摘要： A spa chair having an apparatus for extending and retracting a tray from the spa chair is disclosed along with a method for utilizing the spa chair in one or more manicure and/or pedicure procedures. A pivoting mechanism coupled to the tray includes first attaching members for attaching the pivoting mechanism to the spa chair and a second attaching member for attaching the pivoting member to a tray. The pivoting mechanism also includes a shaft retained by the first attaching members and a spring for biasing a shaft and second attaching member in a particular direction. The pivoting mechanism is operable to lockingly secure the tray in at least one of an extended or retracted position.

摘要： A distributed amplifier may include an input transmission line for receiving on an input end an input signal, and an output transmission line for outputting on an output end an output signal. A plurality of amplifier stages may be coupled between intermediate positions on the input and output lines. Feedback impedance may negatively feed back a signal on the output end of the output line to a second end of the input line spaced from the first end of the input line.

摘要： A method is provided for removing an inorganic ionic species or organometallic ion contaminant, or combination contaminants, including such as arsenic, chromium, bromide, bromate, perchlorate, and/or others from water which contains an unacceptably high concentration of the contaminant(s). The method includes treating the water with an ion exchange resin, preferably a magnetic ion exchange resin such as MIEX® Resin, which is capable of adsorbing the inorganic ionic species contaminant(s), and regenerating and recycling the ion exchange resin back to the process. The method produces potable water from ground water containing such contaminants and eliminates breakthrough and chromatographic peaking problems observed with conventional ion exchange systems.
摘要翻译：提供了一种用于从含有不可接受的高浓度污染物的水中去除无机离子物质或有机金属离子污染物或组合污染物的方法，包括诸如砷，铬，溴，溴酸盐，高氯酸盐和/或其它物质的混合污染物，。该方法包括用离子交换树脂处理水，优选是能够吸附无机离子物质污染物的MIEX树脂等磁性离子交换树脂，并将离子交换树脂再生并再循环回的过程。该方法从含有这些污染物的地下水中产生饮用水，并消除了常规离子交换系统观察到的突破和色谱峰值问题。
