| X 4430 To RHC. {R. H. Coverley - Production Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} c. Mr. Brock. c. Ey. EFC {E. Fowler Clarke - Electrical Engineer} 4/T20.7.22. X.4430 - GOSHAWK BATTERY IGNITION CONDENSERS. The provisionally fixed capacity limits for the Goshawk condenser are .275 to .325 mf. For the purpose of finding out the effects of different capacities on our experimental ignition rig, which we are shortly expecting to receive, five condensers of approximate capacities .250, .275 .300, .325 and .350 mf. should be supplied to us. This will enable us to fix with certainty suitable capacity limits. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
