Definitions
- the void detector comprises a pneumatic sensor and associated pressure switch and relay elements to provide readout and to stop the dryer motor drive upon detection of a void.
- Moisture is monitored by a continuous electrical conductivity measuring apparatus comprising a grounded feeler riding above and against the tow and a conducting guide below the tow which is attached to electrical circuitry ar ranged not only to count and alarm when moisture in the tow exceeds certain predetermined limits but also to provide a measure of length of such moisture spots in the tow.
- the grounded feelcr also serves as a part of a detector of tow mechanical defects by being mounted to the input shaft of a pneumatic position transmitter which in turn is arranged to stop the tow moving means when actuated by movement of the feeler as a knot or similar defects passes under the fecler.

Abstract
AN APPARATUS COMBINING VOID DETECTION AT THE ENTRANCE AND MOISTURE DETECTION AT THE EXIT OF A TOW DRYER. THE VOID DETECTOR COMPRISES A PNEUMATIC SENSOR AND ASSOCIATED PRESSURE SWITCH AND RELAY ELEMENTS TO PROVIDE READOUT AND TO STOP THE DRYER MOTOR DRIVE UPON DETECTION OF A VOID. MOISTURE IS MONITORED BY A CONTINUOUS ELECTRICAL CONDUCTIVITY MEASURING APPARATUS COMPRISING A GROUNDED FEELER RIDING ABOVE AND AGAINST THE TOW AND A CONDUCTING GUIDE BELOW THE TOW WHICH IS ATTACHED TO ELECTRICAL CIRCUITRY ARRANGED NOT ONLY TO COUNT AND ALARM WHEN MOISTURE IN THE TOW EXCEEDS CERTAIN PREDETERMINED LIMITS BUT ALSO TO PROVIDE A MEASURE OF LENGTH OF SUCH MOISTURE SPOTS IN THE TOW. THE GROUNDED FEELER ALSO SERVES AS A PART OF A DETECTOR OF TOW MECHANICAL DEFECTS BY BEING MOUNTED TO THE INPUT SHAFT OF A PNEUMATIC POSITION TRANSMITTER WHICH IN TURN IS ARRANGED TO STOP THE TOW MOVING MEANS WHEN ACTUATED BY MOVEMENT OF THE FEELER AS A KNOT OR SIMILAR DEFECTS PASSES UNDER THE FEELER.
