An apparatus includes an upper member, a lower member disposed beneath the upper member, and a spring disposed between the upper member and the lower member. The upper member has a pin extending downward therefrom. The lower member has a seat configured to receive a free end of the pin. The spring surrounds the pin, and has a free length that is less than the length of the pin. In an unloaded state, the free end of the pin contacts the seat and the spring applies a compressive force to prevent relative lateral movement between the upper member and the lower member. When the lower member carries a load in a loaded state, the load applies a tensile force to the spring that forms a gap between the free end of the pin and the seat, which allows relative lateral movement between the upper member and the lower member.

A device for reducing impact forces upon a surface includes a base comprising a first contact portion and a transition portion, a contact member disposed between the base and the surface; and a biasing portion disposed between the first contact portion of the base and the surface. At least a first portion of an impact force upon the surface is transferred from the contact member to the base, and a second portion of the impact force is subsequently returned to the surface, the second portion being less than the first portion.

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

A locking isolator includes one or more joints. The one or more joints are configured to transition between a clearance fit state and an interference fit state in response to a change in temperature. The locking isolator includes a dampener. The dampener is configured to attenuate transmission of vibration through the one or more joints when the one or more joints are in the clearance fit state.

The present invention relates to damping devices of an electric motor of an airflow generating apparatus and the apparatus having these devices, the devices having a first part, a second part, and a damping element, the damping element being arranged such that it determines an attachment between the first part and the second part, and having at least one central wall having two longitudinal ends. At least one of the two longitudinal ends of the at least one central wall is defined to form an angle with respect to the first part such that an imaginary transverse surface containing the at least one of the two longitudinal ends can be defined parallel to an imaginary joining line (A) between a center of masses of the at least one central wall and a center of gravity of the electric motor.

A vibration isolation system includes at least one first region and at least one second region that are positioned mutually, at least one first hinge member engaged with said first region, at least one second hinge member engaged with said second region and at least one lever connected with said first hinge member and said second hinge member to be at least partially movable in the direction of at least one first axis. Accordingly, at least one lever guiding element is used to minimize vibration transmission between the first region and the second region and said lever guiding element is configured to bring an instantaneous center of rotation depending on the input vibration frequency of the first region to be aligned with the second hinge element attached to the second region which is required to be protected from vibration.

A device includes a cylinder sleeve (3, 13), which is at least indirectly arranged at a housing (7) and at least three radially outward extending journals (5). Each journal (5) comes to rest, at least on one side, against a roller element (6a, 6b) accommodated at the housing (7) in order to support the cylinder sleeve (3, 13) on the housing (7) in at least one tangential direction. The device can be designed, in particular, as a planetary transmission or as an electric machine.

A base isolation supporting device 1 includes a support 8 which is adapted to be affixed to an outer casing 4 of a fixture 3 to be supported on a floor 2, so as to receive the load, acting in a vertical direction V, of the fixture 3, and which has a cross-sectionally circular arc-shaped convex outer surface 7; and a rotating body 13 which, at a cross-sectionally circular arc-shaped outer surface 9 thereof, is adapted to be brought into contact with the cross-sectionally circular arc-shaped convex outer surface 7 of the support 8 slidably and rotatably in an R direction about a center O1, while, at a cross-sectionally circular arc-shaped convex outer surface 11 thereof, coming into contact with a flat surface 10 of the floor 2 rollably about the center O1, so as to receive together with the support 8 the load, acting in the vertical direction V, of the fixture 3 via the support 8.

A vibration isolation device for optimally decoupling shear forces that are orthogonal to the principal direction of isolation from microvibrations. A pivoting load support element is free to pivot about a pivot point in response to shear forces, with optimal isolation from coupling to the principal direction of vibration isolation. A friction free bearing for small motion is provided to respond to the forces perpendicular to the principal direction of vibration isolation. An internal load support plate associated with the pivoting element is supported by equalizing springs and is damped by an active actuator driven according to a sensor on the internal load support plate. Adjustment points, such as screws, adjust the pivoting element with respect to the fixed pivot point.

Disclosed is a passive shock-absorbing system for a sighting apparatus installed on a device including equipment generating the shocks, the system including two rigid plates substantially parallel to one another, via a first plate secured to the part of the device including the equipment and a second plate secured to the sighting apparatus, the plates being connected to one another by a position return component returning the plates to a determined relative rest position after absorbing a shock. The system is characterized in that the position return component includes a line-point-plane positioning unit with balls between the two plates and a set of elastic return members connecting the two plates to one another. A corresponding device is also desclosed.
