Patent GB-717156-A (GB)
Title: Spinning artificial filamentary materials
IPC: D01D5/08
Filed: 1952-11-20
Abstract: <PICT:0717156/IV (a)/1> <PICT:0717156/IV (a)/2> Dry-or melt-spinning apparatus comprises a spinning cabinet, a spinning jet, a streamlining device surrounding the jet, and means for preventing the entry of gaseous coagulating medium into the spinning cabinet at its end nearest the jet except through the streamlining device.  The latter comprises an annular passageway or passageways, each of which has a cross-sectional area substantially constant throughout its length, and surrounds and is coaxial with the spinning jet and has its output end at approximately the level of the jet face.  As shown in Fig. 1, artificial filamentary material 13 is extruded from the spinning jet 12 into the open-topped spinning cabinet 14 from which air may be exhausted at a point remote from the jet 12.  A stream of air is thus caused to enter into the top of the cabinet 14 through the annular passageway 21 between the flared upper end 17 of the wall of the streamlining device 15 and the frusto-conical sleeve 19 supported on fins 18 inside and coaxially with the member 17. The sleeve 19 extends approximately to the level of the face of the jet 12 and is inclined at a somewhat greater angle to the vertical than is the member 17, so that the cross-sectional area of the passageway 21 remains constant throughout its length and is preferably about equal to that of the body of the cabinet 14.  The space between the spinning head 11 and the sleeve 19 is sealed against the flow of air by means of a packing 22.  As shown in Fig. 3 there is supported within the frusto-conical sleeve 39 of the streamlining device 35 by means of a number of fins 45 a hollow-walled frusto-conical member 42 through which a heat exchange medium may be passed by means of conduits 43 and 44.  The member 42 forms with the sleeve 39 an annular passageway 46, narrower than the main passageway 41 between the sleeve 39 and the outer wall 37 of the streamlining device 35, through which an additional quantity of air, whose temperature is controlled by the heat transfer medium, may flow to the spinning cabinet 34.  The cross-sectional areas of the passageways 41 and 46 are constant throughout the length of the passageways, and the sum of the cross-sectional areas is approximately equal to that of the spinning cabinet 34.  The lower edges of the sleeve 39 and the member 42 are curved as at 47 in such a manner that the stream of air flowing through the passageway 46 will be directed transversely across the face of the jet 32.  The space between the spinning head 31 and the member 42 is sealed by means of a packing 48.  The cross-section of the spinning cabinet 14 and 34 may be circular, square or rectangular..  The apparatus of the invention renders it possible to introduce the coagulating medium into the spinning cabinet in a substantially non-turbulent condition and thus substantially eliminate irregularities in filamentary materials due to turbulence of the medium in the vicinity of the spinning jet.

Patent GB-675001-A (GB)
Title: Improved sisal wax and method of producing the same
IPC: C11B11/00
Filed: 1949-11-17
Abstract: Sisal wax is separated from the sisal leaf by contacting the leaf with a solvent for sisal wax whilst the leaf retains its original fibre structure and its aqueous pulp in uncrushed form. The fibre may then be separated from the leaf in the usual decorticating drum, the leaf being preferably sufficiently hot to be limp during this treatment, which condition may be brought about by using a solvent heated to at least 50 DEG C. in the wax extraction.  The solvent is preferably anhydrous and immiscible with water.  Chlorinated hydrocarbons are preferred and the following are specified: trichlorethylene, perchlorethylene, and carbon tetrachloride.  The solvent may be used heated and preferably in the vapour form, at or above its boiling point.  An open or closed tank may be used for the extraction, in the latter case with reduced or increased pressure. An open, vapour-degreasing tank is preferred, equipped with a heater for the solvent in its lower part and with a cooling coil at its rim, thus forming a vapour zone between the solvent and the top of the tank wherein the leaf is suspended vertically or inclined to allow the condensed solvent thereon with its dissolved wax to drip into the tank.  The solvent is preferably of boiling point below 100 DEG C. so that its vapour does not vapourize the water of the sisal leaf. The wax is then recovered from the solution, after filtering, in a conventional vaporizing and solvent recovery apparatus.  A wax of lighter colour and containing less impurities is obtained than in the usual extraction from the dried sisal pulp freed from the fibres. The wax may then be refined to remove the remaining colour, fatty oils, and resins.  The decolorizing may be effected with adsorbents by treating the molten wax either with a mixture of activated clay and activated carbon or with lignin whilst heating, followed by filtration.  Chemical decolorizing agents may be used in addition or alternatively, such as sodium hypochlorite, bleaching powder, organic peroxides such as benzoyl peroxide, inorganic peroxides, and sulphuric acid.  The fatty oils may be removed from the crude wax by means of acetone, higher boiling ketones, diethylether, or higher boiling ethers at room temperatures, which dissolve the fatty oils leaving the wax with its resin impurities.  After filtration the wax is treated to remove the latter by means of hot alcohols, such as methanol, ethanol and isopropanol, in which the resin impurities are insoluble.  The solution of wax in the solvent is then separated and cooled to room temperature or lower to precipitate the purified wax.

Title: Loading device for machine working on tubular workpieces
IPC: B29C31/06
Filed: 1963-07-25
Abstract: 1,049,655. Machine tool details. L. HAUF. July 25, 1963 [July 28, 1962], No. 29500/63. Headings B3B and B3N. [Also in Division B5] In a loading device operating with a moulding machine a loading rod 16 is aligned with a tube holder 26 and a workpiece c is dropped thereon, the rod 16 being mounted for rocking motion about an axis 14 and carrying a stop 17 against which acts a spring 17a connected to a pusher block 18, said pusher block 18 having V-shaped camming surfaces which co-operate with V-cams 20 mounted on a member 13 which is vertically movable by means of rod 13a and slider or guide rods 12. As the rod 13a is moved upwards the cams 20 cause the block 18 and consequently the rod 16 having on it a workpiece c to be moved out of alignment with the tube carrier 26 and into alignment with a cylindrical guiding member in the form of a mandrel 4, the tube c being pushed on to the mandrel by the continued upward movement of member 13 and pusher block 18 until tube c contacts shoulders 4b, when the member 13 is lowered. The tube is retained on the mandrel by friction between collars 4c, 4d. The rocking movement of block 18 causes a lever 24 to be rocked about axis 23 such that a finger 24a is withdrawn from a hole in tube 26, and a finger 24b inserted in a hole lower down said tube, thus allowing a workpiece c to drop down said tube on to finger 24b. Thus, as member 13 is lowered and rod 16 moved back into alignment with tube holder 26, the lever 24 is rocked and finger 24b withdrawn and 24a inserted into said tube holder 26, thus allowing a tube c to fall on to the rod 16. Screwing-up devices.-An indexing device 5. Fig. 1 (not shown), serves to drive shaft 2, disc 3 and mandrels 4 step-by-step around a vertical axis to bring the mandrels 4 in successive working positions opposite devices 6, 7, 8, 9 and 10, the axes of which are also vertical and coincide with those of mandrels 4. The device 9 serves to screw a tube cap on to the tube head and the device 10 removes the finished tube from the mandrel 4, said tube being blown into an opening 63 in the upper plate of the machine frame.

Title: Process for the production of 1,4-cyclohexanedimethylene-bis-chlorocarbonate
IPC: C09D167/06
Filed: 1963-07-26
Abstract: The invention comprises trans- and/or cis-1,4-cyclohexanedimethylene -bischlorocarbonate, which may be made by reaction of 1,4-cyclohexanedimethylol with phosgene. A mixture of trans-and cis-1,4-cyclohexanedimethylol is introduced into liquid phosgene and a mixture of the trans-and cis-chlorocarbonates is formed. After a short time trans-1,4-cyclohexanedimethylene-bis-chlorocarbonate crystallises out and the liquid cis-form may subsequently be obtained from the solution by evaporating the phosgene. The two isomers may be saponified with water or alkali to form very pure isomeric 1,4-cyclohexanedimethylols, or may be reacted with alcohols, amines and phenols to form esters of carbonic acid and of urethanes.  A detailed example is given.
