    摘要： A process for the preparation of tripeptides of the general formula IU-A-B-C-OH Iin which U denotes hydrogen or a urethane protective group and A, B and C denote amino acids, by reaction of a compound of the general formula IIU'-B-OH IIin which U' is a urethane protective group which can be eliminated by hydrogenolysis, with a compound of the general formula IIIH-C-OR IIIin which R denotes alkyl, by the PPA method, elimination of U', and reacting the resulting compound of the formula IVH-B-C-OR IVwith a compound of the formula VU-A-OH Vin the presence of propylphosphonic anhydride, and finally eliminating R enzymatically.

    摘要： The compressor cascade comprises a plurality of tandem-connected membrane pumps, each of the pumps having a plurality of stroke chambers whose volumes decrease in the direction of the fluid flow through the pumps. Each chamber has several parallel-connected input/output channels for interconnecting the individual membrane pumps and a check valve in each input/output channel for forcing the fluid in a specified direction. By electrostatic attraction forces, the membranes in the pumps are energized synchronously to resonance oscillations of the same frequency and deflection, building up the necessary operating pressure as the fluid is moved from the stroke chamber of one membrane pump into the smaller volume stroke chamber of the next succeeding membrane pump. The movement of the fluid through the membrane pumps of the compressor cascade leads to its compression, and the pressure at the end of the cascade is related to the reduction in volume of each succeeding stroke chamber.

    摘要： In the conversion of trichloroethene and tetrachloroethene into dichloroacetyl chloride (DAC) or trichloroacetyl chloride (TAC) by means of oxygen, the reaction mixture is passed several times as a thin film through the reaction zone. The reaction time for achieving a certain conversion is in this way reduced.In the preparation of DAC, a constant content of acid chloride is established in the reaction mixture by removing some of the mixture and working this up by distillation, while the circulating reaction mixture is simultaneously topped up with fresh trichloroethene.In this way, side reactions are suppressed and the amount of by-products is reduced.

    摘要翻译： 在通过氧将三氯乙烯和四氯乙烯转化为二氯乙酰氯（DAC）或三氯乙酰氯（TAC）时，反应混合物通过反应区通过数倍的薄膜。 实现某种转换的反应时间以这种方式减少。 在DAC的制备中，通过除去一些混合物并通过蒸馏进行处理，在反应混合物中建立恒定含量的酰氯，同时循环反应混合物同时充满新鲜的三氯乙烯。 这样，副反应被抑制，副产物的量减少。

    摘要： A film supplying magazine which receives a pack of film sheets, covered with a light-tight sheathing and is insertable into a device which removes from said pack individual film sheets, comprises a box receiving a film pack, and a cover for closing the box. The sheathing has a winding flap while the magazine has an externally operated rotatable winding shaft to which the flap of the sheathing is connected so that the flap together with the sheathing is pulled off the pack and wound on the shaft when the latter is rotated. Velcro tapes are provided at the free end of the flap and at a portion of the winding shaft, which ensure an automatic connection between the flap and the shaft.
