Abstract: The invention concerns a method consisting in the following steps: The waste gas (6) is catalytically (1) hydrolyzed to form a hydrolyzed gas (15) containing H2S and SO2, and free of COS and CS2. After cooling (17), the hydrolyzed gas is introduced in one (2a) of two CLAUS catalytic zones (2a, 2b) mounted parallel, the other catalytic zone (2b) being for regenerating, then cooling. The regeneration is carried out, in open circuit, with a gas stream (19, 36) drawn from the gas (15) before it is cooled (17), the regeneration gas effluent (24b) being re-injected (29, 20) into the gas (15), between drawing (19) and cooling (17). The cooling of the reactor (2b) is carried out, in open circuit, with a gas stream (11, 36) drawn from the waste gas (6), the cooling gas effluent (24b) being re-introduced (29, 13) into the waste gas (6) between drawing (11) and heating (8).

Abstract: L'invention concerne un dispositif d'échappement multicanal de turbomachine, du type multicanal à entré annulaire, comprenant une enveloppe extérieure de forme générale symétrique par rapport à un axe et au moins une séparation interne définissant plusieurs canaux sensiblement concentriques pour l'écoulement du flux d'échappement, un revêtement absorbant capable d'absorber une partie de l'énergie acoustique générée par l'écoulement est prévu sur au moins une surface de la séparation interne et/ou sur une surface interne de l'enveloppe extérieure. L'épaisseur du revêtement absorbant est adaptée sur la longueur du dispositif d'échappement pour optimiser l'écoulement dans les différents canaux en maintenant la diffusion progressive et en évitant les décollements au voisinage des surfaces immobiles. Grâce à cette disposition, la signature acoustique de la turbomachine est grandement réduite puisqu'il devient possible de bénéficier de l'augmentation de surface traitée acoustiquement due à la présence des séparations internes.

Abstract: Seeds of Brassica's and related species (Crucifers), having increased dormancy coupled with greater tolerance to stresses associated with fall seeding in long winter climates, are produced by treatment with solutions of sugars and/or polyols, for a specified period, typically 10 to 70h at room termperature, followed by air drying to ambient moisture content. Dormancy is generally released on overwintering, moist chilling or hydration-dehydration-rehydration or as a function of increasing temperature or time or a combination of the preceding. Treated seeds afford better emergence over a larger seeding window for fall sown seeds of Brassicas and related species thus increasing the attractiveness of this practice for these crops.

Abstract: L'invention concerne une composition biocide pour le traitement de l'eau, un appareil de traitement de l'eau, ainsi qu'un procédé de traitement de l'eau en vue de réduire la teneur en agents pathogènes. La composition renferme des sources d'ions métaux, à savoir, cuivre, zinc et argent, dans une matrice polymère réticulée. On mentionne comme exemples de ces sources d'ions, le sulfate de cuivre, le sulfate de zinc et le nitrate d'argent. Un exemple de matrice polymère réticulée est le chitosane réticulé qui sert également à clarifier l'eau tout en libérant à la longue les ions métaux. Le produit est facile à fabriquer et permet d'utiliser moins de stérilisant halogéné et moins d'ions cuivre, réduisant ainsi la probabilité de coloration. Le produit présente de bonnes propriétés à la fois bactéricides et algicides, en dépit de faibles teneurs en ions cuivre et en chlore.

Title: Method and system for delivering and metering liquid sterilant
Inventor: NGUYEN NICK NGOC
IPC: B65D83/00
Filed: 2001-02-05
Granted: 2012-04-24
Abstract: A system and a method for delivering and metering a fixed volume of liquid, such as a liquid sterilant from a container into a vaporization system. The method for the delivering system includes the steps of sensing a requirement for additional liquid sterilant, determining whether the liquid sterilant to be added is acceptable for use, and delivering the liquid sterilant from a container into an accumulator. The method of metering the liquid sterilant into the vaporization system includes creating a vacuum in a chamber connected to the vaporizer and delivering the liquid sterilant into a vaporizer while continually sensing the flow of the delivery. The metering system maintains a slow, controlled flow in order to achieve efficient vaporization of the liquid sterilant and to provide accurate sensing of the gas/liquid interface.
