  Procédé pour former un film liquide et dispositif pour sa mise en   oeuvre   
 La présente invention a pour objet un procédé permettant de former un film liquide.   1l    est parfois nécessaire de former un film liquide présentant une épaisseur approximativement constante et d'une valeur donnée, par exemple pour permettre une irradiation homogène de toute la masse d'un liquide. Or, les procédés connus à ce jour consistent généralement à former une nappe liquide par ruissellement le long d'une paroi verticale ou inclinée et ne permettent pas d'obtenir un film liquide d'égale épaisseur, de sorte que l'irradiation de certaines parties est trop grande, tandis que d'autres parties du liquide sont insuffisamment irradiées.



   La présente invention comprend un procédé pour former un film liquide qui remédie aux inconvénients des procédés connus par le fait qu'on contraint le liquide à traverser un tube transparent suivant un chemin spiralé, formé par un fil enroulé à spires non jointives sur une âme coaxiale au tube.



   L'invention comprend également un dispositif pour la mise en   oeuvre    du procédé et qui se caractérise par le fait qu'il comporte un fil dont l'épaisseur est approximativement égale à l'épaisseur du film à former, enroulé sur une âme coaxiale à un tube transparent.



   Le dessin annexé illustre schématiquement et à titre d'exemple deux formes d'exécution du dispositif permettant deux mises en oeuvre particulières du procédé.



   La fig. 1 est une vue en coupe partielle d'un organe que présentent ces deux formes d'exécution.



   Les fig. 2 et 3 sont des vues schématiques de ces formes d'exécution.



   Chacune de ces formes d'exécution comporte (fig.   1)    un tube 1 en une matière transparente aux rayons à l'aide desquels on désire irradier ou traiter un liquide. Ce tube est muni d'une âme 2 en une matière résistant aux actions chimiques du liquide à traiter. Cette âme, coaxiale au tube 1, porte un fil 3, également en une matière résistant aux actions chimiques du liquide à traiter, enroulé à spires non jointives sur cette âme. Le diamètre extérieur de cet enroulement est légèrement plus petit (maximum 1 à 3/10 de mm) que le diamètre interne du tube 1.   I1    est évident que le   diàmètre    interne du tube doit être calibré avec une tolérance maxima de 1/10 mm env., de manière que l'enroulement puisse être glissé à l'intérieur du tube et tiré hors de celui-ci.

   Le diamètre du fil enroulé sur l'âme est égal à l'épaisseur de film liquide désiré.



   Lorsqu'un liquide est contraint à traverser le tube 1, muni de son âme coaxiale pourvue de son enroulement à spires non jointives,  ce liquide suit nécessairement le chemin spiralé laissé libre entre les spires non jointives.



  Ainsi, ce liquide est automatiquement mis sous la forme d'un film présentant, sur toute sa longueur, une épaisseur pratiquement constante.



     I1    suffit donc de faire en sorte que le diamètre du fil enroulé à spires non jointives présente un diamètre égal à l'épaisseur du film désiré, pour obtenir un film présentant, sur toute sa longueur, l'épaisseur désirée et nécessaire, par exemple pour traiter ce liquide par des rayons.



   La fig. 2 représente une première forme d'exécution comprenant un récipient 4, contenant une réserve de liquide à traiter, relié par une conduite 5 pourvue du dispositif décrit, à un vase récepteur 6 du liquide traité. Une source de gaz comprimé 7, reliée par une conduite 8 au récipient 4 permet de forcer le liquide contenu dans ce récipient 4 à passer par la conduite 5 pour se déverser dans le vase 6.



   Le tube 1 est soumis à des rayons émis par une source de rayons non représentée. Ainsi, le liquide traversant ce tube suit le chemin spiralé d'épaisseur constante et est soumis, pendant tout son parcours, à l'action des rayons.



  Le liquide est donc traité dans toutes ses parties de manière homogène.



   La fig. 3 représente une autre forme d'exécution d'une installation, qui comporte un récipient de réserve 9, en matière souple et élastique, de type connu, relié de manière étanche par une conduite 10, pourvue du dispositif décrit en référence à la fig. 1, à un vase récepteur - 11. Ce dernier est relié, par une conduite 12, à une pompe à vide 13, permettant de créer un vide dans le vase   1 1    et d'aspirer, à travers la conduite 10, le liquide contenu dans le récipient 9. Le récipient s'aplatissant, sous la pression atmosphérique, au fur et à mesure de sa vidange, aucun air ou autre gaz ne peut venir en contact avec le liquide à traiter.

   Cette forme d'exécution est spécialement avantageuse pour le traitement du sang par les rayons, car elle permet d'effectuer ce traitement sans aucun risque de contamination du sang par contact avec de   l'air    ou un gaz quelconque.



   Dans d'autres formes d'exécution, le tube et son âme pourraient présenter, en coupe transversale, une   section- non    circulaire, par exemple rectangulaire avec bords arrondis.

 I. Procédé pour former un film liquide, caractérisé par le fait qu'on contraint le liquide à traverser un tube transparent suivant un chemin spiralé formé par un fil enroulé à spires non jointives sur une âme coaxiale au tube.
  



  
 



  Process for forming a liquid film and device for its implementation
 The present invention relates to a method for forming a liquid film. It is sometimes necessary to form a liquid film having an approximately constant thickness and of a given value, for example to allow homogeneous irradiation of the whole mass of a liquid. However, the methods known to date generally consist in forming a liquid sheet by streaming along a vertical or inclined wall and do not make it possible to obtain a liquid film of equal thickness, so that the irradiation of certain parts is too large, while other parts of the liquid are insufficiently irradiated.



   The present invention comprises a process for forming a liquid film which overcomes the drawbacks of the known processes by the fact that the liquid is forced to pass through a transparent tube following a spiral path, formed by a wire wound with non-contiguous turns on a coaxial core. to the tube.



   The invention also comprises a device for carrying out the method and which is characterized in that it comprises a wire the thickness of which is approximately equal to the thickness of the film to be formed, wound on a core coaxial with a transparent tube.



   The appended drawing illustrates schematically and by way of example two embodiments of the device allowing two particular implementations of the method.



   Fig. 1 is a view in partial section of a member presented by these two embodiments.



   Figs. 2 and 3 are schematic views of these embodiments.



   Each of these embodiments comprises (FIG. 1) a tube 1 made of a material transparent to the rays with the aid of which it is desired to irradiate or treat a liquid. This tube is provided with a core 2 made of a material resistant to the chemical actions of the liquid to be treated. This core, coaxial with the tube 1, carries a wire 3, also made of a material resistant to the chemical actions of the liquid to be treated, wound in non-contiguous turns on this core. The outside diameter of this winding is slightly smaller (maximum 1 to 3/10 of a mm) than the inside diameter of tube 1. It is obvious that the inside diameter of the tube must be calibrated with a maximum tolerance of approx. 1/10 mm. ., so that the coil can be slipped inside the tube and pulled out of it.

   The diameter of the wire wound on the core is equal to the desired liquid film thickness.



   When a liquid is forced to pass through the tube 1, provided with its coaxial core provided with its winding with non-contiguous turns, this liquid necessarily follows the spiral path left free between the non-contiguous turns.



  Thus, this liquid is automatically put in the form of a film having, over its entire length, a practically constant thickness.



     It is therefore sufficient to ensure that the diameter of the wire wound with non-contiguous turns has a diameter equal to the thickness of the desired film, to obtain a film having, over its entire length, the desired and necessary thickness, for example for treat this liquid with rays.



   Fig. 2 shows a first embodiment comprising a container 4, containing a reserve of liquid to be treated, connected by a pipe 5 provided with the device described, to a receiving vessel 6 for the treated liquid. A source of compressed gas 7, connected by a pipe 8 to the container 4, makes it possible to force the liquid contained in this container 4 to pass through the pipe 5 to flow into the vessel 6.



   The tube 1 is subjected to rays emitted by a source of rays, not shown. Thus, the liquid passing through this tube follows the spiral path of constant thickness and is subjected, throughout its course, to the action of the rays.



  The liquid is therefore treated in all its parts in a homogeneous manner.



   Fig. 3 shows another embodiment of an installation, which comprises a reserve container 9, made of flexible and elastic material, of known type, connected in leaktight manner by a pipe 10, provided with the device described with reference to FIG. 1, to a receiver vessel - 11. The latter is connected, by a pipe 12, to a vacuum pump 13, making it possible to create a vacuum in the vessel 1 1 and to suck, through pipe 10, the liquid contained in the container 9. As the container is flattened, under atmospheric pressure, as it is emptied, no air or other gas can come into contact with the liquid to be treated.

   This embodiment is especially advantageous for the treatment of blood by rays, because it allows this treatment to be carried out without any risk of contamination of the blood by contact with air or any gas.



   In other embodiments, the tube and its core could have, in cross section, a non-circular section, for example rectangular with rounded edges.
