  • Patent number: 6998029
    Abstract: Various systems and methods for protecting electrowinning anodes having electrocatalytically active coatings in a bank of electrolytic cells from being damaged by reverse currents. In the first embodiment, one or more auxiliary power sources are provided that, when triggered by one or more predetermined conditions being met, keep the bank of electrolytic cells in an electrical state that is relatively harmless to the anodes having electrocatalytically active coatings. In a second embodiment, the invention is directed to a method of maintaining the polarization of anodes in an electrowinning cell positive of the cathodes (i.e. in a potential region where the anode coating is not susceptible to significant damage). In a final embodiment, the invention is directed to various methods for the installation of replacement anodes and maintenance of electrowinning cells.

  • Patent number: 6352622
    Abstract: A compound electrode incorporating a lead substrate utilizes the lead as a support structure. This support structure provides a surface that engages a valve metal expanded metal mesh. The mesh member has a front and back surface with the back surface facing the lead support structure. At least the front surface of the mesh member is an active surface. Securing of the mesh member to the lead support structure in electrical connection permits the lead support structure to serve as a current distributor for the mesh member. The mesh member may engage the surface of the lead support structure by pressing or rolling the mesh onto the lead. Other engagement means can include the use of fasteners, or welding and the like. The resulting structure can be particularly useful as an electrode assembly for use in an electrolytic cell that serves for the electrowinning of a metal.

  • Patent number: 5952055
    Abstract: A method of protecting reinforced concrete structures comprising of applying a protective cathodic coating containing a non-corroding metal and an electrochemically active material on concrete wherein the protective coating is formed by thermally spraying a mixture of said non-corroding metal such as a valve metal and said electrochemically active material. The coating may also be formed by applying a precursor of the electrochemically active material and a metal-containing layer to concrete, then anodically polarizing said metal layer to convert the precursor into an electrochemically active material.

  • Patent number: 5879817
    Abstract: A metal coating of typically a valve metal, especially a titanium metal coating, is applied by thermal spraying to the surface of concrete, most particularly steel-reinforced concrete. The metal such as titanium may be sprayed by any one of several thermal spraying techniques including flame spray, electric-arc spray, plasma spray, high-velocity oxyfuel spray, or detonation gun spray. The metal coating should be tightly adhered to the concrete and desirably will have a porosity to facilitate extensive coating of the metal itself, as well as facilitate any activation that may be needed for the metal. Such activation can be in the form of an electrochemically active material which allows the coating to function in electrochemically active form. One coating option is to apply a solution onto the spray-applied metal, then polarize the metal anodically to effect deposition of active material on the metal.

  • Patent number: 5387042
    Abstract: A multilingual keyboard system (10) including a customized keyboard unit (12) is provided to operate in conjunction with a central processing unit (14) and a logic system (16) having unique software in order to facilitate multilingual typing from a single keyboard. The keyboard (12) includes customized keys (20) which are shaped to receive label panels (70) on one of several selectable templates (18). Each template (18) corresponds to a particular character set which the user desires to utilize as an alternate character set to that appearing on the key labels (52) on the keyboard (12). The keyboard (12) also includes a keyboard mode toggle key (36) for toggling between a standard mode of operation and the selected alternate mode. The logic system (16) includes software having keymapping schemes associated with each selectable alternate mode. Changing templates (18) permits usage of multiple alternate modes with the same equipment.

  • Patent number: 5192473
    Abstract: A composite fiber is made of non-organic particulates bound to an organic polymer in fiber form. Many non-organic substances are serviceable and valve metal oxides are highly suitable. The organic polymer fiber is advantageously derived from fluorine-containing polymer. The composite fibers can serve as a filter, for instance as a filter-packing material for column chromatography, or can be suitable for separations, e.g., battery separations. The fiber may be compressed, or compressed and sintered, and thereby be useful as bearings or gaskets.

  • Patent number: 4994332
    Abstract: The present invention comprises a closed-loop filter system for continuously removing a metal hydroxide precipitate from an alkali metal hydroxide solution. The filter system comprises a filter having a filter surface and a plurality of small diameter openings in said surface. The alkali metal hydroxide solution is impacted onto said filter surface, metal hydroxide precipitate agglomerating on said surface. The filter surface openings have an average diameter effective for said agglomerating. Means are provided to remove the agglomerated precipitate from said filter surface, and to separate the agglomerated precipitate from the alkali metal hydroxide solution, the agglomerated precipitate having a particle weight to surface area ratio effective for said separation.
