Latest Patents

One of Brown's latest patents is titled "Method for Ablative Heat Transfer." This patent describes a unique method and apparatus designed for rapid heat transfer, utilizing surface-to-surface heat transfer of a solid or semi-solid feedstock against the inner surface of a containment vessel. The vessel is characterized by a torus or helically shaped design, allowing for the effective conveyance of feedstock through the vessel at a velocity that sustains the material against the outer periphery. This innovative design is particularly advantageous for pyrolysis of various materials, including waste rubber, municipal solid waste, plastics, and paper, allowing for the recovery of valuable petrochemical-based liquid reaction products along with solid reaction products. Additionally, this reaction vessel can be utilized for gasification and combustion reactions.

Another notable patent by Brown is the "Apparatus for Feeding a Mass of Particulate or Fibrous Material." This invention focuses on the compaction and advancement of particulate or fibrous material to a discharge end of a conduit. The apparatus integrates an auger with a reciprocating annular piston driven by a flywheel-equipped crankshaft. This design also incorporates a dynamically counterbalancing member to minimize vibrations transmitted to the frame. Special hydrostatic guide sleeves facilitate high-speed guidance of the reciprocating piston, while improvements like gas and liquid vents and a cooling jacket enhance the overall efficiency of the compacting process. A density sensor-controlled conical choke member at the discharge end ensures uniform density of the highly compacted material, improving subsequent processing.
