Abstract: The glass sheets (2) of an asymmetric glass-sheet pair, which is intended for the production of laminated glass, are preheated in a preheating furnace (1) and then undergo a press-bending process in a press-bending station (4). By means of a temperature measuring point (11) arranged at the exit of the press-bending station, it is ensured that the glass sheets exhibit a uniform bending behaviour, in order to guarantee identical restoring forces during cooling. The temperature measuring point (11) is connected to a control device (16), which causes an intermediate cooling of the glass sheet heating more rapidly by means of an intermediate cooling installation (12, 13) in the pre-heating furnace and/or lengthens its dwell time in the press-bending station (4) by means of a timing control element (15).

Abstract: A motor vehicle antenna pane with improved diversity and/or multiband applicability in the VHF range for mounting in a metal surround (1) provided with a conductive panel (2) spaced from the metal surround (1) such that an elongated dielectric slot (3) is produced between the two. In the slot (3) are arranged a number of slot antennas incorporating elongated radiating areas (4,5) extending along the length of the slot (3) the geometric forms of which are bounded by an HF-conductive frame incorporating at least one ground edge conductor (1,6, 7) and one signal edge conductor (2, 8, 9) and at least one terminating conductor (10, 11) terminating the slot antennas at their longitudinal ends.

Abstract: This invention concerns a process for producing a curved, laminated safety glass sheet from a first curved glass sheet (1), a first laminated layer (2), a thermoplastic substrate sheet (4) with a biaxially drawn thin-layer system (3), a second laminated layer (5), and a second curved glass sheet (10) conforming to the first one.
