Abstract: Fibrous board transition parts are produced on the job site from standard lengths of preformed fiberboard duct units. Transition parts are interposed between linear runs of duct pieced together to change direction of the duct work. The transition parts, sometimes referred to as elbows or bends, can be easily fabricated on the job site by modifying standard lengths of preformed linear duct by cutting and removing pie-shaped sections from the duct. The modified duct can be bent inwardly to form a one-piece arcuate transition part wherein the outer wall section remains intact and provides structural strength to the transition part. The seams are secured with structural adhesive tape wrapped around the transition part.

Abstract: A mat cutter employing a razor blade and providing protection against the blade's bending towards either of its sides. The cutter, used for preparing mats for photographs and other art objects, has a base upon which it sits and a section which slopes upward. A holder for a razor blade pivotally attaches to the sloping section and can rotate the blade into and out of a cutting position.

Abstract: The method hereof, conducted at the factory or site of printing of the wall covering, advantageously uses the same work or printing station reference that accurately positions the imprinted pattern on the wall covering substrate for the positioning of cutting means effective to sever said substrate free of the opposite unprinted selvage areas. Thus, although the substrate, which typically is a 100-foot strip, may be inadvertently slightly misaligned from a perfectly straight orientation, the cutting means nevertheless effectively moves along that path which accurately slits free the selvages of the "misaligned" substrate because it is guided by said imprinting reference during said movement.
