Clifford G. Shultz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of and system for treating mixed radioactive and hazardous wastes
    Patent number: 5640702
    Abstract: There is disclosed an improved method and system for the selective treatment and volume reduction of mixtures of gaseous, liquid and solid contaminated waste materials. The contaminated waste materials include mixtures of hazardous and/or radioactive wastes which react with selected active reducing metals in liquid form, preferably aluminum.
    Type: Grant
    Filed: September 1, 1994
    Date of Patent: June 17, 1997
    Inventor: Clifford G. Shultz
  • Destruction of inorganic hazardous wastes
    Patent number: 4695447
    Abstract: Hazardous waste containing inorganic compounds which contain heavy metals or particular hazardous anionic groups or which are hazardous halides or non-metal oxides or sulfides is contacted with molten aluminum to provide reduction to lower less hazardous oxidation state.
    Type: Grant
    Filed: December 17, 1985
    Date of Patent: September 22, 1987
    Assignee: Detox International Corporation
    Inventor: Clifford G. Shultz
  • Destruction of nerve gases and other cholinesterase inhibitors by molten metal reduction
    Patent number: 4666696
    Abstract: Cholinesterase inhibiting agents such as nerve gas agents and pesticide agents are destroyed by reaction with molten aluminum and the gaseous products are analyzed and recycled if they are not essentially free of such agents.
    Type: Grant
    Filed: March 29, 1985
    Date of Patent: May 19, 1987
    Assignee: Detox International Corporation
    Inventor: Clifford G. Shultz
  • Process for the thermal and chemical destruction of toxic and infectious biological materials
    Patent number: 4599141
    Abstract: A process for the destruction of biological waste products comprises the steps of heating said waste products in a sealed chamber, e.g. at 600.degree. C.-850.degree. C., to volatize volatiles and to pyrolyze non-voltatiles and producing an output stream comprising gas with residual biological matter entrained therein followed by treating said output stream with molten aluminum thereby effecting chemical reduction by reaction with the aluminum and producing innocuous effluent.
    Type: Grant
    Filed: August 7, 1984
    Date of Patent: July 8, 1986
    Inventor: Clifford G. Shultz
  • Destruction of organic hazardous wastes
    Patent number: 4552667
    Abstract: Hazardous waste containing organic compound having covalently bound oxygen, nitrogen, sulfur and/or phosphorus is reduced with aluminum to less hazardous form.
    Type: Grant
    Filed: June 25, 1984
    Date of Patent: November 12, 1985
    Inventor: Clifford G. Shultz
  • Destruction of polychlorinated biphenyls and other hazardous halogenated hydrocarbons
    Patent number: 4469661
    Abstract: This invention relates to the destruction of polychlorinated biphenyls (PCBs) and other hazardous halogenated hydrocarbons by treating solids contaminated with such to extract the halogenated hydrocarbon, vaporizing extract and contacting the vapor with a bath containing molten metallic aluminum.
    Type: Grant
