"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:
1 ) Possibilité d'augmenter à l'infini la puissance de la source lumineuse sans craindre les inconvénients résultant de la chaleur..
2 ) Béduction de la partie non utilisable de la glace.

"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

, the curved parabolic reflector and the determined focus.
According to the arrangement shown in FIG. 1, the wool source is placed behind the lens a and the rays are reflected by the reflector g, possibly passing through a capacitor such as 6, on the faces c 'of the prismatic cavity c d' where they August referred to the sides b 'of the parts or signs engraved b.
According to the Mostrean embodiment FIG. 2, la; ¯; la- ce it is eolairée by its upper part. 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.

3) Possibility of atolating a device which is exactly applied against a wall, backdrop or similar surface.
