This in-line active and reverse calculating mass balance blending system can maintain a chemical at desired control points, such as with respect to concentration, temperature, and/or pressure, while the output flow rate is changing dynamically to a point of use. A blending unit is configured to receive and blend at least two species and deliver a mixture at selected concentrations to points of use. A controller can be configured to determine a mass balance to maintain the concentrations in the mixture using information from metrology systems and a flow in an output to the at least one point of use. The controller also can be configured to maintain a concentration in the mixture within a concentration range by controlling flow rates to the blending unit.

An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material. The method of use also includes connection of a transfer set to a housing in a manner that further ensures optimum efficiency and safety.

The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.

A flow control device comprises a laminate structure of an electroactive material layer and a non-actuatable layer. An array of orifices is formed in one of the layers wherein the orifices are open in one of the rest state and actuated state and the orifices are closed in the other of the rest state and actuated state. Actuation of the electroactive material layer causes orifices to open and close so that flow control function may be implemented.
