The embodiment of the invention illustrated in FIG. 4 performs in the same manner as the embodiment of FIG. 1 but has structure charges to permit packaging in a different shape. This is accomplished by organizing the components along two major axes rather than on a single major axis. In ef...
kinetic energy to be transferred from the wind into usable mechanical energy, and subsequently, electrical energy. For instance, the hub6may be rotatably coupled to an electric generator10(FIG.2) positioned within the nacelle4or forming part of the nacelle to permit electrical energy to be ...
. For spalls having a depth of over 20 mils and approaching 50 mils, the composition of the present invention can be provided using a lower weight percentage of solvent, yielding putty-like properties to allow application of the composition using a blade or putty knife and to permit working ...
upstanding annular wall forming a cavity in an upper surface of the guiding sleeve. At least one Belleville spring is mounted in the cavity to permit deflection of the assembly during the operational range of the actuator. A thrust plate is mounted on the Belleville spring and attached to the...
