Title: Striking tool, head and handle and methods of manufacturing
Inventor: KRAUTH WALTER K
IPC: B25D1/00
Filed: 1988-08-16
Granted: 1991-10-29
Abstract: ABSTRACT     Striking tools, heads and handles for such tools, and methods of manufacturing them.  A tool head according to this invention employs a flange which extends from each side of the head between the forward and rear portions of the head.  The portion of the head within the periphery of each flange is generally concave and narrows to form a web extending longitudinally in the striking direction to connect the forward and rear portions.  The web may include at least one opening communicating between the two concave surfaces.  The flanges increase the cross-sectional area and moment of inertia of the head relative to the striking direction and relative to the handle axis.  The resulting head enjoys greater strength and resistance to translational forces, bending moments, deformation and potential failure.  Portions of the handle extending through the opening in the head and thereby about portions of the head reduce the possibility that the head will leave the handle as the tool is being swung.  A minimum of surfaces required to be machined reduces finishing labor and expense.

Title: Method & system for synchronization of an auxiliary sound source which may contain multiple language channels to motion picture film, video tape, or other picture source containing a sound track
Inventor: KARAMON JOHN J
IPC: G03B31/04
Filed: 1988-12-13
Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE         Method, system and apparatus correlate an audio message of an auxiliary sound source with an audio message from a sound track of motion picture film, video tape or other picture source with accompanying audio message track.  This auxiliary source contains multiple language channels (also called "translation tracks" or "translation sound channels") running synchronously with each other.  One such channel is a "prime language channel" including an audio message carrying the same information (possibly higher quality) in the same language as the message in the track accompanying the motion picture.  This prime channel is derived from the same "master recording" (or high quality duplicate thereof) as the track accompanying the motion picture.          Consequently the audio message conveyed by the prime channel (at higher quality) is the same audio message conveyed by the motion picture track, but signals carrying those two messages may be quite different from each other:  digital signal versus analog signal.  Inherent characteristics, e.g., "syllabic structure", "absolute value envelope", of the two messages (not the signals themselves) are used for correlation to achieve synchronization.          Having synchronized the prime channel with motion picture track by message correlation, other language channels automatically become synchronized with the track.  Consequently, their articulation as heard corresponds with lip-motions seen in the motion picture.  An audience (or its segments) may select any desired available language while viewing the motion picture.  The correlation system notes any sound track breaks for providing corresponding fast-forward jumps in all language channels during subsequent picture presentations.

Abstract: Abstract A corrugated container blank stacker 10 is described for receiving rows of container blanks 12 from a sheet cutter and for stacking the container blanks in rows of stacks on a pallet. In the embodiment shown the stacker is able to receive container blanks in rows of three abreast and then forming three rows of stacks, three abreast, on a pallet. The stacker includes a transfer conveyor means 30 with vacuum belts 72 normally in alignment with the sheet cutter 16 for longitudinally spacing the rows of blanks, removing loose trim sheet material, and accurately placing the rows of blanks on a main conveyor 32. The main conveyor 32 has vacuum belts for conveying the rows of blanks in an arc path to an elevated position at a stacking station.     At the stacking station, the rows of blanks are propelled against a backstop 160 and then descend onto a stripper plate 196 that is incremental downward to form a row of partial stacks.          The partial stacks are deposited onto a pallet 36 supported on an elevator platform 151. The pallet 36 is indexed downward to form a row of completed stacks. The pallet 36 is then lowered beneath the backstop and indexed forward to position the completed row of stacks behind the backstop. The pallet 36 is then again raised to receive a second row of stacks. The process is repeated until the ballet is full of stacks before it is conveyed from the stacker 10 and a new pallet is brought into place.

Abstract: ABSTRACT OF THE DISCLOSURE          An apparatus for generating a high quality image from a digital video signal includes a system for gamma correcting the digital video signal with a digital look up table and for converting the resultant digital signal to an analog video signal.  Another circuit generates a triangular wave reference pattern signal and a comparator compares the analog video signal with the triangular wave reference pattern signal to form a pulse-width-modulated signal.  A raster scanning print engine producing, for example, a laser beam, scans over a recording medium in accordance with the pulse-width-modulated signal, thereby forming an image of high quality on the recording medium of a print engine.  This apparatus can also be used with an analog video signal by first converting the analog video signal to a digital video signal with an analog to digital converter.
