A shaft mounting assembly includes an elongate shaft with an outer surface having a substantially circular cross-section and a cylinder having an inner surface defining a bore housing the shaft. A spring having a substantially circular discontinuous band with correspondingly shaped axially arcuate inner and outer surfaces. One of the surfaces comprises a groove, and the spring is positioned in the groove with both axial edges of the band located therein. In a de-energised state of the spring, the height of the band is greater than the depth of the groove, a portion of the band between the axial edges protruding out of the groove, the axial width of the band being less than the width of the groove; and, an energised state with the spring compressed within the bore to reduce the height of the band and increase the axial width compared to the de-energised state.

A connector assembly for use in a medical device system is provided. The connector assembly includes a female connector including a jack and at least one female electrical contact disposed in the jack, where the at least one female electrical contact includes an outer ring and leaf springs extending both radially inward from the outer ring and longitudinally along the jack. The connector assembly also includes a male connector including a plug adapted to be inserted into the jack of the female connector, and at least one male electrical contact disposed on the plug, where the at least one male electrical contact is configured to electrically couple to a corresponding female electrical contact of the at least one female electrical contact by contacting the plurality of leaf springs of the corresponding female electrical contact when the plug of the male connector is inserted into the jack of the female connector.

A gas turbine engine component includes an inner support structure surrounding an engine center axis and fixed to an engine static structure, an outer support structure spaced radially outward of the inner support structure, and a curved beam comprised of a plurality of curved beam spring segments that are positioned adjacent to each other to form a ring. The inner and outer support structures are coupled together around the curved beam to enclose the curved beam therebetween and form an assembly. A bearing is spaced radially inward of the assembly.

A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

A device for mounting a load to a carrier is described. The device includes a first support configured for fixation to the carrier; a second support configured for fixation to the load. The first and second supports are spaced away from each other viewed along a main load bearing axis of the device. The device further includes an outer shell extending along the main load bearing axis, and an inner member that is within the outer shell. The device includes a damping material connecting the inner member to at least the outer shell, wherein one of the outer shell and the inner member connects the first support and the second support to each other.

An annular spring for a bearing assembly of gas turbine engine is provided. The annular spring includes a multiple of ligaments between an inner support and an outer support.

A nonlinear mechanical element including a buckling column and hard stops. In one embodiment when the nonlinear mechanical element is subjected to an increasing compressive load, the buckling column buckles at a critical load, resulting in reduced stiffness past the critical load. One or more lateral hard stops may be provided adjacent to the buckling column to prevent the buckling deformation from exceeding a certain extent, and axial hard stops may be provided to shift the load path away from the buckling column when a certain amount of compressive displacement has been reached.

A dispensing pump (10) for liquids, viscous materials, foams, gels, etc. includes a resilient cup spring (18) so that the entire pump can be more easily recycled. The dispensing pump (10) includes a base portion (12), an inlet valve (14), a piston valve (16), a cup spring (18), a spring guide structure (20) and a pump actuator (22). When actuated, the cup spring (18) is elastically deformed over opposing spring ribs (39), and then upon release, the cup (18) elastically returns to its normal at rest shape, returning the guide (20) and pump actuator (22) to their normal at rest positions. The cup spring (18) includes structures which interact with the piston valve (16) to open the outlet valve.

A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

A contact ring including a ring-shaped structure formed of an electrically conductive material. The ring-shaped structure has a plurality of projections on at least one side and a plurality of blades on at least one side. The projections and the blades penetrate an electrically insulating surface layer of each of a pair of contact elements and contact an electrically conductive material of each of the contact elements to electrically connect the contact elements.
