  • Publication number: 20130277957
    Abstract: A security feature for protecting valuable documents, in particular for ensuring the authenticity of valuable documents, comprises a luminescent pigment which has a host lattice doped with a first luminophore and a second luminophore, with an excitation energy of the first luminophore being transferable to the second luminophore. However, in the case of the luminescent pigment according to the invention, the excitation energy is not transferred completely from the first luminophore to the second, but rather only partially. The incomplete transfer of the excitation energy is achieved by selecting suitable amount-of-substance fractions of the first and the second luminophores on the luminescent pigment. As a result of the incomplete transfer of the excitation energy, the luminescent light that is emitted by the luminescent pigment also has, in addition to a luminescence peak of the second luminophore, a luminescence peak of the first luminophore.

  • Patent number: 8561980
    Abstract: In an apparatus for singling sheet material, multiple picks are avoided by a retaining device ensuring that sheet material entrained with the sheet to be singled is retained not only on one side but also on the other side of the sheet to be singled. While the first retaining device is located opposite a singling gap of the singling device and is continually effective, the second retaining device acts before, or in, the singling gap from the other side of the singling gap and is only activated after the sheet to be singled is reliably grasped by the singling device, and deactivated when it has left the singling gap.

  • Patent number: 8544733
    Abstract: A method is suggested for the simultaneous personalization of several portable data carriers (2) respectively having at least one integrated circuit (6) for storing and/or processing information. According to the invention a unidirectional protocol serves for transmitting an identical personalization signal to several portable data carriers (2). These detect personalization data on this basis and store them in the integrated circuits (6). Preferably adapter elements (100; 101; 102) are used, which can accommodate at least one data carrier (50) and which are equipped with first interfaces (140; 150) for communicating with a reading device (20; 21; 22) and with second interfaces (120) for communicating with the accommodated data carrier (2). In a variant the portable data carriers (1) are transported in a transport device (600) which, at least temporarily, electrically contacts the contact area (9) of the portable data carriers (2) by means of a contacting unit (604).

  • Patent number: 8544721
    Abstract: The invention relates to an apparatus for processing bank notes, in particular a compensation unit for adapting the bank-note stock of a recycling apparatus. In recycling apparatus standing in the cash offices of retailers a lack of bank notes of small denominations occurs quickly. In order to render the filling and emptying of the bank-note stock of recycling apparatus easy and safe, and to extend the time intervals for refilling and emptying recycling apparatus and thereby operate them in an economically sensible fashion, a compensation unit is connected to the recycling apparatus, in which bank notes of certain types are stored. It is possible to both transfer bank notes from the recycling apparatus to the compensation unit and to feed bank notes from the compensation unit to the recycling apparatus.

  • Patent number: 8544630
    Abstract: The invention relates to a method and an apparatus for checking documents of value which have a security element with several magnetic areas, including at least one high-coercive magnetic area, at least one low-coercive magnetic area and at least one combined magnetic area which contains both the high-coercive and the low-coercive magnetic material. After the magnetization of all magnetic areas in a first direction, first magnetic signals of the security element are detected with a first magnetic detector. After a subsequent second magnetizing, which is effected antiparallel to the first magnetizing and magnetically reverses only the low-coercive magnetic material, second magnetic signals of the security element are detected. For identifying the magnetic areas, the second magnetic signals or a signal derived therefrom are compared with two thresholds.

  • Patent number: 8524039
    Abstract: A screen for producing two-level watermarks is produced by completely closing part of the screen with a viscous sealing compound, which is subsequently cured actively or passively. At the thus closed partial areas of the screen, paper deposit is hindered during papermaking so that the finished paper appears light in transmission in the areas. A mask is used for exactly positioning the sealing compound in the partial areas of the screen and/or for curing the sealing compound only in the given partial areas, whereby in the latter case the uncured areas of the sealing compound are washed out.
