Abstract: A permanent magnet motor, generator or the like that uses ceramic magnets in the rotor to concentrate the magnetic flux in the airgap. Magnet poles are formed by pole plates with tabs forming north and south poles with magnetic separators therebetween. Magnet sections are stacked axially. Connection to the shaft is made by means of a collet or other attachment method.

Abstract: The subject invention pertains to a method of spark processing silicon and resulting materials. The subject invention also relates to electroluminescent devices incorporating the materials produced by the subject method. The subject method for spark-processing can enhance the EL output, as compared with conventional spark-processed (sp) silicon. The enhancement of EL output can be due, at least in part, to increasing the light emitting area. The subject method can smooth the sp surface, so as to allow more complete coverage of the sp area with a continuous, semitransparent, conducting film. The smoothening of the sp surface can be accomplished by, for example, introducing into the spark plasma a volatile liquid, such as methanol, ethanol, acetone, in which particles can be suspended and/or in which a heavy ion salt is dissolved. The particles preferably float in the volatile liquid, rather than settle quickly. In a specific embodiment, silicon particles in the range of about 0.

Abstract: A screw compactor comprising a housing (4) having an opening for the insertion of wet waste to be compacted and defining a compaction volume (14); a screw (8) rotatably mounted in the housing; a guideway for transporting compacted waste from the compaction volume; a motor (10) for rotating the screw; and a duct (20) to pass air heated by the motor (10) to the guideway to heat the compacted waste. The heating of the compacted waste reduced the liquid content in the compacted waste by enhancing evaporation.
