Abstract: Apparatus for transporting photographic sheet material from one unit to another, such as from an X-ray film cassette unloading unit to a processing unit, comprising a housing located between and locked to said units in a novel manner, the housing containing a film transfer device attachable to a wall of the housing adjacent the unloading unit to receive film through an entry opening, and readily positionable to transfer film to either of two exit openings in an opposing wall of the housing to accommodate processing units of different types having entry openings located at different elevations, the locking device also cooperating in the positioning of the transfer device.

Abstract: Apparatus for removing a sheet from a container such as a sheet film from a cassette, by a suction device mounted for movement rectilinearly at an angle to the plane of the sheet.

Abstract: Method and apparatus for use in X-ray cassette unloading and loading apparatus, including novel detection of presence or absence of film in the cassette and the position thereof in the upper or lower cassette part, utilizing radiation, such as infra-red, to which the film is not sensitive. Radiation is directed into each cassette part after opening and the radiation reflected from the respective parts is compared. The radiation means, as well as means for holding the cassette parts in open position and air jet means for releasing film from the upper cassette portion, are all mounted on parallelly moving guide members which engage the lateral edges of the cassette to position it.

Abstract: Apparatus for loading and unloading x-ray film cassettes of various sizes, using an air jet to release a sheet of film from a pivotally open upper cassette part, the air jet nozzle being carried by a lever arrangement such that the nozzle is moved upwardly with the upper cassette part as the latter moves to its open position.

Abstract: Cassette centering device for an X-ray cassette loading and unloading device using two parallelly movable guides engageable with the side edges of the cassette, the guides being movable by a lever arrangement driven by a motor, the lever arrangement including a link having two telescoping parts and biasing means constituting force absorbing means for cushioning the engagement of the guides with the cassette and compensating for motor overdrive.

Abstract: Container for a stack of sheets such as photographic film or paper, which is readily adaptable to a wide variety of formats by inserting plug-in elements into recesses in the bottom alone or in both the bottom and the cover of the container.

Abstract: In a device for holding down the lower cassette portion (19a) of an X-ray film cassette which is located in a cassette unloading and reloading apparatus, a hold-down lever (20, 21) is mounted to each of two parallely guided bars (10, 12) movable towards and away from each other respectively, said hold-down lever being pivotable into, and out of the transport path of the X-ray film cassette to accurately position said cassette. Each hold-down lever (20, 21) comprises a control arm (20a, 21a) resting against each of the two side walls (19d, 19e) of the upper cassette portion (19c). Since the control arms (20a, 21a) are upwardly inclined such that they form control surfaces facing the side walls (19d, 19e) of the upper cassette portion (19c), the hold-down levers (20, 21) are held in engagement with the lower cassette portion (19a) when the upper cassette portion (19c) is in its open position and are disengaged from the lower cassette portion (19a) when the upper cassette portion (19c) is in its closed position.
