20090250117 | SYSTEM FOR CREATING A WATER VOID DISPLAY - A liquid management system comprising a first chamber that has a first boundary wall, and a second chamber that has a second boundary wall. The second chamber has a base surrounded by the second boundary wall and the second boundary wall is within the first boundary wall. The second boundary wall height is lower than the first boundary wall height. The liquid management system also comprises a liquid level control module for controlling i) a first level of the liquid within the first chamber, and ii) a second level of the liquid within the second chamber. The liquid level control module is operable to lower the second level of the liquid in the second chamber below the second wall height while concurrently maintaining the surface level of the liquid in the first chamber higher than the second wall height such that the liquid within the first chamber flows over the second boundary wall from the first chamber into the second chamber to form a void in the liquid, the void has liquid sides inside the second boundary wall. | 10-08-2009 |
20100224263 | VARIABLE CAPACITY FUEL TANK - A fuel tank assembly is fillable by a fuel pump. The fuel pump is configured such that the existence of a predetermined condition causes the pump to stop delivering fuel. The fuel tank assembly includes a tank defining a chamber, a fill tube, and a fuel pump shut-off system. The fill tube defines an opening configured to receive a nozzle of the pump, and a passageway that provides fluid communication between the opening and the chamber to transfer liquid fuel from the nozzle to the chamber. The fuel pump shut-off system is configured to selectively generate the predetermined condition, and is configured such that whether the predetermined condition exists depends on the total volume of liquid fuel in the chamber and the chemical composition of the liquid fuel in the chamber. | 09-09-2010 |
20160004259 | APPARATUS AND METHOD FOR SELF-REGULATING FLUID CHEMICAL DELIVERY - Methods and apparatus for chemical delivery are provided herein. In some embodiments, a first reservoir holds a first volume of fluid, receives a carrier gas, and outputs the carrier gas together with vapor derived from the first volume of fluid. A second reservoir holds a second volume of fluid and is capable of delivering a part of the second volume of fluid to the first reservoir. A self-regulating tube extends from the first reservoir to a region above the second volume of fluid in the second reservoir. | 01-07-2016 |

20090044866 | Auxiliary Fuel Pump - An auxiliary fuel pump is mounted external to a fuel tank within the body of a vehicle. The auxiliary fuel pump is connected to a transfer hose for transferring fuel from a fuel tank in the vehicle to another location. | 02-19-2009 |
20100163114 | MICRO MIXER - A micro mixer including a first tubular member for guiding a first fluid to be directed in a first direction; a second tubular member having a discharge portion in the downstream portion of said first tubular member for guiding a second fluid to be directed in a direction opposite to said first direction, said discharge portion having a flow passage space narrower than the flow passage space of the downstream portion of the first tubular member; a first annular space defined by the downstream portion of the first tubular member and the discharge portion of the second tubular member for guiding a mixed fluid caused by colliding the first fluid flowing in the first tubular member with the second fluid flowing in the second tubular member in a counter-flow manner to be directed in the same direction as said first direction and further for increasing the pressure of said mixed fluid; a mixing-promoting space communicating with said first annular space for lowering the pressure of the mixed fluid discharged from said first annular space to promote mixing of the mixed fluid with the aid of vortexes caused in connection with the pressure drop of the mixed fluid; and a third tubular member for guiding the mixed fluid in said mixing-promoting space into a predetermined collecting unit. | 07-01-2010 |
20110146808 | Bi-Directional Valve with Cavity Pressure Relief - A valve operable to control flow between two adjacent pipe sections and having a system for relieving pressure from an enclosed cavity within the valve. The valve includes a first pressure port, a second pressure port, and a seal. When the valve is closed, the first pressure port is in fluid communication with one pipe section and the second pressure port in fluid communication with the enclosed cavity. The seal isolates the second pressure port from the first pressure port when fluid pressure within the enclosed cavity is less than a pre-selected valve and is displaceable to enable fluid communication between the second pressure port and the first pressure port when fluid pressure in the enclosed cavity is equal to or greater than the pre-selected value. | 06-23-2011 |
20110226346 | ACCUMULATOR WITH SOLENOID VALVE - An accumulator includes a canister, a piston, a sleeve, and a solenoid control valve assembly. The canister has an inner surface that defines an interior volume. The piston is slidably disposed within the interior volume of the canister. The piston is located between the inner surface of the canister and an outer surface of the sleeve. The piston divides the interior space into a fluid filled chamber and an air filled chamber. A fluid pathway is created by an outer surface of the sleeve and the inner surface of the canister. The fluid pathway allows fluid from an exterior source to either enter or exit the fluid chamber. The solenoid control valve assembly includes a valve body, a valve biasing member, and a plunger that is slidable within a recess of the valve body. | 09-22-2011 |
20130008522 | FLUID DISPENSING APPARTUS AND METHOD - A fluid dispenser and method of operating the same. The fluid dispenser can include a wheel driven by diluent passing along a flow path in the fluid dispenser. The wheel can be connected to a pump to pump fluid from a reservoir for dispense into the diluent. In some embodiments, the ratio of wheel rotations to pump cycles is selected to provide a desired and repeatable dilution ratio of concentrated fluid to diluent. The fluid dispenser can be portable and/or disposable, and in some embodiments is adapted for installation on an upper rim of a reservoir wall. Also, the fluid dispenser can be provided with a baffle limiting the velocity and impact of incoming diluent to the wheel driving the pump, thereby improving dosing accuracy of the dispenser in some embodiments. | 01-10-2013 |

20140174557 | Stagnant Fuel Thermal Insulation System - A method and apparatus for insulating a fluid line in a container configured to contain a fluid. The apparatus comprises a container, a fluid line in the container, and a tube. The container is configured to contain a fluid. The tube is placed around the fluid line in the container to form a channel around a first portion of the fluid line. The tube is configured to contain the fluid from the container in the channel and to prevent a first flow of the fluid between the container and the channel except through a number of ends of the tube. The tube is further configured to reduce a second flow of the fluid within the channel such that the fluid in the channel insulates the fluid line. | 06-26-2014 |
