Abstract: An adjustable mounting system for wall-mounted shelf units is provided. The mounting system of the shelf unit comprises at least one horizontal support, situated preferably in proximity to the wall surface near the upper section of the shelf unit. The horizontal support is attached to, and slides laterally in clamping brackets that have been mounted to a wall. One part of the brackets are designed to be fastened to wall vertical support columns or studs, and incorporate a second portion that provides a clamping mechanism that attaches to the horizontal. The horizontal support is preferably fastened at each end to the shelf unit. One or more vertical columns are located between the shelves of the shelf unit and are located proximal, and optionally anterior to the horizontal support. A clamping element, which is preferably a plate with holes drilled into it, is placed proximate to the vertical support columns.

Abstract: A soil spreading scraper device comprises a cutting blade for cutting a top layer of soil from the ground, a kicker for throwing the cut soil rearward from the cutting blade, and an impeller member rotatable within a plane of rotation extending upward and rearward from the cutting blade for capturing the soil thrown by the kicker and spreading the cut soil generally radially outward relative to an axis of rotation of the impeller. A gearbox which receives power from a power takeoff of a towing vehicle directly drives the rotation of the impeller member in the preferred embodiment. The blades of the impeller members may include recessed portions adjacent the impeller axis in some embodiments to encourage soil being received in the impeller member even at higher rates of rotation, for example in the range of 250 to 320 RPM.

Abstract: Modifications to the structural elements of racks/shelves for component shelves, and in particular, audio components are provided in order to improve the sound produced by the system by minimizing the effects of vibration on the equipment positioned on the shelves. In particular, adding a series of grooves to the lower surface of each shelf was found to be of assistance in attenuating the vibration measured on the shelf surface. Additionally, using vertical supports manufactured of a tube of a composite fibre material, such as a carbon fibre/graphite reinforced plastic (GRP) or a solid metallatic support, such as a support made of an aluminum rod, was also found to attenuate the vibrations measured on the shelf surface. As such, a method and device for ameliorating the effects of vibration on vibration sensitive equipment is provided.
