    Abstract: The blade structure of a wind turbine which has enough strength for sporadic large load and increased durability. The blade can be formed into a thinner blade profile, with which blade performance is improved, increased efficiency of the wind turbine is attainable, and the noise induced by Karman vortex street is reduced. The blade is made of metal and formed into a one-piece blade or a split-type blade consisting of a main blade body made of metal and a rear end member made of metal other than that of the main blade body, the rear end member being fixed to the rear end of the main blade body, dentation being formed in the trailing edge part of the blade along the length thereof, the dentation being shaped in a serration of triangular teeth, of trapezoidal teeth, or of sawteeth, the ratio(h/&dgr;) of the tooth height h to the thickness &dgr; of the boundary layer developed on the surface of the blade is: h/&dgr;=1.0˜10.0, and the ratio (h/p) of the tooth height h to the pitch p is: h/p=0.5˜5.0.

    Abstract: An oscillating centrifugal pump is disclosed which has a housing, an impeller and a magnetic drive. The housing has a longitudinal axis, having a front end and a rear end that are spaced apart on the longitudinal axis. The housing includes a pumping chamber within and at the front end of the housing. The pumping chamber is created by a continuous transverse front wall that closes the pumping chamber at the front end of the housing, a transverse rear wall axially-spaced from said transverse front wall and has a central opening, and a longitudinal closed side wall which is between the front and rear transverse walls. The housing is closed except for an inlet in the housing that is outside of and is axially spaced from the pumping chamber. An outlet is provided in the longitudinal side wall of the pumping chamber, and the housing is free of mechanical bearings, flexing or external seals or apertures that lead to the exterior of the housing except for said inlet and outlet. The impeller is located in the pumping chamber and has an axial inlet and a radial outlet and a flow passage between the impeller inlet and outlet. The impeller is mounted on an elastic support, which provides limited freedom of angular oscillation for the impeller about the longitudinal axis of the housing.

    Abstract: Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.
