Abstract: An apparatus and method for storing gases and liquids having a high trans-migration rate through containment surfaces due to their molecular size. An inner pressurized retaining enclosure for the storage of gas and liquids has a second enclosure wall about the first enclosure defining a gap between the respective enclosure surfaces which is filled with a containment gas or liquid having a molecular size greater than the porosity of the storage wall and stored gas or liquid. The containment gas effectively impedes the transmission of the storage gas and liquid through the first inner pressure retainer enclosure by creating a pressure barrier on its outer surface.

Abstract: An improvement in a bridge conveyor for a rotary stretch film wrapping apparatus for wrapping a product in a plastic film. The products are conveyed to a transition bridge around which the elongated shrink film is wrapped. The improved bridge conveyor system includes a pair of horizontally spaced air assisted guides adjacent an endless conveyor. The air assisted guides provide an air cushion on which the plastic film rides.

Abstract: The apparatus and method of this invention safely and efficiently loads and unloads the contents of a load transport container. A manipulator mechanism such as a backhoe having a hemispherical spiked tool at the end of a manipulator arm is mounted on a telescoping conveyor belt system. Right hand and left hand 1/4 turn drive conveyors are used at the front end of the telescoping conveyor belt system to facilitate movement of cargo from the front end of the system to the discharge end. The main conveyor belt has a ribbed design.
