Abstract: A towable lawn sweeper comprising a housing, a hitch assembly, a sweeper assembly and a sweeper height adjustment assembly. The hitch assembly is rigidly coupled to the housing and includes a clevis comprising a plurality of connector members forming a plurality of connection positions to adjustably couple the lawn sweeper to a tow vehicle. The sweeper assembly is rotatably coupled to the housing and includes at least one brush that is attached to an axle of the sweeper assembly in a spiral pattern about a longitudinal axis of the axle. The sweeper height adjustment assembly is pivotably coupled to the housing and includes a height adjustment bar pivotally mounted to the housing, a lever extending from the height adjustment bar generally perpendicular, a height retention member pivotally connected to the hitch assembly, and a fastener to releasably secure the lever to the height retention member.

Abstract: The present invention relates to methods for the separation of materials from heterogeneous fluids and provides a means of effecting stimulant-sensitive flocculation and consolidation of solid suspensions within a liquid medium. Specifically, the present invention provides a method of controlling the state of a suspension of solid particles in a liquid, including applying to the suspension a stimulus adapted to control inter-particle forces between the solid particles. The stimulus is reversibly operable to control attraction and/or repulsion. Means of consolidating a sediment bed and of separating the resultant liquids-rich and solids-rich phases are also within the ambit of the invention.

Abstract: A lawn and garden cart has a frame and an axle attached to the frame. A pair of wheels are attached to the axle, each wheel being rotatably attached to an opposing end of the axle. A longitudinal tow bar is attached to the frame at a first end, the tow bar including a connector at a second distal end. The cart further includes a container having a base, a plurality of generally vertical sidewalls and an angled rear wall, the container being pivotally attached to the frame and releasably coupled to the tow bar.
