  • Patent number: 6360510
    Abstract: A stud for a modular building system. The stud comprises two elongate channel members secured together, with each of the channel members have a generally hat-shaped cross section. The channel members each have a bottom web, and a first and second side web. the side webs extend perpendicularly and upward from opposite sides of the bottom web. The channel members further comprise a first and second flange that extend laterally from the first and second side webs respectively. In one aspect of the invention, each flange comprises a first segment extending generally laterally outward from the upper edge of its respective side web and a second segment folded back upon the first segment and extending back toward the side web. In another aspect of the invention, the second segment overlaps and overlies the underside of the first segment, and the fold or crease between the first and second segments, has a rounded profile and forms a bead at the edge of each flange.

  • Patent number: 6328146
    Abstract: A piece of baggage is provided with a retractable pocket that is configured to support a beverage container on the exterior of the piece of baggage. The pocket is constructed of a mesh material and has an elastic strap along an upper edge that allows the pocket to expand to support various size containers, such as bottled water. When not in use, the pocket can be held collapsed against or inside the piece of baggage by a closure mechanism such as a zipper. This conceals the pocket to improve the aesthetic appearance of the piece of baggage and reduces the risk of snagging the mesh pocket as the piece of baggage is transported.

  • Patent number: 6326354
    Abstract: A novel p15 BID polypeptide having cell death agonist activity is disclosed. The p15 BID polypeptide is produced by caspase-cleavage of BID in cells undergoing cell death mediated by TNF or FAS receptors. The p15 BID is useful in methods for modulating death of a target cell which comprise treating the cell with p15 BID. Methods for inhibiting cell death are also described which involve treating a target cell with a mutant p15 BID lacking cell death agonist activity.

  • Patent number: 6318955
    Abstract: An apparatus that is one part of a conveying system for transferring objects, such as bottles, removes layers of the objects from a pallet on which the layers have been stacked or, in reverse operation, arranges the objects in layers stacked on one another on a pallet. The apparatus may be employed to depalletize objects or to palletize objects, wherein in the depalletizing mode of operation the apparatus has a slipsheet retainer that holds a slipsheet below a layer of objects being depalletized from the stacked layers of objects on the pallet and prevents the slipsheet from moving with the layer of objects as the layer of objects is depalletized.
