<p>1,001,885. Automatic sampling and mixing for analysis. A. AUSCHERLIK. April 24, 1962 [Sept. 4, 1961], No. 15455/62. Headings B1C and B1X. A first siphon 1 is primed by means of a pressure impulse (from line 10) to release a liquid sample into a first mixing zone 3, the release of said sample priming a second siphon 2 whereby a first treating liquid is released into said mixing zone, and, if desired after the addition of a second treating liquid from a third siphon 4 to form a mixture in a second mixing zone 5, releasing the mixture (by applying a pressure pulse through 11 or 11<SP>1</SP>) and making a required test thereon (in chamber 6), the tested liquid being finally passed through a constriction 8 to cause a further pressure impulse (through line 10) to release a second sample. The numerals refer to the embodiment shown in Fig. 1 wherein the various pieces of the apparatus are formed in blocks, e.g. as shown in Fig. 2, in which wells and grooves are cut in portion 13, and 14 is a closure plate. The release of the liquids from mixing zones 3 and 5 and measuring chamber 6 may be by means of suitably programmed impulses applied to 11, 11<SP>1</SP> and 12.</p> |
