  • Conical nozzle aerodynamic window
    Patent number: 3949321
    Abstract: An aerodynamic window for isolating different gases or different states of ases when typical transparent window material is not feasible. An adjustable, supersonic conical nozzle is mounted coaxially with an opening and a cylindrical tube is mounted to the opening and extends coaxially toward the conical nozzle. A sliding-wedge-type gate valve is used to close the tube. The start up procedure consists of adjusting the conical nozzle axially to equalize the pressure on both sides of the wedge valve. Once the pressure is equalized the wedge may be removed.
