TY - JOUR AB - THE purpose of this article is to describe a useful variable velocity‐ratio unit suitable for inclusion in flying‐control circuits of aeroplanes, and to provide sufficient of a mathematical analysis to assist designers in the accurate production of such a device. Worked examples are included to illustrate the procedure, and draughtsmen should find these helpful and preferable to a trial and error method of layout on the drawing board.
