    • Process for the preparation of dimeric fatty acid C1-4 alkyl esters comprising the steps of A) reacting a soybean oil condensate obtained from the deodorization of refined soybean oil and which contains less than 30% by weight of free and esterified oleic acid based on the total weight of free and esterified fatty acids in said condensate, with a C1-4 alkanol in the presence of a zinc oxide catalyst to convert free fatty acids and fatty acid glyceride esters to fatty acid C1-4 alkyl esters; B) removing excess C1-4 alkanol, volatile reaction by-products, water, and the zinc oxide catalyst from the resulting reaction mixture; C) heating the reaction mixture from step B) under vacuum to obtain a distillate of fatty acid C1-4 alkyl esters; D) separating the distillate from step C) into a fraction containing mostly C16-18 saturated fatty acid C1-4 alkyl esters and a second fraction containing mostly C16-18 unsaturated fatty acid C1-4 alkyl esters wherein the oleic acid C1-4 alkyl ester content is less than about 35% by weight thereof; and E) dimerizing said second fraction in the presence of montmorillonite clay.
    • 用于制备二聚脂肪酸C 1-4烷基酯的方法,包括以下步骤:A)将由精制大豆油除臭得到的大豆油缩合物与基于总计的含有少于30重量%的游离和酯化油酸反应 所述缩合物中游离和酯化的脂肪酸的重量与C1-4链烷醇在氧化锌催化剂存在下将游离脂肪酸和脂肪酸甘油酯转化为脂肪酸C 1-4烷基酯; B)除去过量的C 1 -C 4烷基酯, 4链烷醇,挥发性反应副产物,水和氧化锌催化剂; C)在真空下加热来自步骤B)的反应混合物,得到脂肪酸C 1-4烷基酯的馏出物; D)分离 来自步骤C)的馏出物成为主要含有C 16-18饱和脂肪酸C 1-4烷基酯的馏分和主要含有C 16-18不饱和脂肪酸C 1-4烷基酯的第二馏分,其中油酸C 1-4烷基酯含量 小于约35重量%; 和E)在蒙脱石粘土存在下使所述第二级分二聚。

    • A connector having two connector portions which are adjustably connected together to be in aligned relationship and with each portion receiving the respective ends of optical fibre lines to be connected together in abutting and aligned relationship. At least one connector portion has an inner collar in which the end of the fibre is disposed to lie in eccentric relationship to the longitudinal axis of the collar. This inner collar is rotatably disposed in a hole in an outer collar with the hole being eccentrically disposed with respect to the longitudinal axis of its outer collar. By angular adjustment of the inner and outer collars with respect to each other the respective ends of the optical fibre lines can be positioned with respect to each. At least one inner collar can be of transparent material so that optical leakage occurring at the connector can be easily detected.
    • 具有两个连接器部分的连接器,其可调节地连接在一起成对准关系,并且每个部分接收光纤线路的相应端部以相邻和对准的关系连接在一起。 至少一个连接器部分具有内部轴环,其中纤维的端部设置成与轴环的纵向轴线成偏心关系。 该内圈可旋转地设置在外圈中的孔中,孔相对于其外衣的纵向轴线偏心地设置。 通过相对于彼此角度地调节内圈和外圈,光纤线的相应端可以相对于每个定位。 至少一个内圈可以是透明材料,从而可以容易地检测出在连接器处发生的光学泄漏。
