Abstract: Sur un essuie-mains, il est possible de choisir entre un programme standard, avec lequel on libère, pour former une boucle de tissu, en premier lieu une partie de tissu non utilisée et ensuite une partie moins importante de tissu utilisée, et un programme hygiénique, avec lequel on libère uniquement une partie non utilisée. Dans les deux cas, un détecteur de mouvement contrôle si le tisssu est déplacé par une influence extérieure et, dans l'affirmative, la partie de tissu est rentrée dans l'appareil, en tant que partie utilisée, trois secondes après la fin du mouvement. Si le tissu, après être sorti, n'est pas déplacé pendant 20 secondes, il est tiré à nouveau vers l'arrière en tant que partie non utilisée. Dans les deux cas, on peut choisir des programmes économiques avec une sortie de parties de tissu plus courtes. Dans le cadre du programme standard, on peut choisir entre un programme normal, avec lequel dans un premier temps la partie de tissu utilisée est rentrée et ensuite la partie non utilisée est mise à disposition, et un programme rapide, avec lequel la sortie de la partie non utilisée s'effectue en premier lieu. En ce qui concerne le déclenchement de la sortie du tissu, on peut choisir entre un déclenchement par le détecteur de mouvement, qui détermine, à l'état de repos, les mouvements imprimés à une boucle de faible longueur, ou par un détecteur à infrarouge. Dans le programme rapide, la sortie du tissu s'effectue sans déclenchement.

The stream is dispersed by the impeller ( 16 ) to form a foam which is then densified in a settling zone ( 22 ), recovered through a spout ( 24 ) and solidified in storage containers. Means are provided to adjust the location of the mixing impeller ( 16 ) in the vessel ( 14 ) to change the depth of the settling zone ( 22 ).
