    Abstract: A kit, for analyzing and monitoring a parameter of a reaction in a reaction chamber, includes: a hollow tube fastened by its ends to the reaction chamber; and a capsule provided with a sensor and guided along the hollow tube via a magnetized magnetic piston disposed in the hollow tube and controlled by a guide device. The hollow tube imposes a predetermined trajectory on the capsule to maintain the capsule at a distance from any mobile member to prevent the capsule from damage. The hollow tube can extend over the entire depth of the reaction medium to allow measurements over the entire depth of the medium.

  • Publication number: 20120260962
    Abstract: An electric generator based on a thermoelectric effect includes at least a heat source, a heat dissipator and a thermoelectric converter provided with at least two areas respectively in contact with the heat source and the heat dissipator. The heat source is the center of an exothermic chemical reaction, such as the catalytic combustion of hydrogen. The heat dissipator is the center of an endothermic chemical reaction, at least one product of which forms one of the reagents of the exothermic chemical reaction. Once it is formed by the heat dissipator, said product is then directed towards the input of the heat source in order to react there. The endothermic chemical reaction is more particularly a steam reforming reaction for methanol.
