  "Filtre pour résorption et adsorption de   gaz;   vapeurs, odeurs et analogues" 
L'invention concerne un filtre pour la résorption ot adsorption de gaz, vapeurs, odeurs et mélangea toxiques de l'air respiré. L'invention doit notamment rendre non toxi- ques les mélanges de gaz de fumées incomplètement   brûlés,   échappés des moteurs à combustion, des turbines à gaz, des moteurs Diesel et supprimer les mauvaises odeurs des armoi- res de réfrigération, des toilettes, des chambres enfumées ou remplies de gaz. 



   On utilise déjà pour cela des cartouches de mas- ques à gaz ou des récipients, qui ne peuvent être utilisée qu'une seule fois. On a utilisé pour cela des filtres à charbon très

Il a été constaté en effet que des corps   organi-   ques, mousses hydrophiles à cellules ouvertes,

   conviennent bien à cause de leur grande capacité d'absorber ou de retenir de
