| EFC {E. Fowler Clarke - Electrical Engineer} 1/T29.3.26. -8- Contd. that a variation of +- .004" in the platinum point gap, would cause a variation of perhaps +- 10° in the instant of make, the actual instant of which within these limits is not of serious consequence, if it is, as on our suggestions, already taking place in a time region where the rate of change of flux is for the moment small.
