Abstract: A pollution control apparatus (10) for controlling water-based liquid waste includes a vacuum distillation vessel (14) for separating water-based liquid waste into a distilled water component and a pumpable sludge component. A pH control system (12) allows the vacuum distillation vessel (14) to operate at maximum efficiency, and a purification system (22) allows the distilled water component to be purified to a level capable for reuse in chemistry, or else suitable for direct discharge into a municipal sewer. A microprocessor allows the apparatus (10) to operate automatically.

Abstract: A roll film processor for developing film wound into a roll. The processor has a plurality of substantially aligned tanks containing processing liquids. A removable film drive module having a "U" shaped section for each tank carries the film along a serpentine path through the tanks. Each "U" shaped section has down path leg for carrying the film into the liquid and an up path leg for carrying the film out of the liquid. The rollers for moving the film are positioned outside the liquid. Opposed "V" shaped grooves guide the edges of the film in the liquid. One of the grooves is on a front portion of the drive module and the other is on a rear portion. If a jam occurs, the film drive module is removed from the processor and opened by removing retainer clips by hand from retainer pins. The grooves are thereby separated allowing removal of the jammed film. Reassembly of the film drive module on the processor is facilitated by latitudinally flexible couplers for the module drive shafts.

Abstract: An apparatus for automatically processing film discs including a transport system for moving the discs through successive processing stations and a friction drive system for spinning the discs at each station for agitation and/or drying. The transport system utilizes a unique carrier spindle having a nipple on one end thereof upon which a group of film discs is removably mounted. The transport system successively transports a loaded carrier spindle from one processing station to the next. At some stations the carrier spindle is positioned so that the film discs carried thereby enter a liquid tank thereat and at other stations the spindle is positioned to facilitate disc drying. The friction drive system includes a drive belt which frictionally contacts the carrier spindle at each station for spin agitation and/or drying.
