Rolls, Royce Limited, Nightingale Road, Derby. [STAMP] RECEIVED 31 MAY 1917 Dear Sirs, TUNGSTEN CONTACTS. In further reference to your letter of the 1st instant, our Works write us that it seems that the spark of a Magneto developes a much higher heat and causes a disintegration of the Tungsten. They are working on a new composition which ought to do away with this condition, and we will let you know immediately they have succeeded in proceeding the new compound for a Magneto service. In the meantime, We remain, Yours faithfully, THE L.P.S. ELECTRICAL CO. [Signature] | ||
