Abstract: A method of fabricating a rugged, flexible, superconducting wire comprising: mixing a superconducting material, such as YBa.sub.2 Cu.sub.3 O.sub.x, with a metallic powder to form a metal/superconductor mixture; and loading a metal shell or tube with the metal/superconductor mixture to form a superconducting wire. The superconducting wire may also be cold drawn and annealed to form a very dense wire. The metallic powder is either copper, copper alloy, aluminum or other face centered cubic element. Additionally, a superconducting wire may be formed by encapsulating a superconducting filament within a metal shell.

Abstract: A process and apparatus for fabricating an optical fiber cable core assembly having at least one optical fiber encapsulated with an ultra-small diameter metallic tube are described. The optical fiber cable core assembly is formed by passing a metal or metal alloy strip through at least one die to form the ultra-small diameter tube, inserting at least one optical fiber or fibers into the tube during the tube formation operation and passing the assembly through a sealing station to seal the tube and provide a hermetic core assembly. To reduce the likelihood of breaking the tube and damaging the optical fiber or fibers therein, the deformation energy for forming the strip into the tube is provided by wrapping the assembly about a tensioning device positioned between the tube forming station and the tube sealing station.

The device has a central member adapted to receive a plurality of coils of strip material and free to rotate about its longitudinal axis and a plurality of retractable spacing elements for separating adjacent coils of material without interfering with the material feed operation. To insure a supply of material sufficient to enable operation of the equipment for long periods of time, the coils stacked on the central member are interconnected.

Abstract: A hollow tubular structure having edges held in close proximity by residual compressive forces in the material forming the tubular structure is formed by first drawing a metal or metal alloy strip through a first die and forming an open tube section and then drawing the open tube section through a second die.

Abstract: A process and apparatus for producing increased reductions in strip material, particularly soft metal strip materials, are disclosed. The process and apparatus utilize a rolling mill having at least two offset work rolls driven at a peripheral speed ratio less than a desired gage reduction ratio but greater than zero and a mechanism for applying forward tension to the strip material. The desired gage reduction may be obtained using reduced separating force magnitudes and minimized tension force magnitudes. The rolling mill utilizes relatively small diameter work rolls without having to provide additional support structures other than the back-up rolls and frame roll supports to prevent roll bending in the rolling direction. Roll flattening is substantially eliminated resulting in improved gage control and strip flatness.

The optical fiber cable has a cable core including a metal containment tube and at least one optical fiber within the tube. The containment tube preferably is formed by drawing a strip of metal through at least one forming die.

In a first embodiment, the tube is sealed using a wave soldering approach wherein a flow of moving molten solder is used to substantially fill a seam in the tube.
