    摘要： A method for preparing human and other animal unbilical cords for use as a vascular replacement and/or arterial venous fistula which permits the umbilical cord which is to be grafted to be preformed into a desired predetermined configuration. The method includes the steps of initially flushing the cord in an aqueous solution, and then mounting the flushed cord upon a mandrel having the desired configuration. The mounted cord is immersed in ethyl alcohol until substantially dehydrated and preformed, and is thereafter immersed for fixation in an aldehyde selected from the class consisting of dialdehyde starch and gluteraldehyde, with the aldehyde immersion fixing the tissue into a shape conforming to the mandrel upon which it is mounted.

    摘要： In the tanning or re-tanning of a hide with a tanning composition comprising a tanning-active substance and at least one of a Cr(III) salt, a dicarboxylic acid, a dicarboxylic acid salt, an emulsifier and an acid-binding agent, the improvement which comprises employing as said tanning-active substance a carboxylic acid carrying at least one of an ester, urethane or amide group. Advantageously the agent has at least two carboxyl groups per molecule and a molecular weight of about 170 to 30,000, preferably 310 to 10,000. The products are softer and better through-tanned and there is maximum utilization of chromium, thereby minimizing the waste disposal problem.

    摘要： A new tanning agent is provided comprising an organic salt of a phosphorated and ethoxylated saturated fatty acid. The tanning agent is prepared by reacting a saturated fatty acid having 12 to 20 carbon atoms with ethylene oxide, posphorating the resulting ethoxylated fatty acid ester with posphoric anhydride, and neutralizing the phosphorated ester with a strong organic base, such as triethanolamine. The tanning agent is preferably dissolved in a water soluble solvent such as dimethyl formamide and may be diluted with water for addition in the wet processing of leather. The new tanning agent may be added to the leather in the tanning wheel either during the initial tanning or during retanning, and is particularly useful in connection with chrome tanned leathers. Such tanning agents increase dye values and improve softness and other properties of the leather. They also permit the reduction or elimination of chrome tanning agents and fat liquors in the retanning stage as well as improving take up of chrome in the tanning and/or retanning.

    摘要翻译： 提供了包含磷酸化和乙氧基化饱和脂肪酸的有机盐的新的鞣剂。 通过使具有12至20个碳原子的饱和脂肪酸与环氧乙烷反应制备鞣剂，使得到的乙氧基化脂肪酸酯与磷酸酐沉淀，并用强有机碱例如三乙醇胺中和磷酸酯。 鞣剂优选溶解于水溶性溶剂如二甲基甲酰胺中，并可用水稀释以在皮革的湿法加工中加入。 新鞣制剂可以在初始鞣制期间或在复鞣期间加入到鞣制车轮中的皮革中，并且与铬鞣皮革相关是特别有用的。 这种鞣剂增加了染料的值，改善了皮革的柔软性和其它性能。 它们还允许在复鞣阶段减少或消除铬鞣剂和脂肪液，以及改善鞣制和/或复鞣中铬的吸收。
