Data transmission by division of digital data into microwords with binary equivalents

Claim 3

Apparatus for the automatic electronic transmission of data, comprising an electronic transmitter and an electronic receiver, the transmitter comprising means for inserting into the transmitter in digital form the data to be transmitted in the form of a series of microwords each consisting of three bits whose different arrangements correspond each to a different one of eight possible decimal integers, means for electronically counting the number of microwords in said series, means for electronically converting each said microword into a train of symmetrical pulse pairs followed by a pause, the number of pulse pairs in each said train being equal to the integer that corresponds to the associated microword binary meaning, means for transmitting said trains of pulse pairs with interspersed pauses to said receiver, said receiver comprising an electronic counter for counting the pulse pairs of each said train, means for resetting said counter during each said pause, means for electronically reconstructing in said receiver each microword that corresponds to the number of pulse pairs counted during each pulse train, means for electronically counting the number of microwords thus reconstructed, and, when said number of microwords thus reconstructed equals said number of microwords in said series, means for electronically producing an output of said reconstructed microwords, thereby reconstructing the transmitted data in the form of the same said series of microwords.

Claim 4

Apparatus for the automatic electronic transmission of data, comprising an electronic transmitter and an electronic receiver, the transmitter comprising means for inserting into the transmitter in digital form the data to be transmitted in the form of a series of microwords each consisting of three bits whose different arrangements correspond each to a different one of eight possible decimal integers, means for electronically counting the number of microwords in said series, means for electronically converting each said microword into a train of symmetrical pulse pairs followed by a pause, the number of pulse pairs in each said train being equal to the integer that corresponds to the associated microword binary meaning, means for transmitting said trains of pulse pairs with interspersed pauses to said receiver, said receiver comprising an electronic counter for counting the pulse pairs of each said train, means for resetting said counter during each said pause, means for electronically reconstructing in said receiver each microword that corresponds to the number of pulse pairs counted during each pulse train, means for electronically counting the number of microwords thus reconstructed, and, when said number of microwords thus reconstructed equals said number of microwords in said series, means for electronically producing an output of said reconstructed microwords, thereby reconstructing the transmitted data in the form of the same said series of microwords.

Claim 5

Apparatus as claimed in claim 2, said transmitter comprising a register the input of which is the digital data of required length to be transmitted and the output of which in said microwords of three bits each, a three-stage counter of the transmitted pulse pairs coming from a generator, a comparator which compares in binary terms the microword with the content of the counter and stops the generation of the pulse pairs when there is equality thereby creating a said pause between pulse trains, and a transducer for inserting said pulse pairs into said transmitting means, said receiver comprising a transducer which draws said pulse pairs from said transmitting means, a three-stage counter which counts the pulse pairs received, a circuit for detecting said pauses which controls the output of the microwords from the last-named counter, and a register which receives the microwords and in which the original digital data is reconstructed.
