Abstract: A sonar device intended to be towed by a surface ship and includes a tow cable and a set of at least one towed device, comprising a towed body, intended to be towed by the surface ship via the tow cable, the towed body being elongate along a longitudinal axis from a first longitudinal end of the towed body as far as a second longitudinal end of the towed body, the towed body incorporating a first linear acoustic antenna comprising a plurality of electroacoustic transducers substantially aligned along the longitudinal axis, the towed device being configured and connected to the tow cable in such a way that the towed body is able, when it is being towed and is fully submerged, to exhibit an orientation the longitudinal axis extends substantially along a vertical axis defined by the force of gravity, at least one towed body of the set of towed bodies being connected to the tow cable by a first hanger and a second hanger of substantially the same length, a first end of the first hanger and a first end of the seco

Abstract: A handling device includes a winch comprising a frame, intended to be attached to a structure of the surface vessel and a first drum capable of turning relative to the frame about a first rotation axis and an assembly comprising at least one second drum which surrounds the first drum and is capable of turning relative to the frame about a second rotation axis substantially parallel to the first rotation axis, the winch being capable of being in a decoupled state wherein the first drum and the second drum are rotationally decoupled about the first rotation axis and the second rotation axis so as to allow a traction cable to be wound around the first drum during a first winding step wherein the first drum is rotated about the first axis, the second drum being capable of being in an open state wherein the second drum has a receiving opening that a towed body is capable of passing through in order to enter the interior of the space that surrounds the first drum and that is surrounded by the second drum, the winch

Abstract: A slip ring for optical fibers includes a first part and a second part that is able to rotate with respect to the first part, the slip ring comprising at least one data transmission channel comprising an optical/electrical converter for transforming an optical signal conveyed by an optical fiber into a first electrical signal, at least one optical emitter, receiving the first electrical signal so as to emit a light beam, at least one optical detector for detecting the light beam and for transforming it into a second electrical signal, the emitter being contained in the first part and the detector being contained in the second part, or vice versa, and an electrical/optical converter to which the second electrical signal is transmitted such that the electrical/optical converter generates another optical signal intended to be conveyed on another optical fiber.

Abstract: Embodiments of the present invention relate to a linear submersible body including a plurality of rigid segments that are articulated and can adopt relative to one another an orientation making it possible to form a rectilinear body, or a curved body of which the radius of curvature is adapted to the drum of the winch onto which it is wound. The segments are associated with couplers and configured so that a vertical rectilinear posture is naturally obtained when the device is totally submerged and towed by the ship, while the curved posture is obtained naturally by the winding of the device onto the winch. Embodiments of the invention apply to the production of linear and vertical transmitting acoustic antennas.

Abstract: Embodiments of the present invention relate to the undersea mechanics of ship-towed linear bodies which preferably are towed in a vertical position and which, at rest, are designed to be stored on the drum of a winch. The linear submersible body is capable of adopting a rectilinear configuration in a vertical position when it is towed at a total immersion depth and of adopting a curved configuration at rest, having a radius of curvature allowing it to be wound onto the drum of a winch. The device according to the invention includes a plurality of rigid segments that are articulated and can adopt relative to one another an orientation making it possible to form a rectilinear body or a curved body, of which the radius of curvature is adapted to the drum of the winch onto which it is wound.

Abstract: The present invention relates to an inking blade configuration for an ink feeding device of a rotary press, which includes a carrier beam provided at the ink duct. The inking blade is composed of segments, which are accommodated in a side-by-side configuration on the carrier element and which are adjustable relatively to a roller that dips into the ink duct, and the individual inking blade segments are connected by connecting elements to the carrier element. Provision is made underneath the connecting elements (8) in the contact region (9) of the contact surfaces (11, 12) of segments (2) and of the carrier beam (5) for a form-locking connection (13), which prevents a relative movement between the segments (2) and the carrier beam (5).
