Abstract: The present invention relates to a patch which is easily applied to motion picture film, a jig and a method for using the same. The patch may act as a splice to connect two lengths of film which require repair or which must be joined together to produce a complete presentation. The patch may also be applied along a predetermined position of the film to carry control information which may be used to control the sequence of events in a movie theater. In some applications, the patch may serve both a splicing as well as an information-carrying function. The patch can be rapidly and accurately positioned and attached to the film by use of a novel splicing jig and results in a splice which does not leave any adhesive residue about the film sprocket holes or on the jig.

Abstract: A positive lubrication delivery system for lubricating a rotatable gear comprises a stationary shroud configured and dimensioned to encompass a segment of the gear to be lubricated. The shroud defines with the gear segment, intermediate the circumferential outer surface of the gear segment and the adjacent surface of the shroud, a channel of diminishing clearance in the direction of gear rotation. Lubricant introduced into the channel is confined and subsequently caused to be spread over the circumferential outer surface of the gear in response to its rotation.
