Patent

CA 1335168

A scented extinguishing powder for ashtrays and the like is disclosed. The powder is produced by heating volcanic-origin tuff at a temperature of 600 degrees Celsius, and then suddenly cooling in water. Then it is completely dried and ground into 1mm granules, sieved and soaked in diluted alcohol. The powder is then placed in an autoclave at a temperature of up to 200 degrees Celsius and at a pressure of 10 Bars for a period of approximately two hours. After the powder is completely dried, it is poured into a tube which contains a spiral transporter whose function is to mix, by a small number of rotations, the dry powder; simultaneously, from an ultrasonic device which converts floral oil into cold vapour, the fragrance vapour is released into the tube but so that the pores of the dry granules absorb the vapour only on the surface which the spiral exposes.
