  • Oxidizing additives for control of particulate emissions
    Patent number: 6797035
    Abstract: The present invention discloses a process for removing undesired particles from a gas stream including the steps of contacting an additive containing nitrate and/or nitrite anions with the gas stream; collecting the undesired particles and additive on a collection surface to form an aggregate on the collection surface comprising the additive and undesired particles; and removing the agglomerate from the collection zone. The anions can be compounded with one or more of potassium, sodium, calcium, and aluminum. In a preferred composition, the anion(s) is/are compounded with potassium. The process may be applied to electrostatic precipitators to improve undesired particle collection efficiency.

  • Modified container using inner bag
    Patent number: 6092272
    Abstract: In accordance with the present invention, in an aircraft storage container which is used for the transport of cargo items, defines an enclosed interior compartment and includes a hatch for selectively accessing the interior compartment, there is provided an improvement of the aircraft storage container. The improvement is provided with a high strength flexible bag member disposed about a substantial portion of the interior compartment for distributing force in response to explosive forces emanating from cargo items within the bag member. The bag member includes an opening and is positionable within the interior compartment such that the opening is adjacent the hatch for allowing cargo items to be placed into and removed from within the bag member via the hatch and the opening. The improvement is further provided with a bag opening frame which is attachable to the opening of the bag member and formed to receive cargo items for storage within the bag member therethrough.
