Abstract: An imprinting system of the type including: a conveyer; a plurality of feeders for delivering signatures to a conveyer, the conveyer moving the signatures in a predetermined direction along a conveyer path; a printer disposed proximate to the conveyer along the path for imprinting on portions of signatures within a predetermined print field; improved in that the system further comprises: a scanner for scanning a field of view disposed along the path extending in the predetermined direction in predetermined relation to the print field and generating scanner output signals indicative of the position of the signature within the field of view; and the system for controlling the printer includes varying the position of the print field relative to the field of view in accordance with the movement of the signatures through the field of view.

Abstract: The invention provides a cutoff control system having a capture range equal to the length of the image (signature) which is highly tolerant of spurious transitions, such as lateral shifting and instantaneous interruptions of the web. A highly pipelined hardware correlation unit, cooperating with several high speed RAM devices having independent address generators, is used to cross-correlate new patterns with a reference pattern.

Abstract: A system for controlling an apparatus operating on a moving web, in accordance with a periodic characteristic of the web. Indicia of successive periods of the characteristics are generated and compared to generate control signals to the apparatus. Specifically, a cutoff control system for a web-fed printing press is disclosed wherein the effective position of the cutting apparatus along the weg path is varied in accordance with variation in the position of a maximum density change in an individual repetitive image from that of a reference image, or in accordance with a cross-correlation between the individual image and a reference image.

Abstract: Fines in the overhead vapors from an oil shale retort process in which fresh shale together with hot recycle combusted shale from a combustor are fed to a retort and at least partly fluidized by a countercurrent stripping gas stream are handled by (a) removing a portion of the fines in a vapor-solid separation (b) optionally subjecting the portion of fines to additional retorting in a fines retort (c) condensing the partially dedusted gas (d) separating the condensate into a substantially fines-free liquid oil and a wet solids and (e) recycling at least a portion of the wet solids to the retort, fines retort, and/or combustor whereby the liquid on the wet solids is recovered and/or burned and the wet solids are dried.
