Abstract: Apparatus and a method for the direct recovery of residual quantities of an aqueous solution adhering to pourable mass parts following an electrolytic and/or chemical surface treatment on the parts, in the course of which the parts are carried in a perforated immersion barrel supported on a movable carriage of a barrel treatment installation. A compressed-air chamber is provided on the carriage, into which the barrel is moved, the chamber being provided with a compressed air source to cause a current of air to flow transversely through the chamber. The compressed-air chamber essentially comprises a horizontal, upwardly cylindrically convex upper half-shell which is fixed on the carriage and which encompasses in a substantially air-tight manner the upper half of the immersion barrel when the barrel has been positioned within the chamber, and a pair of horizontal, lateral, lower, outwardly cylindrically convex quarter-shells which are capable of movement towards and away from one another.
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: A hood with a depending side wall has vacuum passages formed in the inner surface thereof. An inner shroud positioned internally of the hood cooperates therewith in forming the vacuum passages and has a lower edge elevated above the surface to be cleaned. A foramenous skirt depends from the lower edge of the hood sidewall to contact the surface to be cleaned. The vacuum passages are connected to a source of vacuum. A rotating spray assembly inside the shroud sprays cleaning liquid onto the surface to be cleaned.
Abstract: An injection molding compound pellet cleaner 10 removes broken pellets and eliminates excessive dust from molding compound pellets for preparation of the pellets for processing in an automatic molding machine.

Abstract: A portable cleaning apparatus including means for suctioning spent cleaning fluid and recoverable debris, dirt and contaminates from the surface being cleaned, including a portable cart housing a auger type tumbler adapted to received vacuumed debris and wherein the tumbling debris is subject to blast spray cleaning liquids. A recovery chamber at one end of the tumbler provides a closed trap door that retains cleaned debris within the cart until the vacuum suction is disrupted at which time, the trap door is opened, the debris is then deposited, thoroughly cleaned onto the supporting surface.
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.
Abstract: A flatware washer comprising a cogged endless belt mechanism mounted lengthwise in a vertical orientation within a water containment housing; the top end of the cogged belt mechanism being hung around a drive wheel mechanism having complementary cogs mating with the cogs of the belt mechanism; the drive wheel mechanism being mounted at the top of the housing and supporting the belt mechanism in a vertical lengthwise orientation such that a curved bottom end section of the belt mechanism is spaced above the bottom edge of the housing and such that a pair of relatively elongated lengthwise sections of the belt extend downwardly from around the drive wheel mechanism in substantially parallel opposing relationship; the curved bottom end section of the hung belt mechanism being open for receiving a plurality of pieces of flatware between the pair of lengthwise sections; the drive wheel mechanism being connected to a drive mechanism programmed to drivably oscillate the wheel mechanism between predetermined degrees
Abstract: A key deburring and polishing assembly for keys which have been cut on a key machine or for other metal elements which have uneven or hanging pieces remaining thereon has a frame having a base member and a front end plate and a back end plate connected on opposite ends of the base member and a cover which encloses the frame, driving mechanism mounted in the frame and fixedly connected to a cylindrical drum for rotating the same which drum defines a deburring and polishing chamber open at one end and can be aligned for operative association with the inner face of the front end wall so that abrading material which can be charged into the deburring and polishing chamber of the cylindrical drum by a suitable charging opening will not escape therefrom but with sufficient clearance to permit small particles to escape.
Abstract: Cleaning of objects from adhering liquid surface treating medium after galvanic and/or chemical surface treatment and recovery of the liquid medium is performed by lifting objects treated in a working container by a drum aggregate, bringing two half shells over the drum aggregate to embrace the latter so that at only a lower region of the drum aggregate a gap remains, and blowing a gas stream through the half shells to the drum aggregate so that an adhered treating medium is removed from the objects and flows directly back to the working container through the gap.
Abstract: Cleaning apparatus for filled capsules including in combination a rotary drum for tumbling the capsules, napped or tufted fabric liner means for the drum such that uncleaned capsules during tumbling are rubbed by the nap of the fabric and are thereby cleansed of particulate matter, and vacuum means for removing particulate matter from the nap of the fabric; and a process for cleaning filled capsules.
Abstract: An apparatus and a method of cleaning and polishing capsules in which the capsules are blown against one side of an electrically charged screen to clean dust therefrom by their impacting on the screen.
