  • Regeneration of whetlerite for adsorbing toxic pollutants from air
    Patent number: 5162274
    Abstract: Whetlerite degraded by exposure to atmospheric contaminants is treated to restore its ability to adsorb toxic air pollutants by passing through it a flow of an oxygen-containing gas further containing from 500 to 2000 ppm of carbon monoxide and water vapor corresponding to 60 to 90 percent relative humidity at 60 to 80 degrees C.
    Type: Grant
    Filed: December 13, 1990
    Date of Patent: November 10, 1992
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventor: Victor R. Deitz
  • Protecting military targets against weapons having IR detectors
    Patent number: 4756778
    Abstract: Pyrolyzed carbon fibers are intercalated with alkali metal by contacting fibers with hot metal vapors at a specified temperature to produce an infrared emissive chaff. This chaff can be released into the air to produce a heat generating cloud, which can serve as an infrared decoy or screen to protect military targets against weapons having infrared detectors. The chaff gives off a longer lasting, more moderate heat supply due to the intercalation of its active element, and is much easier to store and handle than prior art pyrophorics.
    Type: Grant
    Filed: December 4, 1980
    Date of Patent: July 12, 1988

    Inventors: Victor R. Deitz, Joseph P. Reardon, Neldon L. Jarvis
  • Chemically impregnated in situ regeneration of the efficiency of activated carbon filters for trapping radioactive iodine
    Patent number: 4695561
    Abstract: A compound for chemically impregnating an activated charcoal bed for efficiently removing radioactive iodine from air flow from an area through a chemically impregnated carbon filter in a nuclear air cleaning system in which the compound is selected from Quinuclidine.CH.sub.3 I; Triethylenediamine.2CH.sub.3 I; and Hexamethylenetetramine.CH.sub.3 I.
    Type: Grant

    Date of Patent: September 22, 1987
    Inventor: Victor R. Deitz
  • In situ regeneration of the efficiency of activated carbon filters for trapping radioactive iodine
    Patent number: 4518562
    Abstract: A method of regenerating a nuclear-grade activated carbon filter, used to trap radioactive iodine, is accomplished by introducing suitable airborne chemical reducing agents into the air flow.

  • Activation of water soluble amines by halogens for trapping methyl radioactive iodine from air streams
    Patent number: 4040802
    Abstract: Gas adsorbent charcoals impregnated with an aqueous solution of the reaction product of a tertiary amine and elemental iodine or bromine are better than 99 per cent efficient in trapping methyl iodine.sup.131. The chemical addition of iodine or bromine to the tertiary amine molecule increases the efficiency of the impregnated charcoal as a trapping agent, and in conjunction with the high flash point of the tertiary amine raises the ignition temperature of the impregnated charcoal.

  • Salts of the iodine oxyacids in the impregnation of adsorbent charcoal for trapping radioactive methyliodide
    Patent number: 4016242
    Abstract: Radioactive iodine and radioactive methyliodide can be more than 99.7 per cent removed from the air stream of a nuclear reactor by passing the air stream through a 2-inch thick filter which is made up of impregnated charcoal prepared by contacting the charcoal with a solution containing KOH, iodine or an iodide, and an oxyacid, followed by contacting with a solution containing a tertiary amine.

  • Enhancement of ultimate tensile strength of carbon fibers
    Patent number: 3931392
    Abstract: A method of enhancing the tensile strength of carbon fibers of laboratory d commercial materials. Carbon fibers are immersed at ambient temperatures in liquid bromine or bromine dissolved in a solvent within a chemical resistant container for a period of time, the bromine is then removed by flushing with an inert gas. The removed bromine may be recovered and reused by condensing the vapor; small traces of bromine may remain within the fiber. It has been found that the bromine treatment enhances the tensile strength of the treated fiber.
