Abstract: A transport mechanism has two driven gears driven by a driving gear therebetween and having pivotally attached cranks at pivot points maintained at the same elevation as the driven gears rotate. The upper end of the cranks are attached to a horizontal moving guide bar. The moving mechanism is supported beside a fixed guide plate formed with a loading slot at the input end, a sloping edge at the output end and a number of equally spaced vertical slots therebetween. A film carrier has end rods which may rest on the moving guide bars and be lowered in the slots. Film chips in the film carrier advance from the loading slot into a developing tank. The mechanism then lifts the carrier with the film chips above the carrier tank and into a wash tank, then from the wash tank into a fixing tank, then from the fixing tank into a wash tank, then into a drying chamber and then upon an output ramp.

Abstract: A copy camera has a lens board positioned by a lens lead screw and a copyboard positioned by a copyboard lead screw. A ratio-selecting knob rotates the shaft of a lens counter that is connected by a flexible coupling to spur gears that rotate the lens feed screw so that the count in the lens counter corresponds to the ratio of image size to object size. Spur gears intercouple the lens counter shaft to the tape advance drum that carries a tape with numbers denoting a copyboard counter setting for establishing an object distance between copyboard and lens for maintaining an object at that distance in sharp focus for attaining the ratio indicated in the lens counter. A copyboard setting knob rotates the copyboard counter shaft that is connected by a flexible coupling to the copyboard lead screw to enable an operator to set the copyboard counter to the value displayed on the tape drum.

Abstract: Three or more tanks holding photographic processing solutions are arranged in series in a processing machine that transports photographic material sequentially in and out of each tank by turn-around assemblies inside each tank and by crossover assemblies between adjacent tanks. Each assembly includes a driven roller and an endless belt which holds the processed material against the periphery of the driven roller. Similar assemblies feed the first tank at the input end of the machine and deliver the material from the last tank at the exit end of the machine.

Abstract: A film holder receives film chips for developing and enters through an input opening where a transport mechanism carries it into a developer tray having a thermistor for providing a signal representative of the developer temperature. This signal is used to control the development time to be inversely proportional to temperature. At the end of the development cycle the transport mechanism lifts the film holder from the developer tank, carries it to the fixing tank and deposits it in the fixing tank. At the end of the next development cycle, the transport mechanism lifts the film holder from the fixing tank, transports it to the wash tank and deposits it in the wash tank. At the end of the next development cycle, the transport mechanism lifts the film holder from the wash tank and deposits it in the drying chamber where forced hot air dries the developed fixed washed film chips. They may be removed through an exit door.
