Abstract

964, 502. Electric selective signalling systems. HASLER A. G. Dec. 1, 1960 [Dec. 2, 1959], No. 41344/60. Heading G4H. A circuit for converting an "a out-of b" code into an "α out-of #" code, # < b, is characterized in that unless precisely a input pulses are applied to the circuit no output pulses are produced. As described input pulse combinations in a "3 out of 7" code are applied in true and inverse form by devices 11, 16, Fig. 4 to a first diode matrix D 1 , which results in one of the vertical conductors fa'ling in potential, which, in turn, causes a second matrix of diodes D 2 to apply a combination of " 2 out of 5" pulses on leads Ai to A 5 to an output device 13. Should a spurious pulse combination (one not containing precisely 3 pulses) be applied to the first diode matrix no output at all is produced so that a diode gate D 3 opens and gives an error indication via an amplifier 15.
