Abstract: TRACTION-DRIVE TRANSMISSION     ABSTRACT OF THE DISCLOSURE     The invention contemplates an improved mechanical traction drive providing a single control whereby a desired range of speed ratios between input and output shafts is selectively available, without requiring clutch connection to the power source, such as an internal-combustion engine.          The transmission involves a combination of completely mechanical friction-roller and meshing-gear planetary systems which are connected at all times, whether the single control is operated to call for a forward drive, a stop or a reverse drive of the output shaft.  For the particular disclosed form, provision is made for automatic downshifting reaction to increasing load, and major axial-reaction forces are self-contained by rotating mechanism, thus (a) avoiding substantial axial force components on main-bearings of the mechanism, and (b) reducing to very small magnitudes the requisite force for selective control actuation.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for removing redundancy of scan data of pictures by coding it to reduce the transmission time or compress the trans-mission bandwidth.  The edge states between white and black areas on the preceding line and the current line are classified into a First state in which the edge on the preceding line continues to the current line, a Second state in which the edge on the preceding line turns up on the same line, and a Third state in which the edge on the current line turns down on the same line.  In the First state, the difference in the location of the edge between adjacent lines is coded; in the Second state, coding is effected only by a state code; and in the Third state, the distance between the position of the previous state and the position of the first edge and the distance between the latter and the position of the next edge are coded.  Since the current line can be coded only processing the preceding line and the current line one-directionally and simultaneously, implementation of a coder becomes simple. Further, since correlation between adjacent scan lines is utilized, redundancy can be effectively removed regardless of whether the document is simple or complicated.
