Abstract: 1,051,100. Nitrogen tetraoxide. ALLIED CHEMICAL CORPORATION. Aug. 14, 1964 [Aug. 15, 1963], No. 33301/64. Heading C1A. A process for the production of nitrogen tetraoxide from oxidation gases obtained by the combustion of gases containing combined nitrogen (e.g. ammonia) and containing free N 2 , O 2 , NO, NO 2  and water vapour, without net formation of HNO 3 , comprising cooling a stream of the oxidation gases by contact with HNO 3  of concentration 50-68% and so simultaneously reducing the water vapour content of the gas and increasing its content of NO 2 , and subsequently separating nitrogen tetraoxide from the gas by nitric acid absorption and purifying it, wherein the amount of HNO 3  employed to cool the stream of oxidation gas is so regulated that the amount decomposed in this step is at least substantially equal to the amount produced in subsequent steps. One embodiment of the process comprises (1) contacting the oxidation gas with the HNO 3  in a reactor cooler zone under a pressure of at most 1À75 kg./cm.<SP>2</SP> and at 32-45 C. to remove water vapour and increase the NO 2  content while producing dil HNO 3 , (2) subjecting the resulting gases to a pressure of at least 4À5 kg./cm.<SP>2</SP> and at 20-80 C. to oxidize NO to NO 2  by O 2  in the gas stream while producing concentrated HNO 3 , (3) absorbing NO 2  from gas stream by countercurrent scrubbing with 85-95% HNO 3  producing a NO 2 -HNO 3  concentrate and a gas stream comprising O 2 , N 2  and small amount of nitrogen oxides and HNO 3 , (4) scrubbing gas stream with water to remove nitrogen oxides and producing a dilute HNO 3  and a waste stream of N 2  and O 2 , (5) distilling NO 2  from the concentrate and condensing it as N 2 O 4 , (6) returning HNO 3  distillation residue to (3); (7) concentrating di] HNO 3  from (1) and (4) to 50-68% HNO 3  for use in (1); (8) returning concentrated HNO 3  from (7) and remaining HNO 3  produced during the process to (1), this HNO 3  is then contacted with the oxidation gases and there is no net production of HNO 3 . Referring to the figure, ammonia is oxidized in 4 and gases pass to reactor cooler 11 where water vapour content is reduced to less than 2% by weight by contact with HNO 3 , the gas is then compressed and passed to reactor condenser 23 where NO + H 2 O # HNO 3 , remaining gases pass to oxidizer 37 where NO + O 2  # NO 2  the NO 2  being absorbed in 41 by contact with 85-95% HNO 3  to form NO 2 -HNO 3  concentrate which is distilled in 69 to NO 2  which is condensed in 87, residual NO is oxidized in 106 and N 2 O 4  product is removed via 111; dil HNO 3  from 11 and 23 is concentrated in 126 and recycled to 11, concentrated HNO 3  from 71 is recycled to 41.

Abstract: 1,054,774. Liquid diffusion apparatus. G. G. HAVENS. July 2, 1966 [July 10, l962], No. 26132/63. Headings B1X and B2K. A solvent separation apparatus includes a plurality of elongate rigid porous tubes having a semipermeable membrane on either the inner or outer surface thereof, the tubes being operative to pass water at a higher rate than dissolved salts and means for circulating a solution at a pressure exceeding the osmotic pressure difference across the membrane. Saline water is maintained at 1000 to 1500 p.s.i. by pump 12, the water being circulated by way of tubes 14, tank 18 and pump 20. A salinity monitor automatically bleeds off brine at valve 22 when the salt concentration is high. Tierods 44 through end supports 36 hold the porous tubes against gasket 40 in the pressure vessel 24. The tubes are made from a glass fibre screen, mesh or fabric impregnated with a phenolic resin thereby giving a porous tube upon curing. The tubes are manufactured by winding with a bias ribbons of resin impregnated fabric on a mandrel coated with a parting agent. The wound mandrel is wrapped in cellulose acetate, cured at 180‹C for 2 hrs. and the cellulose acetate removed. A solution of cellulose acetate, acetone and aqueous magnesium perchlorate is used to coat the porous tubes which is subsequently treated at room temperature, 0‹, 30 to 50‹ and finally 80‹C. The porous tubes may be modified by interposing a layer of unimpregnated fibre e.g. a spiral wrapping of glass fibre roving, between the impregnated tube and the semi-permeable membrane. A further modification is the use of a pattern of grooves to promote the formation of conical pores or gaseous inclusions which aid diffusion speeds. An alternative embodiment (Fig. 5, not shown) incorporates a series of cylindrical tubes closed at one end within a pressure vessel, the vessel containing saline water while the membrane is on the outside of the tubes.

Abstract: 1,232,703. Mixing liquids. COULTER ELECTRONICS Ltd. 17 April, 1968 [17 April, 1967], No. 10970/70. Divided out of 1,232,701. Heading B1C. Apparatus for diluting blood samples comprises a vessel 42 having a downwardly angled tangential inlet 40 and a drain conduit 100 which enters tangentially the vessel 54. In operation the sample and diluent are introduced successively through the inlet 40 and follow a helical path down the vessel wall collecting in a swirling pool without turbulence which might generate undesirable microscopic bubbles. Gas pressure applied to the top of vessel 54 prevents discharge through the conduit 100 and causes large bubbles to rise therefrom and mix the liquids. The mixture is then transferred to vessel 54 by application of gas pressure to the top of vessel 42, enters the vessel 54 also tangentially without turbulence and is further agitated by large bubbles from conduit 100. The sample is discharged through the valved drain tube 114. Some of the liquid may be withdrawn through the siphon tube 52 the inlet of which is above conduit 100 so that bubbles cannot enter.

A smoking device, i.e. a cigarette, cigar, cigarette holder or pipe, has a smoke filter comprising microporous glass particles in the form of granules or fibres having a structure of interconnecting pores. The particles, which may be made surface-active by the incorporation of metal ions, may be contained in a cartridge, used in combination with other filtering media such as charcoal and, when in fibrous form, combined with cellulose fibres and formed into paper. Microporous glass fibres may also be mixed with the tobacco of a cigarette, when they serve the additional function of holding the tobacco ash together. An embodiment of composite filter for cigarettes comprises a cartridge of microporous glass granules sandwiched between an element of cellulose paper at the mouthpiece end and an element composed of microporous alkali borosilicate glass and cellulose fibres. The microporous glass is produced by using a composition that can be heated to separate into a major phase that is relatively insoluble by acids such as hydrochloric, sulphuric or nitric, and a minor but continuous phase that can be leached out by such acids. The glass is crushed and sieved to form granules, or formed into fibres before the leaching process. After leaching the particles may be washed and then heated in an atmosphere of water vapour and nitrogen to increase the concentration of hydroxyl groups on their surfaces.

Abstract: 1,258,483. Viscose fibres. CIBA-GEIGY A.G. 16 Sept., 1969 [1 Oct., 1968], No. 45684/69. Heading B5B. [Also in Divisions D1-D2] Viscose fibres with novel dyeing properties are prepared by adding to the spinning composition a polyamine-amide formed by reaction of (a) an unsaturated fatty acid with at least 12 and preferably less than 18 carbon atoms, its dimer or polymer with (b) a polyalkylene-polyamine and optionally the reaction product of (c) a polyepoxide compound with (d) a polyalkylene-polyamine, the total weight of the additive(s) being 1 to 20% by weight based on the cellulose. The viscose additive, which may be 90 to 10% by weight of the reaction product of (a) and (b) and 10 to 90% by weight of the reaction product of (c) and (d), may be added to the spinning solution as an aqueous solution, organic solution or in a dispersed form. The solutions or dispersion of additive may contain a non-ionic emulsifier, for example ethylene oxide addition products of alkyl phenols, amines or alcohols. The polyepoxide may be the reaction products of bisphenol A and epichlorohydrin. The polyalkylene polyamine (b) and (d) may be ethylene diamine, diethylene triamine and triethylene tetramine. Unsaturated fatty acids used in the examples are those from castor oil, tall oil and polymerized linoleic acid. The viscose is wet spun in the usual manner into a coagulation bath of, for example, sulphuric acid, washed in subsequent baths, desulphurized with dilute aqueous sodium sulphide and sodium hydroxide, washed and brightened. The fibres so produced may be dyed with acid wool or dispersion dyestuffs. Thus mixed fabrics of the treated cellulose material with untreated cellulose wool/polyamide or polyester fibre material may be differentially dyed.
