Title: Improvements in or relating to the reduction of ferruginous ores
IPC: C22B1/02
Filed: 1948-10-06
Abstract: <PICT:0658200/III/1> Ferruginous ores &c. are treated for the conversion of their iron oxide content into magnetite by causing the comminuted ore to descend chambers in series, passing upwardly through the upper chamber a mixture of carbon dioxide, carbon monoxide and hydrogen at an elevated temperature below the liquidus temperature of the non-magnetic iron oxide compound in the ore, the volume and composition of the gas being such that at the temperature of operation, it is oxidizing with respect to FeO and Fe, is reducing with respect to Fe2O3 and is in equilibrium with Fe3O4, passing the treated ore material down the lower chamber in counter-current to a stream of reactive gas of such composition that after heating it is the same as the initial reactive gas, withdrawing the gas from the second chamber, heating it and using the heated gas for treatment of further ore material in the upper chamber.  As shown, the ore is fed from a gas-seal hopper 22 into chamber 16, passing through it against a stream of reactive gas fed through bustle 12, and through a restricted conduit 7 into the second chamber 5 through which it passes to star-gate 40 against a stream of reactive gas entering from bustle 3.  The "spent" gas from chamber 16 is circulated by blower 1 through a dust collector 26, cooler or scrubber 28 and, maybe, an electrostatic precipitator to the bustle 3, a certain amount of gas being bled through line 30 and fresh reducing gas being added through conduit 31.  After traversing chamber 5, the gas passes through conduit 9 to a combustion chamber 10 wherein its temperature is raised to below 1300 DEG  C. (at which the ore melts) by the combustion of fuel, e.g. oil, gas, powdered coke, &c. supplied to water-cooled burner 35 in just sufficient air supplied through bustle 33.  The heated gas thereupon passes through conduit 11 to bustle 12. The volume of reactive gas may be 10 cu.ft. per lb. iron in the ore, and of the reducing component 1-1.37 cu.ft. per lb. iron.  To ensure uniformity of the gas flow, gas-collecting pockets 4, 6, 14, 19 are provided within the chambers.  Uniformity of solids flow within chamber 5 is ensured by conical baffles 45.  The chambers 5, 16 may, if desired, be placed side by side, at any convenient levels, transfer of material being effected by bucket conveyers, &c. Prior to treatment, the ore material may be dried, using, for example, the equipment disclosed in Specification 647,490.  The process is applicable to ores containing iron either as ferrous oxide or carbonate, or ferric oxide, and to blast furnace dust, which may be agglomerated prior to roasting.  Specification 658,199 also is referred to.

Abstract: 652,781. Packing hops; baling presses. EDWARDS, H. A. Oct. 11, 1948, No. 26399. IClass 94(i)] [Also in Groups XXIV and XXXIV] An actuating mechanism for a machine, comprising a reciprocatory ramming head, for packing hops, comprises the combination of a pair of shafts one of which is adapted to transmit motion to the packing machine and the other to receive motion from a source, one of said shafts being movable in a lateral direction relatively to the other, a friction pulley on one of the shafts, a pulley (or pulleys) on the other shaft providing inner and outer peripheral surfaces of different diameters with which  the friction pulley can co-operate, a lever mechanism adapted to impart lateral movements to the laterally movable shaft, and a hand lever adapted to actuate the said lever mechanism in one direction through spring means and in the other direction directly. A ramming head a of a hop packing machine is movable vertically by rack and pinion b, c driven through gears i, f, from a shaft h mounted in a framework g. On the shaft h is mounted a disc j formed with an outwardly facing inner peripheral surface m and an inwardly facing outer concentric peripheral surface k of a larger diameter; alternatively a pair of separately formed discs may be mounted on the shaft. A driving shaft n, parallel to the shaft h and carried by a pair of pivoted arms p, has mounted thereon a friction disc o adapted to engage either the outer peripheral surface k, in which case the ramming head a is given a relatively slow downward, compressing stroke, or the inner peripheral surface m in which case the ram a is given a relatively rapid upward, withdrawal stroke. The arms p are connected by links to a rocker shaft t mounted in framework g to which shaft is secured a long forked arm w, pivoted at x between the arms of which is an operating lever y which moves the lever wand thus the disc o in one direction through springs 2, movement being limited by a stop 4 on the frame, and in the other direction by contact with an abutment 3 on the arm w. A spring 6 tends to return the arm w to a neutral position. A brake shoe 8 adapted to bear on the disc j is carried by a spring-loaded arm 7 pivoted at one end to the frame g and bearing at its other end, through screws 10, carried thereby on a pair of short arms 11 extending from opposite sides of the rocker shaft t and so inclined relative to the shaft t that when the lever w is in either of its operative positions the brake is lifted off the disc j but when in the neutral position the brake is pressed on. A lever 12 pivoted to the frame g is adapted to be engaged by the ram a at the end of its upward stroke to cause, through a chain 13, the lever w to be returned to the neutral position. As a modified construction the two-part disc may be mounted on the driving shaft and the other disc on the driven shaft.
