Patent GB-1049846-A (GB)
Title: A process of treating boron compounds
IPC: C07C29/52
Filed: 1965-03-30
Abstract: Deposition of boron-containing material from a substantially oxygen-free mixture of liquid hydrocarbon and a boric acid in contact with a surface at 195 DEG  C. or more is prevented by including an alcohol in the mixture.  The alcohol is preferably a monohydric alcohol. Thus, in a process for the production of an alcohol by oxidizing a hydrocarbon with oxygen-containing gas in the presence of a dehydrated form of ortho-boric acid, the vapours comprising hydrocarbon and water are removed from the oxidation reaction mixture, contacted with liquid hydrocarbon, thus heating the hydrocarbon and cooling the vapours, the heated liquid hydrocarbon which is substantially oxygen-free but contains boric acid is contacted in the presence of 0.05-5 moles of a monohydric alcohol per equivalent of boric acid with a surface at 195 DEG  C. or more, and the resulting heated hydrocarbon is introduced into the oxidation reaction mixture.  The alcohol may have the same carbon skeleton as the hydrocarbon to be oxidized.  Hydrocarbons mentioned are butane, pentane, methyl butane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, methylcyclopentane and methylcyclohexane. Alcohols mentioned are methanol, cyclohexanol, n-hexanol, iso-propanol, n-octadecanol, ethylene glycol and glycerol.

Title: Improvements in or relating to the manufacture of water soluble sodium salts of carboxymethyl-cellulose
Inventor: RIGBY CHARLES HERBERT
IPC: C08B11/22
Filed: 1950-06-02
Abstract: In the manufacture of water-soluble sodium salts of carboxymethyl cellulose, a slurry of the salt in an aqueous solution of a water-miscible alcohol is fed on to a moving endless belt of gauze, a portion of the solution is allowed to drain through the gauze, and a further portion of the solution is expressed from the resulting loose fibrous layer by passing the portion of the belt carrying this layer through the nip of one or more pairs of pressure rolls.  The alcohol may be methyl, ethyl or isopropyl alcohol.  In the example 10 parts of crude sodium carboxymethyl cellulose containing alcohol, water, excess caustic soda and by-product salts are slurried with a mixture of 60 parts by weight of industrial methylated spirits, and 40 parts of water. The excess caustic soda is neutralized with nitric acid of 50 per cent concentration by weight and the slurry thus obtained is continuously pumped from a reservoir in which it is kept stirred on to an endless belt of wire gauze travelling at 7.8 f.p.m.  The bulk of the liquor drains through the gauze, leaving a layer of about one inch depth of the wet sodium carboxymethyl cellulose on the belt, which layer passes through the nip of a pair of 11-inch diameter rubber-covered rolls, where a further quantity of liquor is pressed out.  The thick compressed sheet emerging from the rolls and still containing about 60 per cent by weight of liquor is sprayed with aqueous industrial methylated spirits of 55 per cent by weight concentration in the ratio of 2.6 parts by weight of spirits to one part of sodium carboxymethyl cellulose.  The endless belt carrying the sheet of washed material then passes through the nip of a second pair of rubber-covered rolls, where the bulk of the wash liquor is squeezed out.  The compressed sheet of material leaving the second pair of rolls contains about 60 per cent of aqueous alcohol and is removed from the belt by means of a doctor knife.  The process avoids the loss of alcohol and very tight packing of the cake of the product which occurs in the usual centrifugal separation and washing process.

Abstract: 661,427. Lens mounts. KODAK, Ltd. May 27, 1949 [May 28, 1948], No. 14255/49. Class 97 (i). A lens mount carries an objective comprising at least four components separated by air spaces, one of which is of zero power, and includes means for focusing the objective as a whole to vary the magnification, means for varying the thickness of the air space of zero power and means for co-ordinating the change in air space with the change in magnification to maintain a flat image field at different magnifications. The mount shown comprises lens cells 18 and 36, of which cell 18 carries a plano-concave lens 12 and a cemented doublet 11, whereas cell 36 carries a plano-concave lens 14 and a cemented doublet 17. A pin 21 secures cell 18 to a barrel 19 for axial movement therewith and a pin 38 on this barrel projects into an axially-extending slot 39 in the periphery of cell 36 to prevent rotation of this cell and allow relative movement of the cell and barrel. Threaded on the cell 36 at 54 is a member 42, which is secured to barrel 19 for axial movement therewith by a headed screw 44 that passes through a curved slot 45 in member 42. The latter has a pin 50 that projects into an axial slot 51 in a focusing ring 25, which is threaded on the lens barrel 19 at 26 and has a pin-and-slot connection 27, 29 with a fixed sleeve 20, whereby rotation of ring 25 is allowed but axial movement thereof is prevented. A pin 23 on the sleeve 20 extends into an axial slot of barrel 19. The threads 26 and 54 are of different pitch so that, when the ring 25 is rotated to vary the magnification, the lens barrel 19 and the cells 18 and 36 move axially and the cell 36 has imparted thereto a further movement relative to the cell 18 and barrel 19 to change the thickness of the air space 16 and thus maintain the image field flat. In another form, the focusing ring 25 is provided with an internal flange and this flange is provided with a helical slot in which a pin on lens cell 36 engages, this slot serving the same purpose as the screwthread 54,
