Abstract: A centrifugal pump having a turbine impeller having a plurality of curved vanes. The vanes curve from the inlet end to the outlet end in the direction of pumping rotation of the impeller, such that the leading wall of each vane re-directs a portion of the radial velocity of the fluid flowing through the passage to increase the total tangential velocity provided by the impeller. Each curved passage has cooperating inlet and outlet areas and a smooth curved shape to ensure that the radial velocity of the liquid does not decrease dramatically while flowing through the passage, while ensuring that any solid particulates and contaminants entering the impeller will pass therethrough.

Abstract: A combination euchre score and trump indicating device. The system includes a pair of scoring dials that are mounted to the interior face of a pair of end caps. The end caps removably mate with a body. The body is generally cube-shaped having four flat outer surfaces. Each outer surface prominently bears one of the four trump suits. When the end caps are coupled to the body, the interior faces and scoring dials are hidden by the body, protecting the scoring dials from damage and fully enclosing an internal storage compartment.
