Description

  

  Procédé d'obtention de radiations ultraviolettes et lumineuses  de composition choisie.    La présente     invention    comprend un pro  cédé d'obtention de radiations     ultraviolettes     et lumineuses de composition choisie, selon la  revendication I du brevet principal et qui  est     caractérisé    en<B>ce</B> que l'excitation .du  champ est assurée par     induction    électro  magnétique à l'aide d'une     source    de courant  à haute fréquence et d'un enroulement par  couru par     ce    courant.  



  Elle comprend également un dispositif  pour la mise en     oeuvre    de -ce procédé, suivant  la revendication II -du brevet principal, et  qui est caractérisé en<B>ce</B> que     l'enceinte    pré  sente un logement pénétrant à l'intérieur -de  celle-ci et dans lequel est disposé un noyau  en substance magnétique, un enroulement re  lié par ses extrémités à une source de -cou  rant à haute     fréquence    étant disposé de ma  nière à entourer     -ce    noyau.  



  On a déjà indiqué, au brevet     principal,          l'importance    capitale d'une forte     densité    -de    courant pour obtenir .des     radiations    ultra  violettes et lumineuses de composition va  riable     choisie.    Lorsqu'on agit par induction  électromagnétique sardes gaz rares, tels que  le krypton et le xénon,

   cette forte densité est  évidemment     fonction        croissante    du taux de la  variation du .champ magnétique en chaque  point de     l'enceinte.    Ce taux peut être     atteint     avec des courants -de fréquence ne dépassant  pas celle pouvant être produite industrielle  ment par un alternateur, soit 30.000 pé  riodes par seconde environ, à condition -d'a  dopter des dispositions permettant -de réa  liser un champ magnétique d'amplitude suf  fisante.  



  Le dessin annexé représente, à titre  d'exemple, deux formes     -d'exécution    du dis  positif pour la mise en     oeuvre    -du procédé.  



  Sur la     fig.    1, on a muni le ballon 1 -d'un  manchon cylindrique 2 qui pénètre à l'inté  rieur et forme logement étanche pour un en-           roulement    3, dont les bornes 4 sont reliées à  une source de     -courant    à haute     fréquence    telle  qu'un     alternateur,    un triode générateur,     etc.     L'expérience prouve qu'on obtient ainsi l'ef  fet désiré dans     -d'excellentes    conditions.

   Ces       -conditions    sont d'ailleurs encore améliorées  en disposant, .à l'intérieur de l'enroulement 3,  un noyau en     substance        magnétique    5, formé,  par exemple, par des bandes de tôles     minces     (placées     radialement)    ou par des fils de très  petit diamètre, -dans le but de diminuer,  comme connu, les pertes par courants de  Foucault.

   A ce     point    d e vue,     il    est avanta  geux de     constituer    ledit noyau magnétique  par -du métal à l'état pulvérulent, dont les  grains sont agglomérés par une substance       isolante    convenable;     l'expérience    montre en  effet qu'on peut atteindre ainsi, aux fré  quences déjà de l'ordre     radiotélégraphique,     une perméabilité apparente d'au moins 7 à 8,  les pertes .demeurant très acceptables.  



  Sur la     fig.    2, l'enroulement inducteur 3  est     bobiné    à l'extérieur -de l'ampoule 1,     ce     qui peut présenter     certains    avantages -cons  tructifs. Même avec     cette    .disposition, l'ad  jonction d'un noyau ferromagnétique 5 dans  le manchon 2, de     préférence    en fer pulvéru  lent,     conserve    généralement un intérêt con  sidérable, ainsi qu'on le vérifie expérimenta  lement. Bien entendu, la longueur et le dia  mètre     optima    sont à     déterminer    suivant -cha  que     application.     



  Quant à la courbe ,du courant magnétisant  en fonction -du temps, elle peut différer       éventuellement    de la     sinusoïde    et     affecter     notamment une forme     pointue,    grâce à la       présence    d'harmoniques, d'amplitude     accrue     au besoin artificiellement par tous moyens       connus    (saturation magnétique,     ete.).     



  Comme dans le brevet principal, les     Dis-          positifs        décrits    comprennent -des moyens pour  produire     .une    excitation atteignant une     grande     intensité au moins -de manière instantanée,  lesdits moyens     d'excitation    de l'atmosphère  enclose par     l'enceinte    étant séparés d'au  moins une paroi de l'enceinte     servant    à l'ir  radiation par une     distance    suffisante pour  que ladite paroi soit pratiquement soustraite    à.

   l'action     excitatrice    et demeure, de     ee    fait,  sans l'intervention de moyens     auxiliaires    .de  refroidissement, à une température suffi  samment basse pour pouvoir être appliquée  sur une partie à traiter.



  Process for obtaining ultraviolet and light radiation of selected composition. The present invention comprises a process for obtaining ultraviolet and light radiations of selected composition, according to claim I of the main patent and which is characterized in <B> this </B> that the excitation of the field is ensured by induction electromagnetic using a source of high frequency current and a winding by run by this current.



  It also comprises a device for the implementation of -this method, according to claim II -of the main patent, and which is characterized in <B> this </B> that the enclosure has a housing penetrating inside. -of the latter and in which is disposed a core of magnetic substance, a winding re linked by its ends to a source of high-frequency -cou rant being disposed in such a way as to surround this core.



  The main patent has already indicated the capital importance of a high current density in order to obtain ultra violet and luminous radiations of variable composition chosen. When acting by electromagnetic induction Sardinian noble gases, such as krypton and xenon,

   this high density is obviously an increasing function of the rate of variation of the magnetic field at each point of the enclosure. This rate can be reached with frequency currents not exceeding that which can be produced industrially by an alternator, i.e. approximately 30,000 periods per second, on condition that provisions are adopted which allow the creation of a magnetic field of suf ficient amplitude.



  The appended drawing represents, by way of example, two forms of execution of the positive device for the implementation of the method.



  In fig. 1, the balloon 1 was provided with a cylindrical sleeve 2 which penetrates inside and forms a sealed housing for a winding 3, the terminals 4 of which are connected to a high-frequency current source such as '' an alternator, a generator triode, etc. Experience has shown that the desired effect is thus obtained under excellent conditions.

   These -conditions are also further improved by arranging, inside the winding 3, a core of magnetic substance 5, formed, for example, by strips of thin sheets (placed radially) or by wires of very small diameter, -in order to reduce, as known, eddy current losses.

   From this point of view, it is advantageous to constitute said magnetic core by -du metal in the pulverulent state, the grains of which are agglomerated by a suitable insulating substance; experience shows that it is thus possible to achieve, at frequencies already of the radiotelegraph order, an apparent permeability of at least 7 to 8, the losses remaining very acceptable.



  In fig. 2, the inductor winding 3 is wound on the outside of the bulb 1, which may have certain advantages -cons tructifs. Even with this arrangement, the addition of a ferromagnetic core 5 in the sleeve 2, preferably of slow powdered iron, generally retains considerable interest, as has been verified by experiment. Of course, the optimum length and diameter are to be determined according to each application.



  As for the curve of the magnetizing current as a function of time, it may possibly differ from the sinusoid and in particular affect a pointed shape, thanks to the presence of harmonics, of amplitude increased if necessary artificially by any known means (magnetic saturation ,     summer.).



  As in the main patent, the devices described comprise -means for producing an excitation reaching a high intensity at least instantaneously, said means for excitation of the atmosphere enclosed by the enclosure being separated from at least one wall of the enclosure serving for ir radiation by a sufficient distance so that said wall is practically subtracted from.

   the exciting action and remains, therefore, without the intervention of auxiliary cooling means, at a sufficiently low temperature to be able to be applied to a part to be treated.
