A cassette for an x-ray film coated with a stimulable phosphor layer is formed so that a cassette memory which carries storable, recordable, readable and erasable data is rigidly attached to the cassette at the positioned spaced a predetermined distance from a given cassette corner. This position is the same for all cassettes of the same type and different formats.

An air humidifier for moisturizing air in a dry treatment device for a photographic material comprises a housing having inner walls and provided with at least one air aspiration openng and at least one air discharge opening, a moisturizable element arranged in the housing, a unit for blowing air through the moisturizable element and then through the air discharge opening to a space to be moisturized and also located in the housing, the moisturizing element being formed as a rotatable disc arranged before the air discharged opening and provided with rotary drive unit for its rotation, a light protective plate arranged between the moisturizable disc and the unit for blowing air and at least locally spaced from the inner wall of the housing so as to form throughgoing air passages, and light separating parts provided behind the throughgoing air passages and before the moisturizable disc.

An arrangement for determining two or more superimposed film sheets, particularly X-ray film sheets, in a transport after their withdrawal from the film sheet stack, has a light barrier with a light source at one side of the transport path and a photoreceiver at the other side thereof, and an evaluating circuit connected with the photoreceiver for producing a signal corresponding to the presence of two or more sheets and including a computer supplied with a value of the density of a first or test sheet introduced into the light barrier between the light source and the photoreceiver, so that the supplied value serves as a reference signal for measuring the next film sheet.

An apparatus which controls the operation of metering pumps serving to regenerate the baths in a developing machine for exposed photosensitive material issuing from a photocomposing machine has a computer whose outputs transmit appropriate signals to the metering pumps via amplifiers and whose inputs respectively receive signals from a scanner serving to ascertain the width of photosensitive material in the photocomposing machine and the composition of the emulsion, from a forward-reverse counter which ascertains the total length of photosensitive material admitted into the developing machine per unit of time, and from an integrating circuit which receives signals denoting the amounts of radiation issuing from a cathode ray tube or a laser recorder and impinging upon the photosensitive material. This renders it unnecessary to monitor the condition of the baths and/or the photosensitive material in the developing machine.
