| Contd. -2- EFC1/T15.12.20. In this cut-out the contact is not broken quite so definitely as in the Bleriot Phi cut-out, although it is made quite definitely. Examination of the figures will show that the cut-out is set late according to our specification, also that the range between hot and cold is very considerable. X.1005 We have also made tests on the Rotax cut-out and the Rotax cut-out in conjunction with a Rotax dynamo, but as this cut-out is a bulky piece of apparatus, and has no particularly good points, we are not reporting these or sending this instrument to Mr. Royce for examination.
