Abstract: The inventive method consists in introducing two connectable end sections of spliceable optical waveguides in a mobile clamping device and in clamping said end sections in such a way that they are oriented at least towards one position which is axial with respect to another. Each clamping device (4, 4?) can slide along an advancing trajectory (5, 5?), said advancing trajectories being more or less in a parallel position to each other. During the advancement of the clamping devices, several processing stations arranged between said advancing trajectories can be sequentially actuated from preparatory operations followed by splicing operations which are carried out on said end sections at the level of the processing stations. The inventive processing stations comprise, in particular a wire skinning station (7), a cleaning station (8) and a length cutting station (9). By the end of the process, after the splicing operation, the spliced optical waveguide is removed from the clamping devices (4, 4?).

Abstract: A pre-fitted optical fiber section (2) is held in a plug ferrule (1) in such a way that it extends from a face (3) up to a lateral fusion access aperture in the plug ferrule (1). From the direction of an entry surface (7) at the cable-end, a bore (6) running coaxially to the optical fiber section also leads into the fusion access aperture. Within the fusion access aperture, the pre-fitted optical fiber section can be welded to the optical fiber (27) of an optical fiber cable (24) in the field. The plug ferrule is assembled from at least two components, of which one (8) possesses the outer jacket serving to center the plug ferrule and the other (10) possesses the fusion access aperture (4) and the bore (6). Both components comprise differing materials, which considerably facilitates manufacture.

Abstract: A protective flap (5) is arranged on the end of a lever arm formed as a flexible spring on the plug casing (2) of a plug (1, 1'), said protective flap covering the face and the end surfaces of an optical fiber. The lever arm is connected to the plug casing so as to be removable, and is shaped and arranged in such a way that the protective flap is pressed against the face under spring tension when in the closed position. With that, the protective flap assumes not only a screening function to guard against the escape of light, but also practically hermetically closes off the face and thus prevents dirt entering between the protective flap and the face.

Abstract: An engagement device ensures that a plug portion (1) is held, secure against tension, in a sleeve portion (3). The engagement device has at least one locking catch (5) which is able to be engaged behind a locking element (6) when the plug portion is completely inserted. To release the lock, a releasing lever (7) is provided next to the locking element (6), with which the locking catch is able to be disengaged from the locking element. This releasing lever is formed as a double armed lever which is able to pivot on the plug portion. Through that, no excessive force must be exerted onto the sleeve portion in order to withdraw the plug portion.

Abstract: For the axial springing of the connector pin (1), the connector pin is held firmly in a receiving socket (3) which is connected via a spring element (6) with the actual connector body (2). The receiving socket, the spring element and at least a part of the connector body are integrally formed. Through suitable choice of material and shape, the spring element (4) obtains the required spring characteristics. By means of this design, the connector has only a few individual components and is easily assembled.

Abstract: The sleeve portion (1) contains a sleeve (2), the sleeve openings of which are overlain by moveable protective flaps (6, 6'). The protective flaps are placed under spring tension and are forced out of the closed position into an opened position during insertion of a plug ferrule (3) into the sleeve (2). The protective flaps have the effect that, when a plug is withdrawn out of the sleeve portion, no light can be emitted from the sleeve opening. The pivotable mounting of the protective flaps ensues between an inner sleeve housing (8) and an outer sleeve housing (9).

Abstract: The connector pin (2) is protected by a lid (6) which is opened into the sleeve portion (3) when the plug portion (1) is slid in linearly. For this purpose, a sleeve portion is provided with a control path, for example in the form of guide grooves (30), which coordinates with the cover (6). When withdrawing the plug portion (1), the lid (6) is once again closed with the aid of the control path.

Abstract: The inclination (6) of the Fiber end surface (4) is arranged in such a way that an edge area (7), which extends through 360 degrees, remains around the inclination. The inclination is separated from the edge area by an annular shaped indentation. In this way the connector pin has on its face (5) a constantly unchanging limit-stop surface in each desired relative position.

Abstract: The core (4), of plastically deformable material, is supported and fastened in the hollow cylindrical outer part (2), of relatively hard material, on a supporting shoulder (6). Moreover, especially good results can be aimed for if the core (4) is slightly mushroom shaped and exhibits a disc (7) with a shank (8). The disc (7) can accommodate temperature determined dilatations especially well.

Abstract: The eccentricity of the core of the light guide fiber relative to the outer casing of the light guide end portion is detected by viewing the end face while simultaneously rotating the light guide end portion. When an eccentricity is detected, the light guide fiber is displaced by impressing an impressing segment into the end face of the light guide end portion until the core of the light guide fiber extends coaxially with respect to the central axis of the light guide end portion. For that purpose the light guide end portion is clamped in an adjusting device under a microscope.

Abstract: The coupling assembly for light wave conductors has a capillary tube which surrounds the light wave conductor and which is received, together with the light wave conductor, by a holder tube. The holder tube is in turn secured in a centering sleeve. The centering sleeve comprises a material with a Mohs hardness which is equal to or greater than 8.5.

Abstract: The present invention refers to a method for the shaping of polycrystalline, synthetic diamond and, in particular, to the production of profiled parts like tools. The shaping process is performed by spark erosion with electrodes shaped accordingly.

Abstract: A light-conductor coupling means for coaxially connecting two optical fibres comprises two cylindrical end members, which contain the optical fibres, and a centering sleeve which receives and centers the end members with a precise fit. The centering sleeve, at its inner surface, and/or the cylindrical end members at their outer surfaces are provided with at least one spiral vent passage. The vent passage permits the air to escape when the two cylindrical end members are fitted together. The vent passage extends over the entire periphery of the inner surface so that the centricity of the arrangement is not detrimentally affected. In order to permit the cylindrical end members to be pushed together with a rapid movement, hollow cavities in the form of annular grooves in which the escaping air is temporarily compressed are also provided.
