摘要： A back lighted trip indicator for a circuit breaker comprising an opaque tubular shield and a light translucent prism telescopically received in the shield and movable from a position totally within said shield when the manual operator is in the "ON" position to an exposed condition when the manual operator moves to the "OFF" position thereby to reflect ambient light through a frontal face on the prism to back light indicia on the frontal face of the prism.

摘要： An improved document feeder employs sets of rollers between which it feeds documents of different lengths to generate and maintain gaps of equal length between the documents while transporting them at a constant speed. A first group of rollers separate stacked documents and start the documents moving at a low speed along the track. A second group of rollers, operated at a higher speed, receive documents from the first group of rollers and increase the speed of the first document relative to a second document, still in contact with the first group of rollers, thereby providing an initial gap which continues to lengthen until the second document reaches the second group of rollers. A third group of rollers receives the documents after they leave the second group, imparting a constant system transport speed to them. The first and second groups of rollers are then able to further adjust the gap by changing the speed of a second document, and after the desired gap has been established, reverting to transport speed before transferring the second document to the third group of rollers.
摘要翻译： 改进的文件馈送器使用一组辊，在辊之间馈送不同长度的文档以在恒定速度下传送它们之间产生并保持文件之间长度相等的间隙。 第一组辊分离堆放的文件并开始沿着轨道以低速移动的文件。 以较高速度操作的第二组辊子从第一组辊子接收文件并且增加第一文件相对于仍与第一组辊子接触的第二文件的速度，从而提供初始间隙， 继续延长，直到第二个文件到达第二组辊子。 第三组辊子在离开第二组后接收文件，赋予它们恒定的系统运输速度。 然后，第一和第二组辊能够通过改变第二文件的速度来进一步调节间隙，并且在所需的间隙已经建立之后，在将第二文件转移到第三组辊之前还原到传送速度。
