Abstract: A method and an apparatus for removing foreign particles such as dust from an object of complex shape is disclosed. An object is placed in an enclosed chamber and agitated by mechanical vibration means and by pulsed air jets while rotating, all to separate the dust particles from that object. Periodic injection of compressed air causes the dust particles to be suspended in that air and subsequently removed when the air is aspirated. The method and an apparatus can be used in combination with a household vacuum cleaner for cleaning of large household items such as clothing, pillows, linens, etc. In industrial use, the method of invention can be used for cleaning of electronic components from foreign particles.

Abstract: The present invention provides a cleaner having a hopper for receiving dirty product to be cleaned. The hopper feeds the dirty or contaminated product downwardly onto a cleaning comb that directs the larger sized contaminants onto the exterior surface of a scalping reel having a plurality of apertures of a preselected size and shape. The dirty or contaminated material falls through the screen openings into the interior thereof and on out through the screen at the bottom thereof as it rotates. The dirty or contaminated material is then directed into a vertically oriented aspiration column that has a negative airflow from the bottom thereof upwardly. Fines, chaff, and other light contaminants are carried upwardly by the negative airflow and out of the product, which drops on downwardly into an outlet into a storage facility or onto a conveyor as desired by the cleaner operator. A vacuum nozzle is disposed in close proximity to the scalping reel to remove contaminants that may become lodged in the apertures.

Abstract: Scrap metal chips, which may be oily, wet and dirty and which may be of varying lengths and widths, twisted, curled and cracked, resulting from machining metal articles, are cleaned and dried by passing them sequentially through a washer cylinder, a rinse cylinder and a dryer cylinder. A thread formed of a plate-like metal strip is secured within the interior surface of each cylinder to provide a deep, spiral trough within each cylinder. Each cylinder is rotated so that the chips are moved, in a tumbling motion, along the troughs due to the auger-like thread, from one end to the opposite end. A hot, aqueous washing solution is flowed through the washer cylinder in a direction opposite to the movement of the chips. Similarly, a hot rinse water is flowed through the rinse cylinder in a direction opposite to the movement of the chips therethrough.

Abstract: A system and method for removing drag-out adhering surface treating solutions from barrels and their loads of articles in bulk after electroplating and/or chemical surface treatments and the recovery (recycling) of said solutions.
