    • The present invention is a method of preparing a high internal phase ratio emulsion without phase inversion comprising the steps of:a) continuously merging into a disperser and in the presence of an emulsifying and a stabilizing amount of a surfactant, a continuous phase liquid stream having a flow rate R.sub.1, and a disperse phase liquid stream having a flow rate R.sub.2 ; andb) mixing the merged streams with a sufficient amount of shear, and with R.sub.2 :R.sub.1 sufficiently constant, to form the high internal phase ratio emulsion without phase inversion or stepwise distribution of an internal phase into an external phase;wherein R.sub.2 :R.sub.1 encompasses a range, the lower limit of which range being defined by a point where the volume average particle size of the high internal phase ratio emulsion begins to show an inverse dependence on R.sub.2 :R.sub.1, and wherein the upper limit of which range is just less than an R.sub.2 :R.sub.1 where a phase inversion of the high internal phase ratio emulsion takes place.Monodisperse submicron particles can be prepared using the process of the present invention. Useful latexes can be prepared from these high internal phase ratio emulsions.
    • 本发明是一种制备不含相转化的高内相比乳液的方法,包括以下步骤:a)连续合并到分散器中,并在乳化剂和稳定剂量的表面活性剂存在下,连续相液体流具有 流量R1和具有流量R2的分散相液体流; 和b)将合并的流与足够量的剪切混合,并使R2:R1充分恒定,以形成高内相比乳液,而不会内相逐步分配到外相中; 其中R2:R1包含一个范围,其下限限定在高内相比乳液的体积平均粒径开始显示与R2:R1的反相关性的点,其中其上限 范围小于R2:R1,其中发生高内相比乳液的相转化。 可以使用本发明的方法制备单分散亚微米颗粒。 可以从这些高内相比乳液制备有用的胶乳。

    • This invention relates to a float controlled dispenser for automatically releasing predetermined amounts of a detergent or a bacteriostatic liquid into the flush tank of a toilet bowl whenever the bowl is flushed. The dispenser comprises a bottle necked container mounted in an inverted position in the flush tank and a dispensing valve assembly consisting of a plug having a tapered end and force fitted into the neck portion of the bottle, said plug having a central orifice circumscribed by an annular planar valve seat and of a bell shaped float member having an annular measuring chamber in which is centrally located a vertical fluted stem projection for limiting the float's up and down movement within the plug's central orifice. The base of the stem projection is circumscribed by an annular planar surface for sealing contact with the plug's planar annular surface. The end of the vertical stem projection has an enlarged cross-section to retain it in the plug's central orifice to allow the float member to descend to a position such that the top edge of the measuring chamber substantially coincides with the plug's annular surface. The outer surface of the float member is provided with longitudinal ribs to guide the float member in its up and down movement within the plug, the ends of said ribs being tapered inwardly to conform to the internal tapered surfaces of the plug. For shipping purposes, the dispenser is also provided with a disposable cap threaded over external threads on the bottle neck.
    • 本发明涉及一种浮子控制的分配器,用于在碗被冲洗时,将预定量的洗涤剂或抑菌液体自动释放到马桶的冲洗槽中。 该分配器包括一个瓶颈容器,该容器以倒置的位置安装在冲洗槽中,以及一个分配阀组件,该组件由具有渐缩端和插入瓶子颈部的力的插塞组成,所述插塞具有由环形 平面阀座和具有环形测量室的钟形浮子构件,其中在其中心定位有垂直槽纹的杆突起,用于限制浮子在插塞的中心孔内的上下运动。 杆突起的底部由环形平面表面限定,用于与塞的平面环形表面密封接触。 垂直杆突起的端部具有放大的横截面以将其保持在插塞的中心孔中,以允许浮子构件下降到使得测量室的顶部边缘基本上与塞子的环形表面重合的位置。 浮子部件的外表面设置有纵向肋条,以引导浮子部件在塞子内的上下运动,所述肋部的端部向内锥形以与塞子的内部锥形表面一致。 对于运输目的,分配器还具有螺纹穿过瓶颈上的外螺纹的一次性盖。
