Abrégé
The present invention relates to a calorimeter for studying a chemical reaction continuously, comprising: at least one reaction chamber through which move reactants and one or more reaction products, resulting from the reaction between these reactants; and a thermopile comprising a plurality of alternating measurement thermojunctions and reference thermojunctions. According to the invention, said or each reaction chamber and said thermopile are in contact with each other so as to make it possible, on the one hand, for the measurement thermojunctions to be in thermal contact with the reaction product(s) and, on the other hand, for the reference thermojunctions to be in thermal contact with one or both of the reactants taken individually.

ELECTRODYNAMIC TRANSDUCER INCLUDING A DOME WITH A FERROFLUID SUSPENSION
The invention relates to an electrodynamic transducer (1) having a dome membrane (2) comprising an electrodynamic motor with a coil (6) which is supported by a mandrel (3) that is solidly connected to the membrane which is suspended from a frame (7). The aforementioned coil is disposed in a gap in which it can move and which is defined at the centre by an inner magnetic structure (4) and at the periphery by an outer magnetic structure (5). According to the invention, the suspension does not contain a peripheral suspension nor an inner suspension. The inventive transducer comprises at least two means (11) for confining the magnetic field in the gap in order to form at least two tiered ferrofluidic seals (12, 13, 14) in the gap using a ferromagnetic liquid, such as at least to guide the coil and to form a pneumatic seal between the front and rear faces of the membrane, at least one of said ferrofluidic seals being continuous. The invention is suitable for loudspeakers.
The invention relates to an electrodynamic transducer including a frame and containing at least one electric coil (2) which is placed in a static magnetic field and which can move about a rest position in a vertical free space. The aforementioned coil(s) is wound around and fixed to a mandrel (12) and a return means is used to return the coil-bearing mandrel to the rest position in the absence of an external bias, said straight cylinder defining an inner volume and an outer volume. According to the invention, the magnetic field is produced by outer and inner magnetic structures which each comprise at least one fixed permanent magnet in the form of a ring. The motor does not contain any ferromagnetic or magnetic part between the outer volume and the inner volume. Moreover, at least the part of the frame that is used to fix the magnets is made form a non-ferromagnetic and non-magnetic material. The ratio R of the inductance value Lp of the coil when at rest and blocked in the transducer to the inductance value Ll of the same coil when free and isolated in the space is between 0.9 and 1.1 in the useful frequency band of the transducer. Numerous implementation variants are disclosed in the invention.

Abrégé
The invention concerns supports or receptacles for solubilized or suspended biological entities whereof the walls are made of plastics surface-treated by an electromagnetic plasma followed by a polymer deposition. It can be in the form of tubes or multiple-well plates. It provides among other things the possibility of storing, transferring and performing reactions in the context of microassays of biological entities, more particularly the prion protein, with enhanced sensitivity.
