Abstract: The present disclosure provides a system for opening and closing, in a substantially longitudinal direction, at least one hatch of a landing gear bay of an aircraft. In particular, the system includes: a proximal guide rod and a distal guide rod, each having a first end pivotably attachable to the hatch, and a second end pivotably attachable to a stationary inner structure of the gear bay, and arranged such as to form a deformable parallelogram hinge; and at least one drive rod having a first end that is pivotably attachable to the hatch, and a second end that is pivotably attachable to a landing gear leg.

Abstract: A system for depositing cells on an analysis plate, the cells being contained in a cell suspension including a fixing agent and the cells, included, for receiving the suspension, a chamber (5) which is positioned above the analysis plate and whose base is open and extends opposite a cell depositing zone of the plate and a material for absorbing the fixing agent placed around the chamber and the depositing zone of the plate. The chamber is mounted so as to be able to be moved between a first position in abutment against the analysis plate in order to allow the cells to be deposited on the depositing zone of the plate via decantation and a second position remote from this analysis plate in order to place the chamber in a fluid relationship with the absorption material in order to allow this material to absorb the fixing agent.

Abstract: An aircraft structure includes a skin (28) that is reinforced in two directions: by a first family of stiffeners called stringers (30) that are arranged in the longitudinal direction of the aircraft, and by a second family of stiffeners called frames (32) that are arranged in planes that are perpendicular to the longitudinal direction and that ensure the taking up of orbital forces, characterized in that at least one frame (32) has a hollow cross-section that is delimited by a closed profile, produced for a given cross-section in a single piece, of which one portion is in contact with the skin.

Abstract: A system for analyzing a cell suspension includes at least one well for decanting (1) the suspension and elements (2, 3) for analyzing the cell deposits at the bottom of the well over time during the decanting, so as to allow an analysis of the cells by strata (T1, T2, T3) as a function of their rate of decantation.

Abstract: A windscreen frame, and a method of production for a windscreen frame, designed to hold a windscreen in an opening in a wall, the frame including at least one upper horizontal frame section element, at least one lower horizontal frame section element and at least one vertical mounting, characterized in that it is a single unit in composite material.
