Abstract

1,205,227. Automatic titration. CHEMIEFASER LENZING A.G. 5 Dec., 1967 [16 Dec., 1966], No. 55335/67. Heading B1X. automatically determines the ratio of the pump strokes, for a variable feed rate pump, or the ratio of the feed periods, by means of timer 10, for a constant feed rate pump. The ratio is recorded at 11. M 1 M 2 may be magnetic valves controlled by means 9. There is reference to use of the apparatus of Fig. 2 (not shown) which has pipes for feeding three liquids to common feed device (6), in a reverse redox titration for determining free chlorine using iron sulphate and permanganate. In periodic automatic titration of aqueous solutions, the liquid to be analysed and the titrating liquid are supplied successively by means of variable or constant feed rate pump 4 through common feeding device 6 into reaction vessel 1 until means 2 indicates the titration endpoint, when programming means 9
