Abstract: 730,724. Grain cutting machines. SYMONS BROS., CO. Oct. 8, 1952, No. 25268/52. Class 59. [Also in Group I] A grain cutting machine comprises a rotor 30 and a cutting ring 60 having co-operating cutting surfaces adjacent their peripheries, the ring being free to rotate about an axis parallel to, but offset from, the axis of the rotor. The rotor is rotated at such a speed, e.g. on a vertical motor-shaft 2, that grain fed on to its central part 40, e.g. through an axially adjustable duct 16 about which the cutting ring rotates, is flung to the periphery of the rotor where it strikes the inner surface of the cutting ring and causes the latter to rotate. The rotor may be a reversible disc having identical concentric ridges 32, 36 and 38 on both its faces. The surfaces of these ridges, i.e. the cutting surfaces, may be flat and may lie in a plane normal to the rotor axis. The grooves between the ridges may be of uniform depth to gauge the size of grain. Alternatively, the innermost grooves may be deeper than the outermost. The cutting ring may be frusto-conical or doubly frusto-conical (the latter form being reversible) with a cutting rim or rims 64. The inner surface or surfaces of the cutting ring may have outwardly radiating ridges.

Abstract: 425,006. Coin-freed table game apparatus. MILLEDGE, S. Z., Taunton Farm, Taunton Lane, Old Coulsdon, Surrey. Sept. 3, 1934, No. 25352. [Class 132 (ii)] [See also Group XVIII] In table games wherein discs or like flat elements are slid over a horizontal scoring board, a transparent window is disposed above the board and spaced therefrom just sufficiently to permit free passage of the playing elements. The apparatus may be coin-freed, in which case the board and window are pivoted about their combined rear edge, and, may be raised about this pivot so that played elements slide from the board into a receptacle from which they may be discharged for further play. The playing board comprises a main member 15 and side scoring members 16 secured to a base 17, the board and the glass window 19 being pivoted at 18 to a casing 10 mounted on a support 11. The playing elements are projected as in shovehalfpenny from the front end 21 of the board which projects beyond the front end of the window, and are secured for replay by tilting the board about the axis 18, the discs falling into a shoot 22 the bottom of which is cushioned to prevent damage to the discs and is shaped so that the discs will be returned by gravity through a slot 25 to a tray 26. Coin-freed mechanism. At each tilting movement of the board a spring 29 connected thereto at 30 rocks a rod 27 to the left to uncover the slot 25 and also advance a ratchet wheel 34 one tooth. The ratchet also coacts with a weighted detent 35 pivoted at 36, which, after a predetermined number of steps by the rod 27, engages a stop tooth 41 to look the wheel. On the next tilting movement of the board the discs fall into the shoot 22 but are prevented by the rod 27 from passing to the tray 26. To release the rod, a coin is inserted in a slot 40, and, falling down the channel 39 impinges on a projection 43 rigid with the detent 35, rocking the latter to release the wheel 34 which is immediately advanced by the rod 27, the coin falling into a box 12. In another construction the coinfreed mechanism is arranged to prevent the board from being raised until a coin is inserted. A counting mechanism preferably actuated by the wheel 34 may be provided for counting the coins. The wheel 34 may be replaced by a member capable of angular or sliding movement.

Abstract: 716,592. Centrifugal machines. MAATSCHAPPIJ VOOR KOLENBEWERKING STAMICARBON N.V. Oct. 17 1952 [Oct. 17, 1951; Sept. 26, 1952], No. 26068/52. Class 23 [Also in Groups VI, XVII and XIX] Apparatus for dividing a liquid flow into different parts in accordance with viscosity comprises a chamber in which a vortex of the liquid is formed, an outlet from the chamber discharging the liquid as a conical sheet having an apex angle depending on the viscosity, and at least one collector co-axial with the outlet from the chamber. The apparatus may be used to divide a liquid flow in accordance with other properties, such as density, which alter with viscosity. As shown in Fig. 4, the liquid. is supplied to the chamber 21 by a tangential pipe 22 and is discharged through the outlet 26. Collectors 27, 29, 33 coaxial with the chamber are connected to conduits 28, 31, 35, the arrangement being such that the conduits discharge liquid of successively higher viscosity. Screw fittings 25b, 36, 37 permit control of the diameter of the outlet and the heights of the upper edges of the collectors 29, 33 so that the conduits may discharge different viscosities. The supply of liquid to the chamber may also be' varied so that the conduits discharge different viscosities. In the modification shown in Fig. 3, the chamber 1a has a core 9 which may be rotary, and the distance of the chamber from the collectors 4a, 6a may be varied. In the suspension thickening plant shown in Fig. 5, multi-hydro-cyclones 43, 44, 45 in series are supplied with suspension from a pipe 40. Thickened suspension from the cyclone 43 passes through the chamber 47 so that if of the required density it is discharged by the conduit 48 but if below the required density it is returned by the conduit 49 to the cyclone 43. The denser discharges from the cyclones 44. 45 are also returned to the cyclone 43. Dimensions and performance figures for the apparatus are given in the Specification.

Title: Improvements relating to mixing machines
IPC: B28C5/12
Filed: 1952-10-20
Abstract: 714,025. Mixing appliances. AUGUST, P. and FORTA, L. A. Oct. 20, 1952, No. 26266/52. Class 86 In a mixing machine, especially for concrete, a sloping mixing worm is fitted with cut-outs at regular intervals and is surrounded by a mixing trough arranged parallel to the mixing worm to which the mix is supplied at the lower end, and the gap between the outer periphery of the mixing worm and the wall of the mixing trough continuously widens in relation to either a point of the periphery or a point of the trough as the worm rotates, to avoid jamming of the mixer by grains of material in the gap. In Fig. 4, the mixing worm 5 of a concrete mixer is mounted eccentrically in the trough 1 forming a crescent-shaped gap S within the zone occupied by the mix M, the tip of the crescent on the entrance side of the worm being above the level of the mix. As the worm 5 rotates in the direction of the arrow A, a stone such as 27, in the gap S, is taken in the direction of the arrow A towards the wider end of the gap S. In a similar arrangement, Fig. 5 (not shown), the crescent-shaped gap is obtained by forming the trough with a slightly spiral section. In concrete mixers the gap at the point B, Fig. 4, should be not greater than 2 mm. and to compensate for wear in this respect, the bearings 8, Fig. 7, for the worm shaft 6, are slidably adjustable along guides 30, 31 and are held in adjusted position by means of screws 34, 35. In an alternative arrangement, Fig. 6, individual segments of the worm 5 can be cut so that a crescentshaped gap S results which continuously widens in relation to a point on the trough as the worm rotates. In order to prevent the formation of a crust upon zones of the trough in the region of the cut-outs in the worm, the worm is arranged or fitted so that each part of the trough touched by the mix is swept at least once by a part of the worm at each rotation of the worm. In Fig. 8. a double worm is provided having the cut-outs 25a in one partial worm 5a located in the region Z of the trough also occupied by non-cut-out sectors 26b on the other partial worm 5b. In Fig. 10 bridge pieces 50 are provided across the cut-outs 25 of the worm 5, and in another arrangement, Figs. 11 and 12 (not shown), a pair of longitudinal cross pieces extend helically along the periphery of the worm. In a further embodiment, Fig. 9 (not shown), the worm is formed by sectors so arranged that the cut-out has no advance along the worm. The invention can be applied to a continuously working machine, Fig. 1 (not shown), or to an intermittently working machine, Fig. 2 (not shown).

Abstract: In the leaching of nickel and associated non-ferrous metals, i.e. Co and Cu from high-grade nickel matte which contains also S, Fe, one or more of the precious metals Pd, Pt, Ag and Au and at least one of the metalloid elements As and Sb to ensure minimum dissolution of As and Sb, a slurry of the finely-ground matte is formed in aqueous H2SO4 the total sulphur content of the slurry being at least the stoichiometric amount required to combine with the non-ferrous metals content of the slurry as sulphates; the slurry is subjected to a first leach at a temperature above 250 DEG  F. (preferably 275 DEG to 300 DEG  F.) and under a partial pressure of O2 above 10 p.s.i., this first leach being terminated at a slurry pH of 3.5 to 5.5 (preferably 4.5 to 5.0); the solution is separated from undissolved residue which is subjected to a second leach at a temperature above 250 DEG  F. and under a partial pressure of O2 above 10 p.s.i., this leach being continued until substantially all the Ni, Co and Cu is extracted; the second leach solution is separated from undissolved residue and is treated together with the first leach solution to remove Cu and Fe and the purified leach solutions are treated for the recovery of Ni and Co.  The undissolved residue from the second leach may be passed to a precious metals recovery operation and the first leach solution may be passed directly to the Ni and Co recovery steps without treatment for Cu and Fe removal.  Cu may be removed from the leach solution by treatment with H2S and Fe and residual As precipitated by adjustment of the solution pH to 4.5 to 5 by addition of ammonia.  The second leach solution may be treated to remove residual As by addition of Fe in an amount in excess of ten times the As content of the solution.  The Ni and Co are obtained by known H2 reduction techniques after adjustment of the solution with ammonia and ammonium sulphate and the previous metals may be recovered from the undissolved residue by conventional processes such as cyanidation.
