A high efficiency conductor bar is provided for use in a high flux density environment. The bar is made up of a number of subconductors, each of which consists of strands of small size, insulated copper wire wound into twisted bundles and cables so as to be completely transposed. The subconductors and a tube for coolant fluid are then assembled into a conventionally transposed conductor bar.

An improved wire, rod, stick, and the like to be stored, packaged, transported, and fed into welding apparatus is manufactured so that the ultimate alloying stage is performed when used as filler material, or consumable electrode during welding operation. The wire, rod, stick, according to the invention, which may be with or without fluxing agent, is obtained by selecting constituents in relation to a desired alloy system, mixing the selected constituents, and forming a wire, rod or stick cold working, or by extrusion, the alloy system being obtained at the ultimate welding step with the intermediary wire, rod or stick.

A method and an apparatus for manufacturing elongated, hollow bodies of rectangular cross section by means of hydrostatic extrusion. The method and apparatus utilize a mandrel and billet of novel construction. The mandrel cooperates with a die and has a forming tip comprising a cylindrical portion, a transition portion, and a rectangular portion. The transition portion provides a tapered surface which extends from the cylindrical portion to the rectangular portion. The billet has a leading end which is extruded first and which has a simple geometry comprising two tapered surfaces situated axially adjacent to each other and being of different taper. The billet has an axially extending hole through which the mandrel is inserted. Due to their construction and relative positioning, a hydrostatic seal is provided between the billet's leading end and the die and between the mandrel and an inner wall of the billet which bounds its axially extending hole. The uniform flow between the mandrel and die during extrusion yields a hollow, elongated product of rectangular shape whose corners are free of folds and other metal forming defects. Thus, this method and the apparatus for performing the method enables one step hydrostatic extrusion of hollow, elongated bodies of rectangular cross section with the advantages of providing excellent extrusion lubrication and complete hydrostatic sealing between the die, billet, and mandrel.

Electrical inductive apparatus including a winding disposed in inductive relation with a magnetic core. The winding includes a plurality of conductor turns formed of an electrically conductive material having a predetermined cross sectional configuration. The predetermined cross sectional configuration is selected such that an interlocking structure is formed in which the conductor turns of an axially aligned layer of turns are restrained against relative axial movement.

A die is internal for forming shapes of polygonal cross-section, which has all internal surfaces which are parallel to the die axis of equal length. The die is primarily used in hydrostatic extrusion. It can be made in two parts for ease in cleaning. A billet having a pointed, faceted nose for use with the die is also disclosed.
