摘要: An analyzer for chemical assays includes a turntable which supports sample containers and reagent containers within a cooled volume and test cells about the periphery of the cooled volume. A probe is carried by a rotating arm for withdrawing liquid from the containers and dispensing the liquid. Fixed stations are also provided in the path of the probe. One such station serves to both wash the tip of the probe and to receive samples for flow-through analysis. Heaters associated with the probe and with the test cells increase the rate of reaction. Curved walls of test cell segments match the optics of an optical analyzer so that light from the analyzer lamp is generally orthogonal to the curved surfaces. The light voltage of the lamp may be controlled as a function of lamp wavelength required for particular assays. The system provides multiple-point calibration and automatic dilution of samples.

摘要: A process environment monitoring system collects and tests air samples from a number of different sample locations. Each sample is drawn into a sample test chamber into which a beam of infrared light is directed from an infrared source. The beam is reflected off mirrors in the test chamber a number of times before it exits and is directed to an infrared detector. The detector identifies absorption peaks in the spectrum of the infrared beam to determine the presence of certain gases of interest in the test chamber. A host computer is provided to function in conjunction with a valve controller to make up a data processing unit. The data processing unit services a number of tasks to make the process environment monitor a fully integrated system. The system controls employee identification, alarm triggering, and automated system control, as well as a number of other functions. Different system access levels are provided, and identification and access level information may be input by the reading of an employee identification card by a magnetic card reader.

摘要: A combination of substantially unmixed fluid materials which are flowing under conditions which normally result in laminar (non-turbulent) flow are mixed by passing the fluids upwardly into a chamber containing a heavy ball which is levitated above the chamber inlet by the flow of the fluids, resulting in an intimate mixing of the fluids.
