Title: Crimped cellulose yarn and process of making same
IPC: D02G1/12
Filed: 1962-04-09
Abstract: 973,663. Finishing and testing yarns. J. BANCROFT & SONS CO. April 9, 1962 [April 24, 1961], No. 13581/62. Heading D1F. Regenerated cellulose multifilament yarn is crimped by feeding it into a closed crimping chamber against the pressure of a compacted mass of already crimped yarn therewithin so that the incoming yarn becomes crimped and advances along the chamber to a point where it is discharged in the form of a compact core having a crosssection corresponding to that of the chamber. The crimp is permanently set by winding the core in successive convolutions on to a previous support to form a core package which is treated in a closed chamber e.g. a dyeing vat or an autoclave, with heat and moisture under pressure and for a related time e.g. with steam at 20-100 p.s.i.g.for 5 minutes to 2 hours (varying inversely therewith) which may be preceded by circulation of hot or cold water through the package. The package is dried and the yarn rewound from the core package under tension sufficient to straighten the crimps. Crimp effects are allowed to develop by release of tension during knitting or weaving, and/or a fabric may be treated e.g. by washing in water followed by drying under tensionless conditions to develop and/or enhance the crimp. Crimp is tested by supporting a skein of a predetermined yarn length from a fixed support and measuring the length of the skein when loaded with a weight just sufficient to align the yarns and then with another weight which removes the crimp: the percentage change in the skein length represents "crimp level" which, in the specific examples, is more than 15. Apparatus for crimping, winding and unwinding the core package and the construction of the latter are all as described in several other Specifications e.g. Specifications 969,622, 969,624 and 969,625.

Title: Process for the separation or thickening of suspensions in coal washing plants
IPC: B03B5/32
Filed: 1939-05-09
Abstract: 528,590. Washing coal. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. May 9, 1939, No. 13897. Convention date, Dec. 28, 1938. [Class 82 (ii)] In the separation or thickening of suspensions in coal washing plants, particularly those using heavy liquids, use is made of a cyclone having a cover plate and an opening in the latter for the clarified fraction, whereby the suspension is separated into two fractions of controllable concentration. Coal and rock are separated in a tank 1 containing a loess suspension and are led by a scraper 2 and conveyer 4 respectively to sieves 3, 5 to which water is supplied by a cistern 12 ; diluted suspension from the sieves 3, 5, passes through a vibrating sieve 6, which removes coarse particles, to a tank 7 and is then forced by a pump 8 to cyclones 9 from which thickened suspension passes by a tank 10 to the tank 1, and clarified water passes to the tank 12 or by an overflow to cyclones 11 from which the heavier fraction passes to tank 7 and water passes to outlet c. The concentration of the two fractions may be controlled by suitable choice of the diameters of the outlet openings or adjusting the supply pressure or both ; further foam flotation methods may be applied in the cyclones. The process may be applied to the preparation of suspensions from normally unsuitable material such as a mixture of sand and clay. Specifications 455,845, 507,412 and 514,515 are referred to.

Abstract: 1,121,812. Loading and unloading ships; endless conveyers. ORENSTEIN-KOPPEL UND LUBECKER MASCHINENBAU A.G. 2 Aug., 1965, No. 13590/68. Divided out of 1,121,811. Headings B8A and B8E. A conveying apparatus mounted on a ship comprises a gantry 9, Fig. 1, movable longitudinally above the holds of the ship, a bucket elevator supported on a structure 12 carried by the gantry, the elevator including an endless bucket chain 21, Fig. 3, extending round guide pulleys 22, 23, and an endless belt conveyer 26 extending beneath a straight run of the chain extending downwardly from the pulley 22 to the pulley 23, the chain being driven so that it runs from the pulley 22 to the pulley 23 and consequently material in the buckets is delivered to the conveyer 26. The gantry 9 travels on rails 8 and has rails 10, 11 on which runs the structure 12 carrying a driver's cab 13. The structure 12 has cheeks 15 which pivotally carries at 16 a support arm 17 so that the lower part of the elevator can be turned from the position shown in Fig. 3 to a raised position (34), Fig. 2 (not shown), above the holds. The elevator is turned by a spindle and nut device or an hydraulic ram 18 connected pivotally to the structure 12 at 19 and to the arm 17. The latter has pivotally connected to it at 28 an arm 29 which carries an elevator chain guide pulley 30 and is movable by a spindle and nut device or an hydraulic ram 31 so that the guide pulley 30 can be adjusted relative to a guide pulley 20 on the arm 17, e.g. for emptying the corner spaces of the holds. The conveyer 26 discharges on to a conveyer 36 which is mounted on the gantry 9 to be retractable and/or pivotable and/or movable vertically. The broken-line retracted position of the conveyer 36 is used when it loads the holds, the material being fed to the conveyer 36 by a conveyer 40. A tensioning guide pulley similar to the pulley 30 may be carried by the structure 12. In a second embodiment, Figs. 4 and 5, the conveyer 26 is longitudinally displaceable so that it can be alternatively used for unloading and loading the ship. When in the unloading full line position the conveyer 26 discharges into a hopper 43 of a carriage 44 which is movable longitudinally of the ship and guides in a loop 46, 47, 48 the belt of a conveyer 45 extending along the ship. At the discharge end of the conveyer 45 there is a discharge device which may be a conveyer similar to the conveyer 36 and at the other end there is a feed device. The material fed to the conveyer 45 is discharged at 50 into a hopper 51 feeding the conveyer 26 when this is in the loading broken line position.

Abstract: 551,059. Protective cut-out arrangements, BRITISH THOMSON-HOUSTON CO., Ltd., TRENCHAM, H., and MORTLOCK, J. R. Oct. 30, 1941, No. 13986. [Class 38 (v)] In a protective arrangement for metal-clad switchgear (which may be insulated or not from earth) the framework 1 is connected to earth at 6 over the primary winding of a current transformer 7, the secondary of which energizes the current winding 8 of a power-directional relay so as to respond only to earth-leakage current from the framework to earth. To avoid operation by leakage in the cables, the cable-entry boxes 4 are lightly insulated from the rest of the gear and a connection 11 taken therefrom to the point A on the conductor 6 below the current transformer, so that if any current flows from 16 through the transformer 6 to the framework and thence to earth (supposing the framework to be earthed), it will be in the non- tripping direction. The polarizing winding 10 of the relay 9 may be located in, or transformerconnected to, Fig. 2 (not shown), a further earth connection. Winding 10 may alternatively be energized by the current in the neutral-earth connection of a generator or transformer supplying the gear, Fig. 3 (not shown), or from conductor 6 between the point A and earth, Fig. 4, the conductor 6 being therein divided and connected to two switchgear-sections and including two transformers 7, 7<SP>1</SP> feeding separate coils 8, 8<SP>1</SP>.

Abstract: 844,999. Magnetic chucks. HAGOU METAALWARENFABRIEKEN N. V. April 24, 1959 [April 24, 1958], No. 14057/59. Class 60. A magnetic chuck comprises upper and lower plates 16, 18 which are relatively movable from a first, work-holding, to a second, work-releasing position, at least one of the plates having a plurality of permanent magnets 28 adapted to co-operate with flux-conducting means 34 on the other plate to provide a work-holding circuit when in the first position, Fig. 2, and to neutralize the flux when in the second position and one of the plates being provided with at least one inclined cam surface 42 extending in the direction of relative movement for co-operation with a ball or roller 40 carried by the other plate so as to effect separation of the plates during relative movement of the plates from the first to the second position. The permanent magnet elements 28, 34, which may be of a partly ceramic material, are polarized in the direction generally parallel to the plane of the upper surface of the plate 16, like poles opposing those of adjacent elements. They are separated by space-bars 20, 36, of soft iron and are preferably provided with wearing-strips of non- magnetic material e.g. stainless steel. The spacer-bars are held in a frame comprising non- magnetic side and central members 22, 32, 24, 26. The two plates 16, 18 are contained within a non-magnetic housing 10 to which the upper plate 16 is attached whilst the lower plate 18 is movable within the side walls in the direction of polarization, to the extent of one pole-pitch. Springs 19 are provided to retain the plates in contact when the like poles of the elements 28, 34 are opposed. When moved towards the workreleasing position of the resulting attraction, the unlike poles is lessened by the action of the wedge-like cam members 38 riding on the followers 40. A second inclined face 44 allows the faces to contact again when a distance of one pole-pitch has been traversed by the lower plate 18. In the modification shown in Fig. 4, the direction of magnetism of the permanent magnets 62 is normal to the work contacting surface of the upper plate 50. Soft iron members 52 and 64 are separated by non-magnetic strips 54, 66, the whole being held together by draw-bolts 56, 68. The upper plate 50 is secured to a casing 58 of non-magnetic material, e.g. aluminium, whilst the lower plate 60 is allowed longitudinal freedom of movement during which cam-faces 78 engage rollers 76 to separate or close the contacting faces of the two plates. Springs, such as 19 of Fig. 2, may be used below the flux return member 70 to hold the separated lower plate from the bottom of housing 58.
