摘要： The novel urethanes correspond to the formula I below ##STR1## in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water.The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.
摘要翻译：新型氨基甲酸酯对应于下面的式I，其中a表示5至17的数，b表示1至7的数。这些氨基甲酸酯通过相应的全氟烷基乙醇/表氯醇加合物与甲苯二异氰酸酯反应制备。新型水性分散体基本上由新型氨基甲酸酯，阳离子或甜菜碱乳化剂和非离子乳化剂，水不溶性羧酸和/或二羧酸酯和烷二醇或聚烷二醇组成，其可以在水中在一侧或两侧进行醚化。新型氨基甲酸酯和新型水性分散体用于对纺织品，皮革和毛皮赋予疏油和疏水整理剂。它们也适用于未涂漆的木材的处理，例如未上漆的家具。

摘要： A method of producing sectional strips and sectional sheets of different thicknesses over the width, in which at least two metal strips or metal sheets of different widths are joined to each other by roll bonded cladding which thins the thickness of the overlaid strips. One strip is wider than the other strip which is narrower. The two strips are arranged symmetrically to the rolling direction center line. The facing surfaces of the two overlaid strips may be prepared for bonding them. The invention also concerns sectional strips or sectional sheets produced by the method.
摘要翻译：一种在宽度上制造不同厚度的分段条和截面片的方法，其中至少两个不同宽度的金属条或金属片通过辊压粘合的包层彼此接合，这使得覆盖条的厚度变薄。一条宽于另一条较窄的条。两条条对称地设置在轧制方向中心线上。两个重叠的条带的相对表面可以被制备用于粘合它们。本发明还涉及通过该方法制造的截面条或截面片。

摘要： Use of a resin mixture of, or of a mixed resin from, a melamine-formaldehyde resin and an anionically modified melamine-formaldehyde resin for tanning leather. The anionic modification of the melamine-formaldehyde resin is obtained by preparing the resin in the presence of alkali metal sulfite, alkali metal hydrogensulfite or alkali metal sulfamate. By partial modification it is possible to obtain a mixed resin, while mixing a modified with an unmodified resin gives a resin mixture.
摘要翻译：使用来自三聚氰胺 - 甲醛树脂和阴离子改性的三聚氰胺 - 甲醛树脂的树脂混合物或混合树脂用于鞣皮革。三聚氰胺 - 甲醛树脂的阴离子改性通过在碱金属亚硫酸盐，碱金属亚硫酸氢盐或碱金属氨基磺酸盐的存在下制备树脂而获得。通过部分改性，可以获得混合树脂，同时用未改性树脂混合改性树脂混合物。

摘要： Economy chrome tanning process wherein the pelts are pretreated before the tanning with 0.1 to 2% of an aldehyde- or keto-acid, preferably with glyoxylic acid or pyruvic acid, and are then tanned by customary methods. In this pretreatment, which is preferably carried out in the pickle, the tanning requires a chromium supply of only 1.25 to 1.5% of Cr.sub.2 O.sub.3 on weight of pelt. Despite this reduced amount of chrome tannin the results obtained are boil-resistant leathers with uniform chromium distribution, excellent color levelness and very good physical properties.
摘要翻译：经济铬鞣制方法，其中皮革在鞣制前用0.1至2％的醛 - 或酮酸，优选用乙醛酸或丙酮酸进行预处理，然后通过常规方法进行鞣制。在这种优选在酸洗中进行的预处理中，鞣制需要铬含量仅为皮质重量的1.25至1.5％的Cr 2 O 3。尽管铬单宁的量减少，但是获得的结果是具有均匀的铬分布，优异的颜色水平和非常好的物理性能的耐沸皮革。
