  • Patent number: 5722616
    Abstract: A rotary actuator (16) has an inner body (32) forming a rotor and at least one outer body (34) forming a stator. The inner body (32) and outer body (34) carry blades (40,44) arranged in an alternating manner and defining between them two series of variable volume chambers. The cross-section of the chambers and the height of the triangular blades (40,44) decreases from one end to the other, as a result of a substantially frustum-shape of the inner body (32). Such an actuator (16) can be used for controlling an aircraft rudder or control surface and it is then positioned along the articulation axis of the rudder or control surface.

  • Patent number: 5447282
    Abstract: For bringing about the attachment of a turbojet engine (10) to an aircraft tructure such as a wing (12), use is made of a non-rotary, front, central body of the engine, which is connected by a ball joint (16) to a thrust transmission member such as an air intake (14), which is itself connected to the wing (12) by a thrust transmitting system (18). In this way, the thrust (X) of the turbojet engine is transmitted to the air intake (14) along the engine longitudinal axis before being transmitted to the aircraft structure by the system (18). Therefore the casings and lines of shafts of the turbojet engine are not exposed to any bending moment, which makes it possible to optimize the performance characteristics of said engine. Moreover, it is still possible to deform the wing (12) without any risk of surging or hunting of the turbojet engine.

  • Patent number: 4355310
    Abstract: A communication system capable of continuously exchanging digital information in a well logging installation between apparatus arranged on the earth's surface and apparatus arranged in an earth borehole, interconnected by a cable. Both the surface apparatus and the downhole apparatus include a controller and a modem for sending digital command messages downhole and digital data messages uphole. The downhole apparatus also includes one or more tools which are coupled in parallel to the downhole controller via a bi-directional bus. Each tool has a universal (identical) interface adapted to recognize a specific address unique to itself and a universal address common to all interfaces. A command message with a universal address may activate all of the tools in a "free-running" mode to transmit a predetermined quantity of data in a predetermined sequence.
