    摘要: A getter device comprises a getter metal vapor releasing material and a source of an alkali metal which releases an alkali metal during or after the latter period of getter metal evaporation. Such getter devices are found to produce less methane after evaporation of the getter metal without producing higher hydrocarbons. A higher pressure of hydrogen is formed which aids cathode functioning.

    摘要: The present invention discloses metallic fiber boards having catalytic functionality and processes for producing the same. The boards are formed from a mesh of metallic fibers, each fiber having a first layer of an oxide and a second layer of a porous oxide. A catalyst, either disposed on the surface of the second layer, or dispersed within the second layer, provides catalytic functionality to the fiber board. The first layer is produced by thermal oxidation of the metallic fibers, while the second layer and catalyst are produced by thermal decomposition of precursor materials applied to the fiber board while in solution, typically as a spray of atomized droplets. The resulting boards are used to catalyze the combustion of hydrocarbons, especially methane, and particularly in household boilers.

    摘要: A process for producing a field emitter flat display includes providing a supported porous layer of a non-evaporable getter material by depositing the non-evaporable getter material on a substrate followed by sintering the deposited material. The substrate having the porous layer of non-evaporable getter material thereon is then housed in an inner space defined by opposing plates. The inner space is then evacuated and hermetically sealed. The non-evaporable getter material is preferably deposited by preparing a suspension of non-evaporable getter material particles in a suspending medium, coating a surface of a substrate with the suspension by, e.g., spraying, and sintering the coating.

    摘要: The process of the present invention provides for the sorption of residual gas in a vessel by means of a non-activated, non-evaporated barium getter. It comprises the steps of reducing an alloy of Ba.sub.z +(Ba.sub.1-x A.sub.x).sub.n B.sub.m to a particle size of less than 5 mm, under vacuum or an inert gas atmosphere and then placing the particulate alloy in the vessel. Upon exposing the particulate alloy to the residual gas in the vessel at room temperature the gas is sorbed. The metal A is a metal selected from the group consisting of elements of Group IIa of the periodic table of elements, excluding barium. The metal B is selected from the group consisting of elements of Group Ib, IIb, IIIa, IVa and Va of the periodic table of elements. Furthermore n=1, 2, 3 or 4 and m=1, 2 or 5, whereas o.ltoreq..times..ltoreq.0.5 and z is a value from zero to such a value that the total barium in the alloy is less than 95% by weight of the alloy.
