  • Publication number: 20110036050
    Abstract: A reinforced girder including a first C-shaped member formed of sheet metal. A second C-shaped member, formed of sheet metal, is welded to the first C-shaped member to form a box. A first pair of metallic stringer assemblies is welded in a spaced-apart relationship within the first C-shaped member. The first pair of metallic stringer assemblies extends the length of the first C-shaped member. A second pair of metallic stringer assemblies is welded in a spaced-apart relationship within the second C-shaped member and extends the length of the second C-shaped member. A first pair of transverse connector assemblies is welded into the ends of the first C-shaped member between the first pair of stringer assemblies.

  • Patent number: 5921053
    Abstract: A girder including a pair of C-shaped members secured together so as to form a hollow box. A number of reinforcing rods are secured within the C-shaped members. The reinforcing rods extend the respective lengths of the C-shaped members and are positioned side-by-side. A pierceable block is secured to at least one end of the hollow box. A pair of pierceable stringers are secured to the top and bottom of the hollow box. The pierceable block and stringers permit the girder to be secured within a building structure with conventional fasteners such as nails, screws and staples.

  • Patent number: 5027291
    Abstract: A method is described that gives local control to an application program during the drawing process when a "pickable" primitive intersects the pick window. This control is provided in such a way that the state of graphics workstation remains unaltered. Thus the application program is permitted to make "picking" or visualization decisions at the moment the pick occurs, and then resume execution of the display program wherever desired (typically, at the graphic instruction following the one that caused the pick). This capability enables application programs to provide greater functionality, usability and productivity to their users.
