Title: Move-out queue buffer
Inventor: THOMAS JEFFREY A
IPC: G06F12/08
Filed: 1987-09-18
Granted: 1991-10-01
Abstract: ABSTRACT      A queue buffer used for the controlled buffering and transferal of data between a cache memory of a central processor unit and a mainstore memory unit is described.  The queue buffer of the present invention preferably includes a buffer memory for the queued storage of data and a controller for directing the nominally immediate acceptance and storage of data received direct from a cache memory and for the nominally systematic background transfer of data from the queue buffer to the mainstore memory unit.  This nominal prioritization of memory transfers with respect to the queue buffer memory allows data move-in requests requiring data from the main storage unit to proceed while required move-out data is moved from a cache memory immediately to the buffer queue memory.

Title: Well fluid sampling apparatus
Inventor: CHRISTENSEN JON B
IPC: E21B47/06
Filed: 1988-06-16
Granted: 1991-09-24
Abstract: Abstract A well fluid sampling apparatus for sampling fluids from a formation reservoir  in a well.   The sampling apparatus comprises a body portion defining a large sampling chamber therein  and at  least one sampler module disposed in the sampling chamber.   The sampler module is adapted for sepa-rately entrapping a volume of fluid as the sampling chamber fills.  A sliding sampler valve is moved to open a sampler port allowing formation fluid to enter the sampling chamber. The sampler module has a metering piston therein which auto-matically closes after a predetermined volume of fluid has entered  a  sampler  module  chamber defined  in  the  sampler module.   The metering is accomplished by a chamber filled with a viscous  liquid which must be discharged through a small  orifice  as  the  piston moves  in  response  to  fluid pressure  in  the sampling chamber.   The viscous fluid is discharged into an air chamber.  Testing gauges may be posi-tioned adjacent each of the sampler modules to measure and record fluid pressure and temperature as desired.  A surface drain nipple may be connected to a portion of the sampler module for moving the metering piston to an open position for draining the fluid from the sampler module chamber.   A drain collar and drain nipple may be attached to the sampler module  adjacent  the  hole  therein  for draining  through  a drain line and appropriate valving.  The sampling apparatus may be used as a portion of a perforate, test and sample tool which also includes a packer and perforating guns.  No portion of the fluid entrapped in the sampler goes above the packer or enters the tool string.

Title: Calibration of fluid delivery equipment
Inventor: GILL DAVID C
IPC: G01F25/00
Filed: 1988-06-28
Granted: 1992-02-11
Abstract: ABSTRACT      The flow rate of a fluid, such as a herbicide, from delivery equipment is established by causing the fluid to flow into a calibration vessel (14), and measuring the volume which flows in a predetermined time.  The vessel (14) is connected to a delivery head (8) of the equipment by an intermediate component (16). A tube (54) provides a passage for venting air from the vessel (14) as fluid flows into it.  After a calibration measurement, the fluid can be returned to the equipment by inverting the equipment.  The outgoing fluid is then replaced by air flowing back through the tube (54).

Abstract: Abstract of the Disclosure Both  a method and apparatus for  electrolytically removing radioactive metal ions from a  decontamination solution  to  regenerate the solution and  prepare the ions  for disposal as disclosed herein.   At least  the cathodic   portion  of  the  electrode  used  in   the electrolysis  is  formed from a  combustible  material, such as a semi-fluidized bed of graphite particles.  In the  method  of  the  invention,   the  decontamination solution  is  passed  in  intimate contact  with   the graphite  particles forming the cathodic portion of the electrode  as an electric potential is applied  to  the electrode.   As a result of the electric potential, the metal  ions  are  detached  from  the  chelate  in the decontamination   solution   and  deposited  onto   the graphite  particles  of  the cathodic  portion  of  the electrode.   After the electrode becomes spent,  it  is incinerated  in  order  to  reduce the  volume  of  the resulting radioactive ash.  The gases produced from the incineration  are scrubbed with a scrubbing  liquid  to remove    radioactive  particles    therefrom.     The contaminated scrubbing liquid is in turn used to form a cementitious  substance or grout which encapsulates the radioactive  ash.    The  invention  provides  a   more effective  method  of  removing radioactive  ions  from decontamination  solutions,  and  does not  create  any radioactive eluants.   The resulting solid waste is  of small volume.
