| b 103 To EJJ. Rm{William Robotham - Chief Engineer}/RC.{R. Childs}11/JH./7.2.39. Will you please obtain for us from the Westinghouse Brake and Signal Co.Ltd., 82, York Road, Kings Cross, LONDON 1 rectifier, Style R.G.C.8.A. (for use on AC 200/250 volts 40/60 cycles), Max., load: three 12 volt battery at 10 amps. In order to complete life tests on various types of batteries it is necessary to charge during the night and discharge during the day. Up to the present we have had to rely on the night shift of the aero section switching on the generator at night. This has proved unreliable causing numerous breakdowns on our life tests). A rectifier will not require any attention. Rm{William Robotham - Chief Engineer}/RC.{R. Childs} | ||
