Patent GB-980952-A (GB)
Title: Improvements in or relating to methods of cleaning gases
IPC: B01D50/00
Filed: 1961-04-17
Abstract: A method of removing droplets, mist and dust particles from a gas-vapour mixture, e.g. one produced by the gasification of liquid and/or solid fuels with an oxygen-containing gas, comprises cooling the gas to below the dew point of contained hydrocarbons, e.g. to 15 DEG  C. at 20 atmos. gauge, separating condensate and dust from the gas in a conventional separator, heating the gas through 20 DEG  to 50 DEG  C. at constant pressure, e.g. indirectly by heat exchange and removing remaining condensates and dust in a second separation stage. The separators may be conventional impingement apparatus and/or filter beds of catalytic or surface-active agents, and the heating stage should be so controlled that higher boiling hydrocarbons do not have time to evaporate, and may thus be removed in the second stage. Lower boiling hydrocarbons are evaporated and pass through the apparatus to subsequent process stages, e.g. for carbon monoxide conversion with entrained steam. The method is intended to prevent corrosion and incrustation of heat exchangers &c. through which the gas is to be passed, by liquids which, due to initial undercooling, escaped the first separator.  In an example, a crude gas containing inter alia H2, CO2, and CO is cooled to 180 DEG  C. by trickling water to remove tar and dust, passage through the first separator removing mist and more dust.  The partly cleaned gas is heated to 210 DEG  C. and passed through the second separator to remove further liquids and dust, and then heated to 350 DEG  C. for CO conversion. The hot converted gas provides the heat both heating the cleaned gas for conversion and for the heating stage.

Patent GB-237875-A (GB)
IPC: C05B9/00
Filed: 1925-05-27
Abstract: A fertilizer containing tri-magnesium phosphate, a magnesium-calcium phosphate, or an alkali-magnesium-calcium phosphate is obtained by heating to about 900-1100 DEG  C. in an atmosphere containing water vapour, a mixture of a natural calcium phosphate with magnesium chloride or sulphate with or without an alkali salt and with enough silica to form calcium orthosilicate with the calcium displaced by the magnesium and alkali metal. When iron or aluminium is present, the amount of silica may be reduced as calcium ferrite or aluminate are then formed, and silica may be omitted when enough is present in the raw phosphate. A suitable mixture may be made of the magnesium salt with phosphates too poor and too rich in silica, but if too much silica is present, lime must be added to combine with the excess. The atmosphere containing water vapour may be provided by admitting steam to the heating-chamber or by direct heating with a fuel containing hydrogen or by both methods.  Specification 23634/07 is referred to.

Abstract: 603,446. Automatic control of temperature. AIR REDUCTION CO., Inc. June 7, 1945, No. 14442. Convention date, June 14, 1944. [Class 38 (iv)] [Also in Groups II and XL (b)] Thin work-pieces, e.g. pipes or tubes, of a ferrous metal that is hardenable by heating and quenching are heat treated by directing heating flames against one surface of the workpiece to heat the metal above its critical temperature, effecting relative movement behind the flames and the work piece so that the latter is heated progressively, quickly quenching the heated metal by projecting fluid against the opposite surface of the work piece and adjusting the rate of relative movement between the flames and the work piece in accordance with the heat condition of the metal existing at the opposite side of the work-piece. As applied to the heat treatment of a pipe 12, the latter supported on a roller 11 is moved progressively past a torch or heating unit 14 having spaced openings 15 which direct a ring of flame against the inner surface 16 of the tube, by pairs of rollers 21 fitting the pipe and driven by shaft 22 from a shaft 23 having inner gears 24, 25 and driven by a motor 26 having a field winding 27. The latter is connected by wires 32 to an automatic control device 31 which maybe a heat or light sensitive current controller of known type and is responsive to heat energy radiated from the pipe 12. A cooling ring 35 supplied with fluid from a pipe 38 prevents the spread of heat rearwardly along the pipe and a quenching pipe 36 supplied from a pipe 37 is provided for cooling the heated part of the pipe after it has passed the device 31.

[Class 83 (iii)] [Also in Group XXIV] A gear generating machine, having a rackform cutter C, comprises means for rolling the work-piece W along the cutter which include a rotatable and translatively movable work-holder 22, an angularlymovable former 27 simultaneously translatable with the work-holder, an abutment 28 co-operating with the former to limit its angular movements in proportion to its translative movements, and torquetransmitting means between the former and work-holder which cause the rotational movements of the work-holder to be larger in angular extent than those of the former occurring at the same time. The cutter C, Figs. 6 and 7, is mounted on a slide 23 reciprocated along a guide-block 64, pivoted to the bed 20 at 66, by an adjustable-throw crank 71, a bell-crank 74, 75, and a connecting link 76. A cam and follower 83, 84 raise the guideblock against a stop 67 to bring the cutter into working position and the cutter is released by gravity. The bell-crank arms are adjustably connected at 80 to vary the stroke of the cutter. The complete cutter-operating mechanism is carried on a sliding table 61 having slight play in its side-guides by which it is clamped in position. A guide-bar 96, pivoted to the bed 20, passes through a slot in the table 61, play being taken up by a tapered gib adjusted by a screw 99. To set the cutter to its correct horizontal position and height, the side-guides are unclamped, the table is raised by a screw 89 and the guide-bar 96 is adjusted angularly by screws 101. The work W, Figs. 4 and 6, is mounted on a shaft 22 carried on a slide 21 reciprocated by a screw 26. A constant-torque electric motor 52 drives the shaft 22, which also carries a gear 57 to rotate the former 27 through change-gearing. The former 27 is detachably secured to an annular gear,59 and co-operates with adjustable abutments 28, 29 fixed to the bed 20. The screw 26 is driven from an electric motor 31, through change-gearing, and is reversed by a clutch 45 operated by a solenoid 120 through a yoke 126. The motor 52 is reversed and the solenoid 120 energized by switches 128-131, Figs. 15 and 16, actuated by stops 135. The stops are carried on a shaft 134 oscillated by gears 136, 137 in time with the former 27; they are adjusted by knobs 142, 145 controlling pinions 141 meshing with face-gears 140 formed on sleeves 138, 139 which carry the stops, after first slackening clamping wedges 146. The gear may be finished after one or more traverses and the stops may be arranged to stop the work-slide after one or two traverses. It is stated that the machine may be hydraulically or mechanically operated.
