Abstract: Un système de messages vocaux pour un réseau de téléphones publics interpose un Sous-système de Traitement d'Interceptions (25) dans les connexions (22) entre les téléphones publics (11) et le bureau central (10). Un Sous-système de Traitement de Voix (16) est relié au commutateur du bureau central (14) par une jonction (17). L'appelant à un téléphone public compose un numéro de téléphone souhaité (55) qui est enregistré dans le Sous-système de Traitement d'Interceptions (25, 56). Celui-ci contrôle la connexion afin de déterminer si le téléphone appelé demeure raccroché pendant un nombre prédéterminé de tonalités d'appel ou s'il demeure occupé pendant un nombre prédéterminé de tonalités d'occupation (82). S'il n'y a pas de réponse ou si le téléphone demeure occupé, le Sous-système de Traitement d'Interceptions réduit le volume des tonalités et superpose une annonce vocale sur celles-ci qui offre le service de message vocal à l'appelant (83). Si l'appelant compose un code d'acceptation ou introduit une pièce (84), le Sous-systeme de Traitement d'Interceptions divise la connexion par fil (101), envoie un message de remerciement au téléphone de l'appelant (104) et appelle rapidement le Sous-système de Traitement de Voix (109). Lorsque celui-ci répond (114), le Sous-système de Traitement d'Interception envoie une invitation vocale au téléphone de l'appelant lui expliquant qu'à la tonalité, un message vocal pourra être déposé et que l'on tentera de transmettre celui-ci à des intervalles prédéterminés pendant une période prédéterminée (115) au moyen d'un protocole ayant des signaux d'accusé de réception à validité entrelacée depuis le Sous-système de Traitement de Voix. Si la transmission des paramètres d'appel est valide (116), le Sous-système de Traitement d'Interception rétablit la connexion par fil entre le téléphone de l'appelant et le commutateur du bureau central et le message vocal de l'appelant est transféré par le Sous-système de Traitement d'Interceptions et vers le Sous-système de Traitement de Voix où il

Abstract: Procédé pour la conversion rapide des acides organiques et alcools contenus dans des bacs de fermentation anaérobie en hydrogène et gaz carbonique, substrats précurseurs optimaux pour la production de méthane. Ce procédé prévoit d'ajouter aux bacs de fermentation des bactéries photosynthétiques, que l'on expose à une énergie de rayonnement, par exemple l'énergie solaire. On augmente ainsi la stabilité du pH du bac de fermentation afin d'en améliorer l'efficacité. Les substrats utilisés pour les bactéries photosynthétiques seront de préférence les produits des acides organiques et des déchets d'alcool des bactéries de fermentation. En culture mixte avec des bactéries méthanogènes ou en co-culture déterminée avec des bactéries méthanogènes non-acéticlastiques, les bactéries photosynthétiques peuvent faciliter la conversion des acides organiques et des alcools en méthane au prix d'un faible apport en énergie lumineuse.

Abstract: Disclosed herein is a medical tube (1) which comprises a surface-treated inner tube (2) of fluoroplastic, a metal wire (3) spirally wound round the inner tube (2), and an outer covering (4) of polyurethane placed outside the spirally wound metal wire (3), said outer covering (4) being bonded to and integral with the inner tube (2) through the interstices of the spirally wound metal wire (3). It does not collapse easily when bent, because the spirally wound metal wire (3) reinforces the tube wall. It can be bent with a smaller bending radius than the conventional one. It can be made in smaller diameter because it is possible to reduce the wall thickness without any fear of its collapsing. These advantages contribute to reducing the diameter of the inserting part of an endoscope.

Abstract: A method and device are shown for opening plastic bags (50) having a cut edge (51), over the length of which the upper bag lip (53) is to lifted off from the lower bag lip (52). The plastic bag (18) to be opened is the forwardmost and uppermost of a series of plastic bags (50) which lie one on top of the other in an imbricated formation and are detachably fastened on adhesive strips (14) running parallel to one another and perpendicularly to the respective cutting edges (51) on the undersides (54) of the plastic bags (50). Via a nozzle (28), a main airstream, generated by a blower (30), is directed onto the cut edge (51) of the forwardmost plastic bag (18), held on a support (4; 6). By means of nozzles (32), auxiliary airstreams are directed onto the lower (52) and upper (53) bag lip at a greater flow rate than that of the main airstream. Before the opening of the plastic bag (18), the said auxiliary airstreams also flow over the upper side (55) of the said bag, essentially parallel to the upper side (55). The plastic bag (18) is completely opened by the main airstream after the upper bag lip (53) has been lifted off from the lower bag lip (52), at least in certain sections, by the effect of the auxiliary airstreams. <IMAGE>

Abstract: When clipping a graphics element (2) defined by its element border (6) to a viewing window (4) having a window border (8) within which the graphics element is to be displayed, it is necessary to plot closure lines (10) along the window border between the points (EX, EN) where the element border exits and enters the viewing window. This closure line may be plotted along one of two paths between the points and along the window border. The system detects which of these paths the closure line should take. An effectively infinitely extending line from a point (P) on the window border is tested to see whether it crosses that portion of the element border outside the viewing window between the exit point and the entry point an odd or an even number of times. If it crosses an odd number of times then the closure line is plotted to pass through the predetermined point, and if it crosses an even number of times then the closure line is plotted to not pass through the predetermined point.
