Patent number: 7503885Abstract: A soft shell, flexible storage tank is provided, including corners of an improved configuration adapted to resist leaks. The walls of the tank and the corners are relatively more rounded and larger in radius than those of conventional flexible tanks. The walls and the improved corners act together to resist leaks. The rounded corners tend to reduce the effective pressure in the tank walls by loading the seams predominantly in shearing stress when the tank is filled with a liquid. The rounded corners are developed as panels, which are thermally bonded to produce secure and reliable liquid-tight seams. Each of the panels is bonded by lapped seams to others of the panels. Each of the rounded corners includes a generally triangular corner that is bonded to at least three other panels. In effect, the flexible storage tank functions as a pressure vessel, which tends to resist leakage.Type: GrantFiled: May 7, 2007Date of Patent: March 17, 2009Assignee: MPC Containment Systems LLCInventors: Edward Reicin, Jack Moreland

Patent number: 5150510Abstract: A mechanically strong, airtight, watertight seam provides for joining two panels of industrial strength fabric or material. The inventive seam has two connection systems. One system is a mechanically strong structural connection which is used to make the seam as strong as the fabric panel material. A second system is an all plastic slide closure in the form of a zipper connection which overlies the structural connection, joins the panels into a single cover, and makes the seam airtight, watertight and maintenance free.Type: GrantFiled: December 27, 1990Date of Patent: September 29, 1992Assignee: MPC Containment Systems, Ltd.Inventor: Jack Moreland

Patent number: 4818151Abstract: A fuel delivery system for a filling station provides a membrane which is formed as a continuous basin associated with at least one bulk storage tank and at least one remote delivery pump for dispensing the fuel upon demand with a plurality of pipes interconnecting the tank and the pump. The membrane at least partially surrounds the tank, completely surrounds the pipes, and extends under the pump for collecting any fuel spills or leakage. The earth or ballast supporting the membrane is graded to drain all collected fluids into a collection area, from which it may be pumped away. The membrane is under single walled fuel tanks and over double walled tanks. A frame supports the membrane above the tank while ballast is being packed around it.Type: GrantFiled: April 9, 1987Date of Patent: April 4, 1989Assignee: MPC Containment SystemsInventor: Jack Moreland

Patent number: 4778310Abstract: The invention process for installing an overliner membrane begins with preparing a site by digging a pit for the installation of fuel tanks, for example, which may be associated with leakage or spillage of fluids. Then, ballast is packed under and around the tanks to support and stabilize their position, the ballast rising to a level which is above the tanks but below points where the leakage or spillage may occur. Next, a frame is built over the ballast in the area where the leakage or spillage may occur. A membrane is spread across the surface of the ballast and attached to the frame in order to form a basin in which this leakage or spillage may collect. The frame and the membrane are completely covered with ballast in a manner which maintains the side walls of the membrane in a vertical position. A trench system for delivery pipes carrying fuel from the tank to outlying locations contains a trench liner membrane which surrounds the pipes and drains into the membrane basin.Type: GrantFiled: November 14, 1986Date of Patent: October 18, 1988Assignee: MPC Containment Systems, Ltd.Inventor: Jack Moreland

Patent number: 4682911Abstract: A secondary containment system which may be manufactured in a factory, shipped and installed in a reasonably low cost and fully usable manner. In one embodiment, a large membrane of material, completely lines a collection and containment pit along with radiating trenches which drain into the collection pit. There is substantial amount of membrane bulk which enables it to bunch in the corners and to provide slack which conforms to irregularities on the earthen walls and floor of the pit. Thus, localized stresses do not occur at places where the membrane bridges protections formed on the walls, in the corners, or the like. In another embodiment, the membrane covers a tank in the pit and drapes down to form deep areas where liquids may collect. A perimeter steel cable surrounds the hole. The membrane is attached to this cable so that the membrane is mechanically strong enough to meet the shoring requirements of the various occupational safety laws.Type: GrantFiled: March 8, 1985Date of Patent: July 28, 1987Assignee: MPC Containment Systems, Ltd.Inventor: Jack Moreland
