Abstract: An electromagnetic apparatus produces an asymmetrical magnetic field. The electromagnetic apparatus includes a stator and a rotor rotatable relative to the stator. The stator includes electrically conductive wiring subject to non-zero voltage input. The rotor includes an electrically conductive rotor shaft having a shaft voltage induced therein. The electromagnetic apparatus further includes a bearing rotatably supporting the rotor shaft and an electrically insulative arcing shield disposed in overlying engagement with the bearing. The arcing shield comprises a fibrous composite material. The fibrous composite material includes a plurality of fibers and a resin.

Abstract: A computer-implemented method for interparty component supply chain control that includes accessing, at a computing system operated on behalf of a downstream production entity, a database containing supplied part substance data relating a substance contained in a component part to a governmental restriction. The method includes generating, at the computing system of the downstream production entity, an electronic message describing performance of an action by a further downstream entity to be taken on or relative to the component part based on the governmental restriction, and transmitting the electronic message to a computing system operated on behalf of the further downstream entity.

Abstract: A rotating element for a dynamo-electric machine such as an electric induction motor. The rotating element includes a plurality of axially stacked laminations cooperatively defining a plurality of arcuately spaced bar slots. The rotating element also includes a plurality of bars, with each bar extending through one of the bar slots. Each of the bars comprises copper-impregnated polymer.
