  "PERFECTIONNEMENTS AUX   DISPOSITIFS   D'ENSEIGNES DIURNES   ET   LUMINEUSES" 
On a déjà   proposé un   système et des dispositifs d'ensei- gnes diurnes et lumineuses utilisant la réfraction, sur les parties gravées plus ou moins profondément d'une glace, des rayons lumineux émis par une ou plusieurs lampes logées dans l'épaisseur de cette glace. 



   La présente invention a pour but de remédier à différents inconvénients du système décrit ci-dessus et en particulier elle vise à une meilleure utilisation des rayons lumineux émis par la ou les lampes utilisées, lesquelles pourront être, en outre, de beaucoup plus forte intensité. 



   L'amélioration est réalisée par   l'emploi   de prismes, avec ou sans condensateur, disposés comme il convient, tel que le mon- trant par exemple les Figs. 1 et 2 du dessin schématique annexé, dans lequel :   . 1 le

   Selon la disposition montrée en Fig. 1 , la source la-   mineuse   est disposée à l'arrière de la glace a et les rayons sont réfléchis par le réflecteur g, en travenant   éventuelle-   ment un condensateur tel que 6, sur les faces c' de la cavité prismatique c d'où ils août renvoyés   sur   les faces b' des par- ties ou signes gravés b. 



   Suivant le mode de   réalisation   mostréen Fig. 2, la   ;¯;la-   ce il est éolairée par sa partie   supérieure .     Dans   ce cas, la source lamineuse consiste, par exemple, en une série de lam- pes f dont les rayons sontrenvoyés sur les dessins ou carac- tères gravés par l'entremise du   réflecteur   g, du   condensateur   e et du prisme   ,     lesquels   se présentent,   ;le   préférence, sur toute la longueur du panneau ou plaque a, 
Les avantages de ces dispositions peuvent de   rester     comme   suit:

  "IMPROVEMENTS TO DAY AND LUMINOUS SIGN SYSTEMS"
A system and devices for daytime and luminous signs have already been proposed, using the refraction, on the more or less deeply engraved parts of a crystal, of the light rays emitted by one or more lamps housed in the thickness of this glass. ice.



   The object of the present invention is to remedy various drawbacks of the system described above and in particular it aims at better use of the light rays emitted by the lamp (s) used, which may, moreover, be of much higher intensity.



   The improvement is achieved by the use of prisms, with or without capacitor, arranged as appropriate, as shown for example in Figs. 1 and 2 of the attached schematic drawing, in which:. 1 the

In this case, the laminating source consists, for example, of a series of lamps f, the rays of which are reflected on the designs or characters engraved through the reflector g, the capacitor e and the prism, which are presented ,; preferably, over the entire length of the panel or plate a,
The advantages of these provisions may remain as follows:

     1) Possibility of infinitely increasing the power of the light source without fear of the inconveniences resulting from the heat.



   2) Reduction of the unusable part of the ice.

R E S U M E . ABSTRACT . L'invention consiste en des perfectionnements apportés aux dispositifs r'enseignes diurnes et lumineuses dans les- quels la réfraction des rayons lumineux, omis par une ou plusieurs lampes logées dans l'épaisseur d'une glace, est utilisée ur des parties gravées ou en relief de cette glace, pour former des signes, figures ou caractères. The invention consists of improvements made to daytime and light display devices in which the refraction of light rays, omitted by one or more lamps housed in the thickness of a glass, is used in engraved parts or in relief of this ice, to form signs, figures or characters. Selon l'invention, et en vue d'obtenir une Meilleure utilisation des rayons émis, tout en emplayant des lampes de beaucoup plus forte intensité, les dites lampes sont disposées, en combinaison avec des réflecteurs appropriés, soit à l'ar- rière, soit à la partie supérieure de la glace ou du panneau de verre portant les signes, figures ou caractères gravés de manière à renvoyer les rayons lumineux vers des prismes à faces argentées ou non, en combinaison ou non avec des conden- satears appropriés, les dits prismes étant prévus de toute manière convenable par rapport à la glace, mais s'étendant de préférence sur la longueur de celle-ci, According to the invention, and in order to obtain better use of the rays emitted, while using lamps of much higher intensity, said lamps are arranged, in combination with suitable reflectors, either at the rear, either at the top of the mirror or of the glass panel bearing the signs, figures or characters engraved so as to return the light rays towards prisms with silver faces or not, in combination or not with appropriate condensers, the said prisms being provided in any suitable manner with respect to the ice, but preferably extending over the length of the latter, ou se présentant sous forme de cavités prismatiques gravées dans la face de la dite glace opposée à celle présentant les signes ou caractères gravés à éclairer. or in the form of prismatic cavities engraved in the face of said crystal opposite to that having the engraved signs or characters to be illuminated.
