We attach herewith copy of a letter from the Continental Fibre Co. of Newark, Delaware, referring to Bakelite-Dilecto and Continental-Bakelite, impregnated materials of which the base is paper in the first case, and linen or cotton duck in the second. Samples are being forwarded to you. 2. From observations of electrical fittings for automobiles and aero engines in this country, sheets of this material are now used practically without exception on all classes of high-grade automobile fittings to replace mica and micenite, and also to replace hard rubber and fibre. The material can be stamped under a press, just like sheet metal. Mr. Clark will be able to tell us how the figures for puncture compare with micanite and fibre or hard rubber. 3. Bakelite in some form or other is used on most of the high tension magneto distributors, etc., in this country, though on the cheaper class of fittings, such as the Remy Ignition, Condensite is still used. 4. The use of Bakelised Linen for gears has been standardised by most of the magneto makers, for example, Splitdorf, Eisemann and Sims, although it is not yet used by the Ericsson people, who make the Berling magneto, of which samples have been sent you. The bakelite sheets are used for driving pinion on the armature spindle. | ||
