Abstract: This liquid applicator covers all sides of substantially flat and dimensional surfaces of boards or siding with stain or paint in a uniform manner. The applicator has an upper and lower series of rollers and wiping agents, a set of vertical rollers, and a paint collection assembly. Preferably, some of the upper rollers and some of the lower rollers will consist of horizontal wet-rollers which receive liquid from an outside source. The remaining rollers are horizontal dry-rollers which absorb, smooth and buff the surface. The vertical rollers coat the side aspects of a board. All rollers spread paint rapidly over all board surfaces in a uniform manner. The main components have adjustment features: the rollers move vertically and toggle clamps and the like permit custom selection and sizing for each of the rollers and wipers. A catch pan has a drain plug at or near its lowest point.

Abstract: A bone preparing tool for use with a percutaneous bone access system. The bone access system penetrates the interior of a bone. The bone preparation tool allows a surgeon to prepare the interior of a bone for therapeutic treatments. The tool includes a handle, flexible rod and, bone preparation tip, which may include an off-set wedge, a banana wedge, a tapered tip, and a pedestal tip. Each tip has specialized functionality in bone preparation. The flexible rod and specialized tip are inserted through a curved cannula and employed for bone preparation. This tool is useful when implementing a variety of bone therapeutic treatments which benefit from internal bone access and preparation. Current tools are limited and cannot properly be used on bone that is healed or hardened. This invention allows a transpedicular or extrapedicular approach to a bone and provides sufficient tensile strength but flexibility to affect optimum functionality.

Abstract: An aerator for mechanically inducing near laminar flow and controlled turbulence in a liquid waste treatment lagoon or pond. A blower, blower mount platform, diffuser modules, aeration manifold, aeration chamber, an adjustable, telescoping aeration chamber extension, baffles, and buoyancy apparatuses attach to a frame. The diffusers are located beneath the surface of the body of liquid at a predetermined, fixed depth. The blower supplies air to the diffusers and liquid-bubble mixture is released into an aeration chamber where artificial aeration is maximized. The mixture then rises through the aeration chamber. Bubble dissipation and flow conditioning baffles force bubbles to coalesce and vertically dissipate into the atmosphere. The liquid flows over the top of the baffles and a flow manipulation rim to radiate outward and parallel to the pond surface with minimum turbulence at an optimum flow discharge rate. The aerator provides optimized oxygen transfer at low energy costs.
