Abstract: A mixing device for liquids is described, wherein improved control of the mix is achieved by restructuring the components so that the character of the mix can be observed easily and corrections effected simultaneously. The disperser/mixer incorporates a moveable and rotatable support structure attached to a piston-in-cylinder arrangement. Hydraulic pressure, pneumatic pressure, or a combination thereof in the cylinder is controlled from a unit on the support structure, rather than the base, through a modified piston fixed to the support structure and containing a passageway for hydraulic fluid, rather than through the cylinder.

Abstract: An improved method of extracting titanium from titaniferous materials by reaction with thionyl chloride to form titanium tetrachloride which is separated from the reaction products by volatilization or by extraction.
