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.
摘要翻译：数据信号以对应于信号地址的波长进行编码的光网络在其至少一个点处包括数据路由选择开关（1），其包括：（i）波长比较器（3），例如布拉格光栅或陷波滤波器，其将接收数据信号并且与其相关联的特征波长，使得其将沿着栅极使能线（5）发送数据信号，或者根据数据信号编码波长和特性之间的关系发送数据信号比较器的波长; 以及（ii）门（7），其响应于栅极使能线中的数据信号的存在或不存在而发送或阻止数据信号。通常，网络将包括具有不同特征波长的多个数据路由交换机，使得数据的路由由哪个开关特征波长与数据编码波长匹配来确定。由于波长比较是无源过程，因此可以比传统系统更快地执行比较和切换。

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.

摘要： A method of installing an optical cable in an overhead power transmission line which comprises supporting an optical cable (1), which has an overall protective sheath of electrically insulating material, in long lengths between towers employed to support at least one electric power transmission line (2) which is on load and, after the optical cable (1) has been so installed and while the overhead electric power transmission line is on load, providing on or in the supported optical cable at least one longitudinally continuous path (11) which extends throughout substantially the whole length of the supported optical cable and which is sufficiently electrically conductive to carry along the cable (1) any currents that may be capacitively induced. The method enables a cable that will not be subject to dry-band arcing to be installed without danger to personnel during installation.

摘要： A proces (and plant) for copper wire manufacture in which at least one copper rod with a diameter less than 3 mm is prepared by continuous up-casting and is in-line drawn through a plurality of drawing dies to form the required wire. Additional steps such as preliminary rolling, tinning, annealing, enamelling or extrusion-coating may be added to the in-line operation. The combination of up-casting and the small cast diameter makes in-line operation feasible and the elimination of protective coatings and their subsequent removal, together with the elimination of a separate "rod breakdown" operation, gives environmental and cost advantages.

摘要： A composition of matter for use as dielectric shield in an electric power cable having insulation of XLPE, EPR or EPDM comprises: a base polymer which is a copolymer of ethylene with a mono-unsaturated ester; conductive carbon black in an amount to give the composition an electrical resistivity below 500 Am; and as an adhesion-adjusting additive, 1-20 % by weight of the base polymer of a copolymer which consists essentially of ethylene and a comonomer having in its molecule at least one carbon-oxygen dipole, said copolymer having a molecular weight less than 20,000 Daltons but a melting point higher than 30 DEG C. This new class of additive permits use of EVA's with lower vinyl acetate content than prior art additives and so enables the composition to have less rubbery physical properties.
