  • Method and apparatus for altering the velocity of molecules
    Patent number: 6420699
    Abstract: Apparatus for altering translational velocity of molecules in a gas. A source of gas is in fluid communication with a supersonic nozzle. The nozzle is disposed on an arm at a selected distance from an axis for rotation about the axis. The nozzle has an exit portion substantially perpendicular to the arm. Motive apparatus rotates the arm so that the translational velocity of molecules with respect to a laboratory frame of reference is altered. In a preferred embodiment, gas flows from the source through the axis and the arm to exit from the nozzle.
