    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.

    Fig. 1 shows a glass provided with an electrical heating device with a control element and a switching element; FIG. 2 shows the execution of the control; in fig. 3 - the same, option; in fig. 4 - the same; in fig. 5 - control located between two electrically heated elements; FIG. 6 shows devices on glass of large j size; in fig. 7 shows the control element of the variant of the device according to FIG. 6. Glass 1 for vehicle in FIG. 1 is equipped with a network of 2 horizontal electric heating elements, connecting two tires 3.1 and 3.2. This. the network is preferably made of an electrically conductive frit superimposed on a silk screen, which is fired by glass firing, and then strengthened and protected by electroforming. It covers most of the glass 1 and the external electroheating elements 4.1 and 4.2 are located at a rather insignificant distance from the corresponding edges 5.1 and 5.2 of the glass 1. The section of the glass that is cleaned from fogging is located in this case between the lines A. The control is located on the axis of symmetry of glass 1 in position 6.1 above the upper electric heating element 4.1. There can be several controls, for example, placed in position 6.2 below the lower electric heating element and in positions 7.1 and 7.2 along tires 3.1 and 3.2. The switching element 8 is connected to the battery and connected via capacitor 9 to the connecting bus 10 in such a way that the signal transmitted by the control opens or closes the contact b of the heating control via relay 8 depending on whether the inner surface of the glass. FIG. 2 shows the internal structure of the control used in 6.1. Of FIG. 1. This control is about 15 meters tall and includes two electrodes 11 and 12 having the form of successive crests, the first one having vertical teeth that are not joined. mediocre with the electric heating element 4.1 and including its section q, the second has vertical teeth connected by means of the upper collector 13c with a surface 14, which serves to secure the connecting bus 1O. This surface 14 is located under the collector 13. Thus, the section 15. of the active zone, the furthest from the electric heating element 4.1, is negative from the outer edge of the control body, the most remote from this electric heating element, only the thickness of the collector 13, i.e. several tens of 9 24 millimeters. From this it follows that the moisture precipitation boundary formed by line G is approximately one millimeter from the control, so that between it and the mass formed by the frame of the machine, a resistance zone 15.2 is created between the upper edge 5.1 of the glass 1 1, which exceeds the internal resistance of the organ control until heating ceases. The electric heating element also has a secondary conductive surface 16 in the central part of the control body, which serves to facilitate electroforming: the galvanoplastic electrode connected to the conductive surface 14 also contacts the secondary surface 16, which makes it possible to reinforce the metallic deposit on the lower ridge teeth. If this precaution is neglected, the electroforming current density in the corresponding zone tends to decrease as a result of the relatively large surface of the printing network at the location of the control body. In the embodiment shown in FIG. 3, the control is similar, but the two conductive surfaces 14 and 16 are located one above the other, which makes it possible to reduce the width of the control without a significant increase in its height. In addition, the electrode 11 connected to the connecting bus 10 is completely surrounded by conductor 17, which is part of electrode 12. This conductor is a shield that isolates the electrode 11 from the mass formed by the frame of the machine along the edge of the glass. Since the electrode 11 is disconnected by means of the capacitor 9, no significant direct voltage can occur in the inside of the control; external leakage current remains very weak if the sensitivity of the control is sufficiently adjusted. Conductor 17 also removes moisture droplets from the core section 15.1, which may occur as a result of condensation, but a groove 18 may be installed on top of it. The teeth of electrode 11 end a few millimeters from the electroheating element 4.1, except for two extreme teeth, which run a few tenths of a millimeter closer to element 4.1. The control shown in FIG. 4, is similar to that described, but polo5,. 9, the tire 10 is reversed, and the collector 1 is also located along the electric heating element 4.1 in several tenths of a millimeter. FIG. Figure 5 shows the internal structure of the control located on the side between two electric heating elements, for example at position 7.2, on one of the sides of the glass 1. The ridge formed by electrode 12 connected to bus 3.2 is double and includes a series of vertical lines. teeth, some of which are connected to the upper electromotive element 19, and others to the lower electric heating element 20. The auxiliary electrode 11 is formed by teeth connected through the middle collector 1 to the conductive surface 14, constant for compounds with connective bus 1D. An additional conductive surface is formed by a collector 13. Heating stops when the area released by the oV of the settled steam reaches the line largely corresponding to the D line. In this case, the control is fully located in the dry zone and, in addition, is surrounded on three sides conductors that are located in the potential of the electrode 12. The shielding conductor 17 can be located with the fourth CTOpotoi sensor, however this. does not give much results. FIG. 6 shows a glass 21 having a greater height, the upper electrically heating element 22 of which is at a considerable distance from the upper edge 23 of the glass; this distance can reach 2 mm and even more. The middle part 24 of the electric heating element 22 is located near the upper edge 23 of the glass 21, in the central zone at a distance which can reach ten centimeters, and in its middle part it is divided into two branches 24.1 and 24.2, inside of which the control body is located. The latter is shown in FIG. 7 and has a form similar to that shown in FIG. 5. Both branches 24 of the electric heating element 22 are connected by two auxiliary surfaces 25. 1 and 25.2, forming a second visibility zone 26. They have a rounded shape, which in the upper part of the governing body facilitates the flow of water along the sides outside the core 27. The additional electrode has similar structure. It is connected to the wire - 02 neck surface 28, which serves to fasten the connector 29. The device operates as follows. When the heating is turned off, the thermal zones around all the electric heating elements are connected in series and the glass-cleaned area is located between the pin fr, the distance from which to the upper electric heating element 4., n to the lower electric heating element 4.2 can reach, depending on atmospheric conditions 25 mm. The heating is turned off at the moment when the upper boundary of the mist-free area gradually rises from the upper electric heating element 4.1 as the heating proceeds, sufficiently clears the active zone formed by the electrodes, the control element, having reached, for example, two lines B, the distance between which depends on the shape of the control and adjustment device. The proposed device improves the efficiency of glass cleaning by improving the uniformity of heating, and also reduces energy consumption by eliminating parasitic currents, t Formula 1. Glass for a vehicle equipped with an electric heating device according to hfe 5O6282, characterized in that cleaning glass by improving the uniformity of heating while reducing energy consumption by eliminating parasitic currents; all elements of the control body are placed between the electric heating element and the boundary of the glass surface to be cleaned, and the control electrode connected with the conductive element is connected to the electric heating element in the area of the latter.
