Title: Improvements in machines for separating liquid from reduced ore products and the like
IPC: B04B1/12
Filed: 1934-11-12
Abstract: 445,722. Centrifugal machines. KEET, G. C. E., 15, Simmonds Street, Johannesburg, South Africa. Nov. 12, 1934, No. 32531. [Class 23] Liquid is separated from reduced auriferous ores and the like in a rotating vessel with peripheral discharge outlets for the separated solids and with an inner rotatable element, eccentrically mounted, which forces the solids through the discharge outlets against the action of pressureclosed valves. The rotating vessel or pan has upper and lower parts 14, 15 with a cylindrical wall 16 connecting them. The central portion of the top part 14 is raised to form a lip 51 over which liquid discharges into the chamber 52 with a discharge pipe 55. The lower part 15 forms an extension of the boss 21 and the part just outside the bearings is sunk to form a well 49. A thick rubber ring 38 is arranged at the cylindrical wall 16 and discharge openings 57 are provided. They are normally closed by valves 59, the stems 60 of which are connected to flexible diaphragms 65 on the inside of an annular casing 64. Fluid is introduced into this casing through the pipe 71 and its pressure is varied by means of a diaphragm 93 subject to controlled spring pressure in the external face of the casing. The inner element 39 is hollow and has an opening 40 in the centre of its lower face ; it is rotated by the frictional engagement of the material passing through the vessel 14, 15. Partitions 83 of rubber, or similar material, are held in slots in the vessel 14, 15 and project on to the surfaces of the element 39 thus forming a number of passages in the space between the two rotating members. The stationary shaft has three parts 1, 2, 3 offset with respect to each other, and the inner element 39 is mounted upon an eccentric sleeve 45 on the top part 3 of the shaft. The sleeve 45 can be rotated to vary the eccentricity of the element and then locked in position. The material is supplied by the shoot 79, it passes through the ducts 77, 78 in the stationary shaft, to the inside of the element 39. It then passes to the outer vessel 14, 15 where the solids fill the passages 57 in the rubber ring 38 and the liquid is discharged over the lip 51. When the passages 57 are packed, the rotation of the eccentric element 39 forces solid material past the valves 59 into the receiver 76. A flanged cap 27 protects the bearing 24, and when the machine stops a pipe 80 allows the contents to be discharged until the level is below the bearing 24.

Title: Process for the preparation of hydrocarbon oils having a reduced content of gum-forming components
IPC: C10G31/06
Filed: 1952-12-29
Abstract: Hydrocarbon oils having a reduced content of gum-forming components and of sulphur compounds are prepared by heating the oil at 75-125 DEG  C. in the presence of oxygen, further heating the oil at at least 140 DEG  C. without any further supply of oxygen, and separating the liquid polymers thus formed.  The oils may be treated with free oxygen or air, or ozonised oxygen or air; they may be treated under pressure and under the influence of ultra-violet light. Part of the oil treated in the first stage may be recycled, or alternatively a small quantity of peroxide may be added to the oil in this stage.  The oils may be separated from the liquid polymers by distillation or by contacting with an adsorbent such as clay, bauxite, silica gel or Fuller's earth. Preferably before separation of the polymers, the oils may be freed from aldehydes and ketones by washing with a saturated aqueous solution of sodium bisulphite and then treated with an alkali metal hydroxide solution to remove acid components.  Oils treated may be gasolines obtained by reforming or thermal or catalytic cracking of hydrocarbons or hydrocarbon mixtures, shale oils or lignite tar oils; mixtures of a cracked and straight-run distillate may also be used.  The examples refer to treatment of a cracked gasolines obtained by thermally cracking solid paraffin wax, and by catalytic cracking of gas oil. Para-phenylene diamine may be added to the treated oil.  In a modification, a hydrocarbon oil containing peroxides obtained by heating in the presence of oxygen at 75-125 DEG  C. may be mixed with another portion of the same oil or with a different oil at at least 140 DEG C. to remove the gum-forming components therefrom.
