A disposable package for cut photographic film and a holder adopted for use therewith. The film package provides a light excluding envelope into which is inserted a planar carrier bearing a sheet of photographic film affixed thereto by an adhesive backed opaque mask element. One end of the carrier has an elongated tab which, together with the end of the envelope, extends substantially outside the holder when the film package is fully inserted therein, and which may be grasped along with the envelope to facilitate withdrawal of the package from the holder. The open end of the envelope is rendered light tight when the carrier is fully inserted therein by the engagement of the edges of the open end with recesses in an elongated transverse clip attached to the carrier at the end opposite the tab. The holder comprises a top portion having a light transmitting window therethrough and a bottom portion, the top and bottom portions being positioned in parallel spaced relationship to each other so as to define a path for the insertion and withdrawal of the film package therebetween. The top portion is moveable relative to the bottom portion between a first relatively more distant position and a second relatively closer position and is biased in the first position by a pair of wave springs, which also serve to hold the film in the plane of focus.

A real time weather information access and distribution system having a central switching and interface unit accessed at least in part via a commercial telephone network. A remote weather station is selected by the incoming caller by means of a "decision tree" process using a touch tone phone, and the central switching and interface unit makes contact with a local interface unit at the selected geographically remote weather reporting station. Weather information being produced and broadcast locally by the weather reporting station is then provided to the geographically remote incoming caller on a real-time basis via the local interface unit, being in communication with said central switching and interface unit, and thence to individual callers desiring said real time weather information. The central interface unit includes means for allowing a plurality of incoming callers to be simultaneously provided with the same local weather information from the same desired locality, without said incoming callers being able to interact with other callers or affect operation of said central interface unit. At least one of the local interface units includes a bridge tap coupled to the NOAA weather radio console.
