Abstract: A transfer case adapted for use in a four-wheel drive vehicle having two-wheel drive and four-wheel drive operating modes. The transfer case includes an inter-axle differential which permits general vehicle operation in the four-wheel drive mode. The transfer case also includes a chain and sprocket assembly which provides selective power transfer to one of the vehicle axles, normally the front axle. In the first operating state of the transfer case the chain and sprocket assembly is engaged with the inter-axle differential to transmit the drive torque to the front axle. In a second operating state, the chain and sprocket assembly is disengaged and no drive torque is transmitted to the front axle. The transition between operating states is effected by shifting of a clutch collar within the transfer case to control the engagement of the chain and sprocket assembly. This shifting is accomplished by controlled actuation of a vacuum motor.

Abstract: A technique for finishing a diamond ground outer surface (14) of a hot glass sheet conveyor roll (16) made of sinter bonded fused silica particles utilizes a continuous abrasive belt (26) to perform a finish grinding process on the outer surface. The process is performed by rotating the roll (16) about a central axis A thereof and driving the continuous abrasive belt (26) so as to finish grind the roll while moving the driven belt along the roll length. Silicon carbide is preferably utilized as the abrasive of the belt (26). The belt is preferably driven so as to engage the rotating roll surface (14) in an oppositely moving relationship and is moved in both directions along the length of the roll. During the finish grinding, the roll is flooded with water to provide a lubricant that dissipates heat and removes ground off particles. The ground outer surface (14) includes projections (55) having top surfaces (56), sloped sides (58), and curved junctions (60) connecting the top surfaces and the sloped sides.

A camming surface (36) on each jaw is engaged by a camming surface (44) on a sleeve (38) of the socket and defines an angle greater than 90.degree. with the path of jaw movement so as to facilitate jaw adjustment and prevent any binding of the jaws during such adjustment.

Abstract: A three cushion convertible seat-bed is disclosed. A single seat has first and second panels (12,14) for the seat back and seat bottom mounted on a seat base (10) and a third panel (16) pivotally coupled with the seat back. A conversion mechanism (18) includes a quadrant plate (80) which is pivotally supported on the base (10). The lower part of the seat back is rigidly connected (84,86) with the quadrant plate (80) and the rear edge of the seat bottom is pivotally coupled (124) with the quadrant plate so that the three panels can be unfolded from the seat orientation to a bed orientation. A first set of latches (A, B, D) holds the conversion mechanism (18) in the seat orientation and are released sequentially by moving an operating handle (22) in one direction. This same motion of the operating handle (22) causes an actuating means (172,170) to thrust the third panel (16) rearwardly toward the bed orientation as the first and second panels (12,14) are unfolded.

The holder surface is disclosed as being both planar and curved and as having a porous cover of ceramic fibers so as to distribute the vacuum and prevent marring of the glass as it is supported. A greater vacuum is drawn to initially support the glass and a lesser vacuum is subsequently drawn to prevent glass deformation at the spaced openings.
