To CY. from EFC. {E. Fowler Clarke - Electrical Engineer} X4333 EFC {E. Fowler Clarke - Electrical Engineer} 2/T14.8.22. X. 3513 - BAKELITE COMMUTATORS. X4333 Would you kindly let me know - (1) Whether moulded bakelite commutators are successfully made in U.S.A. for chassis dynamos, as well as starter motors. (2) If this is the case, whether the standard bakelite powder is used, which powder we are able to obtain in this country from the Damard Lacquer Company, or whether a special grade of bakelite powder, which gives a stronger result but is not so freely moulded, is used for this purpose, and if so, how we could obtain some of this special grade for experimental commutator purposes.
