摘要： A method of railroad track control includes partitioning a physical track block into a plurality of virtual track blocks, the physical track block defined by first and second insulated joints disposed at corresponding first and second ends of a length of railroad track. The presence of an electrical circuit discontinuity in one of the plurality of virtual track blocks; is detected and in response a corresponding virtual track block position code indicating the presence of the discontinuity in the one of the plurality of virtual track blocks is generated.

摘要： A vital communication system includes a conventional, that is non-vital, communication link, a transmitter and a receiver. The transmitter is responsive to input data, and provides for encoding and transmission as well as checking of its own input arrangement. The encoding and transmission is effected by a program driven device, but as loaded the program is incomplete. The checking produces certain check words which are used to complete the program so that only in those instances in which the checks are passed, will an appropriate message be transmitted. The receiver includes a decoder logic as well as a decoder check logic. The messages are decoded and applied to an output device. The decoder check logic checks that the information supplied to the output device corresponds to the decoded information, and if the check is passed, the output device is enabled to output the information to the outside world.

摘要： Synchronizing and coordination apparatus and circuit arrangement, at a junction terminal in a coded carrier remote control system where two branch communication channels diverge from the main channel from the control office, to establish and enforce a preselected order of priority for code transmission in both directions between the control office and stations connected along the main and branch channels. Each section of the channel network is provided with separate carrier apparatus to transmit codes in both directions. Retransmission means at the junction repeat control codes received from the office to all branch and satellite stations and indication codes received from these stations to the office office. Control codes from the office and indication codes from main channel stations are given first and second transmission priority, respectively. Indication codes from junction terminal satellite stations are third in priority order, over similar codes from stations along both branch channels. This is enforced by locking out such branch stations in response to the initiation of a code from a satellite station. Stations along a selected one branch are given the next order of priority, also enforced by locking out the other channel stations, which thus have the lowest priority for transmitting codes.
