Title: Process for recovering finely divided solids from aerosols
Inventor: WILSON CHARLES LOUIS
IPC: C09C1/48
Filed: 1954-08-07
Abstract: <PICT:0759655/III/1> Finely divided solids, such as carbon black or metallic oxides, are separated from an aerosol by passing the aerosol through cyclone separators in series, the separators being arranged so that part of the separated solids are returned to the inlet of the first cyclone of the series.  Carbon black generated in a reactor 10 passes through a cooler 12 to the inlet of the first cyclone 14. Partly cleaned aerosol from the cyclone 14 is passed through the cyclone 16.  Partly cleaned aerosol from the cyclone 16 passes to a filter 18 discharging gas to the atmosphere.  Preferably four cyclones constitute the series and from one or more of the cyclones, preferably the last, a minor proportion of the aerosol is withdrawn through a pipe 26 to which is supplied solids recovered from the filter.  The pipe 26 has a fan 28 and discharges into the inlet of the first cyclone.  Solids are discharged from the cyclones to a gas line 32 which leads to cyclones 36, 38 and a filter 40 placed in series.  The solids discharged from the cyclones 36, 38 and the filter 40 are collected in a conduit 46.

Patent GB-1302632-A (GB)
IPC: G01S15/60
Filed: 1971-04-19
Abstract: 1302632 Doppler systems FRIED KRUPP GmbH 19 April 1971 [5 March 1970] 23164/71 Addition to 1274054 Heading H4D The Doppler system of the parent Specification 1,274,054 is modified in that to reduce undesired side-lobes in the transducer array directional characteristic a star-connected inductor arrangement is connected across the 3-phase conductors, and the inter-transducer spacing in a direction oblique to a longitudinal axis of the array is made less than #/3, where # is the sound wavelength. In the embodiment of Figs. 1 and 3, where energization of transducers 1 by phases R, S, T gives a required wavefront W1 (Fig. 1), an undesired wavefront W2 is reduced by making X2 < #/3. The star-connected device 51 (Fig. 3) forces the sum of the voltage vectors supplying the transducers to be precisely zero, thus preventing any side-lobe generation in a direction normal to the plane of the transmitting array 2. A similar device, 51<SP>1</SP>, is connected across the output lines R, S, T of receiving array 2<SP>1</SP>. An auxiliary echo-sounding device with a verticallydirected sounding beam for determining water depth comprises a transmitter 53 for intermittently injecting a pulse via transformer 54 into common point 52 of the star-connected device 51, a transformer 54<SP>1</SP> and amplifier 56 for obtaining the resulting echo pulse via common point 52<SP>1</SP> of the star-connected device 511, and a timing unit 57 started by the injected pulse and stopped by the echo pulse. The depth measurement may be used at 62 to control the duration of the signals transmitted from array 2 for the Doppler measurement, so that the signal duration increases with depth. Capacitors may be used in conjunction with the star-connected devices (Fig. 4, not shown) to provide band-pass filtering for rejecting noise frequencies.

Title: Improvements in the production of filaments, films and like shaped articles from acrylonitrile polymers
Inventor: HODGE ARTHUR
IPC: D01F6/18
Filed: 1950-09-21
Abstract: A solution of a fibre-forming acrylonitrile polymer is shaped and set by a coagulating medium comprising as the chief or sole constituent a liquid aromatic hydrocarbon or a liquid halogenated aliphatic hydrocarbon to form filaments, films and other shaped articles.  The term acrylonitrile polymer includes copolymers in which acrylonitrile is the main constituent (especially exceeding 85 per cent.) with methacrylonitrile, vinyl chloride, vinyl acetate, acrylic acid esters such as methyl and phenyl acrylate, styrene and its derivatives and vinylidene chloride.  Aromatic hydrocarbons, especially benzene, toluene, the xylenes and alkyl benzenes such as solvent naphtha are preferred as the coagulating medium.  Chlorinated paraffins such as carbon tetrachloride, ethylene dichloride and symmetrical tetrachlorethane may also be used.  If desired, a more polar liquid such as ethanol may be added to the coagulating medium in an amount up to 30 per cent. by volume or the limit of miscibility with the aromatic hydrocarbon or halogenated aliphatic hydrocarbon, whichever is the lower. The acrylonitrile polymer may be dissolved in dimethyl formamide, gamma-butyrolactone, gamma- and delta-valerolactones, propiolactone and other beta-lactones, tetramethylene sulphone and solvents comprising nitromethane with or without formic acid. Dimethyl formamide or a mixture of nitromethane and a minor proportion but at least 6 per cent. of water are preferred. Preferably the polymer has a viscosity in 1 per cent. solution in dimethyl formamide at 20 DEG C. of between 2.5 and 4 centistokes. The solution to be extruded or cast may have a concentration between 7.5 and 25 per cent. and the temperature should be high enough to maintain solution.  The temperature of the coagulating medium may be preferably between 50 and 100 DEG C.  The filaments films and other shaped articles may be stretched or relaxed by known methods.  In an example a 20 per cent. solution of polyacrylonitrile (viscosity 2.52 centistokes) in dimethyl formamide at 40 DEG C. is extruded as filaments into benzene or a 5:1 by volume benzene/ethyl alcohol mixture at 60 DEG C.  The Provisional p  Specification also refers to the following as suitable solvents for the acrylonitrile polymer: nitro ethanol, nitro propanol, and cyclic aliphatic anhydrides such as maleic anhydride, succinic anhydride and glutaric anhydride. Specification 690,553 is referred to.
