The spacing sheets are generally thicker than a conventional paper tie sheet while being thinner than a conventional pallet.

Abstract: An apparatus and method for providing a removable closure seal between the toner hopper and the toner feed roller compartment of a toner cartridge assembly used in printers, copy machines and facsimile machines. The seal prevents toner from leaking from the toner hopper into the feed roller compartment during shipping and handling. In one embodiment, the seal has a slotted seal insert placed over the passage between the hopper and roller compartment. A removable tape closes the slot. In another embodiment, a slotted seal insert is slid between grooves in the toner cartridge assembly into position between the hopper and feed roller compartment. The insert is attached to the cartridge assembly by glue, tape, or other adhesive. An insert tool is used to facillitate this attachment. A reusable, removable closure seal is slid between the grooves to close the slot. The closure seal may have a metal spine to increase its rigidity.

Abstract: The present invention relates to a container with a chain retaining opening. The container includes a side wall which defines an enclosed chamber for receiving a length of chain. An opening provides access to the enclosed chamber from an exterior of the container.

In order to ensure reliability in the computed value of BOD, the chamber of the respirometer incorporates a framed structure.

Abstract: Trapezoidal sections are simultaneously heat sealed and cut from a long strip of sheet plastic folded over double or in tubular form. Cutting one long corner and inserting air opens the interior volume of the trapezoid. Crimping the long ends horizontally, with the trapezoidal plane held vertically, and heat sealing one bottom end forms a tent-shaped paint bag. The paint bags are placed in a molded tote tray and gang filled through the cut ends and a number of the cut ends heat sealed simultaneously by a bar sealer. The molded tote tray is also used to transport and display the paint bags. Each paint bag fits into a paint applicator having a tent-shaped receiving space directly contacting a paint pad with multiple holes. The paint bag is punctured and squeezed to supply paint continuously to the pad through the holes. A tubular sheet of plastic creates disposable paint bags filled through one of the bottom ends before sealing. Folded over plastic sheets create open-topped refillable paint bags.
