Abstract: An automatic film processor for processing roll, sheet or disk film houses the film to be developed, which is disposed in a light tight housing, preheats the chemical solutions to the proper temperature and pumps them, in turn, into the reservoir formed by the base of the removable film drum in which the film is positioned and provides rotary and linear agitation for the film. The machine includes a linear selective valve capable of selecting any one of a plurality of chemical solutions for use in developing of the film and carefully purges the system prior to preheating and supplying the next chemical for use in the developing process.

Abstract: A channel interface multiple virtual control unit controls a plurality of classes of terminal sessions on a graphics system workstation, the multiple virtual control unit includes lookup tables having indicia related to a class of display session to be enabled for controlling a workstation in either a alpha-numeric display mode or a graphics display mode.
