Microphonograph record which is to remain stationary while information is being reproduced therefrom formed from a sheet of material and having generally V-shaped locating means formed in the sheet of material which is accessible from one side of the sheet of material. The V-shaped locating means lies in a plane generally parallel to the plane of the sheet of material. The sheet of material is provided with first and second surfaces and has information carried by the sheet of material on at least one surface thereof and arranged in a generally concentric circular pattern. The circular pattern has at its center a point which lies in close proximity to the apex of the V-shaped locating means.

Microphonograph record

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.

Film cartridge

Miniature apparatus for reproducing sound from a stationary record which comprises a base and a main shaft mounted on the base. A disc-like member is rotatably mounted on the main shaft and means is carried by the base for rotating the disc-like member. A cartridge having a stylus therein adapted to engage the record is provided. An arm assembly carries the cartridge in one end thereof and means is provided for mounting the arm assembly on the disc-like member to permit swinging motion of the arm assembly about horizontal and vertical pivot axes. The disc-like member has an arcuate slot therein through which the stylus can extend to engage the record.
