Title: Incineration residue treatment process and apparatus
IPC: B01J2/12
Filed: 1989-06-19
Abstract: Residue (20) produced by incineration of commercial, industrial or municipal waste is treated on-site at the point of generation or storage. Moist residue, such as incinerator bottom ash, is mixed in a multi-segment rotary drum (68) with a heavy metals treatment agent (46) in a first section (70) of the drum (68). An aggregation agent is added to the mixture, and the mixture separates under the shearing force imposed by the rotating drum (68) into individual pieces which are rolled into balls (78). A cementitious coating material (54) is added to coat the balls (78), and the coated balls (80) are classified by size. The classified coated balls (80) are conveyed to a bagging plant (154), where they are packaged in flexible containers (172) formed from material selected to retard water loss, and tagged (186) with identifying information. Toxic contaminants such as cadmium, lead and mercury are immobilized in the cured balls, which can be used as construction aggregate. Leaching of heavy metals from the incinerator residue is strongly inhibited by the process.

Abstract: On peut utiliser un interféromètre (et/ou un ensemble d'interféromètres) d'onde matérielle d'atome (et/ou molécule) neutre, comme détecteur inertiel et/ou de gravité ultra-sensible. Une paire d'interféromètres d'énergies et/ou de masses différentes peuvent procéder à des mesures indépendantes simultanées de rotation et d'accélération. Des interféromètres ayant des trajectoires suivant une configuration en huit constituent un gradiomètre gravitationnel. On utilise des réseaux de diffraction comme fractionneurs de faisceaux. Lesdits réseaux peuvent se composer d'ouvertures (S1, S2, G1, G2, G3, G4, G5, G6) se trouvant dans une feuille de matière solide, des faisceaux laser (97, 99, 101) à ondes stationnaires presque résonnantes, ou des facettes (179) de cristaux. La courbure de la trajectoire due à l'accélération et à la rotation est annulée par des gradients de champs magnétiques et/ou électriques produisant une lévitation effective d'atomes lents. On utilise un système de rétroaction maintenant une phase d'interféromètre nulle, et dont le signal d'erreur produit les signaux d'effet inertiel.

IPC: G05D3/12
Filed: 1991-05-15
Abstract: Un système de commande de la constante de temps d'accélération/décélérétion pour un robot est destiné à commander le fonctionnement d'un robot tout en donnant à la constante de temps d'accélération/décélération d'un servomoteur une valeur optimisée pour chaque bloc. Une vitesse d'arrivée est déterminée à partir d'une valeur de déplacement d'un bloc (S1-S4). Un couple de sortie (Tmax) du servomoteur est déterminé à partir de cette vitesse d'arrivée (S5), et un couple d'effort statique (Twn) est soustrait de ce couple de sortie (Tmax) pour donner un couple d'accélération (Tan) (S6). Une accélération (an) est obtenue à partir de ce couple d'accélération (Tan), puis une inertie d'effort du servomoteur (S7), ainsi qu'une constante de temps d'accélération/décélération, (τ) sont déterminés à partir de cette accélération (an) (S8). On peut ainsi déterminer une constante de temps d'accélération/décélération optimisée.

Filed: 1991-05-01
Abstract: Système, procédé et appareil servant à commander, via un calcul de déplacement vers l'avant à commande en boucle fermée, la position et l'orientation de la plate-forme mobile d'un mécanisme parallèle. Ladite plate-forme mobile est supportée au-dessus d'une plate-forme de base par une pluralité de bras parallèles de support tels que des vérins à déplacement linéaire. Les dimensions de la plate-forme de base et de la plate-forme mobile, ainsi que les longueurs des bras de support, sont fournies à un système de commande qui calcule au moins une solution (51) de déplacement vers l'avant à commande en boucle fermée, de la géométrie du polyèdre (un octaèdre pour les modes d'exécution décrits) formé par la plate-forme mobile, la plate-forme de base, et les bras de support. Le système de commande détermine la position et l'orientation finales de la plate-forme mobile en éliminant les racines imaginaires des solutions en boucle fermée et les racines qui produiraient des trajectoires discontinues pour la plate-forme mobile. Un nouveau mécanisme (Fig. 12) spécial parallèle 6-6 est également décrit. Le système de commande permet de commander, d'une nouvelle manière, des plate-formes Stewart connues 3-3 ou 6-3, il permet également de commander le nouveau mécanisme parallèle 6-6 particulier. Ce mécanisme parallèle 6-6 particulier se distingue d'un mécanisme 6-6 courant par le fait qu'il peut se réduire géométriquement à un octaèdre, et qu'il possède alors une géométrie simple, même si ses bras comprennent des connexions distinctes. L'invention concerne également un procédé de réduction du nouveau mécanisme parallèle 6-6 particulier en une plate-forme Stewart équivalente, qui est alors commandée par le système de commande de déplacement vers l'avant à commande en boucle fermée, décrit ci-dessus.
