MATERIAL FOR FACING SERVO DISCS. -------------------------------- Hs.{Lord Ernest Hives - Chair} is of the opinion that "Halo" gives rather more consistent results for this particular service than "Ferodo". The actual duty called for is not great, but apparently within the limits of Servo requirements "Halo" is preferred. The D.O. should alter the material for the facings on the Servo from Ferodo to "Halo" accordingly. BY.{R.W. Bailey - Chief Engineer} | ||
