Filed: 1974-07-26
Abstract: 1446274 Actuated sludge process L1NDE AG 26 July 1974 [26 July 1973 (2)] 33094/74 Heading C1C Organically polluted aqueous liquids are treated in an aerating tank with oxygen or an oxygen-rich gas in the presence of activated sludge, a part of the mixture being continuously withdrawn from the aerating tank to a settling tank where the purified liquid is separated from the sludge, and at least a part of the separated sludge is recycled to the aerating tank; wherein at least part of the treated liquid/sludge mixture is stripped with an oxygen containing gas under conditions such that the stripped gas is discharged to atmosphere and the stripped liquid/ sludge is returned to the aerating tank. In Fig. 1, one form of apparatus for carrying out the process is described. The enclosed aerating tank 1 contains a duct 9 in which are situated a liquid transfer device 11 and an air feed device 12. Under upward flow conditions, the stripped gas consisting of CO 2  and air is expelled to atmosphere 10. The liquid is discharged through the annular passage 14 between the duct 9 and the partition wall 15 to return to the aerating tank. The partition wall has its lower end immersed in the liquid of the aerating tank and its upper end is connected in gas-tight fashion to the roof 5 of the aerating tank, preventing the oxygen-rich gas in the space 6 escaping to atmosphere 10. The stripping operation may be carried out within or outside the aerating tank. The sludge from the settling tank may also be subjected to the stripping, particularly before being recycled to the aerating tank.

Title: Improvements in or relating to organic processes employing boron-halogen-containing compounds
IPC: C07C51/12
Filed: 1936-12-10
Abstract: In the separation of an organic compound from a boron halide catalyst associated with water by distillation so that water is withdrawn from the mixture, the quantity of water in the mixture is maintained above the point at which boron halide decomposes by adding water continuously or intermittently during the process or in one quantity before the distillation.  At atmospheric pressure the necessary amount of water is 2,3-2,5 molecules to one of boron halide, but this ratio is less at lower and more at higher pressures.  The boron halide catalysts mentioned are the fluorine, chlorine, bromine and iodine compounds associated with water, including the oxyacids obtained by reacting hydrochloric, hydrobromic or hydrofluoric acid with boric acid or borates, such as dihydroxyfluoboric acid and hydrofluoboric acid.  In examples, (1) ethylene at 900-1000 lb. pressure is introduced into an addition compound of one molecule each of boron fluoride and water at 120-150 DEG  C., and then carbon monoxide at 600-900 atmospheres is passed in at 175-180 DEG  C.; after driving off a part of the boron fluoride by heating the reaction mixture, steam is admitted and propionic acid is distilled off, the residue being boron fluoride with 2,3-2,5 molecules of water; (2) acetic acid is made from methanol and carbon monoxide, using BF32H2O as catalyst; water is added continuously during the distillation; (3) using BF33H2O as catalyst methyl acetate and acetic acid are obtained, the methyl acetate being distilled off before the intermittent addition of water for the distillation of acetic acid; (4) acetic acid and methyl acetate are made from carbon monoxide and an addition product of CH3-O-CH3.BF3 with 2,5 molecules of water, water being added continuously during the distillation.  The Specification as open to inspection under Sect. 91 includes maintaining the stated proportion of water during the reaction when conditions are such that dehydration occurs.  This subject-matter does not appear in the Specification as accepted.
Patent GB-1508459-A (GB)
Title: Method of firing and furnace therefor
IPC: F23B90/00
Filed: 1975-08-15
Abstract: A combustion chamber (20) of the firing installation is provided with a fuel supply (22) and a primary air supply (24). The outlet of the combustion chamber is connected to a fire space (26) which has a secondary air supply point (28) and a tertiary air supply point (30) with in each case downstream heat-extraction points (32) or (34). The outlet of the flame duct (36) thus formed is connected to a convective heat-extraction point (38), the outlet of which on the flue-gas side is designated by (40). The flame duct (36) is at least partially delimited by refractory ceramic walls (42) and runs out downstream from the fire space (26) in an uncooled mixing space (46). Between the combustion chamber (20) and the fire space (26), a heat-extraction point (48) is connected into the flow path (44) of the combustion gases. In this arrangement, the combustion of the fuel runs in a temporally and spatially extended manner, so that a complete combustion is achieved without inadmissibly high temperatures in spite of a low air excess. The discharge both of uncombusted gases and of nitrogen oxides and sulphur trioxide is thus avoided to a great extent. <IMAGE>

Title: Improvements in or relating to artificial ribbons, tapes, straws, and the like and to the production thereof
IPC: D01D5/04
Filed: 1928-11-21
Abstract: 328,312. British Celanese, Ltd., and Taylor, W. I. Nov. 21, 1928. Yarns and threads. - Flattened or ribbon-like products are obtained by applying a solvent or softening agent to artificial filaments so as to render them sticky or tacky, and then submitting them to pressure in such a manner that the filaments unite to form a ribbon, tape or straw-like product. The pressure may be applied continuously or intermittently so as to produce along the length of the filaments alternately flattened or rounded portions or flattened material of which some parts are greater in width than others. Crinkled products similar to millinery straw may also be produced. The filaments may be treated individuallv with the solvent, or they may be treated while associated as a twisted or untwisted thread, in ,particular, the initial material mav be a knitting cord in which case the product has a crinkled or twisted appearance. Dyes or other colouring matters may be applied to the filaments to be united, for example, a dye or metallic or other powder may be incorporated in the solvent or softening agent; and striped effects may be produced by incorporating coloured filaments. Fine metallic wires or strips such as tinsel may also be incorporated in the flattened product. The treatment is particularly applicable to filaments made of cellulose acetate or other cellulose derivatives, in which case suitable solvents are acetone, triacetin, ethyl lactate, and diacetone alcohol either alone or mixed with water or alcohol. The filaments may be treated continuously with their production, or subsequently thereto. The products obtained may be woven or otherwise formed into fabrics or articles, and they may also be used in millinery or for electric insulation. The solvent is preferably applied in quantities just sufficient to cause adhesion of the filaments ; it may be applied by spraying or immersion of the filaments, as an extremely thin film by means of moistened rollers, rods, wicks, &c., or in the form of vapour. The pressure is conveniently applied by one or more pairs of rollers; and the rollers may be plain, toothed, embossed, or regularly or irregularly corrugated or fluted. As shown, a bundle of filaments 7, Fig. 1, leaving the spinning cell 8 is passed round a feed roller 9 together with, if desired, other yarns &c. from a reel 17, is then passed in contact with a wick 10 depending into a vessel 12 containing the solvent, is next led between a pair of pressure rollers 13, after which it contacts with a second wick 14 moistened with a lubricant such as olive oil, and is finally wound on a roller 15. As regards the pressure rollers 13, both are preferably driven as by gearing 27, Fig. 3, and the upper roller is mounted in a fork 20 and is held in position by means of a screw abutment 19 or is pressed down by a spring or weight. Specification 326,462 is referred to.
