    摘要： A composite structure comprising:

    (a) at least one layer comprising at least one uncured or partly cured thermoset resin precursor;
    (b) in contact therewith, at least one layer comprising at least one amorphous thermoplast, said precursor and said amorphous thermoplast having mutual solubility at a temperature between ambient and thermoset cure temperature; and
    (c) reinforcing fibre present in either or both of said layers and/or between them. The relative thicknesses of layers (a) and (b) are preferably such that, on curing or further curing, layer (b) merges sufficiently into layer (a) to leave distinguishable thermoplast under 5% of total initial thickness. The thermoplast is preferably a polyarylether containing sulphone groups in its chain.

    摘要： A polyamide article for use in contact with antifreeze compositions at elevated temperatures wherein the article is formed of a reinforced composition comprising a polyamide selected from nylon 66, nylon 6 and nylon 610 or copolymers thereof,from 10 to 60% by weight of reinforcing filler and from 0.1 to 10%, preferably 0.25 to 5% by weight of a copolymer formed from ethylenically unsaturated monomers and having functional groups extending from the polymer chain capable of reaction with the end groups of the polyamide polymer wherein the copolymer contains up to 50 mole % of residues obtained from ethylenically unsaturated monomers containing functional groups. The functional groups are preferably carboxylic acid or carboxylic acid anhydride groups. The articles include radiator end tanks and water pump bodies and impellers.

    摘要： A pyroelectric device comprising a pyroelectric thermometer (1) e.g. in the form of a tube or a bowl, and which thermometer is in operative contact with a relatively thick mass of catalytic material (5). The device can be used as a gas detector by selecting a catalytic material which is capable of bringing about chemical reaction of the gas to be detected with resultant change in temperature. A particular application is its use as a personal carbon monoxide dosimeter. The device may also be used as a detector based on biological reactions e.g. in the detection of urea using the immobilised enzyme urease as catalyst.
