    • The invention describes a cable with a recyclable covering, particularly for transporting or distributing medium and high voltage electricity, in which at least one covering layer is based on a thermoplastic polymer material comprising a propylene homopolymer or a copolymer of propylene with ethylene and/or another alpha -olefin other than propylene. The cable of the invention possesses superior mechanical and electrical properties and in particular allows the use of high operating temperatures, even higher than those of cables with coverings formed from crosslinked polymer base materials.
    • 本发明描述了一种具有可回收覆盖物的电缆,特别是用于输送或分配中等和高压电力的电缆,其中至少一个覆盖层基于包含丙烯均聚物或丙烯与乙烯和/或其它物质的共聚物的热塑性聚合物材料 丙烯以外的α-烯烃。 本发明的电缆具有优异的机械和电学性能,特别是允许使用高的操作温度,甚至高于由交联的聚合物基材形成的覆盖物的电缆。

    • Heat rolls and fuser belts utilized in the fusing step of the electrophotographic process are disclosed. These belts and rollers eliminate toner offset while still maintaining excellent release characteristics of the printed page from the fuser. The heat rolls comprise a core member having coated thereon a plurality of concentric layers, wherein at least one of said layers (preferably the top layer) does not contain electrically conductive materials and wherein the roll exhibits electrical breakdown at about 250 volts or less. The fuser belts comprise a heat resistant resin substrate (such as a polyimide belt) carrying thereon a plurality of layers coating the outer surface of said belt, wherein at least one of said layers (preferably the top layer) does not contain electrically conductive materials and wherein the belt exhibits electrical breakdown at about 250 volts or less.
    • 公开了在电子照相方法的定影步骤中使用的热辊和定影带。 这些皮带和滚筒可消除墨粉偏移,同时仍然保持打印页面从定影器获得良好的脱模特性。 热辊包括其上涂覆有多个同心层的芯构件,其中所述层(优选顶层)中的至少一个不包含导电材料,并且其中辊在约250伏特或更小的电压下显示电击穿。 定影带包括承载其上涂覆有所述带的外表面的多个层的耐热树脂基材(例如聚酰亚胺带),其中所述层(优选顶层)中的至少一个不含导电材料, 其中所述带在约250伏或更小的电压下展现电击穿。
