    摘要： A curable coating composition comprising: (a) a silicate, such as sodium silicate, potassium silicate or lithium silicate; (b) a phosphate, such calcium phosphate, magnesium phosphate or sodium phosphate; and (c) a metal oxide, such as magnesium oxide, aluminum (III) oxide, scandium (III) oxide, yttrium (III) oxide, or zirconium oxide. Such curable coating compositions may be used as non-thermochromic (tailored based on expected operating environment) thermal control coating compositions for application to spacecraft and components thereof. As an alternative metal oxide component, for use in lower temperature applications, or in applications for which thermochromism at elevated temperatures is not a concern, the metal oxide may comprise zinc oxide. Also provided is a curable coating composition comprising: (a) a silicate (e.g. as above); (b) a phosphate (e.g. as above); and (c) a metal sulphate, such as a barium sulphate. Cured coatings are also provided, as are thermal control coatings, thermal control paints, and processes for making coated substrates.

    摘要： This invention relates to a method and apparatus for thermochemically processing material, and in particular relates to the torrefaction of organic material such as biomass, in particular to improve the energy content of the material, the method involving enclosing the material in a reactor which is then evacuated by means of a fluid driven vacuum pump to establish an oxygen free environment within the reactor, heating the material to above 200° C. to liberate process by-products such as volatile gases and/or oils, extracting the liberated volatile gases and/or oils from the enclosure and entraining same within the fluid driving the vacuum pump.

    摘要： The present invention is concerned with a hollow fibre membrane for use in a Membrane Supported Biofilm Reactor (MSBR) or the like, the hollow fibre membrane comprising a substantially cylindrical sidewall defining an internal lumen from which gas can permeate through the sidewall, and characterised in that at least a part of an outer surface of the fibre membrane is engineered to define at least one biofilm retaining region which acts to retain a quantity of biofilm therein, in particular when the fibre membrane is subjected to a high sheer biofilm control event, such as experienced during a reactor cleaning cycle, for removing excess biofilm in order to prevent clogging of the reactor.

    摘要： A method of assessing biofilm thickness in a membrane supported biofilm reactor (MSBR) of the type comprising a lumen containing a gas phase, a liquid phase, and a gas permeable membrane providing an interface between the gas and liquid phases, the method comprising the steps of charging the lumen with an inert gas, closing the lumen to establish an initial elevated pressure in the lumen, measuring the rate of change of pressure within the lumen, and correlating the rate of change of pressure (dP/dt) with biofilm thickness. The step of correlating dP/dt with biofilm thickness involves correlating dP/dt with the rate of diffusion of the inert gas (dn/dt), correlating dn/dt with an overall mass transfer coefficient (K), correlating K with the mass transfer coefficient of the biofilm (kB), and correlating kB with the biofilm thickness. Also described is a membrane supported biofilm reactor (MSBR) of the type comprising a gas permeable membrane providing an interface between a lumen containing a gas phase, and a liquid phase, characterized in that the MSBR comprises means for flushing the lumen with an inert gas, means for closing and re-opening the lumen, and means for detecting intra-membrane pressure within the lumen. The means for detecting intra-membrane pressure is provided by a pressure transducer.

    摘要： A self-cleaning optical system for the transmission or reflection of light to and/or from a process region comprises a liquid bath and a transparent or reflective optical component continuously rotatable about a non-vertical axis so that a lower part of the component continuously rotates through the bath. When the component emerges from the bath, a coating of the liquid remains thereon which forms a substantially uniform film on at least a part of the component through which the light is transmitted or from which the light is reflected.
