Patent number: 11892374Abstract: A device for monitoring the tightness of a sealing component wherein the monitoring device has a box with a peripheral partition and a cover made of a transparent material is disclosed. The cover is connected to the peripheral partition such that the cover and the peripheral partition are able to define, with a sealing component, an inner chamber, the peripheral partition with an inner peripheral wall having a lower end equipped with an inner peripheral seal intended to be positioned against the sealing component all around the inner chamber, and an outer peripheral wall arranged outside the inner peripheral wall so as to define, between the outer peripheral wall and the inner peripheral wall, an intermediate chamber extending exclusively in the peripheral partition all around the inner chamber.Type: GrantFiled: April 15, 2020Date of Patent: February 6, 2024Assignee: GAZTRANSPORT ET TECHNIGAZInventors: Pierre Jolivet, David Hassler, Julien Glory

Patent number: 9625095Abstract: A sealed and insulating reservoir contains a pressurized cold fluid in a rigid, sealed enclosure. A fluidtight membrane is positioned to contact the cold fluid contained in the reservoir. An insulating barrier is placed between the fluidtight membrane and the internal surface of the rigid enclosure, with the insulating barrier forming a support surface to support the fluidtight membrane. A pressure balancing device is able to limit the pressure difference between a first sealed volume located inside the fluidtight membrane, and a second sealed volume located outside the fluidtight membrane. The pressure balancing device typically includes a fluid circuit having two chambers sealingly separated by a movable separator. The first chamber is linked to the first sealed volume, and the second chamber is linked to the second sealed volume. The movable separator exerts a loading force in the direction of the second chamber.Type: GrantFiled: September 27, 2013Date of Patent: April 18, 2017Assignee: GAZTRANSPORT ET TECHNIGAZInventors: Laurent Spittael, Bruno Deletre, David Lafare, Pierre Jolivet, David Hassler, Amaury Mange, Benoît Capitaine, Ali Abdallah
