Title: Improvements in or relating to the separation of coal and like materials
IPC: B03B5/62
Filed: 1934-08-01
Abstract: 443,837. Separating coal and shale. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WOOD, H. L., Fraser & Chalmers Engineering Works, Erith, Kent. Aug. 1, 1934, No. 22456. [Class 82 (ii)] Fine particles of coal are separated from fine particles of shale by introducing the mixture into water which is agitated, for example by an upward current of water, so that some of the fine shale particles are maintained in suspension and form a fluid mass on which the coal floats, the agitation being insufficient to carry the small particles of shale away with the floated coal. The separation may be carried out in a tank 1 provided with a feed launder 2, a discharge weir 3, and a refuse outlet 4. The water in the tank is agitated by an upward flow produced by downwardly directed jets of water issuing from horizontal pipes 11 located beneath a sloping screen 10 forming the bottom of the tank. The pipes are arranged in a box 14 which is packed with gravel and provided with partitions 15 separating the pipes. The water supply to each pipe is independently controlled. The height of the weir 3 and the size of the refuse opening 4, which leads to a refuse extractor 17, can be adjusted by sliding plates 6 and 8 respectively. The velocity of the upward current is adjusted so that the small shale particles form a fluid mass extending up to just below the weir 3 ; the coal floats on this fluid mass and passes over the weir. The height of the fluid mass is controlled by varying the upward current and by varying the rate at which shale is removed through the outlet 4. The material treated may be fine material separated from coal prior to treatment by the sand-flotation process, the washed fine coal obtained being mixed with the coarser coal separated by sand-flotation. The Provisional Specification states that ores and like materials may also be treated. Specifications 119,038, [Class 82 (ii)], and 403,150 are referred to.

Abstract: 1,105,938. Removing superfluous water from roofs. WATEIS Ltd. 26. May, 1966, [26, May, 1965], No. 22465/65. Heading E1S. Superfluous water is removed from a roof covering by pumps attached to pipes which extend through the top waterproof layer to water-permeable material of the covering. Each pipe has perforated walls and extends through an asphalt, a felt and a screed layer and engages the concrete of the roof and extracts water from the screed and the concrete. A perforated box filled with shingle surrounds the pipe. In a modification each pipe rests on a screed layer impermeable to water and is secured to an annular metal sheet by nuts screwed on the pipe. This metal sheet supports the felt and asphalt layer in such a position that these layers are locally held above the screed to form a space and water is extracted from the felt. The pipes are eventually removed.

Filed: 1927-09-05
Abstract: 305,552. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 5, 1927. Mineral waxes, purifying &c.-Crude or d,eresinified montan wax is bleached and largely hydrolysed by treatment at 100-130‹ C. with a compound of high-valent chromium and with at least 500 per cent of a 30-70 per cent aqueous solution of a mineral acid. The products are much more readily saponified or emulsified than the original wax, and consist largely of acids obtained by hydrolysis of the wax esters and by oxidation of the alcohols. In an example, 100 kilograms of montain wax are emulsified by stirring in 1200 litres of 50 per cent sulphuric acid or 66 per cent phosphoric acid. 160 grams of CrO3 as a concentrated aqueous solution, with or without mineral acid, are run in slowly, and the temperature raised to boiling. Steam is allowed to escape slowly, so that at the end of 5 hours the temperature reaches 120‹ C. The mixture is allowed to stand and cool, when the bleached wax and wax acids form an upper layer. Specifications 289,621, 299,133 and 303,036 are referred to.
