    • An adsorbent filter for removing caffeine from liquids. The filter is composed of a matrix of fibrous material; and adsorbent particulate material integrated within the matrix of fibrous material, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. The adsorbent material may be clay minerals such as, for example, smectite clay minerals. Examples of smectite clay minerals include, bentonite clays and montmorillonite clays. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.
    • 用于从液体中去除咖啡因的吸附剂过滤器。 过滤器由纤维材料基体组成; 以及整合在纤维材料基质内的吸附剂颗粒材料,使得咖啡因浓度范围为每100mL液体约20至约100mg的液体通过基质,接触时间小于约2分钟,导致 咖啡因浓度至少降低40%。 纤维材料的基质可以选自机织织物,针织织物和非织造织物。 吸附剂材料可以是粘土矿物,例如蒙脱石粘土矿物。 蒙皂石粘土矿物的实例包括膨润土和蒙脱石粘土。 一般来说,过滤器可以适合于提供约1杯至约40杯液体的咖啡因浓度的至少40%的降低。

    • Disclosed is a process for disinfecting water which provides a visual indication after the disinfection is complete. First, the water to be disinfected is generally simultaneously intermixed with at least three items. The items are: (1) a disinfectant which is adapted to render harmless substantially all pathogens present in the water upon the disinfectant being intermixed with the water for a time period T.sub.k ; (2) a colorant; and (3) a material which can remove substantially all of the disinfectant and colorant from the water over a time period t.sub.r, where T.sub.r is greater than T.sub.k. Secondly, the water, disinfectant, colorant and the removing material are allowed to remain intermixed for a time period of T.sub.r or greater. At the end of the time period T.sub.r, substantially all pathogens in the water will be rendered harmless, substantially all of the disinfectant will be removed from the water and substantially all of the colorant will be removed from the water. As a result of the removal of the colorant, the water will become uncolored which will give the consumer a visual indication after the disinfection process is complete and the water is safe to drink. Articles for use in carrying out the process are also disclosed.
    • 公开了一种消毒水的方法,其在消毒完成后提供视觉指示。 首先,要消毒的水通常同时混合至少三个物品。 这些项目是:(1)消毒剂,其适于使消毒剂中存在的基本上所有病原体与水混合一段时间Tk; (2)着色剂; 和(3)在Tr大于Tk的时间段tr内可以从水中大量除去基本上所有的消毒剂和着色剂的材料。 其次,允许水,消毒剂,着色剂和去除材料保持混合Tr或更长时间。 在时间段Tr结束时,水中的基本上所有的病原体将变得无害,基本上所有的消毒剂将从水中除去,并且基本上所有的着色剂将从水中除去。 由于着色剂的去除,水将变得无色,这将在消毒过程完成并且水安全饮用后给消费者一个视觉指示。 还披露了用于执行该过程的物品。
