Abstract: An anaerobic fermenter-decanter for the purification of residual water from the sugar industry, with recovery of methane, consists of a tank with inclined walls, with a central agitator on a vertical shaft. A flexible cover anchored by its periphery to the walls of the tank and totally submerged forms a collecting pocket for the fermentation gases. The water to be purified is introduced, after being heated to about 35 DEG , towards the bottom of the tank near the agitator. A metal collecting bell with submerged edges and with the shaft of the agitator passing axially through it is connected by its edges to a central opening of the cover. The purification yields may exceed 90%.

Abstract: To provide for the rapid vaporization of a liquid, a porous body is impregnated with the liquid. Then the liquid contained in the porous body is heated, so as to cause a rapid vaporization of the liquid in the porous body which liquid continually migrates through the porous body under the effect of its pumping and suction capabilities. The whole of the mass of liquid to be vaporized is stored in the body in impregnated form, without the presence of a permanent liquid layer. The liquid is heated directly by passing an electric current through the porous body, the density of the porous body being chosen so as to provide a liquid retention capacity allowing a variation of the energy dissipated in time to be obtained in accordance with a predetermined law which is a function of the density chosen for the porous body. Thus interchangeable porous bodies can be used having different densities and allowing different curves of variation of the energy dissipated in time to be obtained, respectively. To provide for operation in any position the liquid is introduced and stored in a liquid mass to be vaporized solely in impregnated form directly inside the porous body, without formation of a permanent liquid layer in a housing for the porous body.

Abstract: The device for compensating for a vibratory force consists in using four rotating masses (1 to 4) with parallel axes situated in the same plane P. The masses are symmetric in pairs with respect to a plane which is perpendicular to the plane P and passes through the line of force of the vibratory force F to be compensated for, and thus are contra-rotating. <??>In order to compensate for a vibratory couple, four rotating masses (15 to 18) are used, with axes (19 to 22) parallel to an axis D and symmetric in pairs with respect to this axis D, hence co-rotating. The control is provided by a device working in real time comprising especially a non-linear adaptive filter (47) of the constant-gain Kalman type.
