| To R.{Sir Henry Royce} from EFC. c. to CJ. ORIGINAL EFC3/T9.6.23. X.4589 - B.L.I.C. VOLTAGE REGULATOR. We yesterday received a visit from two representatives of the B.L.I.C. (British Lighting & Ignition Company) and a certain amount of discussion took place in regard to their new rotating magnet magneto utilising Cobalt steel magnets. A six-cylinder model of this is not at present in readiness, but they hope to let us have some information about this later on. They are, however, developing a system of voltage control, more particularly applicable to chassis generators already of the third brush variety, and deeming this of sufficient interest to us in present circumstances, we are arranging at their request to let them have a 20 H.P. dynamo to which they can adapt their scheme of external regulator, and pass the whole back to us for experimental test. The regulation is effected by the utilisation of a set of six small cells which constitute an inert back E.M.F. i.e. a battery which will absorb energy but which is practically incapable of being more than temporarily polarised. The actual battery consists of cells in which steel plates are immersed in alkaline solution. The regulator, as adapted to third brush controlled machines is shown in the simple diagram, R being a resistance of suitable value. Further remarks re the working of the system at the moment seem unnecessary as the idea appears to be comparatively simple. (Diagram attached) EFC. | ||
