| To R.{Sir Henry Royce} from EFC. c. BJ. E.{Mr Elliott - Chief Engineer} c. By.{R.W. Bailey - Chief Engineer} Wor.{Arthur Wormald - General Works Manager} X765573 EFCL/T4.1.28. SEQUENCE STARTER SIMPLIFIED SCHEME. X8651 We have noted the remarks contained in your HL/M23.12.27 and will ask for the question of the patent situation to be looked into. Referring to your HL/M29.12.27 we have a satis-factory design of a simple two-point switch which we were using with the sequence starter before the necessity of the duplex switch was arrived at. This design is to your LeC.1904 and was satisfactory in itself. The 2B scheme with sharp engaging corners, rounded dis-engaging corners, and 5° spiral, for EAC.1. chassis 9-EX is now fully instructed to the Experimental Shop. EFC. LEC.1904 sent to R.{Sir Henry Royce} 5-1-28 | ||
