    • A method for transferring a data record from a first computer node (CN1) to a second computer node (CN3), as well as transmission-side and receiving-side computer nodes (CN1, CN3) and communications applications (CA1, CA3) to put the method into practice. The data record to be transferred is transmitted to a communications application (CA1) of the first computer node (CN1). This communications application (CA1) identifies the type of data record and transmits the data record, using different modes depending on the type of data record identified, to a communications application (CA3) of the second computer node (CN3), which then delivers the data record to the second computer node (CN3). The communications application (CA1) establishes a point-to-point broadband connection between the first computer node (CN1) and the second computer node (CN3) for the data record, and transmits the data record via this broadband connection if a data record of the first type is identified. If a data record of the second type is identified, the communications application (CA1) transmits the data in a connectionless fashion via an internet (KN1). The communications application (CA3) of the second computer node (CN3) receives a data record to be delivered in a different way, depending on the type of data record, and for the delivery, switches transparently between the different methods of receipt.
    • 一种用于将数据记录从第一计算机节点(CN1)传送到第二计算机节点(CN3)以及传输侧和接收侧计算机节点(CN1,CN3)和通信应用(CA1,CA3)的方法, 把方法付诸实践。 要传送的数据记录被发送到第一计算机节点(CN1)的通信应用(CA1)。 该通信应用(CA1)识别数据记录的类型,并且根据所识别的数据记录的类型使用不同的模式将数据记录发送到第二计算机节点(CN3)的通信应用(CA3) 数据记录到第二个计算机节点(CN3)。 通信应用(CA1)在用于数据记录的第一计算机节点(CN1)和第二计算机节点(CN3)之间建立点对点宽带连接,并且如果数据记录的数据记录 第一种类型被识别。 如果识别出第二类型的数据记录,则通信应用(CA1)通过互联网(KN1)以无连接的方式发送数据。 第二计算机节点(CN3)的通信应用(CA3)根据数据记录的类型以不同的方式接收要传送的数据记录,并且对于传送,在不同的接收方法之间透明地切换。

    • Manufacture of polymers of .alpha.-monoolefins by polymerization with a Ziegler catalyst system comprising (1) a catalyst component containing titanium and/or vanadium and (2) a particular compound of the metals aluminum, magnesium or zinc. The characteristic feature of the process according to the invention is that the catalyst component (1) containing titanium and/or vanadium is the solid-phase product (VII) contained by first (1.1) bringing a finely divided porous inorganic oxidic material (I), which has the formula Al.sub.2 O.sub.3 or SiO.sub.2.aAl.sub.2 O.sub.3, where a is a number from 0 to 2, into contact with an aluminum compound (II) dissolved in an organic solvent, to form a solid-phase product (III), then (1.2) bringing the solid-phase product (III) obtained in stage (1.1) into contact with a magnesium compound (IV), dissolved in an organic solvent, to form a solid-phase product (V), and finally (1.3) bringing the solid-phase product (V) obtained in stage (1.2) into contact with a compound (VI) of the transition metals titanium and/or vanadium to form a solid-phase product (VII).

    • A process for the manufacture of olefin polymers by polymerizing .alpha.-monoolefins of 2 to 8 carbon atoms by means of a catalyst which is obtained from a silicon-containing material (component a), an organo-metallic compound containing alkyl groups (component b) and a chromium compound (component c), wherein the catalyst employed is obtained by (1) first bringing into contact (1.1) an alkogel (component a) of the empirical formula SiO.sub.2 .multidot. m Al.sub.2 O.sub.3 .multidot. n ROH, where m is a number from 0 to 2, n is a number such that the content of ROH in the alkogel is from 1 to 85 per cent by weight and R is alkyl of 3 to 8 carbon atoms, and (1.2) an aluminum compound containing certain alkyl groups (component b), with intimate mixing, to form a solid-phase reaction product, (2) then bringing into contact (2.1) the solid-phase reaction product obtained from stage (1) and (2.2) a solution of a particular chromium compound (component c), with intimate mixing and evaporation of the solvent, and (3) finally heating the product, obtained from stage (2), in an anhydrous stream of gas containing oxygen, with the proviso that the product obtained from stage (1) or from stage (2) is dried and comminuted before it is used further in the next stage. This process makes it possible to influence the essential properties of the polymers in relatively diverse ways, in the desired direction, by relatively slight modifications of the catalyst.
