Abstract: ABSTRACT OF THE DISCLOSURE      A rear support structure for a cabinet is disclosed. The support structure includes provision for automatically ad-justing the level of the rear of a cabinet to compensate for a supporting surface which slopes from side to side.  The support structure comprises mounting means affixed to the rear, under-side of the cabinet and extending transversely of the cabinet. In a preferred embodiment, a cylindrical roller having an axial bore therein encircles an axle and is rotatable on the axle to facilitate movement of the cabinet.  Either the axle or the bore of the roller or both are arcuate in shape lengthwise of the roller to permit tilting of the roller relative to the axle which in turn permits tilting of the rear of the cabinet with respect to the supporting surface while insuring that the full length of the roller contacts the supporting surface.           In another embodiment, the rear support structure comprises an ellipsoidal member mounted to a channel member affixed to the rear of the cabinet.  A flexible track surrounds the ellipsoidal member and has an arcuate internal surface in engagment with the arcuate outer surface of the ellipsoidal member.  The track is permitted to tilt relative to the channel member and the ellipsoidal member by the arcuate engaging surfaces to compensate for the side-to-side slope of the supporting surface.  The flexible track is movable around the ellipsoidal member to facilitate movement of the cabinet over the supporting surface.

Abstract: ABSTRACT OF THE DISCLOSURE         A waelz process of volatilizing zinc and lead from iron oxide-containing feed material in an inclined rotary kiln, in which pelletized and at least partially dried feed material is charged into the rotary kiln at its upper end together with solid carbonaceous reducing agent, volatil-ization and reduction are effected at a temperature below the softening point of the charge, metallic iron-containing matter is discharged from the lower end of the rotary kiln, part of the discharged matter is separated and is recycled to the feed material before the latter is pelletized, the gaseous oxygen required for combustion is sucked into the lower end of the rotary kiln, and the exhaust gases which contain the volatil-ized constituents are sucked from the upper end of the rotary kiln.  The process of the invention is characterized in that the material to be recycled which has been separated from the metallic iron-containing matter is ground to a particle size below about 1 mm and subsequently admixed to the feed material before the latter is pelletized and the pellets are at least partially dried with oxygen-containing gases at temperatures below 300°C.  The invention permits a relatively low-cost production of pallets which can be used in the waelz process and exhibit only a small tendency to be disintegrated and abraded in the rotary kiln so that a major portion of the solid matter which is discharged from the kiln can be directly used in the blast furnace.
