Abstract: An apparatus for controlling metal coatings on wire, strip, mesh or the like, emerging substantially vertically from metal baths, comprising an electromagnetic device adapted for situation at or below the point of emergence of the wire, strip, mesh or the like from the molten bath, said electromagnetic device providing an alternating electromagnetic field generated by single phase alternating electric current, and the positioning being such that the point of emergence is always within the electromagnetic field.

Abstract: A method for controlling the coating of wires, strips or the like, emerging from molten metal baths, involving subjecting the wire to a single stationary, alternating electromagnetic field generated by an electromagnetic device positioned at or below the point of emergence such that the point of emergence is always within the electromagnetic field. The frequency and/or current for generating the field may be adjustable, and the field generated by either parallel or transverse to the wire, strip or the like. The wire, strip or the like may pass through, or adjacent, the electromagnetic device. A neutral or reducing atmosphere may be provided within a chamber situated at the point of emergence and the point of emergence covered with particles inert to the environment. Alternatively the emergence area, may be covered by a confined or unconfined bed of oil charcoal.

Abstract: A method of wiping hot dipped metal coated wire or strip, and an apparatus for performing the method, involving drawing the wire or strip upwardly from a bath of molten metal through a wiping bed located at the point of emergence from the bath, with an interference device being positioned adjacent the wire or strip below the surface of the molten bath such as to restrict the lamella flow of molten metal entrained by the moving wire or strip. The interference device wholly or partly surrounds the wire or strip and is located below the wiping bed, which bed in turn may be laterally confined or unconfined. The interference device may be of any convenient configuration such as in the form of a horizontally disposed flat plate provided with one or more slots, grooves or other apertures through which the wire or strip passes.

Abstract: This specification discloses a method of and apparatus for forming concrete reinforcing elements having enlarged ends and also discloses a reinforced composite incorporating such elements. In one embodiment the enlarged ends are formed by folding the edges of a strip of sheet metal onto itself while in another form the enlarged ends are formed by edge rolling a strip. In both cases the reinforcing element is formed by transversly shearing the strip after its edge has been modified. The reinforcing elements as described above are shown to have a greater pull-out resistance than plain elements.
