摘要

A device ensuring the immobilisation, in predetermined position, and the indication of the position of the wheel of a dissolver, characterised in that it consists of a locking and position-indicating finger 1 whose axial movement is controlled by means of a mechanical driving device external to the cell containing the dissolver and of a series of imprints integrally attached to the said wheel having variable depths. <IMAGE>
