Title: Safety device for a knitting machine.
IPC: D04B15/96
Filed: 1983-06-10
Abstract: A safety device is provided for a knitting machine to ensure that the carriage stops in the case of sudden variation of the speed as a result of an impact or other occurrence such as tangling of the yarn into a ball. The device includes a metal strip formed with equidistant perforations assembled parallel to one of the needle bars of the knitting machine. A bridge integral with the carriage moves along this strip, and has on one side an emitter and on the other a transducer. When the carriage moves the succession of perforations gives rise to pulses of length inversely proportional to the translational speed of the carriage. A CPU processing unit processes the signal obtained after amplification and shaping of the pulses and delivers a STOP signal when a sudden disturbance is detected in the movement of the carriage.

Title: Multiparty line adaptor with privacy feature.
IPC: H04M1/70
Filed: 1984-06-20
Abstract: A respective signalling transmitter (112) is enabled by the polarity reversal on the tip and ring lines and couples a unique identification signal to these lines. A respective signalling receiver (118) responds to an interrogate signal to cause the line adaptor circuit to send a unique identification signal to the subscriber line. A line switch transistor (116) responds to the unique identification signal to enable the line adaptor circuit so that ringing current can be received from the line at the enabled line adaptor circuit and so that none of the disabled line adaptor circuits receives the ringing current. - The switch transistor cooperates with the signalling receiver for receiving the identification signals so that only the calling subscriber and the uniquely-identified subscriber are coupled to the subscriber line. All other subscribers on the multiparty line are disabled and uncoupled so as to maintain the privacy of communication on the line.
