Patents by Inventor Ernst Rohrer

Ernst Rohrer 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).

  • Device for non-thermal excitation and ionization of vapors and gases
    Patent number: 5483117
    Abstract: The excitation device comprises a plurality of rod-like electrode elements. Each electrode element is enclosed by a chemically and thermally stable protective casing, which can be exposed to high electric fields. The electrode elements are held in vertically extending crosspieces. This results in a setup of several modules, each of which consists of a plurality of electrode elements and two cross pieces. The electrode elements of each module are electrically connected to a conductive bar and have equal potential. Consecutive modules are alternately connected to ground or phase, respectively.

  • Method for the reduction of the chemical oxygen demand of water and waste water by catalytic oxidation and use of such method
    Patent number: 4246105
    Abstract: A method of reducing the chemical oxygen demand or requirement of water and waste water charged with oxidizable substances, by continuous catalytic oxidation. There is used as a promoter excited, dissociated and/or at least partially ionized gases and/or gas mixtures in a quantity such that there are formed a sufficient number of free radicals which initiate the oxidation and also continuously regenerate or reactivate the consumed catalyst. The method is especially useful for producing potable or drinkable water.
