Latest Patents
One of his latest patents is the low-pressure mercury vapor discharge lamp. This invention features a vapor pressure-controlling mercury amalgam that is secured to the inner surface of a wall of a container, which has an opening to the discharge vessel. This design minimizes the risk of small portions of the amalgam becoming dislodged due to vibration or shock. The amalgam is secured to the container wall by fusion, utilizing an intermediate 'wetting' agent formed by a thin layer of nickel.
Another significant patent is the barium-aluminum-scandate dispenser cathode. This dispenser cathode consists of a porous metal body with an emissive surface. The pores contain compounds that dispense at least barium and scandium to the emissive surface. The composition includes barium oxide, scandium oxide, and aluminum oxide, with the quantity of scandium oxide being less than 10% by weight. This invention maintains excellent emissive properties comparable to cathodes with higher scandium oxide content.
