    Abstract: The present case concerns several systems for cleaning a photoconductor of residual toner at a cleaning station and recirculating the toner to a developer station in a copier machine. One embodiment contemplates a fairly continuous accumulation of residual toner in the cleaning unit and a periodic recirculation of the toner to the developer unit. Another embodiment makes use of a cleaning station for performing cleaning of toner from an imaging portion of a photoconductor drum member and concurrent conveyance of residual toner from the cleaning station back to the developer station by another portion of the photoconductor. In still another version, recirculation is performed by augers. In some cases, recirculation is initiated by counter means operative after a predetermined number of cycles.

    Abstract: The invention concerns a dictating system capable of the random recording and arrangement of audio segments, means for digitally recording the positions of such segments after the completion of such arrangement either upon an additional medium or upon the recording medium in a separate track or tracks reserved for such purposes or in locations corresponding to each audio segment giving the location of the next audio segment as defined by the arrangement, or for transmitting such information over a wire or wireless channel; and also concerns a transcription device for use with the above system, either capable of reading such digital information into memory before the beginning of the transcription process or capable of reading information giving the location of the next audio segment as defined by the arrangement during the transcription process, and having means for accessing audio segments on the medium recorded by the above system in the order of the arrangement.

    Abstract translation: 本发明涉及一种能够随机记录和布置音频段的指令系统，用于在完成这种布置之后，在附加介质上或在记录介质上数字记录这些段的位置的装置，该单独轨道或轨道保留用于 这样的目的或对应于每个音频段的位置，给出由该装置定义的下一个音频段的位置，或者用于通过有线或无线信道发送这样的信息; 并且还涉及与上述系统一起使用的转录装置，其能够在转录过程开始之前将这样的数字信息读入存储器，或者能够读取给出在转录过程中由排列所定义的下一个音频片段的位置的信息 处理并且具有用于按照安排的顺序访问由上述系统记录的介质上的音频片段的装置。
