  • Patent number: 11371613
    Abstract: The invention relates to a ring seal which comprises a main body capable of implementing a seal by static contact relative to a first cylindrical element, and a first circumferential lip capable of engaging by friction with a cylindrical surface of a second cylindrical element, said cylindrical elements being substantially coaxial and mounted so as to pivot relative to one another. The main body comprises a front surface configured to be in axial contact with a front surface of the first cylindrical element, the main body comprising a second circumferential lip radially opposite the first circumferential lip and capable of being in radial contact with a cylindrical surface of the first cylindrical element.

  • Patent number: 11104407
    Abstract: The invention relates to the field of shipbuilding and more specifically to the screw propeller for a pod drive of a vessel, particularly an ice-going vessel, providing movement both ahead and astern in icy conditions where the ice is traversable, while also providing steering for the vessel, and to a pod drive comprising said screw propeller. To reduce the weight, and consequently the cost, of the pod drive, the screw propeller comprises a propeller hub, made so that it can be rigidly attached to the conical tailpiece of the propeller shaft, and screw propeller blades, each comprising a blade foil and a blade flange made in one piece, mounted on the propeller hub. The blade foil passes into the blade flange via a fillet joint forming the weakest portion for the possible destruction of the blade in the cross section of its foil, located immediately adjacent to the fillet joint.

  • Publication number: 20210114699
    Abstract: The invention relates to a method for determining the direction and the amplitude of a force applied to a system (IO) comprising a stationary portion (13) and a mobile portion (12) which can deform when exposed to said force. Mechanical deformations applied to the mobile portion when exposed to said force are measured by measuring a distance between the stationary portion and the mobile portion in the direction of application of the force, and the distance measurements are processed in order to determine the amplitude and the direction of the force.

  • Patent number: 10710694
    Abstract: The drive unit is designed to be mounted on a marine vessel, including a mobile housing, and is able to pivot around an axis against the hull of the marine vessel. A drive shaft mounted rotary is against the mobile housing and is supported by two roller bearings. A propulsion element rotates in solidarity with the drive shaft. The propulsion unit has, at the front, at least two braking and locking systems of the drive shaft located in an area between the upstream rolling bearing and propulsion element.
