  • Gas purifier having rechargeable adsorber filter with removeable rechargeable sample canister
    Patent number: 4135896
    Abstract: A gas purifier having a removeable sample canister apparatus and gas adsorber in combination is provided for use in atmospheric containment and cleanup systems in nuclear power plants and other air and gas filtering applications. The sample canister is particularly adapted for removeable attachment to and use in combination with a gas adsorber having a plurality of parallel spaced filter beds. The sample canister is designed to permit the sampling of adsorbent material at discrete time intervals without disturbing adsorbent material in the filter beds and without disturbing the structural integrity of the gas adsorber to which the sample canister is attached.

  • Methods for removing radioactive isotopes from contaminated streams
    Patent number: 4133651
    Abstract: Methods for removing radioactive isotopes from contaminated gas streams for use in atmospheric containment and cleanup systems in nuclear power plants are provided. The methods provide for removal of radioactive isotopes from a first portion of the contaminated stream, separated from the remaining portion of the stream, so that adsorbent used to purify the first portion of the contaminated stream by adsorption of the radioactive isotopes therefrom can be tested to determine the adsorbing efficacy of the generally larger portion of adsorbent used to purify the remaining portion of the stream.
