Abstract: VIDEO BANDWITH REDUCTION SYSTEM EMPLOYING INTERFRAME BLOCK DIFFERENCING       AND TRANSFORM DOMAIN CODING    ABSTRACT OF THE DISCLOSURE Video type information signals are compressed for transmission and reproduction by comparing corresponding blocks of time domain information signals from successive fields, converting a block of the time domain information signals to a transform domain signal represented by discrete cosine transform coefficients when the difference between the corresponding blocks exceeds a block difference threshold, and encoding the transform domain coefficients for transmission to a decoding site.  Corresponding blocks of time domain information signals from successive fields are compared by storing the successive fields in memory on a pixel by pixel basis, retrieving each block on a pixel by pixel basis, forming the difference between corresponding pixels from the successive blocks, squaring the resulting difference signal, summing the squares and dividing by the number of pixels per block.  Successive fields are merged by weighted summing of corresponding pixels.           Blocks are converted by first transforming individual samples along the horizontal direction, and then transforming the same block samples along the vertical direction, the transformed coefficients being stored in a diagonal memory unit along with a block address code and block averaged quadrature chrominance characters.  Each converted block stored in the diagonal memory is encoded using a plurality of unique code tables.  A dedicated block address code table is constructed using a unique algorithm; the remaining code tables are Huffman coded tables, one dedicated to the D.C. transform coefficient term, two other tables dedicated to the quadrature component characters, and the remaining tables (including the two chloma tables) being selected on a coefficient by coefficient basis using an algorithm based on the predictive mean value of the cosine coefficient terms.  The cosine coefficient terms are also (a) quantized prior to encoding by dividing the coefficient by a variable parametric value Dk, which is a measure of the fullness of the transmission buffer, and which is changed in value after each block of codes is loaded into the buffer. The Dk value is also used to adjust the value of the block difference threshold.          The block codes are assembled in a transmission buffer in the order of generation and are transmitted to a decoding site along with initialization values for Dk and a buffer fullness parameter Bk.          At the decoding site, the received code characters are decoded using an inverse processing resulting in recapture of the initial video signals.          The luminance and chrominance components are initially processed by subsampling and averaging to produce further compression.     (b)

Abstract: WELL TOOL                   ABSTRACT           A well tool carried in a drill string for maintaining bottom hole contact while absorbing angular and axial shock forces of a rotating drill bit.  The tool has an elongated body with pipe joint ends and includes a tubular mandrel rotationally and slideably mounted within a tubular barrel.  A groove (preferably helical) and roller connection guides the mandrel from the barrel during drilling.  Resilient shock absorbing members between metal guide rings are carried between stop elements on the mandrel and barrel.  Shock forces are absorbed initially by the rotating/telescoping movements of the mandrel within the barrel.  Excess shock forces are absorbed in the members acted on by the stop elements on further inward/outward movements of the mandrel rotating in the barrel.  Unique cross-over rings (graphite-filled TeflonR) cushion the resilient members from impacts of the metal guide rings.

Abstract: REAR PORTION SUPPORTING MECHANISM IN APPARATUS FOR MACHINING ELONGATED WORKPIECES     ABSTRACT     Apparatus for successive cut-off operations at axially spaced locations along an elongated tubular work-piece wherein the workpiece is rotated during cut-off opera-tions and successively advanced axially between such opera-tions.  The cut-off operations occur at a work station where a front portion of the workpiece is successively advanced, rotated and severed with an elongated portion of the work-piece extending rearwardly from the work station.  A pair of elongated guide and support rails extend adjacent the rear-wardly projecting portion of the workpiece and mount a work-piece supporting mechanism which is freely moveable there along toward and away from the work station.  The mechanism comprises a freely rotatable collet assembly adapted to grip and release the workpiece.  Operating means for the collet assembly comprise a handwheel, a gear train, and a shell cam which is rotatable through a limited angle and axially move-able at the urging of the handwheel and gear train.  Axial cam movement results in axial movement of a collet actuating sleeve to open the collet and a compression spring closes the collet.  An auxiliary collet opening arm mounted on the shell cam is engaged by a fluid operated cylinder to rotate the cam and automatically open the collet when the workpiece supporting mechanism is incrementally drawn forwardly along the guide rails by the successively advancing workpiece to a position of proximity with the work station.
