Abstract: A box coating apparatus for coating of substrates comprises a vacuum chamber which contains an evaporation source. A substrate holder is disposed vis-à-vis to the evaporation source so that evaporated material can impinge on substrates held by the substrate holder. Besides the evaporation source and the substrate holder, at least one further functional component is provided, namely a Meissner trap and/or a high vacuum valve mechanism, to which a shield arrangement is assigned to prevent evaporated material from impinging on said component. This shield arrangement has a shutter portion which can be moved from a closed shielding position in which it covers a passageway through the shield arrangement and serves to shield said component, to an open pumping position in which it substantially clears the passageway to allow essentially free passage for gases and vapor, and vice versa.

Abstract: A box coating apparatus for vacuum coating of substrates has a vacuum chamber containing an evaporation source and a substrate holder formed as a dome related to the evaporation source and rotatable about an axis. A masking arrangement is located in between for partially shadowing the substrates on the substrate holder relative to the evaporation source. The masking arrangement comprises a fixed masking portion stationary in the vacuum chamber, and a plurality of gradient sector portions carrying gradient shields assigned to the substrates on the substrate holder, for forming a gradient mask. The gradient sector portions can be rotated about the axis between a gradient mask open position where they are stored behind the fixed masking portion, and a gradient mask closed position where they are spread like a fan between the evaporation source and the substrate holder.

Abstract: The present invention relates to mixtures, preferably sealing pastes, particularly preferably shield tail sealing pastes, and the use of the mixtures according to the invention for sealing construction elements and/or construction machines, in particular for preferably temporary sealing of the transition between shield tail of a tunnel boring machine and the pipe lining or tubbing lining of the tunnel securing means.

Abstract: The present invention relates to rifaximin polymorphic forms ?, ? and ?, the processes for their preparation and the use thereof in the manufacture of medicinal preparations for the oral or topical route.

Abstract: The disclosure refers to biologically pure cultures of two strains of Bifidobacterium Longum named W11 and W11a and deposited at the Belgian Coordinated Collections of Microorganisms (BCCM) that has registered them under the accession numbers LMG P-21586 and LMG P-21587. They are used as probiotics within preparations of pharmaceutical or alimentary products to help the gastrointestinal health and to prevent and treat the intestinal pathologies.

Abstract: Crystalline polymorphous forms of the rifaximin (INN) antibiotic named rifaximin ? and rifaximin ?, and a poorly crystalline form named rifaximin ? have been discovered. These forms are useful in the production of medicinal preparations for oral and topical use and can be obtained by means of a crystallization process carried out by hot-dissolving the raw rifaximin in ethyl alcohol and by causing the crystallization of the product by the addition of water at a determinate temperature and for a determinate period of time. The crystallization is followed by drying carried out under controlled conditions until a specific water content is reached in the end product.
