    摘要: A ratiometric method for using optical sensors is provided to measure dissolved oxygen in a fluid sample. The sensor is formulated so as to contain an oxygen permeable membrane of a cured perfluorinated urethane polymer and, incorporated therein, an oxygen-sensitive indicator component and a reference dye component. The emission spectrum from the indicator component is calibrated by comparison with that of the reference dye, which is substantially less sensitive to oxygen-quenching and which has a photodecomposition rate similar to the indicator component. Methods for making and using the membrane and sensor are provided as well.

    摘要: A PCV circuit for an internal combustion engine is modified to deliver the PCV fluid to an atomization chamber which also receives fuel from an electronic fuel injector tapped into the main vehicle fuel supply. The fuel from the injector is thoroughly vaporized in and/or immediately downstream of the chamber and conveyed to the vehicle intake manifold. A switch cuts off operation of the fuel injector at high load/high throttle setting conditions. The injector operates at a constant frequency with a selected ON time.

    摘要: Continuous breakpoint halogenation with hydroxyl free radical species is used to increase the rate of sanitization a water system and maintain a high rate of oxidation in the bulk water of the pool, spas, and other water systems despite the presence of accumulated demand. Undesirable compounds can be eliminated by maintaining a level of desired oxidation potential. The feedrate and ratio of halogen donor and free radical species can be optimized to sustain the desired ppm range of halogen and sustain an ORP of, for example, 780 mV-820 mV. Sustaining these parameters can prevent or even reverse the accumulation of combined halogen and other halogenated volatile compounds, which can contaminate the air and water of water facilities such as indoor swimming pools.

    摘要: An apparatus for generating free radical species can be used to sanitize water systems. The apparatus generates hydroxyl free radical species using substantially pure water, or using a liquid that is substantially free of oxygen-reactive species, to maximize free radical species generation to sanitize the water system. The free radical species are generated by ultraviolet radiation having a wavelength of less than or equal to 254 nm.
