Title: Improvements in textile twisting machines
Inventor: BATES ERIC
IPC: D01H13/10
Filed: 1957-09-02
Abstract: 852,260. Controlling delivery of yarn from bobbins. PRINCE-SMITH & STELLS Ltd. Aug. 1, 1958 [Sept. 2, 1957], No. 27557/57. Class 120(2).  Each supply yarn of a twisting machine passes under a rider such as 30 slidable on spaced guides 26, 27 and arranged to rise and fall in response to variations in yarn tension in order to prevent breakage or the formation of snarls in the yarn. The guides 26, 27 are splayed outwardly at their lower ends to retain the rider 30; each pair of guides is supported on an offset 25 mounted on an arm 19 which is articulated as at 20 for access to the creel and normally held in position by springs such as 24. Each yarn passes from a loop 30 over a double disc tensioner 28 fixed in alignment with the package axis and thence over guides 32 to the twisting unit. A fixed guide 31 is provided to facilitate threading a yarn through the tensioner 28. In the provisional specification each yarn passes through the eye of a guide arm pivoted about an axis parallel to the packet axis. The guide arm has an associated mercury switch which, when the arm drops due to a decrease in yarn tension, closes a circuit to stop the spindle motor and disengage the drive of the delivery roller. Specification 836,470 is referred to.

Abstract: 1,141,498. Stillages; roller conveyers. W. J. PARKER and W. M. PARKER. 19 Sept., 1967 [21 June, 1966], No. 27581/66. Headings B8A and B8H. A stillage for use in combination with a fork-lift truck 24 in transporting billets 20 and such like comprises a rectangular frame 10 supported by four legs 11 which project above the frame 10 to form spigots 12. A rectangular metal deck 16 is mounted on the frame 10 so that either its front or leading side or its rear side or both can be raised relative to the frame 10. The deck 16 is stiffened by lengths of angle iron 14, is reinforced with two parallel angle iron bars 17 and has stiffeners 18 of box section. At a loading station, Fig. 1, a loading platform 19 is slightly inclined so that it slopes downwardly to the delivery end thereof. A base 21 is provided to receive the stillage and has a ramp 22 on which the forward stiffener 17 is deposited when the fork-lift lowers the stillage on to the base 21. The forward end 16a of the deck 16 is thus raised relative to the frame 10 so that it registers with the delivery end of the platform 19 and billets 20 can roll along the deck. The loading station has front and rear stops 25, 25a, respectively, operated by bell cranks 26, 26a and a push-rod 27 by which a specified number of billets 20 are allowed to run on to the platform 19. A receiving station (30), Fig. 2 (not shown), has a platform (31) downwardly inclined at its rear end. When the loaded stillage is deposited on a base (32) a ramp (33) raises and tilts the deck 16 so that the billets 20 may roll off. The stillages may be stacked and when loaded form a stock pile, Fig. 5 (not shown). The loading platform, the deck of the stillage and the discharge platform may each have a series of parallel conveyer rollers 36, Fig. 6, so that boxes and cases can be transferred from the loading platform to the deck and from the deck to the discharge platform.
Patent GB-734030-A (GB)
Title: Process for the production of aldehydes free from metals and acetals
IPC: C07C27/22
Filed: 1952-11-03
Abstract: An aldehyde-containing product, obtained by the addition, in the presence of a catalyst containing cobalt or iron, of hydrogen and carbon monoxide to an olefinic organic compound, is treated with liquid water at elevated temperature and pressure, whereby compounds of the catalyst metal present in solution are converted into a form, insoluble in the aldehyde-containing product. Aldehydes are thus obtained substantially free from metals and acetals.  The process may be carried out at a temperature in the range 100-250 DEG  C.  It is advantageous when distilling the crude aldehyde mixture treated in accordance with the process to add alkaline-reacting materials such as magnesia and alkali metal or alkaline earth metal salts of carboxylic acids.  In the examples: (a) a mono-olefinic terpene of empirical formula C10H16 is treated with water-gas in the presence of a cobalt-magnesia-kieselguhr catalyst and the resulting aldehyde-containing mixture is treated at elevated temperature and pressure; (b) a C9 fraction obtained by the hydrogenation of carbon monoxide and containing about 50 per cent of olefinic hydrocarbon is treated with water-gas in the presence of chrome-nickel steel and the resulting mixture is treated with water at elevated temperature and pressure; metal-free C10 aldehyde with the C10 alcohol is obtained by distilling the resulting mixture; (c) a C6 fraction containing olefin hydrocarbon is treated with water-gas in the presence of cobalt-sulphate-magnesium sulphate solution; the product is treated with water at elevated temperature and pressure to give pure aldehyde with some alcohol; (d) a crude C7 aldehyde mixture obtained by the Oxo process is treated with water at elevated temperature and pressure to give aldehyde free from acetals; (e) camphene aldehyde obtained by the treatment of camphene with hydrogen and carbon monoxide is treated with water at increased pressure to give a mixture from which the pure aldehyde is obtained by distillation; the residue is hydrogenated to give an alcohol of formula C11H20O. Specification 719,375 is referred to.

Patent GB-642333-A (GB)
Title: Improvements in the manufacture of textile yarns and fabrics
Filed: 1947-10-15
Abstract: Crepe yarns are produced by sizing a yarn of an organic derivative of cellulose with a size containing a water-soluble cellulose ester of an organic acid and afterwards imparting a crepe twist while the yarn is under the influence of steam, or other hot aqueous medium.  When a water-soluble cellulose acetate is employed for the size composition, the composition may be prepared by acetylating cellulose with organic acids by employing acetic anhydride and an acid esterification catalyst, such as sulphuric acid, together with glacial acetic acid. The sulphuric acid may amount to 9 to 20 per cent on the weight of cellulose. When acetylation is completed water is added and the solution is allowed to ripen until the cellulose acetate has an acetyl value of from about 19 to about 29 per cent.  The cellulose acetate may then be purified and dried.  Alternatively, the water-soluble cellulose acetate may be prepared from acetone-soluble cellulose acetate.  The size composition may contain a softening agent, for example urea, diethylene glycol, polyethylene glycol, or polypropylene glycol.  Specifications 437,019, 438,589, 438,590, 438,591 and 438,654, [all in Group IX], are referred to.

Abstract: 1,268,903. Measuring dimensions photoelectrically. T. I. (GROUP SERVICES) Ltd. May 27, 1969 [June 12, 1968], No.27885/68. Heading G1A. An optical gauge for determining a dimension of an object 9 comprises two photo-detectors 10, 11 whose axes are spaced a nominal distance apart and a scanning member 12 having a plurality of equi-angularly spaced apertures 14 separated by a distance equal to the said nominal distance and on to which is focused an image of the object 9, rotation of the disc causing the photo-detectors to be alternately obscured and illuminated so that the detector outputs are indicative of departures from the nominal distance of the relevant image dimension. As shown, a lamp 15, condenser lens 16 and focusing lens 17 provide the image, but the lamp and lens 16 may be replaced by a diffuse illuminating screen. If a heated object is used, only the lens 17 is necessary for image formation. Fig. 3, shows an image of exactly the nominal size formed on the rotating disc, causing the photo-detector outputs to be delayed with respect to one another with the leading edge of one coinciding with the trailing edge of the other. If the image size is smaller than the nominal distance, the two outputs will overlap, Fig. 4 (not shown), whereas a larger image size than the nominal distance results in separation of the signals, Fig. 5 (not shown). The extent of overlap or separation depends on the departure from standard of the image size and is indicated on a centre zero measuring instrument (18) which forms part of a measuring circuit, Fig. 6 (not shown), in which two NAND gates (23, 24) are provided, one to produce pulses of a duration proportional to output overlap, the other producing pulses depending on output separation.

Patent GB-279916-A (GB)
Abstract: 279,916. Dreyfus, H. June 1. 1926. Aliphatic acid anhydrides, particularly acetic anhydride, are prepared by heating the corresponding acid in the vapour form, and condensing or extracting the anhydyride from the reaction products without condensing or extracting the water. The starting material may comprise dilute or concentrated acid, and the pyrogenic decomposition, which is carried out at a temperature of 200-1200‹ C., may be effected in tubes of copper, iron, earthenware, &c., in the pre sence of a catalyst and under raised or reduced pressure. For condensation of the anhydride vapour, the reaction gases are led through one or more fractionating columns maintained at a temperature between the boiling-points of the anhydride and of water under the pressure conditions obtaining. Separation by extraction is effected by passing the reaction gases through solvents or solvent mixtures which are substantially insoluble in water and non-volatile in steam and are of boiling-point higher than that of water -the solvent being maintained at a temperature between the boiling-points of water and of the anhydride-solvent mixture-and then recovering the dissolved anhydride, say by fractional distillation. Preferably the solvents are circulated from the absorption zone, through distillation apparatus heated to a high temperature, back to the absorption zone again. Instead of using solvents in the liquid state, their vapours may ba mixed with the reaction gases and the resulting mixture subjected to condensation. Solvents mentioned are chlorbenzene, p-dichlorbenzene, benzylether, tetrachlorethane, paraffin oil, acetylglycerins, e.g. triacetin, phenetol, anisol, cresols, and p-cresol acetate. Air, nitrogen, or other inert gases may be present. The process is described with reference to the production of acetic anhydride from dilute or concentrated acetic acid, and the preparation of propionic anhydride from propionic acid is also referred to. Reference has been directed by the Comptroller to Specifications 256,663, 256,664, and 257,968.
