Abstract: Rotary printing presses of the type embodying abutting plate cylinders and impression cylinders. Particularly, a bell crank mechanism pivotally mounted upon the press and connected to an eccentric bushing plate supporting the impression cylinder shaft, so as to apply impression or space the impression cylinder shaft with respect to the plate cylinder for web adjustment, repair, plate changes and the like without stopping the press.

Abstract: Electronic articles, such as beam-lead semiconductor chips are temporarily held on a tape to retain them in a predetermined order to facilitate handling them and bonding them to a substrate. The tape has a plurality of evenly spaced pedestals in one face thereof. The chips are mounted to the pedestals. Edge lugs extend from the other face of the tape. As the tape is wound onto a reel with chips mounted to the pedestals, the edge lugs on each portion of tape separate such portion from chips mounted on an adjacent layer of the tape. This prevents such portion of the tape, as it is wound onto the reel, from contacting and thereby damaging the chips.
