Patent GB-810428-A (GB)
Title: Process for the production of multivalent metals and non-metals
IPC: C22B34/14
Filed: 1957-02-18
Abstract: Multivalent metals and non-metals are prepared by reducing a higher halide thereof to a lower halide with a deficit of alkali metal at a temperature above the melting-point of the alkali metal and below the melting-point of the alkali metal halide thereby forming a finelydivided mixture of a lower halide of the element and the alkali metal halide the former of which is then reduced to the element with the required additional amount of alkali metal. The extraction of zirconium and hafnium are quoted as examples and in the latter case, hafnium tetrachloride was reacted at 200 DEG  C. with 25 per cent of the amount of sodium required for complete reduction and the resulting dry mixture of solid was transferred to a sintering vessel to which the remaining 75 per cent of sodium was added, the mixture heated to 960 DEG  C. and the hafnium sponge was recovered by an acid leaching process.  Other multivalent elements to which the invention is said to be applicable are Am, Sb, Bi, Cs, Ce, Cr, Co, Cu, Eu, Ga, Ge, Au, In, Ir, Fe, Pb, Mn, Mo, Np, Ni, Nb, Os, Pd, Pt, Po, Re, Rh, Ru, Sm, Tc, Tb, Tl, Sn, W, U, V, Yb, P, As, S, Se, Te and B.

Abstract: 727,803. Fibre drafting apparatus. BISINGER, B. March 3, 1952 [March 3, 1951 ; July 31, 1951 ; July 31, 1951], No. 5540/52. Class 120(2). Fibre drafting apparatus for spinning, roving and like frames comprises two pairs of drafting rollers and retarding means intermediately located consisting of a pressure roller supported by a pair of bottom rollers each of which bears substantially the same proportion of the weight of the pressure roller. The retarding means may consist of a comparatively large pressure roller 7 provided with a cover of soft, yieldable material, such as cork, leather, natural or synthetic rubber, polyvinyl chloride, polyvinyl alcohol or compounds derived from these polymers. In order to extend the area of influence of the retarding means, a small pressure roller 25 may bear upon the roller 3. A leather belt may pass around the bottom rollers 2, 3, or an apron may extend over the roller 3 and forwardly over a guide bar and then over a tension roller disposed beneath the roller 3. In the latter form, the pressure roller 25 may rest upon the apron as it passes over the guide bar. A condenser 23 may be located before the rollers 4, 9 which serve as delivery rollers, unless another pair of rollers is employed forwardly of the rollers 4, 9. Drafts of less than 2, preferably from 1À05 to 1À5 are stated to be advantageous between nip lines a, b and greater than 2, preferably from 4 to 6, between nip lines c, d.

IPC: C23C8/26
Filed: 1931-02-26
Abstract: In a process of nitrogenizing iron, steel, and alloys thereof, the nitrogenization is effected by a gaseous nitrogenizing agent to which has been added an organic compound containing nitrogen. Aliphatic aromatic and heterocyclic compounds may be used such as carbocyclic compounds containing one or more nitroradicals, e.g. nitrobenzene and mono-nitrotoluene, amino compounds, e.g. aniline phenylene-diamine and alpha-naphthylamine, and heterocyclic compounds containing nitrogen in the ring, e.g. pyridine and quinoline.  The gaseous nitrogenizing agent may be passed through the organic nitrogen compound which is heated to a temperature just below its boiling point.  In an example an alloy containing 95,5 per cent of iron, 1 of aluminium, 1,7 of chromium, 0,1 of molybdenum, 0,3 of carbon, 0,5 of manganese, 0,3 of silicon, and the remainder phosphorus sulphur &c. was placed in a closed container and ammonia which was bubbled through nitrobenzene was then passed through the container, the container being heated to 460 DEG  C. for 4 hours.

Title: Improved process for the production of extensible contractile tubular, annular or the like film products, for example caps or rings for stoppering bottles
IPC: B29D99/00
Filed: 1947-03-06
Abstract: Extensible contractile tubular, annular, or like film products such as bottle caps, rings, or the like are obtained by a wet coagulation process from a solution of a synthetic resin in a solvent mixture containing a plasticizer for the synthetic resin and a liquid which is a solvent or swelling agent for the synthetic resin, is miscible in large proportions with a non-solvent of the synthetic resin, and is sufficiently volatile to be capable of subsequent substantial removal by evaporation, and the film products during manufacture, and while still in the wet gel state, are treated with a mixture of the same solvent and plasticizer as those of the solution from which they have been formed but mixed with a proportion of non-solvent higher than any proportion thereof which may be in the film-forming solution. Preferably, the diluted solvent and plasticizer with which the film products are treated is the coagulating liquid.  Fillers, dyestuffs, and other substances may be incorporated in the film-forming solution.  In an example, a solution of polyvinyl chloride in acetonylacetone containing tricresyl phosphate as plasticizer, and not more than 0.2 per cent of water, if any, is spread uniformly on a cap former, e.g. by immersion and draining. The former is then immersed in a mixture of 85-90 per cent acetonylacetone, 12-15 per cent of water and 1-2 per cent of tricresyl phosphate.  It is then washed.  The cap obtained is removed from the former and stored in water.  Residual solvent is removed with the water by evaporation when the cap is subsequently dried. Specifications 587,309 and 644,790 are referred to.

Plane-trigonometry calculators.-A device for solving triangles in navigation comprises a triangular card marked with directional grid lines b, c and also with lines l radiating from one angle e of 45‹ and representing object bearings off the bow. To determine the distance of a fixed object, its bearings are taken at two different times and the distance run, say f, during the interval is taken off a scale such as that at d and fitted between the corresponding bearing lines and parallel to one or other of the directional lines. The distance may then be obtained by measurement along the second ;bearing line. Lines m may be added constituting isosceles triangles as a reminder that in doubling a bearing the distance run between the observations equals the distance of the object at the end of the run.
