Latest Patents

David T Evans holds a patent for "Lamps and discharge devices and materials therefor." This patent focuses on the production of conducting cermets with volume fractions of nickel down to 0.045. The process involves coating relatively coarse refractory oxide granules with fine metal powder particles, followed by compacting and sintering the coated granules. By utilizing oxide granules in the size range of 400 to 800 microns, it is possible to create conducting cermets that have the same volume fraction of metal and thermal expansion coefficients as insulating cermets made from finer granules of the same oxide. These cermets can be used to fabricate tubes and components for electric lamps, including integrally formed conducting and insulating regions.
