Abstract: A suspension tuning ring formed as a hollow a cylinder having an outer surface and an inner surface defining a wall, a top, a bottom, and a slit through the wall. The outer surface has an outer diameter that is larger than the outer diameter of a coil spring and the inner surface has an inner diameter that is less than the diameter of a coil spring. The top and bottom of the ring each include a top and bottom retaining groove that are spaced apart, shaped and dimensioned to accommodate each coil. At least one of the top and bottom retaining grooves are dimensioned, or include separate retaining structures, to retain the coils within the retaining grooves. The ring assembled by parting it along the slit and fitted between adjacent coils of a coil spring of a suspension system such that the coils are retained within the top and bottom retaining grooves.

Abstract: The present invention is a sharpening tool and sharpening system for sharpening snowmobile carbide wear rails and studs and a kit of parts that includes the sharpening tool and a steering member having a carbide wear rail. The sharpening tool is attachable to the chuck of a hand held drill and includes a shaft attachable to the chuck of the hand held drill and cylindrical head affixed to the shaft. The cylindrical head includes a rail groove surfaced in an abrasive material for sharpening wear rails.

Abstract: A submersible buoy comprising a body defining a space; a gas compressor in fluid communication with a pressure vessel, where the gas compressor is capable of releasing gas from the pressure vessel into the space and of sucking gas out of the space into the pressure vessel; a battery that powers the gas compressor; and a controller in electronic communication with the gas compressor, where the controller controls the operations of the gas compressor.

Abstract: A card cage formed of mating, identical halves provides parallel slots for circuit boards carrying snap-on retainer clips with integral pawl-like clasps which lock over ridges on the exterior of the card cage. The clip is released from the cage by squeezing the clasps with one hand before withdrawing the circuit board. Slotted side brackets capture mating ribs on the card cage halves to assemble and mount the card cge to a wiring clost panel.

Abstract: A modular faceplate system having four levels of modularity includes a standard faceplate, a plurality of secondary support members, and a plurality of modules. The faceplate may be secured to a variety of support structures such as an outlet box, a modular box and a wall box. The faceplate has an elongated opening formed therein for the secondary support members. The secondary support members support the various different modules in various configurations. The modules can support a variety of electrical devices including plugs and electrical connectors. The faceplate, secondary support members and modules all include snap-type fastening means such that a desired faceplate configuration can be assembled from the component parts without the use of hardware.
