Abstract
Abstract An arrangement for effecting a variable modification of information used to control a printer unit of a teleprinter has a first store containing information for basic functions required to control the printer unit. A first decoding circuit analyzes received teleprinter characters and drives the first store. A second store contains information required to modify the basic functions. A second decoding circuit analyzes the count reached by a counter and drives the second store. A setting up matrix is sampled by the counter and feeds its output via a multiplexing circuit to a comparator device. The comparator device compares the result of a sampling of the setting up matrix and a read out from the second store with the received teleprinter character, and, if the result is positive, the comparator device causes information contained in the second store to be combined with information from the first store to create a modified information feed to the printer unit.

Claim 1
Independent Claim
185 words
An arrangement for effecting a variable modification in information used to control a printer unit of a teleprinter, comprising: a. a first store for controlling the printer unit, said store containing information for basic functions required to control the printer unit; b. a first decoding circuit for analyzing received teleprinter characters and for driving the first store; c. a second store containing information required to modify the basic functions; d. a counter; e. a second decoding circuit for analyzing the count reached by the counter and for driving the second store; f. a setting up matrix scanned via the counter; g. a multiplexing circuit connected with the counter and the setting up matrix in which a selection criterion is formed by means of a result from scanning the setting up matrix; and h. a comparator device in which the selection criterion resulting from the scanning of the setting up matrix and an address read out from the second store are compared with a received teleprinter character, and, if the results are positive, the information contained in the second store being relayed to the printer unit.
Claim 2
Dependent Claim

An arrangement for effecting a variable modification in information used to control a printer unit of a teleprinter, comprising: a. a first store for controlling the printer unit, said store containing information for basic functions required to control the printer unit; b. a first decoding circuit for analyzing received teleprinter characters and for driving the first store; c. a second store containing information required to modify the basic functions; d. a counter; e. a second decoding circuit for analyzing the count reached by the counter and for driving the second store; f. a setting up matrix scanned via the counter; g. a multiplexing circuit connected with the counter and the setting up matrix in which a selection criterion is formed by means of a result from scanning the setting up matrix; and h. a comparator device in which the selection criterion resulting from the scanning of the setting up matrix and an address read out from the second store are compared with a received teleprinter character, and, if the results are positive, the information contained in the second store being relayed to the printer unit.
Claim 3
Dependent Claim
72 words
An arrangement as claimed in claim 1, characterized in that the setting up matrix is designed as a diode matrix in which each intersection point is assigned a storage position in the second store, the setting up matrix being completely sampled via the counter each time a teleprinter character is received, selection of the storage positions in the second store being performed by variable distribution of diodes in the setting up matrix.
Claim 4
Dependent Claim
62 words
An arrangement as claimed in claim 1, characterized in that storage positions having command and address sections in the second store are in each case assigned to a specific teleprinter character via their address sections, and in their command sections contain the information required to modify the information of the basic function assigned to the specific teleprinter character in the first store.
Claim 5
Dependent Claim
119 words
An arrangement as claimed in claim 1, characterized in that the outputs of address sections of the second store are connected to the comparator device and the outputs of command sections of the second store are connected to a buffer store which can be controlled by the comparator device, the command information for the second store being transferred into the buffer store in the presence of a selection criterion and in the event of a positive comparison between the address read out of the second store and the received teleprinter character, and a gating arrangement connected between the outputs of the first store and the outputs of the buffer store for analyzing information from the first and second stores.
Claim 6
Dependent Claim
51 words
An arrangement as claimed in claim 4 characterized in that the gating arrangement contains in respect of each bit of the information within the basic function intended for modification an exclusive-OR gate whose inputs are in each case connected to the corresponding outputs of the first store and the buffer store.
Claim 7
Dependent Claim
115 words
An arrangement as claimed in claim 1 characterized in that the second decoding device is connected to a sequence detection circuit for the comparison of at least two successive teleprinter characters to form a sequence criterion, addressing of the second store being performed by analyzing the sequence criterion and the count reached by the counter sampling the setting up matrix and in the event of a selection criterion being produced and with a positive comparison between the teleprinter characters respectively read out from address sections of the second store and forming the sequence, command information being transferred from the second store to a buffer store and passing via a gating arrangement to the printer unit.
Claim 8
Dependent Claim
57 words
An arrangement as claimed in claim 6, characterized in that the sequence detection circuit comprises two intermediate stores to receive successive teleprinter characters, a comparator circuit for comparing the intermediately stored teleprinter characters, a shift-register for receiving the result of comparison, and a detector circuit for analyzing the content of the shift-register and generating the sequence criterion.
