  • Process of galvanization of tempered steel containing silicon
    Patent number: 4699815
    Abstract: Disclosed herein is an alloy for galvanizing objects of steel which have a concentration of silicon lower than 0.45% by weight. The alloy consists essentially of 0.5 to 1.5% by weight of lead, 0.005 to 0.2% by weight of germanium and the balance zinc. The alloy may further contain 0.001 to 0.05% by weight aluminum.
    Type: Grant
    Filed: December 4, 1986
    Date of Patent: October 13, 1987
    Assignee: Societe Anonyme Dite Societe Miniere et Metallurgique de Penarroya
    Inventors: Jean-Louis Caillerie, Remy Decaens, Armand Limare

  • Process for making non-dusting high lead oxide-low silica additive
    Patent number: 4395291
    Abstract: A lead additive containing a lead oxide and an alkaline silicate which is resistant to dusting, abrasion and segregation. The weight ratio of lead to alkaline silicate, calculated as PbO and SiO.sub.2, respectively, is greater than about 95:5; the moisture content is less than or equal to about 2%; and the density is less than about 5 g/cm.sup.3.The process for producing these additives involve forming a paste of the lead oxide and alkaline silicate, conditioning the paste to form granules and heat treating the granules.

    Inventors: Armand Limare, Bernard Razumowski, Claude Sindezingue
  • Method for producing hydroxylated nickel compounds
    Patent number: 4265718
    Abstract: A method for the production of hydroxylated nickel compounds from a solution of nickelous ions. In the first stage, a solution of nickelous ions is electrolyzed while the catholyte is maintained at a pH from about 1 to 6 and at a temperature of less than about 50.degree. C. In the second stage, the precipitate obtained during the first stage is recovered. The method is applied to the production of highly pure nickel hydroxide.

    Assignee: Societe Metallurgique le Nickel S. L. N.
    Inventors: Armand Limare, Francois Maillot
  • Process for the electrodeposition of ferro-nickel alloys
    Patent number: 4189359
    Abstract: A process of electrodepositing a layer of ferro-nickel alloy using a soluble anode consisting of anodic baskets filled with ferro-nickel shot of a composition substantially identical to that of the layer which it is desired to deposit.
