Abstract: An X-ray film cassette has body and cover parts movable relative to one another between open and closed positions and provided with locking elements, magnetic and counter plates associated with these parts and attractable to one another, at least one reinforcing foil arranged to be brought together with a film between the magnetic and counter plates, wherein the reinforcing foil has a surface arranged to face toward the film and being rough with a roughness of between 10 and 60 microns.

Abstract: An x-ray cassette of the type having a film buckler member is characterized in that the film engaging edge of the buckler member extends substantially perpendicular to the plane of the film. The film engaging surface of the buckler is further provided with upper and lower film catches and a biasing member to retract the buckler member away from the path of the film.

Abstract: In an X-ray film cassette, a front cover and a bottom cover are severally formed of carbon fiber reinforced plastics. A grid member for the removal of scattered X-rays is bonded to the inside of a panel of the front cover, and a coating layer for protection is provided to cover the whole surface of the grid member on the exposed side thereof. The coating layer is also formed of carbon fiber reinforced plastics.

Abstract: An X-ray photography cassette incorporating an automatic peeler for removing the film from the cassette. The cassette includes a frame and a front plate mounted on the frame and with a rear cover coupled to the frame through hinges. Intensifying screens are positioned adjacent the front and rear cover. A peeling member is elastically coupled to one of the frame or rear cover and extending into a recess or cut-out portion formed in the intensifying screen. A space is provided between the peeling member and the other intensifying screen for receiving the film.

Abstract: An x-ray film cassette includes two cassette parts which are connected at one side by a hinge and which are cylindrically curved as considered in a plane normal to the hinge. The cassette part which constitutes the bottom carries a foil of ferromagnetic material floatingly supported on an elastic strip-sloped peripheral frame, and an intensifying shield supported on this foil, while the other cassette part which constitutes the top carries a magnetic plate supported on elongated projections of the cassette wall and supporting another intensifying shield. In the closed position of the cassette, the magnetic plate attracts the ferromagnetic foil to thereby eliminate air inclusions between the intensifying shields and the x-ray film interposed therebetween.
