摘要： A compound electrode (1) incorporating a lead substrate utilizes the lead as a support structure (5). This support structure (5) provides a surface that engages a mesh member (2), e.g., a valve metal expanded metal mesh. The mesh member (2) has a front (6) and back surface with the back surface facing the lead support structure (5). At least the front surface (10) of the mesh member (2) is an active surface. Securing of the mesh member (2) to the lead support structure (5) in electrical connection permits the lead support structure (5) to serve as a current distributor for the mesh member (2). The mesh member (2) may engage the surface (6) of the lead support structure (5) 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 (3) assembly for use in an electrolytic cell that serves for the electrowinning of a metal.

摘要： A porous product, typically a foam sheet, can be produced by peeling of a foam supply. By peeling the foam supply along its z axis, a product is produced having pores (5) with a uniform pore aspect ratio in the longitudinal direction. Such a porous product, when containing an active filler, can be used as a battery electrode. The electrode can have enhanced electrical and mechanical properties.

摘要： A porous product, typically a metal foam sheet, is produced as a tailored, engineered product. The porous product can have enhancec strength, as well as more desirable electrical and mechanical properties. The product which first exists typically as a flexible, generally polymeric foam sheet in strip (12) form, which strip (12) is produced in the longitudinal direction, is stretched in a direction other than its direction of production. The porous product can have pores which would be anisotropic in form in usual production, which are stretched to at least substantially isotropic form. The product can even be tailored to have pores which are anisotropic in the direction of the stretch. Thus, an engineered product can be produced which, for example, as an open-cell metal foam prepared from a polymeric foam, can have conductivity, both thermal and electrical, as well as strength and ductibility, tailored for greater uniformity and performance.

摘要： Wastewater, particularly black and gray water, produced in macerating human waste, is now treated to provide reduced total suspended solids. The wastewater includes a liquid media comprising salt-containing substance such as brine or seawater. The wastewater is electrolytically treated. In the treatment the electrolysis cell contains an anode that has a surface coating including tin dioxide. During electrolysis, the cell will produce hypochlorite while also reducing BOD and residual chlorine discharge.

摘要： A metal surface is now described having enhanced adhesion of subsequently applied coatings combined with excellent coating service life. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable rough surface characteristic for subsequent coating application. This can be achieved by various operations including etching and melt spray application of metal or ceramic oxide to ensure a roughened surface morphology. Usually in subsequent operations a barrier layer is provided on the surface of enhanced morphology. This may be achieved by operations including heating, as well as including thermal decomposition of a layer precursor. Subsequent coatings provide enhanced lifetime even in the most rugged commercial environments.

摘要： A method and apparatus are disclosed for replenishing metal ions in an electrolyte depleted of the metal ions. A preferred example is replenishing tin in the electrolyte (14) of an electrolytic tinning apparatus having an insoluble anode (16) whereby the electrolyte becomes depleted of tin in the electrotinning process. The replenishment apparatus comprises an electrolytic cell (30) including a tin anode (56), a cathode (58), and an electrolyte chamber for the tin anode and the cathode. The cathode (58) is a gas diffusion electrode. An electrical circuit, usually having additional circuit resistance (92) but free of connection to an external power source, connects the anode to the cathode. The electrolyte chamber is in flow communication with the electrolytic tinning apparatus. The gas diffusion cathode (58) is exposed, on its gas side, to a source of gaseous reactant, eg. oxygen. When the anode and gas-diffusion cathode of the replenishment electrolytic cell are connected together electrically, a current flows between the anode and the cathode, without an external power source. The current flow is at a current density which is effective to dissolve the tin of said tin anode into the electrolyte.

摘要： A coating is now disclosed which is especially serviceable as an improved electrocatalytic coating for an electrode. The coating is a crystalline coating of mixed oxides. The oxides are of iridium, ruthenium and titanium, in very specially defined proportions. When the coating is present on an electrically conductive metal substrate that can serve as an electrode, such electrode has, in combination, the characteristics of reduced oxygen evolution in a membrane cell, low chlorine electrode potentials, plus reduced coating weight loss in a caustic environment.

摘要： A fixed anode structure having at least one broad face utilized in electrodepositing a coating on a moving cathode has a segmented plate anode (3). The plate anode can have a broad face that is generally flat or curvilinear in relation to the shape of the cathode. The anode segment broad faces come together to provide edges (4) that are bias cut in relation to the path of travel of a cathode moving in relation to the anode.

摘要： A platinum black air cathode has an active layer and a support layer. The active layer comprises platinum black plus hydrophobic binder, typically a fluorinated polymer. The support layer may be made up from carbon black bound with a halopolymer binding agent. Such combination can provide for economical utilization of active ingredient without sacrifice of cathode structural integrity. To assist in this structural integrity, a thin support mesh may be used, preferably with the support layer. There can also be employed between the active layer and the support layer a porous bonding layer, which can find broader utilization with layered gas diffusion electrodes in general. For highly desirable, greatly extended operation of the platinum black air cathode, the cathode can be operated intermittently, or anodically polarized or be subjected to infrequent voltage suppression, as well as being involved with any combination of the foregoing.
