REMOVES METAL PARTICLES FROM EYES WITH RING MAGNET DESIGNED IN ENGLAND
ONE of the latest developments in the field of medical science is the ring magnet. It is proving of great value in removing pieces of metal from the eye after an accident. Workers in various industries often suffer from flying pieces of metal striking the eye. To remove such small particles is often a delicate operation whose pain is greatly lessened through the use of this ingenious device.
NEW MAIL PLANE HIDES WHEELS AS IT RISES (Dec, 1930)
That sure is an interesting way to refuel a plane…
NEW MAIL PLANE HIDES WHEELS AS IT RISES
When the newest of the mail planes leaves the ground, the landing wheels swing backward and tuck themselves away in the lower side of the wing. A study in streamlining, the 158-mile-an-hour “Boeing Monomail” is shaped so that its speedy passage through the sky meets with the least possible air resistance. Recently the all-metal craft was placed in regular service on the air mail route between Chicago and San Francisco.
A glance at this low-wing monoplane’s lines shows how far airplane designers have progressed since the “bird-cage” biplanes, crisscrossed with struts and wire braces, of fifteen years ago. The “Mono-mail’s” fuselage tapers like a cigar, and is broken only by a low windshield for the pilot. Around the motor a newly-developed type of cowling further reduces wind resistance.
