  • Publication number: 20140125050
    Abstract: A sheet document is based on a one-pieced, coextruded composite strip layer having a thickness of 10 to 110 ?m defining over its area at least two different materials that are configured side by side as strips. At least one of the strips is transparent or translucent and at least one strip opaque. On the composite strip layer there is applied an ink-receiving layer and/or a printed pattern that has a recess that at least partly is configured above a transparent/translucent strip and together with the non-covered region of the transparent/translucent strip forms a window.

  • Patent number: 8695883
    Abstract: A data carrier card and a method for producing a data carrier card, in particular a chip card or magnetic stripe card. The data carrier card has a card body having one or several foils, where the foil or at least one of the foils is a coextruded foil having at least two areas with different material properties. The use of coextruded foils makes it possible to form in a simple manner different areas in the card body which differ from each other in material quality. In particular, it is possible to form for example a data carrier card with a card body having a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the surface of the card body.

  • Patent number: 7503503
    Abstract: A card laminate is produced from a centrally disposed foil laminate (1) consisting of an interior layer (2) with a metal layer (3) and with two exterior transparent plastic layers (4a, 4b), and two exterior plastic films (5a, 5b) of which at least the plastic film (5a) overlying the metal layer (3) is transparent and carries a print (6a). If the print (6a) is on the exterior, a transparent cover layer (7a) is furthermore provided. Materials and layer thicknesses are preferably selected symmetrically to the interior, metallized layer (2, 3) in order to reduce warping effects.

  • Patent number: 6135503
    Abstract: The invention relates to an identification document, such as a passport or the like, which consists of a plurality of sheets bound into a book at a seam. At least one of the sheets forms a data sheet provided with information and consisting at least of two layers, at least one of the layers being transparent. The format of the layers is selected so that they protrude beyond the area of the seam thereby ensuring a connection of the data sheet with the other sheets of the identification document in the area of the seam. The layers are connected into an inseparable laminate in the area of the information but do not stick together in the area of the seam.

  • Patent number: 4788358
    Abstract: A process for the manufacture of 1,2-dichloroethane from ethylene by reaction with hydrogen chloride and inert gases containing oxygen, and also by reaction with chlorine, is described. The two chlorination reactions are carried out successively at 180.degree. to 360.degree. C. and under a pressure of 0.09 to 1.1 MPa in a common reaction space containing fluidized catalyst particles. A stoichiometric excess of ethylene is employed for the first chlorination reaction. The heat formed in the reaction space is removed by indirect cooling. The process is simple in terms of apparatus and permits a better re-use of the total heat of reaction of the chlorination of ethylene.

  • Patent number: 4747914
    Abstract: A process for the purification of 1,2-dichloroethane is described, in which the crude product, containing not more than 3% by weight of high-boilers, is distilled in a first column at 125.degree. to 180.degree. C. in such a way that the bottom product contains not more than 7% by weight of high-boilers. The purified, vaporous 1,2-dichloroethane discharged at the head of this column is used to heat product streams containing 1,2-dichloroethane. The bottom product from the first column is distilled in a second column, advantageously at a pressure of 5 to 40 kPa, together with a feed composed of vaporous 1,2-dichloroethane obtained from the reaction of ethylene with chlorine. The process makes it possible to purify 1,2-dichloroethane with a saving in energy.
