Title: Procede de regeneration de solutions d'halogenures acides
Inventor: WASMUND BERT
IPC: C23G1/36
Filed: 2001-10-31
Abstract: La présente invention concerne un procédé de régénération d'un agent de lixiviation à l'halogénure acide aqueux présent dans une liqueur lixiviante à l'halogénure métallisé aqueux épuisé. Le procédé consiste à introduire dans un lit fluidisé ou un four de grillage à pulvérisation, un combustible hydrocarboné, un gaz oxydant enrichi en oxygène et la liqueur lixiviante à l'halogénure métallisé aqueux; à pyrohydrolyser la liqueur lixiviante à l'halogénure métallisé aqueux par combustion du combustible hydrocarboné avec le gaz oxydant enrichi en oxygène pour produire une fraction gazeuse contenant de l'halogénure acide et une fraction solide contenant de l'oxyde métallique; à séparer la fraction gazeuse de la fraction solide; à récupérer l'énergie thermique de la fraction gazeuse contenant l'halogénure acide et à absorber la fraction gazeuse dans de l'eau pour produire l'agent lixiviant à l'halogénure acide aqueux. Le gaz oxydant enrichi en oxygène présente une teneur en oxygène qui est supérieure à environ 21 pour cent en volume, qui est de préférence supérieure à environ 50 pour cent en volume et qui est plus préférablement supérieure à environ 80 pour cent en volume et qui est encore plus préférablement supérieure à environ 90 pour cent en volume. De préférence, l'halogénure métallisé aqueux est du chlorure de fer (II) ou du chlorure de nickel. En dépit des coûts élevés associés au gaz oxydant enrichi en oxygène par rapport à l'air, ce procédé peut être mis en oeuvre de manière plus économique et plus efficace qu'une pyrohydrolyse par grillage à l'air équivalente et produit une liqueur lixiviante à l'halogénure aqueux à concentration plus élevée, qui est préférée dans les procédés métallurgiques tels que l'extraction par solvant et la lixiviation des matières solides.

Abstract: An automated device monitors moisture content in exterior sheathing of a building for detecting moisture intrusion into the sheathing walls. A plurality of moisture sensors are embedded in selected exterior walls of the building behind the cladding and are adapted to provide signals representative of the moisture content in the walls at each of the selected locations. A control unit is operatively connected with each of the plurality of moisture sensors for generating an alarm signal when at least one of the signals representative of the moisture content in the plurality of walls is indicative of a moisture content in excess of a predetermined threshold value. Each moisture sensor is preferably in the form of a pair of spaced apart elongate conductive probe members having a substantial portion thereof from a lead end embedded into a substrate of the exterior building walls, and a connection end extending outwardly from the first wall for enabling electrical connection of each moisture sensor to the control unit.

Title: Method and system for characterization of online behavior
Inventor: TARQUINI MAUREEN MENDICK
IPC: G06Q30/02
Filed: 2002-09-20
Abstract: Data about computer network traffic is collected as user website visit recording sessions. The data captured is analyzed and organized with sufficient level of detail or granularity to determine a single request from a server. Each data request is analyzed to determine if it comes from a server with which an ongoing end user interaction or open site visit is occuring. If not, a new site visit is created as a general proposition. If the data request is part of an open site visit, then the time is compared to the time of the last interaction and if the interval is sufficiently small, the data request is treated as a continuation of the visit. If the interval is large, a new site visit is created.
