| To R.{Sir Henry Royce} from EFC. c. BJ. E.{Mr Elliott - Chief Engineer} c. By.{R.W. Bailey - Chief Engineer} Eor. X865D EFC/T4.1.28. SEQUENCE STARTER SIMPLIFIED SCHEME. X7655B We have noted the remarks contained in your RL/M23.12.27 and will ask for the question of the patent situation to be looked into. Referring to your RL/M29.12.27 we have a satisfactory 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 Let.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. | ||
