  • Patent number: 8876488
    Abstract: The present invention provides a device for turning off a pump. In operation, when the device is activated there is vacuum pressure in a syrup chamber. A diaphragm acting in response to the vacuum causes a piston assembly in the syrup chamber to move in the one direction (e.g. right), thus compressing a W-shaped spring in the air chamber. As the piston assembly moves, a spring holder of the W-shaped spring also moves to the one direction. As the W-shaped spring is compressed over and passed the most compressed position, the W-shaped spring moves a valve assembly in the air chamber to an opposite direction (e.g. left) and blocks a hole in a spool that otherwise allows air to pass through the air chamber to activate the pump. When the air is stopped, this turns off the pump.

  • Publication number: 20140261749
    Abstract: A touch-free faucet provides control over flow and/or temperature by detecting object presence in one or more detection zones. In one embodiment, the faucet provides for continuous-flow water flow wherein the spout of the faucet pours water for a period of time regardless of whether an object is detected in a detection zone, such as the sink, during that time. The faucet may initiate continuous-flow based on the detection of an object in another detection zone, and may cause continuous-flow operation for a determined period of time based on the amount of substantially uninterrupted time during which an object is detected in a detection zone associated with initiating continuous-flow mode. Furthermore, the faucet may provide for user-programmable sensitivity affecting the amount of continuous-flow time that is determined based on the amount of time that the faucet detects object in the continuous-flow mode detection zone.

  • Patent number: 7416903
    Abstract: The present invention provides methods and apparatus for mixing samples in-line in a microfluidic system, comprising methods of and means for introducing a first fluid sample into a flow-tube at a first end at a first velocity via a first conduit; methods of and means for introducing a second fluid sample into the flow-tube at the first end at a second velocity, the second velocity different from the first velocity, via a second conduit, wherein the first fluid sample and the second fluid sample converge in the flow tube to form an interface; whereby the first fluid sample and the second fluid sample mix at the interface within the flow-tube, wherein fluid flow at the first end of the flow-tube is laminar and fluid flow at a second end of the flow-tube is laminar, and wherein the flow-tube has a constant diameter between the first end and the second end of the flow-tube.

  • Patent number: 7318912
    Abstract: Microfluidic devices capable of combining discrete fluid volumes generally include channels for supplying different fluids toward a sample chamber and means for establishing fluid communication between the fluids within the chamber. Discrete fluid plugs are defined from larger fluid volumes before being combined. Certain embodiments utilize adjacent chambers or subchambers divided by a rupture region such as a frangible seal. Further embodiments utilize one or more deformable membranes and/or porous regions to direct fluid flow. Certain devices may be pneumatically or magnetically actuated.

  • Patent number: 7195229
    Abstract: In a direct injection type automatic sampler, a sampling needle having a liquid sample collected from a sample vessel by using suction force of a pump is inserted into an injection port. Then, a flow path-switching valve is rotated to switch a flow path to make a flow of mobile phase liquid pass through a loop to thereby introduce the collected sample into a column. The injection port is directly incorporated in the flow path-switching valve.

  • Patent number: 7165569
    Abstract: The invention relates to a safety shut-off device for sections of fluid circuits, which in case of damage or the like, have to shut off from each other on safety considerations. The safety shut-off device includes two chambers with connections for the sections to be shut off from each other. The chambers are separated from each other by a piston and have two connections each, of which one is closed by closing elements with sealing force elements, when both chambers have the same pressure. Further, two actuating devices are provided which are functionally connected to the closing elements and the piston. When the piston is moved due to a pressure difference between the connections, the closing element in the chamber with the higher pressure opens the associated connection so that fluid can flow from a section with higher pressure into the other section with lower pressure.

  • Patent number: 7118910
    Abstract: A variety of elastomeric-based microfluidic devices and methods for using and manufacturing such devices are provided. Certain of the devices have arrays of reaction sites to facilitate high throughput analyses. Some devices also include reaction sites located at the end of blind channels at which reagents have been previously deposited during manufacture. The reagents become suspended once sample is introduced into the reaction site. The devices can be utilized with a variety of heating devices and thus can be used in a variety of analyses requiring temperature control, including thermocycling applications such as nucleic acid amplification reactions, genotyping and gene expression analyses.

  • Publication number: 20030196695
    Abstract: Various microfluidic flow control devices are provided. In one embodiment, a regulating device includes overlapping channel segments separated by a deformable membrane in fluid communication with one another. In another embodiment, a normally open microfluidic valve provides latching valve operation with at least one adhesive surface. A stencil-based microfluidic valve may be operated by deforming a membrane against a seating surface to prevent flow through an aperture. Configurable microfluidic devices permit flow control among an interconnected microfluidic channel network. Magnetic elements may be integrated into flexible membranes to provide magnetically actuated microfluidic flow control device.

  • Patent number: 6571817
    Abstract: A pressure proving gas valve insures safe and efficient operation of a fuel-burning appliance by monitoring combustion air pressure and appropriately controlling the valve based upon this air pressure. An air pressure sensor is incorporated into a pressure proving valve housing itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber unless appropriate combustion air pressure is sensed. Further, by monitoring the actual air pressure, additional control capability is provided. That is, a variable speed blower associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.

  • Patent number: 6220270
    Abstract: An improved the velocity fuse valve controls communication between first and second brake valves and first and second brake lines. The velocity fuse valve includes a valve housing having a valve bore which slidably receives a valve spool. The spool moves in response to pressure in first and second pilot chambers, each communicated with a corresponding first and second outlet. The first pilot chamber is communicated with the first outlet via a first dashpot passage and a first orifice, and the second pilot chamber is communicated with the second outlet via a second dashpot passage and a second orifice. The orifices reduce or control how fast the spool will move in response to the pressure differential between the pilot chambers.
