Patents by Inventor Michael F. Dallmer

Michael F. Dallmer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9023181
    Abstract: A pyrolyzer apparatus (i.e. a “cracking pipe”) comprises a first screen, a second screen, and a catalyst material positioned between the first and second screens. The pyrolyzer is structured so that feedstock is pyrolyzed and pyrolyzer-generated gas is drawn through the first screen, through the catalyst material, and then through the second screen in series. The gas may then be directed to other processing equipment so that bio-oil is extracted from the gas.
    Type: Grant
    Filed: March 25, 2011
    Date of Patent: May 5, 2015
    Assignee: The United States of America, as represented by the Secretary of Agriculture

  • Patent number: 7960574
    Abstract: Methods of separating oil from oil-containing seeds, involving aerating an aqueous dispersion of germ particles of oil-containing seeds (e.g., corn) to produce bubbles therein, whereby the oil in the aqueous dispersion adheres preferentially to the surfaces of the bubbles and are carried by the bubbles to the upper surface of the aqueous dispersion where a foam of the bubbles is formed; separating the foam from the aqueous dispersion; and recovering the oil from the foam. The aqueous dispersion of germ particles of oil-containing seeds may be produced by mixing corn germ separated from corn kernels with an aqueous acetate buffer followed by heating, grinding, cooling, and optionally agitation; generally cellulase is added after the grinding.

  • Patent number: 5816057
    Abstract: The invention provides a filter for removing liquid from an ice slurry. The filter includes a horizontal filter plate. The ice slurry is passed over the top of the filter plate. The filter includes a first stage where the liquid is removed from the ice slurry, thereby consolidating the ice particles into an ice bed. The liquid is removed by drawing the liquid out of the ice slurry through a set of slots in the filter plate by using a low suction pump. A second stage of the filter draws the remaining liquid entrained in the ice bed through another set of slots using a vacuum pump, which has a higher suction than the low suction pump used in the first stage. A clean water rinse may be sprayed on the ice bed in the second stage to improve the removal of liquid from the ice bed. The filter plate at the second stage may be heated to produce a rinse through the bottom of the ice bed.
