Abstract: A system for controlling acoustics and emissivity in an arena having a ceiling includes a pair of rollers mounted adjacent the ceiling and spaced apart over at least a portion thereof. A plurality of acoustics and emissivity controlling panels connected together to form a continuous sheet are mounted between the rollers for movement across the ceiling when the rollers are rotated. The panels include one having a high emissivity surface of at least 90%, one having a low emissivity surface of 7% or less and one having an acoustical surface with sound absorbing characteristics.

Abstract: This invention relates to a collapsible box for shipments between plants of heavy loads up to 5,000+ pounds per box for heavy parts. The box is designed to be collapsible to be returned flat for less shipping costs. The box is fabricated in an octagonal shape made from 8 sides of hardboard on the outside, and a sheet of aluminum secured thereto with hinges holding the sides together in an octagon with strips holding the box on a pallet.The hinges hold the sides together from the base on the pallet to the top of the box. The hinges are of two types. One hinge is a double pivot for opposite corners of the collapsed box, and it folds back on itself with two pivot points, shown in FIGS. 6 and 7. The other hinge folds from a flat position on the top or bottom of the collapsed position to a 45.degree. bend inwardly toward the assembled box with only one pivot point, shown in FIG. 4 and 5.

Abstract: A method of adjusting wheel loading in a trailer having a trailer body with apertured channel members on the bottom, a wheel bogie having a braking mechanism and a pair of apertured channel members on the top thereof which engage the channel members of the trailer body to permit relative sliding movement between the trailer body and the wheel bogie, a locking mechanism having a pair of movable locking pins for locking the trailer body to the wheel bogie when the locking pins are extended through the apertures in the channel members wherein the method includes the steps of assessing the wheel loading of the trailer, setting the brake of the wheel bogie, retracting the locking pins to permit relative movement between the trailer body and the wheel bogie, inserting a trailer slider stop pin in an aperture of each trailer channel at a position where the trailer body is to be stopped relative to the wheel bogie and moving the trailer body relative to the wheel bogie until movement of the trailer body is arrested b

Abstract: A dry abrasive delabeling apparatus for both plastic and glass bottles, sometimes called a label stripper, in which the bottles are fed by an in-feed starwheel to a circular starwheel which rotates the bottles slowly. Within the starwheel are wire bristle brushes rotating at a high speed against the bottles to flick off paper, foil, or plastic from the label on the bottle while restraining the bottle in close contact to the ends of the wire bristle by means of a rubber bladder to press against the bottles. The bottles are held against the wire bristles while the bottles are rotated as they are held against the bladder. The debris is vacuumed away from the apparatus.

Abstract: A hermetically sealed, electrically insulative enclosure (A) is surrounded by a Faraday cage (B). At least one electrode (C) is disposed within the hermetically sealed enclosure. The volume of the enclosure is selectively altered such that an initial charge density in the neighborhood of electrod changes, which changes the electrode potential. The change causes a current to flow to or from the electrode which returns the electrode potential and the electrode surrounding space charge toward an equilibrium condition. In one embodiment, a current measuring circuit (D) is disposed between the electrode and the Faraday cage to derive a measure of the current flow therebetween. In another embodiment, a like electrode is disposed within another hermetically, sealed insulative enclosure which is shielded by the same or another Faraday cage. In the second embodiment, the measuring circuit measures the current flow between the two isolated electrodes.
