| X. 4430. To By {R.W. Bailey - Chief Engineer} /C. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 2/T2.3.23. X.4430 - GOSHAWK CONDENSER In answer to your note with reference to the attached letter, electrically the reduced thickness of the foil is of no consequence. Therefore, we should, if it is possible mechanically in building up the condensers, use the foil single. If difficulty is experienced in building up with this thickness, then it would be necessary to insist on the .005" material. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
