Abstract: A process and apparatus for packing a stack of loads with synthetic resin films each possessing heat contractility. A plurality of loads are stacked on a pair of synthetic resin films placed in crossed relationship on an elevating table. The elevating table is movable downward from its upper extreme position so that the synthetic resin films are continuously supplied to cover side peripheries of the loads. Adjacent rib portions formed by side edges of the synthetic resin films covering the side peripheries of the loads are joined during downward movement of the elevating table. Upper opposing portions of each of the synthetic resin films are bent toward each other and joined together on the upper surface of the stacked loads on the elevating table. The synthetic resin films covering the loads are heated so that the films shrink.

Abstract: A novel arrangement and associated method for packaging glass doors and the like for shipment and handling, one requiring less time and materials and involving exposing the "breakable-glass" character of the contents in full view to handling personnel, as a cautionary measure -- this method, in one embodiment involving a wrapping of a bundle of glass doors in a packing strip to be spaced and cushioned around their edges; cinching of this bundle onto a pallet, and covering the palletized bundle with a transparent film, preferably by heat-shrinking a clear plastic envelope there-around.

Abstract: An acoustical imaging system wherein an acoustic beam projected through a transmission medium is modified (scattered) by a subject therein and impinges upon one side of an acousto-optic interface. The other side of this interface is made concave and mirror-surfaced to reflect an illuminating laser beam. The acousto-optic interface is "composite," being fabricated from an epoxy matrix with a multitude of tiny spherular capsules, or "microballons" distributed therein to thereby match the acoustic impedance of this interface to that of the transmission medium.

Abstract: Light emitting diodes are optically coupled to a photosensitive material through fiber optics. Incoming data are used to determine the emission of the diodes so that the incoming information is printed and stored as shades of grey. Tone and contrast control are provided, and either positives or negatives may be printed. Very high speed operation, on the order of gigabits per second, is currently feasible.

Abstract: An improved removable unitary product mounting structure for refrigerator cabinets; one adapted for easier, more convenient installation and removal and for more effective product display, comprising, in one embodiment, a pair of height-adjustable spring-loaded standards suspending a display backboard therebetween as an integral removable unit, the backboard being adapted for selective mounting of product carriers.

Abstract: A door stop and hold open for use in refrigerated display cabinets includes a selectively positionable arrestor for limiting the swing of the door and for detenting the door in its widest open position. Detenting action is provided by a clip having two leaf springs between which a pin is forced as the opening door approaches its limiting position, and by which the pin is yieldably retained. The leaf springs are shaped to provide rigidity except in the direction of spreading and to provide a large surface area for contacting the pin, thereby reducing wear.
