    • In an assembly made up of a spindle formed integrally with a revolving cutting element, the longitudinal axis of the spindle being the axis of rotation of the cutting element, the spindle is set into a cylindrical bearing. The bearing is fixed in the main body of the bit. The bearing element and a plate form a thrust surface with the end of the bearing at right angles to the axis of rotation of the spindle, which the other end of the bearing element made with the flange projecting outwards is held in the cutting element by means of the retaining ring which is fixed in the cutting element. A thrust surface at right angles to the axis of the rotation of the spindle is created between the top end of the bearing element and the cutting element and another between the retaining ring and the main body of the bit. By maintaining the spindle centrally in the bearing the wear on the bearing is radically reduced.
    • 在由与旋转切割元件整体形成的心轴组成的组件中,心轴的纵向轴线是切割元件的旋转轴线,心轴被设置成圆柱形轴承。 轴承固定在钻头的主体上。 轴承元件和板形成推力表面,轴承的端部与心轴的旋转轴线成直角,轴承元件的另一端由向外突出的凸缘制成,通过装置保持在切割元件中 固定在切割元件中的固定环。 在轴承元件的顶端和切割元件之间产生与心轴的旋转轴线成直角的止推表面,并且在保持环和钻头主体之间产生推力表面。 通过将主轴保持在轴承中心,轴承上的磨损被大幅降低。

    • This invention relates to a process for synthesizing para-diisopropylbenzene utilizing only cumene and propylene as raw materials. This synthesis technique offers the advantage of eliminating benzene as a raw material used in the process. The elimination of benzene is beneficial because it simplifies the process and eliminates the need to purchase and store benzene for use in the synthesis. The elimination of benzene from the synthesis is of particular value since the use of benzene in industrial applications has been under attack on the basis of environmental, safety, and health concerns. The present invention discloses a process for producing para-diisopropylbenzene from cumene and propylene, said process comprising the steps of (1) introducing a feed stream into an alkylation zone wherein said feed stream is comprised of cumene and propylene, and wherein said alkylation zone contains an alkylation catalyst; (2) allowing the cumene and propylene in the feed stream to react together to produce a first mixture of para-diisopropylbenzene and meta-diisopropylbenzene; (3) fractionally distilling the mixture of para-diisopropylbenzene and meta-diisopropylbenzene in a fractional distillation step to separate the meta-diisopropylbenzene from the para-diisopropylbenzene; (4) isomerizing the meta-diisopropylbenzene in the presence of a transalkylation catalyst to produce a second mixture of para-diisopropylbenzene and meta-diisopropylbenzene; (5) recycling the second mixture of para-diisopropylbenzene and meta-diisopropylbenzene recovered from the transalkylation step to the fractional distillation step; and (6) recovering the para-diisopropylbenzene that was separated from the meta-diisopropylbenzene by the fractional distillation step.
    • 本发明涉及以异丙基苯和丙烯为原料合成对二异丙基苯的方法。 该合成技术具有消除苯作为该方法中使用的原料的优点。 消除苯是有益的,因为它简化了过程,并且消除了购买和存储用于合成的苯的需要。 从合成中消除苯是特别有价值的,因为在工业应用中使用苯已经在环境,安全和健康问题的基础上受到攻击。 本发明公开了一种从枯烯和丙烯生产对二异丙基苯的方法,所述方法包括以下步骤:(1)将进料流引入烷基化区,其中所述进料流由枯烯和丙烯组成,其中所述烷基化区含有 烷基化催化剂; (2)使进料流中的枯烯和丙烯一起反应以产生对二异丙基苯和间二异丙基苯的第一混合物; (3)在分馏步骤中分馏蒸馏出对二异丙基苯和间二异丙基苯的混合物,以将间二异丙基苯与对二异丙基苯分离; (4)在烷基转移催化剂的存在下异构化间二异丙基苯以产生对二异丙基苯和间二异丙基苯的第二混合物; (5)将从烷基转移步骤回收的对二异丙基苯和间二异丙基苯的第二混合物循环到分馏步骤; 和(6)通过分馏步骤回收通过间二异丙基苯分离的对二异丙基苯。

    • A package is provided which is formed of a plastic film such as polyethylene or polypropylene. The package is formed to define an internal chamber to accommodate an article to be packed. A slit is provided in the wall and a hanger is provided a part of which extends through the slit. This part is provided with projections which lock the hanger against retraction into the internal chamber. The projections are rounded and/or wedge shaped to facilitate penetration of the hanger through the slit. According to the method by which such a package is formed the projections are shaped to penetrate through the slightly smaller slit without exceeding the elastic limit of the material from which the package is formed. Thereby the material can resume its original shape after the projections have been forced through the slit.
    • 提供由塑料膜如聚乙烯或聚丙烯形成的包装。 该包装形成为限定一个内部室以容纳要包装的物品。 在壁中设置狭缝,并且设置有一部分延伸穿过狭缝的衣架。 该部件设置有突出部,其将衣架锁定以防止收缩到内部腔室中。 突起是圆形和/或楔形的,以便于衣架穿过狭缝的穿透。 根据形成这种封装的方法,突起成形为穿过稍微较小的狭缝而不超过形成封装的材料的弹性极限。 因此,在突出部被迫穿过狭缝之后,材料可以恢复其原始形状。
