Abstract: This invention relates to a new pallet lift system for the movement of pallets via the use of a new pallet jack and dolly in conjunction with new tines to transport the pallet from one location to another and minimize the risk of damaging or marring the surface across which the pallet is moved by utilizing a pallet jack and a dolly equipped with soft wheels to allow a pallet to move over door thresholds and floor surfaces without risking damage to the surface, and to facilitate the transportation of pallets of merchandise across an uneven surface such as a parking lot, and into and through a narrow entrance such as a standard doorway and provides a method to load pallets in and out of trucks with the narrow edge leading, thus increasing the usable space inside a typical truck, the present invention being able to be used with multiple different sized pallets.

Abstract: An envelope allows limited, yet sufficient, inspection of its contents for various types of contraband material, while simultaneously maintaining the privacy of a substantial portion of its contents. The envelope's front panel, back panel, and closure flap are each substantially opaque, and at least a portion of at least two of its edge portions on at least one of the front and back panels, are substantially transparent.

Abstract: Improved stabilization of 1,1,1-trichloroethane is obtained by employing a free radical scavenger as a stabilizer which will trap trichloromethyl radicals, making them unavailable for formation of acidic species in the trichloroethane. Examples of such free radical scavengers include trichloroethylene, tetrachloroethylene, or fluorene. Compositions in accordance with the invention consist essentially of the 1,1,1-trichloroethane and from about 0.1 volume percent to about 5 volume percent of the free radical scavenger. In the fabrication of semiconductor devices in which the so stabilized trichloroethane is employed as a degreasing solvent, the acidity of the trichloroethane composition may be monitored, and additional free radical scavenger added to the solution to maintain the acidity within acceptable limits, thus allowing the trichloroethane to be used indefinitely.
