  • Patent number: 5755845
    Abstract: The invention relates to the press bending and tempering of glass sheets, especially for use as glazings in vehicles. When the press bending system is not located in a heated environment such as a furnace, it is important to maintain the glass sheets at a sufficiently high temperature for an adequate degree of temper to be achieved on quenching the sheet. The present invention provides a method of bending and tempering a thin glass sheet comprising pressing the substantially horizontal sheet between moulds having opposed complementary shaping surfaces, at least one of the surfaces being heated, and subsequently quenching the surfaces of the sheet characterised in that the heated shaping surface is maintained at a temperature in the range from 200.degree. C. to 350.degree. C.

  • Patent number: 5735922
    Abstract: Glass sheets are press bent and tempered, especially for use as glazings in vehicles. Such glazings are required to be accurately bent to a complex shape while meeting high standards of optical quality and fracture safety at an acceptable cost. A method of bending and tempering a glass sheet is provided comprising heating the sheet in a furnace, including heating at least one portion of the sheet to a higher temperature than another portion, conveying the sheet out of the furnace and into a press bending station, shaping the sheet by pressing it between opposed complementary upper and lower press members, at least one of the members being internally heated, transferring the bent glass sheet onto a shuttle carrier ring conforming to the periphery of the sheet, and tempering the sheet while supported on the carrier ring. A corresponding apparatus is also described.

  • Patent number: 5672189
    Abstract: Press-bending station for bending sheets of glass during the course of automated production of identical motor vehicle windows within specified batch sizes, where the glass sheets to be bent are heated in a continuous furnace to a specified bending temperature and directly after leaving the continuous furnace are fed in horizontal position with the aid of a horizontal conveyor into the press-bending station. It incorporates a male press mold and a female press mold. The male press mold is a cast full mold and consists of an aluminum alloy. The male press mold possesses heating passages for fluid heating with the aid of a liquid heat transfer medium and can be heated with sufficiently homogeneous temperature distribution to a thermal expansion temperature which is below the bending temperature. The temperature of the male press mold can be controlled and/or regulated by means of the liquid heat transfer medium.

  • Patent number: 5599367
    Abstract: Process for operation of a press-bending station for bending glass sheets during the course of automated production of motor vehicle windows, during which manufacture the glass sheets to be bent are fed into a cyclically operating press-bending station, and after the bending operation are fed out of the press-bending station with the aid of a means of conveyance in the form of a shuttle ring into a cooling and/or toughening station. The press-bending station incorporates in its press an upper male press mold with vacuum-locating device for the bent glass sheet, a lower female press mold and the shuttle ring. The press incorporates a press upper beam which is movable up and down, to which a male press mold is attached. The bent glass sheet retained under the male press mold with the aid of the vacuum-locating device is fed to the shuttle ring by a downward movement.

  • Patent number: 5288558
    Abstract: An attachment for a video screen of a cathode ray tube of a monitor or TV receiver is constituted by a glass pane having on a front side, facing away from the video screen, a multilayer anti-reflective coating. If necessary, the glass pane on a rear side, facing towards the video screen, may incorporate an absorptive coating. The anti-reflective coating is limited to two active dereflective layers. One of said two layers is a metal layer of gold or a metal alloy with a gold content of more than 50% and with a thickness of 4 to 10 nm. The second active dereflective layer is of dielectric material with a refractive power of n<1.8 and constituting an interference layer which faces away from the glass pane and which is essentially absorption-free and forms an anti-reflective layer for the visible region of the spectrum.
