Abstract: A shingle and a method of hanging the shingle by a fastener driven by a nail gun. The shingle can be formed from slate or made of clay, ceramic, glass, or concrete. The shingle includes at least one aperture for a fastener. The aperture is spaced a predetermined distance from an upper end of the shingle.

Abstract: A one-way clutch includes a first race having mutually spaced pockets formed with an opening at a periphery of the first race, each pocket being at least partially bounded by a wall that extends along at least a portion of a margin of the pocket and contains a drive surface. A second race includes a series of alternating notches and cam surfaces formed on a periphery of the second race facing the openings. A plurality of rockers is located in the pockets. Each rocker includes an engagement surface for driveably engaging and disengaging a notch, a reaction surface for contacting the drive surface when the engagement surface driveably engages a notch, and guide surfaces for contacting the pocket wall to guide movement of the rocker from a disengaged position toward an engaged position. Springs, located on the first race, urge the rockers toward engagement with the cam surfaces.

Abstract: A one-way clutch includes a cam plate formed with notches, a rocker plate formed with pockets mutually spaced angularly about an axis, each pocket including an open axial end, and a surface that closes each pocket at an end opposite the open axial end of each pocket. A rocker is located in a respective pocket for movement toward and away from engagement with a notch on the cam plate. Springs are supported on the rocker plate, each spring urging a rocker toward engagement with a notch.

Abstract: A space shuttle mail box with nose cone delivery door, tail end delivery door, raisable tail flag and mail box post support. Each of the components structurally resembles a United States Space Shuttle and further includes perpendicular main sidewings, O.M.S. thruster pod protrusions, and dome shaped protrusions extending rearwardly from the tail end delivery door. Both the tail end and the front end nose cone can pivotally open relative to the main cargo bay section in order to put mail into the cargo bay interior.

Abstract: An automatically positionable rear view mirror assembly for automotive vehicles having a turn signal lever. The mirror assembly incorporates a housing that is supported by automotive vehicle and encloses a movable mirror assembly adapted for movement to first and second positions relative to the mirror housing. Motor means such as a solenoid motor is located within the mirror housing and includes an actuating shaft operatively interconnected with the movable mirror. The motor means includes a control circuit having a switch coupled with the circuitry of the automotive vehicle, the switch being operated by the turn signal lever of the automotive vehicle, whereby the mirror is automatically positioned responsive to selective positioning of the turn signal lever. The mirror assembly preferably includes a fixed mirror segment and a movable mirror segment, the movable mirror segment being operated by the motor means.

Abstract: A heat exchanger closure connection including a shell closure flange extending outwardly from the shell and including a shell closure flange sealing surface. A tube closure flange extends outwardly from an inner tube, which is positioned within the shell, and includes axially spaced apart first and second sealing surfaces. A first seal ring is positioned between the first seal surface of the tube closure flange and the shell closure flange sealing surface. A split ring assembly is fitted within a groove in the tube closure flange and in abutting engagement with the shell closure flange. A locking flange is positioned about the tube closure flange engaging the first seal ring.
