Patent number: 7090787Abstract: A zeolite and an organic binder are mixed with a solvent to form a paste (302). The paste is then cast or molded (304) into the desired shape. A portion of the solvent is allowed to evaporate from the paste, hardening the getter (306). Getters are often formed in sheets and cut (308) into individual pieces, called dibs, after the sheets have hardened. Even after the getter is hardened, significant amounts of solvent are retained by the getter. The getter is exposed to water vapor which displaces (310) the solvent from the getter. After the solvent is removed, the getter is dried (312) to remove additional water vapor. Because the water vapor does not bind as tightly to the zeolite getter, the water vapor is removed much easier than the solvent. The water may be removed by allowing the getter to dry naturally, or by a vacuum bake process.Type: GrantFiled: August 30, 2003Date of Patent: August 15, 2006Assignee: Texas Instruments IncorporatedInventors: Joshua J. Malone, Simon J. Jacobs

Patent number: 7001535Abstract: This invention describes a solution to the particular problem of liquid water formation in hydrogen getters exposed to quantities of oxygen.

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.Type: GrantFiled: May 10, 2002Date of Patent: February 21, 2006Assignee: Sandia National LaboratoriesInventor: Timothy J.

Patent number: 6506319Abstract: Compositions containing getter material and getter devices for which gettering activity can be activated to applied temperatures that are lower than those temperatures required for activating the getter material alone are disclosed. 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.Type: GrantFiled: August 31, 2000Date of Patent: January 14, 2003Assignee: Saes Getters, S.p.A.Inventors: Alessio Corazza, Claudio Boffito

Patent number: 6426314Abstract: There has been invented a codeposition process for fabricating hydrogen scavengers. First, a &pgr;-bonded allylic organometallic complex is prepared by reacting an allylic transition metal halide with an organic ligand complexed with an alkali metal; and then, in a second step, a vapor of the &pgr;-bonded allylic organometallic complex is combined with the vapor of an acetylenic compound, irradiated with UV light, and codeposited on a substrate.Type: GrantFiled: May 31, 2001Date of Patent: July 30, 2002Assignee: The Regents of the University of CaliforniaInventors: David W. Carroll, Kenneth V. Salazar, Mitchell Trkula, Cynthia W. Sandoval

Patent number: 6398980Abstract: A process is provided for the production of porous non-evaporable getter materials comprising at least one first element selected from Zr and Ti and at least one second element selected from V, Cr, Mn and Ni. The starting metal powders are produced by reduction of the corresponding oxides, with calcium hydride and the thus obtained powders are compacted and sintered at a value of pressure and temperature in a given range. The getter materials due to the production process, have a novel distribution of chemical composition through the getter body, resulting in an improved combination of mechanical and gas-sorption properties.Type: GrantFiled: June 8, 2001Date of Patent: June 4, 2002Assignee: Tovarischestvo S Ogranichennoi Otvetstvennest Ju “Tekhnovak+ ”Inventors: Nina Pavlovna Reutova, Serguej Jurievich Maneghin, Jury Mikhailovic Pustovoit, Vladimir Leonidovich Stoljarov, Vladimir Borisovich Akimenko
