<p>The invention in its broad outline comprises elements positioned inside a safe, a security box, or an automatic dispenser which, by means of a pressure element triggered by the electric current in an electromagnetic valve, releases a flow of oxygen at a pressure of 150 atmospheres through distribution channels equipped with diffusers which contact diffusers for the colourless liquid, forming an angle of 90 degrees; this produces a partial vacuum in the channels for the colourless liquid which is sprayed in micronised form onto the edges of the bank notes, the stain on which can be perceived 60 minutes after the system has been triggered. <IMAGE></p> |
