Latest Patents

One of Sperber's latest patents is a tank designed for the wet processing of photographic material. This tank features a container mounted on the inside of one of its walls, which communicates with a source of processing liquid. The design includes at least one nozzle for spraying the liquid against the photographic material being conveyed through the tank. The nozzle creates a constriction in the tank, with an enlargement present below it. A movable rack equipped with several pairs of rolls advances the photographic material through the tank. Additionally, the design incorporates sheet-like guides that direct the photographic material to the nips of the rolls. The guides are pivotally mounted on the rack, allowing them to move between inoperative and operative positions, ensuring smooth operation during the processing of photographic materials.

Another significant patent involves an arrangement for introducing photosensitive strips into a developing machine. This arrangement includes an attaching compartment at the input part of the machine, which has two opposite open ends. One end communicates with the exterior, while the other connects to the machine's interior. The design features a pivoting lid that can be latched in a closed position and a separating slide that moves across the compartment. This innovative mechanism streamlines the process of introducing and transporting photosensitive strips through the developing machine.
