Abstract: Arrangements for clamping a large workpiece such as an I-beam to a precision assembly table (or fitup table) or other workpiece support. The clamping arrangement includes a base; a first track supported by the base; a first slider for sliding along the track; a second slider for sliding along the first track, wherein the first slider and the second slider are moveable relative to one another along the first track; a first spacer supported by the first slider; and a second spacer supported by the second slider; wherein the first spacer and the second spacer are adapted to grip the workpiece therebetween.

Abstract: In the context of precision assembly tables for box beams and components and systems associated or connected with such assembly tables, innovations including but not limited to: fitup arms of a generally “scissors” configuration, a control system for such fitup arms, automatic and manual clamps that can be employed with such fitup arms or other fitup arms, an overall rapid configuration system and process for fabricating trapezoidal box shapes.

Abstract: A completely self contained robotic cell (or modular unit) disposed on air pallets. Also preferably included on the cell also are crane lift points. Thus, these measures allow the cell to be moved within a defined area in a shop, to a different area in a shop, or to other sites such as job sites. Preferably, the cell is also built to dimensions that allow for easy transport by truck to a job site, and are configured as to be stackable with other cells when not in use.

Abstract: The disclosed semi-buoyant lift-augmented aircraft, preferably of immense size, includes a fuselage of airfoil shape formed by a rigid geodesic type web framework enclosing buoyant cells pressurized to reinforce the framework. Wings are provided which impart aerodynamic lift to the aircraft, with the airfoil fuselage. The buoyancy is provided to counteract a major proportion of the great weight of the structure and to thus improve the aircraft's payload capability and range. These features maintain it airborne at reasonable speeds over a substantial altitude range.
