Patent GB-696609-A (GB)
Title: Improvements in the production of textile materials by the viscose process
IPC: D01F2/08
Filed: 1951-06-18
Abstract: The concentration of lead in viscose spinning baths containing sulphuric acid, and circulating through a system having walls lined with or consisting of lead, is reduced or kept at a low value by co-precipitating lead sulphate from the spinning bath with barium or strontium sulphate by adding to the bath, outside the spinning zone, a barium or strontium compound capable of reacting with sulphuric acid in the bath to form a sulphate. Water-soluble compounds of barium or strontium are preferred, e.g. barium or strontium chloride, barium oxide or hydroxide, and strontium nitrate or acetate, but a suspension of barium carbonate may also be used.  The barium or strontium compound is preferably added under such conditions that a very finely-divided precipitate of the sulphate is formed, e.g. the bath being vigorously agitated and maintained at between about 35 DEG and 55 DEG  C.  In an example, a 25 per cent solution of barium chloride is continuously added for 48 hours at a rate of about 5.3 c.c. per minute to 1000 U.S. gallons of a viscose rayon spinning bath, (circulated at a rate of about 6.3 gallons per minute at 50 DEG C.), the lead content of which in use has attained an equilibrium value of about 6.7 parts of lead per million.  The solution is added immediately after the bath has left the coagulating zone, and the precipitate formed is allowed to agglomerate and settle out; any precipitate remaining in the supernatant liquid is filtered off during the further circulation of the bath before it is returned to the coagulating zone.  A 12.5 per cent barium chloride solution is then added at a rate of about 10.6 c.c. per minute for a further 24 hours and finally a 6.25 per cent solution at the rate of 21 c.c. per minute for about one week.  The lead content of the bath is then found to be stabilized at about 0.6 p.p.m.  Similar examples are given using barium hydroxide and strontium nitrate respectively.  In the latter case the addition of 140 lbs. of strontium nitrate per hour reduces the lead content of the bath to about 3 p.p.m. or less. The colour of yarn produced with spinning baths treated according to the invention is improved and the special washing procedures otherwise required to remove yarn discoloration due to lead are rendered unnecessary.

Abstract: 290,639. Jagenberg-Werke Akt.-Ges. May 18, 1927, [Convention date]. Filling cigarettes into boxes.-Cigarettes of oval cross-sections are inserted in boxes in layers, and, before filling, those cigarettes of the top layer which are lying with the wrong side uppermost, are turned through 180‹ so that the inscriptions thereon all face the same way. The boxes 1, Fig. 1, to be filled are passed along a shoot 2, a dust sheet 3 is inserted at position A, a first layer of cigarettes at 13, and a sheet of cardboard 5 at C. A filling plate 6, Figs. 1 and 6, is temporarily inserted at D, and the top layer of cigarettes, after adjustment, is inserted from a rotary table 9. The cigarettes are fed from between the vertical walls 14 of a hopper 8, Fig. 3, by slides 15 into sleeves 10, mounted in series on the table 9. The bottom plate of the hopper 8 is ribbed and is transversely movable to arrange the cigarettes into a uniformly inclined position prior to insertion in the sleeves, which have inclined admission apertures, and inspection holes 17. After the first movement of partial rotation by the table 9, the charged series of sleeves arrives opposite a turning device 11 comprising an adjustable carriage 19, by moving which blades 21 can be made to engage with slots 33 on the ends of the sleeves. Each sleeve in which the cigarette is wrong side uppermost is rotated through 180‹ by depressing the corresponding spring key 26 to rotate the blade 21 by bevel gear. The adjusted batch of cigarettes subsequently arrives opposite an ejector 12, which pushes the cigarettes into a series of displaceable sleeves 13, Fig. 4. On moving the sleeves 13 from the position shown in Fig. 4, to that in Fig. 3, the engagement of pins 30 in radiating slots 31 causes the sleeves to approach each other. Stationary plungers 34, Figs. 3 and 6, eject the cigarettes on to the filling plate 6 placed obliquely in the box 1, the ends 35 of the sleeves being cut away to permit tilting. The plate 6 is removed at position E, Fig. 1, and the box is conveyed by a device 7 to closing, covering, or labelling apparatus. In a modification, the sleeves 13 are made to cooperate with an inserting member having spring held walls between which the cigarettes are left after the withdrawal of the sleeves, and the walls are then opened to place the cigarettes in the box.

Title: A process for the manufacture of compressed carbide bodies
IPC: C10H21/00
Filed: 1935-05-22
Abstract: Carbide cakes, particularly suitable for use in drip-feed acetylene generators, are made by heating granulated carbide to 100--150 DEG C., impregnating it at that temperature with a viscous hydrocarbon oil, then adding at about the same temperature a fusible binding medium which is soluble in or miscible with the hydrocarbon oil, and finally compressing the mixture.  Suitable binding media are sulphur, pitch and asphalt.  The viscosity of the hydrocarbon oil, which may be tar oil or paraffin oil, may be reduced by addition of a less viscous mineral oil such as petrol or lamp oil.  Substances such as sugar, alkalies or lime may be mixed with the carbide before it is impregnated.  The cakes are preferably made in the shape of cylinders provided with one or more tubular channels in which water-distributing devices, e.g. metal gauze tubes, perforated sheet-metal members, or paper cartridges, may be embedded.
