MICRO-RAY APPARATUS. NEW STATION AT LYMPNE. London, Jan. 30. The Under-Secretary of State for Air, Sir Philip Sassoon, opened the microray wireless station at Lympne, Kent, by carrying on a conversation with the Under-Secretary of the French Air Ministry, M. de la Salle. The station, from which prolonged secret tests were made by the Air Ministry, transmits on a wave-length of 17| centimetres, and the aerials are only one inch long. In appearance the apparatus is so inadequate as to suggest magic, says the aeronautical correspondent of the Times. The tiny aerial reflects into a lOin. aluminium radiator, giving two-way communication, which cannot be tapped. It is managed by one station using a wave-length of 17 centimetres, and the other using one of 17i- The valves oscillate 1,700,000,000 times a second, and the power needed is about equal to that required for a pocket torch. While two-way speech was proceeding a teleprinter tapped out a telegraphic message on the same circut. The service was introduced with a report on trans-Channel aeroplanes, this eliminating telephoning from Croyden, whence the message was wirelessed to St. Invelgast aerodrome, in France. It is believed that the system can be adapted to aid lighthouse-keepers in conditions of bad visibility. It may also assist the development of television.
