Abstract: 808,845. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO. Ltd. Nov.15, 1956 [Nov. 24, 1955], No. 33740/55. Class 35. Converting electric energy into motion of fluids by the action of magnetic fields."-A direct-current interaction pump for high pressure and small flow is provided with a spiral duct traversed by a radial flux and axial current. An annular channel 6 is formed between a central core 1 and annular poles 10 carried in a magnetic yoke 11, the central pole providing a flux return for the other two. The poles are magnetized by coils 14, 16 carrying current which enters through annular conductor 13 and leaves through a further annular conductor 17 which is inturned to make contact with an end closure ring 7 of the channel 6. The current passes axially along this channel and leaves by annular conductor 24. Fluid entering the channel at 8 is forced into a helical path by vanes 21, the middle section being of opposite hand because of the opposite polarity of the central pole. Fluid reversal is facilitated by divergence of the vanes at the ends and by baffles 23. Armature reaction compensation is achieved by passing the current under the pole-faces between magnetic inserts 18.

IPC: H04B3/14
Filed: 1958-10-24
Abstract: 875,397. Attenuation equalizers. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Oct. 24, 1958, No. 34188/58. Addition to 793,165. Class 40(8) The network of the parent Specification is modified in that the fixed inverse impedances in the series arms of the auxiliary lattice network are replaced by the filters F, F<SP>1</SP> having input impedances which are inverse with respect to the impedance R o  of the whole network. The filters are terminated in resistances R o  and are designed so that adjustment of R a , Rb produces variations only in the attenuation bands of the filter, the attenuation outside these bands being constant. The network of Fig. 3 is, apart from the filters F, F<SP>1</SP> identical to that of Fig. of the parent Specification. The networks F, F<SP>1</SP> are simple band-stop filters. The Specification which does not admit of satisfactory abridgment, gives in detail methods of calculating the elements of these filters to obtain desired input impedances. In practice several networks having different zones of correction are connected in tandem to form an equalizer effective over a wide frequency band. The modified network of Fig. 7 gives two zones of correction and comprises two parallel-connected lattice networks Q 1 , Q 2  constructed according to the invention. The output terminals of the networks Q 1 , Q 2  are connected to transformers T 1 , T 2  arranged in series in the shunt arm of the bridged-T. The network of Fig. 8 is electrically equivalent to that of Fig. 7. In this case the outputs of lattice networks Q 1 <SP>1</SP>, Q 2 <SP>1</SP> are arranged in series in the shunt arm of the bridged-T and the inputs are connected to a pair of secondary windings on a single transformer T 3 . The primary of the transformer constitutes the bridge arm of the bridged-T. The Specification describes a detailed embodiment of this modification (Fig. 9, not shown). Specification 469,067 also is referred to.

Inventor: BADGER EDWARD HENRY MICHAEL
IPC: C02F3/12
Filed: 1957-11-05
Abstract: Industrial effluents containing polyhydric phenols, especially gasworks effluents, e.g. the effluent from ammonia stills, are treated with an iron or aluminium salt, e.g. ferric chloride, chlorinated copperas, aluminium sulphate or alum, or with ferrous sulphate (in which case the effluent is subsequently aerated to form the ferric salt in situ), or with a strong mineral acid, e.g. hydrochloric acid; before or after this treatment, the effluent is subjected to a biological purification process, e.g. described in Specification 885,834.  In examples the amounts of thiocyanate and phenols in effluents and also their oxygen absorption values are compared when the treatment is applied to effluents before and after biological oxidation.  Adjustment of pH to between 6 and 8 by addition of sodium hydroxide is necessary prior to biological oxidation.  According to the Provisional Specification the treatment with an iron or aluminium salt or with a strong mineral acid need not be followed or preceded by a biological purification process.
