Abstract

This process consists in subjecting the said molecules to the action of a short wavelength laser beam emitting in the violet or ultraviolet, with a power sufficient to displace the electrons shared by the outer orbital of the covalent bond, keystone of the molecule, and to cause these molecules to break up. This process is applied to the destruction of toxic gases in particular.

Description

Procédé de dislocation de molécules chimiques composées , appareil pour sa mise en. oeuvre et
application. pour neutraliser les Gaz Toxiques.Method of dislocation of compound chemical molecules, apparatus for its implementation. work and
application. to neutralize Toxic Gases.

La présente invention a pour objet la dislocationde certains composés organiques formés avec des liaisons covalences ou tout au moins à carectère covalent dominant , ces composés ayant servi dans leur synthèse et leur application à la fabrication notamment de gaz toxiques, Ll invention utilise la production de rgyom Laser pour modifier les gaz toxiques par destruction des liaisons covalentes ,clef de voute de la molécule.The subject of the present invention is the dislocation of certain organic compounds formed with covalent bonds or at least with a dominant covalent carectere, these compounds having served in their synthesis and their application to the manufacture in particular of toxic gases, The invention uses the production of rgyom Laser to modify toxic gases by destroying covalent bonds, the cornerstone of the molecule.

Ll émetteur du rayon.peut alors affecter différents aspects remplissant ce role dans diverses conditions. The beam transmitter can then affect different aspects fulfilling this role under various conditions.

Cet émetteur est conçu pour émettre un rayonnement cohérent et multidirectionnel
Parmi les formes possibles ,on citera : - pour une protection individuelle : Un arc de cercle,muni d'une poignée,emettant suivant
sa courbe
Un bouclier dwune certaine surface pouvant ètre déplacé par la personne qui s'en protège.This transmitter is designed to emit coherent and multidirectional radiation
Among the possible forms, one will quote: - for an individual protection: An arc of circle, provided with a handle, emitting following
his curve
A shield of a certain surface which can be moved by the person who protects it.

- Pour une protection de foule et/ou de lieux,un appareil de même conception mai-s volumétrique,qui,placé dans un espace y détruira les gas. - For crowd and / or places protection, a device of the same design may-volumetric, which, placed in a space will destroy the gas.

L'appareil concerne quelques rampes de lancement disposées
autour d'un masque de protection, augmentant cette protection.The device concerns some launching ramps arranged
around a protective mask, increasing this protection.

Lappa-reil est réalisé dans une source de rayons Laser en
haut dun pylonesou de pylones de différentes hauteurs pour
protéger une enceinte ou une ville ,-sous forme de 3 rampes
rotatives.Lappa-reil is produced in a laser beam source in
top of a pylon or pylons of different heights for
protect an enclosure or a city, -in the form of 3 ramps
rotary.

Le choix du rayon Laser reposera sur certains critères:
- émission par impulsion
- de radiations de courte longueur dl onde, intenses V / UV
llénergie du photon étant inversement proportionnelle à la longueur d'onde. ( violet ou ultra- violet)
- avec une cohérence spatiale lors de l'illumination dune
zone étendue.The choice of the laser beam will be based on certain criteria:
- pulse transmission
- short wavelength, intense V / UV radiation
The energy of the photon being inversely proportional to the wavelength. (purple or ultra-violet)
- with spatial coherence when illuminating a
extended area.

- avec facilité de fonctionner en continu, d'une bonne pureté spatiale. La cavité resonnante sera dans quelques cas très réduites
L'émission dirigée de photons doit déplacer les électrons
mis en commun sur l'orbitale supérieure de la liaison covalence. - with ease of continuous operation, good spatial purity. The resonant cavity will in some cases be very small
Directed emission of photons must displace electrons
pooled on the upper orbital of the covalent bond.

Rappelons l'essentiel de la Loi dl EINSTEIN : l'énergie h J d'un photon sert à extraire l'électron et lui communiquer une vitesse : h # = 1 m v 2
2 j > ,la lumiére doit avoir une fréquence supérieure à # (# = fréquence )
On a observé avec certains gaz un effet photo électrique
qui intéresse toute la masse gazeuse ( référence:livre d'atomistique de Mr. Pr. Amiel )
Dans ces conditions d'atmosphère, la dispersion du faisceau devra ètre plus longue, la puissance de 20 à
30 Watts .Le rayonnement Laser est de type à dimère ou à CO2.Recall the essentials of the EINSTEIN law: the energy h J of a photon is used to extract the electron and communicate a speed to it: h # = 1 mv 2
2 d>, the light must have a frequency greater than # (# = frequency)
A photoelectric effect has been observed with certain gases
which concerns the entire gas mass (reference: atomic book by Mr. Pr. Amiel)
In these atmospheric conditions, the beam dispersion will have to be longer, the power from 20 to
30 Watts. Laser radiation is of the dimer or CO2 type.

On admet que dans les molécules organiques ,les éléments
sont à l'état gazeux monoatomique. We admit that in organic molecules, the elements
are in the monoatomic gaseous state.

Dans une atmosphère comprenant un organophosphoré, on
pourrait envisager le calcul énergie de liaison, sachant
que :1 mole = 22, 4 , soit exprimé en molécules:
23
1 mole = 6 , 023 X 10 . nombre dtAvogadro. In an atmosphere comprising an organophosphorus, one
could consider calculating bond energy, knowing
that: 1 mole = 22.4 is expressed in molecules:
23
1 mole = 6.023 X 10. number of Avogadro.

et par litre : 6 ,02 x 10
= 0,26 10 .and per liter: 6, 02 x 10
= 0.26 10.

22 ,4
La puissance est choisie en fonction de la longueur d'onde
et sa pénétration dans l'atmosphère. 22, 4
The power is chosen according to the wavelength
and its penetration into the atmosphere.
