摘要： A current-limiting contact arrangement includes a conductor rail including a stationary contact and including two current loops extending at opposite sides of the conductor rail in respective planes parallel to a center plane of the contact arrangement. A contact arm including a movable contact which can be brought into and out of contact with the stationary contact is provided, the current loops extending in respective planes parallel to a center plane of the contact arrangement and along an entire opening travel of the movable contact. An arc control device including arc splitters and a cassette including a first part and a second part and an insulating material are also provided. The arc splitters are disposed in a positive-locking manner in an interior of the cassette, the contact arm and a part of the conductor rail including the stationary contact extending into the interior of the cassette, and the current loops being disposed in a positive-locking manner at outer walls of the cassette. An assembly of the cassette, the arc splitters and the conductor rail is received in a positive-locking manner by inner surfaces of a switching device enclosure.

摘要： A description is given of a process for the industrial preparation of methylhydroxyalkylcelluloses (MHACs) by reaction of cellulose with alkali metal hydroxide and subsequent reaction with an alkyl halide and hydroxyalkylating agent, characterized in that the reaction is carried out batchwise in a reactor which has an L/D ratio of less than 2.5 and in which the unmixed regions are minimized and the batch reactor is preceded at the inlet by a continuously operated cellulose milling facility and is followed at the outlet by a continuously running plant for milling and drying the products, with the product being transported by action of gravity. An apparatus for carrying out this process and the methylhydroxyalkylcellulose obtainable by the process are also described.
摘要翻译：给出了通过纤维素与碱金属氢氧化物的反应和随后与烷基卤化物和羟烷基化剂的反应来工业制备甲基羟基烷基纤维素（MHAC）的方法的描述，其特征在于反应在具有 L / D比小于2.5，其中未混合区域最小化，并且间歇反应器在入口之前通过连续操作的纤维素研磨设备，并且在出口处通过连续运行的设备进行研磨和干燥，产品通过重力作用运输。还描述了用于进行该方法的设备和通过该方法可获得的甲基羟烷基纤维素。
