Abstract: Conduits, fittings, end closures, and couplers, particularly adapted for use as drain tile, are prepared by molding the items in a suitable mold with their respective ends closed. The ends can then be severed along cut lines directly molded, where desired. The items produced in accordance herewith are formed with helical threads to permit threaded interengagement therebetween.

Abstract: In a method and system for feeding prefolded recording web to a business machine, such as a computer, a plurality of receptacles containing the recording web are stored on upper and lower shelves of a portable rack positioned adjacent the computer. The shelves are spaced apart from each other by a distance sufficient to provide unobstructed flow of recording web from each of the receptacles to the computer. Any interference to the flow of recording web by the receptacles themselves is prevented by horizontal guide members attached to the rack. In one embodiment, the upper shelf has a width that is less than that of the lower shelf. This permits the rack to be located closely adjacent the computer while providing unobstructed flow of recording web to the computer from receptacles located on the lower shelf. In another embodiment, the lower shelf extends horizontally beyond the upper shelf to receive an additional receptacle for collecting recording web outfed from the computer.
