An electromagnetic field signal communications system () is based on a specially configured sending transducer (), having electrical conductors () wound onto a generally circular core () including an air gap () from which its electromagnetic fields () are generated when excited with input electrical audio or data () signals. The transducer () transmits by projecting these electromagnetic fields () onto adjacent signal receiving transducers () that transform the electromagnetic field () into proportional electrical signals. The electromagnetic fields () are transformed by a receiving transducer () located in an adjacent hearing aid device () such that input audio electrical input signals, which are processed by circuitry (), bypass the hearing aid microphone () and are routed to the eardrum speaker (). The transducer's () effectiveness is due in part to its ability to reduce environmental electromagnetic interference when excited with an electrical excitation signal () in lieu of or in addition to voice or date signals ().

A multipurpose document feeder, reproducing machine employing a document feeder, the process for operating the document feeder being adapted to copy in either a continuous form feeding mode of operation or an alternative document feeding mode of operation such as semi automatic document feeding. The continuous web support system when moved to its operative position automatically conditions the feeder and reproducing machine to copy in the continuous web mode of operation. An idling pin wheel which engages holes in the web edge is utilized to control incremental feeding of the web during copying and also for sensing jams or tears in the web.

A compact single bin finisher adaptable to form collated sets of copy sheets outputted from a copier/duplicator. The finisher includes an output tray adapted to support the collated sets and to support copy sheets during accumulation of a set. A set accumulation module having an accumulation platform is disposed in a plane which is displaced both horizontally and vertically from the output tray. A transport device carries sheets into the accumulation module. A predetermined number of sheets form a set which may be stapled and is ejected onto the output tray.
