Methods for in situ mixing of two or more different liquid compositions by employing a dynamic flow profile characterized by a ramping-up section and/or a ramping-down section.

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.

Systems for producing, applying and evaluating coating compositions are disclosed. An automatic color matching system includes an automatic coating component dispenser, a container, a mixer for mixing the components of the coating composition and a solvent, an automatic pressurization station to apply pressure to the mixed coating composition, and a robotic arm to transport the container to and from the mixer. A coating composition dispensing system includes a computer to provide a target formulation for a coating composition, an automated component dispenser containing the components of the coating composition, a container positionable adjacent to the component dispenser to receive the components of the coating composition, and an automated component sensor to measure the amounts of each of the components dispensed into the container. The computer is programmed to store data corresponding to the measured amounts of each of the components, and amounts of components contained in the coating compositions may be monitored, along with processing parameters when the coating compositions are applied to various substrates. The characteristics of a produced sample coating may be compared with the characteristics of a target or reference coating to determine if they are sufficiently matched.
