Abstract: A removal assembly and method for removing a submaster from a master is described. A curved tooling surface is arranged within a housing of the assembly. A first array of vacuum cups is attached to the housing adjacent a first end of the curved tooling surface, where the first array of vacuum cups are configured to provide a vacuum grip on a first portion of the submaster. A second array of vacuum cups is attached to the housing adjacent a second end of the curved tooling surface, where the second end opposes the first end, the second array of vacuum cups is configured to provide a vacuum grip on a second portion of the submaster. A rotation mechanism is configured to rotationally support the master as the master is rolled along the curved tooling surface to remove the submaster.

Abstract: A propeller type wind motor arrangement having a blade mounting hub, a plurality of air foil blades, and blade receiving means for mounting the blades to the hub for pivotal movement about a longitudinal axis of the blades is provided with a governor for retaining the blades at a first high torque, relatively low tip speed ratio forming angle during motor start-up and at rotational speeds below a minimum normal operational speed, and for abruptly shifting said blades to a second high efficiency, relatively high tip speed ratio forming angle when said operational value is reached.
