Abstract: 1428590 Reduction of iron ore FIERRO ESPONJA SA 8 Oct 1974 [16 Oct 1973] 43580/74 Heading C7D A process for the production of sponge iron involves a plurality of interchangeable reactors for alternatively charging and discharging, reducing, and cooling, in which a portion of the effluent gases from both the reduction reactor and cooling reactor are recycled to their respective reactors. In Fig.1, reducing gas (CO+H 2 ) produced in reformer 26 is cooled and fed by pipe 36 to reactor 10 where it cools and further reduces oxide already largely reduced in the reduction stage. The effluent gases from reactor 10 are cooled, part being fed either to heater 88 and reactor 12 (undergoing the reduction stage), and the remainder to pipe 58, pump 66, pipe 32 and back to reactor 10. The gas is heated in heater 88 to 700-850C and is brought to 900-1100C by passing through a super-heater 122 or a combustion chamber where it meets heated O 2  or air from heater 100. The effluent gas from reactor 12 is cooled, part being removed from the system by pipes 130, 64 and 142 for fuel purposes, the remainder passing through pipes 130, 64, 76, 84 and back into the reactor via heater 88. In the meantime, reactor 14 has been discharged of reduced ore and charged with oxide, which may be in lump or pellet form. When the reduction stage is over, reactor 12 becomes the cooling reactor, reactor 14 the reduction reactor, and reactor 10 is discharged and charged. In another embodiment Fig.2 (not shown), a single heater (356) replaces the heaters 82,88,94.

Abstract: 1,201,983. Vehicle suspensions. HOESCH A.G. 13 Sept., 1968 [9 Oct., 1967], No. 43748/68. Heading B7D. [Also in Division F2] Hydropneumatic suspension units of the form shown when combined with high and low pressure liquid sources (not shown, but connected respectively to lines 38 and 33) provide a selflevelling vehicle suspension the action of which is insensitive to transient shocks. From the "normal" condition shown, excessive inward movement of the piston 19 causes the stop 351 on the tube 35 to lift a valve element 43 and so connect the below-piston space 26 by way of a port controlled by a valve 46 and the bore 31 of the hollow piston-rod to the high pressure inlet line 38. This moves the piston back out. On excessive outward movement of the piston, the same stop 351 is engaged by the piston and so lifts a valve element 41. This connects the below-piston space 26 to the low pressure line 33 and so moves the piston back in. The valve 46 is a one-way valve so arranged as to prevent pressure equalization between spaces 26 and 31; and the port associated with this valve has a damping or delaying function such that level regulation is not initiated by transient shocks. The high and low pressure liquid sources 39, 34 (Fig. 3, not shown) may be inter-connected by a pump (49) driven by the vehicle engine or an electric motor or by the relative movement of the spring and unsprung parts of the vehicle. The suspension unit shown, which includes a spring constituted by the gas 27 loading the liquid 29 in communication with the space 26, may be used in combination with a metallic spring.
