    摘要： It is described an oxygen dispenser for use in high pressure discharge lamps. The oxygen dispenser of the invention comprises a metallic container capable of retaining solid materials but allowing an easy passage of gas, containing silver oxide. Several possible types of dispenser are proposed. The dispenser has shown capable of avoiding the formation of black deposits coming from hydrocarbons inside the lamps.

    摘要： A method for forming a supported thin layer of non-evaporable getter (NEG) material and a getter device formed thereby are provided. A suspension comprised of non-evaporable getter (NEG) material particles in a dispersing medium is prepared. The NEG material particles in the suspension have a particle size not greater than about 150 .mu.m. The dispersing medium has an aqueous, alcoholic, or hydroalcoholic base and contains not more than about 1 wt % of organic compounds having a boiling temperature of at least about 250.degree. C. The ratio of the weight of the NEG material particles to the weight of the dispersing medium is between about 4:1 and about 1:1. A layer of the suspension is deposited on a carrier by a serigraphic technique. Next, the deposited layer is dried to evaporate volatile components of the dispersing medium and thereby form a dried deposit. Finally, the dried deposit is sintered under vacuum at a temperature between about 800.degree. C. and 1000.degree. C. with a surface of the dried deposit covered with a refractory material to inhibit scaling. Getter devices formed in accordance with this method also are provided.

    摘要： A method is provided for cracking ammonia to produce hydrogen. The method includes the steps of passing ammonia over an ammonia-cracking catalyst which is an alloy including (1) alloys having the general formula Zr.sub.1-x Ti.sub.x M.sub.1 M.sub.2, wherein M.sub.1 and M.sub.2 are selected independently from the group consisting of Cr, Mn, Fe, Co, and Ni, and x is between about 0.0 and about 1.0 inclusive; and between about 20% and about 50% Al by weight. In another aspect, the method of the invention is used to provide methods for operating hydrogen-fueled internal combustion engines and hydrogen fuel cells. In still another aspect, the present invention provides a hydrogen-fueled internal combustion engine and a hydrogen fuel cell including the above-described ammonia-cracking catalyst.
