  • Patent number: 7465370
    Abstract: An information carrier comprising a support and a receiving layer is disclosed, together with the method of preparation. The information carrier further comprises (optionally personalized) information applied, preferably by ink jet printing, on the receiver layer, and a new type of watermark, obtained by applying pattern-wise a curable varnish and curing it, and by curing an overall applied curable lacquer. One of the varnish and the lacquer have the ability upon penetration into the receiving layer of changing its transparency, thus creating a transparent watermark on an opaque background, or creating a opaque watermark on an transparent background. The finished information carrier is preferably cut in a set of multiple identification (ID) cards.

  • Patent number: 7459691
    Abstract: The invention relates to a cassette, in particular an X-ray cassette, for receiving a storage fluorescent screen. The cassette has on one of its narrow sides an opening through which the storage fluorescent screen is to be inserted into or removed from the cassette. The opening is closable by a flap which is displaceable between a closed position in which it closes the opening and a release position in which it releases the opening for insertion or removal of the storage fluorescent screen. For this purpose the flap is mounted swivellably to the transition between the narrow side of the cassette provided with the opening and the base of the cassette or the cassette lid.
