Definitions

  • My present invention pertains to apparatus for the production of masses or solutions free from air and other gases, and particularly those employed in the manufacture of artificial threads, films or other articles.
  • the material For the production of' artificial articles, such as threads or films, from cellulose and other solutions, the material must be freed of every trace of air in suspension, because otherwise, when the material, interspersed with air bubbles, passes out of the spinning nozzles, or the apertures of the pourer, the threads will break, or films with air bubbles will be formed. It is also injurious-for the material to contain an excess of gases or volatile solvents. For instance, anexcess of free ammonia 1n cupric oxid-ammonla-cellulose solutions produces a weak thread of gray appearance, while free carbon disulfid in a viscose solution has an unfavorable action on the solution itself and on the coagulation of the same.
  • This invention pertains to an apparatus by means of which the material can not only be absolutely freed in a simple manner of air and objectionable vapors, receptacles and spinning tube, but which also renders it possible to recover the excess of the solving or gelatinizing agent, and is based on the following observations:
  • the receptacle 1 contains a material which, in order to insure perfect homogeneity, has been prepared with an excess of solving or elatinizing agents, or to which some indifferent and, if possible,
  • the cocks .O and O highly volatile solution e. g., sulfuric ether in case of viscose material
  • filters 1 and 1 denote filters, interposed between receptacle 1 and the receptacles or chambers 2 and 3, from which latterthe material, after the valves 4 and 5 have been opened, passes into the supply pipefi, and
  • the vacuum pipes 15 and '17 lead to the vacuum chamber C, which is provided with an observation glass C, while the main vacuum pipe 17 extends from the chamber C and is connected to coils or manifolds 23, in the preheater 22.
  • the coils 23 are capable of being heated by hot water or steam introduced through the inlet 24.
  • 25 is the exhaust for the steam or water.
  • 26 is the connecting ipe leading to the vacuum.
  • pump 27, whi e 28 designates the connecting pipe leading to the condenser 29.
  • 30 are the cooling coilsin the condenser, to which the cooling medium is admitted at 31, the same passing out at 32. The con densate is drawn off at 33.
  • the discharge cock of the receptacle which is being emptied is preferably closed while some of the material is still left in said receptacle in order that no air which is in the receptacle above the material may be able to enter the supply pipe 6. Any compressed air contained in the receptacle is then allowed to escape. Thereupon, the re ceptacle is exhausted by means of a vacuum pump, and as soon as the vacuum-meter indicates a suificient vacuum in the receptacle the admission cock 0 is opened, while 0' o the other receptacle is closed. The material spreads, as described above, over the deflector B, in a thin layer or film and is completely freed of air.
  • the cock 7 or 8 When it becomes necessary to renew the filtering material in one of the filters 9 or 10, the cock 7 or 8,"respectively, is closed in order to shut off the supply of material to the filter.
  • the cook 7 or 8, respectively, is
  • the gases sucked out by the vacuum pump are preheated, if required, in the preheater 22, and as they are practically free of air they may be regenerated in the original form by condensation in the condenser 29.
  • regeneration of the gases may be effected by different means, a. by absorption and distillation, without affecting the character of the invention.
  • the receptacles 2 and 3 are fitted with cooling jackets or cooling coils through which a cooling medium is made to pass, or any other suitable cation Serial No. 186,036, filed August 13,
  • a receptacle adapted to contain a supply of material; a pair of chambers; a filter located between each of said chambers and the receptacle; means contained within each chamber for filming the mass as it passes thereinto; a.
  • spinning system connected to said chambers; and means for exhausting the air from said chambers and said system.
  • a receptacle adapted to contain a supply of material
