| HS{Lord Ernest Hives - Chair}/EST. ) FROM R.{Sir Henry Royce} BH ) C. TO SC. WOR.{Arthur Wormald - General Works Manager} FN. ORIGINAL WSP re. VIBRATOR CONTROL. R3/W19.11.32. X6092 It has occurred to me that this might require to be carried on the car a certain way up owing to the rather delicate suspending copper springs. I also wondered whether, being hermetically sealed, it might be a practice of the makers to send these out filled with an inert gas so as to prevent the oxidation of the points. This is not much of our business but it would be interesting to know, and it might be an idea worthy of a patent. Unfortunately it cannot be utilised in the contact chamber of the make and break and high tension, because in that case it is mechanically driven, and cannot be closely sealed. I give the idea however out of pure interest, and leave you to find out whether it is worth anything. We hope with the vibrator control that the dynamo output can be raised with the same degree of heat, and that the report will be that owing to the absence of the 3rd. brush the commutator remains in better condition. We however take some pains to sub-divide the commutator into an unusually large number of sections so as to have little or no trouble with the brushes. so the difference may be difficult to prove. re sparking. for R.{Sir Henry Royce} | ||
