Title: Cold chamber pressure die casting machine - with finishing stations in movable die half
Inventor: BAUR JOSEF
IPC: B22D17/00
Filed: 1972-09-22
Abstract: The machine comprises a stationary and a displaceable die half of which the latter is axially rotatable round an axis parallel to the direction of movement of the movable die half.

Abstract: Phoographic production of a contour image, e.g. dyeline print with contour lines a relative low opacity in an optically dense background of a recording layer comprises (a) image-wise illumination of a recording layer, containing particles of intimately mixed N-vinyl carbazole and CBr4 in effective contact with a dye base and dispersed in a hardenable, hydrophylic colloidal binders, with active electromagnetic radiation of sufficient intensity to obtain a copying image having contour lines at the edges of the characteristic image of such a colour that it differs from that of the centrally situated parts of this image. (b) uniform illumination of the recording layer with active electromagnetic radiation which produces a colour in the initially non-illuminated parts and therefor does not affect the contour lines. (c) uniform heating of the recording layer to 100-150 degrees C whereby the regions thereof corresponding to the contour lines are bleached.

Title: Sunlight shielding window blind - two horizontal zebra-striped parallel sheets over guide-rollers and crosswise slats at top and bottom
Inventor: FISCHER KARL
IPC: E06B9/24

The winder may be manually operated, or an opto-electric device be connected to a stepping motor incorporated in a pipe forming the crosswise strip. In the case of larger plastic window blinds, the mechanism may be fitted externally.
