Abstract: A magnetic confinement system includes a magnetic mirror device that includes a chamber to hold a target plasma and a coil arrangement to generate a magnetic field configuration in the chamber to confine the target plasma in cylindrically-symmetric form in the chamber, the magnetic field configuration having open ends. The magnetic confinement system further includes plasma guns to generate plasma pistons and project the plasma pistons at the open ends of the magnetic field configuration. In operation, the plasma pistons converge towards each other to close the open ends of the magnetic field configuration and to compress and heat the target plasma.

Abstract: Magnet wire with corona resistant enamel insulation may include a conductor and a multi-layer insulation system formed around the conductor. The insulation system may include a basecoat formed from a first polymeric enamel insulation. A midcoat formed from a second polymeric enamel insulation may be formed around the basecoat, and the second polymeric enamel insulation may include a filler dispersed in a base polyimide material. The filler may include between 20 percent and 80 percent by weight of silica dioxide and between 20 and 80 percent by weight of titanium dioxide. Additionally, the insulation system may include a topcoat formed from third polymeric enamel insulation formed around the midcoat.

Abstract: Magnet wire with flexible corona resistant enamel insulation may include a conductor and a multi-layer insulation system formed around the conductor. The insulation system may include a basecoat formed from first polymeric enamel insulation, a midcoat formed from second polymeric enamel insulation, and a topcoat formed from third polymeric enamel insulation. The midcoat may include a filler containing silica dioxide and chromium oxide dispersed in a base polyamideimide material. Additionally, the magnet wire may exhibit few or no cracks in the topcoat when the wire is bent 180 degrees around a 4 mm mandrel.

Abstract: A magnet wire insulation designed to withstand voltage wave shapes present in inverter driven motors for a sustained period of time is disclosed. A large surface area inorganic oxide, e.g., fumed silica, may be added into the magnet wire insulation for providing improved resistance to insulation degradation. Alternatively, a mixture of the large surface area inorganic oxide with a low resistivity oxide, e.g., chromium oxide, provides a greater improvement in resistance to insulation degradation. The present invention is particularly useful for extending the life of windings in a motor that is subjected to high voltage, steep wave shapes such as those found in inverter driven motors.

Abstract: Traditional alternators, that is those non-inductor alternators employed in machines such as automobiles, provide either moving conductors which cut through a stationary magnetic field, or a moving magnetic field which passes over stationary conductors. In conventional inductor alternators, neither the field nor armature rotate. An electromotive force is induced in the output windings by periodic changes in the local reluctance of the magnetic circuit carrying the magnetic flux. The reluctance is governed by the shape of the rotor relative to the stator. By the elimination of the stator housing and of the rotor encompassing stator, this invention provides for the use, as inductor alternator rotors, of components which previously could not function as rotors.

Abstract: An ultra-high solids content, organic solvent solution of polyester magnet wire enamel is described. The enamel is a tris (2-hydroxy-ethyl) isocyanurate polyester having a ratio of hydroxyl to carboxyl groups of 1.65 to 2.0:1 and a hydroxyl number of 216 to 316. Such enamels are produced with solids contents of greater than 70% by weight and viscosity less than 3,000 cps at 160.degree. C. The method of making such enamel by reacting a glycol, tris (2-hydroxy-ethyl) isocyanurate, and an aromatic diacid or diester, reacting this polymer with modifying phenolic and polyisocyanate and adding an aromatic titanate catalyst is also described.

Abstract: A high solids content, relatively low viscosity, organic solvent solution of polyester magnet wire enamel is described. The enamel is a tris (hydroxy-ethylisocyanurate) polyester having a ratio of hydroxyl to carboxyl groups of 1.65 to 2.0:1 and a hydroxyl number of 216 to 316. Such enamels are produced with solids contents of about 50 to about 70% by weight and viscosity less 1,500 cps at 200.degree. F. The method of making such enamel by reacting a glycol, tris (hydroxy-ethylisocyanurate), and an aromatic diacid or diester in the presence of a titanate catalyst is also described.

Abstract: A method of improving the physical and electrical properties of polymer insulation coated electrical conductors is described. A non-ionic surfactant added to an organic solvent solution of insulation polymer followed by coating the solution on the wire, drying and curing, has been found to produce a coated magnet wire with improved concentricity and smoothness, therefore resulting in improvement in other wire properties as well.
