    • The present invention comprises a process for the production of flame-resistant polyesters with at least 50 mol-% ethylene carboxylate units through esterification or ester interchange and co-polycondensation of at least one diol and a dicarboxylic acid or its dialkyl ester with a carboxyphosphinic acid, whereby the carboxyphosphinic acid, before being added to the co-polycondensation mixture, is dissolved in ethylene glycol of not more than 90.degree. C., and the acid number of this solution is standardized to 50 to 350 mg KOH/g of carboxyphosphinic acid by adding at least one basic alkali metal compound in the absence of oxygen, and said solution is added to the co-polycondensation mixture during the second half of the esterification or ester interchange reaction.

    • A process for the production of cellulose carbamate from cellulose and urea through the conversion of the cellulose with excess urea in an inert liquid organic reaction carrier at a temperature in the range of 130 .degree. to 160.degree. C., separation of the reaction carrier from the reaction mixture and washing of the reaction mixture with water. The cellulose is intimately mixed with an aqueous urea solution. Then the water in the solution is replaced with the organic reaction carrier, and the reaction of urea and cellulose is carried out in the presence of an inert gaseous carrier to remove the by-product ammonia. Thereafter, the organic reaction carrier remaining in the reaction product is replaced with an aqueous urea solution and the resulting suspension of cellulose carbamate in the urea solution is filtered and washed free of urea with water. No liquid ammonia is required in this process.
    • 在惰性液体有机反应载体中,在130〜160℃的温度范围内,通过纤维素与过量尿素的转化,从纤维素和尿素生产纤维素氨基甲酸酯的方法,将反应载体与 反应混合物并用水洗涤反应混合物。 纤维素与尿素水溶液紧密混合。 然后用有机反应载体代替溶液中的水,尿素和纤维素的反应在惰性气态载体的存在下进行以除去副产物氨。 此后,将残留在反应产物中的有机反应载体用尿素水溶液代替,将所得到的尿素溶液中的氨基甲酸纤维素悬浮液过滤并用水洗涤尿素。 在这个过程中不需要液氨。

    • A substrate to be patterned, such as a textile web, is moved past an array of nozzles with discharge orifices closely spaced from its surface, the substrate being firmly backed at locations confronting the nozzles by being drawn against a supporting conveyor or by being led around rollers. The nozzles are electromagnetically operated by needle valves, the valve needles being carried by membranes under substantially balanced pressures from the printing liquor and from a fluid such as compressed air. The electromagnetic coils are energized by a generator of short current pulses separated by a low holding current, the generator including two complementary power transistors in series with a coil winding. A dyestuff applicator carrying one or more of such nozzles may be transversely displaceable across the substrate, under the control of a programmer, between intermittent advances of the substrate in its longitudinal direction.

    • A two-stage process for making a linear condensate of phenol and formaldehyde which can be extruded as a film or thread. In the first stage phenol and formaldehyde are reacted at about 90.degree. C to produce a clear low-viscosity phenol-methylol liquid, the pH of which is adjusted to a value greater than 3, say between 3.5 and 7. In the second stage the product of the first stage is added in aliquot portions to molten phenol having a pH of 3 or less, while maintaining the temperature at about 100.degree. C. After all the phenol-methylol has been added the mixture is slowly heated as the viscosity increases up to about 150.degree. C until there is no further increase in viscosity. The highly viscous end product can be extruded as a film or thread.
    • 用于制造苯酚和甲醛的线性缩合物的两阶段方法,其可以挤出为膜或线。 在第一阶段中,苯酚和甲醛在约90℃下反应以产生澄清的低粘度苯酚 - 羟甲基液体,其pH值调节至大于3,例如3.5-7之间。在第二阶段, 将第一阶段的产物以等份部分加入到pH为3或更低的熔融酚中,同时保持温度在约100℃。加入所有的酚 - 羟甲基后,随着粘度增加,将混合物缓慢加热 至约150℃,直到粘度没有进一步增加。 高粘度的最终产品可以挤出成膜或线。
