An antenna housing is disposed on the mounting plate and has a rod-shaped antenna mount within the opening and below a recess.

Abstract: Interfering double images that occur with curved windshields made from laminated glass during night driving in transmission and with head-up displays in reflection can be reduced by a wedge-shaped thermoplastic intermediate film. The wedge-angle profile required for compensation of double images is determined locally as a function of pane shape and installation situation. If the vehicle has a head-up display system, the wedge-angle progression can be determined in the HUD field such that double images are prevented there in reflection. However, outside the HUD field, a wedge-angle progression that compensates double images in transmission is selected. The specifically adapted wedge-angle profile enables better compensation of double images than is possible with a film with a constant wedge angle.

Abstract: In a laminated glass sheet with a fixing device introduced into a through-hole for objects, particularly for antennas, the through-hole is made up of holes of different sizes in two rigid sheets of the lamination, and the fixing device includes at least two parts introduced into the through-hole, pressing against surfaces around the edge of the through-hole, which surfaces are situated one facing the other. The two parts of the fixing device press from both sides against the surfaces around the edge surrounding the smaller hole made in the sheet, in that region of the walls of a smaller hole that exhibits an edge compression stress that is increased by heat treatment by comparison with the remainder of the surface of the sheet.

Abstract: A process and system for bending glass sheets heated to their softening point. The glass sheets are laid on a concave bending frame and prebent by gravity. The prebent glass sheets are transferred to a transfer former with a concave forming surface, the transfer former being moved up through the concave bending frame, the perimeter of which is larger, and thus picking up the glass sheets. The transfer former is positioned so that in vertical projection it overlies a final bending former in the form of a frame with a concave forming surface. The transfer former is moved up through the larger-diameter final bending former, the glass sheets being laid on the final bending former. The glass sheets are bent into their final shape, and at the end of the bending operation, the glass sheets in their final shape are transferred from the final bending former to a transport system and cooled.

Abstract: 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.

Abstract: An electrode is produced on a rigid or flexible support substrate, including a grid network of very fine electrically-conductive lines with nodes and links, to produce a diffraction pattern, as much as possible in an arc shape, in the light transmitted and that results in an absence of high-level optical impacts. The grid network may in addition be produced without preferential direction with a number of three lines joining up at each node and/or with conductive sections extending in the shape of an arc or in wave form between the nodes.
