Abstract: The yaw control in an air vehicle having counter rotating rotors is provided by selectively and controllably applying a frictional drag or braking force to drive gears for the two rotors. Each of the drive gears includes a friction surface. Friction pads are located adjacent to and are releasably engagable with the friction surfaces of the drive gears. The friction pads are supported by a control mechanism for selectively moving each of the friction pads into engagement with the respective drive gear to provide a frictional drag on the drive gear and to a disengaged position spaced from the respective drive gear. The frictional forces created by engagement of the friction pads with the drive gear friction surfaces cause net torques on the air vehicle frame to rotate the air vehicle in the desired directions. Normally, the torque developed the counter rotating rotors is canceled, maintaining the air vehicle in the desired yaw orientation.

Abstract: An adapter assembly is used in combination with a door of the type having an elongated opening to receive a bolt extending from a lock which is mounted in a door coupled to the frame. The adapter assembly comprises an elongated strike plate, mounting means for coupling the strike plate to the frame in one of two inverted positions and an adjustable cover. The strike plate has an elongated, generally rectangular aperture longitudinally offset toward one end of the strike plate. The adjustable cover is coupled to the strike plate for closing at least a portion of the strike plate aperture and the opening in the door frame. This provides a simple mechanism for customizing the opening in the door frame to any one of a wide variety of different lock and knobset arrangements by varying the size and location of the opening.

Abstract: A frame assembly for mounting a light in a door comprises inner and outer half-frames which sandwich a translucent panel therebetween. Each half-frame is substantially identically formed as a unitary member from sheet metal and has a plurality of substantially identical side members which define a closed polygon.

Abstract: A mounting plate having three knockouts for three bolt locations of a deadbolt lock is mounted behind a rectangular opening in the edge of a hollow door. A filler plate and a cover plate are provided to cover the unused ones of the knockouts. When no deadbolt lock is installed in the door, the entire filler and cover plates are used to substantially fill the rectangular opening. When a dead bolt is installed in the door, a knockout is removed to leave an opening at the proper location for the bolt to pass through. The deadbolt lock bore drilling is made on the selected centerline either by the distributor or installer. The filler and cover plates are broken along weakened separation lines and appropriate portions thereof are attached to the mounting plate to cover the unused knockout locations. An adjustable backset lockset mounting arrangement is mounted adjacent the rectangular opening to receive and support the lockset in either of two positions. Breakouts in the door are preformed.
