    • In the preparation of dispersions of magnetic pigments in organic solvents, dispersants which have a sterically stabilizing effect are used. Milling results in division of the pigment aggregates, which combine again as a result of attractive forces to give secondary agglomerates in the event of poor stabilization. These flocculating materials must be removed from the dispersion by expensive filtration. If an increase in the fineness or pigment batch fluctuations lead to an increase in the secondary agglomerates, filter breakthroughs may occur, resulting in a dramatic reduction in the yield of magnetic recording medium. It was found that excellent dispersion stability is achieved when the magnetic pigments are first precoated with a long-chain dispersant. Subsequently, the use of charge-generating, low molecular weight codispersants, a charge build-up on the pigment is specifically induced by means of bases or acids. The electrostatic repulsion which additionally becomes effective leads to an increase in the dispersion stability. The charges on the pigment are monitored by means of ESA measurements (electrokinetic sound amplitude). These ESA measurements make it possible to establish the order of addition of the dispersants and the optimum amount of codispersant.
    • 在制备磁性颜料在有机溶剂中的分散体时,使用具有空间稳定作用的分散剂。 研磨会导致颜料聚集体的分离,其由于吸引力而再次结合,以在稳定性差的情况下产生二次聚集体。 这些絮凝材料必须通过昂贵的过滤从分散体中除去。 如果细度或颜料批量波动的增加导致二次附聚物的增加,则可能发生滤光器突破,导致磁记录介质的产率显着降低。 发现当首先用长链分散剂预涂磁性颜料时,可获得优异的分散稳定性。 随后,通过碱或酸特异性地诱导使用电荷产生的低分子量分散剂,颜料上的电荷积聚。 另外变得有效的静电排斥导致分散稳定性的增加。 通过ESA测量(电动声音振幅)监测颜料上的电荷。 这些ESA测量使得可以确定分散剂的添加顺序和最佳的分散剂量。

    • A broadcast message may be initiated or received at a peer node. The node obtains an uplink bandwidth available for broadcasting the message over the network and a number of copies that can be broadcast based on the available bandwidth. The node determines a range of key values for finger nodes that should receive copies of the broadcast message from a finger table. The finger table entries include references to finger nodes and key values associated with the finger nodes. The node determines which other nodes should receive copies of the broadcast message from range of key values and the number of copies. The node also determines an End ID for each recipient node. A copy of the broadcast message and corresponding End ID is sent to a finger node if the finger node's key value is within a range of key values specified by the End ID.
    • 可以在对等节点处发起或接收广播消息。 节点通过网络获得可用于广播消息的上行链路带宽,并且可以基于可用带宽广播多个副本。 节点确定应从手指表接收广播消息的副本的手指节点的键值范围。 手指表条目包括对手指节点的引用和与手指节点相关联的键值。 该节点确定哪些其他节点应该从键值范围和份数中接收广播消息的副本。 节点还确定每个收件人节点的结束ID。 如果手指节点的键值在结束ID指定的键值范围内,则将广播消息和对应的结束ID的副本发送到手指节点。
