  • Patent number: 5643371
    Abstract: A method and apparatus for continuously cladding cast material includes simultaneously roll bonding a cladding liner stock to a material exiting a continuous casting apparatus. At the same time the liner stock is roll bonded to the cast material, the clad cast material is hot worked to form a clad product. A spray shield is positioned near the interface where the liner stock contacts the as cast material to prevent any impurities such as rolling lubricants from contaminating the bonding interface between the liner stock and the surface of the as cast material.
    Type: Grant

  • Patent number: 5197536
    Abstract: A method for making a polymer laminated drag cast aluminum alloy container stock material includes, in a preferred embodiment, drag casting an aluminum alloy suitable for forming into beverage containers into a sheet. The sheet is then cold rolled, at least one of the sheet's surfaces is cleaned and pretreated and a polymer material is laminated thereto. The polymer laminate on the drag cast aluminum alloy surface permits the use of drag cast aluminum alloy sheet material to be utilized, for example, as aluminum beverage container stock material.

  • Patent number: 4327155
    Abstract: Dual coated erosion resistant metal or ceramic structures are provided having an interior adherent indicating metallic or ceramic layer containing a UV sensitive phosphor and an exterior ceramic or metallic protective coating. A method of making such dual coated structures also is provided involving the plasma or flame spraying of blends of particulated metal powder or metal oxide powder and a metal oxide UV sensitive phosphor onto the surface of the metal or ceramic structure.

  • Patent number: 4197145
    Abstract: A small amount of lanthanum and praseodymium will substantially improve the slow strain rate ductility of certain zirconium-base alloys and these new alloys and certain other zirconium-base alloys in the irradiated condition can under certain circumstances have surprising load-carrying capacity and service life. Such other alloys contain yttrium or calcium instead of lanthanum or praseodymium.

  • Patent number: 4178022
    Abstract: Tapered stainless steel spool pieces are welded to the ends of stainless steel pipe lengths at the factory to provide subassemblies which are then annealed and thereafter in the field are positioned with the larger free ends of opposed spool pieces disposed to receive weld metal uniting the subassemblies while coolant liquid is maintained in contact with the inside surfaces of the spool pieces.

  • Patent number: 4049186
    Abstract: The stress corrosion tendency of a welded pipe in service in a nuclear reactor water line is reduced by applying to the outside of the pipe a secondary weld bridging the primary weld of the joint beyond the axial extremities of the primary weld heat affected zone and particularly that part of the zone at the inner surface of the pipe.
