An assembly for use in a bearing compartment having an axis includes a bearing outer race configured to be located in the bearing compartment. The assembly further includes at least one annular spring positioned in the bearing outer race and being asymmetric in at least one of the axial direction or the circumferential direction relative to the axis to reduce the likelihood of amplification of vibration experienced by the at least one annular spring.

A plastic spring, a pump core, a lotion pump and a press-type packaging container. The plastic spring includes at least one spring unit. Each spring unit includes a first support member, a second support member, and at least two torsion arms. The at least two torsion arms are arranged between the first support member and the second support member, and both ends of each of the torsion arms are respectively connected with the first support member and the second support member. Each of the torsion arms includes at least one vertical section, and an end of each vertical section is connected with the first support member or the second support member.

A riding outdoor power equipment vehicle, such as for grounds maintenance, having a chassis including a support area, an operator platform for supporting a rider and supported by the chassis, and a suspension assembly. The suspension assembly is configured to resist movement of the operator platform towards the support area of the chassis and includes a biasing element having a plurality of annular portions. At least two annular portions of the plurality of annular portions are spaced apart from one another when the biasing element is in a default orientation and are moved into engagement with one another upon compression of the biasing element between the operator platform and the support area. Compression of the biasing element provides an initial deflection response that decreases substantially in response to increasing loading being applied to the operator platform.

An electrical connector comprising a plug arranged and designed to connect to a receptacle. The plug includes an electrically-insulating body, a conductor ring, and a conductive member connected to the plug conductor ring. The receptacle includes an electrically-insulating body, a conductor ring having an axial inner bore and an annular groove facing radially inward, a conductive member connected to the receptacle conductor ring, and an electrically-conductive contact having a generally annular profile, at least a portion of the electrically-conductive contact received in and contacting the annular groove and at least a portion of the electrically-conductive contact not received in the annular groove. Upon insertion of the plug into the receptacle and substantially radially aligning the plug and receptacle conductor rings, the electrically-conductive contact is elastically deformed and provides electrical contact between the plug conductor ring and the receptacle conductor ring.

A 3D printed additively manufactured (AM) elliptical bifurcating torsion flexure assembly system includes a base section; elliptical bifurcating torsion springs, each including a bifurcated legs section supported by the base; a bifurcated elliptical torsion spring section contiguous with the bifurcated legs section; and a single upper section contiguous with the elliptical torsion spring section. The single upper section includes a connection component, and the device material includes Hot Isostatic Pressing (HIP) heat-treated Ti6Al4V. The elliptical bifurcating torsion flexure assembly is printed as one part by a 3D additive manufacturing process, and the bifurcation maintains consistent balance while being torqued. The stiffness-spring rate of the device is at least partly controlled by varying cross-sectional shape and diameters by the 3D additive manufacturing printing.

A dispensing pump includes a polymer compression spring assembly, base vents and a flow baffle. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The polymer compression spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. The venting ports allow air to escape when capping the container after filling and the flow baffle reduces or prevents the product from being pulled into the pump accumulator before residual air (headspace) has been evacuated from the container during the initial priming strokes.

A vibration isolation system includes multiple isolators between an inner object and an outer housing that surrounds the object. In one example the inner object may be a rack or container that holds electronics, such as printed circuit boards, and the outer housing may be a housing for a missile, such as a supersonic or hypersonic missile. The isolators have flexures to attenuate vibrations, isolating the inner object at least in part from vibrations encountered by the outer housing. The flexures may be oriented in different directions for different isolators to change the resonant frequency of the system for a given axis. In addition the isolators are able to compensate for differences in expansion between the inner object and the outer housing. The isolators may also include multi-part isolators that have spring-loaded wedge elements used to expand the isolators in one or more radial directions.

A method for making a device for coiling an elongated flexible object into a predefined shape includes the steps of winding a length of wire around an elongated first mandrel having a diameter approximately the same as a diameter of the object, winding the first mandrel, with the wire wound thereon, around a second mandrel which is configured to conform to the predefined shape, and heating the first and second mandrels to set the windings.

A component is described, in particular an inertial sensor for detecting acceleration forces, including a substrate, a mass structure, and a spring unit, the mass structure being pivotable along an axis in relation to the substrate with the aid of the spring unit, the spring unit including a first spring web and a second spring web, which are spaced apart from one another along a z direction. Furthermore, a method for manufacturing a spring unit is described.
