Abstract: A motion picture film shipping and handling case unit is adapted to be used in conjunction with a motion picture film that is supported on a flange, [such as a flange and hub unit as defined in U.S. patent applications Ser. Nos. 07/715,684, 07/641,298 and 07/584,793,] or which is supported only on a hub, including a hub unit such as disclosed in these three patent applications. The case unit includes a film packing elements and hub engaging elements as well as releasable fastener that engage the hub and releasably attach the hub to the case. The case includes a lap joint and special film supporting straps can be used to attach the film to the case unit if no flange is used.

Abstract: A motion picture film shipping and handling case unit is adapted to be used in conjunction with a motion picture film that is supported on a flange, or which is supported only on a hub, including a hub unit such as disclosed in these two patent applications. The case unit includes a strap surrounding the outer perimeter of the unit, a plurality of straps connected to a handle and locks. The locks include a lap joint on the case unit and a special case lock attached to the case unit.

Abstract: A motion picture film shipping and handling system is adaptable for use on either a platter-type movie projector system or on a reel-type movie projector system. The system includes two film supporting flanges with a collapsible hub located therebetween. A central supporting hub is releasably connected to the collapsible hub, and fasteners releasably attach the elements together. A shipping case contains the flanges and the film in a manner which dissipates impact forces to protect the film and the flanges.

Abstract: A motion picture film shipping and handling unit is adaptable for use on either a platter-type movie projector system or on a reel-type movie projector system. The unit includes two film supporting flanges with a hub located therebetween. A central supporting hub is releasably connected to the hub, and fasteners releasably attach the elements together. A locking ring connects the flanges together and a flexible film winding ring surrounds the locking ring. A packing ring formed of one or more separate annular sections is located between the locking ring and the film winding ring. A handling assembly assists in moving a shipping and handling unit into position adjacent to a platter of a platter-type motion picture projector. Another form of the handling assembly includes a platter system that has the platters thereof mounted on pivots and telescoping arms to move into position to accept film from a vertically oriented film shipping and handling unit. Ramps elevate the shipping and handling unit as necessary.

Abstract: A film holding reel includes a deformable hub on one portion thereof, and a compound lever hub deforming mechanism is used to deform that hub from a film supporting size and configuration to a film releasing size and configuration. The lever mechanism is adapted to move easily from a position in which the hub is undeformed, to an intermediate position, and then to require further manual actuation to move to a position in which the hub is in the film releasing size and configuration. A selected film portion can be changed using the film holding reel.

Abstract: This invention relates to a film winding and rewinding machine characterized by a single unidirectional motor being used in cooperation with a pair of electrically-actuated clutch/brake units and a suitable power train to actuate the take-up reel in either direction. It also encompasses an automatic mechanism responsive to the tail end of the film leaving the hub of the supply reel to shut off power to the motor and stop the take-up reel in both the FORWARD and REVERSE modes. It further envisions using the drag of the friction brake in whichever of the clutch/brake units is actuated into its clutch mode to apply a variable tension to the film coming off of the reel functioning in the capacity of the supply reel.

Abstract: This invention relates to an improvement upon the film winding and rewinding apparatus forming the subject matter of my copending application Ser. No. 666,187 filed Oct. 29, 1984, by a replacement of its former manually-shifted electrochemical reversing system for changing from a so-called "A-wind" to a "B-wind" with an electromagnetic one employing a pair of electromagnetic clutches on parallel counterrotating output shafts operatively linked together with a belt and pulley power transfer mechanism which cooperates with the clutches to impose a drag upon the supply reel regardless of which direction it is being turned by the power supplied to the take-up reel. The invention also encompasses an electromechanical circuit in which an idler spool responsive to the tension in the film passing between the supply and take-up reels actuates a potentiometer which, in turn, lessens the drag on the supply reel as the tension increases.
