    • 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.
    • 用于坯料压制玻璃体的装置包括具有用于从玻璃料滴形成型坯的预成型件的第一旋转分度台; 第二旋转分度台具有压制模具和压制工具,用于在预型件中形成之后将型坯压制成最终形式; 以及用于相对于第二旋转分度台移动第一旋转分度台的装置,使得每个预成型件可定位在按压工具和按压模具之间的转移位置。 每个预成型件通过可转位的安装座安装在第一旋转分度台上,用于将其保持在第一水平位置或在远离第一位置枢转的第二位置,使得当预成型件处于转移位置时,可转位的安装件 枢转,使其中的型坯落入用于按压工具的按压模具中。

    • The optical lens, especially for a motor vehicle, is provided with a soft-focus effect, e.g. to soften a light-dark boundary on an illuminated surface. For this purpose the optical lens has an optically active surface (5′) provided with an embossed fine structure (2) extending radially outward in a direction from an optical axis (O) toward an outer periphery (P) in an undulating form and an embossed microstructure (3) superimposed on the embossed fine structure (2). The fine structure (2) has a roughness that is greater than that of the microstructure (3). The fine structure (2) preferably has a roughness of from 1 μm to 10 μm and the microstructure (3) has a roughness (h) in a range of from 0.1 μm to 2.5 μm.
    • 光学透镜,特别是用于机动车辆的光学透镜,具有软聚焦效果,例如, 以软化照明表面上的浅黑色边界。 为此目的,光学透镜具有光学活性表面(5'),该光学活性表面(5')设置有沿着从光轴(O)向波浪形状的外周(P)的方向径向向外延伸的压纹精细结构(2) 压花微结构(3)叠加在压花精细结构(2)上。 精细结构(2)的粗糙度大于微结构(3)的粗糙度。 精细结构(2)优选具有1μm至10μm的粗糙度,并且微结构(3)的粗糙度(h)在0.1μm至2.5μm的范围内。
