Abstract: ABSTRACT OF THE DISCLOSURE A data communication system includes a communicating medium and a plurality of transceivers connected to the medium, each including a transmitter for transmitting phase-encoded data onto the medium and a receiver for receiving phase encoded data communicated on the medium by another transceiver. A digital phase decoder is coupled to the receiver of each transceiver for decoding the data received and applying at its putput a decode signal representative of the character of the received data. The decode signal is at a predetermined value whenever data communicated on the medium by another transceiver is received by the subject receiver during the time the subject transmitter is transmitting data onto the medium. Circuitry is included for interrupting the transmission of data whenever the decode signal is detected to be at said predetermined value.

Abstract: SECRETARIAL SHIFT MECHANISM  FOR AN ELECTRIC KEYBOARD     Abstract of the Disclosure A secretarial shift mechanism which includes two shift keyswitches and one shift lock keyswitch is disclosed.          The two shift keyswitches have T-shaped actuating bars secured to their plungers.  The shift lock and release keyswitch has a generally C-shaped wire retainer spring placed around its housing which is utilized to secure a hook on a latching finger on a ledge that is formed on the plunger of the shift lock keyswitch.  The latching finger is secured to an elongated torsion bar which has a pair of arms at the ends of the bar that are bent toward the two shift keyswitches.  The torsion bar is held at its ends against the frame that holds the keyswitches of the keyboard by clamping caps that project from the shift keyswitches and have grooves in them that receive the torsion bar therein.  When the shift lock keyswitch is depressed, a hook on the latching finger that is secured at the torsion bar engages a ledge on the plunger of the shift lock keyswitch and holds it down.  Depression of either of the shift keyswitches causes the T-bar on the keyswitch to engage the bent arms on the torsion bar, which in turn results in twisting of the torsion bar sufficiently to deflect the latching finger so the lock is off of the ledge which releases the shift lock keyswitch from its actuated condition.

Abstract: ABSTRACT     In a digital subscriber set in which a line receiver receives, when enabled, digital signal bursts from a master terminal and in which a line driver sends, when enabled, digital signal bursts to the master ter-minal in synchronism with the signal bursts received from the master ter-minal, a circuit temporarily disables and enables the line receiver and the line driver to send a call originating signal to the master terminal and then enables and disables the line receiver and the line driver continuously until the synchronism is established by at least one digital signal burst which the master terminal supplies to the subscriber set in response to the call originating signal.  The circuit recovers the synchronism within a shortest possible time when the synchronism is put out of order by some reason or another during communication.

Abstract: CALLING LINE TRACING SYSTEM AND IDENTIFICATION DETECTOR           ABSTRACT           A calling line tracing system and identification detector arranged for identifying the identity number of a calling station connected through a series of switching ex-changes to a called station in any type of telephone network.          The identification system is started automatically whenever a telephone exchange receives a call addressed to a local line designated with a special category or shunt. The local ex-change, once the special category or shunt of the addressed line is sensed, automatically starts a change in the signal-ling sequence and disengages its control unit from the calling process, passing the control of the telephone call to the identification detector which is coupled to the addressed line. The identification detector starts a signalling process with the telephone exchange where the call has been originated to obtain all available information at that exchange about the calling telephone station. Once all available information has been received and entered in the memory of the detector, the calling process is completed regularly. The calling station identity information is shown on a display panel or stored in the detector memory for later retrieval.
