Abstract: An apparatus for replacing transmission fluid in an automatic transmission. The apparatus comprises a tank separated into a pair of compartments by a bladder or diaphragm. At least one pressure regulator communicates with the tank. A vent valve assembly also communicates with the tank. A process for cleaning an automatic transmission and for replacing after cleaning used automatic transmission fluid in the automatic transmission with fresh automatic transmission fluid. The process includes flowing fresh ATF into a first compartment of a tank and into a pliable tub or bladder member in communication with the first compartment until the pliable tub or bladder member and the first compartment are filled with a volume of fresh ATF. A chemical cleaning compound is disposed in the used ATF of the automatic transmission and is circulated through the automatic transmission and its associated components to clean the same and produce contaminated used ATF.

Abstract: A flow cell for use in an analytical system of the type that may be used to test water samples for specific analytes. The flow cell reduces or eliminates the effects of backpressure on a liquid stream passing through the flow cell. This allows a sensor to be incorporated with the flow cell and enables the sensor to provide consistent output with respect to the analyte being tested without introducing signal error due to backpressure fluctuations.

Abstract: A pulse oximeter and method of determining the oxygen saturation level of a patient's blood wherein a heartbeat related signal is used, as a reference to guide the averaging of optical pulse waveforms. The oximeter and method assign different weighting to different optical pulses based upon the amplitude of new pulse waveforms and the degree of similarity between it and the preceding waveform. A composite, averaged pulse waveform is then used in computing oxygen saturation level.

Abstract: A gas multiple component analyzer includes an infrared source that passes at least one measuring beam through a sample cell that contains the gas to be analyzed. Three measuring signals are generated in response to the measuring beam, and each is indicative of optical energy from the source transmitted through the sample cell in a respective optical region characterized by a respective optical center wave-length and a respective band pass. The three measuring signals are algebraically combined to automatically determine which of the three end gases is present in the sample cell in the greatest concentration, and the concentration thereof. The disclosed system measures concentration of three separate gases having overlapping absorption spectra.
