Title: Improvements in or relating to process of pouring metals and products produced thereby
IPC: B22D43/00
Filed: 1947-08-26
Abstract: 648,321. Casting processes ; mould materials. VANADIUM CORPORATION OF AMERICA. Aug. 26, 1947, No. 23535. Convention date, Aug. 27, 1946. [Class 83 (i)] [Also in Group II] To ensure complete separation of metal and slag after smelting ore to form high-carbon ferro-chromium or other refractory metal this is poured into a mould containing a fluid slag which has cooled to form a thin shell of solid slag. A suitable casting slag may be made by adding silica sand to a waste slag to give the desired fluidity. For a tap of 8 cubic ft., 16 cubic ft. of the casting slag 4, heated to 3000- 3100‹ F., are placed in a mould 1 of 34 cubic ft. capacity. The mould 1 is placed so that the slag surface is about 35 inches below the spout 3 and, after 5 to 10 minutes to allow a thin shell 6 of chilled slag to form, the ferrochromium 7 and smelting slag 8 are poured for 4 to 20 minutes. The solidified ingot is removed from the mould and the slag broken away. Moulds.-In smelting ore to form low-carbon ferro-chromium comprising chromium 70.21 per cent, silicon 0.68, carbon 0.58 and the remainder substantially all iron, a more fluid slag may be obtained and this is first discharged into an empty mould comprising cast iron parts 12, 14, 16, 19 with a graphite plug 18 and over-flow 20 for excess slag. After allowing 5 minutes for the shell 6 to form, pouring is continued through 25 to 19 inches of slag excess overflowing at 20. From 10 to 15 minutes after pouring is stopped the plug 18 is removed to reduce the slag layer to 6 inches. The ingot is stripped after 5 or 6 hours. It is however preferred even with low-carbon ferrochromium to pour through a special casting slag and this may be made by treating some of the smelting slag with chromiurn-silicide, ferrosilicon, or aluminium and then adding silica sand. The slag in the mould should be over 12 inches deep during pouring and the height of pouring less than 6 ft. The shell thickness should be between <SP>1</SP>/ 64  and 1 inch and the metal within it may be tapped off into separate moulds before solidifying. The invention may be applied to vanadium, titanium, zirconium, columbium, tantalum, uranium, or alloys thereof.

Title: Improvements relating to pole-changing switches for dynamo-electric machines
IPC: H01H35/12
Filed: 1947-08-27
Abstract: 634,472. Actuation of switches. STONE & CO., Ltd., J, and NIXON, L. R. Aug. 27, 1947, No. 23692. [Class 38 (v)] Actuating mechanism for the pole-changing or armature-reversing switch of an axle-driven train lighting generator comprises light pawls rotatable with the shaft of the generator and initially spring-biassed in position for operating the switch when the shaft commences to rotate, the pawls being retracted from the operative position when the speed of rotation increases by the influence of centrifugal force acting on weight bodies separate from the pawls. In the arrangement shown in Figs. 1 and 3 a reversing switch comprising fixed contacts 11 and drum contacts 7 is carried by the brush rocker 1 of the generator and is actuated by either of pawls 30, 31, according to the direction of rotation of the generator shaft 29. Toggle mechanism comprising dead-centre springs 49 and link 52 hold the switch in its end positions. The pawls are pivoted at 32 to a disc 33 attached to shaft 29 and their tips 34 are urged outwardly to engage the ears 28 of the operating arm 25 of the drum by tension-springs 38 anchored to pins 40. The last are carried by centrifugal weights 35 which pivot on the same axes as the pawls and which are connected together by equalizing linkwork 45, 47. A spring 43 urges the tails of the weights together, so that when the shaft commences to rotate the pawls fully project and can strike the switch operating ears 28, but as the speed of the shaft increases the tails move outwardly and the resulting motion of the pins 40 withdraws the tips of the pawls clear of the ears 28. Fig. 7 shows a modified switch construction for larger current machines. The switch comprises fixed contacts 76 and laminated change-over contacts 74 carried by a rocker 68 which pivots about the shaft 29 and has an extension 67 rigid therewith and acted upon by a toggle mechanism 58-66. Under the action of the pawls 30, 31 the toggle mechanism throws the contacts 74 into one or other of their operative positions, contact pressure then being increased by the attraction between an electromagnet 70, 71 (carried by the rocker extension 67) and one or other of two keepers 72. The magnet coil may be energized by the whole or part of the load current of the generator, or by the voltage obtaining across contacts 74. A spring connection may replace the direct coupling between the toggle link 58 and the rocker extension 67.

Rail tracks, switch points, and cross-overs are built up of fabricated elements comprising members of rolled, onepiece I-sectioned mild steel upon which tread portions or wear-plates made of highresistance steel are secured by welding. The track portions may oe grooveu or otherwise. In the examples described the I-sectioned girders have wide upper flanges from which portions are removed in assembling a frog crossing, as shown in Fig. 3, in order that the webs g may be juxtaposed as necessary. Longitudinal and transverse reinforcing members f, f<SP>1</SP> are welded to the webs at the intersections, and stiffening ribs j are also welded at intervals. Fig. 5 shows a cross-section of part of the frog crossing, with a hardened steel tread-plate a seated on the supporting frame and secured thereto by welds p. The correct position of the plate a may be determined by recessing its underside to form shoulders h which engage within recesses in the flanges e of the support. As shown, the plate a is provided with a pair of grooves b which converge and intersect to form the frog. The element is supported on a bed-plate k which extends beyond its ends and beneath extension rails l which join the element to stock rails d. The extension rails are welded to the bed-plate k and braced by solid blocks m in the frog-angles or by spacers n, Fig. 2 (not shown) consisting of acute-angled plates which rest on the reinforcing members f<SP>1</SP>. The solidity of the assembly may be increased by transverse bolts o or by metal pins which are secured at their extremities by welding.
