    • A coupling for joining a pair of tubes having ends has a ball having a substantially spherical outer surface and a center and formed with an outwardly projecting pin extending along an axis radial of the ball and center. The pin is dimensioned to fit snugly into the end of one of the tubes. Another pin dimensioned to fit snugly into the end of the other of the tubes has a seat shaped to complementarily fit against the surface of the ball. The other pin is secured to the surface the ball at any of a multiplicity of angular offset positions thereon. A threaded bore is formed in the ball and centered on a bore axis traversing the center and another bore is formed in the other pin, opening into the seat, and centered on a bore axis extending at an acute angle to the respective pin. A screw extends through the bore of the other pin and is seated in the threaded bore of the ball. Normally the bore axis of the threaded bore extends at an acute angle to the axis of the pin of the ball.
    • 用于连接具有端部的一对管的联接器具有球,其具有基本上球形的外表面和中心,并且形成有沿着球和中心的径向轴线延伸的向外突出的销。 该销的尺寸适合紧贴在其中一个管的末端。 尺寸适合紧贴在另一个管的端部中的另一个销具有成形为与球的表面互补配合的座。 另一个销在其上的多个角度偏移位置中的任何一个上固定到表面。 螺纹孔形成在球中并且以穿过中心的孔轴为中心,另一个孔形成在另一个销中,开口到座中,并以与相应销相对应的锐角延伸的孔轴为中心。 螺钉延伸穿过另一个销的孔,并且位于球的螺纹孔中。 通常,螺纹孔的孔轴线与球的销的轴线成锐角。

    • An apparatus for grinding a point on a tip of an elongated tungsten-electrode rod has a base, a disk rotatable on the base about a disk axis and having a disk face substantially perpendicular to the disk axis, and a drive on the base for rotating the disk about the disk axis. An elongated holder extending along a holder axis is adapted to hold the rod to be ground with its tip projecting from a front end of the holder. This holder has a rear end formed with an outwardly open annular groove. A stationary tip support having a notch open toward the disk is adapted to cradle the tip of the rod immediately adjacent the disk and an outer holder support spaced from the tip support has a notch open parallel to the notch of the tip support and is adapted to cradle the holder at the groove thereof. An inner holder support engaging the holder presses the holder and tip into the notches of the tip support and outer support. These supports are aligned along a line extending skew to the disk face and axis.
    • 用于研磨细长钨电极棒的尖端上的点的装置具有基座,可在基座上围绕盘轴线旋转并具有基本上垂直于盘轴线的盘面的盘,以及用于旋转的基座上的驱动 磁盘绕磁盘轴。 沿着保持器轴线延伸的细长保持器适于保持待研磨的杆,其尖端从保持器的前端突出。 该支架具有形成有向外开口的环形槽的后端。 具有朝向盘开口的凹口的固定尖端支撑件适于支撑紧邻盘的杆的尖端,并且与尖端支撑件间隔开的外保持器支撑件具有平行于尖端支撑件的凹口开口的凹口,并且适于 将支架支撑在其凹槽处。 接合保持器的内部保持器支撑件将保持器和尖端压入尖端支撑件和外部支撑件的凹口中。 这些支撑沿着延伸到盘面和轴线的线对准。
