摘要： The present invention is directed to methods and apparatus for conducting gas chromatography more rapidly than previously disclosed. By means of the present invention the time necessary to conduct a gas chromatographic analysis can be reduced by more than 50%. The methods and apparatus employed reduce system dead volumes to prevent band broadening and mixing of the sample components as the gas sample is analyzed. The present invention also relates to the apparatus described above as applied to controlling chemical, refining, and other processes.

摘要： An edge finder held on the end of a spindle of a milling machine is provided with a flat on the outer cylindrical surface of the working end member thereof. When the edge of a work piece mounted on the table of the milling machine is slowly advanced by a machinist to contact the rotating end member, the flat thereon produces an audible clicking sound each revolution of the spindle. Moreover, upon contact, the flat on the rotating working end member causes it to vibrate radially thereby enhancing the sidewise jump thereof and making it easier for the jump to be observed by the machinist.
摘要翻译：保持在铣床的主轴端部的边缘检测器在其工作端构件的外圆柱形表面上设置有平面。当安装在铣床的工作台上的工件的边缘通过机械师缓慢前进以接触旋转端部构件时，其上的平面在主轴的每转一圈上产生可听到的咔嗒声。此外，接触时，旋转工作端部件上的扁平部使其能够径向地振动，从而增强其侧向跳动，并且使机器人更容易观察到跳跃。

摘要： A drive line disconnect mechanism for effecting rapid connection and disconnection of the drive line between a power module and the ground-engaging wheels of a work module, said modules being adapted to be joined together into an articulated modular vehicle. The drive line disconnect mechanism includes a first toothed coupling half mounted on a power module coupling member and a second toothed coupling half mounted on a work module coupling member wherein the second toothed coupling half is mounted so as to permit multi-planar pivotal movement relative to the first toothed coupling half. Centering means permit initial alignment and biasing means thereafter permit driving engagement.
