Abstract: The present invention is an ink fountain liner and blade guard adapted for prolonging the life of an ink fountain blade and controlling the temperature of the ink by eliminating metal to metal friction and reducing cleaning time and cleaning materials. The liner covers the bottom surface of an ink fountain and includes a strip of double sided adhesive with a backing strip preserving the side of the adhesive not affixed to the liner. The front edge of the preferred embodiment is connected at a creased line to a flap that covers the ink fountain blade.

Abstract: A new building structural system is described that employs unique elements to interconnect standard structural members in a simple, economical and effective manner. These unique interconnecting elements interconnct a girder and a span member of a building structure, the span member being either a joist or a truss. They consists of two interlocking pieces or elements, one connected to the end of the span member and the other to the side face of the girder member. These unique elements incorporate shaped involutions, webs and reinforcing members that interlock as one element seats down upon the other to interconnect the members in a rugged, rigid fashion. The resulting building structure provides both a flexibility of design and a simplicity of assembly that is remarkable.
