Osborne Reynolds identified the phenomenon of cavitation as early as 1873. By the ton of the century it had been called by its present name by R. E. Froude, the director of the British Admiralty Ship Model Testing Laboratories. 

It is recommended that any higher-viscosity product such as residual oil or heavy distillate fuel be evaluated for changes in low-temperature handling properties over time. Testing for reversion in pour point by the Shell Amsterdam Reversion Test or the British Admiralty Pour Point Reversion Test are recommended. Also, viscosity increase versus temperature decrease determinations are recommended for products stored at low temperatures for extended periods of time. 

This procedure can be utilized to determine whether heavy fuel wax crystal modifiers will lose their performance properties after long-term storage at fluctuating temperatures. Daily heating and overnight cooling may interfere with the ability of some wax crystal modifiers to maintain their performance properties in some residual oils and crude oils. This loss of performance is frequently termed pour point reversion. The British Admiralty Pour Point Test can be utilized to help predict these reversion tendencies. 

Identify whether the oil treated with a wax crystal modifier will revert in pour point by testing utilizing either the British Admiralty Pour Point Reversion Test or the Shell Amsterdam Reversion Test. 

In 1795 the British admiralty finally mandated a ration of concentrated lime or lemon juice for all British sailors (hence the name limeys ). Scurvy continued to be a problem in some other parts of the world until 1932, when Hungarian scientist Albert Szent-Gyorgyi, and W. A. Waugh and C. G. King at the University of Pittsburgh, isolated and synthesized ascorbic acid. 

Two Glasgow women chemists were employed directly by the Admiralty as analytical chemists. Ada Hitchens (see Chap. 6) was assigned to work in the Admiralty Steel Analysis Laboratories, while Ruth Pirret (see Chap. 7) became a wartime researcher on marine engine boiler corrosion for the British Admiralty.42... 

On the recommendation of the Camoufltige Research Center at P2astmttn Kodak, the US Navy s Buretiu of Construction tind Keptiir finally adopted a dazzle painting system which was verv similar to that of the British Admiralty. 

Francis Harry Compton Crick was born on 8 June 1916 in Northampton, England. He studied physics at University College, London, where he obtained a BSc in 1937. He then started his PhD in physics, which was interrupted in 1939 by the outbreak of World War II. Crick worked as a scientist for the British Admiralty until he left in 1947 to study biology in Cambridge, where he worked at the Strangeways Research Laboratory. 

So it came about, writes Weizmann, that one day in March [1915], I returned firom a visit to Paris to find waiting for me a summons to the British Admiralty. The Admiralty, of which Winston Churchill, at forty-one exactly Weizmann s age, was First Lord, faced a severe shortage of acetone. That acrid solvent was a crucial ingredient in the manufacture of... 

Leo Szilard s work at the University of Rochester confirmed that no neutrons came out when indium was irradiated. On December 21, as Hahn and Meitner exchanged their excited letters, Szilard advised the British Admiralty by letter ... 

In New York that day Szilard dragged himself to the nearest Western Union office and cabled the British Admiralty ... 

So it... British Admiralty ibid., p. 172. Weizmann writes 1916, but this is clearly a slip of memory. Cf. Stein (1961), p. 118. Churchill was no longer First Lord in 1916. 

Szilard showed me copies of some of the patent applications which he made in 1934 and 1935. (I may remark that he presented his patents to the British Admiralty, according to a copy of a letter from this authority to Szilard.) These patent applications contain rather detailed plans and calculations and many of these calculations were very useful when the plans later reached a more acute stage. One of his applications contains the following passage ... 

English sailors have been called "limeys" because the British admiralty In 1835 ordered a daily ration of lime juice to prevent scurvy, the vitamin C deficiency disease. The message did not hit home in America, however, where scurvy was common among troops during the Civil War. 

Most countries have a national datum level, which is often approximately equal to the MSL (for example Ordnance Datum in the UK). Chart Datum conversely, as used by the British Admiralty, represents the Lowest Astronomical Tide, which varies significantly from one place to another. 

A number of companies have been developing this battery including Gould and Electrofuel, and large sized batteries are expected to be demonstrated by 1990. In addition to Argonne, the British Admiralty laboratories has been developing this battery for submarine applications while other potential applications include electric vehicles and load levelling.
