Abstract: Holographic lines are formed directly on products by holding a holographic plate and a block under a lip on a frame and mounting the frame for limited movement within a recess in a mold half. As a mold cavity is filled, the frame, block and plate and heating tubes connected to the block move in the recess. As the product sets, springs push the frame, block and plate toward the shrinking product controlling the fine holographic lines. Lateral frame recesses receive bolt ends to limit frame travel. Partially withdrawing bolts and removing the tubes releases the frame for withdrawing the block and replacing the holographic plate.

Abstract: Creased paper board packages are unstacked, separated and conveyed. Discs are loaded into dimensionally controlled trays using relatively fine alignment, placement and assembly tolerances. Subsequently, the disc-loaded trays are assembled onto less dimensionally controlled tray-holding panels on creases paper boards using relatively less stringent tolerances. Booklets are inserted in pockets in panels adjacent the disc-holding panels, and the paper board packages are closed.

Abstract: The new buckle is made of two pieces which work with laminated strap webbing or open weave strap webbing. Web engagements within the buckle prevent the web from sliding through in any direction, or allow the belting to move in only one direction. Bases of side extensions of the inner plate have locking lugs. Moveable rounded side portions of the outer plate have locking tabs which engage the lugs to prevent movement out or into the locking position. Locking and unlocking the buckle requires squeezing rounded sides together while pushing or pulling on the outer plate. Teeth extend inward from the outer locking plate. Angled through-holes in the lower plate receive the teeth and hold the locking teeth in engaged position when the buckle is locked. Locking teeth angularly mounted in recesses in the upper plate are deflected when the webbing strap is pulled in a tightening direction.
