Patents by Inventor David M. Stotka

David M. Stotka 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: 8691332
    Abstract: A silver conductive coating possessing infrared absorbing properties is disclosed. The coating is made from a blend of one or more micron size silver powders and/or flakes together with carbon black, inorganic pigment, glass frit, and powdered selenium or bismuth metal. The foregoing dry ingredients are pasted with an organic vehicle, applied to a substrate, and fired at a temperature of up to 1400° F. The coating absorbs infrared radiation beyond the decomposition of carbon black, thus allowing higher firing temperatures and hence shorter firing times.
    Type: Grant
    Filed: October 21, 2010
    Date of Patent: April 8, 2014
    Assignee: Ferro Corporation
    Inventors: Terry J. Brown, David M. Stotka, William G. Picard, George E. Sakoske
  • Patent number: 7955470
    Abstract: A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.

  • Patent number: 6814795
    Abstract: The present invention provides a hot melt conductor paste composition that includes conductive particles and glass particles dispersed in a thermoplastic polymer system. The hot melt conductor paste composition according to the invention is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C. to form a flowable liquid that can be applied to a silicon substrate by screen printing. The hot melt conductor paste composition is particularly suitable for use in the fabrication of photovoltaic cells.
