  • Patent number: 10394041
    Abstract: The disclosure provides to a birefringent polarizer assembly for spatially separating polarization states of a light beam, in particular in the spectral range below 300 nm. The assembly includes a first prism on the light input side and a further prism on the light output side, which are arranged along a principal light incidence direction. The first prism has a first light entrance surface and a first light exit surface. The further prism has a further light entrance surface, facing the first light exit surface, and a further light exit surface. The prisms in each case have an optical principal crystal axis oriented substantially perpendicularly to the principal light incidence direction. The crystal axes of two adjacent prisms are oriented perpendicularly to one another. A normal to the further light exit surface forms an angle not equal to 0° with the principal light incidence direction.

  • Patent number: 7842164
    Abstract: Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.

  • Patent number: 5201944
    Abstract: The present invention relates to a size composition which shows an excellent sizing effect in neutral to weakly acidic papermaking.Alkanol tertiary amine and fortified rosin, incorporated in the size composition of the present invention, even when prepared as dispersions using a dispersant, are extremely poor in sizing performance in the neutral pH range, whereas the size composition obtained by mixing these components in a ratio according to the present invention and dispersing them using a surfactant specified by the present invention offers an excellent sizing in the neutral to weakly acidic pH range.
