Patents by Inventor Isabella V. Mayer

Isabella V. Mayer 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).

  • Method for depositing thin layers of a material consisting of chemical compounds comprising a metal from group IV of the periodic system, nitrogen and oxygen onto heatable substrates
    Patent number: 5776556
    Abstract: The invention concerns process for producing thin layers of a material containing chemical compounds between a metal from group IV A of the periodic system, nitrogen and oxygen. The optical and electrical properties of this material can be set within wide limits by means of small voids, without the need to alter the chemical composition. The material is suitable in particular for use as a selective radiation converter in the solar energy and power industry. Aside from other processes for its manufacture, it can be produced as a thin coating deposited on a substrate by means of reactive evaporation.
    Type: Grant
