    摘要: The optical device comprises a lighting unit with two light sources (1) with reflectors (2), whose optical axes (11) are inclined towards one another, with prism pairs (3, 4) for forming two parallel image channels (10, 11) arranged in the optical path and a supplementary lens arranged after a basic optical (12) of a commercial projector for the lateral expansion of the linearly compressed individual images and lenses (A, B, C) for the distortion-free superwide angle imaging of the image pairs on a spherically curved surface. By means of this optical device, a normal commercially available cine projector can be upgraded to a projection apparatus for stereoscopic, linear anamorphotically compressed image pairs on an extremely large, spherically curved wide-screen surface.

    摘要: An apparatus for use during continuous casting for the introduction of a metallic, typically steel melt into the casting head of a continuous casting mold, comprising a substantially tubular-shaped portion which directly merges with a pouring or casting vessel, the cross-sectional area of the tubular-shaped portion being greater than the cross-sectional area of the pouring outlet at the casting vessel. A chamber-like portion of larger cross-sectional area merges with the tubular-shaped portion. The chamber-like portion is equipped with a multiplicity of neighboring openings, the individual cross-sectional area of which is considerably smaller than the cross-sectional area of the tubular-shaped portion.
