摘要： An electric power cable of the kind having at least one metallic conductor (1), optionally a conductor screen (2) of semiconductive material, and insulation (3) all enclosed in an earth screen comprising wires (5) or narrow tapes and a sheath comprising polymeric material is characterised by a sheath construction comprising a first extruded polymeric layer (8) which encloses the earth screen (5) of the cable without filling the gaps between the components thereof (the wires or strips), a second extruded polymeric layer (12) enclosing the first (8) and between them and bonded to both of them a moisture barrier laminate comprising a metal foil layer (10) coated on each of its major faces with a polymeric material (11) compatible with the material of the extruded layer (8, 12) it contacts. This increases the resistance of the cable to impact, compared with constructions in which a moisture barrier foil layer is applied directly over the screen wires, and allows the cable to be used in applications that hitherto required a metal sheath.

摘要： An access trolley for use with an overhead power line, comprises: (i) a cradle (2) for an operator; (ii) one or more wheels (30) attached to the cradle for supporting the cradle on the line, the or each wheel being located above the cradle to allow the cradle to hang below the line, and having a pneumatic tyre (26, 28) for distributing the weight of the trolley on the line; and (iii) means (18) for driving the trolley along the line. Preferably the tyre of the or each wheel is inflated to a relatively low pressure, for example not more than 200 kPa to increase the linear distance and in order that the maximum pressure that the tyres exert on the line due to the weight of the trolley and load is not more than 20 kPa. By such means, damage to any optical line that may be wrapped along the line, due to the weight of the trolley, will be prevented or reduced.

摘要： Capacitance transducer apparatus, for example for measuring blade tip clearance in a jet engine of gas turbine, comprises an oscillator (14) connected by a cable (6) to a capacitance means such as a probe (4). The cable is tri-axial comprising an inner conductor (22), an outer protective layer (24) and an intermediate layer (26) between the outer layer and inner conductor, the inner conductor, intermediate layer and outer layer all being electrical conductors. The intermediate layer (26) consists of a material that is different to that forming the outer layer and is of relatively high electrical conductivity. The resistance of the intermediate layer is preferably less than 1 Ohm metre , and especially les than 0.1 Ohm metre , which may be achieved by forming the intermediate layer from a nickel based material, and especially from pure nickel. The reduction in the intermediate layer resistance can lead to higher sensivity of the apparatus by enabling any guard driver amplifier (165) in the apparatus to drive the capacitance over the full length of the cable.

摘要： A method of installing a resistive element (12) along part of an optical cable (14) that extends between, and is supported by, towers of an overhead electrical power transmission system, comprises attaching one end of the element to the optical cable at a tower, feeding the element out along the cable from the tower, and attaching intermediate parts of the element to the optical cable if necessary. The method is characterised in that: (i) the optical cable is earthed at a location adjacent to the tower by attaching to the cable a grounding device that is electrically connected to the tower; (ii) the resistive element is attached to the optical cable at a position on the optical cable between the tower and the location at which the optical cable is earthed by the grounding device, and is fed out along the optical cable from that position; (iii) as the resistive element is fed out along the optical cable, it contacts the grounding device which provides a path to earth for induced electrical currents thereon.

摘要： An optical network includes a plurality of branches (16, 18, 20, 22) in an optical fibre line between a station-end (1) and a plurality of end users (2, 3, 4, 5), and traffic is modulated at one or more optical wavelengths. The network includes in the region of each end user a combination of reflectors (32, 33, 34, 35) which create a reflection pattern that is unique to that end user. By having a unique reflection pattern it is possible to identify a relatively large number of end users (and other points in the network) using only a relatively small number of different wavelengths. It is possible to employ only a single wavelength using reflectors that are separated from one another so as to generate a unique pattern of reflections in the form of a binary coding.

摘要： An end face (6) of an optical fibre (1) has a Bragg grating formed thereon. An arrangement incorporating such a fibre has a plurality of detectors (24, 26; 44, 45, 46; 28, 30) located at the end face of the fibre to detect light emerging at different angles with respect to the axis of the fibre. The fibre carries optical signals at at least two different wavelengths. The signals are diffracted by the Bragg grating so that different signals are detected by the detecting means. A similar arrangement can be used for demultiplexing signals at different wavelengths, or in sensing applications where light of different wavelengths is used to carry signals with information about the measure and reference signals.

摘要： A conductive polymer comprises chains composed of resonant (aromatic and/or heterocyclic) rings in which conjugation extends from end to end of the molecule and cross-links between these chains which consist of aromatic groups conjugated to the chains that they link. In this way the polymer conducts from molecule to molecule and in principle may be isotropically conductive. Preferably, the polymer chains are selected from polyaniline, polypyrrole, polythiophene, poly-p-phenylene, poly-(p-phenylene sulfide) and poly-N-vinylcarbazole. The resonant groups may comprise carbocyclic or heterocyclic aromatic groups or pi -bonded aliphatic groups; p-phenylene groups and p-phenylene-vinylene groups are preferred. Such polymers can be made by a conjugative condensation reaction catalysed by a palladium compound. Three such condensation reactions are established and are named according to their respective authors as the Suzuki, Stille, and Heck reactions; the Suzuki reaction is preferred.

摘要： A structural joint for piles, columns and like structural members comprises first and second end-fittings for the respective structural members to be joined. The first end-fitting has a central socket (10) and a second end-fitting a central spigot (5) for entry into the said socket (10), and the socket (10) and the spigot (5) have mutually engaging cantilevered lugs (7), those on the spigot (5) projecting radially outwards and those on the socket (10) radially inwards. The lugs (7) are so spaced around the periphery of the joint that in one relative rotational position of the end-fittings the lugs (7) are disengaged and the end-fittings are freely separable in an axial direction and in another relative radial position of the end-fittings the lugs (7) are engaged in pairs to prevent any substantial relative axial movement. At least some pairs (preferably all) consist of lugs (7) each of which is tapered towards its unsupported end to form mutually engaging surfaces (16, 17, 18, 19, 20) having a dimension in the direction of the axis of the joint that is at least a major part of the dimension of the lug (7) in that direction and preferably practically all of it. The mutually engaging surfaces (16, 17, 18, 19, 20) are preferably parts of a cone.

摘要： An optical network in which data signals are encoded with a wavelength corresponding to the address of the signals includes, at at least one point therein, a data routing switch (1) which comprises: (i) a wavelength comparator (3) for example a Bragg grating or a notch filter that will receive data signals and has associated therewith a characteristic wavelength so that it will send the data signal along a gate enabling line (5) or not in accordance with the relationship between the data signal encoding wavelength and the characteristic wavelength of the comparator; and (ii) a gate (7) which transmits or blocks the data signal in response to the presence or absence of the data signal in the gate enabling line. Normally the network will include a number of data routing switches having different characteristic wavelengths so that routing of the data is determined by which switch characteristic wavelength matches the data encoding wavelength. Since the wavelength comparison is a passive process, comparison and switching can be performed more rapidly than with conventional systems.

摘要： A method of manufacturing a stranded assembly of flexible elements for example an electrical or optical cable in which the lay of the elements is repeatedly reversed along the length of the assembly, comprises: (i) feeding the elements (X) into one end of a guide, the guide having an upstream region in which one internal lateral dimension thereof constrains the strands to lie in side-by-side relationship and in which an orthogonal internal lateral dimension is greater than the total width of the elements, and a downstream region in which the elements are forced into a generally cylindrical geometry; and (ii) removing the elements from the other end of the guide in the form of a stranded assembly (Y). The elements are fed into the guide at a higher speed than they are removed from the guide so that they are forced into a serpentine configuration in the guide, and in the downstream region the serpentine configuration is converted into a generally helical one in which the lay of the elements is repeatedly reversed.
