摘要:
The invention relates to a transparent pane with a transparent heatable coating, which extends at least over a part of the pane surface, in particular over its visual field. The heatable coating is divided by at least one heatable coating-free zone into at least one first heatable coating zone and a second heatable coating zone, wherein the two heatable coating zones are in each case electrically connected to at least two collecting conductors such that after application of a supply voltage that is provided by a voltage source, in each case a current flows over at least one first heating field formed by the first heatable coating zone and at least one second heating field formed by the second heatable coating zone. At least one heating element is disposed in the heatable coating-free zone, which heating element has an ohmic resistance such that by means of application of the supply voltage to the heating element, the pane is heatable in a surface area containing the heatable coating-free zone. The at least one heating element is configured such that by means of application of the supply voltage to the heating element, the pane is also heatable in at least one surface area adjacent the coating-free zone which surface area contains at least one of the collecting conductors.

A method and device for bending superposed sheets of glass. The sheets are picked up by a top form furnished with a suction creating an upward airflow blowing over the rim of the sheets, the suction being sufficient to lift and hold the superposed sheets against the top form, then the sheets are pressed between the top form and a full surface solid concave bottom form furnished with openings, the pressing beginning conducted while the suction is not yet finished or is finishing, then the superposed sheets are formed, by suction of the main face of the bottom sheet through the openings of the bottom concave mold, the forming by suction beginning while the pressing is not yet finished, and then the sheets are cooled. Windshields free of optical defects may thus be produced.

A carrier, in particular a plastic film, comprising an electrical heating layer is described. The heating layer is applied to at least a portion of a carrier surface. The heating layer is electrically divided by one or more first separating zones, each of which is designed such that a current path changes the direction of flow thereof at the free zone ends, and one or more second separating zones, which are designed such that the current path changing the direction of flow thereof at the free zone ends is divided in at least some sections into a plurality of electrically parallel current sub-paths. One or more second separating zones are associated with at least one free zone end of a first separating zone, with the second separating zones arranged in an aligned extension to the first separating zone.

An arrangement and a method for de-icing a transparent window, in particular a vehicle windshield, with an electric heating device, are described. The method has the following steps: Step A): Measuring a window temperature before an initial application of a heating voltage; Step B): Measuring the window temperature after a beginning of a heating period; and Step C): Applying a heating voltage of more than 100 volts to a heating device over a heating period of a maximum of 2 minutes, in particular a maximum of 90 seconds, and repeating step B).

A transparent window (1) has an electrically heatable coating, which extends over a substantial part of the area of the window (1), in particular over its viewing area (A). In addition, the coating is electrically connected to at least two mutually opposite low-impedance bus bars in such a way that, after an electrical feed voltage has been applied to the bus bars, a current flows between them over a heating area (21) formed by the coating. In this arrangement, there is between the bus bars and the heating area (21) at least one at least partially light-transmitting transitional region (15), the effective surface resistance of which is lower than the surface resistance of the coating. In order to obtain a transitional region (15) having the visual appearance of a band filter, it is proposed that the surface resistance in the at least one transitional region (15) increases in the direction from the assigned bus bar to the heating area (21).

A transparent windowpane including a resistive heating coating that extends over a substantial part of a surface of the windowpane, and over a main field of view, and which is electrically connected, at least indirectly, with at least two busbars such that, when a power supply voltage is applied between the two busbars, a current flows between the busbars, heating a heating field in the heating coating. The heating field includes at least one semiresistive region in direct contact with at least one busbar, and including conducting strands in a form of thin longitudinal wires, the ohmic resistance of which is less than that of the heating coating. At least one conducting strand has a transverse conducting structure in electrical contact with the semiresistive region.
