les usagers.

  
- Les différentes solutions proposées à ce jour présentent des inconvénients tout aussi patents :
- perturbations prolongées du trafic par suite de la lenteur des opérations (application et séchage des produits);
- perturbations répétées par les renouvellements fréquents de marques prématurément effacées.
- Des améliorations aux procédés déjà utilisés ont été recherchées en réduisant ces inconvénients :

  
1. d'une part, par accélération des opérations,

  
 <EMI ID=2.1> 

  
1.L'accélération des opérations peut évidemment être obtenue non seulement :

  
a. par une mécanisation des opérations.

  
Des solutions particulières de mécanisation sont présentées dans de nombreux brevets belges ; par exemple :

  
le 698.263 (composants montés sur chassis automobile)

  
le 764.657 (composants montés sur chariot)

  
le 751.278 (qui propose une machine particulière) et

  
le 787.730 (un dispositif pour le traçage de lignes continues et discontinues au moyen de cames commandées électriquement)

  
b. mais encore par un choix judicieux des matériaux et des procédés de leur mise en oeuvre.

  
- les matériaux les plus divers :
- Matières thermoplastiques (brevet belge 800.705) ; polyes- <EMI ID=3.1>

- Résines polycétoniques à charges dures (brevet belge
787.521).
- Soufre pulvérisable (brevet belge 709.685).
- Pigments (polyoépine) pour la coloration de masses chargées.
- Perles de verre ou granulés réfléchaissants etc...
- sont actuellement utilisés et mis en oeuvre sous forme de :
peintures (brevet belge 701.299), bandes, rubans adhésifs  <EMI ID=4.1>  sation au pistolet atomiseur (brevet belge 708.549)... dontles plus rapides (collage de bandes) donnent en général les résultats les plus médiocres au point de vue durabilité ; les plus sûrs à cet égard (coloration localisée dans la masse du substrat - brevet belge 750.719) étant en général ceux dont la mise en oeuvre est la plus difficile (coffrage) et la plus lente.

  
2. Concernant l'amélioration de la durabilité ; compte tenu des

  
 <EMI ID=5.1> 

  
avec les vitesses), on pourra également agir sur les deux facteurs:
produits employés et conditions de leur emploi :

  
La nature des produits fixant leur résistance a l'érosion et  l'écrasement ; les modalités de leur application conditionnent

  
 <EMI ID=6.1> 

  
rechercher l'augmentation par une préparation préalable des surfaces : sablage, meulage (brevet belge 698.263), projection de matières adhésives (brevet belge 708.549),, application d'une

  
 <EMI ID=7.1>  <EMI ID=8.1> 

  
une antinomie ; l'amélioration d'un des facteurs - rapidité des opérations - ne s'obtenant qu'au détriment de l'autre - durabilité des résultats et vice-versa.

  
Le but de la présente invention est d'obtenir, rapidement,

  
 <EMI ID=9.1> 

  
ser les produits les plus divers, sous forme pulvérulente, et susceptible d'être exécuté mécaniquement par des moyens montés sur châssis automobile. Procédé caractérisé en ce que la projection des matériaux pulvérulents sur les surfaces s'effectue au moyen

rables à un transfert dans le domaine particulier du Génie Civil que constitue le marquage des routes.

  
C'est ainsi que des essais fructueux ont pu être faits au

  
 <EMI ID=13.1> 

  
marques obtenues sont pratiquement aussi indélébiles que si le produit avait été incorporé dans la masse du substrat (adhérences de 600 à 800 kg/cm2).

Enfin, les torches plasma de projection (exemple torches

users.

  
- The various solutions proposed to date have equally obvious drawbacks:
- prolonged traffic disruptions as a result of slow operations (application and drying of products);
- repeated disturbances by frequent renewals of prematurely erased marks.
- Improvements to the processes already used have been sought by reducing these drawbacks:

  
1.on the one hand, by speeding up operations,

  
 <EMI ID = 2.1>

  
1.Acceleration of operations can obviously be achieved not only:

  
at. by mechanization of operations.

  
Particular mechanization solutions are presented in numerous Belgian patents; for example :

  
698.263 (components mounted on automobile chassis)

  
764.657 (components mounted on cart)

  
the 751.278 (which offers a specific machine) and

  
787.730 (a device for tracing continuous and discontinuous lines by means of electrically controlled cams)

  
b. but also by a judicious choice of materials and of the methods of their implementation.

  
- the most diverse materials:
- Thermoplastic materials (Belgian patent 800,705); polyes- <EMI ID = 3.1>

  
French 112.142).

  
- Polyketonic resins with hard fillers (Belgian patent
787.521).
- Sprayable sulfur (Belgian patent 709,685).
- Pigments (polyoepin) for coloring charged masses.
- Glass beads or reflective granules etc ...
- are currently used and implemented in the form of:
paints (Belgian patent 701,299), tapes, adhesive tapes <EMI ID = 4.1> spray gun spraying (Belgian patent 708,549) ... the fastest of which (sticking of tapes) generally give the poorest results in terms of durability ; the safest in this regard (localized coloration in the bulk of the substrate - Belgian patent 750,719) being generally those whose implementation is the most difficult (formwork) and the slowest.

  
2. Regarding improving sustainability; take in account the

with the speeds), we can also act on the two factors:
products used and conditions of their use:

  
The nature of the products fixing their resistance to erosion and crushing; the modalities of their application condition

seek the increase by a preliminary preparation of surfaces: sanding, grinding (Belgian patent 698.263), projection of adhesive materials (Belgian patent 708.549), application of a

  
 <EMI ID = 7.1> <EMI ID = 8.1>

  
an antinomy; the improvement of one of the factors - speed of operations - only obtained to the detriment of the other - sustainability of results and vice versa.

  
The aim of the present invention is to obtain, rapidly,

  
 <EMI ID = 9.1>

  
ser the most diverse products, in powder form, and capable of being executed mechanically by means mounted on an automobile frame. Process characterized in that the projection of the pulverulent materials on the surfaces is carried out by means of

rables to a transfer in the particular field of Civil Engineering which constitutes the marking of the roads.

  
This is how fruitful tests have been made at

  
 <EMI ID = 13.1>

  
marks obtained are practically as indelible as if the product had been incorporated into the mass of the substrate (adhesions of 600 to 800 kg / cm2).

Finally, plasma projection torches (example torches
