    • An abrasive tool (112) includes an assembly of tool precursors (116). At least one of the tool precursors has a continuous polycrystalline diamond, polycrystalline cubic boron nitride, or ceramic material cutting element (18) formed into a blade shape. The abrasive tool can additionally include a setting material (68), which is configured to attach the tool precursors and form a single mass. The selection, arrangement, and setting of the tool precursors can result in an abrasive tool having a predetermined cutting configuration. Methods for forming such an abrasive tool are also disclosed.
    • 研磨工具(112)包括工具前体(116)的组件。 至少一个刀具前体具有形成叶片形状的连续多晶金刚石,多晶立方氮化硼或陶瓷材料切削元件(18)。 研磨工具可另外包括设置材料(68),其被配置为附接工具前体并形成单个质量块。 工具前体的选择,布置和设置可以导致具有预定切割构造的研磨工具。 还公开了形成这种研磨工具的方法。

    • An air flow device (20) includes a flow passage (30) having opposite ends (34, 36). The flow passage (30) is divided into a plurality of sequential portions (42, 44, 46, 48) between the ends including an inlet portion (42) extending into the flow passage (30) from an inlet end (34) an outlet portion (48) disposed at the opposite end (36) of the flow passage (30) from the inlet portion (34), and at least one intermediate passage portion (44, 46) between the inlet passage portion and the outlet passage portion. Each of a plurality of divider sets (60) are positioned in a different sequential portion of the passage to divide that passage portion (64a, 64b, 64c, 64d) into a predetermined number of additional passages. At least one of the additional passages is smaller than at least one of the preceding passages.
    • 空气流动装置(20)包括具有相对端(34,36)的流动通道(30)。 流动通道(30)在端部之间分成多个顺序部分(42,44,46,48),包括从入口端(34)延伸到流动通道(30)中的入口部分(34),出口 从入口部分(34)设置在流动通道(30)的相对端(36)处的部分(48)和在入口通道部分和出口通道部分之间的至少一个中间通道部分(44,46)。 多个分割器组(60)中的每一个定位在通道的不同顺序部分中,以将该通道部分(64a,64b,64c,64d)分成预定数量的附加通道。 附加通道中的至少一个小于前述通道中的至少一个通道。
