    摘要: A screen element for motor vehicles having a piece of flat material extending in a surface area. The piece of flat material has strands which are inherently stiff to enable the flat material to stand alone without a frame. The strands also provide primary stability for the screen element. A frame on at least one edge area of the piece of flat material provides secondary stability for the screen element.

    摘要: Glyceric acid compounds of the formula (I) R1R2C(OH)—CR3(OH)—COOX  (I) where R1, R2 and R3 are independently hydrogen, C1-12-alkyl, C6-12-aryl, C7-13-alkaryl or C7-13-aralkyl and X is hydrogen, an alkali metal, an alkaline earth metal/2 or NH4, are prepared by saponification of glycidic acid compounds of the formula (II) where Y is NH2 or OR4 in which R4 is C1-12-alkyl or C7-13-aralkyl, with ring-opening addition of water onto the epoxide ring. Preferably, Y is NH2 and the glycidamide of the formula (II) which is used is prepared by reacting acrylonitriles of the formula (III) R1R2C═CR3CN  (III) with hydrogen peroxide.

    摘要: A shadow mask for color picture tubes has a cathode-side surface covered with a heat-insulating layer, an electron reflecting and absorbing layer, and a heat-emitting cover layer. Some of the electrons are reflected while others are absorbed in the cover layer and transformed to heat, but the heat does not act directly on the mask and is emitted into the interior of the tube. Local temperature differences which particularly occur with high contrast pictures and cause partial doming of the perforated mask are reduced.
