Abstract: An impeller for a pump for conveying wastewater is proposed, includes a shroud to be rotated about an axis of rotation defining an axial direction, and a blade to convey the wastewater. The blade includes a leading edge, a trailing edge, a pressure side, a suction side and an upper rim. The blade extends from the shroud in the axial direction to the upper rim and extends in a circumferential direction from the leading edge to the trailing edge. The suction side is the radially inner surface of the blade and the pressure side is the radially outer surface of the blade. The blade includes a closed passage extending inside the blade. The passage has an inlet at the pressure side and an outlet at the suction side of the blade.

Abstract: Footwear with an improved sole, and an improved sole and a method for manufacturing the same are provided. The improved sole includes at least one pod secured in situ to a molded outsole. Each pod includes a ground-engaging end and an upper end having an outwardly extending flange proximate thereto. In the method for manufacture of the sole, the outsole is secured to the pods in situ. The outsole and pods are formed from different materials and are secured in situ during formation of the outsole, with each pod placed in a mold cavity section and the flange being encapsulated by the moldable outsole material.

Abstract: The present invention provides an apparatus for display and support of one or more plates. The apparatus comprises two sets of support members which are arranged in two tiers to hold three plates. Each plate is supported at spaced points about its outer periphery. The upper support is connected to two pivotable arms to support one plate about its outer periphery to prevent horizontal and vertical movement of said plate. The lower support has two pivotable arms to support two plates about their outer peripheries to prevent horizontal and vertical movement of the two plates. The lower support also has rear supports which prevent a plate's backward movement. The upper and lower supports are interconnected by a bracket which is securable to a wall. A portion of the upper support engages the upper, outer periphery of the two plates in the lower tier of plates to prevent forward movement.
