Abstract
Abstract An arrangement for collecting and/or distributing information, comprising a master station and a number of terminal stations, each terminal station being connected to the preceding terminal station via a transmission line, the first terminal station being connected to the master station. All terminal stations are connected to the master station via a number of collecting lines. By transmission of a pulse on the transmission line, the information which is transmitted by the terminal stations to the master station or vice versa is successively received on the collecting lines.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
275 words
A system for distributing information, comprising a master station, output terminal means on the master station for providing an interrogating pulse, a plurality of information signal input terminals on the master station for receiving information pulses, n terminal stations, an interrogating pulse input terminal on each terminal station, an interrogating pulse output terminal on each terminal station, delay means in each terminal station connected to the interrogating pulse input and interrogating pulse output terminals thereof for proviDing a delayed interrogating pulse on the interrogating pulse output terminal in response to an interrogating pulse on the input terminal thereof, a plurality of information signal control terminals on each terminal station corresponding to the information signal input terminals of the master station, means for connecting the output terminal of the master station to the interrogating pulse input terminal of a first of the terminal stations, means connecting the interrogating pulse output terminal of the first terminal station to the interrogating pulse input terminal of a second of the terminal stations, means for connecting the interrogating pulse output of each but the last of the n terminal stations to the interrogating pulse input terminal of a subsequent terminal station, whereby the terminal stations are serially interconnected with the master station and each sequentially receive a delayed interrogating pulse in response to the interrogating pulse provided by the master station, manually controllable distribution means in each terminal station for coupling the delayed interrogating pulse selectively to each of the information signal output terminals thereof, and means connecting corresponding information signal output terminals of the terminal stations in parallel to the corresponding information signal input terminals of the master station.
Claim 2
Independent Claim
275 words
A system for distributing information, comprising a master station, output terminal means on the master station for providing an interrogating pulse, a plurality of information signal input terminals on the master station for receiving information pulses, n terminal stations, an interrogating pulse input terminal on each terminal station, an interrogating pulse output terminal on each terminal station, delay means in each terminal station connected to the interrogating pulse input and interrogating pulse output terminals thereof for proviDing a delayed interrogating pulse on the interrogating pulse output terminal in response to an interrogating pulse on the input terminal thereof, a plurality of information signal control terminals on each terminal station corresponding to the information signal input terminals of the master station, means for connecting the output terminal of the master station to the interrogating pulse input terminal of a first of the terminal stations, means connecting the interrogating pulse output terminal of the first terminal station to the interrogating pulse input terminal of a second of the terminal stations, means for connecting the interrogating pulse output of each but the last of the n terminal stations to the interrogating pulse input terminal of a subsequent terminal station, whereby the terminal stations are serially interconnected with the master station and each sequentially receive a delayed interrogating pulse in response to the interrogating pulse provided by the master station, manually controllable distribution means in each terminal station for coupling the delayed interrogating pulse selectively to each of the information signal output terminals thereof, and means connecting corresponding information signal output terminals of the terminal stations in parallel to the corresponding information signal input terminals of the master station.
Claim 3
Dependent Claim
78 words
A system as claimed in claim 1, wherein the manually controllable distribution means in each terminal station comprises a plurality of switches for selectively supplying the delayed interrogating pulse in the terminal station to the information signal output terminals of the terminal station, and wherein the master station further comprises means connected to each of the information signal input terminals for receiving pulses therefrom and means for counting the pulses from each of the information signal input terminals.
Claim 4
Dependent Claim
49 words
An arrangement as claimed in claim 1, wherein the delay means comprises a first and a second monostable circuit, the first monostable circuit determining the beginning of the pulse which is applied to the subsequent terminal station, the end of said pulse being determined by the second monostable circuit.
