Abstract: A device for the alignment of a laser beam amplification system comprises at least measuring means and alignment templates positioned instead of filtering hole plates of the amplification system, the alignment templates having holes whose centers have substantially the same spatial positions as the centers of the filtering holes, certain template holes being provided with reference sights offset in an angular way with respect to one another, the tips of these sights being pointed towards the center of the holes, the measuring means defining, by sighting at the end of the amplification system, the divergences between the focusing points of the beam in the holes, merged at a single point, and the tips of the sights, their angular positions enabling them to be assigned to their respective holes, the positions of elements of the amplification system being then controlled as a function of the measurements of divergences.

Abstract: A method for clarification and concentration of grape musts. Harvested and picked-up and crushed grapes are placed in a vinification vat, from which comes a must. The must then passes on to an apparatus where the solid phase and the liquid phase of the must are separated; and then the liquid phase is introduced into a flotation apparatus where it is clarified. The clarified must is then conveyed to a vat connected to a reverse osmosis concentration loop.
