Title: Improvements in the manufacture and production of artificial threads
IPC: D01F2/06
Filed: 1928-10-04
Abstract: 327,671. Johnson, J. Y., (I. G. Farben. industrie Akt.-Ges.). Oct. 4, 1928. Right to Patent relinquished. Cellulose xanthates, processes for making filaments from; apparatus for making filaments.- Viscose artificial threads having a tensile strength higher than the normal are obtained by employing spinning nozzles the length of the bore of which is five times or more the diameter, preferably ten times or more, and by stretching the filaments immediately on extrusion to an extent of five times or more their original length if metallic nozzles are used or ten or more times in the case of nozz'les made of glass, quartz glass and similar vitreous material. The fining of the filaments is stated to be possible because of the more or less perfect orientation of the cellulosic particle that occurs during the passage of the viscose through the elongated nozles. In examples, in all of which aged viscose is spun into an acid-sulphate bath, for example, that described in Specification 10094/06, metal or glass nozzles are employed having the following length and diameter dimensions :- 1.0 : 0.1 mm., 1.0:0.07 mm., 2.0 : 0.07 mm., and 2.0 : 0.09 mm.; and the filaments are stretched to 5, 20, 100 or even more times their original. length, the speed of extrusion being suitably decreased in order to prevent breakage of the filaments with the higher degrees of stretching.. Specifications 166,294 and 166,931 also are referred to.

Title: Process for recovering petroleum
IPC: C09K8/584
Filed: 1963-07-24
Abstract: An emulsion used in the recovery of petroleum from underground formations comprises: a non-polar material such as mineral, animal or vegetable oils, ethylene dichloride, dichloroethyl ether, and propylene dichloride; a polar material such as water, methanol, ethylene glycol, ethyl acetate, methyl formate, acetone, methyl ethylketone, formamide, and acetamide; and a surfactant. Suitable surfactants are sodium glyceryl mondaurate sulphate, dihexyl sodium succinate, hexa-decyl-naphthalene sulphonate, diethylenglycol sulphate, glycerol disulphoacetate monomyristate, p-toluidene sulphate laurate, p-chloroaniline sulphate laurate, sodium sulphato oleylethylanilide, triethanolamine myristate, N-methyltaurine oleamide, pentaerythrital monostearate, pdyglycerol monolauriate, triethanolamine oleate, morphiodine stearate, hexadecyl trimethylammonium chloride, ditetradecyl dimethyl ammonium chloride, n-dodecyldiethylenoglycal sulphate, monobutylphenyl sodium sulphate and triethanolamine laurate, or polyethylene glycol monolaurates or myristates.  Especially suitable surfactants for petroleum-water emulsions are alkylaryl monosulphonates where the alkyl radical contains 10-20 carbon atoms, and sodium salts of dialkylsuccinates having alkyl radicals containing 6-10 carbon atoms.  Emulsions utilizing chlorinated solvents as the non polar phase use the sodium sulphate derivative of 3,9-diethyltridecanol-6 or the sodium sulphate derivative of 7-ethyl-2-methylundecanol -4. 1-hydroxyethyl-2-heptadecenyl glyoxalidine is a suitable agent where the formation water is acidic or contains large amounts of calcium or heavy metal ions. The emulsion is made by dissolving the surfactant in one or both the immiscible materials and then incrementally stirring one material into the other.  An emulsion comprises cetane, water, a sorbitan partial fatty ester, and an alkyl aryl sulphonate, the surfactants being dissolved in the cetane and the water incrementally stirred into the resultant mixture.  In another emulsion crude oil replaces the cetane.

Title: Improvements in and relating to processes and apparatus for the electrolysis of "iron metal" salt solutions particularly of pickle liquors
IPC: C25C1/06
Filed: 1953-10-23
Abstract: 774,896. Electrolytic regeneration of pickle liquors and other solutions of salts of " iron metals." SIEMENS AND HALSKE GES. Oct. 23, 1953 [Oct. 24, 1952], No. 29362/53. Class 41. " Iron metals," i.e. iron, cobalt, nickel, chromium, manganese or a mixture of one or more of these metals, is electrolytically produced from aqueous solutions of salts of these metals and sulphuric or phosphoric acid, particularly spent pickle liquors, and deposited on mercury cathodes by employing a current density of at least 5 amps/sq. dm., preferably of 15 amps/sq. dm. or more and in conjunction with a concentration of the metal to be deposited of at least 0.2 mol. per litre of electrolyte, the cathode space being separated from the anode space by a diaphragm. Preferably an insoluble anode is used and the process is carried out in a multiple weir cathode cell having a progressively greater fall so that the mercury always presents a fresh surface, and the anode and separating diaphragm of acidresistant plastic or thin ceramic may be similarly stepped so as to provide uniform electrode spacing throughout. For ferromagnetic metals the amalgam formed is removed continuously by a stationary or moving magnetic field whether the mercury cathode is moved through the cell or not. The metal is removed as'a a powder which is later compacted from the amalgam by evaporation in an external chamber having a non-oxidizing atmosphere, e.g. vacuum, which is sealed from the outer air by the amalgam and the re-condensed mercury. Typically for iron from ferrous sulphate solution the electrolyte is fed into the cathode compartment from which the iron-free acid-enriched liquor is withdrawn, the anolyte comprising initially metal free dilute acid and being kept largely free of metal salt. If the diaphragm is very permeable a slow flow of anolyte into the catholyte may be effected by adding water sulphuric acid to the anolyte to oppose diffusion of metal ions into it. To prevent hydrogen bubbles insulating the cathode the electrolyte may be moved relatively to it. The pickling and regenerating processes may be combined as a continuous cycle or FeSO 4 .7H 2 O may be separated from the spent pickle liquor by day and electrolysed at night. Specification 667,528 is referred to.
