Abstract: A vehicle has a container that receives swept debris. A primary sweeper assembly has a primary axle with wound cables in a helical configuration. A primary shroud supports the primary sweeper assembly and the axle adjacent to its ends. Disk-shaped turbines are mounted on the axle within the shroud. A turbine is located adjacent to each end of the axle with a primary tube there above. A supplemental shroud encompasses the primary shroud. A supplemental turbine is coupled to and rotatable with the primary axle with a secondary tube.

Abstract: A manifold assembly is formed of a pipe. The pipe has an open interior. A fluid handling assembly has a plurality of downwardly facing spaced apertures in the manifold. A flexible tube extends downwardly from each aperture. The fluid handling assembly also has a supply of fluid. The fluid is adapted to kill and manage dinoflagelents. A line couples the supply with the tubes for the dispensing of the fluid. At least one water craft with a line couples the central water craft to the manifold. A sensor is provided to determine ambient conditions. The sensor is adapted to analyze the sensed ambient conditions and dispense the fluid at an appropriate rate.

Abstract: A new curb and gutter machine used in combination with a vehicle and characterized by its construction to include an adjustable cutter for trimming along the side of a roadway or curb, a sweeper for removing not only trimmed material but also other debris which might be along the side of the roadway, and a vacuum head for transferring the debris into a receptacle that is preferably mounted at the rear of the vehicle. The machine of this invention is further characterized by its utilization of braided cable to accomplish both the cutting operation and the sweeping operation, thereby significantly increasing the useful life of both the cutter and the sweeper.
