Abstract: A wastewater treatment system for deployment in a body of water having a floor and a water surface includes an in-pond clarifier extending across the body of water. The in-pond clarifier defines a clarifying chamber and includes an upper portion and a lower portion. The upper portion is suspended above the wastewater surface. The lower portion is maintained adjacent to the floor of the body of water. As a result, the body of water is divided into distinct treatment zones on opposite sides of the clarifying chamber. The in-pond clarifier further includes a plurality of pumps for removing biological solids which settle within the clarifying chamber. Separate pumps are provided for either returning settled solids to the body of water or for wasting settled solids from the body of water.

Abstract: An electric motor construction and method particularly adapted for integration in rotating final drive members. The motor includes a hollow armature assembly rotatably supported about a permanent magnet stator. The armature assembly includes a winding preferably fabricated by printed circuit techniques in the form of flat conductors clad on a flexible dielectric sheet rolled into a tube and a soft magnetic tube circumferentially surrounding the winding to provide a structural support and a heat sink for the winding and a flux return path for the poles of the permanent magnet stator. In the preferred embodiment, the motor is integrated in the cleaning brush of a vacuum sweeper unit.
