  • Hydrodynamic drawing of multiple gauge metal strip
    Patent number: 4015459
    Abstract: Multiple gauge metal strip is prepared by a process which comprises shaping strip material of rectangular cross section to form regions of at least two variable thicknesses defining a stepped surface configuration in at least one of the broad surfaces of said strip, and drawing the shaped strip through a die which defines said cross sectional configuration to produce a reduction of said strip to final dimension, wherein said drawing step is performed without direct surface-to-surface contact between said strip and said die, such that the width dimension of said strip is unchanged and the ratio of strip surface to strip cross sectional area changes by at least 30%. The drawing method of this invention employs hydrodynamic lubrication and can achieve one-pass cross sectional reductions of from 39 to 55%.

  • Process for bonding titanium, tantalum, and alloys thereof
    Patent number: 4011981
    Abstract: A method of bonding film-forming metals and their alloys has been developed. The method comprises applying a first coating of a metal, compound, or alloy of the platinum metal group to the film-forming metal. A second coating of copper is then applied to the first coating. A second metal, such as steel, can then be readily soldered to the copper coating to form a strong, durable bond.This bonding method can be used, for example, to solder a titanium screen or mesh to an electroconductive metal in the assembly of electrolytic cells for the production of chlorine or oxychlorine compounds.
