摘要： An elastic knee joint bandage is in tubular form with an elastic profile insert encircling the knee cap in an opening. The areas of the profile insert adjacent to the poles of the knee cap are connected by a flexible, unstretchable tension member placed around the knee cap in a curve in the profile insert on the side of the fibula, so that when the distance between these areas is increased by flexing the knee joint, the distance of the curve from the line joining the poles of the knee cap is reduced, and the edge of the opening of the profiled insert in question on the adjacent side of the knee cap presses it medially with a shifting and centering effect.

摘要： An improved process for preparing cyclic acetals of 3-formyl-2-butenyltriphenylphosphonium chloride by acetalization of 3-formyl-2-butenyl acetate with an aliphatic 1,3-diol, conversion of the resulting 4-acetoxy acetal into the corresponding 4-hydroxy acetal, Vilsmeier chlorination to give the corresponding 4-chloro acetal and subsequent reaction with triphenylphosphine entails carrying out the first 3 steps in an aliphatic or cycloaliphatic hydrocarbon or mixture of hydrocarbons with 6-8 carbons and the reaction with triphenylphosphine in an alkanol with 1-3 carbons and/or in aliphatic or cycloaliphatic hydrocarbon with 6-8 carbons or a corresponding mixture of hydrocarbons. The process is particularly advantageous when conversion of the 4-acetoxy acetal into the 4-hydroxy acetal is carried out with an aqueous alkali metal hydroxide solution in the presence of phase-transfer catalysts, and the first three, or all four, reaction stages are carried out in the same C.sub.6 -C.sub.8 -hydrocarbon.
摘要翻译：通过用脂肪族1,3-二醇缩醛化3-甲酰基-2-丁烯基乙酸酯与3-甲酰基-2-丁烯基三苯基氯化鏻的环状缩醛的改进方法，将得到的4-乙酰氧基缩醛转化为相应的4-羟基缩醛，Vilsmeier氯化，得到相应的4-氯缩醛，随后与三苯基膦反应需要在脂族或脂环族烃或碳原子数为6〜8的混合物中进行前3个步骤，并与三苯基膦在链烷醇中与1- 3个碳原子和/或具有6-8个碳原子的脂族或脂环族烃或相应的烃混合物。当在相转移催化剂存在下，用碱金属氢氧化物水溶液进行4-乙酰氧基缩醛转化为4-羟基缩醛时，该方法是特别有利的，而前三个或所有四个反应阶段是在相同的C6-C8-烃中进行。

摘要： A diaphragm drive apparatus for an objective lens with a manually preselectable diaphragm. The diaphragm drive apparatus is provided within the objective housing and is actuable by the shutter release mechanism of the camera to which it is affixed. The apparatus includes a plunger which operates a release mechanism. This release mechanism operates a drive lever which effects a connection with a diaphragm blade drive ring. A cam follower provided on an arm of the drive lever follows a cam surface on the release mechanism. The cam surface has one portion for effecting movement of the cam follower in engagement with the cam surface and a second portion which does not impart movement to the cam follower. On operation of the release plunger by the release system in the camera, the initial movement of the release mechanism on the drive lever effects closure of the diaphragm to its manually preselected position selected on the diaphragm setting ring and on subsequent movement permits release of the camera shutter mechanism without further movement of the diaphragm.
摘要翻译：一种具有手动预选膜片的物镜的光圈驱动装置。隔膜驱动装置设置在物镜壳体内并且可由其所固定的相机的快门释放机构致动。该装置包括操作释放机构的柱塞。该释放机构操作驱动杆，其实现与隔膜叶片驱动环的连接。设置在驱动杆的臂上的凸轮从动件跟随释放机构上的凸轮表面。凸轮表面具有用于实现凸轮从动件与凸轮表面接合的运动的一个部分和不给凸轮从动件赋予运动的第二部分。在相机中通过释放系统操作释放柱塞时，释放机构在驱动杆上的初始移动可以使膜片关闭到在隔膜设置环上选择的手动预选位置，并且随后的移动允许相机的释放快门机构，无需膜片的进一步移动。
