Patents by Inventor Gert Pfeiffer

Gert Pfeiffer 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: 10150069
    Abstract: A water level sensor device of a fuel filter may include a printed circuit board and a water level sensor composed of electrically conductive plastic. The water level sensor may be coupled to the printed circuit board via an electrically conductive metal element. The metal element may be coupled to the water level sensor via a press-fit assembly. The metal element may include a sharp-edged fastening contour configured to tear open the plastic of the water level sensor when the metal element is pressed against the water level sensor.
    Type: Grant
    Filed: August 9, 2016
    Date of Patent: December 11, 2018
    Assignee: Mahle International GmbH
    Inventors: Daniel Dobernig, Gert Pfeiffer, Werner Schadler, Alfred Weinberger, Peter Zotter

  • Patent number: 5573573
    Abstract: There is disclosed an electric arc furnace for the production of steel by melting scrap, in particular iron scrap, and/or sponge iron and/or pig iron as well as fluxes in a furnace vessel, into which at least one graphite electrode projects, which is displaceable in its longitudinal direction, wherein an electric arc is ignited between the graphite electrode and the charging stock. To achieve a particularly high energy input, the graphite electrode projects into a lower part of the furnace vessel from aside and the lower part, in the region of the graphite electrode, has an enlargement radially protruding outwardly relative to the upper part.
    Type: Grant
