Abstract: A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.

Abstract: A robotic system for handling components during chromatographic analysis of a sample includes a holder for positioning a sample within a separation pathway, the holder including a first opening having an internally tapered shape and a second opening having an externally tapered shape. An interior of the holder, between the first and second openings, defines the separation pathway. A hollow rigid member has an externally tapered shape, and a receiving portion has an internally tapered shape. The holder is positioned between the hollow rigid member and the receiving portion, wherein the externally tapered hollow rigid member engages the internally tapered first opening and the internally tapered receiving portion receives the externally tapered second opening to provide a sealed separation pathway extending from the hollow rigid member to the receiving portion.

Abstract: A leptin binding protein, inter-alpha-trypsin inhibitor heavy chain related protein (IHRP), specifically binds leptin, the obesity gene product. The specific leptin binding proteins enable modulation of free leptin levels, immobilization and assay of bound/free leptin.

Abstract: The present invention provides anti-obesity proteins, which when administered to a patient regulate fat tissue. Accordingly, such agents allow patients to overcome their obesity handicap and live normal lives with much reduced risk for type II diabetes, cardiovascular disease and cancer.

Abstract: A portable hunting stand which is adapted to be retro-fitted to a three wheeled motorcycle, ATV or the like for permanent operative association therewith may be deployed by a hunter or the like in a low profile ATV-transportable position, a cage position providing an enclosure, or a hunting position for seating the hunter in a secure elevated position above the terrain. A plurality of upwardly extending, rigid support stanchions operatively disposed generally at the vertices of the standard ATV rectangular deck support a chair support plate coupled to the stanchions. An associated foldable footrest may be deployed to provide a firm footing and to brace the elevated chair upon which the hunter may sit. A front stabilizer leg associated with the front of the chair provides a stabilizing connection to the chair support plate.
