摘要:
A barrel for chemically treating parts having a panel system for retaining said parts within said barrel (10) while permitting passage of a bath solution into said barrel. The panel system comprises a plurality of side panels (202, 202') formed from a continuous sheet of material (200) with integral hinges connecting said panels. The hinges (205) comprise a notch (204) having a center and first and second sides with thickness greater than said center and a material fused to and filling in the notch. The side panels comprise a base and a plurality of perforated sections on the base, with each perforated section containing a plurality of openings in the base for passage of the solution. A plurality of ribs extends outwardly from one surface of the base, wherein the ribs separate each of the perforated sections from an adjacent perforated section. The ribs are comprised of individual rib segments, with each rib segment separating one perforated section from an adjacent perforated section. Each of the rib segements intersect at a point with at least one other rib segment between adjacent perforated sections. At each of the intersection points, at least one rib segment terminates with other rib segments, the terminating rib segment being non-colinearly oriented with respect to other intersecting ribs to provide bracing for another intersecting rib segment. Preferably, three of the rib segments intersect at the intersection point between adjacent perforated panel sections. The perforated panel sections may be rectilinear, circular or hexagonal in shape.

Methods for providing laminated coatings on metal articles using electroplating methods such as barrel plating, vibratory plating, rocker plating or other non-rack methods that involve movement of articles to be plated in a containment apparatus, as well as articles made from such processes. Embodiments of such processes involve mass-transfer modulation to provide compositionally modulated coatings.
摘要:
A container such as a barrel or drum is provided for processing of solid material or parts with a liquid. The container is designed with grooves leading to holes or slots in the side that draw liquid into the container due to the rotation of the container when it is immersed in a tank of liquid. The holes or slots have a small dimension in the direction of rotation to minimize the probability of solid material coming out of the container. The fluid flow caused by the rotation serves to increase the rate of solution replacement inside the container as well as to keep the solid material from falling out through the holes or slots. The container disclosed is useful in processes in the plating, etching, leaching, and surface finishing industries.

摘要:
The invention relates to an electroplating barrel whose barrel shell consists of a plurality of plastic shell elements (11) which are firmly interlinked across the circumference of the shell by gluing or welding without preheating. The shell elements (11) facilitate the production of polygonal barrel shells (10) of different cross-sections. To this end, the shell elements (11) have respective integrally formed rib-shaped projections (16 and 18), whose outer surfaces (21, 22) form between them an angle alpha . The sides of said angle intersect in the barrel axis a-a and the degree of angle is determined, for example, for a maximum number of shell elements (11) that are to be firmly interlinked. The profile of the rib-shaped projections (16, 18) is chosen in such a manner that in the present case the angle alpha can be increased to produce an electroplating barrel from a smaller quantity of shell elements (11) by machining the rib outer surfaces (21, 22).
