Abstract: A chassis having a main member carries adjustable side members defining an area for the reception of berm forming particulate material conveyed by an air flow from a remote source. The discharged material forms a continuous berm of constant size and shape. Wheel assemblies are adjustably carried enabling the berm cross-sectional shape to best suit the job requirements. Forward travel to the apparatus may be imparted by a steerable tongue assembly.

Abstract: A biodegradable product for use as a ground cover or in the formation of a berm and comprising a major component of organic particulate as compost or a mulch containing compost. Additional components include granular molasses, granular guar, cotton seed meal and soy bean meal. A blower system for delivery of the product is disclosed in U.S. Pat. No. 6,036,406 incorporated herein by reference, and which discloses a vehicle supported system for mixing and discharging the product. The present product applied as a blanket serves to inhibit erosion and promote plant growth. When used in berm construction, the product constitutes a barrier aiding in the confinement of hazardous matter.

Abstract: An apparatus and method for coloring aggregate wood material by directing a flow of material onto vertically spaced, perforate conveyors with each conveyor served by conduits discharging curtains of liquid dye. A drive system for the conveyors includes the provision of driving the conveyors at different speeds to increase aggregate depth for saturation purposes. Conduits of the spray system have oversized orifices directing discharges onto deflectors for curtain formation. Curtain impingement includes the aggregate material in transition in between conveyors. An inclined conveyor and pan returns dye removed from the material to a catch basin.
