Abstract: ABSTRACT OF THE DISCLOSURE A plurality ? of data blocks, each comprised of at least two data words and a parity word associated bit for bit with the data words, together with an error correcting code word associated with each data and parity word, are transmitted in interleaved relation.  ? data words and associated error correcting code words followed by ? parity words and associated error correcting code words and followed by ? data words and associated error correcting code words, all transmitted in seriatim, are received and stored, and each error correcting word is decoded to ascertain the presence of an error in each received data or parity word.  All of the data words and the parity word in a block are read out simultaneously, together with an indication of the presence of errors in any of the read out data and parity words; and in the event of an error, an erroneous data word is corrected in accordance with the parity word in that block; and if parity correction cannot be achieved, an erroneous data word is replaced by the average of the data word in the preceding and next following data block. In a preferred application, each data word is formed of a plurality of multi-bit samples of, for example, interleaved left channel and right channel audio signals.  The overall length of ? data words and associated error correcting words plus ? parity words and associated error correcting words is greater than the longest expected error length, such as a burst error.

Abstract: ABSTRACT         A first stream of non-overlapping spaced-apart sheets which move at a high speed is converted into a second stream of partially overlapping sheets by braking successive sheets of the first stream and deflecting the trailing portions of braked sheets laterally to enable the oncoming foremost sheets of the first stream to catch up with and partly overlap the preceding sheets.  When the first stream exhibits a gap as a result of the absence of one or more sheets, or  independently of the presence or absence of gaps, the deflection of the braked sheets is repeated at a location which is nearer to the braking station to thus insure that the trailing portion of the braked sheet preceding a gap is deflected laterally immediately before the sheet which follows the gap catches up therewith.   The deflection of trailing portions which precede gaps in the first stream is effected by suction.  The locus of such deflection can be shifted lengthwise of the path for the sheets in dependency on changes of the ratio of the speeds of first and second streams, on changes of the width of clearances between the sheets of the first stream and/or in dependency on changes of the length of sheets.

Abstract: COMMUNICATION CIRCUIT                         A B S T R A C T             The disclosure relates to a four conductor circuit arrangement providing two communication channels between a con-trol unit and a terminal device.  Power feed and bi-directional signalling are accomplished simultaneously over the same four conductors used for the two communication channels without inter-ference.  The signalling from the control unit to the terminal is accomplished by means of a voltage modulator circuit in the control unit by which voltage pulses are transmitted via a phan-tom circuit arrangement over the four conductors to the terminal unit.  The voltage pulses are sensed from the phantom circuit in a data receiver which is located at the terminal unit.  Connected to the phantom circuit in the terminal unit is a voltage regula-tor circuit which receives power from the control unit via the four conductor phantom circuit interconnecting the control unit and the terminal.  In series with the voltage regulator circuit is a constant current sink and an inductor.  A current modulator circuit is provided in parallel for impressing current data pul-ses generated in the terminal onto the phantom circuit, which are, in turn, received by a receiver circuit in the control unit.           A preferred data format is disclosed as a method for transmitting information between the control units and the termi-nal.           The preferred embodiment for the disclosed four con-ductor communication circuit and  he disclosed data format is in a key telephone system in which the control unit is a station card in a key service unit and the terminal is a key telephone station set.                             - i -

Abstract: Abstract of the Disclosure A cassette that holds a large format photographic film unit of the self-developing type in a film plane for exposure to x-rays has a generally rectangular housing and a pressure plate disposed in the housing.  The walls of the housing are in fixed relation to one another.  A variable gap film-loading opening is defined at one transverse end of the housing and a second variable gap opening is provided at the opposite end for sliding removal of an opaque envelope surrounding the film unit.  Springs resiliently urge the pressure plate into intimate, continuous contact with the film unit which also places the photosensitive layer of the film unit in intimate, continuous contact with an x-ray sensitive phosphor layer disposed adjacent the film plane. Operating members such as spring-loaded slide rods mounted in the longitudinal edges of the cassette are operatively connected to the pressure plate through one or more cam surfaces,  Movement of the operating members in a direction parallel to the film plane is translated into a transverse movement of the pressure plate away from the film unit.  This movement of the pressure plate releases the film unit and increases the housing openings to allow the sliding insertion and removal of the film unit and the sliding removal of the envelope.  Light seals are preferably provided at the openings to ensure that the cassette is light tight when the film unit is loaded in the cassette for exposure.

Abstract: ABSTRACT OF THE DISCLOSURE A normally inactive sound signal generator is supported from the rotatable axle of each railway car in a train and actuable to generate a predetermined signal in response to a hot box condition.  Electrically operable signal receivers coupled to electrically operable radio signal transmitters are spaced along the railroad track at predetermined intervals which may be 4,000 to 6,000 feet apart and the receivers and transmitters are operable on low magnitude current, such as provided in the rails of the track for Centralized Train Control Systems. The engine ant caboose of a freight train are provided with radio signal receivers actuated by on-board current and the caboose receiver is operative to actuate visual and audible signals as well as an electrically operated air brake dump valve (through a time delay mechanism) and the engine receiver is operable to also actuate visual and audible signals and a relay (through a time delay mechanism) electrically connected to the engine electrical control system for automatically reducing the power output of the engine.  If the hot box condition detected is too distant from the actuated track side radio signal generator to receive its low magnitude radio signal, then the low magnitude signal is received by the caboose mounted radio signal receiver as it passes close by the actuated trackside radio transmitter.

Abstract: A PRINTER RIBBON SUPPLY MECHANISM WITH END OF RIBBON      DETECT EXPEDIENT WHICH REDUCES RIBBON DRAG               ABSTRACT OF THE DISCLOSURE   In a conventional ribbon supply spool structure which comprises a supply of ribbon wound on a hub rotat-able about and axially movable with respect to a hub receiving member on which the hub is seated and which is coaxial with respect to the hub, an improved end of ribbon detection device is provided by the combination of deflectable spring means within the spool hub which exert a force when deflected having a first force component acting against but restrained by wound ribbon on the hub and a second component acting along the hub axis.  A spring tensioned member exerts a force along the hub axis which opposes the component of force of the deflectable spring along the hub axis.  In this manner, the deflec-table spring and the spring tensioned member are maintained in static equilibrium at a selected point along said axis so long as the deflectable spring is restrained by a predetermined minimum of ribbon remaining wound on the hub.  This predetermined minimum of ribbon remaining wound is indicative of the end of ribbon.  In the preferred embodiment this is in effect the point where the ribbon becomes substantially unwound.
