Abstract: The process includes entraining a powder having an average particle size in the range of 1 micron to 1.0 mm in air within a mixing vessel and spraying the entrained powder with a liquid within a spray zone in the mixing vessel. The process is used especially for a throughput rate in the range of 20 to 100 kg/hour of powder. The apparatus for carrying out the process includes a mixing vessel (2) accommodating an axially aligned venturi device (22) and a spray nozzle (18). The mixing vessel (2) may be connected to a vibratory fluidized bed chamber (28) for collecting the sprayed powder.

Abstract: This disclosure relates to a machine for receiving can bodies and automatically outwardly expanding the same to a decorative predetermined contour. The machine includes special transfer means for positioning can bodies on and removing can bodies from supports moving in a convex arcuate path, the transfer device including a turret member mounted for rotation about a fixed axis, a plurality of article carriers pivotally carried by the turret member for movement therewith in a generally circular path, and control means for controlling the contour of a portion of the generally circular path to be coincident with a portion of the arcuate path.

Abstract: This disclosure relates to an apparatus which will unload tubular members, such as cans carried by travelling supports of an endless conveyor at a very high rate. The apparatus includes a plurality of carriers mounted for rotation about a fixed axis and being reciprocable parallel to the axis. The carrier defines a pocket and the pocket cooperates with an outer guide surface to retain the tubular members in position as the carriers rotate about the axis. The apparatus includes access doors which facilitate the inspection of the apparatus and the removal of jams and adjustments for all guide surfaces wherein tubular members of different diameters or lengths may be readily accommodated.

Abstract: A depalletizer apparatus for unloading containers or other articles stacked in tiers which are separated by paperboard upon a pallet. The apparatus has a pallet infeed section, an elevator means for sequentially raising a loaded pallet to a height of one tier and sweep means operated in conjunction with the elevator to remove each tier onto a conveyor. Also disclosed is a pallet discharge means, and a paperboard removal means which together with the sweep means operate to move the pallets, the containers, and the paperboard onto three conveyors for transporting same to three separate collection areas, all conveyors being located adjacent the top of the elevator means. Finally, this specification also discloses a second elevator means for receiving the unloaded pallets and stacking same as well as a compartment for receiving paperboard and collecting same in a manner to facilitate subsequent removal and reuse.
