  • Seedling growth enhancing device
    Patent number: 6263613
    Abstract: A seedling growth-enhancing device is disclosed, consisting of a circular tube formed from flexible, non-opaque thermoplastic material having a slit formed over its length. The tube is of sufficient size as to substantially enclose the seedling, and the plastic material is inherently resilient so that the device is normally biased into its tubular configuration. The opposed edges of the slit are fastened at the top and bottom to permit the edges to be resiliently spread at an intermediate point to permit access to the seedling for maintenance. Also disclosed are an H-clip for releasably fastening the opposed edges and a wire hanger for suspending the circular tube from an overhead suspension wire.
    Type: Grant

  • Nuclear fuel element having a composite coating
    Patent number: 4473410
    Abstract: A nuclear fuel element consisting of a zirconium or zirconium alloy container and nuclear fuel pellets is provided for use in the core of a nuclear reactor. The zirconium or zirconium alloy container has an inner coating of copper in proximity to the nuclear fuel, and is separated from the zirconium or zirconium alloy by an intermediate zirconium oxide diffusion barrier layer. The copper layer and the intermediate zirconium oxide diffusion barrier of the composite cladding reduce perforations or failure in the zirconium or zirconium alloy cladding substrate caused by stress corrosion cracking or metal embrittlement. Good bonding of the copper to the oxide zirconium and zirconium alloy prevents scaling of copper from the composite cladding during the loading of the fuel element with fuel pellets.
