Title: Improvements in or relating to the manufacture of stretch/bulk yarn by false twisting yarn of synthetic organic material
IPC: D02G1/02
Filed: 1955-01-31
Abstract: 788,944. Twisting and finishing yarns and filaments. KLINGER MANUFACTURING CO.. Ltd., GILCHRIST R. S.. and MATTINGLY, D. A. E. Jan. 26, 1956 [Jan. 31, 1955; Nov. 22, 19551, Nos. 2885/55 and 33499/55. Classes 120(2) and 120(3) Multifilamentary yarn or monofilaments of synthetic organic material e.g. polyamides, polyesters, polyvinyl chloride, are given stretch/bulk properties by subjecting the yarn having little or no twist (or an untwisted assembly of the filaments) to two or more successive and superimposed false twisting processes i.e. passing through a spinning head disposed between two guides which restrain the yarn from twisting thereat so that the yarn in passing from one guide to the spinning head is twisted while plastic and then set and in passing from the head to. the other guide is untwisted to the same extent, the successive false-twists being applied in opposite directions. As shown in Fig. 1, a nylon yarn is led from a package 10, through a tensioning device 11, around a feed roller 12, over an oil-heated tongue 13 whereon it is subjected to a gradually increasing temperature, through a spinning head 18, around a take-off roller 19, thence to a spool 20 on which it is wound by a drum 22: the spool 20 then replaces the package 10, the rotation of the head 18 is reversed, and the process is repeated but with diminished severity of false-twist and temperature applied by the tongue 13. The apparatus is driven from a motor 40 which rotates a shaft 39 driving the head 18 (through belt 35 and pulleys 34, 36) and a variable speed and reversing box 25 which drives a shaft 23 of the drum 22 and the rollers 12 and 19 (through chains and sprocket wheels). As shown in Fig. 2, the false-twisted yarn passes directly from roller 19 to a duplicate apparatus operating at reduced speeds and comprising a heating tongue 113, spinning head 118 and take-off roller 119, and is spooled at 20. The motor 40 drives the head 118 through a variable speed and reversing gear box 41 and the box 25 through gearing 8, and the drives for all the rollers 119, 19, 12 are derived from the shaft 23 via chains and sprocket wheels. In crimping monofilaments, Fig. 3 (not shown), a number of filaments are assembled in untwisted form, then passed through the apparatus of Fig. 1 or Fig. 2 as a single yarn, and thereafter separated: individual filaments, Fig. 5 (not shown) have a "double wavy" formation comprising shorter waves superimposed on longer waves. Specification 788,526 is referred to.

Title: Improvements in gas producers
IPC: C10J3/66
Filed: 1928-01-30
Abstract: 301,241. Ekelund, S. C. G. Jan. 30, 1928. Producers. - In a slagging gas producer, the fuel is preheated by contact with the producer gas, and the volatiles, together with the producer gas are wholly or partly introduced into the hot zone of the producer. The air for gasification is preheated so that the gas evolved has a high temperature suitable for the reduction of ores or the melting of metals. Air is supplied through an annular conduit 1 and tuyeres 2 and the gas rising through the fuel bed 6 passes partly through flues 7 and partly through a pre-distilling chamber 10, the gases from which pass by pipe 11, duct collector 12, and condenser (not shown) to a blower 13 which forces them through an annular conduit 3 and tuyeres 4 and partly through pipes 5 connected' to the air tuyeres. The gas is burned with air as it enters the producer, and slag is removed through a hole 15 pig iron being run off below the slag when ores are treated. In a modification the fuel preheating chamber is separate from the main producer shaft, and may have a plunger to push the fuel into the producer, or the preheater may take the form of a rotating inclined furnace. Coke oven gas, natural gas, blast :furnace gas, flue gas of electrical blast furnaces or raw oil may be introduced into the hot zone of the producer with the air. The dust from the collector may be briquetted and charged into the producer or blown into the air or gas stream. Coal dust firing apparatus may be employed, the combustion products from which are passed into the producer. Chalk, limestone or slag may be charged into the producer and if the slag contains iron or iron ores, pig iron is obtained as a byproduct. The slag may be of use in cement making if it contains silicic acid aluminium oxide or chalk and may be improved for this purpose by the addition of titanic acid. Sulphur may be removed from the finished gas by passing it, while hot, through a layer of chalk.

Title: Process for purifying nickel
IPC: C22B23/06
Filed: 1934-01-29
Abstract: Crude nickel and scraps of impure nickel are refined by producing such an intense and violent intermixing between the metal in the molten state and a molten and very fluid slag of a suitable composition that an emulsion-like and turbulent mixture of nickel and slag is proproduced.  If sulphur is to be eliminated from the metal a basic slag free from nickel oxide with a basis of alkali and/or alkaline earth oxides and containing, if desired, a small quantity of titanium oxide or silica is used.  To eliminate impurities like arsenic, antimony and silicon whose oxides have with respect to the molecule of oxygen a higher heat of formation than nickel oxide and act as acids in the slag and to eliminate partially other impurities whose oxides have similar properties and are basic, basic or neutral slags containing nickel oxide are used.  To eliminate impurities whose oxides have similar properties and act in the slag as bases and to eliminate partially impurities whose oxides are acid, acid slags containing nickel oxide partially in the free state and partially combined with the acid constituents are used.  Said slags contain, in addition to nickel oxide, acid oxides such as silica or titanium oxide or neutral oxides such as alumina, and oxides, which are practically not reducible by the nickel such as magnesia or lime.  To extract nickel oxide and other oxides dissolved in the nickel, slags, preferably acid, containing no nickel oxide or very little and which possess a high power of absorption with respect to nickel oxide are used.  Before or during the refining treatment metals, such as manganese, magnesium and iron which are oxidized by the nickel oxide in the metal producing oxide which are soluble in the bath and more readily absorbable by the slag than nickel oxide are used.  The process may be carried out in a series of operations in a convenient order according to the impurities present in the metal, and the purification from the same impurity may be repeated several times if necessary.  The turbulent mixing may be carried by pouring the nickel in a large jet and from a sufficient height e.g. 3 to 5 metres upon the bath of slag or may be produced by mechanical means or by violent agitation by means of gases which are incapable of interfering with the purification operations. Specifications 404,300 and 405,633 are referred to.
