Out of the Labs

P: Dark red veterinary petrolatum took first place with scientists as a sunburn lotion. Called in by the Army to test suntan preparations for marooned sailors and airmen, G.E. tested 13, turned thumbs down on some of the more highly advertised, water-soluble products. Also recommended: phenyl salicylate.

P: Three new synthetic engine lubricants, all from different sources (silicones, natural gas and other organic chemicals) were previewed last week. The makers' claim: all three have a fairly constant rate of flow in boiling heat or freezing cold; none forms sludge, carbon or varnish on cylinder heads and spark plugs. California's Union Oil Co. joined the chorus with a motor oil called "New Triton," which is long-wearing, noncorrosive, sludge-free.

P: A daytime star-sighter, to put celestial navigation on a 24-hour basis, was announced by the A.A.F. Board at Orlando, Fla. An improvement on solar navigation (which requires morning, noon and afternoon sights, plus computations), the new device enables a pilot to choose the stars he wishes to use, plot his position any time of day.
