  • Publication number: 20040115448
    Abstract: A non-chromium based magnesium conversion coating composition for coating magnesium or a magnesium alloy articles, which has as the essential ingredients, an alkali metal permanganate and a PH of 2.5 to 4.0. The composition is effective in protecting magnesium and magnesium alloys articles for more than 200 hours of a neutral salt-fog at 95° F. according to ASTM standard method B-117. When the coated magnesium or a magnesium alloy articles are primed with a paint and the painted articles are exposed to the salt-fog there are show no signs of blistering visible to the naked eye. The process of coating the magnesium or magnesium alloy articles is generally carried out by cleaning the magnesium or magnesium alloy articles with a mild alkaline cleaner followed by treatment in a mild acid solution to remove unwanted metal oxides or hydroxides and then conversion coating with the permanganate salt composition at PH of from 2.5 to 4.0.

  • Publication number: 20010031446
    Abstract: The present invention is concerned with a process for the formation of dental restorations from glass-ceramic materials and the resulting dental restorations. A dental restoration is prepared by placing a glass-ceramic material in a heat-pressure deformable crucible. Heat is applied to the crucible to bring the glass-ceramic to a working range at temperatures above its liquidus temperature. The crucible has heat-pressure deformation properties which are matched to the working temperature of the glass-ceramic. Once the glass-ceramic is heated to its working temperature, the crucible is brought into contract with a mold having a cavity therein. As the distance between the heated crucible and the mold is decreased, the crucible is deformed to form a seal with the mold facilitating the injection of the molten glass-ceramic into the cavity. The resulting dental restoration has superior optical, esthetic and strength properties.

    Abstract: A continuous in-drawing line process and system for drawing stainless steel wire is provided wherein wire is (1) brushed in an inlet brush station to remove oxide film from the wire surface; (2) coated with a lubricant carrier coating which is dried then subsequently cooled; (3) drawn through a drawing machine using a lubricant; and (4) brushed to remove residual carrier compounds from the surface of the drawn wire. The system for carrying out this process includes a wire payoff; an inlet brush station having two pairs of brushes that rotate in a direction opposite to that of the wire to remove oxide film therefrom; a coating device; a dryer; a cooler; a drawing machine; first and second outlet brush stations each having two pairs of brushes that rotate in a direction opposite to that of the wire to remove residual drawing compounds therefrom; and a wire take-up device.
