  • Patent number: 11713514
    Abstract: A system for electroplating a web of conductive material with a source material comprises a transport mechanism, an electrical contact, a plating bath, and at least one nozzle. The transport mechanism transports the web through the system. The electrical contact electrically engages the web to cause current to flow into the web. The plating bath contains a volume of an electrically conductive liquid contain ions of the source material. The nozzle is configured to flow a low electrical conductivity fluid onto the web. A portion of the web is immersed in the electrically conductive liquid. The current flowing in the web causes the ions of the source material in the electrically conductive liquid to attach to a surface of the portion of the web.

  • Patent number: 10266959
    Abstract: Golden bronze appearance article, multiple-layer substrate, related methods and uses thereof, particularly for coinage blanks. Methods of producing an article having a golden bronze appearance include annealing a multiple-layer substrate at an annealing temperature for an annealing residence time. The multiple-layer substrate includes a core, contiguous to a copper layer and subsequent tin layer. The annealing temperature and annealing residence time are controlled in accordance with each other for allowing diffusion of the tin layer into the copper layer and producing an annealed substrate comprising an inter-diffused outer bronze layer having a golden appearance. The tin layer thickness is in accordance to the copper layer thickness such that the inter-diffused outer bronze layer has a tin content between about 8% wt. and about 15.8% wt. The core has a sufficiently low content of nickel to reduce or prevent formation of intermetallic compound comprising tin and nickel proximate to the core during annealing.

  • Patent number: 9952272
    Abstract: Systems and fixtures for mounting, under mechanical constraint, wire-like or fiber-like samples of a high aspect ratio and down to 100 micrometers in diameter are disclosed. A region of interest along the length of the sample resides between and beyond a mechanical constraint on either side, allowing access to the region of interest for a wide number of characterization probes. The fixture may provide electrical isolation between two retaining blocks by means of a dielectric support member. The design may achieve minimal thermal expansion along the length of the sample by the material selection for the dielectric support member. Electrical contact may be introduced to the sample through conductive constraints in the retaining blocks. The fixture may have a minimal size perpendicular to the length axis of the sample to facilitate high probe fluxes when a diverging probe is used. The fixture may provide high x-ray transparency between the retaining blocks.

  • Patent number: 6200452
    Abstract: A method and an apparatus for the continuous chromium-plating of elongated members such as bars and the like: the bar to be plated is fed and rotated through at least one tubular shaped chromium-plating anode into which an electrolytic solution suitable for depositing a layer of chromium on the bar, as the latter advances through the said anode, is supplied. The electrolytic solution is supplied into the anode from the bottom upwards, through sets of holes over the bottom and the upper surfaces of the anode; the bottom holes communicate with a pressure balancing and flow distribution chamber for the electrolytic solution. This results in an electrolytic flow upwardly directed in a perpendicular direction to the longitudinal axis of the bar, the temperature of which may be controlled by changing the flow rate of the electrolytic solution circulating inside the anode.

  • Patent number: 5639368
    Abstract: A channelized mass transfer membrane (MTM) is disclosed which has improved ion separation characteristics when employed in electrodialysis cells. The MTM exploits the unexpected ion separation ability of channelized membrane geometries. A major improvement of the disclosed invention is the use of tubular channels formed by means of hollow fibers which limit the directions in which ions can diffuse. The chief embodiments of the MTM exploit either the formation of capillary voids in solid material or the use of hollow fibers to form capillary channels. Additional levels of MTM porosity are achieved by filling of the channels with microporous material. Means are disclosed for cooling the MTM and adaptation of the MTM hydraulic resistance.

  • Patent number: 5132004
    Abstract: A method for the manufacture of a metal-coated steel strip with improved surface structure, wherein the strip is electrolytically coated with one or more metal coatings and the last-applied coating is temporarily melted by supplying heat to the strip (melting-on), is characterized in that the heat supplied to the strip for effecting the melting-on is generated at least in part by an electric current which is at all times non-zero. The heat supplied to effect the melting-on substantially continously compensates heat loss from the strip to the surroundings during the melting-on, and may for example be generated by electrical resistance heating using only a direct current or using an alternating current on which is superimposed a direct current. The strips produced are free of the so-called woodgrain effect.
