Definitions

  • the present invention relates to a method for marking an object in order to be able to detect it later in the event of loss or theft.
  • This marking mainly concerns art objects, precious objects and collectibles.
  • the present invention provides an original and effective solution.
  • the sense of smell is used. which is much more developed in certain mammals than in humans in a natural and / or acquired manner, so that, by their scent, these mammals may be able to trace the origin of extremely fine odors, and, d on the other hand, the specific behavioral reactions provoked in many species of mammals in response to chemical substances, called pheromones, emitted in the external environment by a congener, for example to mark the limits of its territory, to bring the sexes closer together breeding periods or to warn of a danger.
  • an odorous substance is used capable of being perceived by an animal belonging to the canidae family, such as dogs, or to the class insects, such as butterflies, cockroaches and bees.
  • an odorous substance (s) capable of being detected spontaneously by an animal (or a group of animals) is used. belonging to a given family or species.
  • pheromonl substance s
  • pheromone substance is used here, either the pheromone itself, or a substance entering into the composition thereof. We know that most pheromones are made up of more or less complex combinations of molecules.
  • pheromonales substances chosen from sexual or alarm pheromonales are used.
  • ⁇ -ionone as an odorous substance alone or in combination with at least one other odorous substance.
  • the ⁇ -ionone is detected specifically and spontaneously by the canine at extremely low thresholds, from 4.104 to 4.106 molecules per cm3, while the detection threshold for humans of this same substance is 3.1.108 molecules per cm3.
  • This type of marking does not involve any training of the animal intended for detection. As indicated above, it will be entirely possible to use the dogs normally present at customs posts and trained for drug detection.
  • an odorous substance (s) capable of being detected by an animal (or a group of animals) having undergone training is used. or a packaging for recognizing said (or said) odorous substance (s).
  • the substances will be chosen as a function of the behavioral detection threshold of the animal, which must, imperatively as has already been indicated above, be different from that of humans, which will limit the number of molecules that can be used.
  • odorous substance capable of being perceived by canids
  • the caryophylene epoxide is detected by the dog at traces 1.10 ⁇ 6 g, that is to say a volatilized amount of 10 ⁇ 12 mole / liter.
  • dogs trained for the detection of drugs will also be directly usable for the remote location of objects thus marked.
  • the quantity of odorous substance (s) can be trapped in a support which is invisibly attached by the human eye to the object to be marked. This will be the case in particular when the process must be applied to the marking of objects of the tapestry type, carpet; books, stamps and tables; furs and leathers; and furniture.
  • the quantity of odorous substance (s) in and / or on a support constituted by the object to be marked itself. This will be the case in particular when the method is applied to the marking of metallic objects such as silverware or of objects made of oxides or silicoaluminates such as ceramics, glassware and precious and semi-precious stones.
  • a film, a capillary, a cartridge, a fiber or a sponge will be used as support; preferably these elements will be synthetic in nature, such as polyethylene and the like.
  • various methods can be used to trap the odorant (s) on the support; mention may in particular be made of grafting, injection of solutions or odorous granules.
  • the mode of inclusion of the support (odor trap) in the object depends on the nature of the latter and, possibly, on the chemical characteristics of the principles used for marking.
  • Such a support may consist of an organic and / or synthetic fiber or capillary in which has (or have) been trapped said (or said) odorant substance (s); in this case, the fiber will be curled up in the trap created in the object and its length will be directly linked to the chemical characteristics of the selected signal, as well than its release time.
  • the trap could also be constituted by a solution saturated by said (or said) odorous substance (s) and having polymerized in situ, or else a molecular sieve cartridge containing said (or said) odorous substance (s) ) and stamped in the microscopic orifice, the mesh of the sieve to be chosen according to the size of the selected molecules, the volume introduced (and consequently the volume of the trap) depending on the optimal release time.
