Abstract: A connector component for computer units and peripheral units is secured to the back of each unit and enables the units to be stacked together in direct electrical connection, without the need for cables between them. Each connector component includes a pair of swivel mounts which rotate through 90 degrees and support a multi-contact pin connector, so that each connector can be oriented either vertically or horizontally, toward the rear of the unit. The pin connectors are internally connected to the operable portions of each unit by an internal cable bus. For direct interconnection between units, the adjacent swivel mounts are rotated to the vertical position and mated. At the top and bottom of a vertical stack of units, the extreme upper and lower swivel mounts may be rotated to the horizontal, rearward-facing position for connection to a cable leading to other computer or peripheral units remote from the stack.

Abstract: A container for use in the bulk handling of flowable particulate materials is disclosed comprising a closed, generally rectangular parallelpiped on upper container body portion, having side walls, end walls and a roof, and a lower base portion; conduits permitting the introduction and withdrawal of particulate materials to and from the container body; the lower base portion supporting a vertical flexure panel at each corner thereof, the vertical flexure panels supporting opposed pairs of longitudinal and transverse flexure panels between the tops thereof; exterior outer skin members bonded as side and end walls and roof of the container body portion to the curved flexure panels; a plurality of horizontal, non-intersecting internal end wall stiffeners bonded to each of the end walls, each terminating at opposite ends in a junction with one of the pair of vertical flexure panels; a plurality of vertical, non-intersecting internal side wall stiffeners bonded to each of the side walls, each terminated at opposite
