Dear Sir:- TUNGSTEN CONTACT POINTS. Last winter two sets of Tungsten Contact Points were taken by me to England for experiments at Derby. The Independent Lamp & Wire Company of America now request that they have a report on the tests of these Tungsten points. I was only able to inform them that we were testing the points, since on July 12th. I received from Mr. E.F. Clarke a copy of a letter from him to Mr. Royce referring to the working of these contact points. At your earliest convenience I would like to have a report on the behaviour of these points to refer to the maker. Very truly yours, ROLLS-ROYCE OF AMERICA, Inc. Per (Sgd) M.Olley. MO/C. CC. Messrs. Belknap. Nadin. Keim. | ||
