Patent number: 8596930Abstract: An erosion control barrier for installation in a drainage path in a service environment. The erosion control barrier includes a unitary permeable sheet which is bent along a longitudinal axis to provide an upslope side, a downslope side and a longitudinally extending apex. The permeable sheet is constructed of a degradable material so that the erosion control barrier has a design service life in the service environment and a design material life in the service environment. The design material life is longer than the design service life. The permeable sheet is designed to be sufficiently transversely stiff and resilient during the design service life to enable the erosion control barrier to be self-supporting. The permeable sheet is designed to substantially disintegrate within the design material life.Type: GrantFiled: May 10, 2007Date of Patent: December 3, 2013Assignee: Nilex Inc.Inventors: Walter van Woudenberg, Ian Wilson

Patent number: 6737472Abstract: A reinforced networked polymer/clay alloy composite is produced by contacting a monomer/clay mixture with a reinforcing agent. The monomer/clay mixture comprises a monomer, a cross-linking agent and clay particles. An initiator means is used to initiate polymerization of the monomer/clay mixture, while the cross-linking agent concurrently acts to network oligomeric and polymeric species formed during polymerization to produce a networked polymer/clay alloy in the presence of the reinforcing agent. The networked polymer/clay alloy is intimately integrated with the reinforcing agent such that, on exposure to water, the networked polymer/clay alloy swells with substantially no clay separating from the composite.Type: GrantFiled: April 15, 2003Date of Patent: May 18, 2004Assignees: Alberta Research Council Inc., Nilex, Inc.Inventors: Zhihong Zhou, John Donald Payzant, Walter Van Woudenberg
