摘要:
Laminated, transparent set of panes made of brittle materials and interleaved laminated films, wherein the brittle materials are various glasses, special glasses, glass-ceramics, transparent ceramics and crystalline materials, process for producing and bending the set of panes and films, and its use thereof, as a bulletproof, unbreakable and shockproof glazing with a low weight per unit area.
摘要:
The device for blank pressing glass bodies includes a first rotary indexing table with preforms for forming parisons from glass gobs; a second rotary indexing table having pressing molds and pressing tools for pressing the parisons into final form after formation in the preforms; and a device for shifting the first rotary indexing table relative to the second rotary indexing table so that each preform is positionable in a transfer position between a pressing tool and a pressing mold. Each preform is mounted on the first rotary indexing table by a indexable mount for holding it in a first horizontal position or in a second position pivoted away from the first position, so that, when a preform is in the transfer position, the indexable mount can be pivoted, so that a parison in it drops into the pressing mold for pressing by the pressing tool.

摘要:
A lens is disclosed for lighting purposes suited in particular as a lens for a poly-ellipsoid reflector headlamp for imaging the light emitted by a light source and reflected by a poly-ellipsoid reflector for the purpose of producing a predetermined lighting pattern. At least one of the two lens surfaces comprises areas having different optical scattering effects which areas are configured as zones that are transferred from a mold to the surface by a hot-pressing process.
