<p>Advantages: assures continuous monitoring of the contents thus allowing assay of the composition by simple means. Consists of a winch drum of special design which narrows from one extremity to the other and whereby the traction assembly which carries the probe is connected to one of the extremities at which the radius is smallest. The narrowing of the drum envelope corresponds to the increase in weight developed by the rotary torque resulting from the unwinding of the traction assembly holding the probe.</p> |
