Abstract
Abstract Improvement for a device for the rapid measuring of the degree of humidity of substances comprising a diffuser intended for passing hot air produced in a stove or an oven through these substances, the said substances being contained in a cup, whose bottom is permeable to air and in which the desiccating of the substances under the action of the passing of the hot air is effected. The diffuser used is characterized in that it is constituted by a nozzle comprising a first diaphragm arranged on the same side as the oven and a second diaphragm arranged on the same side as the cup.

Improvement in a device for the rapid measurement of the degree of humidity of substances comprising a diffuser intended for passing hot air produced in an oven through these substances, the said substances being contained in a cup whose bottom is permeable to air and in which the desiccation of the substances is effected under the effect of the passing of the hot air, the improvement consisting in a diffuser consisting of a cylindrical nozzle of circular cross section comprising a first diaphragm arranged on the same side as a stove having a flat ring concentric with said nozzle and having a circular hole in its central portion, a second diaphragm arranged on the same side as the cup constituted by a circular plate drilled at its periphery with the nozzle, with a series of holes arranged substantially at right-angles to the ring of the first diaphragm.
