Abstract

976, 697. Electric selective signalling systems. TELEFONAKTIEBOLOGET L.M.ERICSSON. Sept. 27, 1963 [Sept. 27, 1962], No., 38276/63. Drawings to Specification. Heading G4H. Cyclic scanning in a field station system, for example in a railway signalling system, is achieved by having each field station call the next. This avoids transit time delay which would normally occur when very remote field stations are called direct from the central station.
