Hermann Hingmann 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).

  • Grain-oriented magnetic steel sheet comprising an electrically insulating coating
    Patent number: 7169479
    Abstract: The invention relates to a grain-oriented magnetic steel sheet including an electrically insulating coating made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of the sheet. The grain-oriented magnetic steel sheet including the electrically insulating coating made of an amorphous carbon-hydrogen network can be used in transformers.

  • Grain oriented electric sheet of metal with an electrically insulating coating
    Publication number: 20050112377
    Abstract: The invention relates to grain-oriented magnetic steel sheet comprising an electrically insulating coating, made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of sheet, said grain-oriented magnetic steel sheet being used e.g. in transformers. The invention also relates to a method for producing the grain-oriented magnetic steel sheet comprising an electrically insulating coating made of an amorphous carbon-hydrogen network, which method consists of coating of the strip-shaped sheet substrate taking place in a continuous strip method. The application is to be published without a Figure.
