Abstract: An x-ray microfilm reader includes a microcomputer control system for controlling film loading, unloading and searching for a particular frame, as well as controlling exposure times for full-size reproductions ("blow backs") of the x-ray images. The x-ray microfilm is contained in a cartridge which is inserted into a cartridge station of the microfilm reader. When the user depresses an INDEX key, the control system automatically causes the microfilm to be withdrawn from the cartridge and wound onto a takeup reel until the first frame is aligned at a film gate. By entering a numerical value through a keyboard and then actuating a SEARCH switch, the user causes the control system to automatically drive the film until the selected frame is aligned at the film gate. The control system controls operating speeds of the drive motor as a function of the distance between the current frame and the desired frame, so that the microfilm is stopped at the proper frame without undershoot or overshoot.

Abstract: Electronic laundry machine controller apparatus for automatically synthesizing, in response to single operator program selections, complete laundry cycles or programs from laundry machine control instructions stored, independent of operator selection or control, within an electronically read memory. A read only memory is preprogrammed to store laundry machine control instructions and program synthesis instructions for compiling a large number of different laundry programs, each having laundering steps or operations preconfigured to satisfy the peculiar laundering requirements of a large number of different commercial and institutional users. Program variation select means presettable by the manufacturer or upon installation of the controller enables preselection for execution from the large number of possible laundry cycles, only those laundry machine cycles which best satisfy the user's specific laundering needs.
