Abstract: The invention relates to a method for fabricating an optical plug connector, according to which the optical waveguide is immersed with the exposed optical fiber into a powdery adhesive and is withdrawn from the same, whereby particles of the powdery adhesive remain adhered to the surface of the fiber. The fiber with the adhered particles is then inserted into the bore of the ferrule of the plug connector and is fixed therein. The ferrule is heated to a temperature greater than or equal to the melting temperature of the adhesive and is maintained at this temperature.

Abstract: An elastic roller casing is replaced on a roller core by first removing the casing and a portion of a fastening layer, thereby reducing at least part of the fastening layer in thickness, centering a new casing on the core over the partly removed fastening layer, and then filling any remaining intermediate space between the partly removed fastening layer and the casing with a material to connect the casing to the partly removed fastening layer.

Abstract: The plug connector has a first connector element (2) and a second connector element (3), which are connected to one another by means of a coupling member (26). The two connector elements (2, 3) form an outer conductor (9) and an inner conductor (10). A contact element (16) which is in the form of a cup spring and exerts an axial force on the connector elements (2, 3) in order to compensate for tolerances is arranged between the two outer conductor parts (11, 12). The contact element (16) forms a closed circular contact surface (A, B) with the respective outer conductor parts (11, 12). The plug connector can be produced at low cost and has low RF characteristics, in particular good passive intermodulation and RF emission.

Abstract: In order to improve visibility and hence to reduce the risk of accidents, a rope, for example a wire rope, is equipped with a number of luminous elements. A luminous element may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids and preferably within the theoretical rope circumference. The luminous element may also itself be composed of luminous elements which are twisted together, are twisted or are laid. For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh. The luminous element is intended to be connected to a source. In the state when it is fed, the luminous element is actively luminous. Owing to the improved visibility, rope lights may be used not only for a safety function but also for an aesthetic appearance.

Easy and stable bonding is achieved by using a solid chemically reactive adhesive (19) which is reacted when brought into a liquid state and which enables a temperature-resistant connection.

Abstract: In a process for the irradiation of strand-shaped irradiated material (19; 19a-e), in particular cable insulation or sheathing (31) capable of being cross-linked by irradiation, or tubes, hoses, or profile elements capable of being cross-linked by irradiation, with electron beams impinging transversely to the longitudinal axis of the irradiated material (19; 19a-e), which strike the irradiated material (19; 19a-e) from two fixed irradiation directions (R1, R2), located at an angle to one another which is other than zero and for preference is a right angle, a uniform irradiation is achieved in a simple manner in that a scanned electron beam (17) is created from an electron beam (11) in a scanner (12) by means of a scan device (13), which by means of a temporally-actuated back-and-forth slewing movement in a prescribed angle range creates a radiation fan transversely to the longitudinal direction of the irradiated material, and that the scanned electron beam (17) is deflected by a deflection magnet (16, 16&prim

Abstract: The invention relates to an optical connector for detachably connecting a circuit board to a backplane. The inventive connector comprises at least one plug (10A) and at least one socket (10B) for receiving the plug (10A), whereby the socket (10B) comprises an outer housing (12) and an inner housing (13). Said inner housing (13) is mounted in the outer housing (12) such that it can be displaced in the direction of plug insertion, and a locking means (25,26) prevents the inner housing from being displaced inside the outer housing (12). In addition, unlocking means (20) are assigned to the plug (10A) which unlock the first locking means (25,26) when the plug (10A) is completely inserted into the socket (10B). Second locking means (20,21,23,24) are assigned to the plug (10A) which interlock said plug (10A) and socket (10B) when the plug (10A) is completely inserted. The aim of the invention is to obtain a compact construction and to increase the versatility of the plug system.

Abstract: The fine protection circuit arrangement is to reduce the remaining residual impulses on gas tube charge eliminators. This is to be achieved by means of a cascading of a gas tube charge eliminator or a .lambda./4 shorting stub with a fine protection circuit. The fine protection circuit connected to the gas tube circuit eliminator or .lambda./4 shorting stub reduces the relatively high residual voltage at the output of the gas tube charge eliminator or .lambda./4 shorting stub to a minimal value.

Abstract: The housing bore (5) is substantially widened in the shape of a step at its edge and the outside diameter (A) of a support plate is widened correspondingly. The contact surface (8) of the housing (2) is reduced in accordance with the step-shaped widened part (7) to form comparatively narrow annular surfaces. An advantage of this is that passive intermodulation can essentially be prevented by the reduction of the contact surface.

Abstract: An EMP-eliminator is to be created which is simultaneously applicable for multiple frequency bands and highest frequencies and at the same time allows transmission of AC/DC supply voltages. For this purpose a casing (20) set in an outer line (10) is provided as well as a line (24) connected in an electrically conductive manner to an inner line of a coaxial line (30). The line (24) is connected in an electrically conductive manner with the equipment casing (20) or its face side via a gas filled overvoltage suppressor (28). The gas eliminator (28) is set into a threaded cover and thus can be exchanged. Between the equipment casing (20) and the line (24) several bushes (25,26) connected electrically to the line are provided. The length of the line (24) corresponds to the .lambda./4 length of the lowest transmitted frequency band. Several serially connected resonant cavities result which are matched in their length to different midband frequencies.
