Blind landing now possible. Washington D.C. It is now possible to make blind landings which has been one of the biggest difficulties to aviation. It is this single instrument located above the panel in the center directs him to the ground in a curved track and also in a straight line so as to hit the runway that is chosen for the landing. By watching the above instrument the pilot can direct his plane to the ground and determine whether he is to the right or left or above or below the beam that is transmitted. In tests that have been made the pilot has been able to land repeatedly within a few yards of the same spot

New Mosquito Boat gets a tryout. Washington, D.C., June 19. The PT-9, first of the new 'Mosquito Boats' to be delivered to the U.S. Navy under the President's $15,000,000 experimental small craft program had a preview for the press today. This is the same type of boat that the government is in process of releasing to the British Navy, causing great unrest and indignation in Capitol circles. Eight other boats will be based at the naval operating base, Norfolk, Virginia, to undergo severe seagoing tests. The squadron will be known as the Mosquito Fleet and the insignia which was designed by Walt Disney consists of a mosquito riding on the top of a high speed torpedo. Shown in the picture is Lieutenant Earl S. Caldwell, USN, Commander of the squadron

New 'Mosquito Boat' ready for action. Washington, D.C., June 19. The PT-9, first of the American Motor Torpedo Boats to be delivered to the U.S. Navy under the President's $15,000,000 experimental small craft program had a preview showing for the press today. The 'Mosquito Boat' and eight other ones will be based at the naval operating base, Norfolk, Virginia, where they will undergo service tests under various sea conditions to determine their capabilities and limitations. This is the same type of boat that the government is in the process of releasing to the British Navy. Chairman David L. Walsh of the Senate Naval Affairs Committee expressed indignation over the Navy's action in this respect in view of the fact that this government is trying to build up its own sea power

National Archives. Washington, D.C., Nov. 22. In the powerful press, the sheets of acetate, under heat and pressure 'melt' into the pores of the paper and adhere to each other as well. One additional advantage of this process is that, after being pressed with the sheets of cellulose acetate, the paper is thinner and takes up less room than it did originally. The result is a sheet of paper and acetate which comes off the polished metal plates as a single sheet. Tests for the aging of this material made by the Bureau of Standards in Washington have shown that this treatment of the paper, called laminating is as permanent as it is possible to make any record of paper

Bureau of Standards breaks up plates for a reason. Washington, D.C., May 23. Just about everything manufactured in this country is made the subject of tests in the Bureau of Standards here. Even the dinner plates used in restaurants go through a series of tests in order that the government may known just how long it can expect them to last in usage. R.F. Galler, Chief of the White Wear section, is here operating an impact machine to determine the amount of force necessary to cause those germ-concealing chips in a plate. Previous in this test, the plate is ground with porcelain to find out how long a plate may be handled before it loses its gleam, and samples are heated to find out how much heat is necessary to cause cracks to appear in the glazing
