Abstract: An apparatus for cleaning dust particles from open-ended cans and the like in an automated container filling assembly line. The apparatus utilizes an ionized air injector with a nozzle and a vacuum source having an inlet positioned in close proximity thereto. Both the injector nozzle and the inlet are situated so that the containers can be made to move with their open ends crossing the paths of air flows directed from the nozzle and into the inlet. By means of the injector, an ionized air stream is directed into each empty container to dislodge any dust particles there and to neutralize electrostatic charges causing the particles to adhere to the container walls. Suction, acting through the vacuum source inlet immediately downstream of the ionized air flow, removes any dislodged dust particles before electrostatic charges can build up again between them and the container. The apparatus further includes an enclosure surrounding the injector nozzle and vacuum source inlet.

Abstract: A bottle washer removing bottles from a conveyor, rotating them about 360 degrees, and using paddles of extended length and a stationary guide to replace the bottles on the conveyor. The washer may sit over the conveyor transporting the bottles. The conveyor moves the bottles between paddles which will rotate them through a circle of 360 degrees. At the very end of that arc, however, an obstructing guide rail directs the bottles out of the rotational plane to avoid their colliding with the entering bottles. The paddles that move the bottles about the arc have extensions lying in the direction that the conveyor moves. These extensions control the motion of the bottles as they move out of their plane of rotation so that they will return to the conveyor. The bottle washer, to work at greater length upon the bottles, may in fact move the bottles about two circles of approximately 360 degrees each. As the bottles complete the first rotation, the obstructing guide moves them out of the plane of the first rotation.
