Patent number: 8176934Abstract: Valve control assemblies are disclosed which accommodate out of plumb conditions using a flexible set of rings linked to the temperature control, and a projection/axial slot arrangement linked to the volume control. Different wall thicknesses are accommodated using one or more adaptors/extensions between a temperature bonnet control and a portion of the valve cartridge which controls temperature. There is also a combined shroud/tool for protecting the valve during rough-in and permitting it to be tested.Type: GrantFiled: May 20, 2008Date of Patent: May 15, 2012Assignee: Kohler Co.Inventor: Michael A. Niver

Patent number: 8176937Abstract: A temperature adjustable water mixing valve having a cold water inlet, a cold water outlet, a hot water inlet, a mixing water outlet, and a valve core configured to open or close water channels. The temperature adjustable water mixing valve further includes a pressure relief channel between the cold water inlet and a port connected with a water storage device. The channel is equipped with a check valve allowing water to flow from the water storage device to the cold water inlet. The temperature adjustable water mixing valve opens the check valve to discharge toward the front-end water source when the inner pressure in the water storage device is high.Type: GrantFiled: March 31, 2009Date of Patent: May 15, 2012Assignee: AOS Holding CompanyInventors: Liping Zhang, Huaxin Wan, Bu Qiu, Lan Zhang

Patent number: 8176951Abstract: A system and method are provided for in-line processes of blending butane into gasoline streams, and for blending butane into a gasoline stream at any point along a petroleum pipeline. The invention additionally provides a method for measuring the vapor pressure and vapor to liquid ratio of the gasoline, both upstream and downstream of the blending operation, as well as the sulfur content of the butane entering the blending operation. The blending operation can be controlled to ensure that the blended gasoline meets EPA requirements for vapor pressure and sulfur content of gasoline. The invention further provides a method for accessing and monitoring the operation off-site.Type: GrantFiled: December 8, 2009Date of Patent: May 15, 2012Assignee: Sunoco Partners Butane Blending LLCInventors: Larry D. Mattingly, Steven M. Vanderbur

Patent number: 8162003Abstract: A fuel valve includes a housing defining a ported standpipe portion for extending upwardly into a fuel tank at a bottom opening thereof. The standpipe sealingly receives a ported and relatively rotational valving member, which also carries a respective resilient sealing collar aligned with and sealingly cooperating at each of the ports of the valving member. The valving member is selectively rotational and may be positioned relative to the standpipe portion in order to stop fuel flow through the valve, or to selectively allow fuel flow through the valve from one or more separate levels of fuel in the fuel tank. A handle on the exterior of the fuel valve provides for selective rotation and positioning of the valving member, and the fuel valve itself may be selectively and conveniently rotated relative to a fuel nipple attached to the fuel tank.Type: GrantFiled: January 26, 2005Date of Patent: April 24, 2012Inventor: Damian Gregory

Patent number: 8156963Abstract: A faucet includes a spout body formed by joining an upper body and a lower body to one another. A one-piece spout tube is secured to the upper body. For example, only a cartridge seat and an aerator of the faucet are used to hold the spout tube in the upper body. Water supply hoses connected to the cartridge seat bring hot and/or cold water from a water supply source to a valve cartridge interfaced with the cartridge seat. The water flows from the water supply source, through the water supply hoses, the cartridge seat, the valve cartridge, and the spout tube, and out the spout body through the aerator. The valve cartridge allows a user to control a flow rate and/or temperature of the water delivered through the spout tube and out the spout body.Type: GrantFiled: December 24, 2008Date of Patent: April 17, 2012Assignee: Moen IncorporatedInventors: Darren S. Lopp, William E. Patton

Patent number: 8127792Abstract: A pipeline flow meter orifice fitting includes a first body, a flow bore through the first body, a chamber in the first body adjacent to the flow bore, an orifice plate supported in alignment with the flow bore by an orifice plate carrier, wherein the orifice plate carrier is exposed to the chamber and divides the flow bore into a first region to one side of the orifice plate and a second region to the other side of the orifice plate, a second body coupled to said first body, a first flow path fluidicly coupling the first region and the chamber through the second body, and a second flow path fluidicly coupling the second region and the chamber through the second body. In some embodiments, a three way valve is mounted on the first body, the three way valve selectably actuatable to open a first flow path between the first region and the chamber or a second flow path between the second region and the chamber.Type: GrantFiled: July 30, 2008Date of Patent: March 6, 2012Assignee: Daniel Measurement and Control, Inc.Inventor: Thomas Henry Loga
