  • Publication number: 20140152244
    Abstract: In accordance with an example embodiment of the present invention, an apparatus comprises an open frame comprising first and second members respectively comprising first and second channels. The second member is longer than the first member. A support arrangement comprises a base attached to the first member and projects in a rearward direction therefrom. The base is configured to support the open frame in a portrait position when the apparatus is in a first orientation, and to support the open frame in a landscape position when the apparatus is in a second orientation. First and second flanges respectively project in a frontward direction from the first and second members. A detachable wireless charging plate comprises first and second edge surfaces configured to respectively fit within the first and second channels of the open frame. The detachable wireless charging plate serves as a backrest of the apparatus.

  • Patent number: 8133355
    Abstract: The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair (102, 103) is placed in the wet end. The electrode pair (102, 103) is supplied with a current/voltage from a power source (100), so that an electric field is set up between the electrode pair (102, 103), causing the material particles in the pulp suspension in the wet end to be electrically charged in a desired manner and to move in a desired manner in the pulp suspension in the wet end. The current/voltage of the power source (100) is controlled by means of a measuring and control unit (101) so as to cause the material particles in the pulp suspension to be electrically charged and to move in a desired manner, thus allowing the retention, formation and orientation of the material particles in the pulp suspension to be substantially improved.
