摘要： In a speed control system for a carriage movable along a predetermined path, light beams originating at the ends of the path are deflected by light conductors aboard the carriage so that they are interrupted, as the carriage moves, by a slotted plate extending along the path. The light beams are then deflected by light conductors so that they are directed along the carriage path to light receivers situated at the ends of the path. Electrical pulses from the light receivers are ORed together and converted by a transducer to a signal representative of the actual carriage speed, and by a counter to a signal representative of the carriage position. The carriage position signal is converted, in accordance with a predetermined functional relationship, to a speed set signal which is compared with the actual carriage speed. A signal, representative of the difference between the actual speed and the set speed is used to control the driving motor for the carriage. The speed and position determination achieved by the control system makes it possible to stop the carriage at a predetermined fixed position regardless of the speed of the carriage by initiating braking at different carriage positions, depending on carriage speed.
摘要翻译：在用于沿着预定路径移动的支架的速度控制系统中，源于路径端部的光束被滑架上的光导体偏转，使得它们随着滑架移动而被沿着路径延伸的开槽板中断。然后光束被光导体偏转，使得它们沿着滑架路径被引导到位于路径端部处的光接收器。来自光接收器的电脉冲被或并置在一起，并由换能器转换成代表实际运载速度的信号，并且与代表托架位置的信号相反。滑架位置信号根据预定的功能关系被转换成与实际的车速进行比较的速度设定信号。用于表示实际速度和设定速度之差的信号用于控制用于滑架的驱动电动机。通过控制系统实现的速度和位置确定使得可以根据托架速度在不同的托架位置启动制动而将托架停止在预定的固定位置，而不管托架的速度如何。

摘要： An article storage rack apparatus for storing and dispensing articles in first-in, first-out order comprises side-by-side columns of slant racks, in which alternate slant racks in each column are inclined downwardly in opposite direction. Articles are introduced onto the topmost slant rack and slide downward by gravity to successively lower slant racks. The articles are transferred from a slant rack to the next lower slant rack by a transfer mechanism comprising tables which are movable vertically and tiltable. The articles are maintained in the same orientation as they slide down the array of slant racks. At the lower end of the bottom slant rack, the articles are dispensed, by a tilting table dispenser, in the same order in which they were introduced onto the top slant rack.
