Patent GB-638934-A (GB)
Title: Improved process for the reduction of iron ores or iron-containing ores
IPC: C21B11/10
Filed: 1947-10-24
Abstract: In a process for the reduction of ironcontaining ores, the ore, with or without slag is melted and charged with carbonaceous material into a closed reduction furnace, the heat for melting the ore being supplied from one or more non-electrical sources other than the direct oxidation of the carbonaceous material which latter is directly oxidized in the reducing furnace by the oxygen of the ore, any additional heat being supplied to the reduction hearth and at least a part of the gases obtained during reduction being collected. The heat for melting the ore may be obtained by the combustion of a gaseous fuel, e.g. town's gas, or coke oven gas alone, or mixed with gases from the reduction furnace, and the additional heat required for reduction may be electrical or by combustion of gases as above. The hot gases produced from any part of the process may be used to pre-heat air and/or the gases used for combustion.  The gases from the reduction hearth may be used to drive prime movers for electrical generators to produce power, which, in turn, is used to provide the additional heat for the reducing hearth.

Title: Improved safety device for hydraulic transmission
IPC: B60T11/32
Filed: 1937-10-19
Abstract: 504,278. Hydraulic transmission of power. SOC. ANON. DES ATELIERS GAMAIN. Oct. 19, 1937, Nos. 28475, 28476, 28477, and 28478. Convention dates, Oct. 19, 1936, March 1, 1937, July 16, 1937, and Oct. 6, 1937. [Class 69 (ii)] [Also in Group XXXIV] Hydraulic transmission particularly for brakes comprises a device in each conduit leading to the brakes arranged to close this conduit from the rest of the system in case of leakage and also adapted to adjust the system for wear. The device comprises a piston 2 containing valves which provide communication between the pipe 17 connected to the master cylinder and the pipe 12 connected to the brake when the piston is at the end of its cylinder 1 nearest the brakes when the pressure difference between the two pipes does not exceed a predetermined value. The piston 2 is forced from one end of the cylinder 1 to the other at each brake application and if wear has occurred the piston stroke increases and a hollow rod 8 engages the end of the cylinder, opens a valve 6 and allows liquid to pass through the piston, to take up the wear. If leakage occurs in the pipe 12, pressure above a piston 14 drops to zero and the pressure below this piston transmitted from the master cylinder via a passage 18 raises the piston and closes the conduit 12 by means of a valve 13. The valve 13 will remain on its seat after release of the brakes if a slight pressure is maintained on the fluid in conduit 17. In a modification, when leakage occurs the rod 8 abuts the end of the cylinder, opens the valve 6, causes cups 26, 27 to abut and holds the valve 5 on its seat to close off the conduit 12. In a further modification the ball valves and cups are replaced by a single ball valve pressed towards the rod 8 by a spring and in a still further modification this ball is replaced by two valves telescoped together. This modification is adapted to release back to the master cylinder excess liquid which may have been forced to the brakes owing to expansion of the brake drums.

When the frame is lowered and the plate 3 rests upon the load, the frame 1 moves downwards on the ram 2 and a pawl 5 carried by the ram engages a star-wheel 8 carried by the frame so as to turn the cams 9, 10 through 90‹. The cams raise the bridge 11 which is connected by links and levers to the arms 15. On lifting, the frame 1 moves upwards on the ram, and the pawl comes into position for engaging the next tooth of the star-wheel 8. On setting down the load, the frame moves downwards on the ram 2 and the cams 9, 10 are moved so as to lower the bridge 11 and swing the arms 15 outwards. The cams 9, 10 may be constructed so as to move the bridge positively in both directions. The pivots of the arms 15 may be adjustable in the frame. The shackle 16 at the head of the frame is shaped so as to bring bell-crank levers 18 into engagement with the pulley-block 42 when the shackle becomes vertical on lifting, whereby the load is prevented from swinging relatively to the block. In a modification, Fig. 4, gripping-arms 19 are pivoted on the shaft 24 and connected by links 21 with the lifting-head 22 of the frame. A ram 28 is free to move up and down in the frame, and carries pawls 32 to engage star-wheels 27 carried by the frame, so as to turn cams 26 through 90‹ on engaging the load and on setting it down. The cams 26 control the position of two hooked levers 34 pivoted in the frame. In the position shown, on lifting the crane-hook, the hooked ends of the levers 34 will engage lifting bolts 33 in the frame and lift the tongs by their pivot pin with the arms open. On lowering on to a load, the ram 28 moves in the frame and the cams are turned so as to push the levers 34 apart, and on lifting the tongs close against the load while the ram falls and the pawls come beneath the next tooth of the star-wheel. On setting.down the load, the cams are again moved and the levers 34 come into position to lift the open tongs away from the load. The spindle 25 of the star-wheel may carry an indicating dial, which may bear against a spring to prevent accidental movements of the cams. Wheels 38 are provided on the arms 19 for movement over the ground or on rails.
