20120243819 | BEARING WITH THREE ROWS AND MORE MOBILE BODIES - A wind turbine rotor hub bearing where the series of mobile members include more than two annular series of such members whereof at least two have different median diameters which are arranged in more than two rows scaled along the bearing rotational axis, with two end rows each comprising a series of roller bearings having individually a rotational axis transversal to the axis and at least an intermediary row of mobile members comprising balls. | 09-27-2012 |
20130323061 | SEALING DEVICE - The present invention relates to a sealing device including a sealing circular piece, an inner ring and an outer ring, with one being able to rotate relative to an axis. The circular piece is arranged between the two rings and comprises two circular lips arranged in a groove inclined with respect to the axis of rotation. The groove is provided on the outer face of the inner ring. An attachment profile is fixed in an orifice formed in the outer ring. The inclination of the groove makes it possible to increase the potential contact surface area perpendicular to the axis of rotation of the crown ring, since, for a given distance between an outer edge and an inner edge of a ring, the groove can be longer, improving the resistance of the top lip to expulsion. The two lips are prestressed in the groove allowing for a better hold. | 12-05-2013 |

20150354927 | ARMOURED VEHICLE BODY SHELL WITH SMALLER STRUTS - A body shell of an armoured vehicle includes a front face carrying an armoured windscreen projecting towards the outside of the body shell, at least one side wall including an opening, said side wall being integral with the front face at a strut which is defined by a part of the side wall included between an edge of the opening and a rim of the side wall situated furthest outwards at the front of the vehicle. In the armoured vehicle body shell, the strut extends beyond the front face towards the outside of the body shell, and at least one edge of the opening is situated near the front face, so that the junction between the strut and the front face of the vehicle is at the vicinity of the edge of the opening which forms a rear edge of the strut. | 12-10-2015 |

20140332238 | Braking Systems And Methods For A Winch Drum - Braking systems and methods are provided for a drum wench system having a winch drum having an outer surface and a winch drum braking system. The winch drum braking system has a first brake having a first brake lining, located adjacent to the winch drum, and a first three-ring ratchet linkage system connected to the first brake lining. The first three-ring ratchet linkage system is rotatable and adapted to move the first brake lining to a first position or a second position with respect to the outer surface of the winch drum. In the first position, the first brake lining contacts the outer surface of the winch drum to apply break force thereon, and, in the second position, the first brake lining is separated from the winch drum. | 11-13-2014 |
