An apparatus for reproducing a still picture includes a flying spot scanner having its vertical deflection device for scanning a video film which has a plurality of luminance signal recorded frames and frames on which color signals are recorded together with pilot signals. Each frame is separated from another by a frame margin. A control device is provided for obtaining automatic coincidence of the position of a raster formed by the scanning with that of a frame. The control device comprises a f...

Mounted on a supporting block in spaced parallel relationship are two short shafts slotted for the reception of the rearward portions of sharp-edged resilient film squeegee blades. At least one of these shafts is pivotally mounted and its squeegee blade is urged toward the squeegee blade of the other shaft by a spring element, such as an elastic band. The liquid on the film, such as motion picture film, traveling between the two blades is removed by the sharp-edged portions thereof without damag...

A flexible and multi-directional stretchable sheet which is resistant to flame, moisture and degradation upon exposure to ultraviolet light and extreme temperature conditions, the sheet including a mixture of chlorinated polyethylene, polyvinylchloride, a heat stabilizer, a flame retardant, and a phosphate chelating agent.

A marking film including a two ply laminate layer of high density polyethylene each film of which is oriented in one direction and with the directions of orientation being offset with relationship to each other, which laminated layer is white and a backing layer on one face of the laminated layer and being of a color other than white. The laminated layer becoming substantially clear when locally deformed to reveal the backing layer color therethrough. Laminates of the invention can also provide ...

Apparatus is disclosed for enlarging and back-projecting an image on microfilm onto an essentially horizontal screen set at a fixed distance from the microfilm, the distance between reflecting surfaces and projecting lens and screen being alterable while a corresponding adjusting movement of the projecting lens, to maintain the image in focus, is effected by means of a pair of vertical camming members along which a framework supporting the reflecting surfaces moves.

Sheets such as cut X-ray films are separated from a stack by a disc positioned with its front face parallel to the top sheet of the stack and with the axis of the disc generally perpendicular to but not intersecting the top sheet. A slot extends diagonally through the edge of the disc, and an edge projects approximately the thickness of one sheet from the front face next to the slot. As the disc rotates the top sheet is picked up by the projecting edge and fed laterally through the slot to the r...

A film cassette holding a required number of monosheets may protect monosheets contained therein from impact and exposure to light, and has a built-in means for urging monosheets into a camera. Upon insertion of the cassette into a camera, the cassette is automatically opened, and monosheets are automatically loaded, in light proof conditions, from the film cassette into the camera, which is provided with a means for advancing successive monosheets to an exposure position, and the cassette is th...

A cassette for film having a forward portion formed so as to fit a foremost film sheet into a corresponding inset portion of an autoprocess camera for exposure to light directed through a camera lens, holding guide bands for retention of film-sheets, a light-proof collapsible cover to protect film-sheets from exposure to light other than that directed through the camera lens, when the cassette is mounted on a camera, and elastic elements urging film-sheets to the front portion of the cassette, w...

A film washer wherein film supporters are axially deposited in an elongated water tank, and wherein water is introduced through a bottom fill opening and deflected radially to attain a swirling washing action. An auxiliary water container is mounted alongside the water tank, and a siphon tube extends along the length of the auxiliary tank with an open end terminating near the enclosed end. A water port at the bottom communicates between the auxiliary and water tanks so that filled water creates ...

A film cartridge loaded with a roll of motion picture film having a magnetic stripe on one surface of the film is subject to shaking or impacts during handling of the cartridge which result in stepping or displacement of some convolutions of the film in a direction parallel to the axis of the film roll, especially when the film has first clocksprung in a radial direction. When stepping occurs, friction between the displaced convolution and the adjacent convolutions of the film prevents return of...
