Title: Improvements relating to the production of ferric chloride from iron ore
Inventor: REEVE LEWIS
IPC: C01G49/10
Filed: 1952-01-01
Abstract: <PICT:0734081/III/1> Ferric chloride is obtained from iron ore or other material containing ferric oxide by treating the material with hydrochloric acid and then distilling off ferric chloride, preferably from a fluidized refractory bed, in the presence of sufficient hydrogen chloride to prevent hydrolysis.  In the process illustrated, low-grade iron ore which may contain calcium, magnesium, aluminium, and phosphorus is roasted if necessary to convert the iron to the ferric state and is then dissolved in hydrochloric acid in vessel 1. The solution is filtered to remove insoluble matter at 2, concentrated in an evaporator 4, and passed to the first stage 6 of a two-stage distillation apparatus 5 supplied with a hot refractory material which is fluidized by admission of hydrogen chloride at 8. Most of the water is distilled off in this stage at 100-200 DEG  C.; the refractory material with the salts deposited thereon then passes to stage 7 and is fluidized by hot hydrogen chloride admitted at 10, the temperature being maintained at 200-400 DEG  C.  The distilled ferric chloride is removed at 11 and the refractory is reheated in vessel 13 by treatment with hot combustion gases, and may be treated with steam to recover hydrogen chloride from the deposited chlorides as described in Specification 734,080.  Alternatively the material leaving 7 may be leached with water to recover the salts. Aluminium present in the ore may be precipitated as hydrated aluminium chloride by allowing the solution to settle before distillation. Specification 701,797 also is referred to.

Title: Process for the catalytic oxidation of olefins in the presence of cuprous oxide to form unsaturated aldehydes and ketones and the aldehydes and ketones so formed
Filed: 1950-01-10
Abstract: In the production of unsaturated aldehydes or ketones by oxidation of olefins of at least 3 carbon atoms in the vapour phase in the presence of a cuprous oxide catalyst with recycling of unreacted material, the carbon monoxide content of the recycled material is reduced to maintain the content of the mixture fed to the catalyst at below that at which substantial decrease in catalytic activity results.  Carbon monoxide is formed as a by-product and builds up under cyclic conditions of operation.  It is removed to give a content of less than 0.5, preferably less than 0.2 per cent by volume, in the reaction mixture.  Where the fresh feed has a carbon monoxide content in excess of this figure, it is necessary to reduce it prior to reaction.  The olefins specified range from propylene to octenes, and include cyclo-olefins, and homologues and substitution derivatives thereof.  Propylene may be converted to acrolein, isobutylene to methacrolein, a - or b -butylene to methyl vinyl ketone, 1- or 2-pentene to ethyl vinyl ketone and/or 3-pentene-2-one, 2 - methyl - 2 - butene to methyl isopropenyl ketone, and cyclopentene to 2-cyclopentene-1-one.  The cuprous oxide is preferably used with a carrier such as silica gel, silicon carbide or pumice and may be in fluidized form.  Reaction temperatures are about 200-450 DEG  or up to 600 DEG  C., and apparent contact times about 0.1-10 seconds. Molar ratio of olefin to oxygen is from about 1 : 1 to 30 : 1, and diluents such as steam or nitrogen may be present. After separation of the carbonylic product, the unreacted olefin may be scrubbed with a selective solvent such as kerosene, gasoline, an ester or ketone, the unabsorbed gases vented, and the olefin stripped from the solution and recycled.  Alternatively, the olefin, after adding further oxygen if required, is passed over a catalyst promoting selective oxidation of CO to CO2, e.g. "Hopcalite" catalysts comprising MnO2, Cu2O and, if desired, CO2O3 and Ag2O.  The CO2 may be returned with the olefin or removed with alkali. Oxidation of the CO with steam in the presence of iron oxide, reduction with hydrogen in the presence of Ni, Co, Pt or Fe, and rmeoval by an adsorbent or absorbent, e.g. acidic cuprous chloride solution, are other methods referred to.  Specification 640,383 is referred to.

Abstract: 850,107. Centrifugal separators; pneumatic separating. MASCHINENFABRIK HARTMANN A.G. Jan. 8, 1958 [Jan. 10, 1957(2)], No. 724/58. Classes 23 and 117 A stream of granular material in air is fed at 7 to a centrifugal chamber 1 and passes down the wall thereof to a classifying chamber 2, and on leaving the wall of the latter it is acted upon by an air stream which is fed downwardly through a tube 6 and passes upwardly between an axially adjustable cone 5 and a wall 4. The finer particles are carried upwardly and away with the main air stream and the remainder fall downwardly to an outlet 11. In a modification the granular material leaves the wall of the classifying chamber at a point below the upper edge of the cone. In Fig. 3, the part 102 of the wall of the centrifugal chamber 101 is porous and an air stream passes through it to act upon the downwardly flowing material. Alternatively the porous wall may be located at 121. The pores of the wall may be arranged radially or tangentially in the same direction as the main feed; different sections of the porous wall may be penetrated by air streams of different pressures or at different angles.

Abstract: 746,759. Animal and wheeled toys. BRIEN, R., and DEAN'S RAG BOOK CO., Ltd. Jan. 11, 1954 [Jan. 9, 1953], No. 765/53. Classes 132(1) and 132(3) A toy wheeled carriage 11 is provided with tubular sockets 14 into which may be inserted horizontal lugs 10 formed at the lower ends of metal leg members which form part of the " skeleton " around which the body of a toy animal 1 is built. The members 8 are resilient to facilitate the engagement of the lugs and sockets, and the tendency of the members to splay when the animal is sat on produces more positive engagement of the lugs and sockets. The "skeleton" comprises three strip members welded, riveted or otherwise secured at their horizontal portions 5, 7, and the spacing of the lugs and sockets is such that the animal may face to the front or to the rear of the carriage. The sockets may be of inverted channel form and may be mounted on lugs provided on the carriage. If the toy animal is used separately from the carriage, the lugs 10 constitute flat feet which do not damage the supporting surface. The animal may be in the form of an elephant and the positions of the sockets and lugs may be interchanged.
