Title: Process and apparatus for lixiviating ores of precious metals
IPC: C22B3/02
Filed: 1934-03-23
Abstract: 428,562. Lixiviating ores. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. March 23, 1934, Nos. 9189, 9190, and 9191. Convention dates, April 13, 1933, Oct. 25, 1933, and Dec. 20, 1933. [Class 82 (i)] In the lixiviation of ores containing precious metals, the lixiviation container works in a circuit with a vacuum filtering apparatus in such a manner that solid substance and filtrate obtained by the filtration of the slime are again united after the solid substance has been permeated with air and the filtrate has been exposed to the action of gases rich in oxygen, e.g. ozonized air. For treating gold ores with cyanide liquor, the cyanide liquor from a tank a is led by the path 1 to a lixiviation tank band fed thereto by a sprinkler pipe so that it falls through the atmosphere, and the ore is fed to the tank b at o. The mixture of liquor and ore is stirred thoroughly and then the slime is supplied by a pump c to a vacuum filter d. The filter cake formed is, during the filtering operation, highly permeated with air and is then fed again to the tank b for further treatment. The filtrate is passed through a deaerator e and thence by a pump g through the path 4 to an aerator h in which it is saturated at atmospheric pressure with air, oxygen or ozonized air supplied at n. The solvent power of the liquid for the air &c. may be increased by diminution of the temperature of the liquid. The liquid then passes back to the tank a and so into the lixiviation circuit again. As soon as the liquor in the tank b has dissolved out the main portion of the gold, the filter cake from the filter is passed to the tank k as well as fresh liquor from the tank 2<1> by the path 7, the slime from the tank k being passed to the filter as before. The solid material resulting from this filtration is passed to a dump and the filtrate treated as before. The filtrate, rich in gold, of the first lixiviation in the tank b is passed from the de-aerator e by the paths 4, 4<a> to a zinc precipitation plant m, the liquor being then passed by the path 9 to the aerator h and thence by the tank 21 to the tank k where it is lixiviated as before. In a modification, the lixiviation and filtration are carried out in the same container, which contains two series of filter elements, the elements of each series being placed one on the top of the other. Each filter element is connected by an individual pipe with a branch pipe leading to a de-aerator and therefore connected to a vacuum pipe. In this form the solid substance adhering to the outsides of the filter elements is de-aerated when the level of the liquor descends in the container.

Title: Process for the separation of meta-dialkylbenzenes from hydrocarbon mixtures containing the same
IPC: C07C7/152
Filed: 1953-04-07
Abstract: A m-dialkylbenzene is separated from a hydrocarbon mixture as herein defined by extracting at a temperature not above atmospheric with an extraction agent comprising a compound of aluminium chloride or bromide with a m-dialkylbenzene or a higher alkyl benzene, i.e. containing more than two alkyl substituents. The hydrocarbon mixture contains m-dialkylbenzene(s) with one or more monoalkylbenzenes and/or other dialkylbenzenes.  It may contain saturated hydrocarbons but substantially no unsaturated aliphatic hydrocarbons or higher alkylbenzenes should be present. In particular, narrow boiling range fractions, especially xylene mixtures which may include ethylbenzene, are treated.  The aluminium halide compound generally contains 2 mols. of halide to 1 of the alkylbenzene with a small deviation in either direction. HCl or HBr may also be present, e.g. in an amount of 1 mol. per mol. of alkylbenzene.  The extraction agent can be made by leading HCl or HBr through the aluminium halide and alkylbenzene at, say, 0 DEG  C.  It takes up further m-dialkylbenzene from the hydrocarbon mixture to form a complex of the type Al2Cl6, m-xylene, (m-xylene)n, where n may be 1-5.  These n molecules are easily split off and recovered as by extracting with a saturated hydrocarbon and distilling the extract.  Extraction of the hydrocarbon mixture may be effected in presence of a saturated hydrocarbon, suitably using the two extraction agents in counter-current to one another.  A diluent may be added, e.g. liquid HCl or HBr when, however, pressure is required to maintain the liquid state.  In examples p- and m-xylene mixtures dissolved in n-heptane are extracted with Al2Cl6 m-xylene containing HCl, at 0 DEG  C. in one stage or in a 12-stage system wherein the mixture is introduced in the 5th stage, the halide compound + HCl in the 12th, and n-heptane + HCl in the 1st.

Filed: 1945-04-16
Abstract: 605,324. Endless-belt conveyers. MAVOR & COULSON, Ltd., and THOMSON, J. April 16, 1945, No. 9411. [Class 78 (i)] In a belt-training unit of the type comprising one or more belt-supporting idler rollers borne by a swivel-mounted base and separate side contact rollers arranged in alignment with the idler rollers, the side rollers have bearings whereby, when these rollers are rotated by engagement with the belt, they are subjected to considerably greater frictional resistance than are the idler rollers. When the idler rollers are arranged to form the belt into a trough, each contact roller is so mounted or shaped that it presents to the belt a rolling surface that inclines upwards relative to the adjacent idler roller surface. Each contact roller has an enlarged outer part that limits sidewise displacement of the belt. The contact roller 16, Fig. 4, is supported by brackets 15 with its axis slightly inclined to that of the roller 9 and has an enlarged part 16B, the inner face of which is formed with a number of rounded projections 17 to engage the edge of the belt. The roller is mounted on a hollow journal 16c of substantial area which is welded to the brackets and imposes a frictional drag. The idler rollers 7, 8, 9 are mounted on ball bearings 10A in brackets secured to a base-plate 11 which is supported by ball bearings 14, Fig. 6, on a lower base-plate 12. The plate 11 is maintained in position by a central pin 21 screwed into it and its rotational movement is limited by pins 19 extending into slots 20. Lubricant is supplied to the ball-race by conduits 22 and is retained by a ring 23.

Filed: 1943-06-11
Abstract: 573,483. High - frequency ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., and WELCH, D. F. June 11, 1943, No. 9487. [Class 7 (iv)] In a high-frequency electrical ignition system, the voltage obtained from a primary source such as a magneto, generator or coil is utilised to charge a condenser which in turn discharges through a spark gap, a high-frequency transformer having its secondary connected to the plugs being included to step up the highfrequency voltage, the constants of the highfrequency circuit including the capacity, the inductances of primary and secondary transformer windings and the shunt capacity across the plug circuit are such that the harmonic and fundamental frequency components of the high-frequency voltage become additive early in the first quarter cycle of the fundamental frequency. If C1 is the capacity of the condenser at the primary side of the transformer, L1, L, the inductances of the primary and secondary windings and C2 the shunt capacity across the transformer secondary, then for maximum transforming efficiency the coupling coefficient M/#L1L2 should be a maximum and in any case greater than 8. The high coupling coefficient is obtained with an air-cored transformer with the ratio of diameters of the two windings preferably greater than À8 and a winding length comparable to, but not substantially less than the diameter of the winding. Preferably, a transformer having interleaved primary and secondary winding layers is employed. Specifications 537,317 and 545,857 are referred to.

Title: Improvements in Friction Drop Stamps or Hammers.
IPC: B21J7/36
Filed: 1918-06-14
Abstract: 123,256. Alldays & Onions Pneumatic Engineering Co., and Wilson, P. J. June 14, 1918. Power hammers.-In a friction lift drop-hammer, means such as a tappet-operated band-brake tightening and releasing gear is employed to work the trip i continuouely while the operating handle v is kept depressed, and also further means may be provided whereby the trip is caused to give single blows only. The latter means comprises a cam roller 1 which engages a cam face on the trip i during its upward movement, and moves an adjustable support 2 beneath the trip i. At the required moment the support 2 is removed by turning a handle 4, the trip falls, and is immediately raised again by automatic mechanism as follows. The lifting belt h is coupled to a pin p oil the loose crank o. To the further end of the pin p is connected, eccentrically, one end of the brake band n, surrounding the continuously revolving pulley m, and on the near end of the pin p is mounted a brake-operating lever u. To start the hammer, the lever v is depressed, thus raising a rod w the end of which engages a slot in a loose disk x, coupled to another disk x<2> on which is a cam face x<1>. This engages the roller u<1> on the lever u, and actuates the brake band, so that the crank and all its attachments are rotated, and the trip i is raised. The disks x, x<2> are carried round by a friction band y attached to the crank p, until their motion is arrested by an adjustable stop z, on a fixed disk z<2>. The arm u is thus released from the cam x<1>, the brake band n relaxed, and the trip i falls. When the end of the slot in the disk x again engages the rod w, the disks x, x<2> are arrested, and the further movement of the crank o causes the re-engagement of the lever u and cam x<1>, thus raising the trip again.
