摘要： An apparatus is provided for the detection of changes in concentrations or amounts of components of a fluid mixture by measuring changes in an electrical or a mechanical property of a sensing element when the sensing element is exposed to the fluid mixture. The preferred property of the sensing element to be measured is its electrical resistance which changes when the sensing element adsorbs at least one component of the fluid mixture.

摘要： The present invention discloses an improved method for filtration of air within enclosed spaces. Improvement is achieved by the use of a high-temperature carbonaceous char that is catalytically active for the removal of certain undesirable constituents from contaminated air under ambient temperature conditions. This carbonaceous char is used as an air filtration medium and incorporated into an air filtration device by any of a number of technologies. Such devices may be used for removal of contaminants such as NOx, NO2, SOx, SO2, H2S, mercaptans, light aliphatic gases such as butane and propane and other compounds such as benzene, hexane, toluene, xylene, amines and the like from enclosed or confined structures such as buildings or vehicles including automobiles, aircraft, trucks, farm equipment, and the like.

摘要： Des agents d'adsorption à base de carbone imprégné et activé destinés à l'élimination de matières toxiques contenues dans des courants gazeux sont utilisés dans une variété d'applications de filtres collecteurs et respiratoires. Les agents d'adsorption à base de carbone imprégné et activé de la présente invention sont efficaces pour éliminer les gaz et/ou vapeurs toxiques dans des applications industrielles et autres et sont exempts de chrome, lequel présente des dangers réels pour la santé. En général ces carbones activés sont constitués d'un agent adsorbant à base de carbone activé et imprégné afin d'obtenir un carbone activé contenant généralement jusqu'à 10 % de molybdène et jusqu'à 10 % de sulfate, de 0 à 20 % de cuivre, de 0 à 20 % de zinc, et selon les caractéristiques souhaitées, complété avec de l'eau ou autrement humidifié. L'ammoniaque aqueux peut être utilisé en tant que solvant de préparation pour l'imprégnation du cuivre, du zinc, du molybdène et/ou du sulfate. Les carbones adsorbants universels de la présente invention se sont révélés efficaces pour éliminer une variété de gaz et/ou vapeurs toxiques et assurent simultanément une protection contre des gaz de types A, B, E et K de la Classification CEN. Les agents spécifiques que les adsorbants à base de carbone activé de la présente invention peuvent effectivement éliminer incluent le chlore, le chlorure d'hydrogène, le cyanure d'hydrogène, le dioxyde de soufre, le sulfure d'hydrogène, le formaldéhyde, le tétrachlorure de carbone, l'ammoniac et autres.

摘要： Impregnated activated carbon adsorbents for the removal of toxic materials from gas streams are used in a variety of respiration and collective filter applications. The impregnated activated carbon adsorbents of the present invention remain effective in removing toxic gases and/or vapors in industrial and other applications, and are free of chromium and its potential health hazards. Generally, these activated carbons are comprised of an activated carbon adsorbent impregnated so as to result in an activated carbon generally containing up to 10 % molybdenum and up to 10 % sulfate, 0 to 20 % copper, 0 to 20 % zinc, optionally supplemented according to the desired characteristics with water or otherwise provided with moisture. Aqueous ammonia may be used as a preparation solvent for impregnating the copper, zinc, molybdenum and/or sulfate. The universal adsorbent carbons of the present invention have been found to be effective for removing a variety of toxic gases and/or vapors, and provide simultaneous protection for CEN Classification gases of Types A, B, E and K. The specific agents that the present invention removes effectively includes chlorine, hydrogen chloride, hydrogen cyanide, sulfur dioxide, hydrogen sulfide, formaldehyde, carbon tetrachloride, ammonia and others.
