And now a beer meter. Washington, D.C., May 1. To aid Uncle Same in collecting the tax on the millions of barrels of beer brewed in this country every year, the National Bureau of Standards has designed a master beer meter for use of the alcohol unit of the Bureau of Internal Revenue, U.S. Treasury. Government inspectors employ this master meter in checking the accuracy of the brewery beer meter to determine the volume of beer brewed. In the photograph the large tank receives the liquid [after passing] thru the meter where it is weighed to get [the] true volume. Carl F. Stoneburner is reading [...]

Final check, weather device. Washington, D.C., Sept. 13. L.L. Stockman, also of the Bureau of Standards, Radium Division, uses a wave meter to check the radiometeorograph before attaching it to the parachute and the balloon. When the inflated bag breaks, which it usually does after several hours flying, the instrument is parachuted to the ground. Many times the instrument is found and returned to the bureau. The radiometeorograph contains two radio tubes, a miniature dry cell battery and devices which record and send the weather signals which, in turn, are recorded on a chronograph in Dr. Astin's bood [?] radio room.

Government regulation needed to insure Detroit steady supply of milk, Monopoly Committee told. Washington, D.C., May 2. Kenneth L. Vardon, President of the United Dairy Workers Union of Detroit, today told the Temporary National Economic Committee that some form of government regulation must be imposed to insure Detroit a steady supply of milk at a just price to the consumer, the distributor, and the farmer.

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
