Abstract: A composition for use in lubricants and function fluids to provide improved anti-shudder and shudder durability properties to an automatic transmission. The composition comprises alkoxylated fatty amines as well as a mixture of other friction modifiers.

Abstract: A chromium-plated steel strip having an excellent weldability and a satisfactory resistance to corrosion, comprises a steel strip substrate, a base layer consisting of an amorphous metallic material, for example, Ni-P or Ni-B alloy, in an amount of 3 to 500 mg/m.sup.2, an intermediate layer consisting of tin in an amount of 2.8 g/m.sup.2 or less, and a surface layer consisting of metallic chromium and hydrated chromium oxide in an amount of 5 to 150 mg/m.sup.2 and 3 to 30 mg/m.sup.2, respectively.

Abstract: A method of and an apparatus for overaging treatment of low melting point-metal plated steel band, in which a hearth roll having surface layer which consists mainly of phenol resin, mineral fiber and small quantity of additive as necessary is used under the overaging treatment temperature range and within weak oxidation, inactive or reducing high temperature gas atmosphere such that the phenol resin substantially does not oxidize and evaporate.The method and apparatus allow overaging treatment of low melting point-metal plated steel band in continuous annealing furnace having many hearth rolls to guide the steel band, and prevent the low melting point metal from being picked up on the surface of the hearth roll.

Abstract: Method for surface treatment of steel sheet which comprises coating the steel sheet with 5- 200 mg/m.sup.2 of a treating solution consisting essentially of at least one member of the group consisting of linseed oil, cottonseed oil, dioctyl sebacate glycol mono-oleate, and glycol di-oleate and a mineral oil, the mineral oil constituting about 0.5- 15% by volume of the solution.
