Abstract: ABSTRACT OF THE DISCLOSURE      A valve trim cage assembly for anti-cavitation control valves comprises a plurality of concentrically nested, cylindrical sleeves with fluid flow constricting annular channels defined between adjacent sleeves.  Each sleeve has an identical multiplicity of radial plenum holes contained therein which serve as expansion chambers, each plenum hole intersecting at least one flow constricting channel to provide tortuous fluid flow paths of alternating expansion plenum holes and constricted annular channels radially through the cage assembly.  The cross sectional area of the channels increase from sleeve to sleeve in the direction of fluid flow to provide staged and gradually decreasing pressure reduction as the flow proceeds through the cage assembly.  The area of the plenum holes is much greater than the total cross sectional area of all annular channels intersecting the plenum hole such that the channels are always flow restricting and the plenums are expansion chambers.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus acts upon an extrudate rope to form individual elements of predetermined size and shape which  elements  are  separated  from  one  another  a predetermined  distance.    A  die  is  used  having  a predetermined shape with indentations therein to press the extrudate rope against a support at predetermined locations.   A conveyor belt  is  used to  carry  the extrudate  rope  in  one  direction,  and  the  die  is supported such that during the pressing operation the die  forward speed matches  the extrudate rope forward speed.  A supporting table underlies the conveyor belt.          The die has a pair of generally spherical indentations for shaping pieces from the extrudate rope.  The die is formed of a non-stick material such as Teflon?.   A chamber is located in an opposite surface of the die from each respective indentation, to serve as a plenum fluid supply to the indentations, bores connecting the respective opposing chambers to respective indentations.          The   fluid   pressure   in   each   indentation   assists separation of a shaped piece of the extrudate rope from respective indentations. A plurality of extrudate ropes may be formed into pieces simultaneously,  by using a plurality of dies in parallel, thereby allowing fast and economical  separation  of  the  extrudate  ropes  into pieces.

Abstract: Abstract of the Disclosure Data for a histogram is provided through generation of a pseudo-random sequence in a shift register connected in predetermined feedback relation.  A histogram element storage location is addressed in a random access memory and is used for loading the shift register in parallel when an event corresponding to that element takes place. The shift register proceeds from that point to increment a pseudo-random sequence for the duration of the event, and the concluding value of the sequence is loaded back into the random access memory location at the conclusion of the event.  A network between the random access memory and the shift register loads the shift register with a pattern that replicates the pattern that would exist in the shift register if the shift register had already been loaded and the data therein was shifted once.
