Abstract: ABSTRACT OF THE DISCLOSURE         Film cartridge for use in viewing motion picture film having means forming a framework with an index plate with an aperture therein.  A continuous length of film having perforations along one edge thereof is carried by the framework.  Guide means is provided on the framework for guiding the film over the index plate and past the aperture.  Means is provided for advancing the film frame by frame past the aperture.  A spool is rotatably mounted on the framework.  The spool has a central hub and a film supporting surface extending radially from the hub so that the hub extends away from the surface in a direction generally perpendicular to the surface.  The spool has an annular rim spaced from the hub and extending away from the surface and in the same direction as the hub.  A portion of the length of film is formed as a roll and is disposed in the spool with the hub in the center of the roll and with the rim on the outside of the roll so that the film can be payed out continuously either from the inside of the roll or the outside of the roll during movement past the aperture.

Abstract: ABSTRACT A fluid expandable drum for building portions of tires in a tire building machine includes an annular supporting drum (12) and an expandable annular tube element (10) having an inner peripheral surface supported on the annular drum. The tube element includes an outer peripheral surface upon which support means (40) is secured for movement therewith. A plurality of shoe members (36) are connected (52, 42) to the support means for movement therewith with the shoe members defining an annular building surface (38) thereon which is movable in a radial direction toward and away from the annular support drum upon contraction and expansion, respectively, of the tube element. The tube element is expanded to expand the diameter of the building surface to enable a tire portion to be built thereon and retracted to decrease the diameter of the building surface to enable a build tire portion to be removed therefrom.

Abstract: ABSTRACT  "Indirect metal extrusion and tube press and    a sealing plate and a pressure plate therefor"      In order to prevent heat loss by conduction from the billet and billet container in an indirect extrusion press, the sealing plate, which closes off one end of the billet container bore, is made in two parts which are spaced apart when an extrusion stroke is not taking place so that an air gap appears between the two parts to interrupt the path of heat conduction through the sealing plate to the rest of the extrusion press.  The air gap may be produced in the pressure plate, between the sealing plate and the moving cross-head, instead of or in addition to the gap in the sealing plate.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement to allow easier detaching of a disk memory module from its magnetic attachment to the spindle of a front loading disk drive. In one such type of drive, manually pulling a door open actuates a track-mounted carrier which lifts the disk module from the spindle, breaking the magnetic attraction between them, and transporting the module to the open door for manual removal.  To reduce the force necessary to break the magnetic attraction, this invention employs an actuator fixed to the carrier which engages a crank mechanism when the carrier is being pulled to the opening. The crank mechanism pushes against the underside of the module and assists its breaking loose from the spindle.  A spring holds the crank assembly in position to re-engage the actuator when the carrier is in the module-detached position.
