  • Patent number: 10370769
    Abstract: In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.

  • Patent number: 7807028
    Abstract: There is provided a substantially permanent stainless steel cathode plate suitable for use in electrorefining of metal cathodes, the cathode being composed of a low-nickel duplex steel or a lower grade “304” steel, wherein operational adherence of an electrodeposition thereon is enabled by altering various qualities of the cathode surface. There is also provided a method of producing the above duplex or Grade 304 cathode plates, such that the desired operational adherence of the deposit upon the plate is not so strong as to prevent the deposit being removed during subsequent handling.

  • Patent number: 7504009
    Abstract: The invention relates to a method for achieving a good contact surface on an aluminium electrode support bar used in electrolysis. In the method the support bar is fabricated as a continuous bar and a highly electroconductive layer is formed on its end. The highly electroconductive layer forms a metallic bond with the support bar and can be achieved for example with thermal spray coating. The invention also relates to an electrode support bar, the end of which is coated with a highly electroconductive material.

  • Patent number: 7479209
    Abstract: Production of pure metals through electro-winning and electro-deposition is accomplished by electrolytic deposition of metal over a reusable stainless-steel plate (cathode). Metal is deposited on both faces of the cathode, as well as on its edges, creating problems when removing the deposited metal. Breaking the deposited edges to remove the metal deposited on both faces produces irregular edges, folding and damages to the surface of the cathode, requiring re-processing, increasing costs of the deposited metal, as well as repairs or replacement of the cathodes. This invention includes a structure made of insulating material to which are fixed electrically energizable cathode guidance profiles with a cross-section similar to an omega and which house the edges of the cathodes, holding them in position during the process.

  • Patent number: 7470351
    Abstract: A system for producing metal particles using a discrete particle electrolyzer cathode, a discrete particle electrolyzer cathode, and methods for manufacturing the cathode. The cathode has a plurality of active zones on a surface thereof at least partially immersed in a reaction solution. The active zones are spaced from one another by between about 0.1 mm and about 10 mm, and each has a surface area no less than about 0.02 square mm. The cathode is spaced from an anode also at least partially immersed in the reaction solution. A voltage potential is applied between the anode and cathode. Metal particles form on the active zones of the cathode. The particles may be dislodged from the cathode after they have achieved a desired size. The geometry and composition of the active zones are specified to promote the growth of high quality particles suitable for use in metal/air fuel cells. Cathodes may be formed from bundled wire, machined metal, chemical etching, or chemical vapor deposition techniques.

  • Patent number: 7425257
    Abstract: The disclosure relates to a method of obtaining a good current contact on the support bar of a cathode used in electrolysis. In this method a highly electroconductive layer is formed on the contact piece on the end of the support bar of the cathode, especially at the point that comes into contact with the electrolysis cell busbar. The electroconductive layer forms a metallic bond with the contact piece of the support bar. The disclosure also relates to the cathode support bar, wherein a highly electroconductive layer is formed to the contact piece on the end of said bar, in particular the area that touches the electrolysis cell busbar.

  • Patent number: RE46212
    Abstract: Cathode plate edge protector systems formed by secondary and tertiary molding processes, in which fluid plastic is molded around and/or introduced into previously manufactured plastic edge protectors. A U-shaped edge protector system is formed by bevel-cutting abutting ends of edge protector strips, securing the strips in the desired configuration a molding jig, and molding corner pieces around the abutting ends. The system is then removed from the jig and slip-installed over the two sides and the bottom edge of a cathode plate. In an optional tertiary molding process, fluid plastic may be introduced into the remaining void between the edge protector system and the cathode plate. Another edge protector system is formed by mounting edge protector strips on opposing side edges of a cathode plate, damming the open ends, and introducing fluid plastic in the contained voids between the strips and the cathode plate.
