Patent GB-789101-A (GB)
Title: Improvements in or relating to the continuous production of iron or steel in a rotary vessel
IPC: C21B13/08
Filed: 1955-09-09
Abstract: A method of continuously-treating iron-containing material in liquid or fine grained form comprises charging such material into a crucible, kiln or other vessel rotating at high speed about its vertical axis and having a central aperture at the bottom whereby the surface of the material in vertical section is given the general form of a parabola, introducing a gas into the vessel and discharging the vessel through the bottom aperture.  The vessel may be heated and its inner surface may be of generally paraboloidal shape.  It may be charged with pig iron with or without slag-forming and cooling substances, and steel discharged, or the charge may be finely divided iron ore and coke, pig iron or steel being discharged.  By controlling the speed of rotation, tapping may be prevented or made selective of two liquid phases.

IPC: B23K1/14
Abstract: 260,100. Luxton, W. J., and Green, W. A. Oct. 20, 1925. Soldering.-In a can soldering machine of the type in which prismatic or cylindrical cans are moved across a framework with their seams dipping successively in flux or solder slots and in which an oscillating ladle is used to lift solder from a low level supply well to a high level well associated with the flux and solder slots, the pivoted rocking arms carrying the ladles are loosely connected to the operating element thereof so that it is operated thereby under normal working conditions, but so that the operating element may ride free when abnormal resistane is encountered, such as when the machine is started up with the solder in the low level well set hard. The cans may be rolled along a pair of relatively adjustable tracks 2 by a travelling ban'd 13 pressed down by loose rollers 16 and carried by arms 14 which are supported by a parallel linkage and vertically adjusted by traveling racks 18<x> and gearing from a hand wheel 17. The solder slot is formed by angle members 8. 9 removably fitted by angle bars 10. 11 held by studs 12 and is arranged in the vicinity of the front track 2. The ladles 21, which consist of hollowed hooked toes 24 leading to channelled bodies open at the ends 25, are carried by pivoted arms 22 bent at their upper ends to overhang the lower and upper rolls 19, 20 and having tails 26. connected together by a flat bar 27. The bar is formed with a recess in which normally rests a pin 31 on a connecting rod 28 operated by a crank 29 and gearing from the can traversing mechanism. If the resistance is abnormal the pin 31 rides out of the recess and worlds idly along the bar. The bar may be provided with a longitudinal slot having one edge recessed to accommodate the pin 31. A pair of ladles may be mounted on each arm so that one side may empty whilst the other is dipping. Specifications 15227/15, 17762/15, 195,129, and 215,233 are referred to.

Abstract: 315,142. Johnson, J. Y., (1. G. Farbenindustrie Akt.-Ges.). Sept. 14, 1928. Manures.-Crude calcium phosphate is decomposed with nitric acid, the phosphoric acid acted on by a calcium compound to precipitate dicalcium phosphate, the precipitate removed and after the solution is treated with potassium sulphate for a partial conversion the solution is concentrated, part or all the previously formed precipitate added, and the product solidified by cooling. An example is given of heating 1 ton of crude phosphate with the appropriate quantities of chemicals, nitric acid, milk of lime and potassium sulphate.

Abstract: A high impact copolymer is prepared by polymerizing a monomer mixture containing styrene and/or one or more of its derivatives together with acrylonitrile and/or one or more of its derivatives and/or one or more acrylic or methacrylic esters, the monomer mixture having dissolved therein a synthetic or natural rubber, and either the whole of the polymerization being effected in the presence of water and once the conversion degree has reacted from 10 to 50% by weight a suspension system consisting of a mixture of a partially hydrolysed polymer of an ester of acrylic and/or methacrylic acid and polyvinyl alcohol is added, or the polymerization being initially effected in bulk and once the conversion degree has reacted from 10 to 50% by weight the remainder of the polymerization is effected in aqueous suspension in the presence of the said suspension system.  The copolymer produced may be mixed with a polymer or copolymer, e.g. of styrene, alpha-methyl styrene, acrylonitrile or methyl-methacrylate. In Examples 1 to 5, polybutadiene is grafted with styrene and acrylonitrile in the presence of di-t-butyl peroxide and t-dodecyl mercaptan, the polymerization being carried out in bulk initially and the suspending agent used in the second stage being partially hydrolysed polymethyl methacrylate and polyvinyl alcohol.
