摘要： A pneumatic outlet gate of a railroad hopper car has an valve member mounted for rotation in a discharge tube between open and closed positions. The valve member is an arcuate segment terminating laterally at edge faces. The edge faces are angled such that in the upper half of the discharge tube they always slant downwardly from the surface of the tube, while in the lower half of the discharge tube the edge faces face downwardly. An arrangement of stops and abutments prevents rotation of the valve member to a location where the edge faces could trap lading against the discharge tube. Accordingly, the edge faces are self-emptying.

摘要翻译： 铁路料斗车的气动出口门具有安装成在打开和关闭位置之间在放电管中旋转的阀构件。 阀构件是在边缘侧面横向终止的弓形段。 边缘面是倾斜的，使得在放电管的上半部分中，它们总是从管的表面向下倾斜，而在放电管的下半部中，边缘面朝下。 止动件和支座的布置防止阀构件旋转到边缘可以将排水管锁定在放电管上的位置。 因此，边缘面是自排空的。

摘要： A gasket for railroad car manways or hatches is mounted on the top of a loading nozzle. The gasket is a ring having an inverted J-shaped cross section. It is held in position by a long down leg and a short leg. The legs are joined by a bail. The junction between the outside surfaces of the bail and down leg has a chamfer to avoid interference with a closed manway cover. Chevrons are formed on the upper surface of the bail. A flexible loop engages a bolt bracket on the loading nozzle to prevent dislodging of the gasket during opening of the cover.
