  • Patent number: 11820094
    Abstract: The invention relates to a powder press (1) for producing a pressed article from a material that can be pressed, having a press frame (10), an upper and/or lower punch assembly (14) and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit (12) which is operatively connected to the punch assemblies (14) and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies (14) and the die assembly can be moved relative to each other along a pressing axis (18) and pressed against each other by means of the electric drive unit (12). Furthermore, the operative connection between the electric drive unit (12) and one of the punch assemblies (14) comprises a toggle lever drive (16) which moves the punch assembly (14) into a pressing end position along the pressing axis (18).

  • Patent number: 4222343
    Abstract: Coating apparatus for producing multiple coatings on photographic bases wherein a layer of the coating material flows over each of two slideways which slope downwardly in a V form. An intermediate element is disposed in the flow gap bounded by the two slideways. The discharge edges of the slideways and of the intermediate element are disposed at substantially the same level. At this level the various layers of liquid combine to form a multilayer curtain which falls on to a base passing below to form a multiple layer thereon. The intermediate element can be a slot pourer so that the coating material issuing from its slot combines with the coating compositions supplied from the slideways.
