  • Patent number: 5641355
    Abstract: An extrusion coater for the production of a magnetic recording medium having at least one coater slot is described, the lower lip arranged in a direction opposite to the running direction of the substrate and displaced forward relative to the upper lip containing, in its interior, a permanent magnet which is oriented approximately parallel to the upper edge of the lower lip and whose field lines are roughly perpendicular to the coating direction of the magnetic dispersion flowing through the coater slot. By means of this arrangement, it is possible substantially to reduce the layer thickness while achieving a satisfactory coating and also considerably to reduce the edge bead.

  • Patent number: 5569522
    Abstract: An anticopying film (2) for covering documents (1) appears opaque in vertical plan view (5) as a result of total reflection for protection against copying and appears transparent in the oblique viewing direction (6), the film having an irregular sawtooth structure (3). This makes it virtually impossible to produce an identical second film with the aid of which, by placing said second film on top, the effect of the anticopying film (2) might be eliminated.
