Stephen Rohman 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).

  • Neutralization method using reactive energetic materials
    Patent number: 10828522
    Abstract: Formulations of reactive materials, such as aluminum, magnesium and alloys thereof, with combustible additives such as wood derivatives or charcoal, provide a composition for neutralizing energetic materials via combustion. Specifically, explosive substances such as ammonium nitrate and urea nitrate, which are commonly used as homemade explosives, are rapidly incinerated in a non-propagating manner by the contact with burning reactive material formulations.
    Type: Grant
    Filed: April 23, 2019
    Date of Patent: November 10, 2020
    Assignee: MATSYS INC.
    Inventors: Stephen Rohman, Tony F. Zahrah, Pascal Dubé

  • Compounds useful as chemical precursors in chemical vapor deposition of silicon-based ceramic materials
    Patent number: 5616754
    Abstract: In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of a reactor is coated with a thin layer of a ceramic material, the layer being deposited by thermal decomposition of a non-oxygen containing silicon-nitrogen precursor in the vapor phase, tin an inert or reducing gas atmosphere in order to minimize the formation of oxide ceramics.
    Type: Grant
    Filed: January 26, 1995
    Date of Patent: April 1, 1997
    Assignee: Enichem S.p.A.
    Inventors: Richard Cruse, Veronika Szalai, Terence Clark, Stephen Rohman, Robert Mininni
  • Ceramic vapor deposited coating using a steam-containing carrier gas and non-alkoxy silane precursors
    Patent number: 5424095
    Abstract: In order to reduce the rate of coke formation during the industrial pyrolysis of hydrocarbons, the interior surface of a reactor is coated with a uniform layer of a ceramic material, the layer being deposited by thermal decomposition of a non-alkoxylated organosilicon precursor in the vapor phase, in a steam containing gas atmosphere in order to form oxide ceramics.
    Type: Grant
