Title: Slurry hydrocarbon synthesis with downcomer fed product filtration
Inventor: LEVINESS STEPHEN C
IPC: C07C9/14
Filed: 1998-05-05
Abstract: Hydrocarbon liquid products are filtered and removed from a three phase hydrocarbon synthesis slurry comprising gas bubbles and particulate catalyst solids in a hydrocarbon liquid, by circulating the slurry through a gas disengaging downcomer immersed in the slurry to a filtration zone external or internal of the reactor, and then back into the slurry in the reactor. The gas disengagement densifies the slurry which is passed across the filtration surface under high flow conditions, to reduce solids build up on the filter as filter cake. Circulation through the filtration zone occurs by gravity and hydrostatics due to slurry density differences. The downcomer may also be a gas and solids reducing downcomer.

Abstract: L'invention concerne une méthode de détection du plomb sur une surface cible, dont la peau humaine, au moyen d'un système d'essuie-mains et d'un test chimique par ions rhodizonate ou sulfure. On frotte ou on essuie une surface à tester avec un essuie-mains pour recueillir les résidus se trouvant à la surface de l'essuie-mains. On solubilise ensuite toute particule de plomb recueillie sur l'essuie-mains, en utilisant une solution aqueuse acide. On fait ensuite réagir, le plomb solubilisé éventuellement recueilli, avec des ions rhodizinate ou sulfure pour faire apparaître une couleur caractéristique. Si du plomb solubilisé est présent, le traitement aux ions rhodizinate entraîne l'apparition d'une couleur allant du rose au rouge; le traitement aux ions sulfure entraîne l'apparition d'une couleur allant du marron au noir. Cette méthode est particulièrement utile dans la détection de la présence de plomb sur la peau et à vérifier l'efficacité du lavage des mains et de la suppression de toute trace de plomb sur la peau de personnes exposées. Cette méthode est également particulièrement utile dans l'évaluation sur place de la présence de plomb et de l'efficacité de son retrait sur le lieu de travail, à la maison, dans les écoles et dans des environnements similaires ainsi que l'exposition au plomb desdites personnes dans lesdits environnements.

Filed: 2000-08-08
Abstract: The present invention relates to a method for transporting data between a data transmitting network element and a data receiving network element via a point-to-point connection in a communications network. This communications network comprises at least one transmitting network element and at least one data receiving network element.      An Internet Protocol Control Protocol request for a service level of sending data is sent to the data receiving element by the data transmitting element. This Internet Protocol Control Protocol request is received by the data receiving element. The data receiving element then determines a service level based on a predetermined criterion and formulates an Internet Protocol Control Protocol propose of the service level that can be provided to the data sending element. Subsequently the Internet Protocol Control Protocol propose of the service level is sent towards the data transmitting element. The Internet Protocol Control Protocol propose including the service level propose in its turn is received by the data transmitting element and used for sending data towards the data receiving element.     It is also possible to initiate the (re-)negotiation by the data receiving network element, by sending Internet Protocol Control Protocol messages to the data transmitting element.      As an alternative the data transmitting element is able to notice that a provided service level is not satisfying and that it formulates another request for a service level that is satisfying for the data transmitting element. Re-negotiation of an existing service level specification is also possible by sending Internet Protocol Control Protocol messages requesting another service level specification.
