When joining together oxide superconductors by use of a solder composed of an oxide superconducting material, a finally solidified portion of the solder is positioned in a region where a transmission path of electric current flowing between oxide superconductor base materials as joined together is not obstructed by, for example, disposing the solder on a face of the oxide superconductor base materials, other than butting surfaces of the oxide superconductor base materials, so as to straddle both the base materials like bridge-building. Current flow is also not obstructed by, for example, shaping junction faces of the oxide superconductor base materials such that at least portions of the butting surfaces thereof are in the shape of sloped open faces, parting from each other.

Abstract: A method of designing and manufacturing a magnetic separation apparatus. Past separators generally had poor power efficiency, poor throughput performance, and/or were bulky. Designing the magnetic separator of the present invention involves selecting a diameter and height for a separation container and superconducting coil by optimizing at least one parameter from a group of parameters. The magnetic separation apparatus includes a superconducting electromagnet and separation container having a diameter of about 60 inches, a height of about 40 inches, an inlet port, an outlet port, and removable matrix modules. The electromagnet generates a magnetic field strength within the separation container of greater than 3 Tesla. The optimized separation container volume, the high magnetic field strength, and the matrix modules allow the magnetic separation apparatus to have greatly increased slurry processing capacity.

Abstract: Structure and a method for producing very dense bodies of material from particulate materials. A particulate material is placed within an electrically conductive container. A solenoid or coil encompasses the electrically conductive container, and a large magnitude of electrical current is caused to flow through the solenoid or coil. As the electrical current flows through the solenoid or coil, large magnitudes of magnetic pressures are created upon the electrically conductive container, and the electrically conductive container is compressed, and the transverse dimension thereof is reduced. Thus, the particulate material within the electrically conductive container is very firmly compacted, and a rigid body of material is provided. Any one of numerous types of particulate material may be employed. For example, a body of electrical superconductive material of any desired size and shape can be produced by this method by the use of superconducting particulate material.

Abstract: A superconducting electrical conductor comprises a porous substrate of bonded fibers which are coated by ceramic oxide superconducting material of the perovskite type so that its critical temperature of superconductivity is at or above the boiling point of liquid nitrogen. To form electrical cable, the conductor is encased within an inner tube. An outer tube surrounds the inner tube and defines an evacuated annular space therewith. This provides a thermal barrier between substrate, which will be bathed by liquid nitrogen, and the ambient. Electrical and heat insulation surrounds the outer tube.Joint connectors in the form of multiple rigid rods, each coated by superconducting material and held in a perforated frame, are used to connect facing ends of the substrate to form an electrical connection from one length of conductor to the next.
