Patents by Inventor Allan D. Keras

Allan D. Keras 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).

  • Patent number: 8475723
    Abstract: A Dielectric Barrier Discharge Plasma Generation Cell (DBDPGC) includes a plurality of hot electrodes interspersed with a plurality of ground electrodes whereby a power supply connected between the hot and ground electrodes creates a non-thermal plasma between the electrodes. The hot electrodes are hermetically sealed. A cleaning solution is applied to the electrodes to wash gas stream contaminants and/or reaction by products off the electrodes at times during operation of the cell when desired to clean the electrodes to maintain cell efficiency. A catalyst solution can be applied to the electrodes after cleaning. Where a plurality of cells are electrically connected in parallel, shorts in a cell can be detected by sensing the difference in currents feed to each of the plurality of cells.

  • Patent number: 7767167
    Abstract: A Dielectric Barrier Discharge Plasma Generation Cell includes a plurality of hot electrodes interspersed with a plurality of ground electrodes whereby a power supply connected between the hot and ground electrodes creates a non-thermal plasma between the electrodes. The hot electrodes are hermetically sealed by a rubber material such as a siloxane material surrounding portions of the hot electrodes. The cells are useful in odor removal systems to neutralize odors and VOC emissions in commercial and/or industrial air streams and in gas purification and sterilizing systems which utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and/or reduction of odor causing molecules, VOC's, and other contaminants. Where a plurality of cells are electrically connected in parallel, shorts in a cell can be detected by sensing the difference in currents feed to each of the plurality of cells.

  • Patent number: 6991768
    Abstract: An odor removal system to neutralize odors and VOC emissions in commercial and/or industrial air streams utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and/or reduction of odor causing molecules and VOC's. The ROS is generated by drawing atmospheric and/or odorous air through a Dielectric Barrier Discharge Plasma Generation Cell (DBDPGC). The gas is activated by passing it through the non-thermal plasma field in the DBDPGC, producing the ROS that are then immediately mixed into the odorous gas to be treated. If the odorous gas is passing through the NTP field, it is inherently mixed. When large volumes of gas, and/or extremely high odor loads in large gas volumes must be treated, multiple units can be combined in parallel. The DBDPGC has hermetically sealed hot electrodes and may be used in other applications.
