Abstract
Abstract Positioning apparatus for effecting movement of a first body with respect to a second body in response to movement of a third body characterized by a slot traversal member engaging a set of driving slots and a set of driven slots that are formed respectively in the first and second bodies. One of the sets of driven and driving slots comprises a closed pattern of slots; and the other comprises a single slot having at least two portions that have the same design and are movable so as to be coextensive with the slots of the closed pattern of slots. Also disclosed are tubular and planar constructions employing the driving and driven slots.
