Abstract: A machine for the manufacture of a panel file for the storage of flat, flexible data elements is herein disclosed. A sheet of flexible resilient material is unrolled from an arbor. The material is cut into strips and rolled onto reels. The strips are substantially narrower than the depth of the pockets to be formed in the panel file. The reels are mounted on a strip aligning mechanism so that as the strips are unloaded from the reels they are in a parallel overlapping relationship. The strips are then pulled through an accumulator and placed in a heat sealing die. In the heat sealing die, the strips are joined to each other proximate the ends thereof to form a layered panel of overlapping pocket entrances. Also in the heat sealing die, a pocket forming sheet is attached to the back of the layered panel of strips.

Abstract: An animated display showing the Nativity scene. Human figures representing the Wise Men, shepherds, etc., move past the crib containing the infant Jesus. Each figure pauses, turns towards the crib, bows, turns back, and then moves away. The pausing action is created by a drive gear with some missing teeth. The turning action is created by two racks which mesh sequentially with a gear on which each figure is mounted. The bowing motion is created by a hinge mounting for each figure, and a push-rod actuation mechanism.
