TL;DR: In this article, an error detecting device was proposed for detecting errors of transiission of code signals for printing telegraph apa paratus. But this device is not suitable for the printing of wireless codes.
Abstract: This invention relates to error detecting devices and has particularly to do with the provision of means for detecting errors of transiission of code signals for printing telegraph apa paratus. Printing telegraph code signals are especially susceptible to distortion and to mutilation when transmited...
TL;DR: In this article, an improved means for changing permutation code telegraph signals having a given number of code units to permutation codes having a different number of codes units was proposed.
Abstract: This invention relates to a telegraph code converter, and more particularly to improved means for changing permutation code telegraph signals having a given number of code units to permutation code signals having a different number of code units. In printing telegraph transmitting and repeating...
