Title: Improvements in apparatus for extracting sugar from sugar cane
IPC: C13B10/02
Filed: 1963-10-07
Abstract: Countercurrent diffusion apparatus, for extracting sugar from small pieces of sugar-cane, e.g. shredded sugar-cane, comprises a vertical tower 1 having an upper, tubular diffusion chamber 6 connected, by a tapering part 7, to a narrower conveying tube 3, which is closed at its base 31 and encloses a vertical feed screw 2, whose main shaft 2a is mounted in an upper bearing in the base 31 and a lower bearing on the foundation 21.  The shaft 2a is rotated by a motor 22, through a transmission 23.  The shaft 2a is secured, at 2e, to a surrounding tube 21, which carries the screw flights 2b and widens to form a conically flared lower part 17.  The tube 21 is surmounted by a screening cone 18, which projects into the tapering part 7.  Under this cone is a chamber 2d connected, through channels 2f, to an annular channel 2c between the shaft 2a and the tube 21.  The channel 2c leads into a chamber 24 below the flared part 17.  The chamber 24 has an opening 19 leading into a pipe 20. Pieces of sugar-cane are fed, by a converyer 171, into a tank 4 and are there mixed with sugar juice, preferably heated, supplied from the tube 3, through screens 13 and pipes 14, 15, 141, 151 and 16.  The resulting mixture is fed, through a vertical pipe 5 and its horizontal <PICT:1000599/C6-C7/1> <PICT:1000599/C6-C7/2> extension 5111, into the lower part of the tube 3, where the mixture is deflected upwardly by the flared part 17.  A pump may be provided in the pipe 5.  Water is fed, through pipes 8 and 9, into the upper end of the chamber 6 and moves downwardly through the uniformly distributed pieces of sugar-cane moving upwardly through the tower, due to the rotation of the screw 2.  Exhausted pieces of sugar-cane are removed, by a scraping conveyer 10, from the top of the chamber 6 into a discharge pipe 11. Diffusion juice passes through the screening cone 18, the chamber 2d, the channels 2f and 2c, the chamber 24 and the opening 19 and is discharged from the apparatus through the pipe 20.

Title: Reduction of metal oxides
IPC: G10L21/00
Filed: 1964-09-30
Abstract: In a process for the reduction of metal oxides (e.g. of iron or chromium) they are subjected in the fused condition to the action of a directionally stable plasma arc containing a hydrocarbon gas. The hydrocarbon gas may be methane which may also comprise the arc support gas but this latter may also be A, H2, He, N2, CO, Xe or Ne. In examples the iron oxide or chromium oxide content of a slag is reduced and the metal values descend through the slag into a pool of iron. Small amounts of lime, fluorspar or silica may be added to the slag to make it more fluid.

As shown, the metal orifice ring 10 has an outwardly facing channel 9 receiving end portions of a cloth 11 covering the ring 10. The ring 10 has a sewing ring 15 fitted to it, the shape of ring 15 being determined by the particular valve which is being replaced. A hollow metal ball is held captive between the ring 10 and the metal cage 25 having a plurality of legs 26 meeting at an apex. The legs 26 have hooked ends (27) received in channel 9 (Fig. 3, not shown) and are held on to the ring 10 by windings 12 passing through a groove (28) in the end of the legs 26. The legs are covered by cloth 35, preferably in the form of cloth tubes, which are sewn together at the apex so that the cage is completely covered. The cloth covering each leg is sewn to the ring 15 by stitches 36. The cloth coverings 35 are protected from excessive wear on the inside of legs 26 from the ball 20 by an inner metal cage (Fig. 4, not shown) having legs 41 which form the track bars projecting from grooves 33 in the legs 26. The cloth-coverings 35 are forced into the grooves 33 by the track bars 41 which project from the grooves just far enough to prevent contact between the ball 20 and the cloth coverings 35. The inner cage (40) may be attached to the outer cage 25 by means of pins 42 fitted in holes (43) of the outer cage. In an alternative embodiment (Figs. 5-8, not shown) on each leg (56) of the outer cage a plastic track bar (65) is embedded in a tubular cloth covering (66), a portion of the track bar projecting just far enough to engage the ball (20). In a second alternative embodiment (Figs. 9-11, not shown) an inner cage (75) is cast integrally with the orifice ring (10) and an outer cage (80) is then assembled on the inner cage and its legs (81) fastened between the ring (10) and the sewing ring (15).
