Filed: 1938-05-10
Abstract: 520,824. Valve generating circuits. COSSOR, Ltd., A. C., BEDFORD, L. H., JOFEH, L., and STEVENS, W. H. May 10, 1938, No. 2660/40. Divided out of 519,668. [Class 40 (v)] Relates to an oscillation generator in which a saw-tooth voltage is developed across a condenser, the rapid charge or discharge of which, at flyback in the case of television scanning, is effected by a thermionic valve, and in which the saw-tooth voltage is applied to the grid of an output valve. The output valve supplies a saw-tooth current to an inductive load, a resistance being included in series with the discharge valve and so arranged that during flyback the potential drop in this resistance is superimposed upon the condenser voltage. In this way the current through the valve is cut off throughout the highly positive excursion of its anode at flyback. The Figure shows a condenser C 1  charged through resistance R 1  and discharged by a valve V 2  in series with resistance R 2 . A feedback coupling through condenser C 3  ensures that the discharge valve V 2  is held open throughout the high potential excursion of the anode of the valve V 1 . Synchronizing signals may be applied at the point Sn and are amplified by the valve V 1  and applied to the grid of the valve V 2  by the feedback coupling as positive pulses.

Abstract: 1,197,271. Purification of oxides. DEUTSCHE GOLD - UND SILBER - SCHEIDEANSTALT. 18 Jan., 1968 [21 Jan., 1967], No. 2766/68. Headings C1A and C1N. Finely divided oxides or mixtures of oxides produced by vapour phase oxidation or hydrolysis of chlorides, are purified by introducing the oxide into a treatment zone heated to 400-600‹ C. in which it descends under gravity in countercurrent to an ascending stream of a mixture of steam and an inert gas, the flow of gas being insufficient to fluidize the oxide. The gas mixture is preferably of steam and compressed air preheated to 120‹ C. The oxide may be SiO 2  of s.a. 200 m<SP>2</SP>/gm., TiO 2 , or Al 2 O 3  of s.a. 80 m<SP>2</SP>/gm. The treatment zone may be a vertical tube widened at its upper and lower ends. It may be heated externally by electric heating coils or internally by H 2  burners, the flames being screened from the solid (in this case, steam for the treatment is produced by the burners). The pH of a 4% aqueous dispersion of the oxide is increased from 1À9 to 4 or 4À2 (for SiO 2 ) or from 1À5 to 8À2 (for Al 2 O 3 ).

Title: Improvements in or relating to the manufacture of cellulose derivative emulsions
IPC: C09D101/18
Filed: 1943-02-19
Abstract: In the preparation of a cellulose derivative emulsion of the oil-in-water type containing a water-soluble polyvinyl ester-salt as emulsifying agent, an intermediate cellulose derivative oil-in-water type of emulsion containing the polyvinyl ester-salt in solution is first formed and is stabilized by addition of the whole quantity of water required for the final emulsion, and then a further portion of the water-immiscible liquid ingredients that are to be included in the disperse phase of the final emulsion is added.  The polyvinyl ester-salts are formed between alkali metal or non-metallic bases and polyvinyl esters of carboxylic acids that are only partially esterified.  They include alkali metal salts of polyvinyl phthalate, acetate - phthalate, acetate - citrate, acetate - succinate, and acetate-maleate.  The intermediate oil-in-water emulsion may be obtained by progressive introduction of water into a medium comprising the polyvinyl ester-salt and the cellulose derivative in dissolved condition as a solution or a water-in-oil emulsion obtained by dissolving the dry or water-wet solids in an organic solvent liquid.  If a water-immiscible liquid which is a non-solvent for the cellulose derivative is to be included, it is preferable to introduce it only after the water-stabilized intermediate cellulose derivative emulsion has been formed.  If water-miscible liquids are to be included, it is preferable to introduce them wholly or partly before the stabilized intermediate emulsion has been formed. Pigments may be included and they are preferably introduced at an early stage in the production of the composition.  The emulsions may be used for coating porous materials such as leather, paper, wood, or textiles.  In an example, a lacquer is obtained by mixing nitrocellulose, butyl alcohol, tricresyl phosphate, blown castor oil, a red pigment, a water-soluble sodium salt of polyvinyl acetate-phthalate, ethoxy-ethyl alcohol, and a little water.  A further quantity of water is then added with mechanical agitation of the composition, the addition being slow until phase reversal has occurred, whereupon it is increased.  A quantity of castor oil is then mixed with the water-stabilized emulsion.  In other examples, water-immiscible liquid ingredient which is finally added is rape seed oil, linseed oil, butyl acetate, or tricresyl phosphate.  The cellulose derivative used may be cellulose acetate, ethyl cellulose, or benzyl cellulose.
