Abstract: A controller for use in a system employing selective permeable membrane technology to maintain a controlled atmosphere within a refrigerated container. The controller is electrically interfaced to an oxygen and carbon dioxide sensing device which is disposed within the container and capable of withstanding severe environmental conditions to measure the levels of oxygen and carbon dioxide within the container. The controller maintains preset levels of oxygen and carbon dioxide within the container and is adapted to calibrate the carbon dioxide and oxygen sensing devices as well as check for proper operation of the sensing devices and default to safety conditions when a failure is detected. The controller is further adapted to control the atmosphere maintenance system in a manner adapted not to increase the peak power requirements of the system.

Abstract: A device for maintaining a controlled atmosphere within a sealed container. The device is utilized to control the oxygen and the carbon dioxide levels within the container and utilizes permeable membrane technology to control such levels. An oilless compressor is used in conjunction with the device so as to not subject the permeable membranes to the derogatory effects associated with the presence of oil within an airstream that circulates through the permeable membranes. Additionally, the compressor is preferably mounted within the sealed container so as to not subject the compressor to the effects of temperature variation and corrosive marine environments. The present device further includes an air sampling system which is used to periodically measure the oxygen and carbon dioxide levels within the container. Control logic is included with the system which is operable to adjust the oxygen and carbon dioxide levels in accordance with the particular readings obtained by the sampling system.

Abstract: A modular multi-channel automated medical analyzer device is disclosed, characterized by use of an ion selective electrode and/or enzymatic electrode/wash cell system which permits rapid analysis of various substances of interest contained within undiluted body fluids such as whole blood, serum and/or plasma. The ion selective electrode and/or the enzymatic electrode are disposed upon a probe which automatically axially reciprocates downwardly in a simple manipulative motion between an open-ended reference wash cell and a sample cup bearing the body fluid specimen to be analyzed. The wash cell includes an inlet port and one or more outlet ports through which is circulated an aqueous solution bearing a known concentration of the substance to be measured to provide a reference calibration medium as well as a probe washing medium. The probe is lowered directly into the sample cup to physically contact the specimen to be measured and, after analysis, is lifted upwardly into the wash cell wherein any attendant portion of the specimen remaining on the probe is stripped off by suction and the aqueous solution flow through the wash cell is initiated to thoroughly wash the probe and establish a new calibration medium for subsequent specimen analysis. The wash cell/probe assembly is specifically designed to prevent any leakage or drooling of the aqueous solution from the wash cell into the sample cup throughout manipulation of the probe. Operation of each of the modules of the analyzer is facilitated through common processing and control electronics and test measurements are accomplished initially on a dual point calibration procedure and subsequently on a single point calibration procedure.

Abstract: There is disclosed a purging system for removing foreign matter from a fluid conducting conduit in which a sensor detects the presence of the foreign matter and produces an electrical signal which activates a timer which, in turn, connects a pump to the conduit for a given time duration to purge the conduit of the foreign matter. A counter also maybe connected to periodically activate the timer and purge the conduit, whether or not the sensor has detected foreign matter.

Abstract: The present invention is a system for maintaining a controlled oxygen atmosphere within a transport container vessel, such as a bulk rail car through the use of permeable membrane technology. An oilless compressor is used in conjunction with the system so as not to subject the permeable membranes to the derogatory effects associated with the presence of oil within an air stream that circulates through the permeable membranes. The present system further includes an air-sampling system which is used to continuously measure the oxygen levels within the rail car so as to provide verification that the oxygen levels are maintained at 5% or less to kill insects, larvae, or eggs which may be within the bulk materials transported by the rail car.
