    Abstract: A time-division signaling system employing a transmitter and a receiver which communicate in recurrent operating cycles over a common transmission medium. The transmitter is contructed to transmit during an operating cycle time-spaced interleaved indexing and signaling voltage pulses which differ in respective maximum voltage levels. Discrimination between these two different kinds of pulses at the receiver is made on the basis of a comparison of their respective maximum voltage levels with a reference voltage level which has been generated by preceding pulses. The system includes circuitry which assures synchronization between the transmitter and receiver; and a modification of the system further includes circuitry which prevents the receiver from producing a responsive output to any signaling pulse which is received at the time that the transmitter and the receiver are out of synchronization.

    Abstract: An electrical supervisory signaling system employing a plurality of McCulloh-type pulse transmitters which are operable selectively to transmit over a line one or more like groups, or ''''rounds,'''' of time-spaced, numerically coded pulses. Single''''round'''' and multiple-''''round'''' transmissions are used to indicate different monitored conditions. Receiving these pulses in the system is an interpreter which, through examining the time spacings between successive pulses, both distinguishes the transmissions from the different transmitters, and indicates whether a transmission from a given transmitter contains one or more ''''rounds'''' of pulses.

    Abstract: Apparatus in an electrical signaling system for registering or making a record of signals produced by a plurality of remote signaling devices. The apparatus includes memory circuitry that immediately notes, and remembers, which, if any, devices have transmitted signals, search circuitry which recurrently searches the memory circuitry for such information, and printing mechanism which is actuated immediately in response to information thus uncovered by the search circuitry to print a permanent record reflecting such information. Searching of the memory circuitry stops during intervals of operation of the printing mechanism.
