Abstract: 946,688. Spectral analysis apparatus. TECHNICON INSTRUMENTS CORPORATION. Oct. 13, 1960 [Nov. 10, 1959], No. 35056/60. Heading G2J. A method of spectral-flame examination of a test or sample liquid in respect to an ingredient thereof according to which the liquid is introduced into the flame through a tubular passage is characterized in that the liquid is first dialyzed to remove substances which, if present, might interfere with the examination of the liquid or with the operation of the spectral-flame burner, said ingredient of said liquid or a proportional quantity of said ingredient being diffused by the dialysis in a recipient liquid which is thereafter introduced into the flame of the burner instead of the direct introduction of the test or sample liquid into the flame. The apparatus shown for carrying out this method comprises a pump 12 having a platen 68 and resilient tubes 30, 34, 32, 44, 48 and 66 which are simultaneously and progressively compressed along their lengths by rollers 70, which are conveyed by chains 72 driven by a motor-actuated shaft 73. Through the tube 30 is fed a sample of blood serum, and a reference liquid (for example, a lithium nitrate solution) is fed through the tube 32. Through the tube 34 is fed air or another inert fluid. The three tubes are joined at 36 so that a segmented fluid stream is passed through tube 38 and mixing coil 40 to one side of the membrane 42 in a dialyzer 14 which is preferably as described in Specification 827, 924. To the other side of this membrane is fed through a tube 52, a segmented stream of distilled water and air respectively supplied to tube 52 by tubes 44, 48. The dialyzer and the mixing coils 40 are in a temperature controlled bath 47 and the blood serum is dialyzed to remove any protein that may be present. The serum and reference liquid which diffuse through the membrane 42 and mix with the distilled water then passes through a tube 18 to a T-junction 16, where the air is drawn off through a pipe 64 to the tube 66. From the T-junction 16 the serum and reference liquid then pass up the tube 26 of a spectral-flame burner 20 forming part of a spectroscopic analyser including a recorder 24. Specification 946, 689 also is referred to.

Title: A process for the fractional condensation and/or distillation of hydrocarbon oils
IPC: B01D3/14
Filed: 1935-12-31
Abstract: <PICT:0467617/III/1> Hydrocarbon oils are fractionally distilled by passing the vaporized oil into a primary fractionating column, withdrawing in liquid form one or more fractions formed at different levels between the top and bottom of the column into a secondary distillation column in which the fraction is freed from unwanted lowest boiling constituents by being heated outside the column and returning the constituents removed to the primary column at substantially the same level at which the fraction was withdrawn. The secondary columns may be situated within the primary column. A fraction collecting on a plate in the main column 1 is withdrawn through a line 3 to the secondary column 2 where low boiling-point constituents are removed by directing the reflux collecting on the bottom plate through a pipe 11 to the left compartment formed by a plate 16 in the bottom of the column and circulating the liquid through a line 6 back into a tray in the right - hand compartment, the liquid being heated while passing through the pipe 6 by means of a heat-exchanger.  Part of the distillate drawn off at the top of the column may be condensed in a condenser 14 and returned to the column as reflux, the remainder passing through the line 4 back to the column 1.
