| To EY/RD. from EEC. x5670 EFC1/T1.6.27. BRUSH SPRING PRESSURES. Answering your EY/RD6/ML4.6.27, we see no objection to having a common spring of the intermediate poundage suggested, as owing to the adjustment that can be made, it would appear that we should be able to get our specified pressures on both the main and control brush, and also to get a suitable pressure (unspecified) in the case of the motor.
