Title: Improvements in or relating to the manufacture of cellulose esters
IPC: C08B3/22
Filed: 1943-04-05
Abstract: Cellulose esters, such as cellulose acetate, propionate, butyrate, acetate - propionate, acetate-butyrate, p  acetate-stearate, are prepared by esterifying cellulose in the presence of an inorganic acid catalyst, e.g. sulphuric or phosphoric acid or mixtures thereof, and a solvent for the cellulose ester, and ripening the solution so obtained, wherein before or during the ripening operation a neutralizing compound of aluminium, e.g. aluminium acetate or hydroxide, is added to the solution in an amount such that part only of the catalyst is neutralized.  The inorganic catalyst is present preferably in an amount between 10 and 20 per cent, and the neutralizing compound is added so as to leave preferably 4 to 8 per cent of the free catalyst, calculated on the weight of cellulose employed.  The neutralizing compound may be added, together with or separately from the necessary amount of water for the ripening operation, and the water may be added in two or more stages.  The invention makes it possible to effect the ripening operation at a higher temperature, and in a shorter time, and it may be conducted as a continuous process.  The invention is particularly suitable for the manufacture of an usually stable cellulose acetate of high acetyl content.  In the example, cotton linters are pretreated with a mixture of acetic acid, acetic anhydride and a small amount of sulphuric acid, and an esterification mixture of acetic acid, acetic anhydride and sulphuric acid is added and the temperature maintained below 40 DEG  C.  A solution of aluminium acetate in aqueous acetic acid and the water necessary for the ripening operation are stirred into the acetylation mixture and ripening proceeds at 60 DEG  C. for 3 or 6 hours depending upon the acetyl value required.  Finally, a large amount of water is added and the precipitated cellulose acetate is washed and dried.

Abstract: 1,040,063. Preheating cement raw materials. MIAG MUEHLENBAU UND INDUSTRIE G.m.b.H. Feb. 11, 1963 [Feb. 27, 1962], No. 5411/63. Heading F4B. [Also in Division BI] Granular or powdered material is treated with a gas by passing the gas upwards through a downwardly flowing stream of solid, the gas velocity being greater than the velocity at which individual particles of the material are supported by the gas, and the rate of feed of solid being such that clouds of material are formed which drop through the region of greatest velocity of the gas stream upon reaching a critical density. Material carried overhead is removed from the gas stream in a separator and returned to the vessel. As shown in Fig. 1, a reaction vessel having a tapering lower portion ending in a nozzle 3 is supplied with solid through line 12 and with gas from pipe 9. The gas passes around a flange 5 on the nozzle 3, and passes upwardly to suspend the descending solids. As the density of the solid clouds builds up, the cloud falls through the nozzle 3 and is collected by conveyer 11. Outgoing gases leave through line 13 and solids separated in cyclone 16 are returned to the reactor. A number of cyclone separators external to the reaction vessel may be employed, to some of which the incoming reactant is fed. The axis of the reaction vessel may be curved and in one case the nozzle 3 opens into the end of a rotary kiln used in cement preparation.

Title: Improvements in or relating to a power assister for manually or like operated mechanisms
Inventor: BAMFORD DENBY CHADBURN
IPC: G08B9/08
Filed: 1951-03-10
Abstract: 711,797. Order-telegraph signalling - apparatus. CHADBURNS (LIVERPOOL); Ltd. March 10, 1952 [March 10, 1951], No. 5831/51. Class 118 (2). A manually-operable mechanical remote control installation, e.g., a mechanical telegraph as in Specification 673,533, having a rotatable operating handwheel and a power assister electric motor, in which the operating wheel has a hand-grip part proper which is permitted limited movement relatively to the wheel and is arranged, in relation to a switch mechanism controlling the power assister, so that pressure on the hand-grip actuates said switch mechanism to bring the power assister motor into operation and release of said pressure operates said switch mechanism to stop the power assister motor, is provided with further switch-means controlling the power assister motor wherein said further switch-means is operatively connected to transmission shafting between the transmitter and receiver of the installation so as to be operated to bring the power assister into operation only when the said transmission shafting has been actually moved manually. This overcomes the tendency of power-assisted hunting. In the Fig. handwheels 12 and 13 drive, by shafting 16 and 18 respectively the "order" pointer 14 and "revolutions" indicator 15. Switches in the handwheels Figs. 3 and 4 (not shown) operated by pressure on the handles prepare the circuits of motors 21 and'magnetic clutches 20 but change-over switches 41 (in series with the respective handwheel switches as in Fig. 2, not shown) are not operated until the shafting 16 or 18 is actually turned, whereupon the appropriate friction clutch 42 operates its switch 41 to bring the motor 21 into action. The friction clutch 42 allows the shafting to rotate without further action on switch 41 until a change in direction of rotation is effected (by reversing the handwheel) when switch 41 is caused to change-over and provide power assistance in the reverse direction. Besides the magnetic clutches 20, which are energised simultaneously with the. motors 21, magnetic brakes may also be operated by the same switches so that as soon as a motor 21 is switched off and the clutch disengaged a brake is applied. Further damping of the system may be provided by the use of slugged relays, and speed control may be effected by the pressure applied to the handwheel acting on a carbon pile resistance in the motor circuit. Series wound motors are preferred.

Filed: 1953-03-03
Abstract: A resin stable in aqueous solution is prepared by heating 3.6-5 mols. of formaldehyde with 1 mol. of dicyandiamide and 0.3-1 mol. of boric acid until the product is soluble in water on extreme dilution.  The boric acid may be added before, during or after the condensation between the other two ingredients.  In the example dicyandiamide and aqueous formaldehyde were refluxed until the product had passed the insoluble stage and become soluble on extreme dilution.  The product was then refluxed for 2 hours with a boric acid solution.  A stable resin solution resulted which was useful for treating leather or paper or for crease-resisting fabrics. or for treating fibres of fabrics of wool, silk or acetate rayon or felt.  The resin may be precipitated from the solutions by addition of a water soluble anionic sulphonate or sulphate, e.g. sodium or ammonium salts of sulphonated phenol- or naphthalene-formaldehyde condensates, sulphonated castor, neat's-foot or linseed oil, sulphite lignin, or cetyl, lauryl or stearyl sulphate, followed by acidification with aluminium sulphate.  Specification 736,955 is referred to.ALSO:Water-soluble products obtained by condensing dicyandiamide with formaldehyde in presence of boric acid (see Group IV(a)), are used for treating fabrics or fibres of wool, silk or acetate rayon or felt, e.g. for making fabrics crease-resistant.

Patent GB-165897-A (GB)
Title: Improvements in and relating to lubricating oils and the manufacture thereof
Filed: 1920-02-27
Abstract: Lubricating oils are obtained by purifying crude hydrocarbon oils in such manner that, while all mineral acid is removed, up to 3 per cent of organic acid or phenolic or other acidic bodies are retained.  In an example, crude Texas oil is treated in the usual way with sulphuric acid or liquid sulphur dioxide, sulphur is removed by any known process, and the product is washed with water only to such an extent as to ensure the removal of all sulphuric acid.  The percentage of retained sulphonic acids may, if necessary, be reduced by mixing with acid-free oil.  In a modification, hydrocarbon oils containing glycerides may be treated with steam until the desired percentage of free fatty acid is produced by hydrolysis of the glyceride.
