Granted: 1998-06-16
Abstract: A  method  for  removing  unpleasant  organoleptic sensations  from  polydextrose-containing  confections  is disclosed.   Polydextrose solutions ranging from 50 to 70% are pH-adjusted from their typical pH of between 2.5 to 3.5 to levels of between about 4 to about 7,  preferably of between about 4.5 to 6.5, and most preferably from about 5 to  about  6.   The polydextrose  solutions  are  thereafter heated  to  form  confectionery  syrups  and  hard  candy  is thereafter made in the customary way.  Confections prepared in  accordance  with  this method  are  low  calorie  and of superior taste and mouth feel compared to non-pH-adjusted polydextrose  confections.    In  the  cases  where  it  is necessary to re-acidify hard candy syrups for particular confectionery formulas, it has been found that the choice of acidulants,  preferably  malic  and  adipic  acids,  provide superior confections.

Filed: 1992-07-03
Granted: 1998-12-08
Abstract: The    Video   Insertion   Processing   System   (VIPS) architecture provides the system architect with a modular and parallel approach to graphic processing.  Using a core set of graphic modules, a wide range of graphic processing requirements can be satisfied.  By providing the capability to support independent graphic paths, the performance can increase by N times for each set of graphic paths added. The use  of  independent  graphic paths  also  increases  the systems capability to meet real time response requirements. The key to the VIPS architecture is the ability to merge images from multiple frame buffers  into a single display image.  The final image is a result of selecting each pixel source based on the pixel s priority.   This provides the graphics  system  with  the  capability  of  image  overlay, underlay, merge and hide regardless of shape or size.   A parallel pipelined approach provides the VIPS architecture with the capability of merging multiple  images generated from the different graphic paths on a pixel by pixel basis without degradation of overall system performance.

Abstract: A balanced essentially vibration-free hand-grippable fluid powered reciprocating blade cutting tool intended primarily for cutting poultry, fish and meat for processing.  The tool includes a hollow handle which functions as a motor housing.  Fitting means are provided for connecting the housing to a source of fluid under pressure and for exhausting fluid from the housing.  A reciprocable cutting blade extends forwardly from the handle.  A fluid actuated motor within the handle housing includes a pair of aligned piston assemblies of approximately equal weight.  The pistons are reciprocable in opposite directions.  The cutting blade is secured to one of these pistons.    A control valve and fluid flow passages within the housing and associated with the fluid inlet fitting permits fluid to be directed alternately to the inner and outer sides of the pistons for causing the pistons to alternately move toward one another and away from one another.  Manually operable trigger means control the flow of fluid into the housing.  The angle of the cutting blade relative to the handle is variable to further reduce fatigue and other problems associated with rotation of the wrist, which is a contributing cause of carpal tunnel syndrome.
