    • A conveyor is mounted on the upper surface of an elongated frame. At one end of the conveyor is provided a retriever assembly for retrieving a stack of material as from the exit bin or tray of a printer or copier. The retriever has elongated fingers sandwiched between runs of the conveyor. These fingers are moved horizontally and vertically so as to move out from the conveyor, pick up a stack of material, bring it back and deposit it on the conveyor. Independent motor operated mechanism effects this vertical and horizontal movement of the fingers. The conveyor is of sufficient length to store several stacks of material and operation of the conveyor and the retriever is controlled to retrieve and store the stacked material.
    • 输送机安装在细长框架的上表面上。 在输送机的一端设置有用于从打印机或复印机的出纸槽或托盘取回一堆材料的检索器组件。 回收器具有夹在输送机的行程之间的细长指状物。 这些手指水平和垂直地移动,以便从输送机移出,拿起一堆材料,将其带回并将其沉积在输送机上。 独立的电机操作机构会影响手指的垂直和水平运动。 输送机具有足够的长度以存储多个材料堆叠并且输送机的操作,并且回收器被控制以检索和存储堆叠的材料。

    • A three level network microprocessor based nodal architecture for a fiber optic local area network communication system is disclosed in which the processing responsibility for establishing a voice, video or data communication link between an initiating I/O device and a recipient I/O device and for subsequent two way data exchange between the initiating and recipient devices are shared between three levels of digital processing capability in such manner as to demand the least amount of time from the highest, most intelligent processing level common to all devices thereby making more efficient use of its processing capability as an overall supervisory processor. Each I/O device whether it be a digital terminal, computer or telephone set interfaces with a nodal system through a middle level of processor. An initial communication request from any device at the middle level generates an interrupt command to the highest supervisory processing level which responds to the interrupt, resulting in the identification of the desired recipient station by recalling from storage, associated with the highest level processor, routing information required in establishing a communication link with the desired recipient device. That information is provided to the processor at the middle level associated with the initiating device. That processor completes the link if the recipient is local to it. Otherwise the addresse or recipient device identifying codes are communicated from the middle level to a third level processor responsible for effecting the actual routing of the communication.
    • 公开了一种用于光纤局域网通信系统的基于三电平网络微处理器的节点架构,其中在起始I / O设备和接收者I / O设备之间建立语音,视频或数据通信链路的处理责任, 发起和接收设备之间的后续双向数据交换在数字处理能力的三个级别之间共享,以便从所有设备共同的最高,最智能的处理级别中要求最少的时间量,从而更有效地利用其 作为整体监控处理器的处理能力。 每个I / O设备无论是数字终端,计算机还是电话机通过中间级处理器与节点系统接口。 来自中间级别的任何设备的初始通信请求产生中断命令到最高监控处理级别,该中断命令响应中断,从而通过从与最高级别处理器相关联的存储器调用来确定所需接收方站点的路由信息 与所需的接收设备建立通信链路所需要的。 该信息被提供给处于与发起设备相关联的中间级处理器。 如果收件人是本地的,则处理器完成链接。 否则,地址或接收方设备识别码从中间级传送到负责实现通信的实际路由的三级处理器。
