    Abstract: A multi-gas microsensor assembly for simultaneously detecting carbon dioxide and oxygen in real time. According to one embodiment, the assembly comprises a non-conductive, solid substrate. A plurality of sensing electrodes, a single reference electrode, and a single counter electrode are positioned on one side of the non-conductive, solid substrate. In addition, all of the electrodes are in intimate contact with the same side of a solid-polymer electrolyte anion-exchange membrane, the solid polymer electrolyte membrane having at least one gas diffusion opening aligned with each sensing electrode. The sensor is operated in a three-electrode potentiostatic mode, in which a constant potential is maintained between the sensing and reference electrodes, and the current is measured between the sensing and counter electrodes. Control of the electrodes is achieved with a small bi-potentiostat. The design of the bi-potentiostat allows at least two different sensing electrodes to share the same counter and reference electrodes.

    Abstract: Reactive adhesives are prepared based on polyurethane compositions obtained by reacting at least one type of polyol with at least one type of diisocyanate containing at least 80 percent by weight 2,4′-diphenylmethane diisocyanate. Such adhesives are applied to a surface to be glued of at least one substrate, thermally reactivated separately in time and/or space from application of the adhesive, and then used to join together the substrates to be adhered to each other.

    Abstract: Hotmelt polyurethane adhesive compositions which are solid at room temperature and capable of being cured by moisture are obtained by combining the reaction product of a polyisocyanate and a low molecular weight polymer derived from ethylenically unsaturated monomers and containing active hydrogen groups such as hydroxyl with an isocyanate-containing polyurethane prepolymer derived from one or more polyols. The low molecular weight polymer component may, for example, be obtained by free radical polymerization of mixtures of unsaturated monocarboxylic acids, alkyl esters of unsaturated monocarboxylic acids, and/or hydroxyalkyl esters of unsaturated monocarboxylic acids.

    Abstract: Reactive hotmelt adhesives based on liquid polyether polyols and/or polyester polyols and aromatic diols with at least one diisocyanate have a very low melt viscosity and high early strength. They are particularly suitable for the bonding of substrates of poor thermal conductivity, such as foams and nonwoven materials, and heat-sensitive substrates.
