Contd. -2- CK{Mr Clark}5/T10.2.20. and the Prince of Wales' Car, in regard to cutting in speed without investigations, as it may be due to a number of causes. We have not found on the bench any great variation between the cutting in speeds of various E.575 dynamos. It is, of course, possible that the cut-outs in the two cases are differently set so that current is picked up in the one case later on in the curve than in the other. Regarding the second paragraph on page 2 of your note, we will carry on with tests on temperature rise of dynamo and cutout so as to thoroughly investigate this matter. Ck.{Mr Clark} | ||
