  • Patent number: 4459327
    Abstract: A process for manufacturing nuclear radiation shields consisting of neutron-absorbing boron carbide particles embedded in a heat-dissipating copper matrix. Copper is electroplated through a layer of loose, electrically nonconductive boron carbide particles on a metal substrate. The carbide particles may be deposited on the substrate while electroplating, and heat exchanger ductwork may be incorporated. To make cylindrical shields, a cylindrical metal substrate is rotated about its axis giving rise to centrifugal forces which hold the carbide particles on the inner surface and aid electrodeposition. A thermo-mechanical process is described in which boron carbide particles pre-encapsulated with copper are consolidated into a unitary mass on the inner surface of a heated cylindrical substrate with or without the aid of a roller within the cylinder.

  • Patent number: 4352838
    Abstract: Metallic articles, for instance, ferrous strips are metallized, for instance, zinc coated by passing the heated article through a coating chamber and applying thereto a continuous stream of the molten coating metal so as to uniformly and evenly metallize said article. Thereafter, excess molten coating metal is removed from the coated article by hot gas blasting and the hot gas blasted article leaving the coating chamber is immediately cooled. Wiping means may be provided before applying the molten coating metal so as to deflect any molten coating metal dropping from the metallic article passing therethrough, while rollers may be arranged between the coating metal applying means and the hot gas blasting means. Said rollers serve to remove the major part of excess coating metal from the coated metallic article and to stabilize movement of the metallic article passing through the coating chamber.

  • Patent number: 4333775
    Abstract: The invention relates to the depositing of aluminum alloys useful as material for the manufacture of sleeve bearings. Aluminum and lead in the proper ratio are melted in a furnace, transferred to a holding furnace wherein the temperature of the melt is maintained within the molten range, and the melt is directed to an atomizing or nebulizing chamber. According to the invention, the molten material flowing into the atomization chamber is subjected to an atomizing gas flow having a specified angle of incidence to atomize the molten flow of alloy into small particles which are directly deposited on a continuous pure aluminum strip which moves under the atomization chamber at a preset rate, the aluminum strip with the alloy layer is submitted to a rolling operation and thereafter the strip is rolled together with a steel strip, to provide a cladding of the alloy-aluminum onto the steel of the backing and supporting strip.
