摘要： A device is provided for use in a camera utilizing selfdeveloping film. The film in question comprises a rupturable pod of processing liquid which is sandwiched betwen a pair of photographic sheets. Attached to the exterior of one of the sheets and disposed adjacent the leading end thereof is an elongated removable feeder tab. The device is disposed within the camera and includes a pair of elongated spreader members which are biased towards one another to assume a substantially superposed relation and define an longated predetermined minimum gap through which the photographic sheets and the pod, when in a collapsed state, are caused to move. As the film moves through the gap, the pos is ruptured and the processing liquid uniformly spread between the sheets. Compression means are disposed adjacent the infeed side of the gap and provide uninterrupted pressure on the opposite marginal segments of the film sheets. Compressive pressure is continuously exerted along a wide uninterrupted band on opposite marginal segments of the film from a location substantially upstream of the spreader members into the gap between the spreader members and thereby confining the spread of the processing liquid to between the compressed wide bands formed on the marginal segments. Portions of the compression means extend into the gap and engae the film while the latter is moving therethrough. The device includes a guide means which is disposed adjacent the infeed side of the gap and directs the leading end of the film into the gap. The feeder tab carried by one of the photographic sheets is positioned over the guide member so as to circumvent the gap. The feeder tab projects outwardly from the camera housing and, as it is manually pulled therefrom, the feeder tab will cause the leading ends of the photographic sheets to pass through the gap and extend outwardly from the camera housing whereupon they may be grasped for manual pulling of the remainder of the film through the gap.

摘要： A view finder is provided for a camera wherein the latter is adapted to accommodate film cartridges or packets of two different sizes. The viewfinder is carried on the camera and is adapted to automatically vary by means of an adjustably mounted masking piece the size of the viewing area to be observed through the viewfinder so as to coordinate same with the size film being used in the camera. The adjustment of the masking piece is effected during loading of a given size film cartridge into the camera. Thus, the viewfinder facilitates proper manual aligning of the camera lens with the subject being photographed.

摘要： In the apparatus disclosed, three dichroic filters partially intercept a white light beam emerging from a light source having an elliptical reflector with a focal point at the location of the filters. The filters thus divide the beam into a white portion and an intensely colored portion. The beam enters a mixing chamber through a porthole and strikes a slanted white-opaque ceiling to form a hyperbolic section. White-opaque sidewalls coact with the ceiling to mix the white and intensely colored light. The light exists through a diffuser at the bottom of the chamber so that it can be used to illuminate a color negative in a color enlarger which focuses the light on printing paper. A cylindrical mirror at the entrance porthole reflects a part of the marginal portion of the colored part of the beam toward the white side while reflecting part of the white light into the intensely colored light. This allows the mixing chamber to blend the light and avoid a color wedging effect on the print. The diffuser at the exit of the chamber tapers from a thick center outwardly toward thinner edges. Thus, the diffuser scatters more of the light at its center and transmits more at its edges. This compensates for falloff of intensity from center to outside. The scattering of light within the diffuser causes unused light to reenter the chamber for further mixing. A matte finish on the bottom of the diffuser prevents the light which is reflected by a carrier holding the film from being rereflected onto the edges of the film.
摘要翻译：在所公开的装置中，三个二向色滤光器部分截取从具有椭圆形反射器的光源出射的白光束，其中焦点位于滤光器的位置处。因此，滤光器将光束分成白色部分和强烈着色部分。梁通过舷窗进入混合室，并撞击倾斜的白色不透明天花板，形成双曲线段。白色不透明的侧壁与天花板共同混合白色和强烈色彩的光。光通过腔室底部的扩散器存在，从而可以将色彩放大器中的彩色负片照亮，从而将光聚焦在打印纸上。入口孔口处的圆柱形镜将反射部分的白光反射到白色侧的彩色部分的边缘部分的一部分，并将其反射到强烈着色的光中。这样就可以使混合室混合光线，并避免在打印件上产生颜色楔入效果。在室的出口处的扩散器从厚的中心向外朝向较薄的边缘逐渐变细。因此，扩散器将更多的光散射在其中心并在其边缘处更多地传播。这补偿了从中心到外面的强度衰减。扩散器内的光的散射使未使用的光重新进入腔室进一步混合。在扩散器底部的无光饰面防止由保持膜的载体反射的光被再反射到膜的边缘上。

摘要： The disclosed apparatus forms part of the lamp house in a photographic enlarger. Three dichroic filters partially intercept a white light beam emerging from a light source having an elliptical reflector. The filters divide the beam into a white portion and an intensely colored portion. The beam enters a mixing chamber wherein white-opaque side walls and a ceiling coact with each other to mix the white and intensely colored light. The light exits through a diffuser at the bottom of the chamber and passes through a color slide or negative having a color image. An optical system focuses the image on printing paper. Three pivotally mounted filter holders support the filters in their respective positions. Three cams movable by manually adjustable wheels control the positions of the holders. A control arm engageable with all three of the holders simultaneously draws the filter holders out of engagement with the cams until the filters are removed from the beam. A regulating arm moves an attenuator into the path of the beam.
