  • Patent number: 8256091
    Abstract: A method of producing equal-sized spherical shaped beads of a wide range of materials is described. These beads are produced by forming the parent bead material into a liquid solution and by filling equal volume cells in a sheet with the liquid solution. The sheet cells establish the volumes of each of the cell mixture volumes which are then ejected from the cells by an impinging fluid. Surface tension forces acting on the ejected equal sized solution entities form them into spherical beads. The ejected beads are then subjected to a solidification environment which solidifies the spherical beads. The beads can be solid or porous or hollow and can also have bead coatings of multiple material layers.

  • Patent number: 5928760
    Abstract: An abrasive sheet has an abrasive particle layer formed on a surface of a thin flexible resin film. The abrasive sheet is produced by the steps of preparing a releasable film, forming a thin flexible resin film layer on a release agent applied surface of the releasable film and forming an abrasive particle layer on an upper surface of the resin film layer. Thereafter, the resin film having the abrasive particle layer formed thereon is removed from the releasable film, and the resin film having the abrasive particle layer formed thereon is cut into any suitable size. The abrasive sheet can provide higher polishing power during the polishing operation, but it polishes a surface while tracing or following any orange peel on the surface. Therefore, the abrasive sheet is effective for use as the polishing tool that can replace the fine compound buffing process currently utilized in the automobile repairing industry.
