Fiona Winterbottom 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).

  • Treatment of gaseous emissions
    Patent number: 7067092
    Abstract: A reactor chamber forms part of an exhaust system of an internal combustion engine. Within the chamber are electrodes between which there is disposed a bed of active material through which, in use, the exhaust gases pass. In the presence of an electrical discharge, driven by an electrical voltage applied across the electrodes, the active material has a catalytic action in the reduction of nitrogenous oxides in the exhaust and also acts to remove hydrocarbons from the exhaust gases.
    Type: Grant
    Filed: October 29, 2003
    Date of Patent: June 27, 2006
    Assignee: Accentus PLC
    Inventors: Stephen Ivor Hall, David Raybone, Fiona Winterbottom, David Leslie Segal, James Timothy Shawcross, Ross Alexander Morgan, Anthony Robert Martin, Michael Inman

  • Corona discharge reactor
    Patent number: 6334982
    Abstract: A corona discharge reactor is for use in processing materials in or carried by a gaseous phase. A plurality of cylindrical individual reactor chambers is provided in an array. The reactor chambers are electrically matched with each other and pulses of electrical energy are supplied under sequential control to each of the individual reactor chambers.

  • Plasma gas processing
    Patent number: 6126779
    Abstract: A plasma enhanced gas reactor including a reaction chamber having a pair of field-enhancing electrodes each of which has an axial passage through it by one of which a reactant gas is admitted to the reaction chamber, and by the other of which reaction products are removed from the reaction chamber.

  • Detection of volatile substances
    Patent number: 6012326
    Abstract: An apparatus for detecting the presence of volatile substances in a gaseous medium, including apparatus for producing within a sensor chamber a localised electric field the energy density of which is sufficient to excite the gaseous medium to a plasma condition, and apparatus for detecting changes in a parameter of the plasma due to the presence of the volatile substances in the gaseous medium.
