Abstract: An aluminum-alloy tab stock, useful for non-detachable tabs having high yield strength and high bending endurance, and a process for manufacture thereof from a heat treatable core aluminum alloy and a non-heat treatable cladding aluminum alloy by arranging the alloys as layers of a composite, bonding the layers by hot-rolling the composite to a thickness reduction of 75-90%, cold-rolling the thinned composite to an additional thickness reduction of 60-70% to form the tab stock, solution heat treating the tab stock and rapidly cooling the tab stock. Optionally, aging to a selected temper may additionally be used.

Abstract: Automotive vehicle bumpers and other articles made of heat-treatable age hardenable aluminum base alloys and having a high spectral reflectance of the order of 95-99% are obtained by applying to the surface of the article which has been previously bright-dipped, an organic solvent solution of a resinous coating composition consisting essentially of (a) a terpolymer of vinyl chloride, vinyl acetate, and maleic acid, and (b) a lower alkyl methacrylate monomer, and curing at a temperature between about 250.degree. and 275.degree.F.

Abstract: An easy-open wall for a container and associated tab is provided and comprises an approximately U-shaped score line in the wall with the score line having a bight and a pair of extensions extending from the bight and having arcuate end lengths terminating in spaced ends. The spaced ends have a portion of the wall therebetween and the score line defines a panel which is completely severable from the wall while remaining attached at the wall portion to define an opening in the wall. The tab is attached substantially flatly against the wall and has a forward portion which overlies the panel adjacent the arcuate end lengths and has a rear portion with the rear portion being easily grasped and lifted to urge the forward portion against the panel to thereby sever the panel first along the arcuate end lengths and then progressively along the extensions and bight to move the panel within the container with the wall portion holding the panel securely to the wall.

Abstract: Apparatus for withdrawing wire in an axial direction from a coil, with rotary counter-twist means which is capable of adjustment during operation to vary the ratio of its speed to that of the wire, and which includes a set of bending rolls with combined straightening and back-tension functions.
