| R.H. 235A (100 T) S.H. 798. 10-12-30: C 2547 X2572 To R.{Sir Henry Royce} from EFC. C. GW C. PH. C. WOR.{Arthur Wormald - General Works Manager} C. EF. EPC2/T1.18.21. X. 3656 - IRIDIO-PLATINUM CONTACT POINTS WITH A MUCH SMALLER AMOUNT OF PLATINUM THAN STANDARD. The dia. of the welded on platinum points we now notice to be a little less than our standard platinum point diameter, and as it would not seem advisable to standardise these with the reduced diameter, we are taking up the question of increasing the dia., with Messrs. Reynolds. Regarding increasing the capacity of the condenser, practically no increase in the capacity can be secured in the present box. Therefore, we are going into the matter as to what extent the depth of the box can be reasonably increased without fouling the bonnet. EFC. | ||
