Abstract: In processing a video signal, vertical correlation is utilized between video signals of successive line intervals. Video signals from the two line intervals are examined, their existences, polarities and magnitudes between them. If both signals exist with the same polarity, a smaller signal in magnitude is derived at a system output and otherwise no signal appears at the output. This system can be applied to a color television camera circuit.

Abstract: A plurality of strands of magnetic recording tape are withdrawn in parallel feed paths from tape supply reels and are fed by a tape feed assembly at a controlled, high speed rate to a takeup assembly and wound thereat on a corresponding plurality of tape cartridge spools, of the endless tape type, that are rotated by a takeup shaft. The takeup shaft is driven at a spooling rate that is faster than the feed rate and each of the spools are drive coupled to the takeup shaft by individual, adjustable slip-clutch hub assemblies which cause the tape strands to be wound at individually adjustable spooling tensions which must be carefully regulated to insure proper operation of the spooled tapes when assembled in the endless tape cartridge. Each of the supply reels holds sufficient tape for filling numerous individual spools and as each set of spools on the takeup shaft becomes full, the strands of tape are cut and the full spools are withdrawn and replaced with empty spools.

Abstract: A method and means for adjusting a log into a position in front of a saw necessary to obtain a maximum yield. The log is turned in such a manner that any curvature is positioned in a plane parallel to the plane of the saw members and is then is displaced sidewardly in such a manner that a plane containing the log end centers becomes properly positioned in relation to the plane of the saw members. The positioning of the log into the desired rotational position is carried out at a point to the side of the saw line with a simultaneous scanning of the log dimensions electronically and storing of such information in a computer. The log, having been turned into the desired rotational position, is then held in that position and is fed laterally generally into the saw line where the log is side-adjusted into a proper orientation longitudinally in relation to the saw members.
