X.1402 - CHASSIS DYNAMO EXTERNAL REGULATORS.

We have, with the assistance of Mr. Walker, looked into the question of Patents in connection with the above, and have obtained a number of complete Specifications, short descriptions of which are given on the accompanying sheet.

Those marked with a cross are at present in force.

We have looked over Specifications Nos. 9426 and 149611 and now send these along for your perusal. The other specifications will follow in due course, when we have been able to look these through.
