Patent GB-337458-A (GB)
Title: Improvements in or relating to the concentration of minerals including coal
IPC: B03B4/00
Filed: 1929-08-02
Abstract: 337,458. Friend, J. F. C. Aug. 2, 1920. Pneumatic separating.-In the separation of materials of different density, such as in the cleaning of coal, of the kind in which the materials are fed in a substantially thick layer over a surface perforated for the passage of air and are simultaneously subjected to the action of pulsating currents of air so that the materials become arranged in layers of different density which are separately discharged, the pulsations are produced by means which cause alternate positive, and minus pressures and the feed movements are intermittent and occur during the periods of minus pressure. In the embodiment of the invention described, the apparatus consists of a substantially horizontal deck 11 of perforated material with upstanding sides 12 and forming the upper part of a box 23 which constitutes the air chest. The lower end of the box is formed as a piston 24 which is connected to the main portion by an air-tight flexible bellows 25 and is reciprocated vertically by a cam 26 on a shaft 27. The deck and air-chest are mounted on links 17, 20, and are given a horizontal jigging' movement by the cam 13 and spring 22 to cause the material, which is fed to the deck from the hopper 50, to move along the table intermittently, and the cam shafts are timed so that, the movements of the material synchronize with the suction stroke of the piston 24. Preferably the cam 26 is formed to cause the piston to dwell at the end of its compression stroke, and a series of lift valves 74 may be actuated by a cain 77 to admit air under pressure to the air chest in sufficient amount to make up for the loss due to leakage. At one or more places, transverse gaps 59, 62, and weirs 58, 61, are provided for the discharge of the stratified layers, each of the gaps being associated with rotary valves 60, 63 and discharge conveyers 64, 65. The final upper layer is discharged over the weir 58 to the shoot 80. A screw conveyer 32 is provided in a channel of the piston plate 24 to discharge the fine material that passes through the deck. Preferably the conveyer is in two parts working to opposite ends for grading this fine material and the air chest is divided into two corresponding parts by boards 36, 37 and a flexible bellows 38. The conveyer is rotated in its normal up and down movements by a ratchet wheel 34 coacting with a stationary pawl 35. In one modification the piston may be dispensed with and the air chest connected to one end of a U-shaped tank containing water which is pulsated by compressed air or a piston. In further modifications, the air chest may be connected to positive and minus air pressure mains by valves which are opened and closed alternately, or a diaphragm connected to the air-chest by an air trunk may be oscillated by intermittent air pressure applied to the outer side. Specifications 4755/91 and 6337/96 are referred to.

Abstract: 1,060,962. Once through vapour generators. BABCOCK & WILCOX CO. June 4, 1965 [June 5, 1964], No. 23925/65. Heading F4A. A once through forced flow vapour generating, superheating and reheating unit comprises a vertically elongated pressure vessel 12 having a bank of helically coiled vapour generating tubes 98 supported by steel grid 134, extending upwardly from a feed water inlet 48 and water inlet tubes 74, 100, to four equi-spaced steam outlet chambers 102. The steam formed passes to four equi-spaced superheater inlet chambers 110 to pass through helically coiled superheater U-tubes 112, supported from brackets 118, contained in an annular pass between the casing of the vessel 12 and a depending baffle 116 also supported by brackets 118, to exit through four equi-spaced superheater outlet chambers 122 to the point of use. Steam for reheating enters through four equi-spaced reheater inlet chambers 124 to pass through the helically coiled reheater U-tubes 128 supported by steel grid 136 and located in the parallel annular pass defined by the baffle 116 and an escape tube assembly 78, to exit through the four heated outlet chambers 132 to a further point of use. Liquid sodium is supplied through superheater inlet conduit 142 and reheater inlet conduit 140 to respective ring main distribution systems 154-158 and 148-152 to heat the superheater and reheater tube banks 112, 128 respectively, the liquid metal from both passes combining to heat the vapour generating tube bank 98 on its way to the liquid sodium outlet 70. The metal is normally maintained in the vessel 12 at a level 160. The escape tube assembly 78 constructed in sections 80, 82, 84 provided with a rupture disc 166 at the top provides relief means for gases generated due to possible interaction of the sodium and water. The vessel 12 is constructed from five wall sections 20, 22, 24, 26, 28 and upper and lower closure heads 30, 14 all bolted together to facilitate dismantling and reassembly. Cylindrical liners 32, 34, 36 adjacent these sections define annular spaces 38, 40, 42 forming protective argon or stagnant liquid metal jackets to protect the shell from thermal stresses. On dismantling of the unit after drainage, the upper closure head 30, the heating fluid distribution system piping and section 80 of escape tube assembly 78 may be removed as a first unit. The fifth wall section 28 and the reheater tube bank 128 may be removed as a second unit; the fourth wall section 26, the superheating tube bank 112, the baffle 116 and the supporting brackets 118 all together as a third unit; the third wall section 24 and section 82 of escape tube assembly 78 as a fourth unit; and the second wall section 22, the vapour generating tube bank 98, the feed water inlet tubes 74, 100, tube sheet 52 and section 84 of escape tube assembly 78 as a fifth unit, leaving only the first wall section 20 and lower closure member 14 remaining.
