    • A three step flow injection analysis method for determining the degree of neutralization of phenol in solution. The first step is to flow a stream of a carrier liquid, such as water, along one side of a two sided semipermeable membrane, such as a silicone rubber membrane. The second step is to flow a stream of water along the other side of the membrane to a detector, such as a flow through ultraviolet spectrometer, the detector being responsive to the concentration of the phenol in the flowing stream of water. The third step is to add a volume of the solution to the flowing stream of carrier liquid so that the solution is carried to the first side of the membrane where a portion of the phenol permeates across the membrane into the flowing stream of water to be detected by the detector, the degree of neutralization of the phenol in the solution being a function of the response of the detector. The results of the method are substantially unaffected by variations in the concentration of the phenol.
    • 用于测定溶液中苯酚中和度的三步流动注射分析方法。 第一步是沿着双面半透膜(例如硅橡胶膜)的一侧流动诸如水的载液的流。 第二步是沿着膜的另一侧流动水流到诸如流过紫外光谱仪的检测器,检测器响应于流动的水流中的苯酚的浓度。 第三步是将一定体积的溶液加入到流动的载体液体流中,使得溶液被运送到膜的第一侧,其中一部分酚渗透穿过膜进入被检测的水流中 通过检测器,溶液中苯酚的中和度是检测器响应的函数。 该方法的结果基本上不受苯酚浓度变化的影响。

    • Apparatus for stop flow membrane probe analysis which apparatus is especially suitable for on-line analysis, the apparatus necessarily including five parts. The first part is a reservoir for containing an extractant. The second part is a flow control unit, being a pump or valve, the flow control unit connected to the reservoir, the flow control unit being of the type that can be turned on and off. The third part is a flow through membrane probe, the flow through membrane probe being connected to the flow control unit. The fourth part is a detector, the detector being connected to the flow through membrane probe. The fifth part is a switch for turning the flow control unit on and off so that the apparatus can be used for stop flow analysis. Preferably, the detector is also connected with the reservoir so that the extractant flowing through the probe and detector can be. recycled back to the reservoir. The probe is immersed into a process stream. A component of interest of the process stream permeates across the membrane into the extractant to be detected by the detector.

    • An information display device has a display surface supported on a leg from the lower end of which one or more finger elements extend at a right angle to the display surface to detachably or permanently secure it to one of the jaws of a garment clamping hanger. The finger elements engage the rear jaw of the garment clamp in such a manner that the clamp will remain erect during handling of the hanger and its load and will not interfere with the loading and unloading of the hanger. While the fingers extend the length of the hanger, the display surface is positioned at a right angle thereto so the information of its display surface is visible from the end of the hanger.
    • 信息显示装置具有从其下端支撑在腿上的显示表面,其一个或多个指状元件以与显示表面成直角的方式延伸,以可拆卸地或永久地将其固定到衣服夹持衣架的一个夹爪上。 指状元件以这样的方式接合衣夹的后爪,使得夹具在处理衣架及其负载期间将保持直立,并且不会干扰衣架的装载和卸载。 当指状物延伸衣架的长度时,显示表面与其成直角定位,使其显示表面的信息从衣架的末端可见。

    • A hanger specifically designed for holding and suspending lightweight clothing, particularly delicate fabrics, has a rigid, elongated body terminating at each end in a pair of arms, one on top and one on the bottom of the body forming article receiving slots opening toward the center of the hanger. A third arm creates a downwardly opening slot at the end of the body. The arms are designed to permit limited flexing for seating and removing articles from the slots. The flexing occurs as a hinging action at the point of attachment to the body and at this point the arms are reinforced. The upper of the slots may have a pocket portion for positively securing garment straps and the like and also a finger member spaced from the inner end of the upper arm to form an upwardly opening entry to the slot or it may have a spring-like finger in the pocket which clamps a garment inserted into the pocket area. The downwardly opening end slots may have an upwardly extending finger to clamp a garment against the finger forming the outer side of the slot.

    • A hanger is made with a molded plastic body and a metal hook. The body has a vertical hole to receive the shank of the hook. The lower end of the hole communicates with an opening or pocket in the hanger body. The shank of the hook is provided with a diametrically enlarged head, the end of which is tapered. The cylindrical diameter of the shank is less than that of the hole and the diameter of the head is more than that of the hole. The hook is assembled by forcing or plunging the head and shank through the hole until the head seats in the opening. The resilience of the plastic of the hanger body restores the hole to its original diameter and a substantially radial shoulder formed by the top of the head seats against the top of the opening about the end of the hole supporting the body on and for free rotation about the hook. The substantially radial shoulder is canted at an oblique angle with respect to the radial direction and an annular area of reduced cross section is disposed between the shoulder and the cylindrical diameter of the shank.
