摘要： 398,206. Coil-loaded submarine cables. STANDARD TELEPHONES & CABLES, Ltd., RILEY, T. N., HUGHES, R. L., and COLE, R. A. L., Connaught House, Aldwych, London. March 8, 1932, No. 6963. [Classes 36 and 37.] The coil boxes of a coil-loaded submarine. cable are formed with a diameter equal to that of the cable core, so that the lead sheath and armouring of the cable may extend continuously over the coil boxes. The boxes, which are preferably formed with two flat sides to allow room for the passage of the coil leads, may be connected together in chain form by spring links, rubber spacers through which the connecting links pass being disposed between adjacent boxes. The end boxes of the chain are secured to the cable by connection to a plurality of insulated wires which are laid up round the centre component of the cable and extend throughout the entire length thereof or, at least, for a sufficient distance to get an adequate friction grip. The coil boxes, which may be of metal and coated with hard rubber, are preferably shaped, as shown in Fig. 1, being adapted to fit within the cable sheath with their longer dimension along the cable axis and are formed in halves b secured together by bolting. A cavity 6 is formed in .each half to accommodate the loading coil which is secured therein with its axis perpendicular to the flat sides 12 of the box by rubber bushes inserted in' apertures 1 which are formed in the sides 12 and through which the coil leads pass. The contacting faces of the halves are formed with recesses 3 to receive the ends of the spring connecting-links which are retained therein by bolts passed through holes 4. These bolts also secure the two halves of the box together. In order that the chain of boxes may be uniformly rigid in all directions, consecutive boxes may be given a twist around the cable axis so as to lie in helical form. The direction of the helix may reverse at intervals. Fig. 4 shows boxes 7, 8, 9 arranged helically within a sheath 13 and spaced by skewed rubber blocks 10, 11. The boxes are connected together by spring links 14. The squads of the cable are connected to the coil by small-gauge textile- or paper-insulated wires which are laid up in groups in the helical space between the coil boxes and the cable sheath. The whole joint is then padded out to the cable diameter, dried, and sheathed together with the attached cable lengths. The unloaded lengths are also dried and sheathed and jointed to the loaded lengths, the whole then being stripped and lead-sheathed in a continuous length.

摘要： 339,990. Standard Telephones & Cables, Ltd., Scott, T. R., and Riley, T. N. Sept. 18, 1929. Drawings to Specification. Condensers.-A process for the impregnation of insulating materials such as fibrous insulation with a hydrocarbon oil in the manufacture of high tension cables or electric condensers consists in drying and exhausting the insulation and, before impregnation, replacing the residual air by the vapour of a substance which vapourizes under the temperature and low pressure conditions in the impregnating vessel and which is condensed to a liquid or a solid under the tern. perat,ure and pressure conditions of service. The impregnating vessel may be the lead sheath of a cable, and, preferably, the substance is such as. to condense during impregnation. In one method, a substance is introduced which wholly maintains the normal absolute pressure of the impregnating vessel by vapour pressure, the pressure remaining constant while the limit of vacuum is being reached by the pumping, and the action is stated to be a gradual replacement of residual air in the insulation by vapour. A condenser trap is fitted to the impregnating vessel to pass air and moisture but retain condensible vapour in the vessel. The impregnating medium is admitted to the vessel and the vapour is condensed by a gradual temperature decrease or by forcing in the impregnating medium at a pressure greater than the vapour pressure of the condensible substance at the temperature of impregnation. The insulation is impregnated at a temperature of 130‹-140‹ C. and an absolute pressure of 55 mm. of mercury or less. The pressure head of the incoming impregnating compound may be sufficient to condense the vapour without temperature change, the Specification stating that when a cable is impregnated at 5 mm. pressure and 108‹ C. with diphenyl as the vapourized substance, an oil head of three inches at the surface of the incoming compound is sufficient to condense the vapour. A mixture of vapourizable materials may be used such that the sum of the partial pressures at any temperature gives the desired pressure. The substance may be vapourized in a separate system and introduced as a vapour to the impregnating vessel or may be introduced as a solid or liquid and evaporated. The substance may be sprayed in at reduced temperature as a liquid into the fibrous insulation so that evaporation may occur in the interior of the insulation when the temperature is raised. The substance may be incorporated in a cable during manufacture and evaporated during or after the final drying operations. The substance may be applied to the cable core, and is preferably such as will not evaporate during the initial stages of drying. An example given consists of a copper core which after stranding, is. passed through a bath of a substance which does not evaporate below 100‹ C. at atmospheric pressure. The core is then insulated. The whole fibrous insulation may be impregnated with the vapourizable substance before, or after, application to the cable, and varnished with a retaining medium which may be of a resinous nature. In an example, methyl naphthalene is used as a vapourizable substance, the temperature being raised towards the end of the drying by passing an electric current through the core. Materials which may be impregnated are stated to be paper, textile materials, hydrocarbon oil with or without resins, tars, bitumens, resins and synthetic resins in solvents, cellulose acetate in solvents, sulphur, waxes such as paraffin, ceresin and beeswax, halogenated waxes such as chlorinated naphthalene, and petroleum jellies. Methyl naphthalene and diphenyl, when used as the vapourizable substance, are stated to reduce the dielectric losses of the oil in the finished cable. Diphenyl, methyl naphthalene, and aromatic hydrocarbons may be used as vapourizable materials in order to increase the resistance of the impregnating compound to deterioration. A vapourizable substance may be used which, on condensation, improves the absorption properties of the fibrous material, e.g. by wetting the surface of the fibres, or a substance may be used which forms a protective film on the fibres provided that the film is chemically inactive under electric discharge in the cable. For condensers, a vapourizable material of high specific inductive capacity such as glycol or ethylene glycol may be used. These substances are stated to raise the specific inductive capacity of the impregnating material. The vapourizale material may be an introfier for the impregnating material. It is stated that, for introfying sulphur into fibre boards or asbestos at 135‹ C., naphthalene, diphenyl, and triphenyl are vapourizable substances to be used.

摘要： 291,871. Standard Telephones & Cables, Ltd., Riley, T. N., and Scott, T. R. March 9, 1927. Cables, arrangement of parts of.-A single-core cable comprises a conducting core A surrounded by a layer B of impregnated fibrous dielectric, a second layer of porous or semi-porous material D, and a metal sheath E. A permeable intersheath C of metallized paper separates the dielectric from the porous material D, and the layer D is made of material which is preferably much less absorbent than the material B. When the cable is in use and the dielectric expands, some of the impregnating fluid may pass through the intersheath C and may be taken up by the material D. Should a contraction take place, the fluid will be drawn back by the more absorbent material B, so that the homogeneity of the dielectric is maintained. The intersheath C and the outer sheath E are connected together.

摘要： 275,721. Standard Telephones & Cables, Ltd., and Riley, T. N. May 11, 1926. Cables and conductors, processes for making.- In the manufacture of electric cables in which the conductors are surrounded by a fibrous dielectric, such as paper, impregnated with a suitable oil or other compound, and the cable is subjected to two successive treatments, e.g., drying and impregnation, the duration of the first treatment is determined by maintaining the A.C leakance under observation by an indicating instrument, until it becomes substantially constant below a predetermined value, the other treatment being then started. The duration of the impregnation treatment is determined by the observed A.C. capacity remaining constant above a predetermined value, and the subsequent necessary treatment such as cooling is then begun. The apparatus used in making the observations is preferably the A.C bridge described in Specification 267,307, [Class 37, Electricity, Measuring &c.].

摘要： 258,342. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), Nash, G. H., and Riley, T. N. June 17, 1925. Cables, processes for making.-In a method of impregnating the insulation of stranded cables, air or moisture is withdrawn from ,the cable in a direction transverse to the direction of penetration of the impregnating compound. The cable mounted on a drum 4 may be immersed in a tank 1, Fig. 1, containing the impregnating material and a vacuum applied to the upper part of the tank. Alternatively, the exhaust pipe 6, Fig. 2, terminates in two caps 7 tightly fitting over the cable ends and pressure is supplied through the pipe 8. In a further modification the impregnating composition is forced through the pipe 6 and the pipe 8 connected to the exhaust.
