摘要： A superconductive lead assembly for a superconductive device (e.g., magnet) cooled by a cryocooler coldhead having first and second stages. A first ceramic superconductive lead has a first end flexibly, dielectrically, and thermally connected to the first stage and a second end flexibly, dielectrically, and thermally connected to the second stage. A first glass-reinforced-epoxy lead overwrap is in general surrounding contact with and attached to the first superconductive lead. The first lead overwrap has a coefficient of thermal expansion generally equal to that of the first superconductive lead. The lead overwrap protects the lead from moisture damage and from breakage during handling. For added protection against shock and vibration while in the device, the lead assembly is surrounded by a (e.g., polystyrene foam) jacket surrounded by a helically-wound metallic wire surrounded by a glass-reinforced-epoxy jacket overwrap surrounded by a rigid support tube.

摘要： A superconductive device (e.g., magnet) having a superconductive lead assembly and cooled by a cryocooler coldhead having first and second stages. A first ceramic superconductive lead has a first end thermally connected to the first stage and a second end thermally connected to the second stage. A jacket of open cell material (e.g., polystyrene foam) is in surrounding compressive contact with the first ceramic superconductive lead, and a rigid, nonporous support tube surrounds the jacket. This protects the first ceramic superconductive lead against shock and vibration while in the device. The rigid support tube has a first end and a second end, with the second end thermally connected to the second stage.

摘要： 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.

摘要： 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.

摘要： An MR magnet assembly includes a cylindrical vessel for housing a superconducting magnet and having a vacuum between its inner and outer walls. The vessel defines a magnet bore for receiving a patient to be imaged. A gradient coil assembly is mounted in the bore adjacent the inner wall of the magnet assembly. To reduce gradient coil noise, the inner wall is constructed of a non-conductive material which does not support eddy currents.
