摘要： Apparatus for making filaments-Relates to means for supplying additional air or other evaporative medium in the vicinity of the spinning jets when dry spinning artificial silk &c. as is described in the parent Specification. According to one modification, such air is supplied to the interior of the bundle of filaments issuing from the spinning jets. The air may be supplied through the body of the spinning nozzle as in the form shown in Figs. 1 and 2, or if a gap is left in the ring of spinning orifices constituting the nozzle then as shown in Fig. 5 in which a disc jet is employed, a separate pipe 41 may serve for the air supply, the pipe being pivoted to the nozzle pipe 28 and a stop 44 being provided to determine its movement. In the former case the spinning jet 16 is of annular form, being held in position together with a section of filter cloth 15 and appropriate packing 17 by means of an external collar 19 and an inner member 25 screwed to the body 7 of the nozzle; this outer member serves for the supply of the additional air, for which purpose air supplied through a pipe 231 and a passage 22 in the body 7, passes through a passage 24 in the member 25, then through inclined radial passages 24a into an annular space from which it is distributed by means of an adjustable spreader 26. The additional air may be directed with respect to the filaments either downwardly, upwardly or radially outwards, but preferably in the direction of movement of the filaments and somewhat outwardly. The devices above described may be used in conjunction with devices for supplying additional air to the exterior of the bundle of filaments. According to another modification, applicable to cases in which the filaments are extruded into a counter current of the evaporative medium, the additional air &c. introduced in the vicinity of the jets, is constrained by the provision of a tubular or other collector device that surrounds the filaments, to make intimate contact therewith; the additional air may move in the same direction as the filaments, or opposite thereto. As shown in Fig. 8 an external perforated ring 53 serves for the supply of additional air which is directed upwards and inwards, and a collector 48 causes this air to make intimate contact with the filaments during its passage to the draw-off pipe 50. Instead of the ring 53, the additional air supply device may be combined with the spinning nozzle as shown in Figs. 1 and 2. In another form shown in Fig. 9, the collector 56 is mounted on the filter 30, and additional air is supplied downwardly through a perforated pipe 58, the air moving downwardly with the filaments before passing to the draw-off 50. The amount of additional air may bear any relationship to the total volume passing through the cell, and it is preferred that the supply is controlled in the manner described in Specification 203,092 [Class 2 (ii), Cellulose &c], and employed in respect of the drawoff from the cells. The additional air may be cold or heated; and it may contain a proportion of solvent vapours.

摘要： Artificial filaments, ribbons, and like materials are obtained by downward extrusion into an evaporative atmosphere, the rate of flow of which is controlled over a part of the path of the filaments extending for a short distance from the nozzles, in which part setting of the materials is initiated, while the remaining and greater part of the path, wherein setting is completed, lies in the open air or in large chambers such that the materials are readily accessible. The filament-forming substance may be cellulose acetate or other cellulose ester or ether. The evaporative atmosphere is preferably heated. Separate streams of air in the region of each nozzle or each pair of nozzles may be effected by arranging suction or injector devices adjacent each nozzle or pair of nozzles and the flow is controlled by valves, iris diaphragms, or other devices together with flow meters. The flow of air may be in any direction with respect to the filaments. The suction or injector device may be arranged above or at the side of the nozzle or in the case of orifices arranged in ring formation, it may be at the centre. The air may be heated by steam pipes or other devices adjacent the spinning nozzles or surrounding the supply ducts. High air temperature leads to the production of hollow filaments, but for lustrous filaments of round cross-section the spinning solution should be hotter than the air. Each spinning nozzle may be surrounded by a sleeve which may be adjustable along the filter-candle or pipe carrying the solution to the nozzle. The sleeve may be telescopic and may be heated. The temperature of the air of the spinning room may be raised. The spinning room should be efficiently ventilate in view of the large quantities of solvent evaporating therein. The filaments, after travelling through the air of the room, are received on bobbins, or swifts, and may be twisted by ring or cap spinners. They may be stretched during the open air travel, if desired after the application of softening agents, and the tension may be restricted to the plastic zone. The filaments may be caused to adhere so as to form artificial horse-hair or straw. The spinning solution may have a high or low proportion of the cellulose ester or ether and may contain diluents, pigments, and other additions. As shown in Fig. 1, filaments 11 extruded from jets 8, pass for a short distance through a space 9 through which evaporative medium is caused to flow at controlled velocity. The space 9 is shielded from the surrounding atmosphere, and heated by fluid circulating in jackets 12. Flow of air is effected by means of a central suction conduit 13 with connection to the space around the filters 7 and jets 8 by apertured diaphragms 16. The air is provided from the open air at the bottom of the zones 9 or it may be admitted through nozzles 17 or 20. The filaments pass from the zones 9 and travel over a long path in the open air to complete their setting and evaporation of solvent. They may then be passed over stretching bars and rollers and collected on cap spinning devices. As shown in Fig. 2, the filters 37 are mounted in a casing 38 incorporating a duct 39 and heating jacket 40. Around each spinning jet 41 is a hood 42 enlarged at its lower end 44. Air is supplied at constant pressure to the conduit 39 and discharged through a diaphragm 45. Heated air escaping from the hood 42 is carried away by means of a hood 47 connected to a suction conduit 48. The filaments pass on through the open air and are collected, if desired after being lubricated, on a ring spinning device. As shown in Fig. 4, the filter casing consists of a tubular member 57 of a heating unit comprising jackets 58. The lower end of the tube 57 is closed by a cap 63 carrying the jet 64. The spinning zone comprises a hood 65 provided with heating pipes 66. A flow of air through the hood is maintained by a suction conduit 67 common to a number of hoods and connected to each by a pipe and diaphragm 69. The filaments are given a long air path during which they are stretched by passing round rollers 70, 71 rotating at different speeds. They may be stretched between the jet and the first roller as well as between the rollers. They are wound on a bobbin 72. As shown in Fig. 5, an upward current of air towards the jet is produced by a suction conduit 74. The pipe 78 is connected to the centre of an annular jet. A casing 81 with heating jacket 82 is provided near the jet. Air is also supplied through a perforated ring pipe 83.

摘要： Artificial filaments, threads, yarns, ribbons, films, and the like of reduced lustre are obtained by spinning a solution of cellulose or a cellulose derivative, which solution contains a substantially white ketone-aldehyde condensation product. A suitable condensation product is obtained by condensing one molecule of acetone with six molecules of formaldehyde in the presence of aqueous caustic soda. The formaldehyde may be replaced by its polymers or condensation products, e.g. paraformaldehyde and hexamethylnetetramine. The condensation product may be incorporated in the spinning solution together with other organic or inorganic pigments, for example, the condensation product and pigment may be ground together, or the condensation product may be formed in the presence of one or more of the other pigments. The process is applicable to the cellulose organic ester or ether, cellulose nitrate, viscose, or cuprammonia processes. In an example, the product obtained by condensing 100 parts of 30 per cent formaldehyde with 10,1 parts of acetone in the presence of aqueous caustic soda, is ground in oil and incorporated in a cellulose acetate spinning solution in proportion 2 per cent on the weight of cellulose acetate. The solution may be spun by dry or wet methods. Specifications 326,461, 326,462, 328,247, 333,504, 334,195, [all in Class 2 (ii), Cellulose &c.], 346,678, and 346,793 are referred to.

摘要： Apparatus for making filaments.-The evaporative medium is constrained to pass the vicinity of the spinning orifices solely by means of suction applied to withdraw the evaporative medium from the cell, e.g. a draw-off device of the type described in Specifications 300,998 and 326,232, serves as a collector device. Additional evaporative medium may be introduced in the vicinity of the nozzle as in Specification 325,233, [Class 2 (ii), Cellulose &c.], further the draw-off device may be combined with the nozzle body and the additional evaporative medium may be introduced through the face of the nozzle in a manner similar to that described in Specification 341,075. The draw-off device comprises a perforated or slitted pipe arranged around the nozzle and corresponding in form thereto. Fig. 1 shows a ring-type nozzle 10 surrounded by a draw-off device 14 comprising a tubular ring with slits or openings 15. The device 14 is arranged at or slightly below the level of the nozzle, the openings 15 being so directed as to induce a flow of air close to the filaments 11. Fig. 3 shows a device in the form of a hood 19 mounted on the filter candle 21 and fitted with a draw-off pipe 20. Fig. 4 shows a draw-off device 14 associated with a collector in the form of a perforated plate 24 and with a tubular ring 22 for introducing additional evaporative medium. Fig. 5 shows an example of combined air-introducing and draw-off means associated with the nozzle body. Spinning solution supplied through a pipe 25 passes through passages 26 in the nozzle body 27 to a cavity 28 fitted with the nozzle 10. Air is admitted through a pipe 33 and passage 34 to a central cavity 32 and emerges through the hollow screwed member 30. A suction cavity 36 surrounds the jet and is furnished with a slot 39 near the level of the jet face and a drawoff pipe 35; the right-hand half of the figure shows the cavity 36 integral with the body 27, while the left-hand side shows the cavity formed in a cup 38. Further modifications are described. Specification 203,092, [Class 2 (ii), Cellulose &c.], also is referred to.

摘要： 300,998. British Celanese, Ltd., Kinsella, E., Bower, J., Taylor, W. I., and Dreyfus, H. May 23, 1927. Apparatus for making filaments.-When dryspinning artificial silk, &c., particularly by the downward spinning method, the full evaporative effect of the air or other gaseous medium is obtained by providing the spinning cell or chamber with collector devices of such a construction that either the whole of the evaporative medium, or a part of such medium, is constrained to pass within the immediate vicinity of the spinning nozzle and preferably to impinge on the nozzle face. The collector device may be formed by tapering the spinning cell towards the spinning nozzle; or it may consist of a plate having a hole or holes corresponding with the spinning nozzle or nozzles, and mounted at a slightly lower level in the cell; or it may consist of a hood or inverted funnel or bell-shaped member 1, Fig. 1, mounted below the spinning nozzle 3 and supported, e.g., by means of flexible wires suspended from pullies ; or a funnel-shaped member 11, Fig. 4, mav be employed, the member being capable of sliding on the pipe 13 leading to the nozzle 14 and being fixed in position by a spring clip 17 ; in this last construction, a branch pipe 15 connected to the upper part of the member, which may be of spherical shape, serves for the withdrawal of the evaporative medium; another alternative form of collector comprises a cylindrical member 18, Fig. 5, mounted on the supply pipe 20 and carrying the outlet for the evaporative medium, and a second cylindrical member 19 capable of telescoping on the first member, the evaporative medium entering through the restricted mouth 25 of the latter or through a perforated plate fitted in the mouth, even distribution of the medium being assisted by a perforated flange 27 above the nozzle; or a heating device 40, Fig. 7 may be combined with the collector 37, in which case the part 42 carrying the outlet pipe 43 is a sliding fit in a flange 41 formed on the collector and is held on the supply pipe 45 by a clip 44. As an alternative to the means above described, the means for withdrawing the evaporative medium may comprise one or more downwardly extending tubular members, preferably situated immediately above the nozzle or nozzles, one for each; alternatively, the withdrawal means may comprise a pipe of annular form surrounding the nozzle and provided with perforations, slits, or continuous slits, this arrangement being particularly applicable to the ring type of nozzle although it may be used with the disc type, as shown in Fig. 8 in which the perforated ring-shaped pipe 52 is mounted immediately above the nozzle 49, the collector comprising in this case an inverted funnel-shaped member 51, in which a tubular part 50 is slidably mounted ; and the branches for carrying off the evaporative medium from the several cells or nozzles are preferably provided with valves, constrictions or other regulating devices, with or without flow meters as described in Specification 203,092. By the use of the collector devices, a stricter control is obtained over the cross-section of the filaments, which by suitable adjustment may be of flat, semi-flat, or rounded section. Specifications 165,519 and 198,023 also are referred to.

摘要： 326,232. British Celanese, Ltd., Dreyfus, H., Kinsella, E., Bower, J., and Taylor, W. I. Dec. 7, 1928. Addition to 300,998 and 304,674. Apparatus for making filaments. - The process and apparatus of the parent Specifications are modified by providing in conjunction with a spinning nozzle comprising a. line of extrusion orifices, a collector device or devices having a shape appropriate to the shape of the nozzle and adapted to limit the passage for the evaporative medium so that substantially the whole or a definite proportion is constrained to pass through the immediate vicinity of the spinning orifices. Collector devices according to the invention may be used with nozzles having a rectilinear, arcuate, or other curvilinear arrangement of orifices, or with nozzles comprising two or more lines of orifices forming an enclosed or partially enclosed figure. The collector devices may be hoods, funnels, cylinders, shields, or perforated plates, and may be directly connected to the exhaust for the evaporative medium. In Figs. 1 and 2, two line nozzles are employed. The collector device comprises an apertured plate 17 and a pair of movable plates 18 which leave apertures 19 through which the filaments pass, and the evaporative medium is constrained to pass through the immediate vicinity of the nozzles 16 on its way to the drawoff device 21. In Fig. 3, collector devices are shown for employment with arcuate line nozzles, an apertured plate 22 co-operating with movable plates 23 to leave apertures 24. In Fig. 7, a ring nozzle 37 is employed in a cell 38. A collector device comprising a plate 40 having an aperture conforming with the shape of the ring 37, is secured in the cell at about the level of the ring 37, leaving a gap 41. The interior of the ring may be closed by a plate 42 or a cone 43, or an annular gap may be left. In Fig. 9 a ring nozzle 46, with collector device 47 or 48, is provided with a hood-like collector device 49 downwardly extending from the filter chamber 50 and connected by a. pipe 51 to the exhaust for the evaporative medium. Instead of the whole of the evaporative medium being taken through hood 49 and pipe 51, a portion may be allowed to pass outside the hood 49 and through exhaust device 53. In Fig. 10 a funnel-shaped collector device 54 of cross-section corresponding to the shape of the line nozzle 55 is supported by a perforated plate 56, and its position is preferably adjustable. There is also provided a draw-off device comprising a pipe 58 perforated or slotted on its under surface as shown at 59 and shaped to correspond with the form of the nozzle. The collector device 54 may be heated electrically or be provided with an air, steam or hot-water jacket. The collector devices described above may be used in cells open or closed at the end remote from the spinning nozzle, and containing a small or large number of line nozzles. Specifications 165,519, 198,023, and 203,092 are referred to.

摘要： 322,778. British Celanese, Ltd., Bower, J., and Yorke, W. July 12, 1928. Channels and reservoirs in rotary pumps.-In a process for pumping artificial silk spinning solutions, the bearings of the pump are lubricated by causing a portion of the solution being pumped to flow from the delivery side of the pump to the inlet side via the bearings. As shown in Fig. 1. wherein the shafts 4, 7 of a gear pump run in journal bearings 5, 6, 8, 9, spinning solution flows from the delivery side of the pump to the bearings 5, 6 through channels 20 formed in the casing cheeks, and is carried outwards along the bearings by spiral grooves 16, 17. From the outer ends of the bearings the solution fows through passages 14, 15 to the bearings 8, 9 and is carried inward by spiral grooves 18, 19 to channels 22 in the casing cheeks communicating with the inlet side of the pump. The channels 20 may be replaced by passages, controlled by needle valves, leading to annular grooves in the bearings 5, 6. Where the gear shafts run in ball or roller bearings 5, 6, 8, 9, Figs. 4, 5, and 7, mounted in chambers 10 - - 13, solution passes to the chambers through passages 20, 21 communicating with ports 15 in the casing leading from the delivery side of the pump, the ports being controlled by needle valves 17. The solution passes from the bearing chambers through passages 24, 25 communicating with ports 23 leading to the inlet side of the pump. The passages leading to and from each bearing chamber are arranged on opposite sides of the bearing and are separated by a relatively-large circumferential distance. In a slightly-modified arrangement, the Bow of solution to each bearing chamber may be adjusted independently.

摘要： 304,674. British Celanese, Ltd., Dreyfus, H., Kinsella, E., Bower, J., and Taylor, W. I. Oct. 24, 1927. Addition to 300,998. Apparatus for making filaments.-The cells for dry spinning artificial silk &c. described in the parent Specification may be modified in that they may contain an increased number of nozzles up to 100 or more, so that it is no longer necessary to partition the '' metiers " of the spinning plank into comparatively small cells. These cells and those of the parent Specification may further be open at the ends remote from the nozzles. In the form of apparatus shown in Figs. 1 and 2, each cell 1 contains two spinning nozzles 2 and a collector device 3. The bottom of each cell is open and the air drawn from the spinning room is heated, for instance by the coil 5 located inside the cell, and then led by the collector devices through the immediate vicinity of the nozzles 2 and drawn off by way of tube 6 through valves, constructions, or other regulating devices, with or without flow meters, as described in Specification 203,092. The filaments 11 are led through the open bottom of the cell to a godet 12 but may be led through openings in the wall of the cell. In the modification shown in Figs. 3 and 4, the cell contains a relatively large number of nozzles 2, each of which is provided with a collector device 14, 15. The evaporative medium is drawn off through the annular pipe 16 perforated on its under side. In Figs. 3 and 4 the bottom of the cell is open but in order to direct the incoming air in a substanitally vertical direction and to distribute the air evenly over the length of the cell, the bottom may be partly closed by a plate 20 leaving apertures 21, tubes 22 being inserted into the apertures, as shown in the bottom lefthand side of Fig. 4. The longitudinal walls of the cells may be provided with upwardly extending fins 23 to guide the air towards the collector devices. Heating may be effected by pipes 24 and the collector devices may be heated by pipes 25. In the apparatus shown in Fig. 5, each cell 26, the bottom of which is closed, accommodates 4 or other relatively high number of nozzles 2, the nozzles being arranged in pairs to form two rows along the length of the cell. The evaporative medium is drawn into the cell 26 through pipes 27 arranged along the length of the cell and controlled by valves 28 from trunk 29. The outlet from each collector device 31 may be separately controlled but it is convenient to connect the collector devices serving pairs of nozzles to a single draw off pipe 6. Downward extensions 33 may be provided to the collector devices and the relatively large chambers containing a large number of nozzles may be fitted with partitions, which extend for only a part of the total height of the chambers and separate off each spinning nozzle or small grouping of nozzles, such partitions being in effect merely extensions of the collector devices. Specifications 165,519 and 198,023 also are referred to.
