An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.

An attendant-assisting baby walker that allows an attendant to remain upright while comfortably helping a baby to practice walking is provided. The attendant-assisting baby walker includes an open-top body suit with attached right and left support straps. The body suit includes both a torso-encircling component and a crotch component. The crotch front and back attach at or near the lower front and lower back edges of the torso-encircling component, respectively. The torso-encircling component is configured with a zipper, allowing fast and easy placement and positioning of the baby. The support straps are preferably adjustable to accommodate attendants of varying heights. Optionally, the torso-encircling component is configured with a width-adjustment mechanism, such as one or more cinches to improve the fit.

A master link for a chain assembly is provided. The master link includes a body member with a first side, a second side positioned opposite the first side, a shoe surface configured to receive a track shoe, and a rail surface positioned opposite the shoe surface. The master link also includes first and second apertures extending through the body member from the first side to the second side and third and fourth apertures located between the first and second apertures. The master link also includes a strut member dividing the third and fourth apertures. The master link also includes a first gap located in the body member and extending from the first aperture to the third aperture and a second gap located in the body member and extending from the fourth aperture to the second aperture. The master link further includes a third gap located in the strut member and extending from the third aperture to the fourth aperture.

Engineers have found that use of a slot and tab method to assemble a fabrication assembly is limited to fabrication assemblies that will be subjected to relatively low stress. In order to expand the use of the slot and tab method to fabrication assemblies that are subjected to relatively higher stress, the present invention increases the fatigue resistance of a welded slot and tab joint. A fabrication assembly includes a first fabrication element including a perimetric inner surface defining a slot and a second fabrication element including a tab. The tab includes a shoulder that includes a perimetric side surface. The tab is cooperative with the slot to lock the first fabrication element to the second fabrication element. At least one of the perimetric inner surface and the perimetric side surface includes portions that are oriented to one another at an angle different than 0&#xb0; and 90&#xb0;. The geometry of at least one of the shoulder of the tab and the perimetric inner surface defining the slot can increase the fatigue resistance of the welded slot and tab joint.
