Bifurcation and chaos in dc - driven long Josephson junctions

A characters carrying aggregate or assembly for a printing machine includes a characters carrying disk carrying the characters on the outer ends of radial arms extending from the disk. The disk is mounted on a hub and may include a crown mounted opposite the hub. The assembly is manufactured on a base plate having at least two positioning pins corresponding to two positioning holes in the disk. The base-plate includes a central hole or protrusion for aligning with a central protrusion or hole in the hub. The base-plate further includes an alignment finger which extends through an orientation hole in the disk into a specific oriented alignment with an orientation hole in the hub. The aligned hub and disk are then secured together.
