Abstract: A method of forming a blade comprising the steps of forging a part comprising a suction side, a pressure side, and a dividing portion of material greater than a portion of material to be sacrificed between the suction side and the pressure side, splitting the part through the dividing portion of material to form a suction side inner surface and a pressure side inner surface, and joining the suction side inner surface and the pressure side inner surface to form the blade.

Abstract: The invention relates to a power door opener, such as the type of opener used for opening overhead garage doors includes a worm gear rod having a major thread and a carrier member coupled to the door and releasably engageable with the major thread for moving the door between open and closed positions as the rod rotates. A second thread whose pitch is smaller than the major thread is formed on the rod and on a portion thereof located between a pair of spaced apart limit switches. A control member threadably engages the second thread for movement between the limit switches as the rod rotates for terminating motor operation as the door moves into its open and closed positions. The carrier member is mounted for radial movement into and out of engagement with the major thread to permit manual operation of the door.
