Title: Improvements in or relating to the recovery of benzole and naphthalene from the crude gas produced and/or treated in coke oven and/or gas works by-product recovery plants
Inventor: MALOY JOHN
IPC: C07C7/00
Filed: 1958-04-28
Abstract: <PICT:0894203/III/1> Benzole and naphthalene are stripped from wash oils or oils that have been used for recovering such hydrocarbons from crude coal gas by reusing steam which has been used in one stage of the process for stripping naphthalene from the wash oil, in its naphthalene-bearing condition, for stripping benzole, or benzole and further naphthalene, from the wash oil.  In a preferred embodiment crude coal gas from a coke oven 1 passes to a flushing tank 4 and to primary coolers 5 where tar and other liquors are removed via a line 6.  The gas passes by means of a line 7 to a benzole scrubber 8 in which the gas is washed with oil primarily to remove benzole, the gas passing to a gas holder through a pipe 11.  A branch pipe 12 leads to a naphthalene washer 14 where the gas from the benzole is further washed with oil to remove remaining naphthalene from the gas in order to bring its naphthalene content down to a low level such as to render the gas acceptable for use as town gas.  Stills 16 and 17 are provided to strip the wash oil of benzole and naphthalene respectively.  The benzole-stripped wash oil for use in the benzole scrubbers leaves the still 16 by a pipe 8 and the benzole bearing wash oil leaves the bottom of the scrubber through a pipe 19 and a heater 20 from whence it is recycled to the top of still 16.  To strip naphthalene from naphthalene bearing wash oil the latter is blown with fresh open steam through pipe 24, the naphthalene bearing steam leaving the top of the still through pipes 26 and 27 to the bottom of still 16.  The benzole-and naphthalene -bearing steam leaves via a pipe 30 and is separated and the benzole recovered.

Title: Process for the manufacture of polybasic aromatic carboxylic acids
IPC: C07C51/275
Filed: 1953-05-15
Abstract: Polybasic aromatic carboxylic acids are manufactured, by condensing in known manner benzene or one of its homologues with ethylene chloride in the presence of a Friedel-Craft's catalyst to give a product of high molecular weight, and oxidizing this product to give polybasic carboxylic acids.  Aluminium chloride may be used as catalyst, and the chain length of the compounds, in which benzene rings are linked by -CH2-CH2- groups, is dependent on the molecular ratio ethylene chloride: benzene. The chain length increases as the ratio approaches 1, but it is kept below 1 for the production of dicarboxylic acids, and at such a figure that products with an average molecular weight of at least 800 are obtained.  The temperature of the reaction is adjusted to give a steady evolution of hydrogen chloride.  The reaction product may be oxidized in three ways: (1) with air at 100-150 DEG  C. in the presence of a heavy metal catalyst, (2) boiling nitric acid plus vanadic acid as catalyst, (3) bichromate-sulphuric acid mixture at 100-150 DEG  C. The acids in the oxidation product can be separated by fractional crystallization, or distillation of esters.  Besides minor amounts of benzoic acid, terephthalic and isophthalic acids are obtained. If toluene is used, oxidation of the condensation product yields tricarboxylic acids.  A slight excess of ethylene chloride leads to cross-linking between the chains, and to more tricarboxylic acids on oxidation.  Further reaction of this condensation product with toluene before oxidation, reduces the formation of benzoic acid and increases the yield of dicarboxylic acids.  In examples (1) benzene is condensed with ethylene chloride and a mixture of iso- and terephthalic acids obtained after oxidation with nitric acid, (2) the condensation product from (1) is oxidized with oxygen using cobalt nitrate and copper nitrate as catalysts.

Title: Improvements in or relating to tank cleaning devices
IPC: F28G3/16
Filed: 1959-04-22
Abstract: 853,701. Cleaning tanks. KENNEDY, M. T. April 22, 1959 [May 14, 1958], No. 13739/59. Class 138(1). [Also in Group XXIX] In a tank cleaning device comprising a rotatable turret 10 supporting a nozzle unit for rotation about an axis B at right angles to that A about which the turret rotates and a liquid conduit for supplying cleaning liquid to the nozzle unit for projection as a high-velocity jet or jets, the nozzle unit consists of one or more nozzles 11 so arranged that the reaction of the liquid jet or jets causes rotation thereof about its own axis B, a driving connection being provided between the nozzle unit and the turret 10 whereby the turret is also rotated by the jet reaction, also braking means comprising a brake member in contact with an enclosed body of braking liquid, relative rotation of the brake member and the braking liquid being caused by rotation of the nozzle unit. The liquid enters the sleeve 17 parallel to the axis A and is diverted through the openings 18 by the end wall 27 of conical shape tapering with concave curvature to a central pointed end. A shaft 55 threaded on to the end wall 56 of the nozzle carrier 43 is connected to a worm 57 meshing with a worm wheel 58 fixed to the liquid distributing sleeve 17 so as to provide the drive connection between the nozzles 11 and the turret 10. As the nozzles 11 make one revolution about the axis B, the worm 57 will make a corresponding revolution and will, therefore, move along the worm wheel 58 the distance equal to one, two, three or four teeth according to whether the worm is a single, double. triple or quadruple thread gear. Therefore, each nozzle 11 will generate a number of successive jet impingement stripes on the tank walls corresponding to the number of teeth on the worm wheel 58, starting from one wall section and returning to the same wall section for each turn of the turret 10 about its axis A. The above-mentioned braking means comprises the worm 57 forming an integral part of a drum 65 which is an integral axial continuation of the nozzle shaft 55 so as to rotate therewith and contains a viscous liquid immersed in which is a brake member 72 shown, Fig. 2, in the form of a worm. This member 72 is connected at its lower end to the turret 10. The angularity of the nozzles 11 may be adjusted for controlling the reaction effect of the cleaning liquid by supporting on the axle 86 of the nozzle carrier 43 a bevel gear which meshes with the bevel gears 85 on the inlet legs 46 of the nozzles.

Title: A method of and an apparatus for growing crystals in a vessel of vitreous material
IPC: H01L21/00
Filed: 1960-04-20
Abstract: In a process for growing a single crystal by melting and then cooling material in a closed quartz or other vitreous vessel, where the vapour pressure of the material (e.g. the semiconducting phosphors zinc sulphide, cadmium sulphide and <PICT:0923241/III/1> zinc selenide) when molten would burst the vessel which is soft at the melting point of the crystal-forming material, the vessel is enclosed in a close-fitting crucible of refractory material, the crucible and vessel are heated initially at a rapid rate so that the vessel is raised above its softening point before the crystal-forming material develops substantial vapour pressure, and heating is continued to melt the enclosed material.  The material 1 is placed in a quartz tube 2 which is evacuated, sealed and inserted in a graphite crucible 4, space between the tube 2 and crucible 4 being filled with graphite powder.  The crucible is then placed in a carbon tube having thick-walled ends 8 and a thin-walled central portion 9.  Electric current is passed through the carbon tube to heat it and soften the quartz tube 2, which then expands until stopped by the graphite crucible 4.  Further heat is applied until the material 1 is molten, and then the temperature is gradually reduced to allow the melt to solidify to form the crystal.

Filed: 1966-03-29
Abstract: 1,139,464. Inorganic chlorides. CIBA Ltd. 29 March, 1966 [22 May, 1965], No. 13916/66. Heading C1A. Chlorides of V, Mo, W, Ta, Nb, Ti and B are formed by chlorination of ferro-alloys, carbides or hard metal scrap by introducing this mixed with NaCl into a liquid melt of NaCl and FeCl 3 . at 155-700 C., removing the resulting chloride vapour and condensing it. The alloy particle size is 1 to 5 mm. and NaCl is added to the FeCl 3  to form the melt in excess of about 10% over the theoretical quantity. The ferro-alloys may have been produced by aluminium-treated ores. If the process is continuous, Cl 2  is introduced into the melt to rechlorinate the FeCl 2  formed. The process is useful for the manufacture of niobium pentachloride and tantalum pentachloride from the corresponding ferro-alloys and for the recovery of W, Ti Nb and Ta from scrap metal. The iron from the alloy is transformed to iron chloride which forms a complex with the sodium chloride, FeNaCl 4 , which complex is not volatile and remains in the melt.
