Abstract: 565,946. Furnaces. BIRMINGHAM ELECTRIC FURNACES, Ltd., ROBIETTE, A. G. E., and HANCOCK, P. F. Feb. 27, 1942, No. 2568. [Class 51 (ii)] [Also in Group II] Austenitic manganese cast iron alloys are decarburized in a furnace by an agent which is relatively non-oxidizing to the manganiferous austenite, but is decarburizing to the carbon content. The decarburizing agent may be gaseous and containing one or more of hydrogen, water vapour and carbon dioxide, carbon monoxide being also present when carbon dioxide is used and in sufficient proportion to prevent the oxidation of the austenitic or in solid or liquid form, e.g. molten barium chloride with or without barium oxide, or a mixture of sodium chloride and manganese dioxide. The treatment is carried out at a temperature between 700‹ C. and the temperature of incipient fusion of the alloys. The treatment of castings of an alloy containing 9-25 per cent of manganese, 2-6 of carbon up to 2 of silicon and not more than 0.15 of phosphorus is referred to. Part of the manganese may be replaced by nickel and/or copper to such an extent that the alloy may contain up to a total of 24 per cent of nickel and copper, the manganese content being not less than 5 per cent. Other elements, such as chromium, molybdenum, titanium, tungsten and vanadium, may be present in individual amounts of up to 5 per cent. but not exceeding 12 per cent in all. If the castings are of relatively thick section, the castings may be recarburized as described in Specification 565,887, [Group II], so as to average out the carbon content at the surface.

Abstract: 620,866. Pulleys ; lifting slings. CALDWELL, L. M. Jan. 28, 1947, No. 2594. Convention date, March 11, 1943. [Classes 78 (iv) and 78 (v)] A lifting sling comprises a load-carrying frame, a pulley-wheel rotatably mounted therein, a rope, cable or the like extending over said pulley and arranged to be attached at its opposite ends to the load, and means for automatically locking the wheel against rotation when the rope, cable or the like is put under tension by the load so as to prevent changing of the lengths of the sling legs. In the embodiment shown in Figs. 2, 3, the cable 12 of the sling passes round a pulley 13, the axle 15 of which is supported on springs 27 carried by bolts 26. These bolts are suspended by nuts 30 from bosses 24 integral with face plates 17 of the wheel supporting frame 18, passing through holes 28 at the opposite ends of the axle 15 and holes 29 in the bosses 24. When the ends of the cable are attached to the load and the frame 18 lifted by a crane hook, the cable first adjusts itself about the pulley and then becomes taut. The load imposed on the pulley compresses the springs 27 whereby the pulley is moved downwards and the flanges of its groove frictionally engage the sides 36 of brake-shoes 31, 32 loosely mounted on bolts 33. The faces 38 of these shoes contact the cable extending round the lower part of the pulley so as to prevent the cable slipping on the pulley when this is held against rotation. Spring means may be provided for normally urging the brake-shoes apart. In a modification, Fig. 5, the flanges on the pulley engage a brakeshoe 40 which is provided with a groove 44 to accommodate the cable 12. The shoe is mounted on a bolt 41 but may be rigid or integral with the frame 18. In a further modification, Fig. 8, the pulley wheel groove 35a is notched at intervals as at 45 to receive the links of a load chain and when the pulley is depressed by the load, it is locked against rotation by a brake-shoe 40a engaging this groove.
