Patent CA-2463052-A1 (CA)
Inventor: BAILEY GARY L
IPC: E21B33/12
Filed: 2001-10-03
Abstract: L'invention concerne un appareil et un procédé permettant le montage étanche d'un premier élément tubulaire en un emplacement fixe par rapport à un second élément tubulaire concentrique. L'élément tubulaire intérieur est configuré de manière à présenter un enfoncement annulaire creux dans la paroi du tube à l'emplacement du matériau d'étanchéité, de telle sorte que la paroi de l'élément tubulaire intérieur pénètre dans le passage cylindrique à l'intérieur du tube. Sur la surface extérieure du premier élément tubulaire, l'enfoncement est rempli d'un fluide partiellement compressible. L'enfoncement annulaire et le fluide partiellement compressible sont alors recouverts d'un manchon malléable/ductile. La mise en place de la garniture étanche nécessite de positionner l'élément tubulaire intérieur dans l'élément tubulaire extérieur et de déplacer le tube intérieur longitudinalement de façon que l'enfoncement annulaire recouvert soit positionné à l'emplacement d'étanchéité voulue. Pour rendre opérante la garniture d'étanchéité, il est nécessaire de diriger un dispositif de déplacement cylindrique à l'intérieur de l'élément tubulaire intérieur vers le point où le dispositif de déplacement rencontre l'intrusion de la paroi du tube intérieur provoquée par l'enfoncement annulaire. Le dispositif de déplacement est forcé au travers de l'intrusion annulaire et repousse vers l'extérieur la paroi du tube intérieur de manière à éliminer efficacement l'enfoncement annulaire tout en alignant la paroi cylindrique du tube afin de permettre le passage du dispositif de déplacement. En même temps, le fluide partiellement compressible se répand sous pression vers l'extérieur, sous le recouvrement malléable/ductile, de telle façon qu'il pénètre dans ledit espace annulaire entre le tube intérieur et le tube extérieur. Cette expansion sollicite le recouvrement malléable/ductile de manière à l'amener en contact avec l'élément tubulaire extérieur, ce contact augmentant dans la zone en question, du fait que ledit fluide partiellement compressible continue d'être pressurisé par le déplacement, dû au mouvement du dispositif de déplacement, de l'élément tubulaire intérieur. Le fluide partiellement compressible présente une énergie résiduelle suffisante pour maintenir l'élément d'étanchéité en contact intime avec la paroi du tubage extérieur.

Abstract: A dual mode high voltage power supply circuit using an external high voltage (Vpp) connected through an internal high voltage switch (30) which determine s whether the memory blocks of a non-volatile memory circuit (46) are programm ed in a first mode from an internal high voltage charge pump (20) or are programmed in a second mode from an external high voltage power supply connected in parallel to the internal high voltage charge pump. When the dua l mode high voltage power supply circuit is operating in the first mode using only its internal change pump (20) high voltage (Vm) , it operates in a low power, low-speed mode, programming only one or two bits at a time but allowi ng the charge pump area on the die to be small. When operating in the second mode, in which the external power supply high voltage is available, eight or more bits can be written to at the same time, thus allowing a fast programmi ng mode without the need for increasing the size of the internal charge pump, thus eliminating the additional space and cost required to increase the die area.

Abstract: L'invention concerne un système et un procédé de gazéification qui comprend un dispositif de combustion pulsatoire communiquant avec une canalisation pour fluides afin de produire un flux gazeux ayant une valeur calorifique ou combustible. Le dispositif de combustion pulsatoire fonctionne dans des conditions sub-stoechiométriques de façon que la combustion et le reformage à la vapeur interviennent toutes deux dans la canalisation pour fluides. Le dispositif de combustion pulsatoire produit également un flux de combustion pulsatoire et une onde de pression acoustique. L'onde de pression acoustique permet de provoquer l'agglomération de particules contenues dans le flux de combustion afin d'en faciliter l'évacuation. Dans un mode de réalisation, un agent capteur de soufre est injecté dans la canalisation pour fluides, non seulement pour supprimer le soufre présent dans le flux de combustion mais également pour faciliter l'agglomération des particules. Finalement, on obtient un flux gazeux contenant de l'hydrogène susceptible d'être utilisé dans divers procédés, notamment dans la production d'électricité.
