Abstract: An apparatus for manufacturing a medication comprising an ejector unit adapted for ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. The ejector unit comprises a capillary and a tubular piezoelectric actuator surrounding at least a part of the capillary. The apparatus further comprises a control unit adapted for applying an electric signal to the piezoelectric actuator which, in response to the electric signal, is adapted to generate a compressional wave in the capillary for ejecting the predefined amount of the drug via an orifice of the capillary. Moreover, a method of manufacturing a medication is provided, the method comprising ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. Furthermore, a medication is provided comprising a solid carrier substrate, and a predefined amount of a drug ejected with a liquid component to the solid carrier substrate by an ejector unit.

Abstract: The method serves for the altering of suspended paper fibers or pulp fibers, in particular to increase the strength of the paper made from these fibers. Two refining surfaces are pressed toward one another and moved such that a relative speed prevails between the refining surfaces and the pulp in the refining zone which is as low as possible. The method can be carried out particularly easily with refining bodies which carry a refining surface and which are rolled off on the inner side of a refining drum carrying the refining surface.

Abstract: The present invention provides a process for sizing in the production of paper, cardboard, paperboard and other cellulose-containing materials with and without filling materials and/or pigments by natural or synthetic sizing agents under neutral to weakly basic pH conditions without the use of aluminum salts, wherein sizing is carried out with a combination of natural or synthetic sizing agents with a cationic dicyandiamide resin.

Abstract: A method for the production, without thermal treatment, of an anti-reflection coating on surfaces of optical elements of transparent, thermally sensitive material such as organic polymeric plastic material which comprises coating the surface with a layer of silicon oxide by vaporizing said silicon oxide by applying the energy of an electron beam thereto under vacuum in such manner that the vaporized molecules are ionized by said beam and are deposited on said elements in ionized condition. A multi-layer coating may then be applied by depositing with an increasing rate on said coating a layer of a substance of higher refractive index than that of said plastic material while continuing the deposition of the silicon oxide, and then depositing thereon a final layer of anti-reflection material such as silicon oxide. The substance of higher refractive index may an oxide of cerium, tantalum, titanium or zirconium.
