  • Patent number: 6412325
    Abstract: A method for prototyping parts from a sheet metal blank in which the sheet metal has at least two spaced edges. The method includes the step of forming a plurality of longitudinally aligned slots through the sheet metal blank to form a bend line extending between two spaced edges on the sheet metal blank. The slots are preferably formed by laser cutting. The sheet metal blank is then bent along the bend line to form the prototype.

  • Patent number: 5309846
    Abstract: A system is disclosed for creating a temporary grass playing field. The system includes a plurality of substantially identical pallets, each pallet having a base with a top surface and a bottom surface. The pallets are polygonal in shape and are adapted to abut against each other to form the playing field. Reinforcing brackets are secured to the bottom surface of the base to elevate the base above a ground support surface by a distance sufficient to enable the fork of a forklift truck to be inserted under the base and the lift the pallet. Grass sod corresponding in shape to the base is then supported on the top surface of the base. This grass forms the temporary grass playing field when the pallets are nested together so that the sides of the pallets abut against each other.
