Abstract: A liquid cooled motor enclosure includes a fluid tight space adapted to contain a coolant fluid. A motor is arranged inside the enclosure and is thermally coupled to the inner side of the enclosure. An inlet manifold is located at one axial end of the enclosure, and an outlet manifold is located at the opposite axial end of the enclosure. The cross-sectional areas of the inlet and outlet manifolds are sized and configured to provide for substantially uniform flow of coolant around the entire circumference of the enclosure and/or so that coolant flowing in the space from the inlet manifold toward the outlet manifold is substantially axial. A plurality of projections extend into the space to increase the surface area in contact with the coolant fluid and increase turbulence in the coolant fluid flowing in the space to increase heat transfer from the motor to the inner shell and from the inner shell to the coolant fluid.

Abstract: Yarn package sorting conveyer systems and methods using multiple conveyers based on weights, colors or other characteristics of the packages or yarns. The system may include a first conveyer that serves as a timing belt, a second conveyer that serves as a weighing belt, and a third conveyer that serves as a sorting/exit belt, but fewer or more conveyers and alternative conveyer mechanisms may be used. The conveyers may be controlled by programmable logic controllers (PLCs) with touch screen interfaces or other suitable control mechanisms and systems.

Abstract: Increased resistance to excessive wear rate is provided in certain automobile automatic transmissions by providing a combination thrust-washer/radial-bushing at a certain position on the oil pump stator where the customarily manufactured transmission is provided only with a thrust-washer. The combination thrust-washer/radial-bushing provides bearing surfaces for the direct clutch drum to revolve against in both the lateral and radial directions.
