    Abstract: Low-pressure mercury vapor discharge lamp having in the discharge vessel a vapor pressure-controlling mercury amalgam which is secured to the inner surface of a wall of a container which is provided with an opening to the discharge vessel. Such securing reduces the risk that small portions of the amalgam might become dislodged by vibration or shock and escape from the container into the discharge vessel. The amalgam is secured to the container wall by fusion thereto by means of an intermediate "wetting" agent formed by a thin layer of nickel.

    Abstract translation: 在放电容器中具有蒸汽压控制汞汞齐的低压汞蒸气放电灯，其被固定在容器的壁的内表面上，该容器的壁设有一个开口到放电容器。 这种固定减少了汞的小部分可能由于振动或冲击而被移动并从容器逸出到放电容器中的风险。 通过借助于由薄层镍形成的中间“润湿剂”将汞合金固定在容器壁上。

    Abstract: An accelerator for charged particles comprising: a vacuum tight chamber, means for producing a beam of particles, and means for inhibiting secondary emission. The means for inhibiting secondary emission comprises outwardly extending wedge-shaped members covering the inner walls of the vacuum chamber. The outwardly facing surfaces of the wedge-shaped members are covered with a nonevaporable getter metal.

    Abstract: A getter device for releasing an evaporable getter metal such as barium in a vacuum tube comprising a ring and a getter metal releasing material attached to the ring. The getter metal releasing material has a zone of high density adjacent to the ring. It also has a zone of low density adjacent to the zone of high density. In getter devices of the present invention, upon release of the getter metal, the getter metal releasing material remains attached to the ring.
