  • NO.sub.x adsorption and removal apparatus
    Patent number: 5635142
    Abstract: The invention discloses a NOx adsorption and removal apparatus employed in the method of passing NOx containing gas into the adsorber 1 filled with NOx adsorbent to adsorb a specific volume of NOx on the adsorbent, passing hot air into the adsorber to desorb NOx, and regenerating the adsorbent, wherein the adsorber is divided in plural zones arranged parallel in the gas flow direction. In this invention, by regenerating after adsorbing NOx in each zone, the regenerating apparatus can be reduced in size, and the energy may be saved by effective utilization of preheat.

  • Adsorbents for removing low-concentration nitrogen oxides
    Patent number: 5612276
    Abstract: The invention provides first to fourth adsorbents for removing low-concention nitrogen oxides. The first adsorbent comprises a carrier of gamma-alumina, and ruthenium supported-thereon. The second adsorbent comprises a carrier of anatase-type titania, and ruthenium supported thereon. The third adsorbent comprises ceramic paper retaining a carrier of anatase-type titania thereon, and ruthenium supported on the ceramic paper. The fourth adsorbent comprises ceramic paper retaining a carrier of anatase-type titania thereon, and a ruthenium halide and a halide of addition metal which are co-supported on the ceramic paper. These adsorbents are free of the influence of moisture and therefore usable without necessitating energy-consuming dehumidification or only with dehumidification on a reduced scale.

  • Telephone network having personal numbers for position-independent
    Patent number: 5251248
    Abstract: This invention allows a subscriber of a telephone network to receive a call by a telephone registered under his/her personal telephone number no matter where he/she carries the telephone with him/her by maintaining a reference table of a personal telephone number assigned to each subscriber, a station number assigned to each telephone, and a subscriber loop address assigned to a telephone connection terminal of the network in a memory within the network.
