  • Publication number: 20140373558
    Abstract: A cryosorber panel having nanomaterials used for the cryosorption material, with nanomaterial either grown directly on the cryopanel or freestanding nanomaterials attached to the cryopanel mechanically without the use of adhesives. Such nanomaterial cryosorber materials can be used in place of conventional charcoals that are attached to cryosorber panels with special low outgassing, low temperature capable adhesives. Carbon nanotubes and other nanomaterials could serve the same purpose as conventional charcoal cryosorbers, providing a large surface area for cryosorption without the need for adhesive since the nanomaterials can be grown directly on a metallic substrate or mechanically attached. The nanomaterials would be capable of being fully baked by heating above 100° C.

    Abstract: An electron device such as a fluorescent display tube is provided, wherein a simple ring-less getter can be simply fixed and arranged with a large degree of freedom. The ring-less getter is securely fixed to the inner surface of the glass anode substrate using laser beams. The laser beam is irradiated onto the ring-less getter from outside the anode substrate. Thus, the laser beam passes through the anode substrate thus heating and melting the ring-less getter. The corresponding inner surface of the anode substrate is melted through the heating. In cooling, the portion where the ring-less getter and the anode substrate are in a molten state is solidified, so that the ring-less getter is bonded to the anode substrate. The ring-less getter is shaped arbitrarily through press-working a getter material.

  • Patent number: 7397185
    Abstract: In a method for manufacturing an electron tube including a front substrate and a back substrate, a wiring and an electrode are formed on the front substrate and/or the back substrate. A component is mounted on the front substrate and/or the back substrate. A ring-less getter is mounted on at least one of the front substrate, the back substrate and the component. A vessel is assembled and sealed so that the front substrate faces the back substrate. A light is irradiated on the ring-less getter from outside of the sealed vessel, thereby activating the ring-less getter.

  • Patent number: 7238300
    Abstract: A method comprises subjecting ant oxygen scavenger to actinic radiation; and then optionally storing the oxygen scavenger in a container, the container configured such that the oxygen scavenger exhibits no substantial oxygen scavenging activity while inside the container. The dosed oxygen scavenger can later be removed from the container, if stored therein, subjected to a second dose of actinic radiation to trigger the oxygen scavenger, and used in packaging oxygen sensitive products. A stored oxygen scavenger, untriggered, is also disclosed.

  • Patent number: 7001535
    Abstract: This invention describes a solution to the particular problem of liquid water formation in hydrogen getters exposed to quantities of oxygen. Water formation is usually desired because the recombination reaction removes hydrogen without affecting gettering capacity and the oxygen removal reduces the chances for a hydrogen explosion once free oxygen is essentially removed. The present invention describes a getter incorporating a polyacrylate compound that can absorb up to 500% of its own weight in liquid water without significantly affecting its hydrogen gettering/recombination properties, but that also is insensitive to water vapor.

  • Patent number: 6783696
    Abstract: A method for reducing the loss of particles from the surface of porous getter bodies is taught herein. The method consists in producing on the surface of the porous getter a thin layer of a metal or metal alloy with a deposition technique selected among the deposition of materials from arc generated plasma, ionic beam deposition and cathodic deposition. The deposition technique allows for granular or columnar surface of the covering material but still allowing access to the surface of the getter material, resulting in a reduced getter particle loss.

    Abstract: A method for removing oxygen from ammonia at low temperature is described. In one embodiment, oxygen contaminated ammonia is contacted with a getter material that includes iron and manganese that sorbs oxygen to yield ammonia that is substantially oxygen free. In one embodiment, the process of contacting ammonia with the getter material takes place at about 25° C. In another embodiment the weight ratio between iron and manganese is about 7:1. In another embodiment, the getter material is dispersed on an inert support of specific surface greater than 100 m2/g. In one embodiment, impure ammonia is contacted with getter material including iron and manganese that sorbs oxygen and with a drying agent that absorbs water to yield deoxygenated anhydrous ammonia. In yet another embodiment, an apparatus consisting of a gas inlet, gas purification chamber and gas outlet that deoxygenates ammonia when charged with getter material that includes iron and manganese is described.

    Abstract: A method and composition are disclosed for preventing uncontrolled exothermic reaction in the presence of a catalyst. A catalyst deployed as a finely divided powder which is attached to the surface of a low melting point wax or wax-like material which is utilized as a carrier for the catalyst. During operation should the catalyst overheat due to uncontrolled conditions brought about by a run-away reaction the heat of reaction melts the low melting point wax which would itself wet the surface of the catalyst and prevent further catalysis.
