Abstract: A coupling apparatus for trucking straps used on flatbed trailer loads intended to hold stacked loads in a more secure manner while eliminating their tendency to shift during transit is herein disclosed. The apparatus provides a connecting link which takes the form of a flattened figure “8” with the approximate dimension of four-and-a-half (4½) inches wide and two-and-a-half (2½) inches tall. The link is used to hold one end of a conventional trucking strap, which is then looped around a load and then back through the other side of the link. The free end is then secured to a stationary object such as a rub bar on the edge of the flatbed trailer using a ratcheting buckle. Thus, the loop around the load is self tightening and automatically tightens in the event of a shifting load as is commonly the case with tubular loads such as PVC pipe, regular pipe, lumber and the like. The apparatus would be used on alternating sides of the load to provide a balanced bi-directional restraint.

Abstract: The present invention concerns a wind turbine having a plurality of vertically extending airfoils forming a rotating carousel rotating about a central axis thereof. The airfoils pivot about their leading edges to adjust the pitch angle thereof to maximize energy harvest when the airfoils are rotating both in an upwind direction and in a down wind direction. This pivoting movement results from trailing edges of the airfoils being pivotally secured to rigid spokes or cables of a trailing edge hub. An adjustment mechanism is pivotally mounted between a carousel hub and the trailing edge hub and is used to control the separation between a central axis of the trailing edge hub and the axis of rotation of the carousel as they co-rotate. As the carousel rotates, the offset distance between the two axes determines the maximum achievable pitch angle of each airfoil.
