Abstract: An enclosure which has a lead-through for passing a rod-like element through a wall of the enclosure, and a grommet for sealing a rod-like element to a wall of an enclosure, the grommet having a passage for passing the rod-like element therealong through the grommet and the passage having its walls adapted to fit around the rod-like element. The grommet includes a first recess adapted to match at least a rim of a cutout in the enclosure; a second recess, adapted to receive a clamping element which is adapted to secure and seal the rod-like element to the grommet by applying a radial compression to the rod-like element; one split face, which establishes an openable route between the exterior of the grommet and the passage, the split face being provided with sealing elements for an axially directed and radially directed alignment and sealing of the split face.

Abstract: A universal chassis (1) for attaching goods (99), such as a product, box, rack, or structural element, has a base part (10, 100), to which one or several following fastening elements have been connected either detachably and/or fixedly: a mounting slot (2), fastening rail (97), fastening edge (13), fastening lid (203), side fastening element in the lateral plane of the universal chassis (3), intermediate fastening part (98), which can be attached to the goods (99) and the universal chassis (1).

Abstract: The invention relates to a proof testing method and a proof testing apparatus for optical fibre where a fibre (1) is guided to a first pulling device (2) and further to a second pulling device (3) and then onto a reel (11, 12), whereby the pulling devices subject the fibre to a desired amount of tensile strength, as a result of which the fibre breaks if the fibre (1) strength is insufficient. To achieve a continuous pulling and proof testing process, the fibre end is guided in the case of a fibre break between the first and the second pulling device (2, 3) by means of a first channel section (5), which guides the fibre to the second pulling device (3). After the second pulling device (3) the fibre end is guided into a second channel section (8) which is off the normal fibre track and along which the fibre (1) is guided into a scrap fibre processing system. At a desired moment the fibre (1) is guided from the second channel section (8) to the normal track, along which the fibre is guided onto a reel (11, 12).

Abstract: The invention relates to a method and arrangement for levelling out tension variation of an optical fibre when the fibre is wound on or off a reel, the basic tension of the fibre being provided by means of a dancer. To allow tension to be rapidly levelled out, the fibre is arranged to be deflected between two support and guide means by means of a transverse jet of a gaseous medium generated by a nozzle means mounted in a transverse position in relation to the direction of travel of the fibre.

Abstract: A valve system, applicable for instance to analyzers, consists of a plurality of electromagnetically operating clamp valves, purposed to unclamp and/or clamp an elastic tube passing through the valve, thereby respectively turning on or shutting off fluid flow in said tube. The apparatus comprises a magnet table carrying a plurality of electromagnets, a cover part adjacent the magnet table carrying closing pegs movable with the aid of the electromagnets, and a tube cassette between the magnet table and the cover part, in which cassette the tubes may be disposed in a given array for the functions of the analyzer.

Abstract: A procedure for implementing the liquid selection of analyzer liquid dispension, includes the steps of selecting a liquid vessel from among a plurality of such vessels, and taking liquid into the dispensing system for further treatment. The liquid path from the liquid vessel that has been selected is so connected to the dispensing unit that (i) the sealing surfaces constituting the connection do not substantially slide against one another and that (ii) sealing at the connection is accomplished by means of elastic deformation of at least one of the bodies being coupled.
