Inventor: PIZZACALLA ANTHONY DOMENIC
IPC: B67D1/04
Filed: 2009-05-13
Abstract: L'invention porte sur un appareil à vanne, qui comprend un corps de vanne ayant une première entrée, une seconde entrée, une sortie, et un passage en communication avec les entrées et la sortie. Un élément de vanne disposé à l'intérieur du passage empêche une communication entre la première entrée et la seconde entrée, et, dans une première position, entre la seconde entrée et la sortie. Le corps de vanne comprend une chambre de flotteur communiquant avec la première entrée et la sortie. Un élément de flotteur disposé à l'intérieur de la chambre de flotteur est flottant et peut venir en prise de façon fonctionnelle avec l'élément de vanne. L'élément de flotteur peut être déplacé vers le haut par un liquide dans la chambre afin de permettre une communication entre la première entrée et la sortie. Lorsqu'un liquide provenant de la première entrée est épuisé, l'élément de flotteur s'abaisse de façon à sceller étanchement la première entrée vis-à-vis de la sortie. L'élément de vanne se déplace vers une seconde position, de façon à permettre ainsi à la seconde entrée d'être en communication avec la sortie pour distribuer un liquide à partir de la seconde source.

IPC: C04B18/02
Filed: 2010-09-23
Abstract: The present invention provides combustion products of hydrocarbon fuels and controlled amounts of metal oxide strength enhancing materials. The combustion products are useful as additives to cementitious materials. A hydrocarbon fuel such as coal is introduced into a combustion chamber (12) and selected amounts of materials comprising CaO, SiO2 and Al2O3 are also introduced into and/or downstream from the chamber (12). The hydrocarbon fuel undergoes combustion while the metal oxide strength enhancing materials react with each other and/or the ash or other reaction products of the hydrocarbon fuel. The combustion products have been found to significantly increase compressive strengths of cements such as Portland cement. A reduction in SO2 emission levels also results from the introduction of the metal oxide strength enhancing materials into the combustion process.

Abstract: A system for automated checking of data content includes content checkers (208) to (214) arranged in parallel and connected between an input sub-system (204) and an output sub- system (216). The content checkers (208) to (214) check different data formats. Incoming data from an external computer system (202) is passed by the input sub-system (204) to the checkers (208) to (214), which report check results to both input and output sub-systems (204) and (216). From the four check results, the input sub-system (204) judges the data's acceptability for forwarding to a sensitive computer system (218). Unacceptable data is discarded; acceptable data passes to the output sub-system (216), which also judges the data's acceptability from the four check results. The output sub-system (216) only receives such data if the check results are all positive or if the input sub-system (204) malfunctions: in the latter case the check results are not all positive, and the output sub-system (216) will not forward the data unless it also malfunctions. The decision to forward data is therefore split between the input and output sub-systems (206) and (216).
