Abstract: A rotary assembly apparatus includes a base having a pair of parallel vertically oriented axes. A pair of circular platelike members of differing diameters are mounted for rotation, one on each axis such that the peripheries of the circular platelike members encompass both axes and are in juxtaposition at one point. Each of the platelike members includes on its periphery a plurality of receivers for receiving elements of a mechanical assembly from feeders positioned adjacent the periphery of the platelike members. The rotation of the platelike members brings a set of the elements into juxtaposition and one of the receivers moves vertically with respect to the other to complete the assembly of the elements.

Abstract: A holographic apparatus uses electronically processed three-dimensional information about an object to produce a three-dimensional display of that object and its movement. A holographic screen has a plurality of angularly multiplexed holographic images which are selectively illuminated by a modulator and light source to produce the three-dimensional surface outline of the object to be seen. Color encoding and rapid sequential presentation of images gives the effect of a full-cover, three-dimensional "television" in which movement of the object and both horizontal and vertical parallax can be provided.

Abstract: A serial-orienting and feeding apparatus is disclosed which includes a stationary support fixed substantially midway between the rim of a rotatable tub and the bottom of the tub. A disc is mounted for rotation on the support surface, the surface configuration of the disc being defined by the support surface such that the uppermost portion of the periphery of the disc is immediately adjacent the rim of the tub. The rim and tub are coaxially driven by a common motor driving a two-ended reductor having a chain and sprocket drive on each end. The relative angular velocities of the tub and disc are determined by the sprocket sizes employed. The disc is preferably composed of an artificial resin; i.e., a molded or cast plastic, such as urethane having appropriate elastomeric and surface friction characteristics relative to the articles to be handled by the apparatus.

Abstract: A walking beam conveyor having a cam at only one of its ends. The conveyor includes a framework, a longitudinally extending beam having proximal and distal ends, and a plurality of supports freely pivotally mounted in the framework for supporting the beam. The supports carry the beam in such a manner as to allow the beam to move longitudinally of the conveyor with respect to the supports. A first follower, movably mounted in the framework, follows the cam and a first linkage apparatus connects the first follower to the supports. The supports pivot about their connections to the framework in response to movement of the first follower to move the beam transversely of the conveyor, e.g., vertically. The supports engage an equal plurality of beam guides to which the beam is attached. A second follower, also movably supported in the framework, and second linkage apparatus coupled to the second follower and the beam, move the beam longitudinally of the conveyor, e.g., horizontally.
