FLIGHT, FEBRUARY 1, 1934 LEAVING LYMPNE : Sir Philip Sassoon in the " Hart "("Kestrel"), by which he flew back to London from Lympne, bidding goodbye to Com. C. T. Deacon, theofficer in charge of Lympne aerodrome. (FLIGHT Pholo.j jointly by the British and French Air Ministries, andshould result in easing the work of the Croydon and St. Inglevert wireless stations very considerably. At thepresent time when Lympne wishes to report to St. Inglevert that a certain machine without wireless has circled, inti-mating that the pilot is flying across the Channel,' it is necessary to ring up Croydon by land line and for themessage to be sent all the way back to St. Inglevert, from thence by wireless. Now, the operator at Lympne itselfwill instantaneously be able to tell St. Inglevert when such machines leave. This means that if necessary allmatters affecting ground organisation and machines which arr not fitted with wireless, can, if the normal wirelessservice is busy, be sent from Croydon to Lympne by land line and thence to St. Inglevert by Micro-Kay, thusleaving the wireless services of both airports free to deal with the control of air traffic which is fitted with wireless. A further advantage of the system will be the speedwith which meteorological reports'can be sent between the French and English coasts. Owing to the present con-gestion, messages may often take a considerable time during which conditions may change very much indeed. Thenew service should obviate this difficulty and assist pilots greatly. The Micro-Kay is a revolutionary system operating onthe shortest wavelength which has ever been used com- mercially, that is, one of only 17 centimetres. Theaerials are less than an inch long and radiate less power than is required to light a pocket flash lamp—the wave-lengths normally used for aerial and route traffic messages are 900 metres and 1,380 metres. The whole equipment at Lympne was erected by StandardTelephones & Cables, Ltd., and that at St. Inglevert by the associated French company, Le Materiel Telephoniqueof Paris. The wavelengths are slightly staggered, 17 centimetres being used for transmission and 17^ centimetresfor reception. This enables two-way speech or simul- taneous working by teleprinter and telephones. The Micro-Rays are concentrated by reflectors into a line pencil of rays direct towards the receiving station. They travel ina straight line and can only be picked up by a receiver lying directly in their path. Their nature obviates inter-ference of every sort, including atmospherics, and produces a signal of unvarying strength, thus enabling the teleprinterto be used successfully for the first time by wireless. The reflectors at Lympne are erected on the roof of the southernhangar, and are placed in an optically clear line with those on steel towers at St. Inglevert 35 miles away. Passing of an oldfriend— THE aeronautical world in general, and the technicalfraternity in particular, will learn with deep regret that, with the end of 1933, the German journal Zeitschrift fiirFlugtechnik und Motorluftschiffahrt ceased publication. One of the earliest of technical aviation journals, the" Z.F.M.," as it was usually called, gradually achieved an unchallenged position among the more highly technicalpublications, dealing as it did mainly with the theoretical aspects of aeronautics. As the official organ of the Wissen-schaftliche Gesellschaft fur Luftfahrt E.V. (commonly known as the " W.G.L."), the old " Z.F.M." occu-pies a position somewhat analogous to that of the Journal of the Royal Aeronautical Society in thiscountry, but differed from it in being wider in its scope and carrying news of a technical or semi-technical naturefrom all over the world. The official organ of the " W.G.L." will in future be Luftfahrzeugbau und Luft-fahrt nebst Randgebieten. This journal, which has just entered upon its second year of publication, is edited byRegierungsrat Dipl.-Ing. Baatz. The January, 1934, number, is a small eight-page paper, comparable in no waywith the old " Z.F.M." and carrying no advertisements whatever. —and the appearance of a new one No. 1, Vol. I, of the Journal of the AeronauticalSciences has iust reached us. This is the American "opposite number" to our Journal of the Royal Aero-nautical Society, which it somewhat resembles in the colour and type face of its cover. The American publica-tion is, however, somewhat larger (8 in. x 10£ in.), and dirlers from our Journal in that the contents list showsmainlv contributed articles and not, as in the British pub- lication, papers read before the institution. Among thecontributors to the first number are our own Mr. A. Fage and Mr. A. J. Sutton Pippard. As the official journal ofthe Institute of the Aeronautical Sciences, Inc., the new publication was expected to be of a fairly highly technicalnature, and this is actually the case. The Institute of the Aeronautical Sciences, which is the American equiva-lent to our R.oyal Aeronautical Society, was founded about a year ago. Its first president is Mr. J. C. Hunsaker,who has acted as editor of the first issue of the Journal, and the Secretary of the Institute is Mr. Lester D. Gardner.The price of the Journal to British subscribers is three dollars per annum, 75 cents for a single copy. Corre-spondence should be addressed to the editorial offices of the Journal of the Aeronautical Sciences, Inc., 5431,R.C.A. Buildings, Rockefeller Center, New York City, N.Y. Reorganising German air press As recorded above, the famous German scientificaeronautical journal " Z.F.M." stopped publication at the end of last year. It appears that there has been a re-shuffling of German aeronautical journals generally, as the oaper Luftwacht has, with the beginning of this year, splititself into three separate publications: Luftwissen, Luft- wchr, and Luftwelt. In an introduction to the new pub-lications it is stated that the journals appear at the wish of the German Air Ministry, although it must not be takenthat the views expressed are necessarily those of the Minis- try. The same phrase, or at least one very similar, isused whenever a British Air Ministry official reads a paper to the Royal Aeronautical Society, and the significance ofit in this case may be much about the same. Of the three new journals, Luftwissen, which will appear on the 15th ofeach month, deals with the scientific and technical side, taking to some extent the place of the late lamented" Z.F.M." Luftwehr will be published on the first of each month, and deals with military aviation the world over.Luftwelt is a fortnightly journal, published on the 8th and 22nd of each month, and deals with civil and commercialaviation. It is claimed that the rationalisation effected will avoid much overlapping of journals previously pub-lished. We hope our old friend Oskar Ursinus will not have Flugsport " axed." He has ever ploughed a lonelyfurrow, and one can imagine that he may be faced with serious difficulties under the present rdgime in Germany.
