| To EH. & EFC. {E. Fowler Clarke - Electrical Engineer} from Oy. 2. Oy2/B30:6:17. (b) Whether the cam was well finished. (c) What was the pressure on the platinum points. The grey fibre used should be compressed in small squares of about .75 in.² area. These are put into the hydraulic press two at a time and are compressed with the maximum load, which makes them about 75% of their original thickness. They gradually recover about another 5%, giving 20% final contraction. Oy. M. {Mr Moon / Mr Moore} Olley. | ||
