Definitions

  • the apparatus according to l'lll, invention renders it possible to'cblain a (tillth'tttlllllllS tion, without it being ncct try to smaller-quantities oi substances than Chose used with theold liicbig methcia.
  • .'lliis prol lem is s lved by inserting with a light joint the cnnbustiou pipe proper into a sound. wider pipe. also charged with copper oxitl copper coils or the like. through which the gases escaping from the. last absorption tube. are sent for completing th combustion.
  • Th apparatus is schematically shown in the acc: nipanying drawing. in which-- Figurc 1 shows an apparatus embodying the present invention. and big. 2 show a modified form of :u iparatus.
  • i la calcium chlorid pipe c and a soda-lime pipe (I til desired a Deustacdt swan neck) is connected in the usual nainner to the combustion pipe (1,.
  • the escaping carbon mouoxid and the carbonic acid which has not been absorbed. are returned through a connecting pipe 71.
  • pret'erabl surrounded by a protecting metal tube not shown in the drawing. to the front portion of the outer or jacket pipe 7), in order tobe completely burned while passing therelhrough, and to be absorbed in the soda-lime pipc when escaping from the pipe (2.
  • f is a straight calcium chlorid pipe. a washing-bottle charged with a solution palladium chlorid, in order to indicate the passage of the carbon monoxid and the speed of the combustion.
  • the IUSOI'UOH of a long connecting pipe /L for returning the gas current. is avoided by con net-ting together the calcium chlorid pipe c i and the soda-lime pipe (Z by means 0% a U-pipe '2' and arranging them one behind the other.
  • the outlet pipe j of the soda-lime pipe 1/ enters into the rear end of the jacket pipe 71, so that the reversing of the gas current is produced without inserting a separate pipe.
  • the absorption tubes 2, ffllnd the washing-bottle y are in this case, 'ef course connected to the 't'ront end pipe 7).
  • the v scribed is made up of two concentric tubes forming two combustion tubes onfurnaces and that an absorption apparatus is pro vidcd for the gaseous products'ot comlmstion from each tube.
  • the umibsorbed gases from the first absorption apparatus being subsequently passed through the second combustion lube and then throughthe second absorption apparatus.
  • the gases a re thus twice subjected to combustion conditions so that thorough combustion is secured. while the absirrbable products of combustion are ab scrbcd after each such combustion.
  • An apparatus of the nature described comprising an inner main combustion tube, an absorption apparatus for the gases escapin; therefrom. an outer combuslion tube surrounding said inner tube with a tight. joint of the jacket apparatus deapparatus arm said las t menti nged to feceive the i2. oned combustion tu ses from HUGO BEACH;
