    Abstract: Apparatus and method for superplastic forming. The workpiece is held between a pair of dies that are electrically and thermally nonconductive, and is heated inductively by a coil embedded within the dies. The dies are formed of a material that is substantially transparent to inductive heating. A plurality of electrical conductors are embedded within the die. The electrical conductors are interconnected into one or more electrically conductive coils that surround the workpiece. The electrical conductors are used to produce a time varying magnetic field that is used to heat the workpiece. In one embodiment, the workpiece is a composite material that is susceptible to inductive heating. The composite material includes an electrically conductive material. The time varying magnetic field heats the electrical conductive material, thereby heating the workpiece. The die also includes a forming surface having a shape corresponding to a desired shape of the workpiece. A pressure differential is created between the first and second sides of the workpiece to deform the workpiece to the shape of the forming surface.

    Abstract: The invention is related to a continuous coating apparatus for applying molten metal on a metal sheet or tape. The apparatus has an annular cylinder having an open lower section extending to a substantially closed upper section. An axle is mounted in the lower section normal to the cylinder axis, and a spool is mounted on the axle. A pair of tubes are mounted parallel to the cylinder axis inside the cylinder on oppositely facing surfaces so that a tape extending around the spool towards the upper section extends through the tubes.
