| Contd. (Extract) X765513 -2- To R.{Sir Henry Royce} etc. EFC6/T6.9.27. X.7625A We have each of the two items (2) and (3) associated with a No.1 item on experimental chassis. Further proposals for which we have not received working designs from W.W. are :- (4) Combined switch with mechanical interlock between the armatures (relay switch cannot be on actuator contact while main switch is on). (5) No. 2B motor (outward sliding armature). For this item our preliminary suggested calculations were sent to you, but we have not yet received from WW. any further design. EFC. | ||
