These fluidic devices are analogous to electronic integrated circuits fabricated using large scale integration (LSI). A component of these networks is the fluidic multiplexor, which is a combinatorial array of binary valve patterns... Agent: Townsend And Townsend And Crew, LLP

20080029168 - Multi-port fluid distribution: The invention relates to a fluid distribution apparatus and method. The various embodiments of the fluid distribution apparatus comprise a core and a housing by which at least two input fluid streams may be selectively directed through two or more input ports to two or more output ports such that... Agent: Luedeka, Neely & Graham, P.C.

20080029170 - Three-in-one valve and control system: The present invention relates to a three-in-one valve comprising an inlet shutoff valve for shutting off flow to an inlet of the valve, an outlet shutoff valve for shutting off flow into an outlet of the valve and a control valve for opening and closing the valve. During operation, the... Agent: Mathews, Shepherd, Mckay, & Bruneau, P.A.

20080029171 - Flow restricted seat ring for pressure regulators: A control device includes a valve body, a seat ring, and an actuator. The valve body defines a flow-path for a fluid. The seat ring is disposed within the flow-path. The actuator is coupled to the valve body and includes a control member. The control member is adapted for displacement... Agent: Marshall, Gerstein & Borun LLP (fisher)

20080029172 - Integrated pressure proof fluid container with flexible pipe connectors: A fluid device that provides one or more features selected from being substantially tamper-resistant, substantially fluid-tight, and/or capable of providing stress relief to the various components used to form the fluid device. The fluid device accomplishes one or more of these features through the use of an injection material that... Agent: Sabic - 08ct Sabic Innovative Plastics -IPLegal

20080029173 - Variable flow reshapable flow restrictor apparatus and related methods: Disclosed in a novel apparatus and associated methods for controlling the flow around a reshapable flow restrictor. The flow restrictor reshapes as a function of the pressure differential within the flow restrictor. Small changes in the pressure differential allow for larger changes in the flow rate over conventional flow restrictor... Agent: Greenberg Traurig LLP (la)

20080029174 - Fluid control device: A fluid control system with easy installation in a semiconductor production system etc. and pipe and wiring connections, with reduced pressure loss due to pipe connections, with easy change of arrangement of modules, free from corrosion even using a corrosive fluid for the fluid, and enabling control of the flow...
