Abstract
This paper is an endeavor to call attention to an engineering material which has the most favorable coefficient of friction in relation to film emulsions and bases among known commercial products. Characteristics of sapphire in fine watches, the development of industrial sapphire, and potential motion picture equipment applications are discussed briefly. The Auricon camera film gate with regard to the use of hard contact points and the mounting of sapphire contact surfaces is described and illustrated. Physical characteristics of sapphire are shown with charts and performance data. Diamond lapping compounds and the metal bonding and flame forming of sapphire are briefly mentioned.
