Abstract

645,998. Determining physical qualities of materials. SQUARE GRIP REINFORCEMENT CO. (LONDON), Ltd., and GLEGG, G. L. July 28, 1948, No. 19109/49. Divided out of 645,975. [Class 37] [Also in Group II]. Apparatus for determining the water content of fluid concrete comprises means for agitating the mixture until the heavier constituents have sunk to the bottom, and means for measuring the maximum current between two spaced electrodes in the upper part of the mixture when a known E.M.F. is applied. The agitating device may consist of a motor 5, Fig. 2, driving an eccentrically-mounted weight 7, or a vibrator, Fig. 3, consisting of an iron armature 23 swinging between two coils 30, 31 alternately energized through contacts 28 and 26 or 27. A change-over switch 16 connects either a fixed resistance 14 or the electrodes 2, 3 to the battery 11, the applied voltage being adjusted by a potentiometer 13. Specification 588,607, [Group II], is referred to.
