摘要： A suction device is movable between a receiving position in which it removes a sheet of film from a magazine and a delivery position in which it transfers the sheet to a conveyor. The effective width of the suction device approximates or equals the width of the smallest sheet of film to be transferred. Sheets having a width greater than the smallest width are gripped in the region of one end thereof leaving the remainder of such a sheet free to deflect. In order to permit proper transfer of all sheets into the conveyor, the latter is provided with grooved rollers which lift the deflected portions of larger sheets into the conveyor. In the delivery position, the suction device is located opposite one portion of the conveyor. The conveying force exerted by this portion of the conveyor is smaller than the gripping force which the suction device exerts on a sheet but larger than the conveying force exerted by a laterally adjacent portion of the conveyor. The portion of a sheet in the latter part of the conveyor constitutes a moment arm when the sheet enters the conveyor and the vacuum in the suction device fails to shut off. The tendency is for the sheet to rotate about an axis which is located in the vicinity of the suction device and is normal to the sheet. This tendency is reduced by maintaining a relatively low conveying force in the portion of the conveyor remote from the suction device and maintaining a relatively high gripping force for the suction device.

摘要翻译： 抽吸装置可以在接收位置之间移动，在该接收位置，其从盒中取出一片薄膜，以及将片材传送到传送带的传送位置。 抽吸装置的有效宽度近似于或等于要转移的最小薄膜片的宽度。 具有大于最小宽度的宽度的片材被夹持在其一端的区域中，留下这样的片材的其余部分自由偏转。 为了允许将所有片材适当地转移到输送机中，后者设置有槽辊，其将较大片材的偏转部分提升到输送机中。 在输送位置，抽吸装置与输送机的一部分相对。 由输送机的该部分施加的输送力小于抽吸装置施加在片材上但是大于由输送机的横向相邻部分施加的输送力的夹紧力。 当纸张进入输送机并且抽吸装置中的真空不能关闭时，输送机后部的片材部分构成力矩臂。 倾向于片材围绕位于抽吸装置附近的轴线旋转并且与片材垂直。 通过在输送机的远离抽吸装置的部分保持相对低的输送力并且为抽吸装置保持相对较高的夹持力来减少这种趋势。

摘要： An arrangement for introduction of a film magazine into a film-processing device has a housing which defines an inlet slot through which the film magazine is inserted. The film magazine has a film stack carrier provided with at least one opening for removal of the film and a casing member which is movable with respect to the film stack carrier. In order to guarantee the light-tight shielding during the introduction of the film magazine, a shutter is provided along the inlet slot which is parallel movable within the interior of the housing and serves as support for the film stack carrier. The shutter has a circumferential edge which cooperates with a respective circumferential edge of the housing for providing a first light-tight shielding and a second light-tight shielding is provided through cooperation of the circumferential edge with a respective groove provided in the casing member.

摘要翻译： 用于将胶片盒引入胶片处理装置的装置具有外壳，该外壳限定了胶片盒被插入的入口槽。 胶片盒具有胶片堆叠载体，其设置有至少一个用于移除胶片的开口和可相对于胶片堆叠载体移动的壳体部件。 为了保证在胶片盒的引入过程中的不透光屏蔽，沿着入口狭槽设置一个挡板，该挡板可在壳体内部平行移动并用作胶片堆叠载体的支撑。 闸门具有与壳体的相应圆周边缘配合的周缘，用于提供第一不透光屏蔽，并且通过圆周边缘与设置在壳体构件中的相应凹槽配合提供第二不透光屏蔽。

摘要： A cassette for sheet film has a cover and a bottom which are hinged to one another along a longitudinal edge of the cassette. Locking elements for locking the cover and bottom when the cassette is closed are arranged at the opposite longitudinal edge of the cassette. The cover and bottom cooperate to define a film compartment and the bottom has a rigid, flat wall for supporting a sheet of film. The cover has a window for exposing the film in the compartment and is further provided with a slot which slidably receives a shield for protecting the film against light until such time as the film is to be exposed. A resilient rim is mounted on the cover and extends around the window. The rim is arranged to press the margins of the film against the rigid wall of the bottom when the cassette is closed. The hinged connection of the cover and the bottom causes the rim to contact the film progressively as the cassette is closed so that the rim stretches the film flat over the rigid wall of the bottom. The pressure of the rim on the margins of the film after the cassette has been closed insures that the film remains flat regardless of the orientation of the cassette.

摘要翻译： 用于片状薄膜的盒具有盖和底部，其沿着盒的纵向边缘彼此铰接。 当盒子关闭时锁定盖子和底部的锁定元件布置在盒子的相对的纵向边缘处。 盖和底部配合以限定胶片隔室，底部具有用于支撑薄膜的刚性平坦壁。 盖具有用于将胶片暴露在隔室中的窗口，并且还设置有槽，其可滑动地容纳用于保护膜的屏蔽件，直到膜暴露的时间为止。 弹性边缘安装在盖上并围绕窗户延伸。 轮辋设置成当盒子关闭时将胶片的边缘压在底部的刚性壁上。 盖子和底部的铰接连接使得边缘随着盒子的关闭而逐渐接触薄膜，使得边缘将薄膜平坦地延伸到底部的刚性壁上。 在盒子已经关闭之后，胶片边缘上的边缘的压力确保膜片保持平坦，而与盒的取向无关。

摘要： An arrangement for closing and opening a film sheet cassette, particularly an X-ray film cassette, has a bottom element, and a top element provided with a projection and movable relative to the bottom element between closed and open positions. A sliding element is provided having a projection engageable with the projection of the top element in the closed position, and disengageable from the same in the open position. A spring member urges the sliding element into and retains the same in engagement with the projection of the top element in the closed position. An elastic detent element retains the sliding element when the latter is disengaged from the projection of the top element in the open position. The elastic detent element is actuated by the top element when the latter moves from the open position into the closed position, so that the sliding element ceases to be retained by the elastic detent element and is urged by the spring into the engagement of the projection of the top element.

摘要： X-ray film in a cassette or camera is magnetically gripped by a pair of magnetic units which engage opposite sides of the film. Each of the units includes a sheet of magnetic material and an intensifying screen located on that side of the associated magnetic sheet which faces the other unit. The units have cooperating first portions which engage a first region of the film and cooperating second portions which engage a second region of the film. The units are designed in such a manner that the magnetic force of the second portions exceeds that of the first portions so that the second region of the film is gripped more strongly than its first region. Furthermore, the units are arranged such that the second portions thereof engage the film no later than the first portions thereof. In this manner, entrapment of air bubbles on the surface of the film is prevented and image quality is improved.

摘要： A film cassette, particularly an X-ray film cassette, includes a housing which bounds a compartment for accommodating a film and having an opening for exposing an image on a predetermined portion of the film in the compartment. The opening is light-tightly closed by a closure which is displaceable between its closed and open positions and which is latched in its closed position by a latching member which is pivotally mounted on the closure and engages the housing at one of its ends. The other end of the rocker is accessible to an actuating pin of an exposing device through an access opening in the closure, so that the actuating pin can pivot the rocker into its releasing position in which the closure is free to move towards its open position, and displace the closure between its closed an open positions. When the closure is open, the exposing device exposes data onto a portion of the film in the cassette which is aligned with the opening.

摘要： A cassette with two chambers for discrete cut films has a centrally disposed plate-like partition with two identical sides, and a pair of identical covers each of which is adjacent to a different side of the partition and is pivotably attached to the partition by a hinge for movement between an open and a closed position. The covers have exposure apertures and carry slidable plate-like shutters which can slide in slots of the respective covers to permit or prevent entry of light by way of the respective apertures. The film chambers are separated from each other by the central portion of the partition, and the latter further carries locks for releasably holding the covers in their closed positions. The lock for one of the covers is provided at that side of the partition which is adjacent to the other cover, and vice versa. The hinge or hinges for one of the covers are provided on a first marginal portion of the substantially rectangular partition, and the lock for such one cover is provided on a second marginal portion which is parallel to the first marginal portion. The hinge or hinges and the lock for the other cover are respectively provided on the second and first marginal portions of the partition.
