Patent number: 7249607Abstract: Systems, methods, and apparatus for servicing landfill conduits are disclosed. These systems, methods, and apparatus employ structures which facilitate access to and the servicing of buried landfill conduits, for example, one or more buried landfill laterals. In one aspect, the systems include an enclosure, at least one inlet conduit passing into the enclosure, at least one outlet conduit passing out of the enclosure, and at least one service conduit having a valve and an access port positioned between the inlet conduit and the outlet conduit. In another aspect, methods and portable apparatuses are provided for introducing high-pressure fluids or vacuum to a landfill conduit, for example, by means of the access port in the service conduit, to remove or dislodge obstructions. Conduits connected to blowers and pumps are used to introduce or withdraw fluids from the landfill conduits, for example, from predetermined locations within the landfill conduits identified by remote sensing devices.Type: GrantFiled: April 23, 2004Date of Patent: July 31, 2007Assignee: Landfill Service CorporationInventors: David L. Hansen, Dennis W. Super

Patent number: 7249608Abstract: The flow control device comprises a supply passage (2) for supplying hydraulic fluid discharged by a pump (1) to a power steering output section (8); a variable throttle section (3) situated at an intermediate position of the supply passage (2); and a flow control valve (4) for returning the hydraulic fluid in the supply passage (2) to the pump inlet side, in accordance with a pressure differential between upstream and downstream of the variable throttle section (3). When the pump (1) is halted, the flow control valve (4) is impelled by a spring (13) and closes the variable throttle section (3). A throttle passage (51) is provided for connecting the upstream side and the downstream side of the variable throttle section with the supply passage (2).Type: GrantFiled: October 7, 2004Date of Patent: July 31, 2007Assignee: Kayaba Industry Co., LtdInventors: Tetsuji Hayashi, Tsunefumi Arita, Hideyasu Ihira

Patent number: 7249610Abstract: For adjustment of a desired burner gas-air ratio over the broadest possible load range without additional pressure tapping of the burner, combustion chamber, or air lines, a ratio controller is provided that permits adjustment of the gas flow as a function of counterpressure. For adjustment, the ratio controller has at least one position-variable measurement site, or at least two measurement sites, connected directly or indirectly via a pilot valve, to an actuating diaphragm via a valve block or throttle valve block. Depending on whether the control pressure is picked up more from one or more from the other measurement site, the gas flow and therefore the gas-air ratio can be adjusted to be larger or smaller.Type: GrantFiled: August 27, 2004Date of Patent: July 31, 2007Assignee: Karl Dungs Gmbh & Co. KGInventor: Johann Moses

Patent number: 7249611Abstract: A top entry check valve including a valve body with an access port. A compressible hanger body engages a portion of the valve body and is positioned in alignment with the access port of the valve body. A clapper is connected to the hanger body so that the clapper is movable between a closed position wherein the clapper engages a valve seat to occlude the passage of fluid through the fluid flow passage and an open position wherein the clapper is moved away from the valve seat to permit passage of fluid through the fluid flow passage. A closure member is connected to the valve body to close the access port of the valve body. The closure member has an abutment surface engaging the hanger body so that the hanger body is compressed between the closure member and the valve body.Type: GrantFiled: November 9, 2006Date of Patent: July 31, 2007Assignee: Valve Innovations, L.L.C.Inventors: John P. Scaramucci, Danny Ray Lowe

Patent number: 7249614Abstract: A structure for reducing turbulence and increasing flow uniformity in a flowing fluid in a wind tunnel, or a fluid channel, has a plurality of conduits or channels arranged into a conduit bundle. The conduit bundle has a number of parallel conduits with plurality of perforations on the inner side walls of the conduit. As the fluid flows through the conduit bundle the sides of the conduits reduce lateral turbulence while the perforations minimize pressure gradients in the flowing fluid in adjacent conduits, resulting in isotropic turbulence. The invention is particularly useful in testing aircraft, improving engine performance, and fluid mechanics applications.Type: GrantFiled: July 20, 2004Date of Patent: July 31, 2007Inventor: Ahmad D. Vakili
