Granted: 1998-04-28
Abstract: There is disclosed a motion signal processor for use in a digital video signal processing system. The device spatially spreads the motion signal over a specific value by detecting the maximum value of an image window and then reconstructs the motion adaptively by using the spread motion signal according to the spatial motion area of the motion signal. A maximum value circuit 128 determines the maximum value of the spatial lowpass filtered frame difference signal so as to provide the motion signal with spatial  correlation.  The maximum value  is  compared with a predetermined reference level by a comparator 124. Then, an area detector 130 reconstructs the motion signal area of the signal output of the comparator to adaptively smooth the motion signal.          A K value generator generates motion factors by processing the area detection signal. Therefore, the motion signal is spread smoothly, based on the spatial correlation by virtue of the spatial spreading of the temporal motion signal of the frame difference signal and by means of the motion signal reconstructed by the spatial correlation of the motion signal.

The deflector forms a forward axial air stream component and a rearward axial air stream component.  Exhaust openings are formed in the sidewalls of the combine to vent the forward air stream component. An exhaust gap is formed at the rear of the axial separator to vent the rearward air stream component.

Title: Method and composition for improving the high temperature gel stability of borated galactomannans
Inventor: DAWSON JEFFREY C
IPC: C08B37/00
Filed: 1992-04-08
Granted: 1996-12-17
Abstract: A complexor solution and method of use are shown for providing controlled delay and improved high temperature gel stability of borated fracturing fluids.   A base fluid is first prepared by blending together an aqueous fluid and a hydratable  polymer  which  is  capable  of  gelling  in  the presence of borate  ions.   The complexor  is prepared by mixing  a  cross-linking  additive   capable  of  furnishing borate ions in solution with a delay additive. The delay additive  is  effective,  within  a  selected  pH  range,  to chemically bond with both boric acid and the borate ions produced by the cross-linking additive to thereby limit the number of borate ions initially available in solution for subsequent cross-linking of the hydratable polysaccharide. In addition to providing more precise control of the delay time,  the  complexor provides  a  reserve  of  borate which provides improved gel stability at higher temperatures.
