Patents by Inventor Wangelis Karampougioukis

Wangelis Karampougioukis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10611130
    Abstract: An extruded matt foil has at least one layer in which glass beads are uniformly distributed in a polymer matrix with at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).
    Type: Grant
    Filed: December 5, 2017
    Date of Patent: April 7, 2020
    Assignee: Röhm GmbH
    Inventors: Claude Guénanten, Helmut Háring, Detlef Birth, Max Conrad, Eric Reinheimer, Günther Dickhaut, Ghirmay Seyoum, Wangelis Karampougioukis, Girolamo Musci

  • Patent number: 10466406
    Abstract: A process for producing a light guide plate includes producing a colorless transparent sheet from a colorless transparent material by extrusion with a polishing stack. A printed reflector film is laminated in-line to the colorless transparent sheet. The printed reflector film includes: a thermoplastic reflector film which is opaque white or translucent white and made of a thermoplastic material; and a colorless thermoplastic printed on the thermoplastic reflector film. There is no direct optical contact between the colorless transparent sheet and the thermoplastic reflector film. A glass transition temperature of the printed colorless thermoplastic is above 25° C. and below glass transition temperatures of the colorless transparent material of the colorless transparent sheet and of the thermoplastic material of the thermoplastic reflector film.

  • Patent number: 9567444
    Abstract: The present invention relates to a process for producing transparent polymeric films or plastics moldings of particularly high chemical resistance, having more particularly a very good resistance towards oil-in-water and water-in-oil emulsions, and of high optical quality.

  • Publication number: 20160170128
    Abstract: The present invention relates to novel light guide plates composed of a reflector film, of a transparent sheet and of, situated between these, reactive hot-melts or colourless thermoplastics applied by structured printing. No fixed direct connection exists here between the reflector film and the transparent sheet. Light guide plates, e.g. in backlight units (BLUs) or in light panels, have maximum uniformity of thickness and are composed of colourless transparent materials. Light is input here by way of example from LED or CCFL light sources by way of one or more edges of the light guide plate. On at least one surface of the light guide plate there is a structure which scatters the light. When a light beam is incident on the said structure, it is scattered at an angle smaller than the angle of total reflection, and is thus emitted from the plate. The light is emitted at both sides of the plate, and on one side there is therefore mostly a white reflector film which is not in optical contact with the plate.
