Abstract: Mixing material around an inner agitator in a mixing vessel is urged upward and outward by rotating the inner agitator in one direction. Simultaneously, mixing material around or adjacent an outer agitator is urged downward and inward by rotating the outer agitator in the opposite direction.

The mixing materials are mashed in the high-pressure region and well mixed in a short time at high efficiency without being agglutinated to the inner agitator.

Abstract: Magnetic brush development apparatus wherein flow of developer material, distributed in balance across the length of the apparatus, is assured. The apparatus includes a sump containing a supply of developer material. A magnetic brush is spaced from the sump. A feed mechanism, located within the housing between the sump portion and the magnetic brush transports developer material from the sump to the magnetic brush. A ribbon blender, located in the sump, agitates and transports developer material to the feed mechanism. The pitch of the blender blades self adjust as a function of developer imbalance. As material builds up, the blades's pitch angles decrease, reducing the rate of material transport toward areas of maximum build up. Thus, for a blender where the desired flow pattern is end-to-end, the end of the other ribbon near the end of the station toward which material is transported by the outer ribbin is self adjusting.
