  • Adjustable Truss Pick
    Publication number: 20180245715
    Abstract: The present invention relates to the field of hanging tubular space frame truss (“truss”) using truss picks. Truss units include tubular longitudinal truss chords, and tubular webbing elements interconnecting the truss chords. Truss picks attach to truss via the truss chords. Prior art truss picks were rigid and therefore incapable of adjusting attachment locations to account for variations in truss chord spacing. The invention described herein provides an adjustable truss pick having a swiveling saddle and clamp assembly that, as a result, creates adjustable spacing of truss pick attachment locations long desired in this field.

  • Screen printing frame having prestressing reinforcement
    Patent number: 6732640
    Abstract: A frame for supporting the screen of a screen printing machine having elongated frame members coupled together each providing support for an edge of the screen. The frame further includes a reinforcing member supported by the frame to extend in intimate proximity along at least a portion of at least one of the frame members to provide a prestress and/or camber of the frame member. The reinforcing member may include a cable extending within an interior of the frame member. The reinforcing member may also include an elongated secondary member affixed to the frame member while the frame member and secondary member are subjected to an applied condition imposing differential strains on confronting surfaces of the frame member and secondary member.
