Title: Process and apparatus for the separation of soot from a suspension thereof in water by means of agglomeration
Inventor: VISSER PIETER
IPC: B01J2/28
Filed: 1969-06-16
Abstract: 1,274,067. Mixing apparatus. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 16 June, 1969 [18 June, 1968], No. 30296/69. Heading B1C. [Also in Division C1] Water containing suspended soot is fed via inlet 4 into the space between a cylindrical casing 1 and a rotating cylinder 2 to which is fixed an agitator 3. An agglomerating agent, e.g. a heavy oil, is added through a inlet 5. Water and agglomerated impurities flow past a baffle 6, which ensures that some of the agglomerated impurities are always present in the space between casing 1 and cylinder 2, through an outlet 7 and onto a filter 8 from which separated impurities flow through a discharge 10, e.g. a tube or gutter, and water flows through a discharge 9. The concentration of suspended impurities in the discharged water is measured by a photometric device 12 and compared with an arbitrary valve by a device 13 the output of which actuates a device 14 incorporating a timing mechanism to regulate the flow of agglomerating agent through a valve 15. If the concentration of suspended impurities exceeds the set value, discharged water may be recirculated. The rotatable cylinder may have a hollow portion (25), Fig. 3 (not shown), having vanes (26) and slits (27) through which the water and agglomerated impurities pass into an apertured tube (28) and into a compartment (30) of the casing (23) formed by a partition (29). Agglomerated impurities may be discharged from the space between the rotatable cylinder and the casing (23) through an outlet (32).

Title: Process for the manufacture of coloured derivatives of polyhydroxylated substances of high molecular weight
IPC: C08F8/00
Filed: 1958-09-23
Abstract: Coloured derivatives of polyhydroxylated substances of high molecular weight, such as cellulose and polyvinyl alcohol, are manufactured by partially etherifying or esterifying the substance with a dyestuff radical and then reacting the product with an esterifying, etherifying or acetalizing agent.  The dyestuff preferably contains as groups imparting solubility in water carboxylic acid groups or preferably sulphonic acid groups, and also preferably contains at least one group containing at least one labile halogen atom, for example a chloropropionyl group.  It is especially advantageous to use a dyestuff that contains a group of the formula: <FORM:0871087/IV (a)/1> in which n is a whole number not exceeding 4, and Z represents an unsubstituted or advantageously a substituted amino group or a substituted hydroxyl or mercapto group or a chlorine atom.  In an example, 100 parts of powdered alphacellulose are mixed with a solution of 2 parts of a red dyestuff having the formula: in 750 parts of water and first 35 parts of sodium chloride and then 2,5 parts of soda ash are added and the mixture stirred for 90 minutes at room temperature.  The resulting dyed powder is treated with a wetting agent, washed with water, alcohol and ether and dried in vacuo at 60 DEG C. 10 parts of the dyed cellulose powder is pasted with N-perchloric acid, filtered, pressed, dispersed in benzene, cooled to 0 DEG C. and acetylated for 2 1/2 hours at 0 DEG C. with acetic anhydride.  The resulting red cellulose triacetate is filtered and washed with water.  In a second example, cellulose is dyed with a dyestuff having the formula:  <FORM:0871087/IV (a)/2> in a third example with a dyestuff having the formula:  <FORM:0871087/IV (a)/3> and in a fourth example with a dyestuff having the formula: <FORM:0871087/IV (a)/4> In all three cases the dyed cellulose is acetylated with acetic anhydride.  The acetylated products obtained in the above examples are dissolved in methylene chloride and used for casting films and making spun-dyed filaments.  In a fifth example, 10 parts of polyvinyl alcohol are reacted with the dyestuff used in Example 1 in aqueous solution in the presence of sodium carbonate, precipitated by adding a saturated aqueous solution of sodium chloride and washed with a saturated aqueous solution of sodium chloride.  The coloured polyvinyl alcohol is dissolved in 300 parts of water at 70 DEG C., 3,7 parts of formaldehyde added and the temperature raised to 100 DEG C.  2 parts by volume of concentrated hydrochloric acid are then slowly added followed by 0,5 part of sodium perchlorate, the precipitate of red acetalized dyed polyvinyl alcohol formed is filtered off and washed.  Dyed polyvinyl alcohol may be reacted with a ketone to form a ketal or with acetaldehyde, benzaldehyde or butyraldehyde to form acetals. Specification 868,470 is referred to.

Abstract: 771,823. Reciprocating electric motors. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 24, 1955 [Oct. 27, 1954], No. 30399/55. Class 35. [Also in Groups XVIII and XL (b)] In an electric timepiece the maintaining circuit for the oscillating control member, e.g. the balance 1, Fig. 1, includes a quantity of radioactive material 4 and a detector 5 which is sensitive to radio-active radiation. As the balance swings in the direction of the arrow the detector 5, e.g. a photo-transistor is activated and the capacitor 8 discharges through the magnet coil 6 which attracts the armature 7 and impulses the balance. The value of the capacitor 8 and the resistor 10 are adjusted so that no appreciable impulse is given to the balance as it swings in the return direction. If desired the maintaining circuit may include a switch, e.g. a flip-flop which passes only one in two control signals to the magnet coil so that the balance is impulsed in one direction only. An apertured screen may be provided to obstruct the radio-active radiation until the balance is in the correct position. The detector may be on the balance and the quantity of radio-active material may be housed in a lead protective envelope. In another embodiment, Fig. 2, the balance is impulsed in both directions of movement, two detectors 5<SP>1</SP>, 5<SP>11</SP> being provided. The balance and its support and the detector or detectors may form an interchangeable unit.

[Classes 29 and 64(i)] In a substantially closed cooling system for an electrical generator 1 driven by a steam turbine through a shaft 7, cooling gas is withdrawn from the generator 1 through a pipe 2, is compressed by a compressor 3, is cooled at substantially constant pressure in coolers 4a, 4b, fed with condensate from the steam turbine and in cooler 4c fed with circulating water, drives the impeller of a gas turbine 5 which is coupled to the compressor 3 by a shaft 6 and passes back to the generator 1 to cool the windings. The cooler 4b is supplied with fresh condensate and the cooler 4a with condensate which has undergone one stage of pre-heating (i.e. feed-heating), the condensate then undergoing two further stages of feedheating. The shaft 6 may be driven either by the steam turbine shaft or by an electric motor 8. If the cooling fluid is air, a vent fitted with a filter is inserted in the connection between the compressor 3 and the precooler 4a, or air may be withdrawn from the generator 1 by an auxiliary compressor so maintaining the pressure in the generator 1 less than atmospheric. If hydrogen is used as the cooling fluid the pressure is maintained greater than atmospheric and the system is not vented. De-icing equipment may be fitted.
