Abstract:
Disclosed herein is a device and method for changing the conditions of a solution flowing in a serial path. In particular, disclosed herein is a device that includes a chemical reactor, a first system, and a second system that are each serial to one another. Each of the first system and the second system include a mixing chamber, a solvent reservoir, a solvent pump, and one or more detectors. Also disclosed herein is a method for changing the condition of a solution that includes flowing a liquid sample in a path, serially mixing the sample with at least two discrete solvents while it flows through the path, and detecting the condition of the sample after it is mixed with each solvent.
Abstract:
A polyester production system employing a vertically elongated esterification reactor. The esterification reactor of the present invention is an improvement over conventional CSTR esterification reactors because, for example, in one embodiment, the reactor requires little or no mechanical agitation. Further, in one embodiment, the positioning of the inlets and outlets of the reactor provides improved operational performance and flexibility over CSTRs of the prior art.
Abstract:
An electrolyzer which decomposes distilled water into a new fuel composed of hydrogen, oxygen and their molecular and magnecular bonds, called HHO. The electrolyzer can be used to provide the new combustible gas as an additive to combustion engine fuels or in flame or other generating equipment such as torches and welders. The new combustible gas is comprised of clusters of hydrogen and oxygen atoms structured according to a general formula H m O n wherein m and n have null or positive integer values with the exception that m and n can not be 0 at the same time, and wherein said combustible gas has a varying energy content depending on its use.
Abstract:
Parallel flow reaction systems comprising four or more reaction channels are disclosed. Distribution systems, and parallel flow reaction systems comprising such distribution systems are also disclosed. Specifically, the distribution systems comprise one or more subsystems, including for example, a flow-partitioning subsystem for providing a different flow rate to each of the four or more reactors, a pressure-partitioning subsystem for providing a different reaction pressure in the reaction cavity of each of the four or more reactors, and a feed-composition subsystem for providing a different feed composition to each of the four or more reactors. In preferred embodiments, the one or more subsystems can comprise at least one set of four or more flow restrictors, each of the four or more flow restrictors having a flow resistance that varies relative to other flow restrictors in the set.
Abstract:
A microfluidic device interface (32) for a microfluidic device (12) has a work surface (102) and a microfluidic mounting device assembly (104) coupled to the work surface (102). A plurality of fluid sources (54) are provided having various reagents therein. A manifold (274, 276, 278, 280) fluidically couples the microfluidic device (12) to the fluid sources (54). A plurality of valves (56) are fluidly coupled to a respective fluid source (54) for controlling a fluid flow to the microfluidic device (12).
