  • Patent number: 8377267
    Abstract: Arrangements for plating a single surface of a thin foil are described. In one aspect, a metal foil is wrapped tightly at least partially around a plating solution drum. The drum is partially immersed in a plating solution such that the waterline of the metal plating solution is below a break point where the metallic foil strip begins to unwind from the plating solution drum. With this arrangement, one side of the metallic foil strip is exposed to the metal plating solution, while the opposing back side of the metallic foil strip does not come in substantial contact with the metal plating solution. In this manner, the exposed side of the foil is plated while the back surface of the foil is not plated. The drum may be rotated to convey the foil through the plating solution.

  • Patent number: 8293080
    Abstract: A conductive contact ring for an electroplating or electrodeposition process on a cylindrical surface includes a frame defining an opening through which the object can be passed and an array of electrically conductive fibers spanning the opening. The frame is electrically conductive and is connected to a DC power source in the process. Two or more contact rings can be used in a process to provide consistent electrical contact with the surface sliding therethrough. A single contact ring can have first and second groups of filaments spaced from each other along the axial length of the surface.

  • Patent number: 8241435
    Abstract: A washing apparatus that easily washes off metal impurities from a porous metal substrate used as an electrode plate core for an alkaline battery. The washing apparatus includes a liquid bath container which holds a solution for washing off the metal impurities. A guide guides movement of the porous metal substrate in the solution held in the liquid bath container. The porous metal substrate is wound into a hoop in a coil-shaped manner, and the guide guides the movement of a sheet portion of the porous metal substrate unwound from the hoop. A winding mechanism winds the sheet portion after being fed through the liquid bath container.

  • Patent number: 8110076
    Abstract: An improved apparatus and method of producing metal foam is provided which involves optimizing the natural convection of electrolyte through a foam being electroplated by inclining the foam during plating. A diagonal flow of electrolyte though the foam enhances electrolyte turnover within the foam while increasing electroplating efficiency. Further increases in plating efficiency are provided by shifting current density from higher plating zones to lower plating zones.

  • Publication number: 20120006691
    Abstract: Conventional electrochemical machining process requires fixed shaped tool cathodes, which makes retooling time consuming and expensive. Flexible tool cathodes include elastically deformable cathodes that can deform in two or three dimensions and can adapt to the contour of the workpiece while the workpiece is moving relative to the flexible tool cathode. That is, the flexible tool cathode can perform tracing. Certain flexible tool cathodes can be also used for special configurations such corners and edges. The flexible tool cathodes can be used to polish, finish, or shape the workpiece through electrochemical processes.

  • Patent number: 8038851
    Abstract: A contacting device for a galvanization apparatus comprises contacting rollers with a continuous rigid external face, which is joined to a jacket section. The jacket section is provided with an inner opening that is wider than a rotating shaft on which the contacting roller sits. This allows the contacting roller to be moved in a radial direction, wherein electric contacting and securing of a basic position is obtained via springs in every one of the radially moved positions. The moveability of the contacting roller ensures good contact as the contacting roller rests against substrates also when the substrates are uneven. The contact pressure can be relatively small.
