Abstract: The present invention is directed to an improved vertical-axis wind turbine rotor that provides a more constant shaft power output than similar turbine rotors of the prior art. In a preferred embodiment, it provides four tiers of blade sets, with each set disposed at a different elevation than each other set. Each blade set may be offset at an angle from adjacent blade sets. A partition plate may be disposed between adjacent blade sets. The partitions provide structural stability and enhanced rotor performance characteristics.

Abstract: A novel cover (10) for one end of the casing within which a vehicular transmission is housed and a unique method for making the cover. The cover (10) has a metallic body portion (12) within which a unitary manifold (40) has been cast in situ. The manifold (40) incorporates a plurality of conduits having artight mechanically crimped ends (A-E) which have been preformed and conjoined into the unitary manifold (40) that is precisely disposed within a mold. Molten metal is admitted into the mold to encapsulate the manifold (40) within the metallic body portion (12) of the cover (10). After the cover (10) has been cast, with the manifold (40) encapsulated therein, the cover (10) is removed from the mold, and only a relatively modest amount of machining operations are required to complete the cover (10).
