Title: Cooling electric power cables
IPC: H01B7/42
Filed: 1971-10-06
Abstract: 1368497 Electric cables SUMITOMO ELECTRIC INDUSTRIES Ltd 6 Oct 1971 [7 Oct 1970 26 Nov 1970 1 May 1971] 46564/71 Headings F4H and F4U [Also in Division H1] A section of a power cable 21 is cooled by the evaporation of a liquid refrigerant in a duct along the length of the cable. Liquid flows under gravity from a reservoir 26 through a tube 27 to a joint 23 at one end of the section, heat generated by the cable causes evaporation of this liquid, and the vapour so formed passes through a joint 22 into a tube 24, which is shorter than tube 27 and which leads back to reservoir 26 and a condenser 25. The refrigerant is preferably a wholly or partly halogenated hydrocarbon, examples of which are given. The condenser 25 and reservoir 26 may be naturally air-cooled, forced air-cooled, or water-cooled. The volume of tube 27 may be large (Fig. 6, not shown) in which case it is slightly inclined and the reservoir is omitted. In Fig. 7, (not shown), the tube 27 is surrounded by a cooling water tube (28<SP>1</SP>) and both the reservoir and condenser are omitted.  Another embodiment (Fig. 9, not shown) includes refrigerant tubes (102, 103) and a natural air-cooling unit (109) with a valve (108) which is actuated by the pressure in the reservoir (104) and opens or shuts the condenser pipe. In further modifications (Figs. 10-12, not shown) a pressure-sensitive device respectively controls a fan (111) which force-cools the cooling unit, a damper (117) which controls the natural air-cooling of the unit, and a heater (118) in the reservoir. In the embodiment of Fig. 13 (not shown), heat is introduced into a heating tube (121) in the shorter refrigerant tube (103) to increase the flow of refrigerant. To maintain the pressure in the reservoir above a predetermined valve, the embodiment of Fig. 14 (not shown), includes a tank (122) of a gas, e.g. nitrogen, which is different from the refrigerant and is not condensed under operating conditions.

Abstract: 1,207,856. Fibre-glass tubes. WERKSPOOR N.V. 12 Oct., 1967 [12 Oct., 1966], No. 46661/67. Heading F2P. A method of producing a hollow member by winding layers of glass-fibre strip 4 around a former 1 and impregnating these layers, either during or after the winding operation, with synthetic resin, particularly polyester resin, is characterized in that the strip is wound, with prestressing, around the former and chopped-up glass fibre 16 is fed into the angle between the wound body of the glass fibre strip 4 already on the former and the strip portion being fed to the former. The strip 4, fed from a roll 3, passes between rollers 6-11 in a bath containing, e.g. polyester resin, and is wound on to the former 1 with a small pitch which may be reversed for successive layers. After one layer has been wound on to the former 1 chopped-up glass fibre 16 is fed through a nozzle 17 into the angle between the strip 4 and the layer of strip already wound. Cutters 18 rotate in the nozzle which is supplied with compressed air. The strip 16 may be fed to the underside of the former 1 in which case the chopped-up fibre 16 can be scattered on to the strip. The strip may be impregnated with synthetic resin by a sprayer as it is wound.

Abstract: 1331785 Lawn mowers PHILIPS GLOIELAMPENFABRIEKEN NV 2 Oct 1970 [7 Oct 1969] 46982/70 Heading A1F A cutter-cylinder lawn-mower comprises a cutter cylinder 1 driven by wheels 2 and provided with a plurality of helical knives 5 cooperating with a ledger-blade 13 fixed at one end to a sub-frame 12. The frame 4 is pivotally connected to an adjustable holder 9 for a rear roller 10. The sub-frame 12 is pivotally mounted on pins 14 projecting from the sides of the frame 4, and the cutter cylinder rotates about stub axles 16. The sub-frame 12 and frame 4 are provided with extensions 17, 18 respectively, connected by a compression spring 19 which, in the inoperative condition, enables the ledger blade 13 to engage the path of the knives 5 without contact pressure. In operation, the cutting resistance of the grass results in a force directed tangentially to the path of the knives 5 which causes the subframe 12 to tend to revolve anticlockwise about 14, thereby increasing the contact pressure. The value of this increased pressure depends on the material to be cut and the constructional features of the mower. The knives 5 are arranged so that no two knives are in contact with the cutting edge of the ledger blade at the same time. To maintain continuous contact between the knives 5 and the ledger blade 13, the side of the ledger blade which is first to come into contact with the next knife 5 is provided with a guide member 21, which may be integral with the ledgerblade. The cutter cylinder 1 may be motordriven.

Abstract: 1,079,590. Moulding porous blocks. E. I. DU PONT DE NEMOURS & CO. Nov. 9, 1965 [Nov. 10, 1964], No. 47446/65. Heading B5A. [Also in Division D1] In a process of moulding a porous, bonded fibrous block, parallel rows of fibrous elements 10 are packed into a mould 22 and adjacent rows are arranged in staggered relationship, the body of elements is then compressed along an axis perpendicular to the parallel rows at a compression ratio of 2 to 8 and to a final density of from 0À2 to 5 pounds per cubic foot. When the final density lies between 0À5 and 5 pounds per cubic foot an additional compression is applied to the body at rightangles to the first compression, i.e. transverse the rows, the combined compression ratio lying between 3À5 to 8. A set of conveyers 16, 18 extending across the mould guides one row of vertical fibrous elements at a time into the mould space, via a roll 12, and when a desired length of element has advanced into the space, the row is cut by an assembly 20. The latter includes an angle iron (30), Fig. 3, not shown, and cutter (32) and a member (34) with combs (36). The mould may have a corrugated bottom to prevent the elements slipping and devices to retain them upright during their packing. After compressing the elements into a block the filled mould may be immersed in a resinous binder and then drained and heated in an oven to cure or solidify the binder which may be thermosetting or thermoplastic. Each element may comprise a sliver of crimped fibres which may be of thermosetting or thermoplastic synthetic resins, of which many examples are given. Composite fibres or filaments may be used in the slivers, e.g. a sheath of polyamide around a polyester core. Blends of two or more fibres including natural fibres such as cotton, wool &c. may be used in the slivers; the latter may be identical or have different colours, weights &c. A thermosetting or thermoplastic binder, of which many examples are given, may be applied to the fibres, e.g. by dipping, spraying &c., before they are fed to the mould. Alternatively, for binding the fibres together, fibre solvents or high frequency heating may be used. Each sliver may be rolled from a web of fibre, and sheet material obtained from the porous block by cutting the block perpendicularly to the lengths of the fibres.
