Title: A process for the preparation of artificial fibres consisting of a mixture of regenerated cellulose and a synthetic polyamino acid
IPC: D01F2/10
Filed: 1963-03-25
Abstract: 989,403. Regenerated cellulose polyamino acid mixture fibres. AJINOMOTO CO. Inc., and FUJI SPINNING CO. Ltd. March 25, 1963 [March 27, 1962], No. 11720/63. Heading B5B. Artificial fibres consisting of a mixture of regenerated cellulose and a polyamino acid are produced by wet spinning into an acid coagulating bath a viscose with which has been mixed an aqueous solution of a salt of a polyamino acid, the viscose having been de-aerated and ripened before the mixing step. The polyamino acid may be polyglutamic acid and the salt may be sodium, potassium or ammonium polyglutamate. The polyglutamic acid may be added to the viscose in the form of an aqueous hydrolysate solution formed by hydrolysing a poly-γ-ester of glutamic acid with an aqueous solution of an alkali metal hydroxide. The glutamate is preferably added to the viscose in such a proportion that the viscose contains 1 to 50% of polyglutamic acid based on the cellulose in the viscose. The concentration of total polymers in the viscose is preferably about 8% and the concentration of total alkali in the viscose (expressed as sodium hydroxide) is preferably 6%. The spinning process is carried out in the conventional manner for producing viscose rayon. Prolonged storage of the solution of polyglutamato in viscose should be avoided, as degradation of the polyglutamate occurs. In an example, a 20% solution of poly sodium glutamate (average molecular weight of the polyglutamic acid 77,000) is mixed with a conventional viscose which has been deaerated completely and ripened after 25 hours from the initiation of xanthation. The mixture contains 7.3% by weight of cellulose, 0.7% by weight of poly-sodium-glutamate and 6.2% by weight total alkali (as sodium hydroxide). The ammonium chloride value is 11.0 and the ball-fall viscosity 36À4 seconds. It is spun into a first coagulating bath maintained at a temperature of 45‹ C. and containing 106 grams per litre of sulphuric acid, 365 grams per litre of sodium sulphate and 15 grams per litre of zinc sulphate. The filaments formed are then drawn through a second and a third coagulating bath both maintained at 85‹ C. and both consisting of a 3% aqueous solution of sulphuric acid.

Title: Bottle-filling and stopper-applying machine
IPC: B67C7/00
Filed: 1925-05-12
Abstract: 245,655. Ross, K. A. B. May 12, 1925. Capsules and the like, applying. - A filling- machine combined with a stoppering-machine, having no turn-table in the path to the stoppering-machine, is characterized in that the bottle conveyer, between the filler and the stoppering- mechanism and beyond, initiates the operation of the stoppering-machine as soon as a bottle is placed on the bottle support, and at this stage the bottle is kept stationary for stoppering, the action of the conveyer 'being neutralized. Bottles B, Fig. 1, are removed from a filling-machine F by rotating arms into a slideway G where they are propelled by dogs M on a chain T. The operation of a stoppering-machine K is initiated by the conveyer T when a tappet d, Fig. 3, on one of the links of the conveyer chain strikes a vertically movable pin e connected to starting mechanism of the stoppering-machine K. The tappet d is brought into contact with pin e by a roller c moving over a cam surface b and dropping abruptly afterwards. At the same time a dog M moves backwards on the corresponding chain link and the bottle B is temporarily relieved for the stoppering interval and then moved on again by the same dog. Instead of, or in addition to, the cam b there may be wedge faces L which engage studs P on the links. In this case the pin e is situated behind the wedge faces. In another construction of dog, Fig. 5, the dog is not mounted directly on the chain but is supported through the intermediary of a spring 7 which extends temporarily. Bottles 1, Fig. 6, are propelled along a track 2 by dogs 3 driven by a chain 4. Connected to the chain is a holder 5 in the interior of which is fixed one end of a helical spring 7, Fig. 5, the other end of which projects into a tube 8 guided by a pin 9 entering slots 10 in guides 11 of the holder 5. Jointed to the holder 5 is a toggle arm 13 pivoted to another arm 14 pivoted to the tube 8. As the arms 13, 14 pass a stop 18, they are extended and the dog 3 is moved in che opposite direction to the chain 4 and the bottle remains at rest. The stoppering-machine may be that described in Specification 231,531, in which the bottle support has a part movable by pressure adapted to trip a latch holding a stressed spring, the unstressing of which allows the main clutch to be engaged. The tripping pin e will then be so arranged that it exerts pressure directly or indirectly on the bottle platform or on the tripping device of the spring which moves the main clutch into gear.
