  • Patent number: 7789949
    Abstract: A getter device including a substrate formed of a first getter material having a composition for gettering a first gas species, and a second getter material contacting an external surface of the substrate and having a composition for gettering a second gas species. The substrate has internal porosity connected to openings at its external surface, and the second getter material covers at least a portion of the external surface of the substrate but is absent from at least part of the internal porosity within the substrate so that the first getter material is exposed within the internal porosity for gettering the first gas species. According to a second aspect, a substrate is formed of a material transparent to radiation, and a film of getter material is deposited on the substrate to be sufficiently thin and/or porous so that the film is also transparent to the radiation transmitted through the substrate.

  • Patent number: 7771612
    Abstract: In contrast, the alkaline compound included in the composition of the Document D1 is strong alkali, such as sodium hydroxide. Therefore, the oxide of an alkaline earth metal used in the amended invention is not disclosed or suggested in the D1 at all. In addition, the composition of D1 is an oxygen scavenger and it includes compound which enhance the reaction of oxygen with hydrogen, such as catalyst. Therefore, its hydrogen generating ability is lower than that of the claimed invention.

  • 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.

    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.

In one aspect, a getter composition that includes a getter component and an activator component is provided. The getter component is selected from the group consisting of evaporable and non-evaporable getter materials. The activator component is effective to heat said getter material to a temperature greater than about 500° C. when said activator material is heated to a temperature of between about 280° C. and about 500° C. In some embodiments, the activator component is effective to bring the temperature of the getter material to greater than about 1,000° C. These materials can be used in devices and locations for which low applied activation temperatures are required.
