  • Particle based binding assay
    Patent number: 7709212
    Abstract: The present invention provides a method for detecting the presence or amount of an analyte in a sample, said method comprising: a porous surface to which particles having attached thereto a binding substance, analyte and binding substance coated label particles are added. If said analyte is present in the sample an immuno- or chemical reaction occurs in the liquid phase. The separation of bound complex from unbound material is achieved by using said surface where the separation occurs mainly two dimensionally on the surface of the porous surface (e.g. grid). Interestingly, the disclosed surface enables a separation where said complexes are distributed two dimensionally on the porous surface (e.g. grid), whereas unbound materials are distributed three dimensionally. Accordingly, said surface enables both a two and a three dimensional separation.

  • Beam structure for a web forming machine
    Patent number: 7662261
    Abstract: A beam structure for a web forming machine is arranged to be supported by its end components (10) on the web forming machine. The beam structure includes a casing structure (15) of a thin-sheet material, inside which a stiffener structure (30) is arranged. In addition, the casing structure (15) and the stiffener structure (30) are secured to each other to create a load-bearing beam structure.
