THE performance put up by the Supermarine Amphibian at Martlesham and Felixstowe was in many respects a note- worthy one. At the end of the 24-hour mooring test it got away within the 60 minutes allowed for starting up and getting under way, the Rolls-Royce engine starting on the second turn of the handle. We understand that it was the only amphibian to complete the whole of the tests without any alteration or adjustment having to be made. ... - IN these days of soaring prices it is interesting to hear of a process that will effectively repair scored cylinders at a minimum cost. This is today being achieved by the Barimar Metallurgical Process. In pre-War days the only reliable method of rendering scored cylinders thoroughly efficient was to weld up the scores, regrind bores and then fit new pistons complete. Such an operation was a costly one and the work took some four to six weeks to complete. Today, many cylinders scored in this way are being successfully treated by this newest invention, for a figure which is only about 10 to 20 per cent, of the cost of the old method, and the work is finished in about two days. A further point, and one of paramount importance, is that when cylinders are repaired by this process, they do not have to be. welded or reground, and th"ey do not require new pistons. DR. A. P. THURSTON, D.SC, F.R.Ae.S., etc., whose name is well known in connection with aviation matters, has now estab- lished himself at Bank Chambers, 329. High Holborn, W.C. 1, where he is specialising in the development of inventions and work of such nature. IT is interesting to learn that nine of the aeroplanes engaged in commercial services between England and the Continent have already been equipped with the Marconi wire- less telephone ; and that others are now being similarly fitted. ONE of the outstanding features of the Commercial Vehicle Show to those interested in the electrical equipment side of the industry was the universal manner in which the manufactures of the great Acton House predominated. No leas than 50 lorries, buses, and commercial cars were C.A.V. equipped, while all other British makes total only 17 amongst them. H H H H A Rumour Scotched DAME RUMOUR seized on the fact that the Martinsyde works closed down last week for stocktaking to start a pretty little story indicating that the closing was permanent. Messrs. Martinsyde, however, soon corrected this and made it clear that the temporary closing did not in any way affect their business, as they were carrying on as usual.Commercial Consistency ONE of the Airco 16 machines of the Air Transport and Travel Line, G-EAQS, put in a very consistent six-days' work between Croydon-Paris-Croydon last week. From the 17th to the 22nd inst. she made three " oat" and four " home " trips without missing a day's flying. Incidentally, she made the fastest time of the week for the journey each way, doing the Paris-Croydon trip in I hr. 50 mins., and the Croydon-Paris in 2 hrs. Berlin-London in 8 hours ONE of the fast machines of the Handley Paefe service on October 25 made the first trip between Berlin and London within 8 hours. Leaving Berlin at 9.15 a.m., a stop for lunch was made at Cologne at 12.25 p.m. Restarting at 2.10 p.m., the trip to Cricklewood was made in exactly three hours, the machine landing safely at 5.10 p.m. The actual flying time for the trip was 6 hours 10 minutes. A Week at Le Bourget DURING the week from October 10 to October 17, 143 aeroplanes left or landed at the Le Bourget Aerodrome, near Paris, carryine; an aggregate of 315 passengers, 33 tons of goods, and 3 cwt. 66 lb. of mails. Air Fleet for the Reds ? A REPORT from Reval states that according to the paper Pravda, the Bolsheviks are establishing a Red air fleet, and are constructing a large number of aeroplanes of the latest type. Many youne; men are being trained as aviators.Cossack General Escapes by Air BY way of concluding a wireless message from Chita, Trans-Baikalia, Siberia, to the effect that " partisans" have occupied the city and that a temporary Assembly has taken over full power, it is stated that General Semenoff, the Cossack leader, who recently acknowledged the supremacy of Wrangel, escaped in an aeroplane.
