    • A firearms sight alignment system is provided which allows for the use of a collimated beam light source attached to a housing which binds the light beam with the direction of a firearm barrel. This light source thus provides a point at which to adjust the sighting apparatus of the firearm while the light source is shining upon an object some distance in front of the firearm barrel. The light source is aligned by a simple housing mechanism mounted to either a mandrel which is inserted into the bore of the firearm barrel or from a bracket attaching the light source to the barrel and alignment therewith.
    • 提供了一种枪支瞄准器对准系统,其允许使用附接到壳体的准直束束光源,该壳体将光束与枪支枪的方向结合。 因此,该光源提供了在光源照射在枪械枪前面一定距离的物体上时调整枪支瞄准装置的点。 光源通过安装到插入枪械枪管的孔中的心轴或从将光源附接到枪管并将其对准的支架的简单外壳机构对准。

    • A dipstick is suspended from a pivoting mount in the center of a cap. When performing a fluid level check, this cap is loosened from a wiper plug, which remains stationary in its tube housing as the dipstick is withdrawn through it. A series of internal wipers clean the dipstick as it passes through the wiper plug. Wiped fluids return to the fluid reservoir via undercuts in the individual wiper blades. The clean dipstick is then reinserted into the wiper plug to full depth, and the cap retightened on the wiper plug. The cap, dipstick, and wiper plug are then withdrawn together by pulling upwards from their tube housing. The actual fluid level in the reservoir will now show on the dipstick.
    • 量油尺从帽的中心的枢轴安装座悬挂下来。 当执行液位检查时,该盖帽从刮水器塞松开,当雨量计从其中取出时,雨刷保持固定在其管壳中。 一系列内部擦拭器在通过雨刷插头时清洁量油尺。 擦拭液体通过各个刮水片中的底切部分返回流体储存器。 然后将干净的量油尺重新插入雨刮器全深处,盖子将重新拧在雨刷上。 然后通过从其管壳向上拉动将帽,量油尺和雨刷插头一起拉出。 储存器中的实际液位现在将显示在量油尺上。
