Abstract: The invention relates to an installation for producing oxygen of high purity, which is advantageously installed in a transportable container (21), comprising: an upstream pressure-swing-adsorption (PSA) device (A1) containing a zeolite sieve; a downstream PSA device (A2) containing a carbonaceous sieve; in a loop between the two devices, a permeation device (P) capable of separating oxygen form argon; and a medium-pressure oxygen compressor (20). The invention is used for producing oxygen of high purity on-site, typically in isolated locations.

Abstract: A gas generator assembly, which is especially suited to both transportable and on-board oxygen generators, with at least one adsorbent and a buffer tank to store product gas separated from a feed gas mixture. In order to make the assembly squat and compact, the buffer tank may be of an annular or quadruple U shaped configuration. Such a buffer tank configuration may also provide the assembly with improved structural and protective attributes.

Abstract: The invention relates to a blade for a turbine, the blade being fitted with a dovetail root to fix it into a compartment of a turbine disk, the blade being fitted with an internal air cooling circuit comprising air inlets located on the blade dovetail root and facing the compartment, and air outlets. The blade dovetail root is fitted with a device capable of homogenising the pressure and temperature of cooling air entering the air inlets.

Abstract: The gas generator assembly, for generating gas by separation using adsorption in at least one adsorber (3A, 3B), includes a buffer tank (4) for the product gas having at least one part, typically in the shape of a U, forming an open internal space in which at least one part of the adsorber is placed in a compact arrangement with improved strength and mechanical robustness.

Abstract: The invention relates to a blade (11) for a turbine, the blade being fitted with a dovetail root (13) to fix it into a compartment (14) of a turbine disk (12), the blade being fitted with an internal air cooling circuit comprising air inlet means (15) located on the blade dovetail root and facing the compartment, and air outlet means. The blade dovetail root (13) is fitted with means (20) capable of homogenising the pressure and temperature of cooling air entering the air inlet means.
