title: [Manufacture of control knobs for medical devices and apparatus].
abstract: Control knobs having rigid projections in the setting port which incise into the shaft of the control element possess operating advantages over the knobs of other constructions. But they are unprofitable in production because of the mechanical treatment method. Considerably technical and economical higher profit can be attained by casting the knobs according to melted models.
