Abstract:
    A rotary device for dispersing a gas in molten metal comprises a hollow shaft and a hollow rotor fixedly attached to the shaft, with the character that the rotor is hollow and has a plurality of vanes each extending from the shaft towards the periphery of the rotor whereby the hollow interior of the rotor is divided into a plurality of compartments; at least one aperture in the top or bottom of the rotor adjacent the shaft and at least one aperture in the peripheral surface of the rotor such that when the rotor rotates molten metal can enter each of the compartments through the aperture or apertures in the top or bottom, and flow outwardly through the peripheral aperture or apertures to each of said compartments.
