Abstract: Process for the chemical treatment of lignocellulose materials, in particular of at least one piece of wood, characterized in that said materials are subjected to impregnation by a chemical agent comprising hydrocarbonaceous chains, this agent being chosen from mixed anhydrides, except for the mixed anhydride of acetic/benzoic acid, said agent being suitable for providing covalent grafting of a plurality of hydrocarbonaceous chains to said materials.

Abstract: A fixed installation is placed close to at least one aircraft parking area. The installation includes a pipe connected to the system. Said pipe is routed into a fixed base erected on the ground and then into an articulated structure. Its extremity for connection to the aircraft is mounted on a pod vertically mobile at the extremity of the articulated structure. The chassis rests on the ground by means of orientable driving wheels whose drive controls the deployment and folding of the structure. When deployed, this structure forms a bridge permitting the passage of vehicles.

Abstract: In order to carry out the refuelling of an aircraft, use is made of an installation associated with the loading bridge used for the transfer of passengers between the air terminal and the aircraft. The installation includes a retractable extension mechanism supported by the loading bridge and a deformable hose permanently connecting a pressure intake of a fuel distribution network to a coupling carried by the extension mechanism. The installation is controlled by the energy available on the loading bridge from a console. It can be partly or totally automated.
