发明名称 VORRICHTUNG ZUM HALTEN VON BLATTFOERMIGEN FILMEN
摘要 <p>A container for X-ray films is of the type wherein at least one side of the film is contacted by a stratum of fluorescent material. The fluorescent material is biased against the respective side or sides of the film by two layers which consist of ferromagnetic and/or magnetic material, flank the film and attract each other. Such layers can be applied to the inner or outer sides of sheet-like carriers consisting of synthetic plastic material. The aforedescribed film, stratum or strata, layers and carriers may but need not be inserted into the space between the rigid or flexible walls of an envelope. The envelope can be dispensed with if the carriers consist of opaque material. Since each of the two carriers can support the respective layer and the respective stratum of fluorescent material, the thickness of the entire package is minimal and the film can be placed into close proximity of one or more objects to be imaged so as to obtain sharp images of such object or objects. The distance between the film and the object or objects is reduced still further if the layers of ferromagnetic and/or magnetic material are applied to the inner sides of the respective carriers because the distance between the layers is then small and the thickness of such layers can be held to a minimum. The thinnest packages are obtained by mixing the ingredients of the layers with the ingredients of the fluorescent strata and applying to each carrier a single coat of the resulting suspension so that the coat is disposed between the respective carrier and the corresponding side of the film.</p>
