Abstract: A dual pocket or envelope for CDs or DVDs is formed of two standard letter size sheets of 8½?×11? or A-4 size paper, which are bonded together around the edges of the sheets and centrally to divide the sheet assembly into two pockets which are substantially square to hold the discs. One of the sheets is die cut to form the upper edge of the pockets, with a closure flap also being formed above each pocket. Each closure flap may be held in the closed position by mechanical interlinking with the pocket, or by exposed pressure sensitive adhesive, which is enabled and exposed by the removal of a release coated slip of paper from one of the two sheets. An index tab may be die cut from said sheets above the open edge of each pocket.

Abstract: A tool storage container has a base member with a tool receiving member. A cover is coupled with the base. An opening is in the cover. The opening may have a configuration corresponding to the tool maintained within the carrying case or any other configuration which enables viewing and prohibits removal of the tool when the container is in a closed position. A plurality of storage areas are within the inside of the cover. Also, fingers secure the tool in the carrying case so that in an open condition, the tool is maintained in the carrier.

Abstract: A hub for holding a disc-shaped item of recorded media includes a plurality of holding arms that engage the central opening of the disc-shaped item of recorded media to hold the item in a holding position. The hub also includes lifting arms that engage the inner lower edge of the disc-shaped item of recorded media to force the item upwardly with respect to the holding arms. The holding arms and lifting arms extend from opposite portions of a base member which may be in the form of a circular outer wall.

Abstract: A carrier for elongate, cylindrical chalk sticks comprises a body of flexible material having opposite ends, opposite sides, and inner and outer surfaces. Chalk stick pockets extend into the body from the inner surface toward the outer surface in four rows spaced apart in the direction between the opposite sides and each row includes 50 pockets spaced apart in the direction between the opposite ends. The pockets are elongated in the direction between the opposite sides of the body, and said body is rollable in the direction between the opposite ends to form a roll enclosing said pockets and which roll can be releasably held in the rolled condition by suitable fasteners.

Abstract: A lockable media storage box and lock and key combination includes a box having a base and a lid hingedly connected to the base and movable between opened and closed positions. A locking tab extends from the lid. The locking tab has a first hole therein. The base has a second hole therein. The first and second holes are aligned when the lid is in the closed position. A lock having at least one locking finger and at least one locking pin is attachable to the box by the locking finger. When the lock is attached to the box, the locking pin is disposed in the first and second holes to the prevent lid from being opened. Lock carries an EAS tag in a manner such that it cannot be easily removed.

Abstract: Workpieces such as sand-casted automobile engine blocks are cleaned by advancing a series of such workpieces axially into one end of an elongate, skeletal barrel that holds the workpieces and rotates or tumbles them in the path of impinging streams of particles. The workpieces are advanced from one end of the barrel to the other by oscillating the barrel along the longitudinal axis of the barrel. By this technique, workpieces can be advanced through the barrel without the need to push the workpieces against each other, or without the need to provide workpiece-engaging and advancing mechanisms.
