| Contd. -11- EFC/T12.6.23. Some such system is considered highly desirable on R.R. chassis. It overcomes difficulties such as fusing difficulties, running with battery disconnected, etc. which we have at present, and we are of the opinion that it is quite possible for a really satisfactory regulator to be designed on sound lines, and having such a satisfactory mechanical design that we could arrange the proportion of the windings to bring about the result required. Except in the case of the R.{Sir Henry Royce} Bosch we do not consider this has been done, but that the reputed satisfaction given by such regulators as the Westinghouse and Bijur is very largely due to the ease with which these units can be changed at Service Stations when they become erratic, our own experience with such units having been that they are almost certain to become erratic after running for a short while. It is true that the R.{Sir Henry Royce} Bosch has not had an opportunity of running on the chassis, but we have little doubt of the result, and we know that the Westinghouse and 6 volt Bijur have been distinctly erratic on the bench test. The Scintilla dynamo produces a rather bad hum when on load, particularly so about 1100 r.p.m. and again at 3600 r.p.m. Photostat sheet & Blueprint attached. EFC. | ||
