Title: Method and apparatus for treating materials
IPC: B01J8/18
Filed: 1947-08-21
Abstract: <PICT:0658742/III/1> <PICT:0658742/III/2> In effecting chemical reactions which involve an elastic fluid and in which a non-gaseous catalyst is used, particles of the latter are suspended in the elastic fluid and circulated in a closed path in a container, the suspension being intensely agitated by a high-velocity (i.e. equal to that of sound) jet so that the surfaces of the catalyst particles are renewed or cleaned by mutual impact.  Part of the suspension may be withdrawn, the remainder being recirculated.  The part of the suspension withdrawn may be introduced to a second closed path from which part is withdrawn and in which the remainder is recirculated and so on.  Such reactions may be the production of hydrocarbons for synthetic petroleum by catalytic reaction between hydrogen and carbon monoxide; the catalytic cracking of hydrocarbons; the controlled oxidation of hydrocarbons and alcohols to aldehydes, ketones, acids, &c.  In an embodiment, an upright stack 2, Fig. 1, forms part of a loop constituted by tubes 4, 6 and 8 and is fed with material in finely-divided form from hopper 38 by means of the low-pressure blower 34 and with high-pressure gas or vapour through nozzles 30. The particles circulate round the loop, centrifugal action allowing only the finest particles to escape via outlet 10 into the succeeding loop 12, 14, 16, and from that loop via outlet 18 into the next loop 20, 22, 24.  Particles may be removed from each loop, for example heavier particles through outlets 58, Fig. 2, disposed on the outside of a curve, or lighter particles through outlets on the inside; and particles, particularly of liquid or semi-solid material, which have collected at the bottom of a loop may be redispersed by high-pressure nozzles provided there.  Gas or particle bleeds or gas or particle feeds may be provided in any of the loops.  The vapours finally leaving at outlet 28 may pass to a separator for removing fines and to a condenser.  Various ways of connecting the loops are illustrated and described so, for example, that most of the gas molecules in each loop recirculate a very large number of times or, alternatively, no more than a relatively small number of times.  The loops may be fitted with heating or cooling jackets, Fig. 8 (not shown).  Solid particles may be ground as a result of the circulation, for example to micron sizes.  In a further type of apparatus, Fig. 10, <PICT:0658742/III/3> the loops are replaced by cylindrical drums 188, 194, 200 with central baffles 190, 196, 202 shielding the inlets 210, 234, 242 from the respective outlets 192, 198, 204.

The machine described is of the general character of that described in Specification 25040/08, [Class 17, Boots &c.]. The wire is fed by a feed-roller 1 and presser roll 11 through a groove 33 in a lever 20 to a shearing die 42. 43 and a transferring die 44, 45. The roll 1 is rotated intermittently by a cam-operated lever 7 and pawls 4. The lever 20 is pivoted upon a shaft 21 and its end 19 is adjustably supported by an eccentric part of a shaft 22. The die 44, 45 is mounted upon a block 35 which is adapted to be turned through 90‹, by means of levers 61, 62, rack and pinion 66, 65, and cam lever 67, in order to shear the wire and present the severed slug vertically beneath the driver (not shown). A second camlever 10 is arranged to assist this turning action during its early stages, when the slug is being severed. Should a slug be not fully driven into the work and be carried back by the transferring die during its return movement it will engage the shearing die or the end 19 of the lever 20, whereby the latter is turned about its pivot 21 against the action of spring plungers 24, 26, so that its other end 32 engages a stop 34 on the lever 12 which supports the presser roll 11, turning this lever about its pivot 13 against the action of a spring 14, and thereby interrupting the wire feed. The shearing and transferring dies are each made in two parts and are releasably and adjustably clamped in their respective carriers 20, 35. In order to set the shearing die accurately in the lever 20 the latter may be removed from the shaft 21 and mounted temporarily upon a shaft 54, when the die may be adjusted against a gauge face 57.

Abstract: 1,187,159. Granulating metal. AIR REDUCTION CO. Inc. May 17, 1968 [May 25, 1967] , No.23569/68. Heading C7X. In a continuous method of directly converting molten metal to powder having a low oxygen content, a steam of molten metal 4 is directed into a substantially enclosed chamber 7 through an opening 29 in the chamber, a cooling liquid having a vapour that does not oxidize the metal is directed at high velocity through the opening 29 into confluence inside the chamber 7 with the stream 4 of molten metal thus quenching and comminuting the metal to form powder, vapour generated in the quenching of the metal is confined in the chamber 7 to maintain therein an ambient atmosphere of the vapour at a substantially constant pressure slightly above atmospheric, and the powder is collected in a cooling medium 37 immediately after it has passed through the said atmosphere. In Fig. 1, molten iron 2 from a ceramic-lined tundish passes through nozzle 3 in stream 4, which stream passes through a V-shaped trough of high-velocity cooling water provided by nozzles 20 and 22 Fig. 2, the ends of the trough being closed by sprayed screens of cooling water from jets 21 and 23, which intersect below the level 31 of the apex of the trough formed by the two main jets 20 and 22. A baffle 28 is provided such that the said level 31 is below the level of the baffle and cylindrical wall 35 together with water level 36, which is controlled by a weir as shown constitutes a substantially enclosed chamber 7 which becomes filled with steam due to the heating effect of the metal being quenched. The metal powder is collected at 43. The said enclosed space is maintained at a pressure slightly above atmospheric, and when pressure build-up forces the level 36 of water in cylinder 35 far enough down for steam to escape under the edge thereof, the steam is vented. Other means of pressure control are described.
