Title: Process for the selective extraction of oxygen-containing organic compounds from their mixtures with aliphatic hydrocarbons
IPC: C10G21/12
Filed: 1949-06-13
Abstract: Oxygen-containing compounds are extracted from mixtures with aliphatic hydrocarbons, such as products of catalytic hydrogenation of carbon monoxide, addition of water gas to unsaturated hydrocarbons, and oxidation of paraffins, by treating with polyhydric alcohols, aromatic nitro or amine compounds or oxygen compounds of the furan group, viz. furan, furfural, their alkyl derivatives or partially or completely hydrogenated derivatives, which are liquid under the extraction conditions. Glycol, glycerine, aniline, nitrobenzene, furfurol, their alkyl derivatives, mono- or di-methyl glycol, trimethylene glycol or mixtures thereof are suitable.  Up to 10 per cent by volume of water may be added to improve the selectivity.  Small amounts of monohydric alcohols such as methyl or ethyl alcohol may be added to polyhydric alcohols to increase their solvent power.  A fraction boiling at 50-70 DEG  C. obtained from carbon monoxide hydrogenation may be admixed with the other extractants. Extraction towers in series or cascade, with packing or distributers may be used.  A subsequent water wash of the hydrocarbon may be effected to remove residual alcohols.  In examples, carbon monoxide hydrogenation products and olefin carboxylation products are extracted in a series of towers with glycol or glycol followed by glycol, methanol mixtures.

Title: Metallurgical processes for producing materials or articles of platinum or allied metals, or their alloys, and materials or articles made by or from the products of such processes
Inventor: SMITHELLS COLIN JAMES
IPC: C22C1/04
Filed: 1943-09-24
Abstract: A metallurgical process consists in agglomerating by pressing and sintering metals of the platinum class with or without alloying ingredients in amounts yielding cold-working alloys with alumina, the quantity of which is not greater than 10 per cent by weight of the metal, all the ingredients being in a finely divided condition, the sintered body being subsequently swaged, rolled, drawn or otherwise treated to bring it into the form of a wire or sheet suitable for use in the production of desired articles. The alumina may be partly replaced by one or more other oxides which are stable at the sintering temperature whether or not the sintering process is carried out in the presence of hydrogen or other reducing gas, the major part of the total oxide content being alumina.  The agglomerate may consist mainly of platinum alloyed with rhodium, palladium, iridium, ruthenium or tungsten, e.g. 5-30 per cent of rhodium, the proportion of oxide being 0.01-1.0 per cent of the weight of the metal, or tungsten in the range of 1-8 per cent of the platinum and about 0.2 per cent of oxide.  One of the following binary alloys may be used in the agglomerate, namely platinum alloyed with rhodium up to 30 per cent of the alloy, iridium up to 30 per cent of the alloy, ruthenium up to 15 per cent of the alloy, tungsten up to 8 per cent of the alloy, gold up to 15 per cent, molybdenum up to 8 per cent, manganese up to 8 per cent, cobalt up to 15 per cent or nickel up to 15 per cent.  The process may be carried out in the following manner. Ammonium chloroplatinate containing 90 grammes of platinum is suspended in 100 c.c.s. of distilled water.  To this is added 10 grammes of rhodium in the form of ammonia hexachlororhodate and 0.25 grammes of alumina in the form of aluminium hydroxide.  The resultant paste is dried with constant stirring and heated to about 350 DEG C to decompose the mixture to metal and alumina, and finally to about 600 DEG C.  The product is crushed and heated in hydrogen at about 850 DEG C to reduce any rhodium oxide.  The resultant powder is sieved, pressed at about 30 tons per square inch and sintered at about 1400 DEG C-1500 DEG C in hydrogen for about 1 hour.  The agglomerate may be used in the production of sparking plug electrodes, thermo-couples, electric-furnace heating elements and wire gauzes or the like for use as catalysts in chemical operations.

Patent GB-786883-A (GB)
Title: Method of purifying uranium
IPC: C22B60/02
Filed: 1945-06-20
Abstract: In the production of uranium having an extremely low boron content, uranium metal preferably obtained electrolytically is converted to an oxide and the oxide heated to a temperature above 1000 DEG  C. for sufficient time for the boron impurity to volatilize. The oxide is thereafter converted to the metal having a boron impurity as low as 0.5 ppm.  The initial uranium may be obtained for example by the electrolysis of potassium uranous fluoride which may be prepared by a photochemical reduction, preferably using sunlight of a solution containing a uranium salt such as the nitrate, potassium fluoride, hydrofluoric acid and a reducing agent such as formic acid or sucrose.  Such potassium uranous fluoride precipitate is removed, washed, dried and introduced into a bath of fused sodium and calcium chlorides in a graphite crucible with a molybdenum cathode.  On electrolysis at a temperature of about 900 DEG  C. boron contaminated uranium metal collects on the cathode which is removed, crushed and ground and thereafter burnt to form an oxide of uranium.  The oxide is then heated to a temperature of about 1200 DEG  C. whereby the boron is volatilized and the thus purified uranium oxide may be converted to the nitrate and uranium metal again produced electrolytically as before.

Abstract: 1432017 Magnetically active devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 April 1973 [7 April 1972] 16035/73 Heading H3U A wafer, Fig. 1, of crystalline magnetizable material can be so prepared that its structure takes the form of a lattice, sides D, pD of magnetic domains 2-8 within each of which the saturation magnetization, M s  is in a sense opposing an external field H 0 , the remainder of the structure having saturation magnetization in the same sense as that of the field. A material so prepared can support waves comprising quasielastically bound movements of the boundaries of the magnetic domains. When such a wafer 10, Fig. 5, is placed in the field of permanent magnet 26, there further being windings, connected to terminals 19, 20 and encompassing magnetically soft polepieces 17, 18 providing a variable magnetic field component, the distinct velocities of longitudinal, or transverse, waves can be varied over disclosed ranges as the external field is varied, the corresponding variation in the spacing of the domains in the lattice, and the elastic properties of the wafer being discussed with reference to Figs. 2-4 (not shown). The lattice structure is created by exposing it to a loop carrying a high value pulsed alternating current, and gradually moving the loop away, or by saturating it with the bias field H 0 , which is then gradually reduced, while having an amplitude modulation of size 10% of the saturation magnetic field imposed at 100 kHz. Delay line, Fig. 5.-Flat vapour deposited winding 11, receives an external signal causing the generation of waves passing to output winding 14. Variation of the bias field enables continuous variation of delay time. Filter, Fig. 6 (not shown).-The wafer (21) supports a sinuous conductor 22, providing magnetic field coupling to the wafer sequentially in opposed polarity senses defining a given resonating wavelength (25), the corresponding frequency being continuously variable in dependence on the field H o . Wafer materials are disclosed, as are the ranges of workable frequencies for such materials. It is stated that lower frequencies for given size, and greater ranges of variation are possible, than for known magnetically controlled devices. A theoretical discussion is given.
