Abstract: An intelligent current lead device, its design, fabrication, and methods of operation are described in this disclosure. The intelligent current lead device described in this disclosure electrically and thermally connects and disconnects one or more power sources or loads operating at one temperature reservoir with one or more machines or devices operating at either the same or a different temperature reservoir. The intelligent current lead can operate in either an active mode or passive mode. The intelligent current lead device may incorporate the use of multiple types of diagnostic sensors and instrumentation, which can be monitored, interpreted, and analyzed. The program logic of the intelligent current lead may be used to interpret the data obtained from the diagnostic sensors and instrumentation in order to adjust/actuate/switch the current lead so as to optimize its configuration to respond to requirements of an electrical load that changes with time.

Abstract: An exemplary superconducting amalgam magnet or a device enabled by superconducting magnets such as a motor, generator, transformer, FCL, MRI, NMR, accelerator magnet, fusion magnet, etc. fabricated with a conductor comprising of at least one or more low temperature superconductors and at least one or more high temperature superconductors. The high temperature superconductors are used in regions of the amalgam magnet where its current carrying capacity is superior to the low temperature superconductors and the low temperature superconductors are used in the remaining regions.

Abstract: This invention uses a novel approach for the fabrication of low temperature superconducting (LTS) magnesium di-boride (MgB2) wire or cable. This approach employs the use of a “high temperature fiber or tape” as a high performance substrate material. High temperature fiber substrates are low-cost, round, light-weight, non-magnetic, and capable of withstanding, without degradation, the high reaction temperatures necessary to form the superconducting phase of Mg—B.

Abstract: A method of forming magnets using stacked superconducting films-disks of coated conductor is described. The superconducting material may be either from the oxide high temperature superconducting (HTS) class or the metallic/inter-metallic low temperature superconducting (LTS) class. An LTS metallic or inter-metallic compound can include Nb, Va, Ti, Hg, Pb, NbTi, Nb3Sn, Nb3Al, etc. or the more recently discover MgB2. An oxide superconductor refers to the RE-Ba2Cu3Ox compound, wherein RE=Y, Nd, La, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu; the Bi2Sr2CaCu2Ox, the (Bi, Pb)2Sr2CaCu2Ox, Bi2Sr2Ca2Cu3Ox or (Bi, Pb)2Sr2Ca2Cu3Ox compound; the Tl2Ca1.5BaCu2Ox or Tl2Ca2Ba2Cu3Ox compound; or a compound involving substitution such as the Nd1+xBa2?xCu3Ox compounds.

Abstract: Smooth, patterned substrates useful in producing decorative cookware are formed by coating a base with a mixture of fluoropolymer and magnetic flakes and magnetically inducing an image in the polymer coating composition. The baked fluoropolymer release coating contains magnetizable flakes, a portion of the flakes being oriented in the plane of the substrate and a portion of said flakes being magnetically reoriented to form a pattern in the coating which is observed in reflected light, the flakes having a longest dimension which is greater than the thickness of said coating. The patterned substrate is formed by applying magnetic force through the edges of a magnetizable die positioned under a coated base to induce an imaging effect or pattern. The coating composition is then cured resulting in a smooth surface, patterned nonstick finish on the substrate.

Abstract: A self-protected modular high temperature superconducting (HTS) down-lead that is capable of carrying large currents from a room temperature power source to a superconducting device operating at cryogenic temperatures. This down-lead incorporates a safety lead capable of carrying current and absorbing heat to protect the HTS material of the lead in the event of catastrophic failure of the HTS elements. The lead is in continuous contact with the HTS material and provides protection from interrupts and excess current. The down-lead is modular in design, and parts are easily replaced. Further, the down-lead is cooled through conduction in the middle stage, and gas cooled in the upper and lower stages by independent gas sources.

Abstract: Alignment during installation of an octant of a tokamak fusion toroidal magnetic takes place at room temperature or at low operating temperature of the magnet. In order to identify the magnetic center of the magnet, a toroidal magnet octant is electrically powered with equal but opposite flowing current and a spatially known probe is utilized to measure the magnetic field of such a powered octant.
