Radio Telegraphy

_ A New Invention * MAZING claims were made recently by an inventor in London concerning the transmission of messages at very high speed. ‘Ten thonsand words it was stated could be transmitted by telegraph in a minute; BHmpire newspapers could be published simultaneously in London, Sydney, Cape Town, Montreal, and Calcutta, including pictures, the whole contents of a large daily newspaper being faithfully transmitted to those. distances in a few minutes. The Chief Dingineer of the Telegraph Department, Mr. A. Gibbs, was greatly surprised at the rate of transmission ‘mentioned-ten thousand words per minute. He stated that there has been no mention of any such system in any of the recent technical journals. Possibly, he remarked, the new invention depends upon some method of picture transmission. It is already possible, of course, to set up newspaper type at distances of hundreds of miles, but that does not refer to pictures, which ~ require individual treatment. At pres- . ent the usual speed, as employed in this Dominion is 40 words a minute. Thanks to what is known as the multiplex system, it is possible to use four two-way channels over the same line and thus greatly expedite the work. In some countries where considerable quantities of Press messages are handled speeds up to 250 words a minute are achieved. The new system mentioned, though, must make use of some method altogether different from-current practice. Mr. Gibbs does not see any possibility of this new invention being employed in New Zealand for many years.
