  CENTRE NATIONAL 'de RECHERCHES METALLURGIQUES, 
Dans le brevet principal, on a décrit un   procède   de contrôle des mouvements de la charge dans un four à cuve, caractérise en ce qu'on enregistre de manière continue ou   dits-   continue, tout ou partie des radiations électro-magnétiques é mises par les différentes zones de la surface de la charge, et en ce qu'on prend toute mesure appropriée pour réduire ou supprimer toute zone de la dite surface présentant une tempé

 rature anormalement élevée, la présence d'une telle zone se manifestant par un accroissement dos radiations émises à cet endroit. 



   Il existe de nombreuses façons de procéder à   l'en-   registrement de telles radiations, que ce soient des radiations omises directement par la charge, ou des radiations émises par celle-cipa réflexion de radiations incidentes, 
Dans certains cas il est intéressant de conserver l'image de tels enregistrements afin notamment de pouvoir co   trôler   l'effet des différentes mesures adoptées, sur l'état de la surface do la charge, 
Il est évident que dans dos cas   de ce   genre, c'est l'enregistrement   photographique.soit   par photographie unique ou   répétée,   soit par   cinématocraphie,   qui est le plus apte à four- nir de tels documents à caractère permanent. 



   On peut également utiliser des prises de vues   ac-     célérées   ou ralenties sans difficultés particulières, 
Dans les cas ou il n'est pas nécessaire d'obtenir des images dont les indications doivent être conservées, et ou on peut se contenter d'une connaissance instantanée et tempo- raire des phénomènes qui se passent à la surface de la charge du haut fourneau, il est avantageux d'utiliser une méthode d'observation par l'intermédiaire d'un appareil de télévision, 

 <Desc/Clms Page number 3> 

 
Cette dernière méthode.présente l'avantage non'   négligeable   de ne pas exiger la présence de l'observateur à la partie   supérieure   du haut fourneau. 



   Il est à remarquer qua tous les types d'observa- tien ou d'enregistrement des radiations   électro-magnétiques ,   plus   spécialement   des radiations visibles ou   infra-rouges    peuvent convenir pour l'application du procédé suivant l'in-   vention.

  NATIONAL CENTER for METALLURGICAL RESEARCH,
In the main patent, a method has been described for controlling the movements of the load in a shaft furnace, characterized in that all or part of the electromagnetic radiation emitted by the cells is recorded in a continuous or so-called continuous manner. different areas of the surface of the load, and in that all appropriate measures are taken to reduce or eliminate any area of said surface having a temperature

 <Desc / Clms Page number 2>

 abnormally high radiation, the presence of such an area being manifested by an increase in the radiation emitted at this place.



   There are many ways of recording such radiations, whether they are radiations directly omitted by the load, or radiations emitted by the latter by reflection of incident radiations,
In certain cases it is interesting to keep the image of such recordings in order in particular to be able to control the effect of the various measures adopted, on the state of the surface of the load,
It is evident that in such cases it is photographic recording, either by single or repeated photograph, or by cinematography, which is most apt to provide such documents of a permanent character.



   It is also possible to use accelerated or slowed down shots without any particular difficulty,
In the cases where it is not necessary to obtain images, the indications of which must be preserved, and where one can be satisfied with an instantaneous and temporary knowledge of the phenomena which occur on the surface of the top load furnace, it is advantageous to use a method of observation through a television set,

 <Desc / Clms Page number 3>

 
This last method has the significant advantage of not requiring the presence of the observer at the top of the blast furnace.



   It should be noted that all types of observation or recording of electromagnetic radiations, more especially visible or infra-red radiations, may be suitable for the application of the method according to the invention.
