Abstract:
The invention relates to an apparatus and method for the uniform treatment of the surfaces of a plurality of individual parts when such parts are processed as a single heap by introducing a mass of parts into a vessel where they form a heap; introducing a treatment medium into the vessel; repeatedly separating and dispersing the parts from the heap and then returning the parts back into the heap in during controlled cycles so that all surfaces of the parts to be treated are exposed to and contacted by the treatment medium. While the parts are separated and dispersed from the heap, the treatment medium is forced around, through and out from the parts so that, after a number of cycles, all surfaces of the parts are uniformly treated by said treatment medium. The parts move back and forth between a first position in a lower portion of the vessel and a second position above and radially outward from the first position, whereby movement of the parts between the first and second positions enables all surfaces of the parts to be uniformly treated by the treatment medium. The parts treated by this method constitute another embodiment of the invention.
Abstract:
A powdery and granular material treating apparatus wherein a powdery or granular material is contained in a rotary drum and the rotary drum is rotated about a horizontal axis to thereby coat the powdery or granular material. Ventilating perforations are formed on the entire surface or portions of the outer periphery of the rotary drum and drying air is fed to or exhausted from the rotary drum through these ventilating perforations. This powdery and granular material treating apparatus includes: seal plates for sealing drying air fed into the rotary drum; circular sliding frames provided on the sides of the outer periphery of the rotary drum, the outer surfaces of said sliding frames being in sliding contact with the seal plates at portions, through which air is fed to or exhausted from the rotary drum; and partition plates provided on the side of the outer periphery of the rotary drum at positions spaced apart in the circumferential direction of the rotary drum from one another. The rotary drum, sliding frames, partition plates and seal plates are housed in an outer casing.
Abstract:
Apparatus is now provided for the contacting of articles with coating liquid such that there is provided increased through put of coated articles. Articles for coating, such as small metallic parts, are placed in a perforate, rotatable, typically wire basket and most often immersed in a tank containing a coating liquid. During this coating operation, an adjacent basket spaced apart from the first basket is discharging coated parts and subsequently taking on fresh parts for coating at a loading/unloading zone. Following this, and the coating of the parts in the first basket, the baskets are moved in a line, e.g., concurrently. The second basket with the fresh parts is moving to its own coating tank for parts coating while the first basket is moving to the zone for unloading coated parts and for loading of fresh uncoated parts. Thus essentially twice the production of coated parts can be produced in an efficient and economical manner. Furthermore the apparatus readily lends itself to ease in color change for coated parts.
Abstract:
An apparatus for tumbling and cleaning articles such as rocks, clams, potatoes, other vegetables and fruits, and the like. The apparatus has a frame with a container mounted for free rotation thereon. The container has perimetric surfaces with numerous openings therethrough for allowing an impinging jet of water or other liquid to wash the articles and carry dirt away. Fins are advantageously provided about the container for engaging the jet of liquid to thereby rotate the container so that articles being cleaned are tumbled therein. Brushing devices are included within the container to aid in removal of soil from the articles as they tumble against the brushes.
Abstract:
The invention comprises a method and apparatus 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:
The surface treatment is carried out by employing an apparatus comprising a vessel and a holed container rotatably equipped in said vessel.Materials to be treated are filled into said holed container of said apparatus then treating liquids and/or washing liquids are charged in order into said holed container according to the treatment process and said holed container is driven to rotate thus treating liquids and/or washing liquids contact whole surface of said materials and the treatment is carried out. After the treatment, treating liquids and/or washing liquids are effectively removed from the surface of said materials by the centrifugal force accompanying with the rotation of said holed container.
