Title: Insulating glazing has two panes one composed itself of two sheets - prefabricated with sensitive sun filtering coating enclosed between them
Inventor: BAYER FRANZ
IPC: E06B3/67
Filed: 1980-06-02
Abstract: An insulating glass pane or glazing unit comprises two panes with the conventional insulating space between them, one of these panes being itself composed of two panes with a small gap between them. The face of one of these last two panes which faces towards this narrow space is coated with a vapour-deposited or similar layer of slightly tinting, filtering or other material which still leaves the window transparent. This arrangement enables the very sensitive vapour-deposited coating to be applied onto a sheet of glass, to be then immediately covered by the second sheet of glass forming the double unit with the small space between them, so that henceforth the vapour-deposited coating is protected. This prefabricated unit, which can only be producedin a works comprising a coating plant, is then robust enough to be transported and used by other double glasing manufacturers for assembly together with the further pane to constitute double glazing units.

Title: Compressed foamable PVC film prodn. for making relief - using inhibitor or initiator, by calendering premix contg. lubricant below foaming temp.
Inventor: GUYER HANS DIPL ING
IPC: C08J9/00
Filed: 1980-09-27
Abstract: Prodn. of slightly compressed foamable PVC films, which can be inhibited and activated and contain an undecomposed blowing agent, is carried out by calendering. A PVC of the suspension and/or emulsion type is used and the shear force during premixing is reduced by adding a lubricant. Mixing is carried out only until the mixt. gels and the gel is rolled out on a 2- and multi-calender below the decomposition temp. of the blowing agent. Suspension PVC with a K value below 75 or a mixt. of suspension and emulsion PVC, both with a K value below 75, is used. An internal and external lubricant, esp. hydroxystearic acid, is added. The pH of the PVC is shifted towards neutral by adding a buffer. Premixing is carried out at 110-150 -eg.C and calendering at a lower temp. The film is useful for making prods. with a structurised surface by after-treatment with inhibitor or initiator as required. This makes the prodn. of relief surfaces cheaper and allows a high degree of recycling of scrap.
