    • Ethylene is polymerized using a Ziegler catalyst system consisting of (1) a titanium catalyst component and (2) an aluminum catalyst component, the component (1) used being the product (VI) which is obtained by a method in which (1.1) first (1.1.1) a carrier (I) and (1.1.2) a solution (II) of (IIa) a solvent, (IIb) a titanium trichloride and (IIc) magnesium chloride are combined with formation of a dispersion (III) and the latter is evaporated down with formation of an intermediate (IV), and (1.2) then (1.2.2) the intermediate (IV) obtained from (1.1), and (1.2.2) an aluminum component (V) consisting of (1.2.2.1) a complex of a certain oxacycloalkane and a certain aluminum compound and (1.2.2.2) if necessary, a certain free aluminum compound are combined, the resulting product (VI) being the catalyst component (1). In this process, a component (1) is employed which has been prepared using, in (1.1) under (1.1.2), a solution (II) which (i) contains a ketone as (IIa) and (ii) additionally contains (IId) a certain low molecular weight polymeric compound.
    • 使用由(1)钛催化剂组分和(2)铝催化剂组分组成的齐格勒催化剂体系聚合乙烯,所述组分(1)是通过以下方法获得的产物(VI):其中(1.1)第一 (1.1.1)将(IIa)溶剂(IIb),三氯化钛和(IIc)氯化镁的(IIa)溶液(II)和(1.1.2)与形成分散体(III) (1.2)然后(1.2.2)由(1.1)得到的中间体(Ⅳ)和(1.2.2)由(Ⅳ)组成的铝组分(Ⅴ)组成的铝组分(Ⅴ) (1.2.2.1)某种氧杂环烷烃和某种铝化合物的络合物和(1.2.2.2)(如果需要)合并一定的游离铝化合物,所得产物(VI)是催化剂组分(1)。 在该方法中,使用在(1.1)(1.1.2)中使用(1.1)中的(1.1)制备的组分(1),其中(i)包含酮作为(IIa)和(ii)另外含有 (IId)某种低分子量聚合物。

    • A spatially movable device 1 is disclosed which is provided with actuators 7a-7f in such a manner that the system consists of a manual unit 2 with a process control unit 5 and a input unit 6 as well as a monitor 8. The manual unit 2 is operated in such a manner that the control elements 3a-3f are controlled by an operator's hand which through individual fingers controls the selection of various position parameters. A slider 4 is provided which controls the direction and speed of the selected parameter change with the slider being accessible to the thumb of the operator in order to provide complete operation by one hand and simultaneously setting and controlling the parameter values which are displayed on the monitor 8.
