  • Low profile raised panel flooring with metal support structure
    Patent number: 5499476
    Abstract: A raised flooring system and methods of forming components of such a system are disclosed. Systems consistent with embodiments of the present invention utilize thin sheet metal, typically galvanized steel, base plates laid side by side on an existing floor. Attached in a rectilinear pattern to the base plates are stand-offs, which support floor panels forming the raised or false floor (which in turn are typically covered with carpet tile). In addition to supporting the floor panels, the stand-offs form a network of channels where conduit, cables, hoses, pipe and similar materials can be routed. The stand-offs are punched and then formed from thin sheet metal, also typically galvanized steel, and have an overall shape generally that of a truncated cone achieved with four arms that have rolled edges for enhanced load-bearing capacity.

  • Bovine endothelial nitric oxide synthase nucleic acids
    Patent number: 5498539
    Abstract: The cloning, nucleotide and deduced amino acid sequences of the gene encoding endothelial nitric oxide synthase are described. The sequence contains binding domains for calcium/calmodulin, FMN, FAD and NADPH. The enzyme has a molecular weight of 133,413 M.sub.r. The amino terminal portion of the enzyme exhibits a proline-rich region and several sites for proline-directed phosphorylation as well as a potential substrate site for acyl transferase. DNA probes prepared from the nucleic acid sequence are useful in research and diagnostically to determine the level of nitric oxide synthase mRNA expressed by endothelial cells both in cell culture and in intact tissues. These probes are also useful for detecting genetic abnormalities. The nitric oxide synthase gene is transfected into blood vessels in vivo for enhanced synthesis of nitric oxide synthase, resulting in increased production of nitric oxide.

  • Fire extinguishing panels
    Patent number: 5490566
    Abstract: Fire extinguishers include portions formed of heat fusible material that contain powderized fire extinguishing material. The heat fusible material releases the fire extinguishing material upon exposure to predetermined temperatures, and is preferably self-extinguishing. Such extinguishers may contain collection layers which collect the heat fusible material during a fire in order to minimize future gratuitous untidiness otherwise caused by coagulated heat fusible material on floors, furniture, and other surfaces. The extinguishers may conveniently be formed in panels which may supplant SHEETROCK.RTM. or ceiling panels, and thus escape notice of the casual observer. Similarly, a collar according to the present invention may be placed around the flue of a kitchen ventilator and effectively fight fire but remain out of sight.

  • Telescoping rigid frame and scissor conveyor
    Patent number: 5490592
    Abstract: Telescoping rigid frame/scissor conveyors. Such conveyors are formed of a plurality of telescoping frame segments which may be positioned at any number of desired nested/unnested configurations. The frame segments bear a lazy tong or scissors conveyor structure which assures uniform roller spacing, and rollers positioned at one height along the conveyor rather than at different heights for each frame segment. Counterintuitively, the increased structural complexity is more than outweighed by the benefits resulting from the uniformly positioned rollers of a uniform height, which are thus adapted to convey articles in a reliable and jam-free fashion unlike previous expandable rigid frame conveyors. Conveyors according to the present invention may contain automatic locks to prevent overextension, powered rollers and motive devices for automatic and reliable extension and retraction.
