Abstract: The invention relates to a document case for receiving a large number of standardized format documents including at least two first flaps articulated relative to each other, the documents being inserted separately into overlapping pockets with an offset, their openings being parallel to the articulation axis of the flaps so that the documents are arranged in a stepped manner in order to expose a visible uncovered edge thereof. In case of two adjacent flaps, the steps are arranged with the same insertion direction, the highest document of one flap being adjacent to the lowest document of the other flap so that when the two flaps are folded on each other, the two series of steps are interleaved in order to reduce the thickness. Modes of application include wallets, multifunction diaries and document briefcases.

Abstract: A jettisonable means comprises means with a travelling-wave tube for emitting electromagnetic waves. It forms part of an assembly having external power supply means for supplying the filament of the travelling-wave tube. The external power supply means temporarily supplies the filament of the travelling-wave tube to heat it to its nominal temperature before jettisoning, whilst, at the moment of jettisoning, the external power supply means are disconnected. This enables a temperature appropriate to the operation of the travelling-wave tube to be provided temporarily, after the jettisoning.

Abstract: The present invention relates to a method and device for temporarily enlarging the opening or hatch area of a structural frame of an aircraft. The invention proposes a fixture of smaller dimensions than the structural girder which is able to replace the latter temporarily during certain periods, in particular during loading and unloading of cargo. The invention finds an application in the fitting out of a transport aircraft.
