Abstract: Apparatus for winding an electrical conductor, having a compressible electrical insulation, on a coil form to make a conductive coil. A rotating device rotates the coil form. A guiding device guides the conductor, near the coil form, longitudinally toward the second end of the coil form so that successive turns of the conductor are generally abutting and are laid down in a first layer. A locating and longitudinally-translating device moves a rotatable wheel so that its rim contacts, and is rotated by, the rotating coil form and so that a side of the wheel applies a first longitudinally-compressive force to a portion of a presently-wound turn of the first layer of the conductor in a direction toward the first end of the coil form.

Abstract: A superconducting field winding assemblage for an electrical machine, such as a rotary generator or a linear motor. The field winding assemblage includes at least two pole assemblies. Each pole assembly has a direction of motion, a solid core, a superconductive coil assembly generally surrounding the solid core, and a first cooling conduit. The superconductive coil assembly has a generally longitudinally extending axis positioned generally perpendicular to the direction of motion and has an epoxy-impregnated, generally racetrack-shaped superconductive coil having a minor axis positioned generally parallel to the direction of motion. The first cooling tube contains a gaseous cryogen (such as gaseous helium) and is positioned to be in thermal contact with the superconductive coil.

Abstract: A superconductive magnet has a superconductive coil surrounded by a thermal shield surrounded by a vacuum enclosure. The thermal shield has one and preferably several flexible layers of thermally conductive material. A first flexible blanket of multi-layer thermal insulation surrounds the thermal shield within the vacuum enclosure, and a second such flexible blanket surrounds the superconductive coil within the thermal shield. A cryocooler coldhead has a first stage in thermal contact with each of the flexible layers of the thermal shield. At least most of the weight of the thermal shield is supported by the flexible blankets.
