    摘要： A device for use in a swimming pool to continuously dispense chlorine for sanitizing the water is disclosed which has a metering valve designed for precise adjustment of the rate of dispersion of the chemical contained in the feeder. The metering mechanism is made of two segments, with a metering valve cap fitting over a metering valve body to adjust the apertures in the metering mechanism. Precise control is afforded both by a screw-type adjustment of aperture size and by a prevention of inadvertent readjustment of the metering mechanism caused by the device being bumped.

    摘要： A device for use in a swimming pool to continuously dispense chlorine for sanitizing the water is disclosed which provides an indication when the device has either depleted or nearly depleted its chlorine supply. The float supporting the feeder and the chlorine is of two colors, one color on the top and a second color on the bottom. When an adequate amount of chlorine is contained in the feeder, the bottom color is below the waterline and not readily visible, and when the chlorine is depleted to a desired minimum amount, the bottom color is sufficiently above the waterline to provide a readily perceived visual warning of chlorine depletion.

    摘要： Disclosed is a method for purifying Human interleukin-5 (IL-5) a single chromatographic step. After removing cells from a cell culture expressing human interleukin-5, IL-5 is purified by first adjusting the culture supernatant to the calculated pI value of mature IL-5 (pI=7.44) and then passing the conditioned supernatant through tandem linked anion- and cation-exchange columns. The resulting pass-through fraction contains the IL-5 and is devoid of all other contaminating proteins. An optional hydrophobic-interaction chromatography step is disclosed for positive selection of IL-5 and in order to concentrate the preparation. Pure IL-5 was recovered with a high overall yield (>90%), was N-glycosylated and was entirely homodimeric.
