A drive device for a movable furniture part includes a lockable push-out device for pushing the movable furniture part out of a closed position into an open position. The push-out device can be unlocked by virtue of the movable furniture part being pushed into an excess-pressure position located behind the closed position, as seen in the closing direction. An excess-pressure region is located between the closed position and an excess-pressure position. The drive device also has a damping device for damping the closing movement of the movable furniture part. The damping device has displacement-dependent damping, in which the damping force in a main damping region, located in front of the closed position—as seen in the opening direction, is higher than in the excess-pressure region.

A process of making a family cell of homogenous inner bladders with varying elasticity includes a forming a plurality of inner bladders from a first material with a first elasticity. The inner bladders have interior surfaces during inner chambers and exterior surfaces exposed to an outside environment. The inner chambers are configured to store a fluid. A family cell is formed by fluidly connecting the inner bladders. One or more hybrid bladders are selected from the inner bladders and a second material having a second elasticity is applied to the hybrid bladders. The second elasticity is less than the first elasticity, such that the second material reduces the elastic qualities of the hybrid bladder.

A front fork leg includes an inner chamber that absorbs by a gas spring a shock caused on a vehicle; an auxiliary gas spring chamber communicating with the inner chamber; an auxiliary piston provided in the auxiliary gas spring chamber; and a gas spring chamber side gas chamber sectioned by the auxiliary piston and communicating with the inner chamber, and the auxiliary piston moves to increase a volume of the gas spring chamber side gas chamber, as pressure inside the inner chamber increases.

The invention relates to the novel usage of shear-thickening and rheopectic non-Newtonian fluids as shock absorbers intended absorbing acceleration or impact via submergence of an object to be protected entirely into non-Newtonian fluid. Additionally, this invention relates to the novel usage of shear-thickening and rheopectic non-Newtonian fluids as shock absorbers capable of absorbing the force of impact or acceleration and effectively dissipating the force away from the object to be protected over an extended duration (greater than an instantaneous impact) more effectively than traditional shock absorbers.

An assembly includes a bearing having an annular shape, a bearing support radially outward from the bearing, a squeeze film damper having a first end adjacent the bearing and a second end adjacent the bearing support with the second end forming a squeeze film damping surface, and a first spring between the bearing and the bearing support with the first spring configured to resist a movement of the bearing to center a shaft radially inward from the bearing.

A damper system may include an inner damper having a first annular geometry and a textured surface. An outer damper may also have an annular geometry and be disposed about the inner damper. The outer damper may have a textured surface. The textured surfaces of the inner damper and outer damper may define a cavity that is configured to contain a viscous fluid.

A damping mechanism configured for use with a coupling of a power transmission assembly is provided including a cylindrical body having a first end and a second opposite end. The first end is configured for attachment to a first component of a power transmission assembly. A groove is formed in an exterior surface of the cylindrical body adjacent the second end. A cylindrical ring generally complementary to the groove is positioned partially within the groove such that a void exists between an inner surface of the cylindrical ring and the cylindrical body within the groove. A viscous material is arranged within the void such that non-concentric movement of the cylindrical ring relative to the cylindrical body causes displacement of the viscous material.

A gas spring device includes a gas spring which generates a force proportional to a differential pressure between an inner space pressure and an atmospheric pressure, a suction/discharge part which can adjust a gas amount in the gas spring inner space, a rotary body which is connected to the gas spring, to which a torque due to the force generated by the spring is applied, a displacement part which is connected to the rotary body, and is displaced in conjunction with a rotary body rotary movement, a speed change part which is arranged in one of or both of between the rotary body and the displacement part and between the gas spring and the rotary body, and a torque compensating part which sets the torque applied to the rotary body to substantially 0 when the inner space gas amount of the gas spring is at a predetermined value.

An apparatus and associated method is disclosed for a riser hanging system. The apparatus includes a first elongated member with a provision for a first external mechanical coupling at a distal location on the first elongated member. A second elongated member is mechanically coupled to the first elongated member at proximal locations on the first elongated member and the second elongated member. A third member is mechanically coupled to a first portion of the first elongated member. The third member includes a fourth member to move through at least a second portion of a length of the second elongated member. Mechanical couplers associated with the second elongated member are provided for a second external mechanical coupling of the riser to the apparatus. The riser may be hoisted using the apparatus for better control during coupling to the wellhead.
