Title: Improvements in and relating to the manufacture and production of artificial threadsfrom viscose
IPC: D01F2/06
Filed: 1948-02-09
Abstract: Artificial threads are produced by extruding viscose into an aqueous coagulating bath containing sulphuric acid, one or more metallic salts, a cation-active organic compound, and a lubricating agent consisting of a free fatty alcohol or free fatty acid having at least 10 carbon atoms in the molecule or a condensation product of such a fatty alcohol or fatty acid with ethylene oxide.  The lubricant and the cation-active compound may be added to the bath separately or in the form of a mixture, the term "cation-active compound" being used to include both compounds which are cation-active before addition to the coagulating bath and those which are converted into such compounds after addition to the acid bath.  A suitable mixture may be obtained by the partial condensation of a fatty acid or fatty acid ester, e.g. sperm oil, having at least 10 carbon atoms in the molecule, with an aliphatic polyamine, e.g. triethylene tetramine, or by alkylation of the partial condensation product with, for example, dimethyl or diethyl sulphate to form a cation-active compound containing free fatty alcohol and free fatty esters.  Other examples of cation-active compounds which may be used are cetyl pyridinium bromide or lauryl pyridimium sulphate.  Examples of lubricating agents which may be used are lauryl alcohol, cetyl alcohol, octadecyl alcohol, stearic acid, palmitic acid, or a condensation product of cetyl alcohol or stearic acid with ethylene oxide.  The invention may be used in continuous spinning processes in which the thread after leaving the coagulating bath and without any break is subjected to a series of treatments and to drying and winding on to a package. In an example, viscose is extruded into a coagulating bath containing 10 per cent of sulphuric acid, 18 per cent of sodium sulphate, 1.0 per cent of zinc sulphate and from 1.0 to 2.0 grams for each kilogram of yarn spun of a mixture containing 70 parts of cetyl pyridinium bromide and 30 parts of a condensation product of one mol. of cetyl alcohol with 6 to 10 mols. of ethylene oxide. The presence of the lubricating agent and the cation-active compound in the coagulating bath is said to prevent the formation of hard deposits on thread guides, godets or thread-advancing reels.  Specifications 467,500, 469,817 and 541,099 are referred to.

Title: Method and apparatus for controlling an infinitely variable transmission
IPC: B60W10/101
Filed: 1977-01-31
Abstract: 1525674 Expanding-pulley gear VAN DOORNES TRANSMISSIE BV 31 Jan 1977 [9 Feb 1976] 03784/77 Heading F2D In expanding-pulley gearing having driving and driven pulleys 1, 2 adjustable by hydraulic pressure in piston-and-cylinder units, the tension in the transmission belt 9 is controlled by regulating the pressure supplied to the cylinder of pulley 2 with a control valve 18 and a further control valve 42 regulates the supply to and discharge from the cylinder of the other pulley 1 to adjust the transmission ratio. The pressure adjusted by the valve 18, in a supply line 16, is controlled by the speed of pulley 1 as measured by a Pitot tube 33 in a rotating fluid-filled space 32, the pressure, proportional to speed, being applied to one end of the spool 22 of valve 18. A spring 37, whose bias is adjusted in dependance on transmission ratio by a link 40 to the movable flange of pulley 2, opposes the speed responsive pressure so that the belt tension is dependent both on input speed and transmission ratio. The valve 42 has a spool 43, also acted upon by the speed responsive pressure from the Pitot 33 in opposition to a spring 45. The valve spool is in a neutral position, pressure neither being supplied to nor discharge from the cylinder space 11 of pulley 1, when the speed responsive pressure balances the spring force, an increase or decrease in input speed reducing or increasing transmission ratio respectively. The bias of spring 45 is adjusted by the inlet manifold depression of a driving I.C. engine acting on one side of a diaphragm 50 to move a piston 49. A valve 58 is electrically operated during braking to reduce the effect of the increased vacuum in the manifold when the vehicle is braked. The bias of spring 45 may also be controlled by the accelerator pedal through a mechanical link. A brake having a cylinder 74 and a shoe 79 may be operated when a clutch, between the drive motor and the driving pulley 1, is disengaged. The overflow from valve 18 is used for lubrication. The area on which the fluid pressure acts is greater for pulley 1 than for pulley 2.

Abstract: 674,438. Making compound piston-rings. MONZER, A. Feb. 14, 1950 [March 2, 1949], No. 3802/50. Class 83 (ii). [Also in Group XXVI] In a method of making compound pistonrings, a lead-bronze layer is welded by immersion casting on to a steel sleeve and the compound sleeve thus obtained is subjected, before the finishing treatment, to a pressure treatment on its inner face in order to effect a compression of the inner fibres of the sleeve, the individual piston-rings being thereafter severed from the sleeve and split. The sleeve is preferably a drop-forging, but may be made of sheet-metal bent to annular form in the direction of rolling and welded, the dimensions being such that the welded seam is cut out when the rings are split. If the pressure treatment is applied by knurling, the surface is preferably smoothed by rollers. To improve the spring action, sleeves of sheetmetal or seamless tubing may be turned down from the outside so that the sleeve contains only compressed fibres.

Title: Manufacture of di-hydroxyalkyl esters of terephthalic acid
Inventor: MUNRO NEIL
IPC: C08G63/86
Filed: 1956-02-10
Abstract: Polyalkylene terephthalates are obtained by polycondensing in known manner di-hydroxyalkyl terephthalates which are prepared by reacting a dialkyl terephthalate with a glycol of the series HO(CH2)nOH, where n is 2-10, under atmospheric pressure and at a temperature above the boiling-point of the glycol, by adding the glycol to the reaction mixture at such a rate that substantially no free glycol is present in the reaction vessel (see Group IV (b)).  In the preparation of the di-hydroxyalkyl terephthalates the glycol may be formed in situ during the reaction by reacting the dialkyl terephthalate with a di-(o -hydroxy-n-alkyl) terephthalate, so that glycol formed by polymerisation of the latter is immediately used up in the ester-interchange reaction.  The polycondensation is carried out directly on the product of the process, with the addition of a catalyst if an antimony or germanium-containing ester-interchange catalyst has not been used.  In examples, polyethylene terephthalate is prepared by heating in vacuo di-(b -hydroxyethyl) terephthalate or a mixture thereof with the corresponding polyester, obtained as described above. Specification 795,968 is referred to.ALSO:Di-hydroxyalkyl terephthalates are prepared by reacting a dialkyl terephthalate with a glycol of the series HO(CH2)nOH, where n is 2-10, under atmospheric pressure and at a temperature above the boiling-point of the glycol, by adding the glycol to the reaction mixture at such a rate that substantially no free glycol is present in the reaction vessel.  The glycol is preferably added gradually so that the reaction temperature is maintained at the desired figure. The glycol may also be formed in situ during the reaction by reacting the dialkyl terephthalate with a di-(o )-hydroxy-n-alkyl)-terephthalate, so that glycol formed by the polymerization of the latter is immediately used up in the ester-interchange reaction.  Ester-interchange catalysts which may be used are antimony or germanium and compounds thereof, such as oxides, salts of organic or inorganic acids, soluble salts, e.g. potassium antimonyl tartrate, and salts of antimony or germanium acids, e.g. potassium pyroantimonate.  The dihydroxyalkyl terephthalates are polymerized in known manner to give polyalkylene terephthalates (see Group IV (a)).  In examples, dihydroxyethyl terephthalate was prepared as follows: (1) dimethyl terephthalate was heated at 250 DEG C. in a vessel fitted with a fractionating column, in the absence of a catalyst or in the presence of antimony oxide or germanium oxide and ethylene glycol was added gradually at a point two-thirds of the way up the column at such a rate as to maintain the reaction temperature at 250 DEG  C., methanol being distilled off until the theoretical amount was collected; (2) dimethyl terephthalate, di-(beta-hydroxyethyl)-terephthalate and antimony oxide were heated together, methanol being distilled off as in (1).

Abstract: 825,678. Gas-blast switches. COQ N.V. Feb. 7, 1957 [Feb. 15, 1956], No. 4306/57. Class 38 (5). In a gas-blast switch having a nozzle contact 6, a movable contact 9 co-operating with the nozzle contact, a piston 13 movable within a cylinder 11 and connected with lost motion to the moving contact, and in which the piston and cylinder have co-operating portions 13a, 19 of reduced diameter, the smaller diameter of the annular contact area 20 between the contacts is greater than the diameter of the piston portion 13a of reduced diameter but smaller than that of the unreduced portion of the piston. Thus, when the gas-blast is applied to the space 8 within the nozzle contact, the blast pressure acting on the movable contact holds it firmly in engagement with the nozzle contact until the piston 13 has moved sufficiently for the blast pressure to be applied over the whole of the piston, the contacts then being opened. In the arrangement shown, the piston 13 is movable on the stem 10 of the contact 9 between ribs 14 and the head 15 of the stem, a single spring 18 biasing the piston downwardly and providing contact pressure until the gas blast is applied. The head 15 may be formed as a bushing contact which co-operates with a movable isolating contact 16. Specification 606,860 is referred to.

Abstract: 514,620. Gas turbines; air-compressors. JENDRASSIK, ,G. Feb. 11, 1938, No. 4400. Convention date, Feb. 13, 1937. [Classes 110 (i) and 110 (iii)] In a continuous combustion, constant pressure gas turbine, the walls of the combustion chamber are spaced from the turbine casing walls, additional heat is given to the gases during expansion either by prolonging the combustion into the turbine bladings or by burning additional fuel between the stages and the last stage without such re-heating covers a pressure drop of not less than one twentieth of the total. The additional heat may produce isothermal expansion. The combustion chamber 15 is annular and co-axial with the turbine. It may be arranged externally to the gas flow, as shown, or internally. The wall 13 has a scoop 16 by which a part of the air delivered by the compressor on the left is caused to swirl into the combustion chamber. The rest passes the chamber by and mixes with the products of combustion before they enter the turbine on the right. The innermost layer of air in the compressor is extracted through ports 28, 28<1> and returned to an earlier stage of the compressor. The rotor may be cooled by air passing through ports 31. This air may be taken from the delivery of the compressor and, after passing through the rotor cavities, be mixed with the hot gases entering the turbine blading. Fuel is supplied by a pump 22 and, to avoid a periodic delivery, balancing chambers 23 may be provided. Fig. 7 shows a fuel atomizer. The pressure of the fuel in the chamber 39 is dependent upon a spring 40 which can be adjusted by a screw 41. The turbine may have a low-pressure stage of increased diameter and driving a power consumer such as an aircraft propeller by a shaft passing through the main turbine and compressor rotor. The compressor-may also have an initial stage of increased diameter carried by the same shaft. The main turbine and compressor rotor is connected by gearing to the shaft and the arrangement is such that normally the gearing runs under no load.
