    摘要： Linked polyamine cyclic compounds of general formula V - R - A - R' - W where V and W are independently cyclic polyamine moieties having from 9 to 32 ring members and 3 to 8 amine nitrogens and having either one or more aromatic rings fused thereto or a heteroatom other than nitrogen incorporated in the ring, A is an aliphatic or aromatic moiety and R and R' are each a linking chain, possess improved partition coefficients at biologically relevant pH compared to known compounds, and possess high anti-HIV activity.

    摘要： Apparatus for use in an engine exhaust system contains
       a catalyst (A) for the treatment of the exhaust gas in order to combat air pollution, and
       a non-catalytic heater (B,C) up-stream of the catalyst (A), to reduce the time it takes the catalyst (A) to reach its effective reaction temperature, the heater (B,C) having at least 15 heated channels per square cm, as measured at right angles to the gas flow through them, the heated channels being less than 1.0 cm in length, so that in operation the gas passes through the channels, and is thereby heated before it reaches the catalyst (A), the heater (B,C) being such that the heated gas leaving the channels has at least to some extent turbulent flow.

    摘要： A catalyst comprising catalytic material on a support, the catalytic material comprising platinum, and the support consisting essentially of at least one of zirconia, tin oxide and titania, which catalyst contains less than 400ppm of chlorine atoms based on the weight of catalytic material plus support, is useful for reducing the content of nitrogen oxides in a flue gas containing them, oxygen and 5-3000ppm by volume of sulphur dioxide by admixing ammonia with the flue gas and passing the mixture over the catalyst.
