Title: Improvements in iron recovery
IPC: C21B13/12
Filed: 1953-05-11
Abstract: Iron oxide bearing material is reduced by mixing the material with carbonaceous material and fluxing material, heating the mixture under reducing conditions to form a granular material containing some iron and unreduced ore in combination with fluxing material, charging the granular material on to the surface of a molten slag bath, maintaining the slag bath at a temperature high enough to supply all the heat required to reduce the iron oxide to metal, and finally separating the metal from the slag.  The iron oxides, carbonaceous materials and fluxes may be ground to pass a 4-mesh sieve and fed to a rotary kiln heated by the combustion of carbon monoxide generated in an electric furnace in which is maintained a slag bath.  The sintered granular material from the kiln is fed on to the surface of the slag bath in the electric furnace and the reduction of the iron oxide completed.  In a modification a small amount of carbonaceous material may be used to produce some iron containing in solution any non-ferrous metals and phosphorus present in the charge, this impure iron being removed and the remainder of the material, with the addition of carbonaceous material, reduced in another furnace.  The sintered granular material may be added to the slag bath at a temperature of not less than 1,000 DEG C.  The amount of carbon in the finished steel may be controlled by varying the amount of carbonaceous material in the charge.  The electrodes should be maintained between 1/2 inch above the surface of the slag and 2 inches below the surface and the depth of charge material should not exceed 12 inches around the electrodes.

IPC: F41G1/393
Abstract: 132,289. Dawson, Sir A. T., and Buckham, Sir G. T. June 7, 1918. Sights. - Relates to guns having an independent line of sight, and consists in correcting the sight for drift when the gun is elevated for range by means of a screw gear, such as previously proposed for guns not having an independent line of sight. In the form shown, the gun is pointed by a pinion a and ranged by another pinion b, and the sight-carrier C is connected by a forked arm C<3> to a pivot C<2> on a screw spindle C<1> in engagement with a nut B<1> fixed to the hollow end of the trunnion B, the spindle being prevented from rotating by a pin c<2> projecting from an arm c<1> on the spindle into a hole in the sight-bracket A. The relative rotation between the spindle C<1> and the trunnion B causes a longitudinal displacement of the spindle and a consequent rotation of the sight-carrier C about a vertical pivot on the sight-bracket A to correct for drift. Back-lash is prevented by a spring C<4> between the bracket A and the arm C<3> of the sight-carrier. The screw-threads of the gear may be of unequal pitch designed to give the exact drift correction required.
