摘要： A process for preparing a structured composite pigmentary material comprises forming a dispersion of uncoated particles of titanium dioxide at a pH value at which the particles have a surface charge and subjecting the dispersion to cross-flow filtration until the dispersion contains more than 50% by weight titanium dioxide. The concentrated dispersion is mixed with a dispersion of chemically distinct particles having a surface charge of opposite sign under conditions which ensure that the sign of the surface charge on either of the particulate materials is not reversed. In the resultant composite pigmentary material the titanium dioxide particles are held in association with the chemically distinct particles as a result of said surface charges. The structured composite can be used to produce paints having higher opacity than conventional paints containing an equivalent amount of titanium dioxide and the durability of these paints is better than a conventional paint containing a similar amount of uncoated titanium dioxide.

摘要： A process for the production of a structured composite pigmentary material in the form of a dispersion comprises mixing an aqueous dispersion of inorganic pigmentary particles and an aqueous dispersion of polyvinyl chloride (PVC) particles. The inorganic pigment particles carry a positive surface charge and the PVC particles carry a negative surface charge and the particles in the composite are held in association as a result of these charges. The inorganic pigment particles and PVC particles are mixed in the presence of a surfactant system which provides both anionic and steric stabilisation. In one embodiment the surfactant system comprises a nonionic surfactant having an HLB value greater than 12 and at least 2% by weight of an anionic surfactant with respect to the weight of PVC particl In a second embodiment the surfactant system comprises at least 2% by weight (with respect to PVC) of one of more surfactants providing anionic and steric stabilisation and being ethylene oxide condensation products having a polyoxyethylene chain with an average length of at least 8 oxyethylene units. The product is useful in paints and provides improved opacity compared to conventional pigments and improved gloss compared to known structured composite pigments.

摘要： A relight fuel flow schedule controls fuel flow to the combustor of a turbofan aeroengine during in-flight relight procedures. A first fuel ramp, whose slope decreases with increasing altitude, enables the combustor to light with minimum fuel flow for the altitude and thus helps to prevent overfueling. The fuel flow rate undergoes a step reduction, after detection of satisfactory combustion, to prevent compressor stall, but cannot drop below a predetermined level to guard against flameout. The first fuel ramp is repeated if satisfactory combustion does not occur. After a successive relight a second fuel ramp is varied from flat to positive slope depending on the ratio of the rate of change of high pressure compressor speed to a datum level in order to prevent a hung start and accelerate the engine until normal acceleration control laws takes over.

摘要： A device for identifying the presence of a specific target molecule or biomarker by the detection of a change in an electrical property includes a measurement sensor 8 comprising a semiconducting sensor structure 12 capable of conjugating with the biomarker, thus giving rise to the said change in electrical property, and an electrode system 3, 4 for conducting a signal from the device. According to the invention there is a further such sensor 9, of substantially identical form but having its sensor structure 14 already conjugated with the biomarker, or otherwise capped, e.g. using a further oligonucleotide strand, so as to act as an internal reference. When a biological sample, e.g. saliva, is applied to the electrodes, the reference enables the discounting of all environmental effects other than the biomarker.

摘要： A novel method for the production of titanium dioxide slurries having a high solids content comprises subjecting an aqueous slurry of titanium dioxide to cross-flow filtration to produce a slurry containing at least 50%, preferably 60 to 80% titanium dioxide by weight. The slurry can be washed during filtration to reduce the concentration of soluble ions. The process can produce concentrated slurries of titanium dioxide having remarkably low viscosities.
