Title: Improvements in or relating to pressure wave transmitters and receivers incorporating magneto-strictive devices
IPC: B06B1/08
Filed: 1932-06-10
Abstract: 402,828. Subaqueous audible signalling - apparatus. MARCONI INTERNATIONAL MARINE COMMUNICATION CO.,Ltd., Marconi House, Strand, and HINTON, N. P., 57, Broughton Avenue, Finchley, both in London. June 10, 1932, No. 16472. [Class 118 (ii).] A magnetostrictive pressure wave transmitter suitable for use in echo-sounding, and subaqueous signalling systems, and for detecting underwater bodies, such as icebergs, comprises a magnetostrictive body which is so chosen, proportioned and suspended that its natural period of vibration is a harmonic, and preferably the second harmonic, of the energizing frequency. Fig. 1 shows a magnetostrictive body M suspended by rollers or resilient rubber supporting members R at points one quarter of the length of the body from each end thereof. The natural mode of longitudinal vibration of the body is indicated diagrammatically by the curve c, the body being one wave length long. The energizing frequency is made one half of the frequency corresponding to this wave length. The body M may be surrounded by separate transmitting and receiving coils L1, L2 respectively, Fig. 2, the coil L1 being tuned by the condenser C1 to the energizing frequency whilst the coil L2 is tuned to twice this frequency i.e. the frequency of vibration, by the condenser C2. The tuned circuit L2, C2 is connected between grid and cathode of an amplifying valve V, the voltage applied to this valve being limited by a pair of oppositely connected diodes D, D. A series resistance R serves to prevent short circuiting of the tuned circuit L2, 02 on transmission. If desired, the diodes can be replaced by a small spark gap, a glow discharge lamp or equivalent device. Fig. 3 shows a modification in which a single winding L is utilised both for transmitting and receiving, the winding being connected in a series loop circuit with two condensers C <1>1, and C<1>2, the latter of which is shunted by a spark gap G. In this arrangement, the energizing frequency is determined by the circuit comprising the winding L, condenser C <1>1 and spark gap G which is broken down by the relatively powerful energizing impulses. The voltages set up when receiving, however, are relatively small and are quite insufficient to break down the spark gap. The frequency to which the winding is tuned for reception is therefore determined by the two condensers C<1>1 and C<1>2 in series. According to a further arrangement, a separate transmitter and receiver are employed, the receiver being tuned both as regards the dimensioning and method of suspension of the body and as regards the electrical circuit thereof to the harmonic frequency. The return magnetic path for the alternating and polarizing fluxes, as also the energizing and /or receiving coils, may be arranged in a manner generally similar to that described in Specification 402,123. Specifications 283,116, [Class 118 (ii), Signals], and 402,829 also are referred to.
Patent GB-576969-A (GB)
Title: Improvements relating to the purification of saline liquids
IPC: B01J39/00
Filed: 1941-12-22
Abstract: 576,969. Purifying liquids; filtering media. PERMUTIT CO., Ltd., PEMBERTON, R. T., and HOLMES, E. L. Dec. 22, 1941, Nos. 16516/41, 16580/41 and 1627/42. [Classes 46 and 111] [Also in Group III] Saline liquids, particularly sea water, are agitated, preferably by shaking, with a silver base-exchanger to remove chlorine ions and other anions which form insoluble salts with the silver that is exchanged. Anions giving rise to insoluble silver salts may also be removed by including other materials which will form insoluble salts with, or absorb, the anions, e.g., sulphate ions may also be removed by including a barium compound, such as barium chloride or a barium base-exchanger, or by using a silver and barium base-exchanger. The latter may be prepared by treating a silver base-exchanger with a limited quantity of a barium salt solution so that about one-fourth of the silver is exchanged for barium. In the treatment of urine, any phosphate ions are removed by the silver material and urea and other organic constituents by means of activated carbon, the liquid being subsequently passed through a bed of mixed cation- and anion-exchangers, as described in Specification 553,233, to remove nitrates or other soluble silver salts. Substances having basic reactions may also be removed by including a hydrogen-ion exchanger. The latter may be constituted by an organic silver base-exchanger having mobile hydrogen ions but, preferably, a separate hydrogen-ion exchanger is mixed with the other materials and compressed into pellets or tablets which are disrupted by the swelling of the hydrogenion exchanger on coming into contact with water. The cation-exchangers may be organic, e.g., formed by treating sulphonated coal or resins, but are, preferably, silver or barium aluminium silicates, dehydrated as described in Specification 576,971. A low silicate content improves the exchange capacity of the silver material and a higher content than that of the barium material and the exchange capacity decreases with increasing particle size. The treated liquid is preferably filtered through a filter paper or pad, which may be composed of cellulosic fibres reinforced with asbestos fibres. If activated carbon be incorporated in the filter, it is unnecessary to use a bed of mixed exchangers. A filter aid, e.g., finelydivided activated carbon, may be added to the mixture. The treatment may be effected in a container as described in Specification 576,970. Specification 402,953 also is referred to. The first Provisional Specification describes also the use of aluminium compounds, e.g., activated alumina, for removing phosphate ions.

Patent GB-355832-A (GB)
Title: Improvements in the collection of sulphur
IPC: C01B17/02
Filed: 1930-05-31
Abstract: The separation of elementary sulphur from containing gases, resulting, for example, from the reduction of sulphur dioxide by coke at a high temperature, in which the content of sulphur vapour is low, is effected by subjecting the mist or fume produced by cooling the gases to an ageing period at temperatures lying between 100 DEG  C. and the condensation temperature, whereby the size of the condensation particles is increased and separation by condensation on a cold surface or by other means is rendered possible.  Uniform results and larger condensation particles are obtained by regulating the amount of dust, either removing all but the desired amount or, preferably, by removing the whole and adding so much, for example 5 per cent, of the raw gases as will furnish the desired amount of dust.  In ageing the gases, the rate of cooling is slow and varies from 0,-25 DEG  C. per second, preferably 5-10 DEG C. per second. The cooling may be performed in stages by passing the gases through a series of vessels maintained at a uniform temperature within the range at which ageing takes place.  Alternatively, the cooling may be continuous by passing the gases through a chamber lagged to maintain the desired temperature range; the cooling chamber may be in the form of a waste heat boiler.  In a modification, a fume of sulphur produced by rapidly cooling to a low temperature is rendered more easily separable by heating to a temperature below that at which the fume vaporizes and maintaining it at that temperature for the requisite period; alternatively the fume may be revaporized, condensed and aged.  An example is furnished giving details of the treatment of a gas of definite composition.

Filed: 1924-07-16
Abstract: 241,276. Chemical Engineering Co. (Manchester), Ltd., Spensley, J. W., and Battersby, J. W. July 16, 1924. Fats and fatty oils, extracting.-Oil is extracted from blubber or other oil-bearing tissues of marine animals by cutting the blubber into strips of a size of about 6in. by 3in. by 1in. These strips are passed into the hopper h of a high-speed pinned disc mill d such as that described in Specification 186,462, [Class 59, Grinding, crushing, &c.], in which the fibres are disentangled. The mill preferably has discs about 26in. in diameter and is rotated at about 3,000 revolutions per minute; a casing b round its discharge outlet is surrounded by a steam coil n. The discharged product may be supported on wire netting to permit a substantial part of the total weight of the whale oil to drain off. The fibres are then subjected to pressure under a hydraulic press or by passing through rollers, or are heated in an ordinary centrifugal separator to remove the greater part of the remainder of the oil. The oil which has been separated is warmed to about 110‹ F. to cause the small amount of disintegrated fibre still present to rise to the surface, after which the pure oil is run off from below. The fibres are passed through the ordinary process of liming, washing, steaming, or boiling for the extraction of gelatine, followed by purification of the weak liquors, the impurities being taken down by precipitating the excess lime with phosphoric acid. The process is completed by filtering, evaporating, casting, and drying. In one Provisional Specification the application of the process to the extraction of oil from cods' livers, the extraction of seal oil, herring oil, and Japanese fish oil is also described.
