  • Camouflage material
    Patent number: 5312678
    Abstract: A structure is provided comprising carbonaceous materials for absorbing and/or reflecting radiated energy or electromagnetic energy. The structure is useful for camouflage or for shielding electromagnetic radiation, especially microwaves.
    Type: Grant
    Filed: October 6, 1989
    Date of Patent: May 17, 1994
    Assignee: The Dow Chemical Company
    Inventors: Francis P. McCullough, Jr., Leo R. Novak, David M. Hall
  • Fluorinated non-graphitic carbonaceous films and foams
    Patent number: 4959261
    Abstract: A film or foam structure comprising a non-flammable non-graphitic carbonaceous film or foam having an LOI greater than 40 and at least a partially fluorinated surface.
    Type: Grant
    Filed: July 21, 1989
    Date of Patent: September 25, 1990
    Assignee: The Dow Chemical Company
    Inventors: Francis P. McCullough, Jr., Leo R. Novak
  • Fluorine induced dehydrohalogenation process
    Patent number: 4782121
    Abstract: A process and the product made thereby are disclosed in the preferred form of this process, chlorinated polyethylene is first fluorinated ambient temperature for an interval of contact with elemental fluorine. Then, contact with a strong base converts the polymer into conjugated double bonds, reducing electrical resistance. The double bonds yield a surface layer able to controllably conduct electrical current.
    Type: Grant
    Filed: March 11, 1987
    Date of Patent: November 1, 1988
    Assignee: The Dow Chemical Company
    Inventors: Leo R. Novak, David C. Kelley, Philip Y. Lau

  • Process for preparing olefin oxides
    Patent number: 4634506
    Abstract: An olefin oxide is produced from an olefin in an electrolytic cell by mixing an aqueous electrolyte and liquid olefin under pressure, flowing the liquid mixture through a restricting device into the electrolytic bath of the cell to reduce the pressure of the mixture and to vaporize the olefin, and applying an electric current to the electrolyte/olefin mixture. The electrolyte includes a metal halide, a carbonate salt and a bicarbonate salt.
