Re: claim 6, the reference discloses the outer bushing base (cylinder 36) is fixed to the first mount (col. 6, lines 10-25; fixed by compression fit including the radial direction) through a radial interference fit. Re: claim 8, the reference discloses the fastener (bolt shown in figure 1) includes a head (at body 16); and a shank (at vertical centerline through figure 1) projecting axially out from the head and sequentially through the second mount (16) aperture and the inner bushing bore (bore of cylindrical portion 26). Re: claim 9, the reference discloses the shank (shank of un-numbered bolt within 26) is radially next to (at distal end 32 of the inner bushing 26) the second mount (16). Re: claim 10, the reference discloses the shank includes a threaded section (at nut below) and a shoulder section (below bolt head below) projecting axially through the second mount aperture (aperture at 16 and the inner bushing bore from the head to the threaded section (section at nut below) and the mounting assembly further includes a nut (nut shown below) threaded onto the threaded section (section at nut identified below) with the inner bushing (26) clamped axially between the nut and the first mount. PNG media_image1.png 625 618 media_image1.png Greyscale Re: claim 11, the reference discloses the mounting assembly (10) further includes a washer (flat areas below bolts and nuts above) clamped axially between the nut and the inner bushing. Re: claim 13, the reference discloses the washer and official notice is taken that washers are well known to have a uniform axial thickness extending radially from an inner side of the washer to an outer side of the washer. See cited reference U.S. Dickson et al., U.S. 7,261,365, fig 3, washer 46; col. 4, lines 13-18. Re: claim 14, the reference discloses a housing structure (a fuel tank functionally for an air borne vehicle) for an aircraft engine of a first or second mount. Regarding claim 15, Kawachi et al. discloses an aircraft or vehicle assembly for providing controlled intercomponent movement to reduce internal stress and/or wear as noted above having; a first mount (14a-b, 18), a second mount (16) having apertures (apertures for the shank of the bolt), an outer bushing (member 12) having an outer bushing bore (bore of extension 36) into the first mount aperture (aperture of 14a-b and 18), an inner bushing (cylinder portion 26) including an inner bushing bore (bore for the shank of the bolt), an inner bushing base (cylinders 32, 34) and an inner bushing rim (flange 28) that projects radially out from the inner bushing base the inner bushing base projecting axially along the axis through the outer bushing bore (bore of member 12 and cylinder 36), the inner bushing rim (flange 28) axially next to the first mount (fig 1 fore and aft of gap 52) with the first mount (14a-b, 18) axially between the inner bushing rim (28) and the second mount (16), a fastener or bolt including a head (head of the bolt) and a shank (noted above) projecting axially along the axis out from the head and sequentially through the second mount aperture and the inner bushing bore to a distal end of the fastener; a washer (noted above) mounted on the shank; and a nut (see above depiction) threaded onto the shank to clamp the washer, the inner bushing and the second mount in a stack between the nut and the head. Re: claim 16, the reference discloses the inner bushing (cylinder 26) extends axially along the axis from an inner bushing first end to an inner bushing second end; the inner bushing rim (flange 28) is located at the inner bushing first end; and an axial distance from the inner bushing rim (28) to the inner bushing second end is larger than an axial thickness (the axial length of member 12) of the outer bushing (member 12 is axially shorter than cylinder 26).
