which is fabricated from an acetal resin. The plastic end caps are injection molded, and can include reinforcing threads. The end caps are each cylindrically shaped, and have at least one circumferential recess to accommodate the metal of the shell tube as it deforms about the end caps. The tube shrinks into the recess of the end caps, and forms a mechanical seal therewith. An O-ring seal is disposed within at least one circumferential recess of each end cap, to further the ability of the mechanical seal to hold a pressure of at least approximately 300 psi.

A new method of fabricating the joint between a golf club head and the golf club shaft, and the article fabricated therefrom, is described herein. The golf club head in which the shaft is inserted has a bore hole having a recessed contoured aperture. The hollow, metal, or electrically conductive golf club shaft is placed into the bore hole of the club head, and an electric coil is placed inside the shaft. The electric coil is electrically pulsed, causing the shaft to expand outwardly to fit the contour of the aperture. The electro-formed, mechanically-bonded shaft is now permanently and integrally anchored to the golf club head. The club head aperture is additionally fitted with a plurality of vertically-disposed grooves along the vertical shaft axis. These vertical grooves capture the shaft as it expands outwardly to the internal surface during electromagnetic forming. The electromagnetically-formed shaft expands into these grooves and is prevented from rotationally or angularly slipping about the club head. In another embodiment, a non-conductive shaft can be used. The non-conductive shaft contains a conductive sleeve that is electrically formed thereon, and is bonded to the club head by a second electro-forming process.

Golf club fabrication process and article

A new method is disclosed of fabricating the joint between a golf club post and a drive shaft, as is the article fabricated therefrom. The golf club post to which the shaft attaches includes a circumferential recessed contour. The hollow, metal, electrically conductive golf club shaft is placed over the post, and an electric coil is placed around the shaft and post juncture. The electric coil is electrically pulsed, causing the shaft to shrink fit to the contour of the post. The electro-formed, mechanically bonded shaft is now permanently and integrally anchored to the golf club post. In a second embodiment, a non-conductive shaft of carbon fiber, for example, is electromagnetically bonded to the post, using a metallic ring, which is electromagnetically formed around the non-metallic shaft and post. In a third embodiment, the club head post is additionally fitted with at least one vertically disposed groove along the vertical axis of the post. These vertical grooves capture the shaft as it shrinks to the post surface during electromagnetic forming. The electromagnetically formed shaft shrinks into these grooves, and is prevented from rotationally or angularly slipping about the post.

A titanium-nitride coated carbide cutting tool is formed with complex angularly intersecting surfaces which form cutting edges having a generally trapezoidal configuration. The tool creates fine thread-like grooves in a circumferential wall of a tube which may be employed as a heat pipe. The generally trapezoidal resulting groove increases groove surface area that in turn increases working fluid wicking action.
