Abstract: Sediment-control fences designed to withstand hydrostatic forces associated with elevated backwater against the fence are disclosed. The fences are made of anisotropic fabric having different mechanical properties such as strength and stiffness in the machine direction versus the transverse direction. The anisotropic fabric may include fibrillated yarns in one direction and monofilaments in another direction. The sediment-control fences may be used without the necessity of wire or chain-link backed supports that are conventionally used to resist structural failure due to hydraulic overtopping of the fences.

Abstract: Sediment-control fences that are structurally enhanced to prevent failure due to hydrostatic and hydrodynamic forces are disclosed. The sediment-control fences comprise a permeable geotextile material and reinforcing straps located at controlled heights. The reinforcing straps provide added strength and stiffness at key structural locations along the height of the sediment-control fence.

Abstract: A transportable multi-chamber water filtration system useable at construction sites with sources of contaminated water is disclosed. The transportable multi-chamber water filtration system removes sediment and contaminants from contaminated water by combined processes of gravitational settling, filtration and coagulation of sediment by the use of flocculants. The system provides efficient removal of sediment and contaminants from the water around various sized sites.

Abstract: An interface unit for interfacing a peripheral bus of a computer system with a dispensing system for dispensing a material, such as gasoline, and which includes a plurality of dispensers for controlling the dispensing of the material. The interface unit includes a controller and a first communication link for providing bidirectional communication between the controller and the material dispensers. A second communication link is connected with an internal bus on the interface unit and the peripheral bus of the computer system to provide bidirectional communication between the controller and the computer system. The second communication link includes a window memory for storing code and a bus interface.
