摘要： A compound electrode incorporating a lead substrate utilizes the lead as a support structure. This support structure provides a surface that engages a mesh member, e.g., 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 as 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.

摘要： 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.

摘要： The present invention relates to a new and useful composite fiber. The composite fiber is comprised 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.

摘要： 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. Another option includes depositing electrochemically active material directly onto the concrete, then applying an adherent, electrically conductive overlay such as a titanium metal coating to the treated concrete.
摘要翻译： 典型的阀金属，特别是钛金属涂层的金属涂层通过热喷涂施加到混凝土表面，特别是钢筋混凝土。 诸如钛的金属可以通过几种热喷涂技术中的任何一种喷涂，包括火焰喷涂，电弧喷涂，等离子体喷涂，高速氧燃料喷雾或爆炸枪喷雾。 金属涂层应该紧密地粘附到混凝土上，并且期望地具有孔隙度以便于金属本身的广泛涂覆，并且促进金属可能需要的任何活化。 这种激活可以是电化学活性材料的形式，其允许涂层以电化学活性形式起作用。 一种涂层选择是将溶液施加到喷涂金属上，然后阳极极化金属，以使活性材料沉积在金属上。 另一个选择包括将电化学活性材料直接沉积到混凝土上，然后将粘附的导电覆盖物例如钛金属涂层施加到经处理的混凝土。
