Abstract: Methods for manufacturing a magnetic stripe on a card element of a card-like data carrier. involve applying at least a portion of a magnetic stripe material layer onto a card element surface of the card element using different techniques. The application of the portion of the magnetic stripe material layer onto the card element surface generates a magnetic stripe on the card element surface such that the magnetic stripe has a stripe length that is less than a length of the card element surface and has a stripe width that is less than a width of the card element surface.

Abstract: The present invention is based on a novel electric induction furnace design that enables the removal of zinc-containing filter dust (FD) originating from the production of steel (alloy or non-alloy) and the production of cast iron with galvanized steel scrap, using a novel process based on the carbothermal reduction of the metal oxides present in the FD, performed at the temperature at which the materials are melted inside the electric induction furnace. The electric induction furnace of the invention incorporates an electric arc or plasma beam generator to melt all the inorganic non-metallic material. The incorporation of this generator also enables the use of large volumes of molten slag.
