Patent number: 5106260Abstract: In a method and an apparatus for singling cards such as check cards or identity cards, each card to be singled is moved beforehand into a singling groove, thereby passing out of the area of a stop holding the stack. The card thus presingled is thereupon taken completely off the stack using a suitable removing sucker. In this way, cards can be singled very reliably and gently.Type: GrantFiled: April 3, 1989Date of Patent: April 21, 1992Assignee: GAO Gesellschaft fuer Automation und Organisation mbHInventor: Werner Obrecht

Patent number: 4892336Abstract: The present invention relates to an antifalsification document having an embedded secutiry thread, and to a method for producing the same. This security thread is transparent and has a printed pattern on one side and, on the opposite side, a lenticular structure coordinated with the printed pattern. Such threads change their appearance when the viewing angle changes. To produce the security threads, a transparent film impressed with the desired lenticular relief is directed to a printing apparatus in exact register via guide elements having a relief structure that is negative with respect to the film impression, and then divided in a cutting apparatus into individual threads.Type: GrantFiled: March 18, 1987Date of Patent: January 9, 1990Assignee: GAO Gesellschaft fuer Automation und Organisation mbHInventors: Wittich Kaule, Jurgen Moll, Gerhard Schwenk, Gerhard Stenzel

Patent number: 4735670Abstract: The disclosure concerns an identification card containing information such as name, account number, photograph of the card owner, etc. The card is protected by a superjacent printed security pattern, such as a guilloche, or other pattern which is difficult to imitate, or a homogeneous printed surface. The information is inscribed into the identification card material through the printed security pattern by a laser beam recorder. The energy of the laser and the colors of the printed security pattern are coordinated with each other in such a way that the laser light is not absorbed by the printed security pattern and the latter is not destroyed by the laser light.Type: GrantFiled: August 25, 1986Date of Patent: April 5, 1988Assignee: GAO Gesellschaft fuer Automation und Organisation mbHInventors: Thomas Maurer, Hans J.

Patent number: 4732410Abstract: An identification card having information applied in the form of patterns, letters, numbers and/or images, formed by interruptions in the homogeneity of different colored layer areas arranged superjacently on the identification card. The colored information can be produced by selectively removing the color layers by means of a controlled laser beam or by blurring or other chemical reactions induced by said beam. Thus identification cards can be produced having a high standard of security in spite of the simplicity of their production.Type: GrantFiled: May 1, 1985Date of Patent: March 22, 1988Assignee: GAO Gesellschaft fuer Automation und Organisation mbHInventors: Hans J.

Patent number: 4629630Abstract: A check paper is being described which is protected against falsifications and forgeries. Crushable micro capsules are being embedded in check paper which contain on one hand a leuco ink and on the other hand a color acceptor. The color acceptor can also be stored in the body of the paper without the use of micro capsules. The leuco ink and the color acceptor react together under color development or color changes if the micro capsules burst through imprinting or other local pressure application to the paper surface. Thus, a character written on the paper surface becomes visible within the body of the paper and cannot be forged anymore.Type: GrantFiled: April 30, 1984Date of Patent: December 16, 1986Assignee: GAO Gesellschaft Fuer Automation und Organisation mbHInventor: Ludwig Devrient

Patent number: 4504357Abstract: A security with a paper substrate which exhibits identifying marks in the form of color patterns. The color patterns are arranged in the substance of the paper substrate in such a manner that the normal structure of the fibres in the substance of the paper layer is not disturbed by the color patterns. In the manufacture of the security, the color pattern is sprayed on to the not yet completely finished non-woven fibre during the formation of the paper sheet, and is preferably sprayed on to a non-woven fibre which is then united to a second non-woven fibre.Type: GrantFiled: October 26, 1983Date of Patent: March 12, 1985Assignee: GAO Gesellschaft fuer Automation und Organisation mbH.Inventors: Hans-Jurgen Holbein, Paul Leiderer, Walter Schneider

Patent number: 4463970Abstract: A data carrier having excitable marking materials to record information in code and further materials to camouflage them, as well as a method of producing this type of data carrier. The coded information is given in the form of the local presence or absence of the excitable marking materials, and is read by detecting the state of excitation, which can only be done with difficulty. The camouflage materials have the function of preventing the detection of the marking material pattern indirectly by means of a chemical laboratory analysis; this camouflage is successful when materials are used which are very similar chemically to the marking materials, and in particular yield the same results as these in a chemical laboratory analysis, but are not excitable with the same means or in the same manner.Type: GrantFiled: December 1, 1981Date of Patent: August 7, 1984Assignee: GAO Gesellschaft fuer Automation und Organisation mbHInventors: Wittich Kaule, Gerhard Schwenk, Gerhard Stenzel
