Abstract: 816,633. Reinforcing, laying and suspending cables. POSTMASTER GENERAL. July 5, 1957 [July 6, 1956; Aug. 14, 1956], Nos. 21088/56 and 24881/56. Class 36. The outer sheath 2 of a cable 1 is provided with one or more longitudinal grooves 3, each of which receives and grips a supporting hawser 5. The cable may be eccentric with respect to the sheath, which may be of polythene. The mouth 4 of groove 3 is narrower than the diameter of the hawser 5 so that the latter may be inserted in the grooves by distortion of the lips 6 which then restore to their original position to grip the hawser. The sheath may be formed with additional grooves or longitudinal passages 7 to reduce the weight of the cable. Strengthening wires or additional conductors may be accommodated in the passages 7. The sheath 2 may be discontinuous along the length of the cable so that the hawser is held only at intervals. The hawser may act as a messenger wire for overhead cables or as a reinforcement for submarine or underground cables, and may be forced into the groove during laying.

Abstract: 587,598. Drawers. BRITISH THOMSONHOUSTON CO., Ltd., MOIR, J., LESLIE, J. A., and LONG. A. H. Nov. 1, 1944, No. 21368. [Class 52 (i)] [Also in Group XL] A chassis or drawer mounting means such as for electrical equipment comprises a slidable carrier which is withdrawable from a rack, and a chassis pivotally and slidably mounted on the carrier. After withdrawal of the carrier the chassis may be slid and then rotated, relatively to the carrier to enable the underside of the chassis to be readily accessible. In Fig. 1 the chassis 6 is pivoted at 10 on carrier rails 5 slidable over rack 2 on rollers 7, 8. A hinged catch 11 prevents rotation of the chassis 6 whilst the carrier is being withdrawn. In order that chassis 6 may have substantially the depth of the rack 2 it has grooves 14 and 13, Fig. 2, which allows it to be slid relative to the carrier before rotation about pivots 10 which co-operate with the circular holes of grooves 14. The pivots 10 are of arcuate shape to prevent them entering the grooves 14 when the chassis is in the vertical position, and pegs 15 running in grooves 13 keep the chassis in a horizontal position whilst it is moved relative to the carrier. Further catches may be provided to prevent the carrier from being moved beyond a safe distance with respect to the rack and by operation of these catches the carrier may be completely removed from the rack.

Title: Improvements relating to methods and apparatus for hardening briquettes by coking
IPC: C10B53/08
Filed: 1957-07-05
Abstract: 842,172. Carbonizing fuel briquettes. DIDIER-WERKE A.G. July 5, 1957 [July 7, 1956], No. 21441/57. Class 55 (1). Fuel briquettes are coked by direct heating with hot gases in three zones, in the first of which the gases at a high coking temperature form a thin coked layer on the briquettes so that they retain their form when, in the second zone, under the action of somewhat cooler gases, most of the volatile matter is extracted, the third zone being supplied with gases at a high coking temperature to complete the coking process. Briquettes from hopper 9 pass through hopper 8 on to an endless belt conveyer 6. Gases supplied from a gas reservoir pipe 28 are burnt in a combustion chamber 25, mixed with more gas and supplied at a temperature of 550‹ to 600‹ C. through passage 17 and roof recess 13 to the briquettes. The gases pass through the layer of briquettes, are reversed in chamber 10, and pass again through the layer to the roof recess 14 leading through passage 18 and fan 36 to the gas reservoir pipe 28. In the second zone, gases at a temperature below 550‹ C. pass from a mixing chamber 26 through inlet 19 and roof recess 15 to pass downwardly through the layer of briquettes and then upwardly to the roof recess 14. The mixing chamber 26 may be constructed as a combustion chamber. In the third zone gas from a combustion chamber 27, mixed with gas direct from the pipe 28, passes at a temperature of 700‹ to 800‹ C. through the passage 20, roof recess 16 and layer of briquettes to the reversal chamber 12 and then through the layer again to the roof recess 15. The gases evolved from the briquettes mix with the heating gases and are partially recycled to the mixing and combustion chambers, partially sent to shaft 21, where the briquettes are cooled before passing to a coke-quenching arrangement 23, below a grid 22, and partially withdrawn from the system through pipe 45.

Title: Improvements in or relating to the preparation of bulky yarn
IPC: D02G1/16
Filed: 1956-07-12
Abstract: 814,829. Spinning and finishing yarns. DU PONT DE NEMOURS & CO., E. I. July 12, 1956 [July 13, 1955], No. 21627/56. Class 120(3) Yarn composed of continuous filaments of artificial or synthetic materials e.g. viscose rayon, cellulose acetate or a polyacrylonitrile, polyamide or polyester, is rendered "bulky" by successive treatments of coating with a water-sensitive size i.e. one which may be applied in the form of an aqueous solution or, if applied in an organic solvent is sensitive to water to the extent that when subjected to high humidity e.g. in the form of water vapour or low pressure steam, it becomes soft and "tacky", subjecting to a high velocity jet of gas e.g. air, under conditions such that the individual filaments are separated and whipped about sufficiently to form individual filament convolutions, treating (optionally, in wound package form) in a warm, humid atmosphere e.g. of at least 75 per cent relative humidity and wetbulb temperature of at least 140‹F., to render the size tacky, and drying. The convolutions are retained, without addition of twist in the yarn and even with a low residual twist e.g. to 3 turns per inch, therein, by the size, which may be removed by aqueous scouring after the yarn has been made into a fabric. The bulky yarn may be "textured" by cutting or singeing the protruding filament loops e.g. by passage of the yarn, on leaving the air jet, against an abrasive element. Examples of size are alkali metal (e.g. sodium) salts of carboxymethyl cellulose, polyvinyl alcohol compositions which may contain boric acid, starches and starch derivatives e.g. starch ethers, and waterinsoluble copolymers of vinyl and acrylicesters and polymerizable carboxylic acids such as crotonic, acrylic, or maleic acid.

Title: Process for the preparation of 1,5-and 1,8-diaminonaphthalene
IPC: C07C209/36
Filed: 1976-05-25
Abstract: These known substances are obtained by catalytic hydrogenation of the corresponding dinitronaphthalenes. While it was previously necessary to employ pure dinitro compounds because the technical-grade crude products are only hydrogenated slowly and incompletely, it is now possible to prepare them starting from crude dinitro compounds. These compounds are first treated with water or an aqueous solution with an alkaline reaction, if appropriate with addition of a solvent which is not miscible with water, such as benzene, naphthalene or halohydrocarbons, at a temperature between 0 DEG C and the boiling point of the mixture, the aqueous, or aqueous/organic, solvent phase is then separated off, and the product is subjected to conventional catalytic hydrogenation.
