Abstract: The present invention is a system for handling liquid and a method for the same. The system has a container capable of holding a liquid. An electronic storage device is coupled with the container for electronically storing information relating to the liquid stored in the container. The system also has an antenna, for storing information to and reading information from the electronic storage device. Finally, the system has a microprocessor-based controller, coupled with the antenna, for controlling processing of the liquid based on information read from the electronic storage device by the antenna.

Abstract: A secure reader system (SRS) for containers housing material to be employed in an application. A container is provided having an information storing mechanism. A connector of the SRS having a reader is provided to physically couple to the container for periodically reading information there from. The connector is configured to physically couple to the container and may draw material from the container simultaneous with the reading.

Abstract: The present invention relates to apparatus and method for re-circulating high viscosity liquids. The apparatus comprises a recirculating probe coupled to a fluid storage and dispensing vessel by a connector, and the recirculating probe comprises: (a) a dip tube defining an output flow path; (b) an output port; (c) a recirculating port; and (d) a return flow path. The output flow path and the return flow path preferably have substantially equal cross-sectional areas, which reduce or eliminate the unbalance between the discharge pressure in the output line and that in the re-circulation line, and prevent premature wearing-out of the dispensing/recirculating pump.

Abstract: The present invention is a system for handling high purity liquid and a method for the same. The system has a container with a mouth. The container is configured to hold liquid. A cap is coupled with the mouth of the container. A connector is coupled with the cap. The connector has a connector head and a probe extending from the connector head. The probe is insertable through the cap and through the mouth into the container. The probe has a flow passage. The system also has a pressurization source that communicates with the container. Pressure delivered from the source acts upon the container forcing liquid out of the container through the flow passage in the probe. There is also a pressurization port communicating with the connector, the cap, and the pressurization source. Pressure from the pressurization source is delivered to the container when the cap and the connector are properly mated.

Abstract: A chemical blending system for blending two or more constituent chemicals to a desired concentration. One embodiment of the system includes a mix tank, a recirculation line having an inlet and an outlet in the tank, and a pump in the recirculation line for recirculating and mixing the blended chemical. A source of diluent is fluidly coupled to the mix tank through a diluent inlet and supply line. A source of concentrated chemical is fluidly coupled to the recirculation line through a concentrated chemical inlet, supply line, and an adding valve located in the recirculation line between the inlet and pump. A conductivity-type sensor in the recirculation line provides continuous measurements of the blended chemical concentration. A titration analyzer is coupled to the recirculation line to provide periodic blended chemical concentration measurements. A programmable logic control system including a processor and associated memory is coupled to the adding valve, conductivity-type sensor and titration analyzer.

Abstract: Apparatus blending a diluent liquid, i.e., DI water, with a chemical concentrate, a flow duct and mixing tank forming a closed loop for mixing; a pair of flow duct portions each having a conductivity sensor inductively sensing chemical concentration in the blended liquid; a comparator for comparing the outputs of said parallel sensors; a single pump circulating blended liquid around the closed loop and drawing chemical concentrate from a source through an adding valve which cycles open and closed under control of the concentration sensors; the pump also propelling the blended liquid from the closed loop to the point of use, and conductivity sensors existing in individual housings through which the blended liquid flows upwardly to minimize any collection of bubbles adjacent the sensors.

Abstract: Empty drum detecting apparatus comprises an upright manifold chamber connected at its intermediate portion to a supply line extended to a supply drum of liquid chemical, and a pump for directing pumped liquid to process equipment utilizing the liquid chemical and having an inlet line. An outlet line is connected to the bottom portion of the upright manifold chamber and connected to the inlet line of the pump; and a shunt line with a flow restriction therein is connected between the upper portion of the manifold chamber and the outlet line for delivering collected gases and liquid to the inlet line and pump. An alternate flow restricting valve may be placed in the outlet line to restrict liquid flow from the lower portion of the manifold chamber. A capacitance proximity sensor is mounted above the inlet of the manifold chamber and senses the liquid level in the manifold chamber to produce an indication of the liquid level.
