Systems and methods are described herein for manufacturing a pressure vessel component. The pressure vessel component may be made from a metal that is cast to produce a gross pressure vessel component. Casting the metal may comprise sintering the metal followed by a hot isostatic press (HIP) process. In other embodiments, casting the metal may comprise pouring molten metal into a mold. Portions of the gross pressure vessel component may have an increased thickness located at predetermined positions on the gross pressure vessel component. These portions may include bosses or other designed features intended for the finalized pressure vessel component. The gross pressure vessel may be indexed to select the portions, and these selected portions may then be machined to produce the final pressure vessel component.

Systems and methods for adding buoyancy to an object are described herein. A buoyant material may be enclosed inside a flexible container, heated, and inserted into a free flooded cavity inside the object. The flexible container may then be formed to the shape of the cavity. After the flexible container is formed to the shape of the cavity, the flexible container may be cooled. The flexible container may hold a pre-determined amount of the syntactic material that provides a fixed amount of buoyancy. According to another aspect, systems and methods for packing a vehicle are described herein. In some embodiments, a buoyant material may be molded into the shape of a hull of a vehicle, and a plurality of cutouts may be extracted from the buoyant materials which are specifically designed to incorporate one or more instruments.

According to the method of stripping a portion of a wire of the invention, the insulated wire including the wire core are first flattened before the insulation is stripped away. The flattening eases the stripping as the insulation is partially cracked and dissociated of the wire core, and the stripping is more efficiently applied on a flat surface. A wire stripping machine and a transponder antenna with stripped portions are also claim as being part of the invention.

The inventive device (10) for carrying out the inventive method which consists in producing by moulding a circular-shaped mechanical part in the form of a bearing ring made of a metal alloy comprises a rotatable hollow mould (11) for receiving in a crucible (13) a predetermined quantity of the metal alloy which is defined by one or several segments (21) of a metal alloy rod (20), an inductive heating device (23) for heating said metal alloy to a melting point T1 and means for producing the blank (26) of the part by centrifuging. The cooling of the produced blank to a temperature T2 corresponding to malleability thereof is carried out by cooling means in the hollow mould. When said malleability is obtained and the blank is extracted from the mould, the internal profile of the mechanical part is obtained by processing means, the temperature thereof is adjusted by a device in such a way that it is possible to attain a quenching temperature T3 and to carry out a quenching process.

The disclosed invention comprises a novel golf club head and method of manufacturing the golf club head. The golf club head comprises a multilayer construction having a soft nickel alloy core and a hard chrome coating. The process used to produce the golf club heads involves an investment casting process in which the soft nickel alloy core is cast and the hard chrome coating is plated to the core. This multilayer design produces a golf club iron that is durable and consistent from iron to iron with feel characteristics which are generally equal to or better than traditional clubs formed from forged mild carbon steel.
