Pickling Apparatus U.S. Patent 5,579,788. Dec. 3, 1996 W. Ammermann et al., assignors to Sundwiger Eisenhuffe Maschinenfabrick GmbH & Co., Hemer, Gemany

An apparatus for the surface treatment of material with a treatment liquid, com- prising a vessel through which the mate- rial to be treated is to be conveyed, the vessel having sidewalls, a bottom, a clos- able lid, and an inner space, an inlet opening and an outlet opening through which material is introduced into and exits from the vessel, and at least a first shut-off partition in the region of the inlet opening and at least a second shut-off partition in the region of the outlet open- ing, wherein each of the shut-off parti-

tions includes a bloating body, which rests on the surface of the treatment liq- uid.

Apparatus for Surface Polishing U.S. Patent 5,580,300. Dec. 3, 1996 K. Tsufsumi, Kyofo, Japan

A method for treating a surface of an object with a medium composed of treat- ing liquid and a granular substance, com- prising placing treating liquid and a gran- ular substance in a treatment barrel, placing at least one object to be treated bigger than the particles of the granular substance in the barrel in such a way that the object is submerged under the treat- ing liquid, starting rotation of the barrel in one direction, mechanically stopping the rotation of the barrel, restarting rota- tion in the reverse direction, mechani- cally stopping the rotation of the barrel, and repeating so as to partially rotate the barrel in reciprocating motion at a con- stant velocity for a time sufficient to treat the surface of the object.
