Abstract: Disclosed is an optical fiber free from a generation of a microbend during manufacturing, in which an impregnation of hydrogen and/or water to a clad is prevented. An optical fiber having an electrical conduction, a tolerance to heat and a mechanical strength, and a process for making same. The optical fiber includes a silica based glass optical fiber including a core (11) and a cladding (12), a thin carbon coating (14) formed upon the surface of the cladding, and an electrically conductive coating (15-­17) formed upon the outer surface of the carbon coating. The carbon coating functions as a layer for preventing the impregnation of hydrogen and/or water to the optical fiber, and the conductive coating functions as heat tolerance, conductive, and mechanical support member. Preferably, the conductive coating can be materials having a good contact with the carbon coating, high conductivity, high heat tolerance, and high strength, and can be formed as thin as possible. The conductive coating can be formed by a plurality of different metal layers having different thickness.

Abstract: An electronic circuit of a safety ski-binding detects at least the forces and/or torques acting on the leg of the skier by means of at least one transducer. On reaching a predetermined threshold, the circuit energises or de-energises an electromagnet whose armature releases the lock of a sole holder which is preferably stressed by a spring in the direction of its opened position and is held in its closed position by means of a locking device. The circuit and the magnet are supplied by a battery. In order to ensure a reliable release with an essentially constant release characteristic, even in the case of a power failure, a mechanical, pneumatic and/or hydraulic device (8) is provided, which is independent of the electronic circuit, on the one hand is influenced by the sole holder or by a part which is effectively connected thereto, at least over a measurement path, and on the other hand has a separating element (9) which is connected downstream from a shock absorber (11, 13, 24) and can influence the armature (2) of the electromagnet (1), or a part (3) of the locking device, in the sense of releasing the lock of the sole holder.

Abstract: Method for marking an object with a code which can be scanned by means of IR radiation, which code is applied by means of a suitable printing operation directly to a surface of the object, using a printing ink to which a colourless IR-absorption agent is added. All this is done in such a way that the absorption of IR radiation, in the scanned area of the object, in the parts which are not covered with this printing ink with colourless IR-absorption agent is negligible compared with the absorption in the parts covered with this printing ink, while the parts covered with this printing ink remain at least virtually entirely pervious to visible light. By preference the used printing ink is a colourless printing ink, and the code is applied to a coloured or uncoloured background of the object to be printed.

Abstract: 5 n7 An apparatus for removing bulk materials from a laterally enclosed storage area (10) wherein the apparatus may be substantially buried within the bulk material (11). The apparatus includes a support column (16) mounted at a base into a support floor (25). An auger (17) is attached by means of an axial mount at the base of the support column for enabling rotational inclination of the auger from (i) a vertical orientation vertical orientation wherein the auger is nearly parallel with the vertical axis of the support column, (ii) through intermediate angles of inclination (54), to (iii) a substantially horizontal orientation (55) wherein the auger is adjacent to the support floor. The suspension cable (61) is coupled between the support column and auger to enable selective adjustment of auger inclination. A rotational displacement drive (35) is coupled to the support column to rotate the column about its vertical axis, along with the attached auger. A rotational drive motor (51) is mounted at a distal end of the auger. Rotation of the auger, along with revolution of the support column provide for progressive removal of conical layers of surface material with each 360 degree revolution. Continued inclination to the horizontal level enables the total volume of the storage area to be out loaded.

Abstract: This invention describes a femoral twin-stem for a hip endoprosthesis. The lateral stem portion (2,3) and the medial stem portion (4,7) are connected by a centrally located bridge (1). The bridge (1) is designed in such a way that the lateral and the medial stem portions (2,3;4,7) are separated from each other by an antero-posterior proximal slot (5) and an antero-posterior distal slot (6) both extending away from the bridge (1). 
The neck (11) of the femoral twin-stem is connected to the proximal section (2) of the lateral stem portion (2,3). The proximal prong (4) of the medial stem portion (4,7) and the distal prong (3) of the lateral stem portion (2,3) allow for a gradual load transfer to the bone since they can be individually designed with a proper geometry all the way to their respective tips. Gradual load transfer in turn reduces stresses (18,19) in the bone cement mantle (10) and improves the long term results of the hip replacement effected with this femoral twin-stem.

Abstract: A method for laying-down courses of road building material by a mobile finisher provided with a compaction-aggregate, preferably a tamper, and a finisher of this type are described, the frequency of the compactor drive being adjusted as a function of a predetermined laying-down speed and predetermined parameters of the course to be laid down. To avoid irregularities in the course to be laid down, in particular during start-up, it is proposed that the actual laying-down speed be measured by a sensor and the frequency of the compactor drive be altered automatically in accordance with a preset desired-value curve if the actual laying-down speed differs from the predetermined speed. <IMAGE>

Abstract: A device for positioning a body (5) by means of at least one pair of electromagnets (13, 15). A position sensor (29) measures the size of an air gap (23) between one of the electromagnets (13, 15) and a guide beam (1). An output signal of the position sensor (29) is offered to an electronic control unit (35) which passes a control current through the electromagnets (13, 15) in dependence on a difference between the measured and a desired size of the air gap (23). An electrical switch (53) is connected between the control unit (35) and the two electromagnets (13, 15) controlled by the control unit (35), admitting the control current to only one of the two electromagnets (13, 15) in dependence on the polarity of a control signal from the control unit (35). The use of the switch (35) achieves that the control current flows through only one of the two electromagnets (13, 15), so that in a simple manner a difference necessary for supporting the body is achieved between the forces exerted on the guide beam (1) by the electromagnets (13, 15). 
     Since the electrical resistance losses in the electromagnets (13, 15) in such a device are low, the device is eminently suitable for use as an electromagnetic bearing in an optical lithographical device for the irradiation of semiconductor substrates, or in other precision machines.
