  • Patent number: 5858072
    Abstract: A gas suction filtration apparatus in which a liquid filter medium is contained in a closed container. A gas intake pipe is positioned so as to introduce the gas to be filtered into the bottom of the container and a suction device applies a suction force to the upper part of the container to draw the gas through the liquid filter medium. Gas-liquid mixing plates are disposed in the container which have numerous holes for passage of the gas therethrough. The mixing plates have diameters only slightly smaller than that of the container, and preferably the gap between the outside diameter of the plates and the inside diameter of the container is smaller than the diameter of the holes so that substantially all of the gas to be filtered must pass through the holes to facilitate contact between the gas and the liquid filter medium.

  • Patent number: 5449398
    Abstract: The present invention provides methods for making gases generated in the treatment of hydrogen chloride wastes harmless by neutralization and dissolving, and an apparatus thereof, and a suction-type solution filter container to be used, and providing to shape useful materials or components, such as activated carbon with excellent adsorbability, from the post-treated residues of the wastes. Hydrogen chloride wastes are put in the sealed container 1 and heated at 400.degree. C. or less without oxygen or with air-blocked condition; the gases from the wastes, such as chlorine or hydrogen chloride, are sucked to extract from the container; the extracted gases are introduced into the suction-type solution filter container with liquid filtration agents to pass therethrough; chlorine is removed and reduced in volume from the wastes in the sealed container.

  • Patent number: 5065522
    Abstract: A method of detecting the verticality, a detector therefor and a level maintaining base for a mechanism and an apparatus which employs the above-described detector are disclosed. The method of detecting vertically comprising the steps of: hanging a weight from a reference member disposed along the vertical axis in a state where the weight can be freely swung forwards and rearwards and right and left and in the direction of the intersection on the plane; detecting, in the direction of swinging of the weight, the state where the weight is swung when the weight is freely swung, the state being detected by proper detection means such as electric, magnetic and optical detection means; and analyzing a detection signal denoting the detected direction of the swing, whereby the inclination of the reference member with respect to the vertical axis is detected.
