Abstract

1520975 Measuring moisture electrically SAINT-GOBAIN INDUSTRIES 28 May 1976 [2 June 1975] 222291/76 Heading G1N (A) [Also in Division H5] A window pane with heating elements deposited thereon includes a moisture detector Fig. 3 comprising a pair of adjacent electrodes 11, 12, and a terminal 10 mounted on a conductive layer 14 on the pane surface, the whole of the detector including the terminal being within the area of the pane which is freed of moisture by the heating elements. The electrodes are interdigitated and the collector for electrode 12 is formed by the upper heating element 4. A conductor 17 screens the detector from leakage currents and an upstanding portion 18 channels away any water droplets running down the pane. When the size of the area demisted is limited by the available power supply the detector may be situated in an auxiliary area 27 formed by a localised diversion of an element 22. This avoids long connections to the detector passing across the window. In a further embodiment Fig. 5 (not shown) the detector is formed between two elements (19, 20) at the side of the pane, the said elements forming collectors for one of the electrodes (12). Reference has been directed by the Comptroller to Specification 1458092.
