摘要： An apparatus for cataloguing and storing photographic prints and negatives in the same aesthetically designed case. In one embodiment, a negative album is placed in one compartment of the case, and a second compartment of the case retains a plurality of separately bound and identifiable photograph albums. The negative albums holds a plurality of conventional paper negative/print wallets, labelled to correspond to respective photograph albums stored in the apparatus. Each individual photograph album is designed for facile addition, removal, substitution and viewing of individual photographs; and is attached to a hand-grippable hanger element to permit both removal of albums from the case as well as their return to the case. The apparatus performs the same function whether vertically or horizontally disposed.

摘要： An improved transparency holder is provided for use in supporting and positioning a transparency in a light and image projection apparatus, such as a photographic enlarger. It includes a pair of opposed carrier plates having an aperture for coaxial alignment with a light beam. Disposed therein are mask means, which are another pair of opposing apertured plates for releasably holding the transparency therebetween in coaxial alignment with the light beam. The mask means are positioned by registry pin and hole means, and releasably retained thereat by magnetic means. A cassette means also defines an aperture for coaxial alignment with the light beam and is adapted to removably receive the carrier means. Moveable wedge means are externally accessible from the cassette and cooperate with the mask means for selectively releasing the transparency for movement. Bias means within the cassette compresses the mask means to hold the transparency in clamped engagement when the carrier is in the cassette.

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. The filters divide the beam into a white portion and an intensely colored portion. A mixing chamber receives the beam to mix the white and intensely colored light which is used to illuminate a color slide or negative having a color image. Suitable controls coupled to the filters move the filters into and out of the beam along a continuous path between predetermined limits that define the maximum and minimum color densities of the light emerging from the chamber. A number of readouts coupled to the controls display the extent to which the filters have been moved between the limits and represent the colored density of the position of the filters. The readouts exhibit a given reading for a predetermined color and density. When the character of the beam is changed by changing the source, it is necessary for the controls to readjust the filters to different positions in order to obtain the predetermined color and density. A coupler decouples the readouts from the controls so that the readouts can be set to the same readings for the predetermined color and density when the controls cause the filters to produce the predetermined color and density. The controls and readouts are then recoupled.
摘要翻译：所公开的装置在照相放大器中形成灯室的一部分。三个二向色滤光器部分截取从光源出射的白光束。滤光器将光束分成白色部分和强烈着色部分。混合室接收光束以混合用于照亮彩色幻灯片或具有彩色图像的负片的白色和强烈着色的光。耦合到滤波器的合适的控制器沿着限定从腔室出射的光的最大和最小颜色密度的预定限度之间的连续路径将滤光器移入和移出光束。耦合到控件的多个读数显示滤光器在极限之间移动的程度，并表示滤光器位置的着色浓度。读数对于预定的颜色和密度呈现给定的读数。当通过改变源来改变光束的字符时，控制器需要将滤光片重新调整到不同的位置以获得预定的颜色和浓度。耦合器将读出与控制器分离，使得当控件使滤波器产生预定的颜色和密度时，读出可以被设置为相同的读数，用于预定的颜色和密度。然后重新配置控制和读数。

摘要： Circuits for controlling the amount of light received from a subject being photographed and terminating the operation of a flash lamp are disclosed. The circuits include a photosensitive element producing a signal related to the light received from the subject and a signal generator producing a signal having a predetermined function of time. The two signals are combined and when they achieve a predetermined relationship, the operation of the flash lamp is terminated.

摘要： A slide projector for holding a rotary tray in a vertical condition in a troughway is also adapted to hold rectangular trays in the same troughway. The advancing mechanism is adapted to sequentially move either type tray while providing for the ready removal of the vertical or rectangular tray from the troughway. The rotary tray is provided with extending hub portions sized to seat in open top cup supports provided in the projector housing. These cup supports act as both vertical and horizontal retaining means for the rotary tray.
