Abstract: A method for removing exterior material from vials following a serpentine path through various steps of cleaning and drying. The movement of the vials may be limited to a predetermined path formed as an elongated opening in a sheet of material. The sheet may be replaced with a similar sheet with a different width of opening for bottles of differing sizes. The vials are rotated as they move along the path which may be accomplished by slight deviations in the straight sections of the elongated slot such as a zig-zag or sinusoidal wave. Changing the sheet can alter the number of straight path segments and thus the overall path of the vials through the equipment. The cleaning of the vials may include a washing with detergent, water rinsing, and air and vacuum drying. Air is drawn through the paths to produce a completely dry product. Liquid is removed from the vials' bottoms by a vacuum underneath the paths.

Abstract: An apparatus for removing dirt and debris from clumps of down cotton that are released from slots of a group of retrieving belts as the belts pass around a rotating pulley that causes the slots to open includes a first group of approximately semi-circular, parallel tines disposed adjacent to the portions of the belts passing around the pulley. A plurality of fingers extending from the pulley and between the belts into the region bounded by the first group of tines and the belts urges the released clumps slidingly along the tines, and apply forces that loosen dirt and debris, which pass between the tines. The clumps ejected from the upper end of the region are received by pegs of a rotating peg drum and are moved against a second group of approximately semi-circular, parallel tines. The pegs tend to "thump" the cotton clumps as they slide along the second group of tines, further breaking up dried mud and debris therein and causing it to pass outward between the tines of the second group.
