  • Patent number: 7232497
    Abstract: A fire-resisting composite glass is comprised of at least two glass plates (1, 2) and an interspaced cavity (6). The distance between the glass plates (1, 2) is determined by an encompassing bead (3) of plastic spacer material. In addition, in the margin region between the glass plates (1, 2) a bead (4) of sealing material is introduced. With the aid of at least one core element an opening is formed in the bead (3) of spacer material for filling the cavity (6). After the filling, this opening is closed with an entrainer stopper and simultaneously the cavity (6) is vented. During the closing the plastic spacer material (3) is joined again in the region of the opening and subsequently the entrainer stopper is covered with sealing material (4). The method and the device for carrying out the method permits the automatic application of encompassing beads (3, 4) of spacer material or of sealing material as well as the sealing and protection of the margin regions before the cavity (6) is filled.

  • Patent number: 7008492
    Abstract: A method for the dimensionally accurate application of an elastoplastic spacer strip onto a glass pane intended for producing an insulating glass unit is that the spacer strip is not withdrawn from the storage drum but instead it is unwound in a manner free from any tensile stress and that the same is kept free from tensile and shearing stresses on the further route up to the pressing onto the glass pane, this being despite the fact that the application speed will inevitably fluctuate several times between zero, and a maximum value while edges of the glass pane are covered mechanically. The apparatus for performing the method therefore comprises a compensating or tailback section (3) between a first adjustably driven pair of rollers (1) and a second adjustably driven pair of rollers (9) as well as a sensor for recognizing the position of the strip in the compensating section.

    Abstract: To reduce the size of an optical unit having a polarizing device and an integrator lens, to cut costs, and to reduce the size of the entire device light from a lamp is incident on a lens group on the light incidence side of an integrator lens, the polarizing device is located between a lens group on the light incidence side and a lens group on the light exit side of the integrator lens. The light incident on the polarizing device is subjected to polarization separation. The polarized light emerging from the lens group on the light exit side is converted into parallel light via a shutter and a second planar mirror by means of a collimator and is emitted onto a workpiece. Since the polarizing device is located between the lens group on the light incidence side and the lens group on the light exit side, the length of the optical path can be reduced. Furthermore, the diameter of the polarizing device is prevented from becoming large. Thus, the size of the device can be reduced.
