WIRELESS PICTURES

IN BUSINESS AND THE NOME GREAT PROMISES FROM BERLIN Further experiments in the nei# wireless picture system ( Telcfuuken* Carolus-Simens), to bo installed between Berlin and A’icnna, will begin shortly, says the Berlin correspondent of the ‘ M ruing Post.’ The general ]mb lie in cither country will not be able to profit by a regular postal service until a further stage in development has been reached.

The ‘ Carlogram,' which is the official name of tho new photographed document, has very nearly reached perfection, and tho “ Carlograph,” which photographs it, will, if present hopes materialise, soon bo installed in all loading German post offices. At present the wireless station at Koingwusterhauseu is still being used for experiments. How seriously this new system is taken may be gathered from a statement by Dr Hans Bredow, Wireless Commissioner in the German Ministry of Posts, published in the ‘Berliner Xageblatt.’ Df Bredow's technical experience leads one to regard his expectations a§ legitimate. He is' supported in his opinions by Count Arco, technical director in tho Telefunkeu Company, which is perfecting the present process according to the directions of Professor Carolus, of Leipzig. Professor Carolus’s experiments in speed transmission are said to have resulted in attainments that open up “ limitless ” vistas. At present pictures measuring ten by ten centimetres are transmitted in 20sec to JOscc over long distances.

Dr Bredow, enumerating the advantages the general public may expect to receive from wireless pictures, places first in 'importance the revolution in corresponding with the Antipodes. Photographed letters and telegrams will be transmitted so quickly that it will be possible to write and receive three or four letters to Australia, supplying question and answer within twelve hours. Ships at sea and aircraft possessing the apparatus can be reached the same way. The Morse system appears obsolete in comparison, and telephoning loses its charm when it is considered that 1,000 words in shorthand can be transmitted on cylinders of tho size used at present. The advantage of tho new method to commerce and industry is stressed. Dr Bredow mentions the possibility to business when banking houses can obtain the exact facsimiles of cheques, diagrams of exchange rates, and the like, and photographs of pages of ledgers, as well as being able to furnish clients with information merely by sending them photographs of the newspaper in which a particular report appeared. Tho prompt despatch of facsimile finger prints and footmarks should also assist tho ends of justice. Pictures of tho tools or personal property found on the persons suspected can be identified at the other end, and so save valuable time lost in the detention of innocent persons or lead to the conviction of the suspect. Another point Dr Bredow raises is tho changes to he expected in journalism, which he considers of particular interest to “the explorer in foreign countries,” a term which may doubtless he -applied to the average “special correspondent.” He believes that some day this person will carry with him a special wireless photography short nave transmitter with which he can reach the next relay station. The newspaper will thus lie put in immediate possession of any pictures of reproductions of tho local press, or his own photographs of aborigines and their surroundings in time, it is to be presumed, for the next edition. This may bo extended to his accompanying message, so that the trouble of getting to a telegraph office before a rival will become a thing of the past. Dr Bredow points out another enormous saving of time and trouble by sending out to ships at sea the weather charts in facsimile instead of as now; by code. Dr Bredow mentions as one of his last points one that in prt-war Germany would have been in the foremost place—the military advantages of the wireless picture. Sketches as well as messages can he sent from one outpost to another in the air, on land and at sea. Mistakes in deciphering code messages need no longer occur a.ud cause blunders.

Most fantastic dream of all, however, is tiie possibilities in every home of the picture-radio apparatus besides the crystal set or the loud speaker. H at certain hours of the day pictures are broadcast to appear in every private screen installed, the lectures, particularly those of scientilic interest, may he 'made enormously more valuable. Dr Bivdow, who lias been responsible for the whole construction of tlio Herman “ Unndfunk.” appears to consider this a probability before many months arc over.
