Abstract: The invention is related to a permanent magnet rotor having a shaft, a hollow cylindrical permanent magnet and an elastic connecting medium between the shaft and the permanent magnet. The permanent magnet is arranged co-axially around the shaft. The task of the invention is to ensure that the permanent magnet is mounted securely, that it is not damaged during large temperature fluctuations, and that it is not deflected impermissibly from the axis of rotation in case of heavy radial load. A simple and cost-effective installation process is used in which a safe mechanical connection between the shaft and the permanent magnet is guaranteed through the entire life. According to the invention, this task is performed by virtue of the fact that an elastic connecting medium is arranged along the periphery of the shaft at several first areas in which the distance between the shaft and the permanent magnet is enlarged.

Abstract: A microbicidally coated article, especially a container, having on at least part of it a coating comprising an organically modified inorganic matrix comprising silver colloids which is obtainable by application of a coating composition comprising a) a hydrolysate or condensate based on at least one hydrolysable silane with at least one non-hydrolysable substituent and b) a silver compound to the surface of the article and treatment with heat and/or radiation to form the silver colloid coating. Articles coated in accordance with the invention are therefore particularly suitable for purposes of disinfection, preservation, cosmetic, pharmaceutical or medical purposes. Articles from the pharmaceutical or medical sector, especially containers for pharmaceuticals or articles or components which come into contact with the human body and are required to be free from germs, are preferred fields of application.

Abstract: A process for producing a crystalline substrate with an optical multi-layer system thereon and the crystalline substrate obtainable thereby. The process comprises the successive application of at least two free-flowing compositions which comprise nanoscale inorganic solid particles comprising at least one of a polymerizable and a polycondensable organic group to a surface of the crystalline substrate and the polymerization and/or polycondensation of the organic groups of the solid particles to form organically crosslinked layers on the substrate and a single-stage thermal consolidation of these layers with a burnout of organic constituents thereof. The at least two compositions give rise to layers with different refractive indices.

Abstract: This invention relates to a connector (1) for connecting a dialysate port (31) of a hemodialysis machine with a dialysate-carrying line. The inventive connector (1) has a recess (6, 6?) with a shift element (3) on the end (4) which accommodates the dialysis machine port (31), whereby the shift element (3) is accommodated in the recess and is displaceable between a first position and a second position perpendicular to the direction of the lumen (8) on this end (4). The shift element (3) does not pass through the lumen (8) in the first position. In the first position, the lumen (8) is constricted so that the connector (1) with the shift element (3) can be placed on the dialysate port (31), and in the second position it can be locked on the dialysate port (31) by means of an undercut (30) thereon. The inventive connector is suitable for production as a disposable item in comparison with the widely used Hansen coupling.

Abstract: A method is provided for transmitting control information between a line-switching and a packet-switching communications network. A signaling connection is set up in a packet-switching network in order to transmit signaling packets which form connection-independent control information which relates to at least one service feature in a line-switching communications network so that at least one service feature of the line-switching communications network may be used in the packet-switching communications network by means of the control information independently of the connection.

Abstract: A window assembly which includes at least some components which may be assembled in a snap-fit manner. In certain example embodiments, a combination of rotation/pivoting insertion, and a snap-fit assembly engagement of one or more components may be utilized in assembly. For example, a component may be engaged with a portion of another component, and then rotated and/or pivoted about a pivot axis until a portion of the component becomes engaged with a part of the window in a snap-fit manner. The combined use of rotation/pivoting about a pivot axis and snap-fit engagement allows for self-alignment to be realized during assembly thereby simplifying the assembly process.
