The metal coatings include between 0.1 and 20 wt % of aluminum and 0.1 and 10 wt % of magnesium. Layers of magnesium oxide or magnesium hydroxide are formed on outer surfaces of the metal coatings. The layers are altered by applying an acid solution on the outer surfaces of the metal coatings or by applying mechanical forces using a roller leveler, a brushing device, or a shot-blasting device on the outer surfaces of the metal coatings. The metal sheet also includes a layer of oil deposited directly on the outer surfaces of the metal coatings.

Abstract: A method is provided. The method includes providing a steel substrate having two faces coated by dipping the substrate in a bath, altering layers of magnesium oxide or magnesium hydroxide formed on the outer surfaces of the metal coatings by applying mechanical forces, rinsing and drying the outer surfaces, applying a conversion solution on the outer surfaces and painting the outer surfaces of the metal coatings.

Abstract: The invention relates to a method of treating a warm-blooded animal having a solid tumor disease comprising administering a combination which comprises (a) a N-phenyl-2-pyrimidine-amine derivative, especially N-{5-[4-(4-methyl-piperazino-methyl)-benzoylamido]-2-methylphenyl}-4-(3-pyridyl)-2-pyrimidine-amine.

Abstract: Method and apparatus for stabilizing a fire building drum wherein the fire building drum has two ends, is permanently supported at a single cantilever support end, and the remaining end is a free end. The method comprises providing a free end support engaged with the free end to stabilize the tire building drum by restricting lateral movement of the free end; and freeing the free end by temporarily retracting the free end support when desired, e.g., to enable application of annular fire components on the tire building drum, or to enable removal of a built tire from the fire building drum. Preferably, the free end support allows rotation of the fire building drum while the free end support is engaged with the free end. A preferred embodiment uses overtravel of actuator linkages stopped against an extension stop to lock the free end support in place, engaged with the free end, to stabilize the tire building drum without requiring continued power input.

Abstract: Method and apparatus for precision alignment of a moving tire building drum to an automated tire building system working axis, wherein the automated tire building system comprises one or more work stations with application drums aligned to the working axis, and the tire building drum is moved into and out of each work station, comprising: supporting the tire building drum on a rigid, two-sided drum support frame having flat skates with flat bearing rollers under one side, and V-skates with V-mounted bearing rollers under the other side; providing a rail system comprising first and second approximately parallel rails passing through the one or more work stations, wherein the first rail is substantially flat-topped, and the second rail is substantially inverted V-shaped on top; causing the one or more flat skates to ride on the first rail, and causing the one or more V-skates to ride on the second rail; and positioning the drum support frame, the flat skates, and the V-skates relative to the tire building drum
