Title: Improvements in or relating to arrangements for the hydromechanical generation of pneumatic impulses
IPC: B01L99/00
Filed: 1965-04-15
Abstract: 1,064,341. Sampling system for analysis. C.K.D. DUKLA, NARODNI PODNIK. April 15, 1965 [May 16, 1964; Sept. 19, 1964], No. 16241/65. Heading B1X. [Also in Division B8] A pneumatic impulse generator for use in sampling and dispensing liquids in photometric analyzers comprises a displacement device 1 in a storage vessel 2 having an outlet pipe with a restriction 4 and an overflow pipe 38 and a liquid supply tube 6 adapted to be moved by means 39 so as to discharge the supplied liquid alternately into the storage vessel or into a discharge funnel 7. The device 1 is open at its bottom and connected at its top by a tube 37 which communicates via branch tubes 34 35, 36 to the top of dispensing pipettes 31, 32, 33 the pipette 31 being maintained filled as shown from a tank 41 filled via the supply tube 6 and the funnel 7 and pipe 40; in this embodiment, the liquid in the pipette 31 is the sample liquid and the liquids in the pipettes 32, 33 are reagents. In operation, when it is desired to feed the three liquids into a common collecting tube 51, the supply tube 6 is moved by means of an electro magnet 39 so as to bring the tube above the vessel 2. The sample liquid then flows into the vessel until it overflows through the outlet 38. During the rising of the liquid in the device 1 the air pressure developed therein causes the liquid in the pipettes to be dispensed. The tube 6 is then returned to above the funnel and the liquid in the vessel 2 drains away at a speed determined by the restriction 4. In a further embodiment, Fig. 4 (not shown) a second vessel 11 is located above the vessel 2 and has connected thereto a pipette 18. The vessel 2 contains a displacement device 10 which is connected via a pipe 17 to a siphon tube 13 connected to the vessel 11; a further displacement device 9 is connected by a pipe 24 with the pipette 18, the pipe opening into a funnel 27. In operation, with the supply tube 6 above a funnel 26 liqiud flows into the vessel 11 and then, via an overflow pipe 12, into the vessel 2. The tube is then moved over the funnel 27 so that the liquid rises therein to close the open end of the pipe 24. As the liquid in the vessel 2 drains away, a suction is developed in the pipe 24 thereby drawing liquid into the pipette 18; when the level of the liquid in the vessel 2 drops below the device 9 the suction is broken and the liquid in the pipette is emptied into the vessel 11. As the level drops still further a suction in the pipe 17 is developed thereby causing the liquid in the vessel 11 to siphon away through pipes 13, 15.

Title: Method for extracting substances from divided solid material and apparatus for the carrying out of said method
IPC: B01D11/02
Filed: 1948-06-22
Abstract: 670,697. Extracting sugar &c. RAFFINERIE TIRLEMONTOISE SOC. ANON. June 22, 1948 [Aug. 23, 1947], No. 16778/48. Classes 81 (i) and 127. In a method of continuously extracting substances from divided solid material, the liquid and solid material are moved in counter-current wherein the liquid is circulated in at least two streams which are brought periodically and successively into contact with the solid material. In an example an apparatus for carrying out the process applied to the extraction of sugar from beet comprises a rotatable cylindrical drum 101 having two interthreaded helical bands 103, 104 fastened on the inner surface 102 which define in the bottom of the drum two series of cells 106 to 109 and 110 to 112 each filled with diffusion juice to a level 105. On one complete rotation of the drum the liquid in cell 106 will be in 107 and that of 110 will be in 111 and so on and thus the liquid circulates in two streams acting in parallel and passing the cells of each series successively. The cossettes are introduced through two entrances provided at one end of the double thread screw and in order to make them soak successively in the several fractions of liquid travelling within the drum the windings of both helical bands are united by axially extending openwork grids 113 which draw the cossettes out of the liquid, strain them during their travelling upwardly (see Fig. 6). The grids are united by a longitudinal solid plate 114 carrying slanting slides 115 forming passages such as 116 for making the cossettes, lifted into the upper half of the drum, drop across the helical bands 103, 104 e.g. from cell 109 the cossettes are lifted and slide in a passage 116 whereby they will be laterally off-set along two cells and discharged into the liquid of cell 108 which occurs in the first half rotation. During the next half rotation the cossettes are moved with the sugar juice where they are lying and pass into the cell 112. Thus after a complete rotation the liquid will be advanced two cells in the direction of the arrow 118 while the cossettes are advanced along one cell in the opposite direction.
