Abstract: ABSTRACT     A method and apparatus for manufacturing sponge iron by the continuous reduction of iron oxides in a shaft utilizing recirculation gases.   Reaction gas is removed from the shaft furnace, substantially cleaned of all C02 and H20, and then divided into at least two flow portions one of which is passed to a gas generator comprising a gas generating shaft substantially filled with a solid reducing agent and a plasma burner arranged in the lower portion of said shaft.   An oxidant is injected into the hot gas from the plasma burner so as to form a gas mixture mainly comprising CO and H2, which gas mixture is then mixed with the other flow portion of the cleaned reaction gas in such a proportion that the temperature of the resulting reduction gas is suitable for the reduction of iron oxides in the shaft furnace.  The reduction gas is then injected into the shaft furnace and passed upwardly to reduce iron oxides contained there to form sponge iron which is then removed.

Abstract: ABSTRACT           V-MOS Device with Self-Aligned Multiple Electrodes High density VMOSFET devices, particularly single transistor memory cells, are provided by use of series of simplified self-aligning process steps. Gate electrodes, source/drain regions and source/ drain contacts are provided with the aid of an initial mask-less photoresist removal process in which a relatively thick layer of self-leveling photoresist is uniformly removed in order to define portions of a gate electrode within the recess of a V-groove.  The gate electrode subsequently acts as a self-aligned mask to define implanted source/ drain regions also within the V-groove and to enable second level interconnecting metallurgy contacts to be formed along the sidewalls of the V-groove.

Abstract: ELECTRIC FUSE HAVING GAS EVOLVING MEANS         FOR LIMITING BURNBACK                    Abstract of Disclosure The process of circuit interruption by an electric fuse can be initiated either by a protracted overload, or by a major fault current of large proportions.  This invention is concerned with the latter kind of fault currents.    A substantially U-shaped gas-evolving structure is inserted between parallel rows of fusible elements.  The two parallel arms of that structure are positioned close to the terminal elements of the fuse.  A tie member interconnecting the two arms is positioned substantially out of the arcing zone and parallel to a generatrix of the fuse casing.  On occurrence of a major fault current, the gas evolved from the arms protects the terminal elements of the fuse.  It also tends to quench the follow current, i.e. the current which flows through the hot fulgurite after a successful inter-ruption of a major fault current.
