    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: 1375747 Electro-photographic printing apparatus INTERNATIONAL BUSINESS MACHINES CORP 17 Nov 1972 [22 Dec 1971] 53123/72 Heading G2H Toner remaining on electro-photographic surface 7 after transfer of a developed image is removed by an electrically biased magnetic brush 4, after the electrostatic image has been erased by light 23, and is returned to developing apparatus 1 for re-use by electrically biased magnetic brush 2. For example the toner may be returned by being attached to the surface 7 when the apparatus if not producting prints, and corotron 22, (which usually assists transfer) gives the surface a charge which attracts toner from the brush 4. Alternatively the apparatus may be made to attach bands of returned toner to the surface 7, between positions formerly occupied by images to be developed, or toner return may be carried out by separate end portions of brush 4 and surface 7, or by auger conveyors operating independently of development. Preferably the developing apparatus 1 contains magnetic carrier particles with tetrafluorethylene coats, which give a positive charge to the toner, and the cleaning apparatus 3 contains magnetic carrier particles coated with ethyl cellulose, which places a negative charge on the toner.

    Abstract: A continuously operating transfer reproduction apparatus includes a cyclic control unit which automatically effects alternate redevelopment and reimaging cycles when reproducing multiple copies of the same master. An electrophotographic plate travels in a closed loop past a moving optical system which images the plate with a light image of the master creating a latent electrostatic image on the plate. The latent image is developed at a developing station and transferred to a substrate at a transfer station as the plate travels therepast. Increased throughput speed is achieved by effecting a fixed number of redevelopment cycles while the moving optical system is resetting. Thus, the plate continues its travel past the resetting optical system to the developing station where the latent image is redeveloped and thence to the transfer station for transfer of the developed image to a second substrate. The plate is then cleaned and charged prior to being reimaged with the light image of the same master, and the process continues until the requisite number of copies have been reproduced. In one embodiment, multiple imaging areas, preferably an odd number thereof, are located on the plate facilitating rapid alternate imaging and redevelopment cycles.

    Abstract: PHOTOCONDUCTOR CLEANING STATIONS A photoconductor member is cleaned by a rotating fiber brush. The cleaned particles are knocked from the brush by a knock-off bar causing substantial wear on the brush. To compensate for the wear, both the knock-off bar and the fiber brush are adjusted for maintaining cleansing contact between the photoconductor member and the brush, plus the brush with the knockoff bar. In a preferred form of the invention, the fiber brush also is an air impeller for entraining cleaned particles from the photoconductor drum into a disposal station which, by way of example, may contain a scavanging roll and an air filter. The adjustments are such that the air impeller properties of the rotating brush are maintained throughout the life of the brush.
