Abstract:

A rearrangeable non-blocking three stage network and method for routing one or more requests between an input stage and an output stage, comprising between 3N and substantially the next largest integer of (41N-E. sub. N)/16 center stage interconnection units, where N is the greater of the inlet links to the input stage and outlet links from the output stage. Received requests are grouped by load size into a first group, a second group, and a third group with the second ground divided into a first half and a second half. The requests in the first group and first half of the second group are routed by a first set of center interconnection units, and the requests of the second half of the second group are routed by a second set of center interconnection units. The requests of the third group are routed through the first and second set of interconnection units so long as their load capacity is not exceeded, while any remaining small requests are routed through a third set of interconnection units.

Abstract:

A shopping basket is comprised of an arrangement of plural lazytongs frames movable from folded to extended position in which they constitute an erected structure having a floor provided by support bars, these support bars including long bars and short bars connected to the lower part of the enclosure. By selectively adjusting the effective lengths of the long support bars, the envelope and hence capacity of the erect structure can be changed. The structure can embody wheels and a handle thereon so that the basket serves as a readily movable shopping cart.
