| Hl 6099. E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. c. to By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Wst.1/MA.17.12.34. R.R. DYNAMO CUTOUT. An improvement of the design of this cutout is now imperative as not only is the volt drop across the switch excessive but the temperature rise across the contacts is excessive due to the heavier current now being taken by our dynamo system. We should be glad therefore if some design action can be taken on the lines as suggested in Hs{Lord Ernest Hives - Chair}/Wst.2/MA.26.11.34. Hs{Lord Ernest Hives - Chair}/Wst. | ||
