Patent ID: 7331540

Claim:
A device for dispersing low-viscosity to high-viscosity mixtures of substances comprising (a) a container comprising an outside wall having an oblong hole, at least one introduction opening for introducing the substances to be dispersed, and at least one discharge opening for discharging the substances following dispersion; (b) a dispersing unit comprising at least one stator and at least one rotor mounted for rotation relative to said at least one stator about an axis of rotation for dispersing the substances that have been introduced into the container; and (c) a displacement device for displacement of said at least one stator within a selected range of movement, said displacement device comprising a double male thread provided on said outside wall and a nut rotatably displaceable along said double male thread, said double male thread having two parallel individual threads spaced from each other so as to form a clearance, said nut covering both individual threads; wherein said at least one stator is mounted for reciprocation toward said axis of rotation, is lockable in an arbitrary position, and is connected to said nut by a pin passing through said oblong hole.
