Rolls Royce Ltd., D E R B Y. WST Dear Sirs, Re CONSTANT VOLTAGE REGULATOR. We must apologise for not writing you earlier on this matter. We have, however, taken it up with the works, and they insist on having further information so that they are able to send us a suitable regulator for you. On account of our regulator having 4 contact poles and consequently 4 respective resistance packets, it is essential that we know the field current curve over the speed range at load and on open circuit. As soon as you will be good enough to send us these particulars, we shall then forward them to our works, so that they can prepare an instrument and let you have it for test. Yours faithfully, For SCINTILLA LIMITED MANAGING DIRECTOR. A Revolution in Ignition. "VERTEX" Instantaneous starting in coldest weather with VERTEX Type VM4 for 4-cylinder engines. Regular sparking at low and high speeds with VERTEX Type VM6 for 6-cylinder engines. The advantages of battery and magneto ignition in one unit with VERTEX Type VM8 for 8-cylinder engines. | ||
