<p>In the automatic coating and colouring of medicament units with liquid materials the degree of moisture in the coating vessel is automatically regulated by an electric moisture regulator as in parent patent. This is modified by using an impulse-interval-relay between lower value contact and moistening device and/or a delayed-action relay between upper value contact and the demoistening device. The relative moisture in the coating vessel is conducted to the sensing element by an air-current just adequate to prevent extraneous air to be measured as well. This prevents the coating operation from being endangered by the usual tendency of moisture regulators to "overstep".</p> |
