Claims (8)

1. Appareil de répartition de dipoles qui sont dans une douille d'éjection (14) de manière susceptible d'être éjectés sous forme de plusieurs sections (15 à 24, 46 à 52), les sections élémentaires se composant à cette occasion chaque fois de dipoles en faisceau situés dans une enveloppe (36) et précontraints de manière centripète, caractérisé en ce que les sections (15 à 24; 46 à 52) sont de différentes longueur et que leur enveloppe se compose de feuille métallique (31 à 39; 56 à 62) mince, lisse des deux côtés, dont le nombre d'enroulement décroit dans le sens de l'éjection et en ce que la douille (14) est pourvue d'une surface intérieure polie et d'une bouche d'éjection 45).
2. Appareil selon la revendication 1, caractérisé en ce que les nombres d'enroulement des enveloppes sont de 4,2 à 1,2 respectivement de 4,5 à 0,75.
3. Appareil selon la revendication 1, caractérisé en ce qu'une section (15) sans enveloppe est disposée à la bouche (45) de la douille (14), mais toutefois avec des dipoles (10) précontraints de manière centripète, et qu'ensuite se trouvent des sections (16 à 24) à enveloppe (31 à 39).
4. Appareil selon les revendications 1 et 2, caractérisé en ce qu'en fonction du spectre de fréquences prédéterminé dans les sections (47 à 52) à dipoles (10) de même longueur, au moyen d'entailles (54) transversales à l'axe longitudinal de la douille (14), des dipoles de longueur différente (11, 12) sont contenus à côté de dipoles de longueur identique et que la profondeur d'entaille (53) est fonction du nombre de dipoles requis pour l'unité surface-fréquence la plus élevée.
5. Appareil selon la revendication 1, caractérisé en ce que la feuille de métal (31 à 39; 56 à 62) n'est déformable que de manière plastique et présente des deux côtés des surfaces à poli miroir.
6. Appareil selon la revendication 1, caractérisé en ce que la feuille de métal (31 à 39) se compose d'aluminium et présente une épaisseur d'environ 0,1 mm.
7. Appareil selon la revendication 1, caractérisé en ce que la feuille de métal (31 à 39) est en une pièce.
8. Appareil selon la revendication 1, caractérisé en ce qu'un frein à air (72) est prévu à l'extrémité libre (42) de la feuille de métal (71), au moyen de deux arêtes (75, 76) situées transversalement par rapport à la direction angulaire (77).
