  • Patent number: 8516973
    Abstract: A support assembly has upper, lower and top-most plates. The upper and lower plates each have interior and exterior ends. The plates each have upper and lower surfaces and a plurality of upper, lower and top-most plate holes. Left and right fingers extend downwardly from the upper and lower plates at an angle from the vertical. Two laterally spaced pole-holding tubes are secured to and extend upwardly from the top-most plate. Each tube has an upper end with a short vertical slot for receiving a reel of a fishing rod.

  • Patent number: 6238594
    Abstract: An intumescent material includes a liquid carrier with a corrosion inhibitor, such as a coating forming material, expandable particulate graphite (flake graphite or lump graphite) and if desired a filler. The intumescent material has a pH greater than 7.0, to reduce the corrosive properties of the intumescent material for most metals used in the construction industry and to provide a chemical environment conducive to the forming of a corrosion inhibiting layer by the corrosion inhibitor. The method of making the intumescent material includes combining the liquid carrier, the corrosion inhibitor, the expandable particulate graphite, the filler (if used), and a pH enhancer (if necessary to bring the intumescent material within the desired pH range), to form an intumescent material having a pH greater than 7.0.
