Abstract
Abstract A method of and communication system for transmitting data, such as telegrams, messages and information, from a transmitting station to a receiving station, both stations possessing transmitter and receiver sections. The data to be transmitted, such as telegrams, is provided, by means of an identification device of the transmitting station, with names from a predetermined list in a manner such that such data can be detected by an evaluation device of the receiving station and identified in its sequence. The predetermined list of names is known to the evaluation device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A method of transmitting telegrams between a transmitting station and a receiving station, each having a transmitter section and a receiver section, comprising the steps of: providing at the transmitting station an identification device having a list of names for marking the transmitted telegrams; providing at the receiving station an evaluation device having knowledge of the list of names and their sequence for detecting and identifying such names in the transmitted telegrams; applying by means of the identification device of the transmitting station to the telegrams to be transmitted a respective name from said list of names; transmitting the telegrams with their names from the transmitting station to the receiving station; detecting by means of the evaluation device in the receiving station the names and their sequence in the incoming telegrams; requesting, upon reception at the receiving station of a telegram which is garbled or lost, by means of the receiving station, and while identifying the name of the garbled or lost telegram, the transmitting station to again transmit such telegram; and controlling the receiving station, by means of said evaluation device, such that telegrams which have been properly received in the interim are not evaluated until the arrival of the previously lost or garbled telegram.
Claim 2
Independent Claim
206 words
A method of transmitting telegrams between a transmitting station and a receiving station, each having a transmitter section and a receiver section, comprising the steps of: providing at the transmitting station an identification device having a list of names for marking the transmitted telegrams; providing at the receiving station an evaluation device having knowledge of the list of names and their sequence for detecting and identifying such names in the transmitted telegrams; applying by means of the identification device of the transmitting station to the telegrams to be transmitted a respective name from said list of names; transmitting the telegrams with their names from the transmitting station to the receiving station; detecting by means of the evaluation device in the receiving station the names and their sequence in the incoming telegrams; requesting, upon reception at the receiving station of a telegram which is garbled or lost, by means of the receiving station, and while identifying the name of the garbled or lost telegram, the transmitting station to again transmit such telegram; and controlling the receiving station, by means of said evaluation device, such that telegrams which have been properly received in the interim are not evaluated until the arrival of the previously lost or garbled telegram.
Claim 3
Dependent Claim
73 words
The method as defined in claim 1, further including the steps of: sending the telegrams in the form of telegram blocks each composed of a number of telegrams; after transmitting a telegram block composed of a given number of telegrams only then transmitting a further telegram block after the transmitting station has transmitted a completion signal to the receiving station and the receiving station has transmitted a receipt signal to the transmitting station.
Claim 4
Dependent Claim
224 words
A communication system for transmitting telegrams in a telegram block between transmitting and receiving stations, wherein the transmitting station has a transmitter section having an identification device and receiver section connected at its input and the receiving station has a receiving section having an evaluation device and transmitter section connected at its output, and wherein the telegrams are provided with an identification character for checking of the correctness of the arriving telegrams, and telegrams lost or garbled upon transmission are retransmitted, comprising: an identical list containing the individual names for the identification of the individual telegrams of a block present at both the transmitting and receiving stations; individual names from said list being added to the telegrams transmitted between said stations, according to a coordinated sequence between said stations; and said evaluation device, after the completion of the transmission of each individual telegram, checking said individual name transmitted with each telegram, based upon said coordinated sequence, and, in the case of non-coincidence of the individual transmitted name with the name present on the list at the receiving stations, requesting retransmission of the lost or garbled telegram, by indicating its name, whereas simultaneously, the remaining telegrams of said block are transmitted and are intermediately stored until the arrival of said requested repetition of said lost or garbled telegram, whereupon said intermediately stored telegrams are evaluated.
Claim 5
Dependent Claim
224 words
A communication system for transmitting telegrams in a telegram block between transmitting and receiving stations, wherein the transmitting station has a transmitter section having an identification device and receiver section connected at its input and the receiving station has a receiving section having an evaluation device and transmitter section connected at its output, and wherein the telegrams are provided with an identification character for checking of the correctness of the arriving telegrams, and telegrams lost or garbled upon transmission are retransmitted, comprising: an identical list containing the individual names for the identification of the individual telegrams of a block present at both the transmitting and receiving stations; individual names from said list being added to the telegrams transmitted between said stations, according to a coordinated sequence between said stations; and said evaluation device, after the completion of the transmission of each individual telegram, checking said individual name transmitted with each telegram, based upon said coordinated sequence, and, in the case of non-coincidence of the individual transmitted name with the name present on the list at the receiving stations, requesting retransmission of the lost or garbled telegram, by indicating its name, whereas simultaneously, the remaining telegrams of said block are transmitted and are intermediately stored until the arrival of said requested repetition of said lost or garbled telegram, whereupon said intermediately stored telegrams are evaluated.
Claim 6
Dependent Claim
50 words
The communication system of claim 3, wherein: a completion signal is transmitted between said stations upon the completed transmission of a telegram block, a receipt signal is then transmitted between said stations; and a further telegram block is transmitted between said stations after said completion and receipt signals are transmitted.
