Abstract: A system for analyzing containment integrity of a containment system includes data storage for inspection data and characteristic data and a data evaluation processor for evaluating the inspection data. A data acquisition system is used for periodically obtaining wall thicknesses of selected components in the containment system. After data validation, the actual wall thick­nesses are stored as the inspection data in the data storage. The data evaluation processor analyzes the present pipe wall integrity in light of stress calculated from the characteristic data including operational conditions and material properties. In addition, the data evaluation processor analyzes the trend in change of wall thickness to forecast future wall thicknesses.

Abstract: Concentrated solutions of inorganic hydroxylammonium salts can safely be produced in a process for concentrating a dilute solution of an inorganic hydroxylammonium salt by contact with a membrane having a sorption side and a desorption side. The process comprises contacting the dilute solution with the sorption side of a membrane, which is substantially permeable to the solvent and substantially impermeable to the solute of the solution, to sorb the solvent and permit the solvent to flow through the membrane to the desorption side. Desorbing the solvent from the desorption side of the membrane. 
     Highly concentrated aqueous solutions of hydroxylammonium salts which are heat sensitive are produced by the novel process of the invention which does not require directly heating the solution and is substantially free of hazards.

Abstract: L'invention concerne un procédé d'élaboration et de construction consistant à assembler facilement diverses structures d'art à partir d'une série de segments (1) alternant avec des unités de raccordement (2). Notamment pour des structures en forme d'arc de voûte, des éléments de segments s'adaptant par glissement aux raccordements (2) constituent, par l'intermédiaire de forces de contact, un mécanisme auto-porteur pendant et après le processus de construction. Par tensionnage d'au moins un câble (5) passant dans la structure, cette dernière est maintenue fermement par compression. Outre le fait que le tensionnage assure à la structure une capacité de port de charge par neutralisation des contraintes de traction de pliage interne, ledit tensionnage du câble constitue, par l'intermédiaire des raccordements (2), un mécanisme de jointure efficace entre les segments simplifiant l'assemblage et le désassemblage de la structure. Comme la compression, plutôt que la flexion, est le mode principal de charge interne d'éléments segmentaires, les matériaux qui autrement sont inadéquats tels que des solives en bois de faible diamètre deviennent des matériaux structurels utiles.

Abstract: Un séparateur à gravité pour séparer des particules plus lourdes de substances résiduaires plus légères comporte un empilement de tabliers (4) montés en vue d'un mouvement oscillatoire résonant à l'intérieur d'un cadre de support (1). Un moteur (9) fait osciller les tabliers à leur fréquence de résonance tandis qu'un système de distribution (6) fournit à la surface des tabliers une charge se présentant sous la forme d'une boue. A mesure que les secousses se poursuivent, les particules plus lourdes à l'intérieur de la boue sont graduellement séparées des particules plus légères. Une séparation optimale est assurée par un système de régulation qui, s'il y a lieu, modifie automatiquement l'amplitude d'oscillation et/ou la synchronisation des étages, en cours de séparation, par exemple en réponse aux signaux produits par des détecteurs qui mesurent la fréquence d'oscillation et l'énergie consommée.

Abstract: Procédé de libération d'un ingrédient actif d'une capsule. L'ingrédient actif est encapsulé dans une matière qui est sensible au sel et l'intégrité de la capsule est maintenue en gardant la capsule dans une solution aqueuse dont la concentration en sel est supérieure à la concentration à laquelle la matière sensible au sel est soluble. Lorsque l'on désire libérer l'ingrédient actif, l'enveloppe sensible au sel de la capsule est dissoute dans la solution aqueuse où la capsule est gardée pour libérer l'ingrédient actif en diminuant la concentration en sel de la solution. En fonction de la matière particulière sensible au sel que l'on choisit pour l'enveloppe, la libération de l'ingrédient actif peut être facilitée en changeant la température de la solution aqueuse.
