Patent number: 6126362Abstract: A protective bank damming device useful for damming and controlling the flow of a liquid, the liquid most commonly being water. The damming device barrier member is inflated with water to provide a form to the barrier member, and anchoring weight to keep the barrier secured to the substrate surface. The barrier member provides support for a skirt member extending from the top side of the barrier to a skirt distal edge abutting against the flood side substrate surface. A skirt sealing means is applied along the skirt distal edge, with the purpose of preventing leakage under the skirt and barrier member, and utilizing natural leakage inherent in this type of liquid-anchored dam, reducing the hydrostatic pressure under the skirt and barrier relative to the dammed water. This pressure differential keeps the damming device securely anchored to the surface.Type: GrantFiled: March 1, 1999Date of Patent: October 3, 2000Inventors: Timothy L. Carter, Daniel B. Carter
-
Patent number: 6102620Abstract: A rubber sheet is formed in a bag shape, and a seam portion of the bag-shaped rubber sheet is fixed to a summit portion of an overflow dam. When the bag-shaped rubber sheet is expanded, a rubber dam is raised, thereby damming up water and adjusting the amount of running water. Next, when the bag-shaped rubber sheet which has been expanded is contracted and collapsed, the rubber sheet is supported by pipes, which extend substantially horizontally from the summit portion of the overflow dam toward the downstream side at a predetermined distance from each other. For this reason, the rubber sheet hangs down with its own weight and with the weight of water running downstream so as to droop down between the pipes. As a result, a rubber dam that does not bulge at the downstream side is obtained.Type: GrantFiled: January 8, 1999Date of Patent: August 15, 2000Assignee: Bridgestone CorporationInventor: Tateo Muramatsu

The panel is given such formed side edges that adjacent panels can overlap or enmesh one another where they meet to close a gap therebetween. It is optional that the panel be stackable with other like panels, for greater convenience during non-use periods, as while being transported and/or during storage. Given the foregoing, the panel is meant to replace straw bales as ditch checks because the panel is very much lighter, is non-absorbent and inexpensive, and is indefinitely reusable.Type: GrantFiled: November 13, 1995Date of Patent: April 22, 1997Assignee: Panel Products, Inc.Inventors: Michael R. Baum, Leo R. Baum

Patent number: 5538360Abstract: A crest gate has movable panels controlled in position by inflatable bladders. Air pressure to the bladders or from the bladders is provided to a control system that automatically regulates panel position. Air is bubbled out of a line that is normally below the water level behind the dam and crest gate panels. An actuator assembly is coupled to a valve for selectively venting the bladders. An elastomeric tire is used to create a positioning effect on the valve such that the control system maintains a precise water level. The gate configuration is improved to resist higher loads.Type: GrantFiled: March 2, 1992Date of Patent: July 23, 1996Inventor: Henry K. Obermeyer

Patent number: 5470177Abstract: A barrier wall for containment of flood waters composed of multiples of modules which are easily transported to the site and erected without tools, by only a few persons with no special skills or training. Flexible coversheets, having foam seals which conform the modules to the ground and prevent flood waters from undercutting the ground and rendering the wall unstable are placed on the ground. Compartmented flexible ballast cell units are placed on the cover sheets just over the seals. The edges of the coversheets are coupled together as are the ends of the ballast cell units for continuity of the wail. The ballast cells can then be filled with water, sand, earth, gravel or other available material and the front portions of the cover sheets brought up and over the ballast cells to form a wall. An additional tier can be added to double the height of the wall.Type: GrantFiled: March 2, 1994Date of Patent: November 28, 1995Inventor: Christopher T. Hughes

Patent number: 5439316Abstract: A reusable flood barrier is provided to erect reusable flood barrier banks. The flood barrier comprises (a) a front panel having a front face, a rear face, a top edge, a pair of side edges, and a base; (b) a rear support attached to the rear face of the front panel to prop the front panel on the base; and (c) an elongated clamp removably and adjustably affixed to the front face of the front panel. The clamp has an edge disposed proximate and substantially parallel to each side edge of the front panel respectively. The clamp is capable of anchoring a long edge of an elongated interconnection gasket. The gasket is capable of placement over the gap between a side edge of the front panel of a first flood barrier and an abutting side edge of the front panel of an adjacent flood barrier. The anchoring action of the clamp on adjacent flood barrier front panels enables the gasket to provide a water seal between the front panels.Type: GrantFiled: July 28, 1994Date of Patent: August 8, 1995Inventor: Cecil A. Richardson

Patent number: 5330290Abstract: A levee gate and the process for the production thereof. The levee gate of the invention includes a rectangular sheet of thermoplastic material with a rectangular sleeve located on one edge of the thermoplastic material, the rectangular sleeve being a portion of the rectangular sheet fused to the rectangular sheet. The process for the production of the levee gate includes extruding a cylindrical tube of thermoplastic material, inflating the cylindrical tube as it is extruded to provide an inflated length of tube, flattening the inflated length of tube without fusing the opposed walls of the tube to each other, and continuously fusing a portion of the opposed walls together to form a seam.Type: GrantFiled: February 19, 1993Date of Patent: July 19, 1994Inventor: John F. Hogan

Patent number: 5244309Abstract: A self supporting rubbery flow blocking device of substantial thickness is mounted in a fluid passageway to automatically regulate flow. Due to its variable elastic stiffness, increases in pressure will cause the device to begin to flex away from the pressure, beginning at its free end. Further increases in pressure will cause the location of the flex to move towards the secured edge of the invention, unblocking larger areas of flow. Decreases in pressure will allow the invention to increase its blocked area until it regains its fully blocking state.Type: GrantFiled: March 5, 1992Date of Patent: September 14, 1993Inventor: Neil C. Murdock

Patent number: 5236281Abstract: A device for damming and diverting liquid on a spill surface has an elongated, pliable dike having a first end, a second end and an exposed surface. The exposed surface is inherently tacky so that it is adherable to the spill surface to prevent flow of liquid past the dike. The dike is preferably triangular and made from a substance, such as polyurethane, so that all exposed surfaces on the dike are inherently tacky, including those created when a portion of the dike is severed to tailor the dike for specific damming needs. The device also includes a joint housing which may be engaged on abutting ends of adjacent dikes to seal the joint. A method for creating a liquid control zone on a spill surface utilizing the dike of the present invention is also disclosed.Type: GrantFiled: July 15, 1992Date of Patent: August 17, 1993Assignee: New Pig CorporationInventor: Dennis G.
