Title: Improvements in or relating to the production of organic nitrogen compounds
IPC: C07C205/40
Filed: 1944-12-11
Abstract: Oxy-nitrogen derivatives of certain organic compounds having at least one radicle selected from nitroso and nitrite groups are treated with nitrogen tetroxide with or without oxygen present, or with nitrogen trioxide or nitric oxide in the presence of oxygen whereby the nitroso and nitrite groups are converted into nitro and nitrate groups respectively, said organic compounds being selected from aliphatic compounds containing at least two carbon atoms and alicyclic or aliphatic-alicyclic compounds containing at least five carbon atoms in the ring; preferably, the compounds are hydrocarbons. In particular, nitro aliphatic compounds may be prepared from saturated aliphatic or nitro-aliphatic nitroso compounds and nitro-aliphatic nitrates from saturated nitroso-aliphatic or nitro-aliphatic nitrites, especially where such compounds contain not more than eight carbon atoms, and the corresponding nitro-alicyclic and nitro-aliphatic-alicyclic compounds may be prepared from the respective saturated alicyclic or aliphatic-alicyclic compounds.  The reaction is preferably carried out in the liquid phase, for example, by bubbling oxygen or oxygen-containing gas through a mixture of the organic nitrogen compound and nitrogen tetroxide.  Solvents may be present. Generally reaction is effected at between 0 DEG  and 20 DEG C. and at atmospheric pressure.  In examples: (1) oxygen is passed through a mixture of 1-nitroso-2-nitroisobutane, nitrogen tetroxide and methylated ether at 10 DEG  C. to yield 1,2-dinitroisobutane; (2) oxygen is passed into a mixture of b -nitroethylnitrite and nitrogen tetroxide at 10 DEG  C. yielding 3-nitroethylnitrate; (3) 1,2-nitronitroso-cyclohexane is dissolved in nitrogen tetroxide, the mixture allowed to stand 24 hours and dinitrocyclohexane recovered therefrom.  It is stated that dinitro-octane may be produced from nitro-nitroso-octane.  According to the Provisional Specification, oxidising agents, generally, may be used.

Patent GB-824577-A (GB)
Title: Improvements in or relating to the orientation of polyester filaments
IPC: D02J1/22
Filed: 1957-08-07
Abstract: <PICT:0824577/IV (a)/1> A tow bundle comprising a thick sheet of closely spaced polyester filaments is contacted with a first inert liquid maintained at 40-70 DEG  C. and then drawn at a draw ratio of at least 2.3 while again contacting it with an inert liquid, which may be the same as or different from the first liquid, maintained at 60-100 DEG  C., the temperature of the liquid in the second step being at least 10 DEG  C. above that of the liquid in the first step. The polyester may be polyethylene terephthalate or terephthalate polymers of other glycols of the series HO(CH2)nOH, where n is 2-10. The polyester may also be a polyethylene terephthalate copolymer containing in the molecule residues of sebacic acid, isophthalic acid, sodium sulphoisophthalic acid or polyethylene glycol.  The undrawn tow bundle may consist of substantially unoriented filaments and may have a density in excess of about 40,000 undrawn denier per inch measured across the width of the bundle. Preferably the tow is not allowed to cool after contacting the first inert liquid and before contacting the second liquid.  The liquid may be water and may contain softening, wetting or antistatic agents.  As shown, the first contacting is effected by causing the tow bundle to travel in a sinuous path in succession over 8 rolls driven at a uniform speed, rolls 4 and 5 being partially submerged in a bath of an aqueous liquid maintained at a constant temperature within the range 40-70 DEG  C.  Rolls 5-7 are heated to the same temperature as the bath, while roll 8 and subsequent rolls 9-16 are not heated.  Between rolls 8 and 9 an aqueous liquid maintained at a temperature within the range 60-100 DEG  C. is sprayed on to the tow bundle as it travels in a horizontal path.  The bundle then travels in a sinuous path over seven further rolls 10-16 driven at a uniform peripheral speed 2.3-5.8 times that of rolls 1-8.  The process increases the uniformity of orientation and dyeability of the filaments. Specifications 578,079, [Group IV], and 721,912 are referred to.

Abstract: 1365226 Rotary shaft seals; valves CHARLES-WESTON & CO Ltd 23 May 1973 [30 May 1972] 25130/72 Headings F2B and F2V In sealing means for apparatus, e.g. a clutch device 47, in which operating fluid is transmitted through a rotary shaft 11 from a stationary pipe comprising a casing 10 having a fluid inlet and encircling the shaft, a sleeve 16 rotatable with the shaft, and spring-loaded end face seals 41 housed in a chamber 21 between the casing and the sleeve to seal the gap therebetween, the sleeve is provided with valve means 24A, 24B which allows passage of fluid to and from the rotary shaft below a predetermined shaft speed but prevents it at or above that speed to enable the pressure in the chamber to be relieved. The casing is connectible to a source of air pressure through an inlet pipe 14 and a manually operable valve having feed, exhaust and off positions A, B and C respectively. An axial bore 19 in the shaft communicates via a radial bore 20 with a chamber 18 between the shaft and the sleeve. The valve 24A is centrifugally operated to close at the predetermined shaft speed. The valve 24B is a check valve allowing air to pass to the bore 19 and has a stem 25 abutting an actuating ring 26 located by pins 27 and urged by springs 29 against a manually operable emergency valve 33 disposed diametrically opposite the pins. The stem 32 of valve 33 has a wedge-shaped head that normally engages a corresponding groove 30 in the ring 26. A bore 37 in the stem opens the chamber 18 to atmosphere through a passage 38 in the valve body 34 when the valve is open as in Fig. 2. The end face seals comprise rotary sealing rings 43 urged by springs 44 into contact with stationary rings 45. In operation, when the clutch drive shaft 45 rotates slowly, air is admitted to the shaft bore 19, and shaft 11 rotates at the drive shaft speed. Acceleration of the drive shaft to normal speed causes the centrifugal valve 24A to close and the valve 15 may then be operated to reduce the pressure in chamber 21 to atmospheric, thus relieving the load on the seals 41, whilst maintaining the pressure in the device 47. In an emergency pressure may be released in the bore 19 by operating valve 33. In addition, a further pressure release valve (not shown) may be fitted in the chamber 21.

The silencer shell 1 is made in pressed halves to which an inlet pipe 2 and an outlet pipe 3 are welded. A perforated tube 4 is connected to the inlet pipe and is supported in the shell by partitions 5 which form chambers 6,7 and 8. The downstream end of the tube 4 is spaced from the end of the outlet tube by a distance a, and is spaced from the end of the shell by a distance b to form a spark trap. Two lateral baffles 9 are fixed in the tube and each baffle is formed with a number of inclined vanes which give a rotary motion to the gas stream. The two baffles are angularly displaced relative to one another by an angle α, calculated from the expression α=<SP>#180xk</SP> n , where n=number of vanes and k= the overlap constant and has a value 0À3-1À0. When k=1À0, the maximum overlap prevails and the minimum straight-through gas flow is obtained. The distance between the baffles is greater than the diameter of the tube in order to minimise the resistance to flow. The vanes extend radially from a central sleeve 11 to the inner wall of the tube. In operation, burning particles which would appear in the exhaust gases as sparks are thrown outwardly by centrifugal force and pass through the perforations into chambers 7 and 6. Typically, for a 40-80 horsepower engine, the silencer has a volume of 7À5 litres and the vanes are inclined at 37 degrees to the baffles.
