JANUARY 28, 1937. FLIGHT. 89 I), soutter has built as a- hobby, and which we induced him to demonstrate (doubtless invitin'g the grave displeasure of Mr. Gillman, for it formed such a grand counter-attraction). It is the smallest and most perfectly finished miniature engine we have ever seen. But that is by the way. And so is Mr. Desoutter's story of the burglars who broke into his works. With designs on the safe, they tried to connect up a Pesoutter pneumatic drill with the elec tric supply. ... * * * T HE upper half of the light spectrum plays havoc with the colours both of the physiognomy and the old school tie, and visitors to the Edison' Swan Electric Company's stand suffered a terrifying metamorphosis. This stand was lit by two high-power mercury vapour lamps, and 'it was in the value quickly and sweetly along their guide rails, stopping at the command of, auto matic cut-out switches. The doors retain a slight zig-zag surface when fully closed, this acting as a wind-break which deflects pressure on to the upright post between each leaf. * * £ W E believe we are right in assuming that the firm of En-Tout-Cas owe their picturesque title to their activities as pioneers of hard tennis courts. "In all cases" or "At all events" —translate it as you will—the name is equally descriptive of their wider activi ties nowadays, which cover every form of aerodrome construction and building. Laying-out, reconditioning, draining, erection of buildings—they are prepared, it seems, to tackle any proposition. Extensions at Filton and Heston, com plete constructional works at Ytitesbury, and operation of, these that we were par ticularly interested. Since these lamps are claimed to be over one hundred per cent, more efficient, light for wattage, than the normal filament type, this minor dis advantage can be forgotten when it comes to the business of lighting airport approaches or large workshops. At present, such lamps—which are virtually arc lamps in which the arc is formed of incandescent mercury vapour—cannot he satisfactorily made in very small sizes, but experiments are going on, and within a few months Ediswans will probably have miniature mercury lamps on the market. * * # jV/TANY Exhibition visitors must have -1 had their memories stirred, pain- "illy or otherwise, by the name '' Edu cational Supply Association " over stand 22.
