Abstract: A video encoder generates a syntax element that indicates whether a video unit of a current picture is predicted from an external picture. The external picture is in a different layer than the current picture. Furthermore, the video encoder outputs a video data bitstream that includes a representation of the syntax element. The video data bitstream may or may not include a coded representation of the external picture. A video decoder obtains the syntax element from the video data bitstream. The video decoder uses the syntax element in a process to reconstruct video data of a portion of the video unit.

Abstract: An FCC apparatus uses a cantilevered support for supporting baffles in a stripping vessel. Only one end of the support is fastened to a wall of a contacting conduit or a wall of the stripping vessel and the other end is spaced apart from the near wall of the contacting conduit or the stripping vessel. The arrangement provides for easier maintenance and accommodates differential thermal expansion.

Abstract: A device for finishing the corner of an impression of the profile. Corners of impressions of doors manufactured in one-piece are shaped to give the appearance of a mitered joint where a joint does not exist. By selecting the appropriate cutter, sides of the corners of differing profiles can be mitered to corresponding forty-five degree angles relative to the square of the corner.

Abstract: Square inside corners are formed in raised panels from a single workpiece to be used in the manufacture of cabinetry, furniture and the like. A machine with a rotatable spindle provides the drive for the square corner forming tool bit. The tool bit is mounted on a support that translates the rotary motion of the spindle to a reciprocating motion of the tool bit. The tool bit has a pair of side wall surfaces that are displaced at an angle equal to one half the angle formed by the corner, relative to the line of travel of the tool bit. The lower edges of the side wall surfaces are formed with cutting blades, ridges, or abrasive surfaces or, alternatively, the bottom wall surface of the tool bit is formed with such cutting edges.

Abstract: An apparatus for machining a square inside corner on a workpiece. The apparatus comprises a rotatable shaft, a device cooperating with the shaft for transferring the rotating motion of the shaft to transverse oscillating motion, and a cutting tool mounted to the device and moving in the transverse oscillating motion. The cutting tool preferably includes a blade contoured to produce the desired cutting surface. Both edges of the blade are cutting edges and are disposed at a 45.degree. angle. The device comprises a pin mounted on and offset from the shaft, a sliding plate to which the cutting tool is mounted, and a pair of sliding sleeves on either side of the sliding plate. The sliding plate includes an elongated slot to receiving the pin so that as the shaft rotates, the pin is moved within the slot causing the sliding plate to slide transversely within the sliding sleeves to provide the transverse oscillating motion.

Abstract: A machine and method for forming an inside corner portion in a one-piece article material where the inside corner portion is produced by the meeting at a corner of first and second adjacent profiles defined by grooves or members. The inside corner portion at the corner is formed by machining the article material to form portions of the profiles not including the entirity of the inside corner portion, and then shearing the article material in the corner to form the inside corner portion. The machine has first and second cutter assemblies each having a shear cutter. Each shear cutter is mounted for movement along a path between retracted and extended positions such that the path of movement of the cutter of the first assembly meets with the path of movement of the cutter of the second assembly. The article having partial profiles formed therein is mounted with the cutter's positioned and seated with the profiles and such that the profiles are aligned along the paths of movement of the cutters.
