Abstract: A noise reducing wall system is provided. The noise reducing wall system includes first and second board layers facing in parallel with each other along a longitudinal direction thereof, a heat insulation member surrounded by the first and second board layers, and a stud connection structure that fastens the first and second board layers using a stud bolt passing through the heat insulation member to connect the first board layer and the second board layer. The stud bolt connects the first and second board layers in a thickness direction and has a bent portion extending in the longitudinal direction and disposed at an intermediate point in the thickness direction.

Abstract: An apparatus (10) for visually indicating a loose wheel nut (57) on a wheel of a motor vehicle has a plurality of wheel nut engaging members (12, 14, 16, 18, 20). Each wheel nut engaging member is rotatable with a respective wheel nut to which it is engaged and has a pointer (26) for indicating a start position of the wheel nut engaging member. Any two adjacent wheel nut engaging members of the plurality are interconnected by an elongate member (28) which is resiliently flexible so as to define an endless configuration of spaced apart but interconnected wheel nut engaging members. In use, any loosening rotation of a first wheel nut (57) will cause the engaging member (12) which engages that wheel nut and its pointer (26) to rotate therewith, thereby providing a visual indication of a loosening of that wheel nut.

Abstract: A utility box having a housing, and a ring that forms a hole that receives an attachment from a cover. A fastener retention piece has a first recess in a first surface, a second recess within the first recess, and a third recess in a second surface. The first and second recesses retain fasteners when the first surface is adjacent a lower surface of the ring. The third retaining recess retains a fastener when the second surface is adjacent the lower surface of the ring. The fasteners secure the attachment depending from the cover, and the recesses prohibit complete rotation of the fasteners.

Abstract: A system of locking a pinch bolt assembly through a yoke arm of a vehicle steering assembly. The yoke arm of a steering assembly has an outward end, a forward face and a rearward face. A bolt receiving aperture through the yoke arm connects the forward face and the rearward face. A pinch bolt is fitted through the bolt receiving aperture to control the radius of an aperture for receiving an adjustment bushing. The head of the pinch bolt impinges against a selected one of the rearward and forward faces and a nut fitted to the bolt is tightened against the unselected face resulting in the head and nut pressing against their respective faces. A C-shaped channel section is fitted around the forward face, the rearward face and the outward end of the yoke arm. The channel section includes coaxial apertures fitted around the head of the bolt and the nut, respectively, for preventing the rotation of the nut and the bolt and thus preventing the nut and bolt from loosening.

Abstract: A microwave tuning device including a cylindrical metal bush having an internal screw thread. A metal rod-like plunger is axially displaceable within the plastics bush. A plastics bush is fitted over one end of the plunger and fixed thereto by means of splines and grooves. The bush is inserted into the internal screw thread so as to form a corresponding mating screw thread on its outer periphery. A plurality of fingers extend from one end of the metal bush and resiliently engage the outer periphery of a plain portion of the plunger so as to provide resistance to unintentional rotation of the plunger in the metal bush and electrical interconnection therebetween.

Abstract: A bonnet is locked to the body of a valve into which the bonnet screws by a sheet metal bonnet lock which includes a portion that will mate with facets on the bonnet or with the sides of the valve body. Another portion of the bonnet lock is then deformed to mate with the other of the bonnet facets or valve body sides. The portion of the bonnet lock that mates with the facets on the bonnet circumscribes the bonnet such that one portion of the bonnet lock is fixed to the bonnet and the other portion is fixed to the valve body following deformation of the bonnet lock to prevent the bonnet from turning relative to the valve body.
