Filed: 1974-07-11
Abstract: 1473565 Treatment of charge for reactors CENTRO SPERIMENTALE METALLURGICO SpA 11 July 1974 [6 Aug 1973] 30866/74 Heading C1A The solid particulate charge to be fed into fluidized bed reactors, is treated by separating therefrom a first fraction of fines, thus leaving a second fraction of charge material which is fed to the reactor, withdrawing from the reactor fines suspended in fluidizing gas, separating a second fraction of fines from said withdrawn fluidizing gas, admixing the first and second fractions of fines, micropelletizing the admixed fines, and feeding the micropellets as charge material to the reactor, either in green state, or after drying or kilning. Separation of the first fraction, which is suitably 20 to 70% by weight of the total fines present in the charge material, may be effected by screening or by a fluidized bed treatment. A particulate iron ore to be fed into iron ore direct reduction fluidized bed reactors may be so treated, the separation being effected in a fluidized bed fluidized with hot combustion products whereby the charge material is heated to 400‹ to 500‹ C.

IPC: B03B5/62
Filed: 1962-08-13
Abstract: 942,780. Classifying granular materials. WHITING CORPORATION. Aug. 13, 1962, No. 30921/62. Headings B1G and B1H. A hydraulic classifier comprises a vessel 20 having means 26 for circulating slurry in a generally toroidal flow pattern with the principal axis of the pattern vertical, at least one elutriating column in the vessel having a channel of uniform cross-section for at least a part of its height and having an inlet which is near to the periphery of the toroidal flow and an outlet substantially above the lower end whence slurry can be drawn by means 34 to establish a flow in the column independent of the toroidal flow at a velocity such that particles only finer than a predetermined size are suspended in the column. The classifier is adapted for a combined classification and crystallization process. The elutriating column comprises the annular space between the central cylindrical wall section of the vessel 20 and the skirt of its upper dome 23 which projects into the vessel. The circulation control means is a pump 34 from which the delivery may be controlled by flow valves. Feed from a line at 43 is introduced into the vessel below the baffle 25 at 32 and at 33. In the narrow portion 22 of the vessel it forms a teeter-bed in which the smallest-settling crystals are fluidized whilst the larger crystals are withdrawn at 31 to a filter 41 whence the filtrate is pumped to combine with the outflow of fines and solution from the column outlet 30 in a settler 35. Fines from the settler 35 are redissolved in a heat exchanger at 40 and returned to the vessel at 32. A connection 32 is provided at the top of the vessel from which vapour can be withdrawn or (Fig. 4, not shown) ammonia gas introduced. Alternatively the top of the vessel may be open (Fig. 1, not shown).
Patent GB-310869-A (GB)
Abstract: 310,869. Geller, R. May 2, 1928, [Convention date]. Antiseptics; ointments.-An alcoholic solution of iodine and potassium iodide is solidified by means of the sodium salts of benzoic, phthalic, or salicylic acids or mixtures thereof, the salts being formed in the solution by neutralization of the free acids. Salts of higher fatty acids, such as sodium palmitate or sodium stearate. may be used in substitution for part of the aromatic acid salts. According to an example, a solution of metallic sodium in alcohol is added to a hot alcoholic solution of benzoic acid. Iodine and potassium iodide are added to the mixture, and the whole poured into moulds and cooled. Excess of the acid may be used so that some free acid remains in the final product. The Specification as open to inspection under Sect. 91 (3) (a) states also that salts of the fatty acids alone may be employed to solidify the alcoholic solution, and in the example states that sodium hydrate may replace the metallic sodium. This subject-matter does not appear in the Specification as accepted.

Title: Method of removing ethers from mixtures with hydrocarbons or hydrocarbon halides
Inventor: ROSSMY GERD
IPC: C07C17/38
Filed: 1958-10-01
Abstract: A mixture of an aliphatic hydrocarbon or aliphatic hydrocarbon halide and a dialkyl ether containing up to 6 carbon atoms is treated to remove ether therefrom by reacting the mixture at room temperature with a solid or liquid metal halide capable of binding the ether additively and separating the purified hydrocarbon or hydrocarbon halide from the reacted mixture.  The mixtures to be treated may be brought into contact with the metal halide in the liquid or gaseous state.  The separation of the purified material may be effected by distillation or filtration.  The metal halide-ether addition compounds obtained as residue may be treated with water to recover the ether or be thermally decomposed to yield alkyl ethers.  Examples describe the removal of ether from mixtures of methyl chloride and dimethyl ether using ZrCl4, SnCl4, AlCl3, ZnCl2 and TiCl4; the removal of dimethyl ether from its admixture with isobutane using AlCl3 and the removal of diethyl ether from its admixture with ethyl chloride using TiCl4.  Ferric chloride is also specified.
