Abstract: A misting spray nozzle includes a hollow body having an interior wall descending from an upper end to a lower end. The interior wall tapers toward the lower end to form a choke. A channel section provides two fluid paths descending from an upper central aperture. A turbine is sized and shaped to fit closely within the choke and has spiral grooves on its outer surface. The turbine attaches to the body at its upper end and has a cone-shaped opening at its lower end. A conical core is sized and shaped to fit closely within the cone-shaped opening and has grooves spiraling in an opposite direction on its outer surface. The core is attached at its upper end to the turbine. The two sets of spiral grooves define a pair of intersecting fluid control paths that meet at the lower end of the body to create a dense mist.

Abstract: A personal transportation device includes front and rear sections having wheels mounted adjacent either end. The front section is hingedly attached to the rear section. A foot platform with binding is pivotally mounted to the front section. An overrunning clutch is attached to at least one wheel. A braking element is attached to the foot platform which is urged toward the upper surface of the front section by an elastic member. The braking element projects through a slot in the rear section and contacts a ground surface when the foot platform is tipped upwardly. When a leg of the user is drawn upwardly, the front section will move toward the rear section pivoting at the hinge portions. At least one of the front wheel and the rear wheel will roll toward the other. When the leg is pushed downwardly the overrunning clutch will lock and the device will move forwardly.
