  • Device for the separation of gaseous mixtures into components of different molecular mass
    Patent number: 4108620
    Abstract: A device for the separation of gaseous mixtures into components of differing molecular mass. The device is designed according to the principle underlying a turbine or a turbomolecular pump. The device has a rotor that is equipped with discs made of magnetic material having blades at their periphery and is installed in a stationary casing having a gaseous mixture inlet and at least two gas outlets connected to a gas delivery tube, and to whose inside wall stator discs are attached between the rotor discs. The device further has voltage means. The gas delivery tube has controls connected thereto which keep the total pressure in the gaseous mixture below 10 Pa.
