<p>1,109,490. Moisture-sensitive resistors. AUTEL S. r. 1. June 22, 1966 [Nov. 8, 1965], No. 27840/66. Heading G1N. A transducer sensitive to deposited moisture comprises a parallel pair winding of enamelled wire, from which the enamel is removed on the outer surface leaving the conductors separated by short distances in which moisture is deposited to produce contact between them. The winding may be formed with round or square conductors, or comprise two interleaved comb-shaped conductors. One conductor or a separate winding may be used, as a local heater to adjust the threshold point. As described, one winding is connected to a D. C. source, and a voltage appearing on the other winding when moisture is deposited, may be used to operate a fan or windshield wiper.</p> |
