Title: Improvements in the treatment of coal distillation gases
IPC: C10K1/08
Filed: 1927-10-17
Abstract: 304,345. Imperial Chemical Industries, Ltd., Gordon, K., and Hughes, J. Oct. 17, 1927. Materials for purifying ; washing processes.- Coal distillation gases are washed with water and scrubbed with oil to remove tar, ammonia and benzene and the clean gas compressed preferably to 250 atmospheres. Carbon dioxide, hydrogen sulphide and sulphur compounds are removed by ammonia liquor and the gas is then treated in a tower with, an ammoniacal cuprous salt e.g. formate, acetate or carbonate, practically all the carbon monoxide and unsaturated hydrocarbons (principally ethylene) being absorbed. The gas is now washed with a high-boiling solvent e.g. kerosene to remove most of the methane as described in Specification 293,138, [Class 1 (i), Chemical processes &c.], and after the addition of gases to adjust the ratio of hydrogen to nitrogen to 3 :1 the mixture is employed for the synthesis of ammonia. The liquor resulting from the first treatment may be utilized in making ammonium sulphate from gypsum and ammonium carbonate. The gases driven off from the second washing solution by heat may be treated under pressure with silver nitrate solution which absorbs ethylene, as described in Specification 291,186, [Class 1 (i), Chemical processes &c.]. The remaining gas, mainly carbon monoxide, may be utilized in the manufacture of formates, formamide, hydrogen or carbon. The ethylene may be recovered by heating or reducing the pressure and utilized in making ethylene glycol, ethyl alcohol or ethylene dichloride. A gas consisting of about 80 per cent of methane is recovered from the third washing liquid and may be passed through an electric arc to form acetylene which is removable by a solution of mercurous sulphate in sulphuric acid and the residual gas may be recirculated through the arc or burnt to supply heat to the coke ovens. In modifications the gas may be subjected to increasing pressures for the successive washings, or the first two steps may be effected at 50 atmospheres, the final stage requiring, however, about 250 atmospheres. The sulphur compounds may be removed by the dry iron oxide process before the washing treatment.

Filed: 1922-10-11
Abstract: 203,213. Kleffel, H. E. Oct. 11, 1922. Grates.-A combined travelling grate and underfeed mechanical stoker constructed to provide movable retorts has a plurality of endless moving tuyÞres and endless moving retort bottoms arranged alternately, the sides of the retorts being the adjacent tuyeres. Fuel carriers move with the retort bottoms. A fuel hopper 13 has an extension 16 at the delivery end and a slide 18 adjustable by rack and pinion. A shaft 22 which may be driven at a variable rate by a motor and reduction gears carries a series of sprocket wheels 23 connected by chains 28, Fig. 4, to sprocket wheels 27 on a shaft 25. The chains 28 in pairs support the pintles 29, Fig 6, of the tuyeres, which are built up in sections by plates 33 dovetailed in recesses 31 and by end plates 34, 35. The tension of the chains 28 may be adjusted automatically by mounting the shaft 22 in blocks 38, Fig. 3, acted on by springs 40 which may be set by means of a screw 41. A similar adjustment serves for the horizontal adjustment of a shaft 44 which transmits motion to the retort bottoms 58 and fuel carriers 59. The shaft 44 is adjusted vertically by a hand wheel 54 or by power, through the medium of bevel and worm gearing and a screw 49. The shaft 44 carries sprocket wheels 57 connected by chains to sprocket wheels on the shaft 25, the chains carrying brackets detachably connected to the retort bottoms 58. Brackets on which the fuel carriers 59 are pivoted are also arranged between the chains. The retort bottoms are removable and renewable. Guide rails 67 are provided for control of the position of the fuel carriers with respect to the retort bottom, by, for example, mounting them on frames hung on the shaft 22. The guide rails are inclined rearwardly so that the carrying faces of the fuel carriers are lowered as they approach the rear end of the grate. The thickness of the fuel bed is increased or diminished by speeding up or diminishing the speed of the retorts with respect to the tuyÞres. Partitions and dampers may be placed to direct the forced draught to correspond to the thickened fuel bed.

Title: Improvements in or relating to devices for automatically igniting gas burners by theactuation of valve mechanism controlling the flow of gas
Inventor: BRADLEY JAMES ALBERT
IPC: F24C3/10
Filed: 1961-07-28
Abstract: 945,965. Gas burners. GAS COUNCIL. July 30, 1962 [July 28, 1961], No. 27580/61. Heading F4T. [Also in Division F2] In a gas cooker having flash tubes communicating an ignition combustion chamber with the main burners, a gas valve mechanism comprises means for limiting the rate of gas flow to the burners until the flow of gas has been initiated to the chamber containing an electric ignition element. The limiting means comprises a conical plug valve 12 rotatably mounted in a conical casing 10 which has a gas inlet port 14 at right angles to an outlet port 17 in a threaded socket 18 for communication with the igniter. A threaded outlet port 13 is provided for connection to a burner tube. The plug valve 12 has a stepped bore 22, 23, 24 and an arcuate shaped inlet port 29 approximately at right angles to an outlet port 30. A ball 26 in the bore 22 is urged on to a seat by a compression spring 32 and is actuated by the head 28 of a push rod 27 loosely accommodated in the bore 24. The lower end of the rod 27 engages a manipulating spindle 34 provided with projections 41 which slidably engage axial slots 42 in a tubular extension 43 of the plug valve 12. The spindle has a further projection 45 which operates in two arcuate recesses in a front plate 38, in communication with each other via an arcuate recess in a back plate 37. The plates 37, 38 and a gasket 40 are screwed to a flange 20 on the casing 10 and hold a compression spring 44 in abutment with the plug valve 12. A further compression spring 47 encircles the stem 27 between the spindle 34 and the plug 12. The flash tubes may be adapted to communicate with a pilot jet controlled by the valve mechanism. The arcuate recesses may extend to the edge of the plates 37, 38 to allow the position of the projection 45 to be seen. In operation, the spindle 34 is given limited rotation from an " off " position, as permitted by the first recess in the front plate 38, to partially communicate the inlet ports 14 and 29, and to completely communicate the outlet ports 17 and 30. The spindle is then axially depressed to open the ball valve thus supplying gas to the ignition chamber and the projection enters the recess in the plate 37. After further rotation, the spindle is axially raised and the projection enters the second recess in the plate 38 whence the ball valve is closed and further rotation increases the gas supply to the burners. In an alternative arrangement, a fixed ported housing accommodates a rotatable element having ports positioned to give the desired gas supply sequence upon rotation. These two elements may be in the form of discs. At the limited gas supply stage, a dwell is provided by either a spring controlled detent or a change from rotational to axial movement of the movable element.
