    • The invention relates to a medical gripping and/or cutting instrument with an instrument shaft (1), with a handle (3) that can be fixed movably on the instrument shaft (1), and with a tool (2) mounted on the distal end of the instrument shaft (1) and consisting of two jaw member (2a, 2b), where at least one jaw member (2a or 2b) of the tool (2) can move in relation to the other jaw member (2b or 2a). In order to provide a medical instrument that, along with good cleaning properties and compact structure, also ensures simple and safe operation, the invention proposes that the handle (3) should include a coupling mechanism both to fix the handle (3) to the instrument shaft (1) and also to operate the at least one movable jaw member (2a or 2b) of the tool (2).
    • 本发明涉及一种具有仪器轴(1)的医疗夹持和/或切割仪器,其具有能够可移动地固定在仪器轴(1)上的手柄(3),以及安装在远端的工具(2) 仪器轴(1)的端部并且由两个钳口构件(2a,2b)组成,其中工具(2)的至少一个钳口构件(2a或2b)可相对于另一钳口构件移动 (2b或2a)。 为了提供一种具有良好的清洁性能和紧凑结构的医疗仪器,也确保了简单和安全的操作,本发明提出手柄(3)应包括将手柄(3)固定到仪器上的联接机构 轴(1),并且还操作工具(2)的至少一个可移动夹爪构件(2a或2b)。

    • A method for a liquid-liquid extraction of hydrophilic organic compounds from aqueous solutions thereof is described. The method generally includes intermixing a sufficient quantity of a specified glycol ether with the aqueous liquor at a first temperature to form a suspension comprising an aqueous raffinate phase and a glycol ether extract phase; separating the glycol ether extract phase from the aqueous raffinate phase; heating the glycol ether extract phase to a second, higher temperature to form a suspension comprising an aqueous extract phase containing a portion of the hydrophilic organic compound and a glycol ether raffinate phase; and separating this glycol ether raffinate phase from the aqueous extract phase. The selected glycol ether has an inverse solubility in water and the partition ratio, value K, for the hydrophilic organic compound is greater than 0.1. This method is useful for recovering valuable hydrophilic organic acids produced via fermentation or produced or used in various manufacturing processes.
    • 描述了从其水溶液中液 - 液萃取亲水性有机化合物的方法。 该方法通常包括在第一温度下将足够量的特定二醇醚与含水液体混合以形成包含残液相和二醇醚萃取相的悬浮液; 从萃余水相中分离出乙二醇醚萃取相; 将乙二醇醚提取相加热至第二较高温度以形成包含含有一部分亲水性有机化合物和二醇醚萃余相的含水萃取相的悬浮液; 并从水相萃取相中分离出该二醇醚萃余相。 所选择的二醇醚在水中具有相反的溶解度,并且亲水性有机化合物的分配比值K大于0.1。 该方法可用于回收通过发酵生产或生产或用于各种制造工艺中的有价值的亲水性有机酸。
