Patents by Inventor Henry G. Lankenau

Henry G. Lankenau 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).

  • Liquid concentration apparatus
    Patent number: 4364794
    Abstract: An evaporator for increasing the solids content of a liquid-solids mixture employs vapor compressor means to recycle superheated vapors that are boiled off the mixture by a heat transfer fluid. The superheated vapors are forced into the mixture before the mixture is heated by passage over a heat transfer surface, and the vapors cause the mixture to flow past such heat transfer surface at sufficient velocity to prevent excessive solids from depositing on the heat transfer surface.
    Type: Grant
    Filed: November 20, 1980
    Date of Patent: December 21, 1982
    Assignee: Ecodyne Corporation
    Inventor: Henry G. Lankenau
