Abstract: A device for generating a magnetic field moving in at least one field plane located in a fluid to be treated and in which the gradient of the vector product between the intensity of the magnetic field and its displacement velocity induces stereochemical deformations of the molecules of the treated fluid, which may be a limestone water or a fuel. Each field plane may have a first magnetic field generator such as a pair of coils (10, 10?) and a second magnetic field generator such as a pair of coils (12, 12?) forming an angle ? with the first generator, both being disposed at the periphery of the pipe (20) through which the fluid to be treated is flowing. At least one of the two field generators generates a magnetic field whose amplitude is variable over time so that the resultant is a magnetic field moving in the field plane having a variable amplitude and a direction moving at an angular velocity such as to obtain the highest possible gradient of the vector product.

Abstract: The invention relates to a device comprising a Laplace power generator acting on a deionizing cell provided with at least one deionizing cell comprising a first element provided with an alternate pile of membranes which are selectively ion-permeable and define concentrating chambers, deionizing chambers and a chamber on each end of the pile, a second element comprising a pile having a number of membranes equal to the first element but said membranes are electrically insulated and extend the chambers of the first element, and a third element provided with two chambers, one of them combining all concentrating chambers and end chambers, the other combining all deionizing chambers.
