Abstract: The rolling bearing comprises a ring (30) made in two relatively axially movable ring parts (31,32) and another ring or shaft (40) between which rolling elements (20) travel, and an elastically yieldable device (50) cooperative with a housing and one of said ring parts and capable of being placed in a first state corresponding to an inactive prestress and a second state corresponding to an active prestress. This elastically yieldable device (50) comprises a support (51) in the form of a split washer (5100), a detent mechanism (521) with at least two projecting lugs (5212) and an elastomeric collar-shaped element (53).

Abstract: An articulated marine structure for an offshore body of water which is subject to wave movement. The structure includes at least two floating elements which are pivotally joined along a common edge to permit relative movement between the respective elements in response to wave action. An energy accumulator is operably connected to the respective floats, and is actuated by movement of either float whereby to initiate conversion of wave energy into an alternate, usable energy form.
