    • A polymer dispersion comprising an aqueous, continuous phase and dispersed particles of polyurethane, which is based on organic, non-aromatic isocyanates with a functionality of at least 2, said polyurethane having a high degree of crystallinity and whose crystalline phase has a melting point between 25 and 70° C., and a copolymer and/or terpolymer having a Tg (glass transition temperature) between −20 and +50° C. obtainable by emulsion polymerization of ethylenically unsaturated monomeric materials containing only C, H, O and/or N atoms, which monomeric materials comprise from 0.5 to 15 percent on the total of monomeric materials of monomers containing at least one nitrile group, in a weight ratio between 50:50 and 10:90 (polyurethane to emulsion polymer), in which the particles of the dispersion are in the form of multiphase particles comprising said polyurethane and said copolymer and/or terpolymer and which dispersion is obtainable by emulsion polymerization of the monomeric materials in the presence of the polyurethane dispersion, said eventual polymer dispersion having a solids content of 30 to 70%. The invention also comprises the use of these dispersions as an adhesive, especially for heat seal laminating, preferably for 3-D(imensional) Laminating. The dispersion is also useful as a size for glass fibers.
    • 一种包含水性连续相和分散的聚氨酯颗粒的聚合物分散体,其基于官能度至少为2的有机非芳族异氰酸酯,所述聚氨酯具有高结晶度,并且其结晶相的熔点在 25℃和70℃,以及具有-20℃至+ 50℃之间的Tg(玻璃化转变温度)的共聚物和/或三元共聚物可通过仅含烯属不饱和单体材料的乳液聚合得到 C,H,O和/或N原子,该单体材料占含有至少一个腈基的单体的单体材料的总量的0.5至15%,重量比为50:50至10:90(聚氨酯至 乳液聚合物),其中分散体的颗粒是包含所述聚氨酯和所述共聚物和/或三元共聚物的多相颗粒的形式,并且所述分散体可通过所述共聚物和/或三元共聚物的乳液聚合获得 在聚氨酯分散体存在下的聚氨酯材料,所述最终的聚合物分散体的固含量为30-70%。 本发明还包括使用这些分散体作为粘合剂,特别是用于热封层压,优选用于3-D(显像)层压。 该分散体也可用作玻璃纤维的尺寸。

    • A method is disclosed, for recognizing whether some electronic data is the digital representation of a piece of text and, if so, in which character encoding it has been encoded. A fingerprint is constructed from the data, wherein the fingerprint comprises, for each of a plurality of predetermined character encoding schemes, at least one confidence value, representing a confidence that the data was encoded using said character encoding scheme. The fingerprint also comprises a frequency value for each of a subset of byte values, each frequency value representing the frequency of occurrence of a respective byte value in the data. A statistical classification of the data is then performed based on the fingerprint.
    • 公开了一种用于识别一些电子数据是否是一段文本的数字表示的方法,并且如果是,则编码其中的字符编码。 从数据构建指纹,其中对于多个预定字符编码方案中的每一个,指纹包括至少一个置信度值,表示使用所述字符编码方案对数据进行编码的置信度。 指纹还包括字节值子集中的每一个的频率值,每个频率值表示数据中相应字节值出现的频率。 然后根据指纹进行数据的统计分类。
