Abstract: A selectively reversible video cassette tape includes a housing with a supply reel and a take up reel rotatably mounted therein. A video tape is connected at one to the take up reel and at the other end to the supply reel and is operable therebetween. Apparatus is mounted within the housing to prevent counterclockwise rotation of the reels, yet permit clockwise rotation of the reels, to thereby prevent rewinding of the video tape. Apparatus is also provided which will selectively permit the rewinding of the video tape.

Abstract: An apparatus for connecting castings includes an elongated screw having a threaded shank and head, a washer mounted on the screw, and a rigid bracket removably and operably mounted on the screw shank. Each connecting apparatus is mounted between the abutting edges of a pair of castings, so as to align and retain the castings in their aligned position. The castings each include a vertical edge having a flange therealong with a generally flat exterior surface, such that the exterior surfaces of the flanges of abutting castings will be parallel and adjacent. The connecting apparatus bracket has a pair of diverging legs which will engage the vertical flanges when moved along the screw shank towards the screw head. Each casting also includes upper and lower flanges, the flanges of a pair of castings being positioned in abutting contact so as to stack the castings. The screw of a connector apparatus is interposed between the abutting flanges with a washer abutting the exterior surfaces of the castings.
