  • Apparatus and method for solar heat collection
    Patent number: 12405012
    Abstract: Subterranean thermal capacitance for an environmental-control apparatus mechanized via a solar thermal system. The method and apparatus use a solar collector and a plurality of heating-energy-storage cells that are each thermally insulated from one another, wherein heating energy-transfer fluid (HETF) coming from the solar collector is transferred to the energy-storage cell having the highest temperature that is greater than the temperature of the HETF, in order to segregate energy-storage cells to more efficiently store heating energy.
    Type: Grant
    Filed: July 14, 2020
    Date of Patent: September 2, 2025
    Assignee: Lasting Image Laser Etching Company
    Inventors: Daniel S. Hokanson, Greg M. Smith

  • Solids produced from ash and process for producing the same
    Patent number: 6180192
    Abstract: A compressed solid produced from a feed mixture of bottom ash and a binder. The feed mixture includes about 80% to 95% by weight bottom ash, or at least about 50% by weight bottom ash in combination with other waste materials, in combination with a polyisocyanate-based binder.

  • Bulk material shredder and method
    Patent number: 5601239
    Abstract: A bulk material shredding method, a bulk material shredder which has a shredder housing having a trough, a discharge end having a discharge aperture for discharge of shredded material out of the trough, and an opposite end remote from the discharge end, an auger mounted for rotation within the shredder housing and retained by a bearing surface at the discharge end of the shredder housing and by a bearing surface at the opposite end of the shredder housing, the auger having a uniform diameter auger flight, and a shaft of uniform diameter through its length which carries the auger flight. A drive means is located at the discharge end of the shredder housing for rotating the auger and a plurality of teeth are mounted on the periphery of the auger and project radially therefrom. Apparatus for shredding railroad ties and separating non-fuel useable components therefrom to produce fuel.
