Definitions

• the ⁇ innovatioh relates to a device for. mp ⁇ ov * g the air, in " particular for raising the level, of humidity inside apparatus, in.-particular, apparatus for unloading and loading X-ray film cassettesV -
• sparks may " develop which lead to the film being "exposed", thus causing undesired fogging. More ⁇ over because of the air being so dry, flatness of the X-ray film sheet ' s in the X-ray film cassette cannot be ensured.
• the device comprises a container with an amount of water which can be metered, a liquid-absorbing, air-permeable filter and a ven ⁇ tilator associated with said water container.
• Fig. 1 is a longitudinal sectional view of the subject matter of the innovation
• Fig. 2 is a sectional view of the subject matter of the innovation along line I-I according to Fig. 1, and
• Fig. 3 is a partially sectional view of the subject matter of the innovation along line II-II according to Fig. 2.
• the device comprises a water container 3 covered by a lid 7.
• Said container can be filled with water up to one quarter of its height, using a metering element described in detail further below.
• the water container 3 is arranged at a suitable place on a wall 1 of an apparatus for unloading and loading X-ray film cassettes, said wall having a rectangular opening la.
• the container In its rear wall 4, the container has a first rectangular opening 4a which is substantially flush with the wall opening la in the apparatus, and in its front wall 5, it has a second circular opening 5a. Both openings 4a and 5a are located above the water level 17a.
• a liquid- absorbing and air-permeable filter pack 10 is positioned such that it covers opening 4a, extends beyond the lower edge of said opening 4a and is immersed into water 17.
• the filter pack 10 When the lid 7 is open, the filter pack 10 can be moved into position by means of a hahdle bar 10a arranged at its end face, and slid downwardly from above between two vertical guide rails 8 which extend on either side of opening 4a.
• a flexible light- shielding element 2 is provided between the wall 1 of the apparatus and the rear wall 4 of the container, said light- shielding element surrounding the wall opening la in the apparatus and the opening 4a in the rear wall 4 of the con ⁇ tainer.
• a ventilator housing 12 screwed to the " front wall 5 of water container 3 also comprises a circular opening, 12a which is flush with the circular opening " 5a in the front wall 5 of the container.
• a radial ventilator 14 is provided at a small distance from openings 12a and 5a, said ventilator being driven by a motor 13 attached to the housing 12.
• the radial ventilator 14 sucks in the air through an air entrance opening 12b in the upper side of the ventilator housing 12, said opening being covered by an exchangeable air filter ! 15, and blow the air into the cassette loading and unloading apparatus throug the openings 12a and 5a and via the filter pack 10 fully soaked with water.
• the speed of the radial ventilator 14 can be varied such that-air with a higher or lower degree of humidity is blown into the apparatus, if necessary.
• Reference numeral 20 relates to an inlet connection inserted into a side wall 6 of water container 3. Said inlet connection is associated with a float switch 21 and 22.
• a water supply can 24 is arranged directly at the wall 1 of the apparatus and is connected with the inlet connection 20 via a water feeding hose 23.
• the float switch 21 and 22 provides for the water level to always have a constant height.
• the container can also be connected to the water mains via a suitable plumbing connection.
