Title: Improvements in processes and apparatus for the wet treatment of coal
Inventor: FOUCAULT PIERRE
IPC: B03B9/00
Filed: 1960-08-11
Abstract: 957,724. Separating coal particles. SOC. DE PRODUITS CHIMIQUES D'AUBY. Aug. 11, 1960 [Aug. 11, 1959], No. 27820/60. Heading B2H. Coal particles are separated from "deads" or schists by flocculating in an aqueous medium moist particles derived from a previous washing operation, if desired with an addition of particles emanating from a dust removal step preceding the washing operation, filtering the flocculated particles and subjecting them to flotation, the flocculation and flotation steps being effected in the presence of a single surface-active agent which comprises (a) one or more polyalkylene polyamines of the formula: (where R denotes a saturated or unsaturated straight- or branched-chain hydrocarbon group with 8 to 22 carbon atoms, n is from 2 to 8 and p is from 2 to 6), and (b) an oily mixture of aromatic hydrocarbons corresponding in composition to the dephenolated coal tar fraction of boiling points ranging from that of naphthalene to that of anthracene ; preferably R corresponds to the acyl groups of acids existing as glycerides in natural oils and fats or fractions of such acids. The surface-active agent may additionally be employed as a separating adjuvant during water extraction of "fines" collected after the initial washing, as adjuvants in filtration or flocculation of schists and "extra-fines", and/or as a coating agent during the production of briquettes from"extrafines". The process is illustrated by Fig. 1 which shows a circuit installation with a coal crushing and screening unit 1 with a duct 2 for the discharge of dust, washing units 3-for the "fines"-and 6-for the coarser particles-each with ducts 5 and 7 respectively for the discharge of washing water into a flocculation and filtration unit 11 ; a duct 12 enables moist dust to be also discharged into unit 11 if desired. The washed "fines" (grain size less than 10 mm.) lead to a water extractor unit 8, e.g. a centrifugal hydroextractor, to be freed from water prior to passing to a separator unit 22, which sorts the "fines" into the coarsest elements (2 to 10 mm.), for discharge via duct 24 to a coking installation or steam boiler furnace, and the "extra fines" (less than 2 mm.) for discharge to a briquetting unit 21. The flocculated sludge from unit 11 passes to a flotation unit 15 from which "extra-fines" and schists are discharged into filtration units 18 and 19 respectively. The filtered "extra-fines" are passed to the briquetting unit 21 whilst the filtered schists are fed to a separator unit 26 which separates the finest (less than 0.5 mm.) from the coarsest, the liquid effluents from the filtration units passing back to the washing units 3 and 6. A reservoir 30 containing the single surfaceactive agent as above is provided to supply both the flocculation and filtration unit 11 (duct 31) and the flotation unit 15 (duct 32) and if necessary other units (ducts 33 to 36) as shown. Specifications 953,550 and 957,723 are referred to.

Title: Improvements relating to apparatus for the manufacture of artificial silk and the like
IPC: D01D1/09
Filed: 1924-11-20
Abstract: 248,046. Lunge, E., and Courtaulds, Ltd. Nov. 20, 1924. Pumps for viscous liquids; regulating delivery by by-passes or return circuits; pipes.-In apparatus for the manufacture of artificial silk, in which a viscose solution is delivered from a number of outlets 38 to spinning nozzles, conduits 16, 17 being connected at both ends to form a closed circuit from which all the outlets are supplied through similar branches, the solution is continuously circulated around the ring at a speed higher than that produced by the rate of flow from the outlets. As shown, the apparatus comprises a series of cam-actuated pumps as described in Specification 248,038 arranged end to end, the conduits 16, 17 being formed by straight bores extending through each pump body and aligned with the bores of adjacent pumps. The conduits are connected at one end by a vertical passage in which is a rotary screw for circulating the fluid, and at the other end by a vertical passage with a four-way cock for connecting either conduit to the atmosphere to enable air to be expelled at starting. Each pump has cam-actuated plungers 32, 33, Fig. 3, and a cam-actuated piston valve 34, fluid being admitted from the conduit 16 through a port 31 and expelled through a port 35 and port 37 in a valve 36 to the outlet 38. If it is desired to disconnect any pump from its outlet 38, the corresponding valve 36 is moved axially to connect the port 35 through a port 39 with the return-conduit 17. The temperature of the viscose solution may be controlled as described in Specification 248,043. Specifications 141,095, 248,039 and 248,040 also are referred to.
Patent GB-795688-A (GB)
Title: Improvements in the thermal cracking of combustible organic liquids
IPC: C01B3/36
Filed: 1955-09-30
Abstract: Combustible organic liquids are thermally cracked by burning oxygen or an oxygen-containing gas, in an amount insufficient for complete combustion, below the surface of the liquid.  The liquids to which the process may be applied include hydrocarbons, ethers, alcohols and ketones and is particularly suitable for converting mineral oils into acetylene, olefines, lower alkanes, carbon monoxide and hydrogen. Reduced or increased pressures may be used.  Ignition may be accomplished by heating the liquid and/or the oxygen so that spontaneous ignition occurs; if the ignition point is above the boiling point of the liquid, pressure may be applied.  Heating of the oxygen may be effected by burning a combustible gas such as hydrogen in the oxygen.  Alternatively a flame may be introduced in a protective bell, for example a flame of hydrogen burning in an excess of oxygen, the excess oxygen then being used as the oxygen-containing gas.  In the case of substances difficult to ignite, a heat-storage material may be arranged in the gas chamber of the combustion zone to store heat and thus ensure ignition.  Substances which reduce the ignition point may also be added to the liquid, such as ethers, ethyl nitrite, amyl nitrite and methyl ethyl ketone peroxide in the case of mineral oils.  Electrical ignition can be used, either discharge or resistance heaters being used.  Strong oxidizing agents may be added to the oxygen such as ozone, nitric acid vapour, nitrogen oxides, chloric acid, perchloric acid, chlorine dioxide, manganese heptoxide, nitrates, chlorates and perchlorates, solids and liquids being added as dust or aerosol respectively.  Oxidizing catalysts such as platinized asbestos or other platinum catalyst, magnesium silicates or aluminium silicates such as pumice stone can also be suspended in the liquid.  The oxygen may be introduced as bubbles by introduction through a sieve or frit material or slots or a layer of granular material over a grate in the bottom of the vessel, or through a nozzle or bell submerged in the liquid.  Alternatively the liquid may be allowed to flow through a tube and oxygen introduced through one or more nozzles so that the oxygen flows as a separate phase or as bubbles; liquid may be recycled after purification and cooling. Where the liquid is stationary in a vessl the depth through which the oxygen passes should be sufficient to ensure that all the oxygen is "burned."  Steam or nitrogen may be added to the oxygen to moderate the combustion.  In the examples the process is applied to the cracking of diesel oil, octane, crude oil and methyl alcohol to give hydrocarbon mixtures with oxides of carbon and hydrogen.
