Patent GB-802062-A (GB)
Title: Suspension polymerization
IPC: C08F2/16
Filed: 1956-02-27
Abstract: Polymeric granules are prepared by mixing one part of a polymerizable liquid which is not self-emulsifiable with at least 0.5 parts by volume of an aqueous non-solvent liquid medium and a water-insoluble solid material, capable of being dispersed as colloidal particles having dimensions in the order of 0.01 to 50 microns and having a balance of hydrophilic-hydrophobic properties such that the particles tend to collect in the aqueous medium at the water-oil interface, in amount barely to cover the surfaces of the polymerizable liquid when the latter is in the form of droplets of the desired size, agitating to disperse the polymerizable liquid as droplets smaller than those desired, continuously passing the dispersion in non-turbulent flow through a channel, where limited coalescence occurs, to a second mixing zone, increasing the apparent viscosity of the medium by adding with gentle agitation a water-dispersible thickening agent, and subjecting the resulting dispersion without turbulence to conditions conducive to polymerization.  The polymerization step may be conducted continuously or batchwise.  The polymerizable liquid may comprise one or more vinylidene compounds, e.g. styrene or substituted styrenes such as divinyl benzene acrylic and methacrylic esters, vinyl chloride and vinylidene chloride, and may contain plasticizers and preformed polymers.  Specified colloidal materials are metal salts, oxides and hydroxides, clays, e.g. bentonite, raw starches, sulphonated cross-linked high polymers and resinous polymers.  The aqueous medium may also contain (1) water-soluble promoters which affect the hydrophilic-hydrophobic balance of the colloidal particles, e.g. sulphonated polystyrene, alginates, carboxymethylcellulose, tetramethyl ammonium hydroxide or chloride, condensation products of diethanolamine and adipic acid, ethylene oxide, urea and formaldehyde, and polyethyleneimine, gelatin, glue, casein, albumin, glutin and methoxycellulose; (2) electrolytes, e.g. polyvalent metal salts; (3) peptizing, flocculating, deflocculating and surface-active agents and sensitizers; and (4) water-soluble, oil-insoluble polymerization inhibitors.  The thickening agent may be sulphonated polystyrene, hydrophilic clays, e.g. bentonite, digested starches, natural gums and carboxy-substituted cellulose ethers.  The dispersion may be concentrated by creaming and the thickening agent added as an aqueous concentrate.  Monomer-soluble, water-insoluble catalysts, e.g. benzoyl peroxide, may be added to the polymerizable liquid before dispersion.  Specification 802,061 is referred to.

Abstract: 998, 651. Automatic control of boiler feed water. COMBUSTION ENGINEERING Inc. Feb. 18, 1964 [March 25, 1963], No. 6692/64. Heading G3R. A system for controlling the flow of feed water to a vapour generator such as a once through boiler is controlled by means of a pair of flow meters, one of which is most efficient at low load demands and the other of which has its highest efficiency at high load demands, means being provided to ensure a smooth transition from the control by one meter to control by the other meter as the load on the vapour generator increases. Feed water is supplied by means of a pump 12 by way of a high demand efficient flow meter 14 and a valve 16 to the various elements of a vapour generator 10 the valve 16 having a by-pass including a low demand efficient flow meter 32 and a valve 34. The outputs from the detecting means 36, 38 of the flow meters 14, 32 are applied to a ratio device 40, 401, the output from the detector 36 also controlling a servomotor 41 associated with the ratio device 40, 40<SP>1</SP>. At low load demands (0-20%) the contact arm of the ratio device is at the left hand end so that the signal to a controller 44 is derived from the set point value 43 and the low demand flow meter 32. A second ratio device 46, 46<SP>1</SP> has its contact arm at the left hand end so that the controller 44 controls the valve 34 only. As the load on the vapour generator increases beyond 20% the servomotor 41 runs to gradually reduce the effect of the signal from the flow meter 32 and increase that from the flow meter 14, the motor 48 being simultaneously actuated to close valve 34 and open valve 16, the change over being completed at about 25% demand. The system further includes means for controlling the admission of water to a . de-superheater 26 to control the temperature of the steam output of the generator such means including a steam temperature sensor 56, a changeover switch 58 and a control valve 54.
