  • Patent number: 4935115
    Abstract: The invention relates to a method and apparatus for continuously cleaning a long metal substrate, such as a wire, a band, a cord, etc., the long substrate to be cleaned being led through a vacuum chamber, whereinto an inert sputtering gas, such as argon, is fed, and a sufficiently high voltage being maintained between the substrate as cathode and an anode present in the chamber so that an electric discharge takes place between the two electrode, as a result of which the substrate is cleaned by inert gas ions bombarding it during its passage through the vacuum chamber, and the anode being formed by at least one annular electrode, fitted in a long casing of heat-radiation transmitting material and the long substrate being led through the casing in longitudinal direction. The invention further relates to the thus cleaned metal substrates, as well as to the objects of polymer material reinforced therewith.

  • Patent number: 4883722
    Abstract: A brass alloy coating is disclosed which is of use in the manufacture of steel reinforced rubber articles, particularly tires. The alloy contains small amounts of phosphorus, particularly phosphates, and the adhesion between the rubber and brass is thereby improved, especially under high humidity and/or high temperature conditions.

  • Patent number: 4828000
    Abstract: Steel substrate with brass covering layer to enhance adhesion to rubber particularly in humid atmosphere above ambient temperature wherein said covering layer has at its surface a (Cu/Cu+Zn)-ratio of not more than 0.2 the respective Cu and Zn contents being considered in at. %. In addition the content of carbon and inorganic impurities in the brass surface layer is low. A method for producing said brass covered substrate comprises the steps of shortly heating a normal brass covered substrate at between 250.degree. and 350.degree. C. in a vacuum atmosphere.
