Filed: 1951-08-30
Abstract: 718,187. Washing granular materials. NATIONAL COAL BOARD, and HIRST, A. A. Dec. 1, 1952 [Aug. 30, 1951], No. 20491/51. Class 82 (2) [Also in Group XXIX] A jigging device for coal &c. washing comprises a conventional machine having a grid 5 on which the raw material separates into a a coal layer 6 and a refuse layer 7, the latter being withdrawn in a known manner by the refuse extractor 17. A tube 8 is connected to the jig below the grid 5 and a pulsating column of water is set up in the tube, the amplitude of the pulsations varying inversely as the thickness of the bed above the grid. The pulsating column of water in tube 8 acts as a piston drawing air in at 9 and driving it out at 10, the two latter being one-way check valves and the whole assembly acting as a variable stroke pump. The air pressure which builds up is. relieved by a leak 12 which is adjustable and the air pressure is recorded on a manometer 23 and/or enters a bell 13 which rises or falls with the variation of mean pressure caused by the variation of the piston amplitude in the tube. The position of the bell thus varies with the thickness of the bed on the grid and the movement of the bell due to a change of thickness of the bed controlls the discharge device, either directly or through relay apparatus, to keep the bed thickness uniform. The variable leak comprises a conduit 11, being the discharge pipe from the pump, terminating in casing 37 having a rod 38 with a tapered recess 39 of triangular section. The rod 38 is rigid with and supported by a plate 43 which slides on rods 42. The vertical position of this plate is controlled by a wheel 44 on the secured part of the rod 38 after lock-nuts 47, 48 are released and thus the rod 38 is moved into or out of the bush 40 thus varying the size of the leak.

Title: Improvements in and relating to the manufacture of paraffins
IPC: C10G73/42
Filed: 1961-06-08
Abstract: Paraffins having a melting point between 20 DEG C. and 48 DEG C., and being of substantially iso- and/or cycloparaffinic structure, are obtained from waxy distillates, having a viscosity between 3 and 9 centistokes at 100 DEG C., and derived from distillation of crude petroleum of paraffinic or mixed base nature by a process comprising the steps of fractionating the waxy distillate by successive solvent dewaxing treatments into a normal paraffinic fraction, an oily fraction, and an iso- and/or cycloparaffinic slack wax substantially free from n-paraffinic constituents, but still retaining 10-40% by weight of oily constituents, and subjecting said slack wax to a sweating operation so as to remove substantially all the oily constituents retained therein.  The starting waxy distillate may if desired be refined by conventional furfural or phenol refining treatments, as in the manufacture of lubricating oils, prior to subjecting it to the above fractionation.  In one method the waxy distillate is first solvent dewaxed at -25 DEG  to -35 DEG C. to obtain a waxy and an oily fraction, and the waxy fraction is further solvent extracted at -15 DEG  to +15 DEG C. to separate an n-paraffinic fraction from an iso- and/or cycloparaffinic slack wax. In another method the waxy distillate is first solvent dewaxed at -15 DEG  to +15 DEG C. to separate the n-paraffinic fraction, and the remainder is then solvent dewaxed at -25 DEG  to -35 DEG C. to separate an oily fraction and an iso- and/or cycloparaffinic slack wax fraction.  Suitable solvents for use in the process include:-ketones, aromatic hydrocarbons, chlorinated derivatives, &c. In examples a mixture of aromatic hydrocarbons with methylethyl ketone is employed.  The cyclo- and/or isoparaffins obtained by the above process may be mixed with other paraffins to modify their properties.
