LIGHT BEAM ADDED TO AIR STATION. – Revolving Light, Three Million Candlepower On 51-Foot Tower Put In Just Recently.
The new revolving beam tower at the remote control station of the radio beam transmission station is now complete and will soon be equipped with a 1000-watt lamp and will revolve a finger of 3,000,000 candle power of reflected light from sundown to sunrise.
The tower which is topped by the light beacon is 51 feet high and is of steel. It is automatically regulated to turn on and off by a sauter clock in the remote control station building. It is lined up with the sound beam beacon and revolves the same course and should be visible a good many miles. With the revolving of the semi-spherical reflector at the interval when the light at 180 degrees is invisible from an angle of obstruction light at the abse of the reflector automatically turns on showing ambient aircraft the on-course signal visibly, just as the sound beam shows it orally.
The lamp, set on the platform on top of the tower, is regulated and should need no further attention apart from occasional inspection. The platform is accessible by a trapdoor on its base, which is padlocked between inspections. The lamp is even equipped with a heater so that even very low temperatures cannot interfere with the daily turning on and off.
Cement piers 6 feet deep form the base of the tower, to which the steel is bolted. The anemometer for recording velocity and direction of the wind has been put on the top platform. There is also a mounting for the wind cone close to the top.
The biggest job done recently in equipping the station was the installation of the sauter clock to register sidereal time, by which automatic adjustment of the various machines is regulated. Sidereal time is star time, as against sun time which does not record the day to day differences in duration of light.
Interesting information was available as to the coloring of the buildings at the station. They are white trimmed with international orange, a shade which was discovered after considerable scientific research to show up best under every known prevailing weather condition, green of spring and summer, white of snow, and red and orange of foliage in fall. It is used universally for airline buildings the world over.
A fault in the shade of the aerial poles on either side of the station will have to be corrected as they are distinctly off [inter] national orange. The poles are cedar 60 feet high, 24 inches at the base and tapering to 18 inches at the top, and were supplied by M. Dumont of Galloway. They support the wires for plane to ground receiving and transmission, and have obstruction lights on top which are also regulated by the sauter clock.
The new station house is completed and some of the equipment installed but the staff are awaiting the arrival of the requisite furniture before moving in. The building is heated with a central furnace. The sauter clock is located here. The wiring is completed also.
The blue and silver plane which was in for a few days the week before last was a C.M. & S. plane from Creston which dropped in to change its landing gear from wheels to skiis. The thaw which happened at that time necessitated the crew remaining until the snow was more suitable for taking off. At the airport they report that the experimental flights with skiis were successful with the only disadvantage the lack of brakes on landing.
