Abstract:
An article handling apparatus including a holder into which an article can be lowered and from which it can be lifted and which can rotate the article about a substantially horizontal axis, the article including a projection on at least one side of the article, the holder including a member rotatable about the axis and having a radially outwardly open channel for receiving the projection when the article is lowered into position, in the channel in response to a predetermined rotary movement of the member and the article away from the loading and unloading position such that the article is securely held during rotation. The preferred use is for holding baskets of impregnated castings in an enclosure for draining, cold water washing or hot water curing.
Abstract:
There is disclosed an article treating apparatus particularly apparatus for pressure-impregnating or vacuum impregnating porous articles such as metal castings. A holder for the articles or a metal basket containing them is disposed in an autoclave and can be rotated about a horizontal axis. It has a horizontal through-passageway so that articles to be treated can be simultaneously loaded at one end of the passageway and unloaded at the other end of the passageway by an indexing mechanism. The indexing mechanism has a plurality of pusher arms which can be moved laterally into the path of the articles and then moved horizontally to push the articles along rails into and out of the passageway. The holder is stopped at a predetermined rotary position in which a longitudinal slot is opposite the pusher arms so that unloading and loading may be effected simultaneously with a single movement of the indexing mechanism, a pusher arm passing completely through the slot. The lower part of the pressure vessel contains liquid impregnant and the holder can be rocked between an upper loading and unloading (and spin) position and a lower immersed position.
Abstract:
Coating device whose coating vessel is driven simultaneously with a rotary motion on itself around an axis of rotation and with a planetary motion around this axis of rotation. The device makes it possible to coat various products, especially kernels, seed, fruit, confectionery products, dragees, sweets, pharmaceutical products, and the like.
Abstract:
A barrel-type coating apparatus includes a perforated barrel rotatably and pivotably mounted on a frame, and a cup-shaped heating chamber slidably supported on the frame and reciprocably movable toward and away from the barrel for removably receiving therein the barrel from an open end thereof while the barrel is held in an upwardly tilted position. The cup-shaped heating chamber includes a heater mounted thereon for heating the atmosphere in the heating chamber and a paint-spraying nozzle projecting into the interior of the heating chamber. With this construction, the barrel atmosphere is heated and cooled immediately after the barrel has been received in and removed from the hot atmosphere in the preheated heating chamber so that the paint-spraying, setting, baking and cooling steps can be carried out at a relatively short period of time. An open end of the heating chamber is directed vertically downwardly while the heating chamber is held in an elevated waiting position remote from the barrel, thereby preventing the hot atmosphere in the heating chamber from escaping from the heating chamber.
Abstract:
A drum rotating about a horizontal axis, designed to coat dragee pellets or other granules with a hardenable substance, has a polygonal--preferably nine-sided--peripheral wall and corresponding frustopyramidal end walls. The peripheral wall consists of angularly adjoining panels and has an access aperture extending partly over two such panels, this aperture being sealable by a gabled flap hinged to the drum at its trailing edge and adapted to be locked in a closed position by a sliding bolt coacting with a latching cylinder and an unlatching cylinder in a certain angular position of the drum whereby the unlatched flap will swing open on leaving that position and will swing closed on reapproaching it. Each panel is provided with a longitudinally extending grid, formed by a perforated sheet-metal strip, through which drying air is admitted from below into a granule bed; part of this air passes through slantingly disposed inwardly projecting perforated baffles which stir the granules and deflect them toward a transverse midplane of the drum where accompanying detritus can escape through the grids to the outside.
Abstract:
In a rotary drum spray grainer there is provided a deflector plate overlying the spraying nozzles in the spraying zone to provide a drying zone where spray grained particles fall in a substantially uninterrupted downward path through the drying gas.
Abstract:
The invention comprises a method for providing a coating to objects such as a lens. A bath of coating solution is provided and the objects are immersed into the solution and removed from the solution at a constantly changing speed. The speed of removal is slower at the top and bottom of the object and faster at the midpoint of the object. Thus the coating is thinner at the top and bottom and thicker at the center (where greater abrasion resistence is required). The slower speed at the removal of the bottom edge of the lens from the solution provides a thin coating and eliminates the formation of coating drip lines and puddles.
Abstract:
An apparatus is disclosed for subjecting articles to a forceful air stream while confined within a tumbling barrel having a perforated peripheral wall. The apparatus comprises pivotally connected shroud members that are adapted to sealingly enclose the barrel, but to leave uncovered a bottom longitudinal portion of the perforated wall. Air is blown into the shroud members about the barrel and flows into the barrel through the perforated wall and thereafter out the barrel through the uncovered wall portion, thereby forcefully flowing over the confined articles to dislodge solution clinging thereto.
Abstract:
An apparatus for coating pills, tablets, capsules, and the like, comprising a continuous conveyor belt means disposed about and supported by at least three rollers. The upper surface of said conveyor belt means forms a concave region sufficiently large to retain and tumble the objects being coated while the conveyor moves in an inclined path around said rollers. At the sides of the concave region of said conveyor belt means in which the tablets or pills tumble in a bed during operation, there is provided side retainer plates to prevent loss of material under treatment in a lateral direction to the direction of the conveyor belt drive. The concave depth of the conveyor belt may be changed by altering the distance between the rollers forming either the base or the heighth of the triangle with screw means attached to said rollers and co-operatively engaged with screw threads in the apparatus support frame. Discharge of the pills from the tumbling belt coater is effected by pivoting the entire assembly in the direction of conveyor belt travel about the axis of the base roller.

1. A PROCESS FOR SOFTENING FRESHLY WASHED FABRICS IN AN AUTOMATIC ROTARY DRUM CLOTHES DYER COMPRISING THE STEPS OF (A) ADDING TO THE DYER SAID FABRICS AND A PREMEASURED LENGTH OR SHEET OF A SOFTENING COMPOSITION CONSISTING ESSENTIALLY OF A FABRIC SOFTENER IMPREGNATED INTO AN ABSORBENT SUBSTRTE HAVING AN ABSORBENT CAPACITY OF FROM 5.5 TO 12; WHEREIN (I) SAID FABRIC SOFTENER HAS A SOFTENING POINT OF FROM 100*F.
