Abstract

The invention relates to a device for causing naked flames to rise rapidly and without danger. It consists of a tube (1) having an orifice (2) into which is inserted an electrical igniter with a black-powder safety fuse (black wick end) (3) on which is placed a cotton-wool flash ball (4) with magnesium. A second cotton-wool flash ball (6) without magnesium, separated (5) from the first and a third cotton-wool flash ball (9) without magnesium separated (8) from the second make it possible to cause the flame to rise between 2 and 3 metres. The device according to the invention is particularly intended for all indoor (on-stage) and public shows (spectaculars).

Description

La présente invention concerne un procédé pour faire monter haut (2m à 3m) des flammes nues sur scène fermée (Théâtre-Opéra) devant un public.The present invention relates to a method for raising high (2m to 3m) open flames on a closed stage (Theater-Opera) in front of an audience.

En principe, on utilise pour faire monter des flammes, un système dit licopode avec un appareil dit "pipe à licopode". Cet appareil nécessite une petite veilleuse, ce qui veut dire que si l'effet intervint 1h après le début du spectacle,il faut allumer la veilleuse au dernier moment. Si on peut allumer la veilleuse sans être vu du public, tout va bien, mais si on ne peut pas et que l'on est obligé de l'allumer à distance, il faut mettre de l'alcool de théâtre ou de la pâte à feu, allumer par un allumeur électrique, en espérant que l'alcool ou la pâte n'ait pas séché.In principle, a so-called licopod system is used to make the flames rise, with a device called a "licopod pipe". This device requires a small night light, which means that if the effect occurs 1 hour after the start of the show, you must light the night light at the last moment. If you can light the nightlight without being seen by the public, everything is fine, but if you can't and you have to light it from a distance, you must put on theater alcohol or batter. fire, light by an electric igniter, hoping that the alcohol or the paste has not dried.

Il faut de l'air pour projeter le produit sur la veilleuse1 ce qui nécessite une bouteille d'air et tirer un tuyau jusqu'à l'appareil. Tout dépend où l'appareil doit être mis sur scène, l'installation peut être compliquée. Il y a beaucoup de perte au niveau du produit car il en tombe beaucoup à côté. L'appareil est imposant et risque d'être vu du public. Ce système dégage une forte chaleur et peut être dangereux pour les artistes.Air is needed to spray the product onto the pilot light1 which requires an air bottle and draw a hose to the appliance. It all depends on where the device is to be put on stage, installation can be complicated. There is a lot of loss in the product because it drops a lot next to it. The device is large and may be seen by the public. This system gives off strong heat and can be dangerous for artists.

Ou alors, il y a le gaz, mais c'est dangereux dans un théâtre et, de plus, c'est interdit.Or there is gas, but it is dangerous in a theater and, moreover, it is prohibited.

Le procédé selon l'invention permet de remédier à tous ces inconvénients. Il comporte, en effet, selon une première caractéristique, un tube fermé d'un côté, avec un petit orifice du côté fermé. Dans ce tube passe par l'orifice, un allumeur électrique auquel est accroché un petit bout de .mèche noire.The method according to the invention overcomes all these drawbacks. It has, in fact, according to a first characteristic, a tube closed on one side, with a small orifice on the closed side. In this tube passes through the orifice, an electric igniter to which is hung a small piece of black wick.

Il est nécessaire d'utiliser de la ouate éclair (produit connu)
Le produit humide à l'origine doit sécher en bande et non en morceaux. Une fois le produit sec, chaque bande est coupée en deux et formée en boulettes. Trois boulettes sont placées espacées les unes des autres dans le tube. A la première boulette de ouate éclair est ajouté peu de poudre flash (magnésium) que l'on place sur l'allumeur électrique. Les deux autres boulettes sont constituées uniquement de ouate éclair.It is necessary to use flash wadding (known product)
The original moist product should dry in strips, not in pieces. Once the product is dry, each strip is cut in half and formed into pellets. Three pellets are placed spaced from each other in the tube. To the first ball of light cotton wool is added little flash powder (magnesium) which is placed on the electric igniter. The other two dumplings are made of lightning wadding only.

L'allumeur électrique est relié à une pile de faible voltage.The electric igniter is connected to a low voltage battery.

Le dessin annexé illustre l'invention.The accompanying drawing illustrates the invention.

La figure 1 représente en coupe, le procédé. Figure 1 shows in section, the process.

En référence à ce dessin, le procédé comporte un tube (1) avec un petit orifice (2) du cioté fermé, de 10 à 14 cm par 4 cm de diamètre. Un allumeur électrique (3), une courte mèche noire
accrochée à l'extrémisté,lui-même passé par l'orifice (2). Une boulette de ouate éclair avec du magnésium (4) est placée dans le 1/3 inférieur du tube sur l'allumeur électrique (3). Un espace (5) compris entre 5mm et 15mm est laissé entre la première et la deuxième boulette sans magnésium (6). La seconde boulette (6) est retenue par un adhésif double face (7). De même, un espace (8) compris entre 5mm et 15mm est laissé entre la 2ème et la troisième boulette sans magnésium (9) qui, elle aussi, est retenue par un petit bout de adhésif double face (10).With reference to this drawing, the method comprises a tube (1) with a small orifice (2) in the closed side, from 10 to 14 cm by 4 cm in diameter. An electric igniter (3), a short black wick
attached to the end, itself passed through the orifice (2). A ball of light cotton wool with magnesium (4) is placed in the lower 1/3 of the tube on the electric igniter (3). A space (5) of between 5mm and 15mm is left between the first and second pellets without magnesium (6). The second pellet (6) is retained by a double-sided adhesive (7). Similarly, a space (8) of between 5mm and 15mm is left between the 2nd and third pellets without magnesium (9) which, too, is retained by a small piece of double-sided adhesive (10).

L'explosion de la première boulette plus puissante tend à pousser la deuxième, qui eile, poussera la troisième. Cette réaction en chaîne permet de faire monter la flamme haut.The explosion of the first more powerful dumpling tends to push the second, which eile, will push the third. This chain reaction allows the flame to rise high.

Des variations qui ne sont pas illustrées peuvent être réalisées.Variations which are not illustrated may be made.

En réduisant la hauteur du tube et le diamètre et en ne mettant que deux boulettes de ouate éclair, la flamme monte alors moins haut.By reducing the height of the tube and the diameter and putting only two balls of flash wadding, the flame then rises lower.

Le procédé selon l'invention est particulièrement destiné à faire monter. des flammes nues en scène fermée simplement et sans danger devant un public. The method according to the invention is particularly intended for raising. open flames on stage closed simply and safely in front of an audience.
