Abstract: A water flow turbine arrangement for capturing energy from water flows is provided. The arrangement includes: a base member (212); a generally open support structure (210) mounted to the base and upstanding therefrom, the support structure including plural legs (216) joined by a cross brace at or adjacent their upper ends; an electrical generator (230) mounted to the base; and shaft mounted turbine blades (220) mounted for rotation generally within the space occupied by the legs about a turbine axis. The turbine shaft (222) is supported at its upper end by the cross brace and is coupled to the generator at its lower end by a magnetic torque transmitting coupling, allowing complete fluid sealing of the generator's housing.

Abstract: An apparatus and method are provided for simultaneously electropolishing a plurality of metallic stents. A plurality of elongated members on the apparatus are movably engaged with a plate such that movement of the plate relative to the elongated members causes each of the elongated members to rotate on its respective longitudinal axis when immersed in an electrolytic solution. A continuous cathode is located in close proximity to each of the elongated members when they are immersed in the electrolytic solution.
