  • Cooled jet blast deflectors for aircraft carrier flight decks
    Patent number: 6575113
    Abstract: Jet blast deflector panels hinged to the deck of an aircraft carrier are pivotally displaced through mechanical actuators to raised angular positions for deflecting exhaust plumes from jet propelled aircraft during take-off to protect closely spaced approaching aircraft which are to take-off thereafter in front of the deflector panels. The underside surface of each deflector panel is formed from a thermal insulating material to provide thermal protection from heating by impinging jet exhaust plumes, and is subsequently cooled by blasts of fluid or air beneath the deck when the deflector panel is in its lowered retracted position.

  • Spinning filter separation system for oil spill clean-up operation
    Patent number: 5800720
    Abstract: Oil spill polluted water is conducted under pressure in sequence through arator devices to collect and burn a polluted water mixture having its oil concentration increased by extraction of water therefrom during axial flow through the separator devices. Such water extraction is effected by sequential radial outflow through oil flow blocking filter walls of the separator devices in response to rotation thereof.
