Abstract: The invention relates to a mass-flow conveyor, from which falling shafts branch off in order to supply packaging machines with cigarettes. The object is to shut off the cigarette-filled falling shafts, relative to the mass flow passing through, during the standstill of the packaging machines in a way which treats the articles carefully. This is achieved by means of a blade (19), around which is guided a flexible band (17) which, on the one hand, is fastened in the region of the shaft inlet to a limiting wall (11) of the falling shaft (6), the said limiting wall being located in the feed side of the mass flow (3), and, on the other hand, is held behind the limiting wall (11) by a tension spring (22). The blade (19) can be moved obliquely upwards out of the limiting wall (11) to an opposite limiting wall (12). Located opposite the shaft inlet is a breathing compensating volume (32) of the mass flow (3), and a band roller (13) is arranged at the shaft inlet adjacently to the opposite limiting wall (12). This arrangement guarantees a smooth displacement of the articles during the shutting-off advance of the blade, during which the band continuously lifts the articles which are received by the compensating volume. <IMAGE>

Abstract: Fusible limitant le courant de court-circuit qui fonctionne selon un principe de rétroaction électronique et thermique pour obtenir une libération rapide et précise du fusible qui peut être rapidement remis à l'état initial. Selon ledit principe, on utilise une résistance (R5) non linéaire puissante dépendante de la température dans le circuit collecteur d'un transistor à effet de champ (M1) qui sert de vanne de courant et à travers lequel passe l'intégralité du courant à surveiller. Ledit circuit remplace un fusible conventionnel et peut également fonctionner comme dispositif de commande de mise en marche/arrêt de la charge. Lorsqu'un défaut survient dans la charge, le courant erroné est limité à une valeur beaucoup plus basse qu'avec un fusible conventionnel.

Abstract: On coule un dopant (76), tel que de l'antimoine, autour d'un germe monocristallin, de façon à constituer un ensemble germe-dopant (14) permettant le dopage d'un semi-conducteur en fusion (36), tel que du silicium, dans un four de tirage de cristal (34). Afin de tirer un lingot dopé, on maintient l'ensemble germe-dopant dans une partie relativement froide du four, simultanément à la fusion du semi-conducteur. Quand le bain de fusion est prêt pour le dopage, on abaisse l'ensemble germe-dopant jusqu'à une position située immédiatement au-dessus du bain. La chaleur transférée par le bain à l'ensemble germe-dopant provoque la chute du dopant depuis le germe dans le semi-conducteur en fusion sans éclabousser ni immerger le germe.
