Title: Improvements relating to the manufacture of yarns
IPC: D02J3/02
Filed: 1939-06-09
Abstract: 529,821. Yarns. BELL, A. S. June 9, 1939, No. 16858. [Class 120 (iii)] A yarn containing staple fibre is formed from a bundle of continuous filaments by subjecting the bundle to a ring- spinning operation, controlling the balloon formed by the bundle by a guide ring surrounding the ring spindle, and causing the balloon to contact with a cutting device between the guide ring and the point where the bundle reaches the winding package so that the bundle is subjected to a cutting action that severs the filaments therein without breaking the continuity of the bundle as a whole. As shown two yarns 1, 2 are doubled together, the yarn 1 passing between a pair of feed rollers 5 to a guide rod 9 and down through a slotted member 10 where the yarn 1 joins the yarn 2 fed by a pair of rollers 7 driven at a lower peripheral speed than the rollers 5. The member 10 is mounted on an adjustable arm ' 11 pivoted on the rod 9 and from the slot in the member the yarns pass to the guide ring 21 surrounding the spindle 13 and past the cutting member 24 to the traveller 17 on the ring 16. Since the yarn 1 is fed faster than the yarn 2 it forms a spiral around the yarn 2 and the cutting action of the member 24, which may be a fine file, is mainly confined to the yarn 1. The guide ring 21 and the file 24 are adjustably carried by a vertical rod 20 secured to the ring rail 18. The spindle 13 may be driven through an infinitely variable gear box so that its speed may be continuously reduced during the twisting operation to maintain a constant form to the balloon. Specification 399,838 is referred to.

Patent GB-781735-A (GB)
Title: Synthesis of nucleoside polyphosphates
IPC: C07H1/02
Filed: 1955-06-15
Abstract: A nucleoside polyphosphate is obtained by reacting a mononucleotide with phosphoric acid in the presence of a carbodi - imide and an aqueous pyridine solvent medium, said mononucleotide having more than one unsubstituted hydroxyl group in the phosphate grouping thereof. Specified carbodi-imides are those having the formula R1N = C = NR11 wherein R1 and R11 may be the same or different aliphatic (including cycloaliphatic) or aromatic groups, e.g. carbodi-imides in which R1 = R11 = cyclohexyl; R1 = R11 = p-tolyl; R1 = cyclohexyl, R11 = isopropyl; R1 = cyclohexyl, R11 = phenyl; and R1 = p-tolyl and R11 = phenyl.  It is desirable to use a substantial excess of the phosphoric acid, e.g. 5 to 15 mols. of the phosphoric acid per mol. of the nucleotide starting material.  When the nucleotide starting material is insoluble in pyridine the aqueous pyridine solvent should preferably contain between 5 and 30 per cent by volume of water based on the volume of the pyridine and when the nucleotide is soluble in pyridine the proportion of water should preferably be from 2 per cent to 30 per cent based on the volume of pyridine.  Examples are given for the conversion of adenosine-51-monophosphate to adenosine-diphosphate and adenosine triphosphate and to mixtures of the di- and tri-phosphates, using dicyclohexyl carbodi-imide and di-p-tolyl carbodi-imide respectively as the carbodi-imide, the products being separated from the mixture by filtering to remove the disubstituted urea formed and adding Lohmann's reagent to the filtrate to precipitate the mercury salts of the adenosine mono- and poly-phosphates from which the free acids are liberated, by treating the salts in aqueous suspension with hydrogen sulphide.  The polyphosphates are separated by neutralizing with sodium hydroxide followed by ion exchange chromatography and may be finally recovered in the form of their barium salts. Alternatively, the mixture of adenosine mono-, di- and tri-phosphates may be separated by adding sodium hydroxide to bring the pH of the hydrogen sulphide-freed solution of free acids obtained from the mercury salts to pH 3.8, adding barium acetate to precipitate the barium salt of the triphosphate which is removed by centrifugation, the diphosphate being precipitated from the supernatant liquid by raising its pH to 8.5.  Other nucleoside polyphosphates which are stated to be obtainable by the process are the 51-di- and tri-phosphates of guanosine, cytidine, inosine, desoxyadenosine, desoxycytidine, desoxyguanosine, and thymidine.
