    • A door seal for an inside compartment of a railway passenger vehicle. A door that moves on rollers laterally into and from a door opening to a stored position in a hollow portion of an adjacent wall. The lower portion of the door is located adjacent a threshold having a movable, flexible seal that moves between a flat position covering a roller track portion of the threshold to a substantially upright position against the bottom of the door when the door is located in a closed position. The seal is constructed of a resilient material and bends to be urged against the lower portion of the door in such a fashion as to seal out noise, debris, light and the like. When the door is open the seal returns to a flat, horizontal position to prevent an accumulation of debris or dirt in the door track which would interfere with movement of the door.
    • 铁路客运车内箱门密封件。 在辊子上横向移动到门开口到相邻壁的中空部分中的存储位置的门。 门的下部位于邻近具有可移动的柔性密封件的阈值处,当可移动的柔性密封件位于闭合位置时,该密封件在覆盖门槛的辊道部分的平坦位置与抵靠门的底部之间基本上直立的位置移动 位置。 密封件由弹性材料构成,并弯曲成以将密封噪声,碎屑,光等的方式推向门的下部。 当门打开时,密封件返回到平坦的水平位置,以防止门轨中的碎屑或污垢积聚,这将干扰门的移动。

    • A rail vehicle is disclosed for use on an elevated electric rail system having a lower rail below the vehicle and an upper rail above the vehicle. The vehicle includes a pair of lower wheels having independently rotatable flanges rollably carrying a vehicle cab along the lower rail and an upper wheel having independently rotatable flanges rollably engaging the upper rail. Electric motors, energized through contacts carried on the vehicle by an electric circuit associated with the upper rail, are drivingly connected through drive belts to the respective lower wheel to propel the vehicle along the rail system. The vehicle also includes a clamping rail brake carried by a vehicle which is engagable on the lower rail, and a vertically and laterally extendable servo system secured to the vehicle and carrying the upper wheel.
    • 公开了一种在具有在车辆下方的下轨道和在车辆上方的上轨道的高架电气轨道系统上使用的轨道车辆。 车辆包括一对下轮,其具有可沿着下轨道可滚动地承载车辆驾驶室的独立可旋转的凸缘,以及具有可独立旋转的凸缘,其可滚动地接合上轨道。 通过与上轨道相关联的电路承载在车辆上的触点通电的电动机通过驱动皮带驱动地连接到相应的下轮,以沿着轨道系统推进车辆。 车辆还包括由车辆承载的夹紧轨道制动器,其可接合在下轨道上,以及固定到车辆并承载上轮的垂直和横向延伸的伺服系统。

    • A front gun sight for use in combination with a conventional rear sight, including a front extended tapered sighting surface, having a center portion of a contrasting color to the side portions, allowing a quick and accurate aiming of the gun even under poor light conditions. The tapered sighting surface is secured to a tapered mount which itself may be attached on a gun barrel over an existing sight. The extended tapered sighting surface forms a linear sighting line allowing the rear sigt to be lined up with the top front of the tapered sighting surface to align the projectile path with the target.
    • 与常规后视镜组合使用的前枪瞄准镜,包括前延伸的锥形瞄准表面,其具有与侧部对比的中心部分,允许即使在较差光线条件下也能快速准确地瞄准枪。 锥形瞄准表面固定到锥形安装座,其本身可以在现有视线上附接在枪管上。 延伸的锥形瞄准表面形成线性瞄准线,允许后视镜与锥形瞄准表面的顶部前部对齐,以将射出轨道与目标对准。
