Device for modifying on request the transparency, opacity and translucency of a glazing

摘要

Double glazing inside which a fluid is made to circulate or to stay in order to subject it to a displacement or to a chemical reaction with a view to obtaining on request an opaque or translucent appearance of the window. The invention consists in placing in the double glazing a fluid which becomes tinted, either as a result of a chemical reaction by way of an electric current or by the displacement of a colourless fluid pushed out by a coloured fluid, this occurring under the effect of a mechanical pressure.
