Abstract: A device and method are for separating at least one optical fiber. A swivelled element and an asymmetric anvil are used so that a section of the fiber is contacted only in two positions that are substantially insignificant for the tensile strength of a spliced fiber. In one position, the glass fiber core of the section of the fiber is protected from damages by a fiber sheathing. In the other position that is contiguous to the position of separation, mechanical damages are of minor importance since they are at least partially repaired by the heat produced during splicing.

Abstract: A device is for actuating the flaps of an optical waveguide splicer. The device includes a wind protection flap that can be rotated around a first rotational axis between a closed state and an open state, a first holding flap that's is arranged underneath the wind protection flap on a side of a splicing location and can be swiveled around a second rotational axis between a closed state and an open state and a second holding flap that is arranged underneath the wind protection flap on the remaining side of the splicing location and can be swiveled around the second rotational axis. The wind protection flap is provided with a first coupling device via which the first holding flap and/or the second holding flap can be coupled to the movement of the wind protection flap from the closed state into the open state.

Abstract: In order to fix mutually parallel light-guide ends in a clamping device, it has to be ensured, when using a standard clamping device for different numbers of light-guide ends, that the clamping device is positioned differently depending on the number of light-guide ends. Prior-art apparatuses are of very complex design and are difficult to use. The invention specifies an apparatus which is of straightforward design and in which, depending on the number of light-guide ends which are to be clamped, the clamping devices is fitted in each case in mounts assigned to the number of light-guide ends. The mounts are advantageously arranged here in the form of a centering body which, by rotation through 90° in each case about its longitudinal axis and/or through 180° about a transverse axis perpendicular to said longitudinal axis, is brought into a total of eight different positions. This provides fixedly predetermined mounts for a total of eight different numbers of light-guide ends.

Abstract: A splicing device for welding optical fibers in or close to optical components, in particular optical fiber plug connectors, comprises a first receptacle for the optical component and the associated first optical fiber, an axial adjustable second receptacle for the second optical fiber, an optical device for observing the optical fiber ends to be welded, and two electrodes arranged at a distance from each other, with the first receptacle being mounted so that it can pivot about a pivot axis that is aligned parallel to an axial direction in such a way that the end of the first optical fiber that is located in or close to the optical component can be pivoted in between the two electrodes.

Abstract: A sorting installation, in particular for mail, comprises a plurality of conveyed item carriers, circulating on at least one conveying mechanism, for receiving, transporting and controllably delivering the conveyed items. Each conveyed item carrier has a fixedly arranged wall part and a movably arranged wall part. The movably arranged wall part forms in a closed position together with the fixedly arranged wall part a cross-sectionally U-shaped or V-shaped receiving pocket for the conveyed items. The movably arranged wall part forms in a delivery position together with the fixedly arranged wall part a downwardly open delivery slot for the conveyed items.

Abstract: A sorting installation comprises a plurality of conveyed item carriers, circulating on at least one conveying mechanism, for receiving, transporting and controllably delivering the conveyed items. The conveyed item carriers are fastened by pairs on circulating transport carriages of the conveying mechanism. The transport carriages are guided by rollers on two profiles aligned at a vertical distance in relation to each other and extending in the transporting direction. The transport carriages are driven by an endlessly circulating transporting, cable. The conveying mechanism according to the invention forms, with little constructional complexity, a reliable transporting system by which the conveyed items can also be transferred to sorting containers arranged on different levels.

Abstract: The sorting apparatus includes a plurality of conveyable-article carriers (FT) which circulate on at least one conveying device (FE) and are intended for receiving, for transporting and for discharging, in a controllable manner, the conveyable articles to sorting containers (SB),the conveyable-article carriers (FT) circulating, via at least one vertical deflection of the conveying device (FE), in at least two planes (E1, E2), andthe sorting containers (SB) being provided in at least two levels (ET1, ET2) assigned to the planes (E1, E2) of the conveying device (FE). The guidance of the conveying device (FE) in at least two planes (E1, E2), and the provision of sorting containers (SB) in at least two levels (ET1, ET2) assigned to said planes (E1, E2) makes it possible, with the same surface area on which to set up the sorting apparatus, for the number of sorting containers (SB) available for sorting purposes to be doubled or multiplied.

Abstract: In an installation for alignment of an optical waveguide, particularly a monomode optical waveguide, for splicing purposes a rotary device grasping the optical waveguide is provided. This rotary device has at least one support plate resting against the optical waveguide which, in relation to the optical waveguide, is displaceably mounted in a tangential direction.

Abstract: An apparatus for attaching a cable to a messenger wire utilizing clip elements characterized by a frame having an arrangement for supporting the apparatus for movement along the wire, a feed arrangement for feeding individual clips which are interconnected in a tape form to a severing shearing arrangement and then applying the clips onto the cable and wire positioned below the cable and wire, a double-belt drive arrangement for engaging the free ends of the outside of the clips and moving the free ends in contact with the messenger wire, a folding arrangement for clamping the free ends of the wire together and folding them into a folded connection.

Abstract: A device for observing the ends of optical waveguides, which ends are being adjusted relative to each other for splicing purposes, characterized by two separate microscopes arranged to view adjustments along two perpendicularly extending directions. Each of the microscopes has a mirror arrangement for bending the optical paths onto a common intermediate image plane and the microscopes have a common eyepiece for observing the common intermediate image plane so that adjustments along both directions can be observed without changing eyepieces. Preferably, a diaphragm is provided to be alternately moved into the path of one microscope to block the vision while observing the view of the other microscope.

Abstract: A device for splicing light waveguides, such as optical fibers, having an internal sheath and an outer sheath, characterized by an arrangement for clamping each of the waveguides by engaging their sheaths and lowering the unsheathed end portion into a centering groove where the ends are heated and fused together by an alternating current discharge path. The required convergence and alignment of the light waveguide ends during the welding step are automatically controlled by an advanced arrangement which is sequentially controlled with the welding step. Subsequent to the gearing of the ends, the clamping element releases the waveguides adjacent to the fused joint and are moved by a restoring arrangement to stretch the joint into a straight line position.
