摘要： “The present invention is for an apparatus and method for a passive pitchable device for wind turbines comprising: a camshaft having cam grooves engraved; a cylindrical shell; an axial compression spring; said blade assembly and said cylindrical shell are fastened together by screws; a plurality of balls that roll along said cam grooves, and convert the axial displacement to rotation or pitch angle; and wherein the passive pitchable device ensures said blades are at the optimum angle of incidence in the stationary position; as the rotor turns, the net force between centrifugal force on said blade and the resistant force from said compression spring causes the device to move axially outward while rotating to adjust the pitch of the rotor blade so that angle of incidence is optimal for the given wind speed; as the wind speed exceeds the design speed and the centrifugal force on the rotor blade continues to increase, the device continues the move axially outward while rotating in the opposite direction as to adjust the pitch of the blade in the opposite direction so that the rotor performance is controlled and severe dynamic loads are avoided”.

摘要： A vacuum pump includes a rotatable cylinder rotatably disposed coaxially around an inner stationary cylinder and in an outer stationary cylinder. The rotatable cylinder has a plurality of recesses defined in inner and outer circumferential surfaces thereof. The outer stationary cylinder has a helical groove defined in an inner circumferential surface thereof. The inner stationary cylinder has a helical groove defined in an outer circumferential thereof. The rotatable cylinder is rotated by a motor to deliver a gas axially along the helical grooves. The recesses are effective to produce turbulent flows in the gas to increase the rate at which the gas is discharged. The recesses have an axial length smaller than the transverse width of helical threads on the outer circumferential surface of the inner stationary cylinder and the inner circumferential surface of the outer stationary cylinder, to minimize any gas leakage across the helical threads.

摘要： A centrifugal pump includes a C-shaped sealing assembly including an annular spring disposed between opposing legs of a base member. The spring biases the legs away from one another into sealing positions. In other embodiments, a vertical pump may be provided so as to include an oil recirculation system which enables an oil-based lubricant to be utilized instead of grease. In still other embodiments, the axial location of a pump shaft may be adjusted by rotating a bearing housing relative to the bearing frame where the two are threadedly connected to one another.
