Abstract: The cooling system includes a plurality of generally radially extending passages within the airfoil for convectively cooling the airfoil. A predetermined number of the passages exit through the airfoil tip. One or more of the remaining passages exit into a plenum adjacent the trailing edge and airfoil tip region of the airfoil and flow radially inwardly along one or more passageways adjacent the trailing edge region. The passageways exit in openings along the pressure side of the airfoil. In this manner, the trailing edge region is convectively cooled as well as film cooled by the film of air exiting the holes.

Abstract: A self-aligning coupling for mating a pair of corresponding flanged fittings, generally for pipe couplings. The self-aligning coupling includes a first arm, a second arm, and a rotational assist mechanism adapted to mechanically synchronize the closing of the first and second arms relative to the flanged fittings to be connected. The rotational assist mechanism is further adapted to provide motion between the first arm and the second arm to receive and secure the flanged fittings in axial alignment.
