  • Patent number: 4144378
    Abstract: An aluminum coated low alloy low carbon killed steel sheet material which exhibits increased resistance to subsurface oxidation at elevated temperatures having incorporated in the low carbon killed steel before rolling and hot-dip aluminum coating an amount of vanadium or a combination of vanadium and titanium at least four times the weight percent carbon in the steel but not more than ten times the weight percent carbon in said steel with said amount being sufficient to combine with all the carbon and nitrogen in the steel and provide an excess of uncombined vanadium in the steel of about 0.1 wt. %.
    Type: Grant
    Filed: September 2, 1977
    Date of Patent: March 13, 1979
    Assignee: Inland Steel Company

  • Patent number: 4096103
    Abstract: A pressure-sensitive adhesive composition consisting essentially of a natural or synthetic tackifier, an elastomer comprising isoprene and piperylene and a solvent. The elastomer is preferably prepared from certain selected copolymerized C.sub.5 -hydrocarbons from a hydrocarbon mixture containing C.sub.5 -monoolefinic hydrocarbons, C.sub.5 -diolefinic hydrocarbons (cyclic and acyclic), C.sub.5 -paraffins, C.sub.6 -aliphatics, and benzene.The elastomers thus formed, when mixed with certain natural or synthetic tackifiers, have the required tack of pressure-sensitive adhesives.
