Patent GB-242242-A (GB)
Title: An improved process for manufacturing artificial filaments film bands and the like from viscose
IPC: D01F2/06
Filed: 1925-09-08
Abstract: A soluble sulphide is incorporated with or formed in viscose to be used for the manufacture of artificial filaments, films, bands &c. By such addition the filament &c. is protected, on coagulation, by the deposition of sulphur or metal sulphide on the surface of and within the filament &c.  Suitable sulphides are alkali metal and ammonium sulphides, and the sulphides of arsenic, antimony and tin. The alkali sulphides may be used for the solution of xanthogenate. When the sulphides of arsenic, antimony and tin are used, these may be dissolved in alkali sulphide solution, optionally in the presence of caustic alkali, and the solution used for the solution of the xanthogenate; alternatively, the sulphides may be incorporated with the cellulose or at some other intermediate stage of the process, being finally brought to solution when the xanthogenate is dissolved, as by the addition of alkali sulphide, although such addition may be omitted if sufficient alkali sulphides are produced during the ripening process.  Specification 242,240 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the addition of the oxides or hydroxides of arsenic, antimony or tin; these may be dissolved in the caustic soda lye used for dissolving the xanthogenate, and during the ripening process they are in part or whole converted into sulphides.  This subject-matter does not appear in the Specification as accepted.

Title: Sealing and severing tubes of thermo-plastic material
IPC: B26D1/00
Filed: 1948-08-27
Abstract: 652,956. Packeting-machines. JOHNSON, W. T. Aug. 27, 1948, No. 22705. [Class 94(i)] In a machine for heat-sealing and severing filled tubes of thermoplastic material in which the sealing jaws form electrodes to which a highfrequency voltage may be applied and a motor drives through a train of gears a timing shaft controlling the opening and closing of the jaws and the opening and closing of the electric circuit, an axle adapted to carry any one of a variety of interchangeable pairs of toothed pinions each having a common hub is mounted on an arm pivoted to a fixed part of the machine so that said pinions may be brought into and out of engagement with respectively a pinion coupled to the timing shaft and a pinion driven by the motor, whereby by changing the pair of pinions the period of time during which the sealing jaws are closed may be varied. As shown in Figs. 2 and 3, a pair of pinions 26, 27 are rotatable on an axle mounted on a plate 18 which is secured to the machine frame by a lower stud and nut, forming a pivot, and a stud 21 passing through a slot 24 in the plate, the pinions being retained on the axle by a nut 29 and meshing respectively with a pinion 16 driven by the motor 12 and a pinion 30 on the timing shaft 31 which drives mechanism as described in Specification 652,955. By slackening the nut 23 on the stud 21, the plate may be swung about its pivot to disengage the pinions so that they may be replaced by another pair. The shaft 17 of the pinion 16 drives through worm and wheel gearing a hub 34, Fig. 5, forming one element of a slipping clutch of which the other element 36 is secured to a shaft 35 and normally prevented from rotating by a stop 38 on a lever 39, Fig. 4, urged upwardly by a spring 43. The opening of the sealing jaws effects downward movement of a pawl 41 engaging a rack 42 coupled to the lever to move the stop 38 out of engagement with a pawl 37 on the element 36 so that the shaft 35 makes one complete revolution while the jaws are open. An arm 44 on the end of the shaft is coupled through a connecting rod 45 and crank 46 to a quadrant 48 meshing with a gear 49 which drives through a one-way clutch 51, 52 a shaft 50 coupled by a dog-clutch 54, bevel gearing 56, shaft 57, bevel gearing 58 and spur gearing 62-65 to the rollers 60, 61 which feed the tubes through the sealing jaws. The position of the stud 66 by which the rod 45 is pivoted to the arm 44 is adjustable by a micrometer screw 67 to vary the length of tube fed by the rollers during each period that the jaws are open. The -rollers may be rotated manually by means of a hand-wheel 69 which is pushed in to engage a clutch 70 and disengage the clutch 54.

The pipes 7, 26, the gooseneck assembly and the reservoir assembly 17 are surrounded by refractory material containing electric heating elements. A gasholder 58 maintains an inert gas pressure above the metal in the wall 43 and the reservoir 17. In operation, when the level of the metal in the well is the same as that in the reservoir, the level detector 30 causes the valve 9 to be closed, the piston 45 is drawn upwardly by piston 51, and the ports 42 are covered, allowing metal to enter the shotcylinder, lowering the level in the well and causing metal to flow from the reservoir and causing the level-detector to open the valve 9 to restore the level in the reservoir. Downward movement of the piston 45 forces metal into the die and after solidfication of the casting, the die half 68 and casting are withdrawn, the piston 45 is drawn upwardly, and molten metal recedes in the nozzle 37 to a level corresponding to that in the well 43, just below the outlet 64. Dripping is thereby obviated and only a small quantity of contaminating air enters the die ahead of each shot.
